TAXPAYER DUE PROCESS ENHANCEMENT ACT

← Ways and Means CommitteeView on GovInfo →

Summary

H. Rpt. 119-428 accompanies tax legislation related to federal tax provisions. Tax bills modify the Internal Revenue Code — the federal tax statute — either by creating new provisions, extending expiring ones, or changing existing rules that affect individuals, businesses, or specific industries. The Ways and Means Committee prepared this report to explain the tax changes, estimate their revenue impact (how much they cost or raise), and describe who is affected. Tax reports are technical documents that include detailed analysis from the Joint Committee on Taxation (JCT) and often reveal the policy priorities driving tax changes.

                section, and
                  ``(B) shall not result in a suspension of the running

                lapse of a deadline, a court filing, or a court order 
                establishes that the taxpayer has forfeited or 
                otherwise lost the right to pursue such dispute.''.

                    LIABILITY DURING COLLECTION ACTION PROCEEDINGS.

        if any portion of such period is after the date of the 
        enactment of this Act.

        rules to lien hearings.--The amendment made by subsection (b) 
        shall take effect on the date of the enactment of this Act.

SEC. 4. EXPANSION OF JURISDICTION OF TAX COURT.

                under this section, the person may, within 30 days of 
                such determination, petition the Tax Court for review 
                of--

                          ``(ii) any underlying tax liability referred 
                        to in subsection (c)(2)(B) which is properly

                          ``(ii) any underlying tax liability referred

                proposed collection action at issue in such 
                determination.''.

                       I. SUMMARY AND BACKGROUND

                         A. Purpose and Summary

    The bill, H.R. 6506, the ``Taxpayer Due Process Enhancement 
Act,'' as amended, was ordered reported by the Committee on 
Ways and Means on December 10, 2025.
    The bill provides additional safeguards for taxpayers 
contesting collection actions by the Internal Revenue Service 
(``IRS''). Specifically, the bill suspends the period of 
limitations for filing certain claims for credit or refund 
while certain collection action disputes are pending, prohibits 
the IRS from crediting overpayments against certain tax 
liabilities at issue in collection action disputes, and 
provides the United States Tax Court with continuing 
jurisdiction over collection determinations and certain tax 
liabilities in collection action disputes.

                 B. Background and Need for Legislation

    The U.S. Tax Court is a federal trial court established by 
Congress under Article I of the Constitution which specializes 
in adjudicating disputes over federal income tax, generally 
prior to formal tax assessments made by the IRS. The Tax Court 
is the only forum in which taxpayers may litigate tax matters 
without having first paid the disputed tax in full. If a 
taxpayer owes federal taxes and does not pay, in most cases the 
IRS can issue a levy on the taxpayer's property or file a lien 
notice against the taxpayer's property. The IRS must inform the 
taxpayer by notice before making the levy or within five days 
of filing the notice of lien, and the IRS's notice must 
indicate the taxpayer's right to request a hearing with the IRS 
Independent Office of Appeals to dispute the collection action, 
generally called a ``collection due process'' hearing. After 
IRS Appeals issues a determination from a collection due 
process hearing, the taxpayer can petition the Tax Court to 
challenge that decision.
    In June 2025, the Supreme Court ruled in Commissioner v. 
Zuch that the Tax Court cannot hear a CDP appeal if the IRS 
drops its levy and chooses a different method to take the 
taxpayer's assets. The Court also said the IRS acted properly 
when it used the taxpayer's refunds to settle disputed tax 
liability. This legislation is a response to the Supreme 
Court's ruling with the goal of ensuring that taxpayers' due 
process rights are protected.
    This bill suspends the period of limitations for filing a 
claim for credit or refund during a CDP proceeding, giving 
taxpayers an extended opportunity to receive their refunds; 
blocks the IRS from applying a taxpayer's overpayments to any 
tax they are currently disputing, meaning the IRS cannot use a 
taxpayer's old refunds against them during collection action 
proceedings; and expands the Tax Court's collection due process 
jurisdiction, so taxpayers can choose Tax Court over district 
court, which is more accessible and cheaper.

                         C. Legislative History

Background

    H.R. 6506 was introduced on December 9, 2025, and was 
referred to the Committee on Ways and Means.

                         D. Designated Hearing

    Pursuant to clause 3(c)(6) of rule XIII, the following 
hearing was used to develop and consider H.R. 6506:
    On February 11, 2025, the Committee on Ways and Means 
Oversight Subcommittee held a hearing titled, ``IRS Return on 
Investment and the Need for Modernization'' to examine the lack 
of return on investment from funding provided to the IRS by the 
Inflation Reduction Act and the need for information technology

                      II. EXPLANATION OF THE BILL

         A. Collection Due Process Hearings, Tax Court Review,
                    and Claims for Credit or Refund

                              PRESENT LAW

Collection due process hearings

    When a taxpayer neglects or refuses to pay an internal 
revenue tax liability, in most cases the Internal Revenue 
Service (``IRS'') may levy on the taxpayer's property or file a 
notice of Federal tax lien against the taxpayer's property.\1\ 
Generally the IRS must inform the taxpayer by notice before 
making the levy or within five days of filing the notice of 
lien, and the notice must indicate the taxpayer's right to 
request a hearing with the IRS Independent Office of Appeals 
(``IRS Appeals'') to dispute the collection action, generally 
called a ``collection due process'' hearing.\2\ If the taxpayer 
properly requests a hearing, the IRS Appeals officer generally 
must (1) verify that the requirements of any applicable law or 
administrative procedure relating to the collection action have 
been met, (2) consider any relevant issues raised by the 
taxpayer, including collection alternatives such as an 
installment agreement or offer-in-compromise, and (3) determine 
whether the collection action balances the need for efficient 
collection of taxes with the taxpayer's legitimate concern that 
collection be no more intrusive than necessary.\3\
---------------------------------------------------------------------------
    \1\Secs. 6321, 6331.
    \2\Secs. 6320(a), 6330(a).
    \3\Sec. 6330(c).
---------------------------------------------------------------------------
    The taxpayer may raise challenges to the existence or 
amount of the underlying tax liability only if the taxpayer did 
not receive a notice of deficiency for the liability or did not 
otherwise have a prior opportunity to dispute the liability.\4\ 
Examples of a prior opportunity include (1) a bankruptcy case 
in which the IRS filed a proof of claim for the liability 
(whether or not the taxpayer disputed the claim),\5\ and (2) an 
opportunity (whether or not availed of) for a conference with 
IRS Appeals regarding the liability, unless the liability is 
for a tax subject to deficiency procedures.\6\
---------------------------------------------------------------------------
    \4\Sec. 6330(c)(2)(B).
    \5\See, e.g., Kendricks v. Commissioner, 124 T.C. 69 (2005).
    \6\Treas. Reg. sec. 301.6330-1(e)(3), Q&A-E2; Lewis v. 
Commissioner, 128 T.C. 48 (2007). The taxes subject to deficiency 
procedures are income tax, gift tax, estate tax, and certain excise 
taxes. See secs. 6211(a), 6212(a).
---------------------------------------------------------------------------
    The taxpayer generally may not raise an issue (including an 
underlying tax liability) at a collection due process hearing 
if, among other reasons, the issue was raised and considered at 
a previous collection due process hearing or in any other 
previous administrative or judicial proceeding in which the 
taxpayer meaningfully participated.\7\
---------------------------------------------------------------------------
    \7\Sec. 6330(c)(4)(A).
---------------------------------------------------------------------------
    Once a taxpayer has properly requested a collection due 
process hearing relating to a proposed levy, in most cases the 
IRS may not pursue a levy for the tax liability at issue for 
the duration of the hearing and any appeals of the hearing 
determination.\8\ Also, the following periods of limitation 
generally are suspended for the duration of the hearing and any 
appeals:\9\ (1) any period of limitation for the post-
assessment collection of a tax liability regarding which the 
hearing was requested (typically a 10-year period),\10\ (2) any 
period of limitation to bring criminal charges against the 
taxpayer with respect to a tax liability regarding which the 
hearing was requested (typically a three- or six-year period 
following commission of the offense),\11\ (3) any period of 
limitation for the taxpayer to bring suit against the United 
States to remedy the wrongful collection of a tax regarding 
which the hearing was requested (typically a two-year period 
following the IRS's disallowance of the prerequisite claim for 
credit or refund),\12\ (4) any period of limitation for the 
United States to bring suit against the taxpayer to recover an 
erroneous refund of a tax regarding which the hearing was 
requested (typically a two-year period following the making of 
the refund),\13\ and (5) any period of limitation for certain 
third parties to bring suit against the United States relating 
to levies and liens used to collect a tax regarding which the 
hearing was requested (typically a two-year period following 
the levy or the sale of property subject to lien).\14\
---------------------------------------------------------------------------
    \8\Sec. 6330(e)(1); Treas. Reg. sec. 1.6330-1(g)(1). The 
prohibition on levy activity while an appeal is pending does not apply 
if the underlying tax liability is not at issue in the appeal and the 
court determines that the IRS has shown good cause not to suspend the 
levy. Sec. 6330(e)(2); see also sec. 6330(f) (providing that the 
collection due process protections generally do not apply in the 
following circumstances: (1) the IRS duly determines that collection of 
the tax in question is in jeopardy; (2) the IRS levies on a taxpayer's 
State tax refund; (3) the IRS levies to collect employment taxes owed 
by a person who requested a collection due process hearing with respect 
to unpaid employment taxes arising in the two-year period preceding the 
beginning of the taxable period in which the levy is served; and (4) 
the IRS levies on a Federal contractor).
    \9\Sec. 6330(e)(1); Treas. Reg. secs. 1.6330-1(g)(2) Q&A-G1, 
1.6320-1(g)(2) Q&A-G1.
    \10\See sec. 6502.
    \11\See sec. 6531.
    \12\See sec. 6532(a).
    \13\See sec. 6532(b).
    \14\See sec. 6532(c).
---------------------------------------------------------------------------
    The pendency of a collection due process hearing or an 
appeal therefrom does not affect the general rule that the IRS 
may credit overpayments made by the taxpayer for one tax and 
tax period to other taxes and tax periods with outstanding 
assessed liabilities.\15\ Therefore, while a collection due 
process hearing or appeal is pending, the IRS may credit 
overpayments for taxes and tax periods not at issue in the 
hearing or appeal against the tax liabilities subject to the 
liens or levies at issue in the hearing or appeal.
---------------------------------------------------------------------------
    \15\See sec. 6402(a).
---------------------------------------------------------------------------

Tax Court review

    Once IRS Appeals issues a notice of determination after a 
collection due process hearing, the taxpayer may file a 
petition with the United States Tax Court (``Tax Court'') to 
appeal the determination.\16\ The petition generally must be 
filed within 30 days of the mailing of the notice of 
determination.\17\ However, the Supreme Court has held that the 
30-day deadline is not jurisdictional (that is, the Tax Court 
has jurisdiction over late-filed petitions) and is subject to 
equitable tolling.\18\
---------------------------------------------------------------------------
    \16\Sec. 6330(d).
    \17\Sec. 6330(d)(1).
    \18\Boechler, P.C. v. Commissioner, 596 U.S. 199 (2022). 
``[E]quitable tolling pauses the running of, or `tolls,' a [period] of 
limitations when a litigant has pursued his rights diligently but some 
extraordinary circumstance prevents him from bringing a timely 
action.'' Lozano v. Montoya Alvarez, 572 U.S. 1, 10 (2014).
---------------------------------------------------------------------------
    In a collection due process appeal, the Tax Court considers 
a challenge to the underlying tax liability only if the 
taxpayer challenged the liability during the IRS Appeals 
hearing and was entitled to do so.\19\ When the underlying 
liability is reviewable, the Tax Court reviews it de novo (that 
is, not giving deference to the IRS's determination of the 
liability) and considers evidence introduced at trial beyond 
what is contained in the IRS's administrative record of the 
hearing.\20\
---------------------------------------------------------------------------
    \19\See Goza v. Commissioner, 114 T.C. 176, 181-82 (2000).
    \20\Ibid.; Jordan v. Commissioner, 134 T.C. 1, 8-9 (2010).
---------------------------------------------------------------------------
    In Commissioner v. Zuch, the Supreme Court held that the 
Tax Court loses jurisdiction over a collection due process 
appeal when, after the petition is filed, the IRS revokes its 
determination to maintain or pursue the lien or levy at issue--
for instance, because the IRS has applied the taxpayer's 
overpayments from other tax years to fully satisfy the 
liability at issue in the Tax Court case.\21\ Therefore, even 
if the underlying liability was otherwise reviewable, the Tax 
Court may not review it if the IRS revokes its 
determination.\22\ Instead, if the taxpayer believes that 
amounts have been improperly credited towards the alleged 
underlying liability, the taxpayer must fully pay the alleged 
liability (if not already fully paid) and, if the relevant 
period of limitations has not expired, may file a claim for 
credit or refund. If the IRS rejects the claim or fails to act 
on it, the taxpayer may file suit in a U.S. district court or 
the U.S. Court of Federal Claims.\23\

Limitations on claims for credit or refund

    If a taxpayer wishes to recover an overpayment\24\ of any 
internal revenue tax, generally the taxpayer must file a claim 
for credit or refund with the IRS within three years of filing 
the relevant tax return or (if later) within two years of 
paying the tax.\25\ If the taxpayer did not file a return for 
the tax in question, the claim must be filed within two years 
of paying the tax.\26\ If the taxpayer and the IRS have 
executed an agreement to extend the period for assessing a tax 
(which normally runs for three years after the return is 
filed),\27\ and the agreement was executed before the 
expiration of the usual period for filing a claim for credit or 
refund of the tax at issue, then the deadline for filing the 
claim typically is extended to six months after the agreed-upon 
deadline for assessment.\28\
---------------------------------------------------------------------------
    \24\According to the Supreme Court, an overpayment occurs ``when a 
taxpayer pays more than is owed, for whatever reason or no reason at 
all.'' United States v. Dalm, 494 U.S. 596, 609 n.6 (1990). Section 
6401(a) also provides: ``The term `overpayment' includes that part of 
the amount of the payment of any internal revenue tax which is assessed 
or collected after the expiration of the period of limitation properly 
applicable thereto.''
    \25\Sec. 6511(a). If the IRS determines, in response to a timely 
claim, that an overpayment was made, generally it may credit the 
overpayment (plus interest) against any other internal revenue tax 
liabilities of the taxpayer and refund the balance, if any. Sec. 
6402(a).
    \26\Sec. 6511(a).
    \27\See sec. 6501(a), (c)(4).
    \28\Sec. 6511(c)(1).
---------------------------------------------------------------------------
    The normal period of limitations for filing a claim for 
credit or refund may be replaced by or supplemented with a 
longer or additional period in certain enumerated cases, such 
as an overpayment attributable to a deduction for a worthless 
debt or security (in which case the claim may be filed within 
seven years of the due date for the relevant return) or an 
overpayment attributable to the foreign tax credit (in which 
case the claim may be filed within 10 years of the due date for 
filing a return for the year in which the foreign taxes were 
paid or accrued).\29\ Additionally, the normal period of 
limitations generally is suspended for an individual taxpayer 
during periods when that taxpayer is financially disabled.\30\
---------------------------------------------------------------------------
    \29\See sec. 6511(d); see also secs. 547(b)(2), 1314(b), 2014(e), 
2058(b), 6013(b)(3)(B), 6411, 6427(i)(2), 6512(b), 7508(a)(1)(E), 
7508A.
    \30\Sec. 6511(h). For these purposes, an individual is financially 
disabled if such individual is unable to manage his financial affairs 
by reason of a medically determinable physical or mental impairment 
which can be expected to result in death or which has lasted or can be 
expected to last for a continuous period of not less than 12 months. 
Sec. 6511(h)(2)(A).
---------------------------------------------------------------------------
    Even if a taxpayer properly and timely files a claim for 
credit or refund, the amount of credit or refund allowed may 
not exceed the amount of the relevant tax paid during the 
applicable ``lookback'' period. If the claim for credit or 
refund was filed within three years of filing the relevant tax 
return, the lookback period generally is the three years (plus 
any extension of time granted for filing the return) 
immediately preceding the filing of the claim.\31\ If the claim 
for credit or refund was filed within two years of paying the 
tax but more than three years after filing the relevant return, 
the lookback period generally is the two years immediately 
preceding the filing of the claim.\32\ If the IRS allows a 
credit or refund other than in response to a filed claim, the 
lookback period is the period that would apply if the taxpayer 
had filed a claim on the date the credit or refund is 
allowed.\33\ In cases where the taxpayer and the IRS have 
executed an agreement to extend the period for assessing a tax, 
and a claim is filed (or a credit or refund otherwise allowed) 
after the agreement's execution and before the expiration of 
six months following the agreed-upon assessment deadline, the 
amount of credit or refund allowed with respect to the tax in 
question may not exceed the sum of (1) the amount of the tax 
paid in the lookback period that would apply if a claim had 
been filed on the date of the agreement's execution, plus (2) 
the amount of the tax paid between the agreement's execution 
and the filing of the claim (or the making of the credit or 
refund).\34\

                           REASONS FOR CHANGE

    The Committee believes that the IRS should not be permitted 
to credit overpayments against tax liabilities that are 
properly under dispute in a collection due process hearing or 
appeal. The Committee further believes that taxpayers properly 
disputing the IRS's assertion of tax liability in a collection 
due process hearing or appeal should have an extension of time 
to file a claim for credit or refund regarding that liability. 
Finally, the Committee does not believe that the IRS should be 
able to deprive the Tax Court of jurisdiction over a collection 
due process determination or an underlying liability dispute 
simply by abandoning collection efforts.

                      B. Explanation of Provisions

Suspension of period of limitations on filing a claim for credit or 
        refund during collection due process proceedings

    If a taxpayer requests a collection due process hearing, 
the provision in some cases suspends the running of the normal 
period of limitations for filing a claim for credit or refund 
from the date the IRS receives the taxpayer's hearing request 
until the hearing concludes and all appeal rights have lapsed 
or been exhausted. The suspension applies only to a claim for 
credit or refund of a tax properly disputed at the hearing, and 
the suspension ends after any date on which a lapse of a 
deadline, a court filing, or a court order establishes that the 
taxpayer has forfeited or otherwise lost the right to dispute 
the amount of the tax liability.
    The suspension provided by the provision applies to the 
extended period for filing a claim for credit or refund in the 
case of an agreement between the taxpayer and the IRS to extend 
the period for assessing tax,\35\ and it also applies to the 
lookback periods for determining the amount of credit or refund 
allowed in response to a timely claim.\36\ The suspension 
provided by the provision does not apply to the extended 
periods of limitations for certain enumerated types of 
overpayments, such as those attributable to a deduction for a 
worthless debt or security or the foreign tax credit.\37\
---------------------------------------------------------------------------
    \35\See sec. 6511(c).
    \36\See sec. 6511(b), (c)(2). For example, if the taxpayer pays a 
tax on Date 1, properly requests a collection due process hearing 
related to that tax on Date 2, and files a claim for credit or refund 
related to that tax on Date 3 (the first date on which the hearing and 
all appeals have ended), and the conditions for suspension apply, the 
lookback period does not include the period between Dates 2 and 3 
(i.e., the period during which the hearing and appeals were pending).
    \37\See e.g., sec. 6511(d).
---------------------------------------------------------------------------

Prohibition on crediting of overpayments against disputed tax liability 
        during collection action proceedings

    In the case of a taxpayer who properly disputes the 
liability amount at a collection due process hearing, the 
provision generally prohibits the IRS, from the time it 
receives the hearing request until the hearing concludes and 
all appeal rights have lapsed or been exhausted, from crediting 
any overpayments made by the taxpayer for other taxes or tax 
periods against the liability in dispute. The prohibition may 
be waived by the taxpayer, and the prohibition ends after any 
date on which a lapse of a deadline, a court filing, or a court 
order establishes that the taxpayer has forfeited or otherwise 
lost the right to dispute the amount of the tax liability.

Expansion of the Tax Court's collection due process jurisdiction

    The provision provides that when a taxpayer files a Tax 
Court petition to contest a collection due process hearing 
determination to sustain a lien or levy, the Tax Court acquires 
jurisdiction not only over the determination (as under present 
law) but also and independently over the tax liability amount, 
in cases where the taxpayer properly disputed the liability 
amount at the hearing and petitions for review of it. The 
provision provides that the Tax Court retains jurisdiction over 
both the hearing determination and the liability amount whether 
or not the IRS abandons any lien or proposed levy at issue. 
Accordingly, the provision abrogates the Supreme Court's 
holding in Commissioner v. Zuch.

                           C. Effective Date

    The part of the provision concerning the suspension of the 
period of limitations for filing a claim for credit or refund 
applies to any period of limitations that (as determined 
without regard to the amendments) ends on or after the date of 
enactment. The part of the provision concerning the crediting 
of overpayments during periods when certain collection due 
process hearings or appeals are pending applies to any such 
period if any portion of it falls after the date of enactment. 
The part of the provision concerning the jurisdiction of the 
Tax Court applies to petitions filed after the date of 
enactment.

    The Congressional Budget Act of 1974, as amended stipulates 
that revenue estimates provided by the staff of the Joint 
Committee on Taxation (``JCT'') will be the official estimates 
for all tax legislation considered by Congress. As such CBO 
incorporates these estimates into its cost estimates of the 
effects of the legislation. The estimates for the revenue

recommendations that are reflected in this report.

        B. Statement of General Performance Goals and Objectives

    With respect to clause 3(c)(4) of rule XIII of the Rules of 
the House of Representatives, the Committee advises that the 
bill does not authorize funding, so no statement of general 
performance goals and objectives is required.

    Rule XXI 5(b) of the Rules of the House of Representatives 
provides, in part, that ``A bill or joint resolution,

unless so determined by a vote of not less than three-fifths of 
the Members voting, a quorum being present.''
    The Committee has carefully reviewed the bill and states 
that the bill does not provide such a Federal income tax rate 
increase.

              D. Information Relating to Unfunded Mandates

    This information is provided in accordance with section 423 
of the Unfunded Mandates Reform Act of 1995 (Pub. L. No. 104-
4).
    The Committee has determined that the bill does not contain 
Federal mandates on the private sector. The Committee has 
determined that the bill does not impose a Federal 
intergovernmental mandate on State, local, or tribal 
governments.

            E. Congressional Earmarks, Limited Tax Benefits,
                      and Limited Tariff Benefits

    With respect to clause 9 of rule XXI of the Rules of the 
House of Representatives, the Committee has carefully reviewed 
the provisions of the bill, and states that the provisions of 
the bill do not contain any congressional earmarks, limited tax 
benefits, or limited tariff benefits within the meaning of the

    In compliance with clause 3(c)(5) of rule XIII of the Rules 
of the House of Representatives, the Committee states that no 
provision of the bill establishes or reauthorizes: (1) a 
program of the Federal Government known to be duplicative of 
another Federal program; (2) a program included in any report 
from the Government Accountability Office to Congress pursuant 
to section 21 of Public Law 111-139; or (3) a program related 
to a program identified in the most recent Catalog of Federal 
Domestic Assistance, published pursuant to the Federal Program 
Information Act (Pub. L. No. 95-220, as amended by Pub. L. No. 
98-169).

                       G. Tax Complexity Analysis

    Section 4022(b) of the Internal Revenue Service Reform and 
Restructuring Act of 1998 (the ``IRS Reform Act'') requires the 
staff of the Joint Committee on Taxation (in consultation with 
the Internal Revenue Service and the Treasury Department) to 
provide a tax complexity analysis. The complexity analysis is 
required for all legislation reported by the Senate Committee 
on Finance, the House Committee on Ways and Means, or any 
committee of conference if the legislation includes a provision 
that directly or indirectly amends the Internal Revenue Code 
and has widespread applicability to individuals or small 
businesses.

          (1) In general.--No levy may be made on any property 
        or right to property of any person unless the Secretary 
        has notified such person in writing of their right to a 
        hearing under this section before such levy is made. 
        Such notice shall be required only once for the taxable

                        procedures relating to such appeals;
                          (iv) the alternatives available to 
                        taxpayers which could prevent levy on

                        appropriateness of collection actions; 
                        and
                          (iii) offers of collection 
                        alternatives, which may include the 
                        posting of a bond, the substitution of 
                        other assets, an installment agreement, 
                        or an offer-in-compromise.
                  (B) Underlying liability.--The person may 
                also raise at the hearing challenges to the 
                existence or amount of the underlying tax 
                liability for any tax period if the person did 
                not receive any statutory notice of deficiency 
                for such tax liability or did not otherwise 
                have an opportunity to dispute such tax 
                liability.
          (3) Basis for the determination.--The determination 
        by an appeals officer under this subsection shall take 
        into consideration--
                  (A) the verification presented under 
                paragraph (1);
                  (B) the issues raised under paragraph (2); 
                and
                  (C) whether any proposed collection action 
                balances the need for the efficient collection 
                of taxes with the legitimate concern of the 
                person that any collection action be no more 
                intrusive than necessary.
          (4) Certain issues precluded.--An issue may not be 
        raised at the hearing if--
                  (A)(i) the issue was raised and considered at 
                a previous hearing under section 6320 or in any 
                other previous administrative or judicial 
                proceeding; and
                  (ii) the person seeking to raise the issue 
                participated meaningfully in such hearing or 
                proceeding;
                  (B) the issue meets the requirement of clause 
                (i) or (ii) of section 6702(b)(2)(A); or
                  (C) a final determination has been made with 
                respect to such issue in a proceeding brought 
                under subchapter C of chapter 63.
        This paragraph shall not apply to any issue with 
        respect to which subsection (d)(3)(B) applies.

                        referred to in subsection (c)(2)(B) 
                        which is properly disputed at the 
                        hearing in which such determination is 
                        made.
                  (B) Jurisdiction of tax court.--Upon the 
                filing of a petition, the Tax Court shall have 
                jurisdiction with respect to--
                          (i) the determination referred to in 
                        subparagraph (A)(i),
                          (ii) any underlying tax liability 
                        referred to in subparagraph (A)(ii),

                        subparagraph (A).
                  (C) Retention of jurisdiction.--Upon a 
                determination being made under this section, 
                subparagraphs (A) and (B) shall apply whether 
                or not the Secretary abandons the collection 
                action or proposed collection action at issue 
                in such determination.
          (2) Suspension of running of period for filing

        this section, the running of the period prescribed by 
        such subsection for filing such a petition with respect

        during which the person is so prohibited from filing 
        such a petition, and for 30 days thereafter.
          (3) Jurisdiction retained at IRS Independent Office 
        of Appeals.--The Internal Revenue Service Independent 
        Office of Appeals shall retain jurisdiction with 
        respect to any determination made under this section, 
        including subsequent hearings requested by the person 
        who requested the original hearing on issues 
        regarding--
                  (A) collection actions taken or proposed with 
                respect to such determination; and
                  (B) after the person has exhausted all 
                administrative remedies, a change in 
                circumstances with respect to such person which 
                affects such determination.
  (e) Suspension of collections and statute of limitations.--
          (1) In general.--Except as provided in paragraph (2), 
        if a hearing is requested under subsection (a)(3)(B), 
        the levy actions which are the subject of the requested 
        hearing and the running of any period of limitations 
        under section 6502 (relating to collection after 
        assessment), subsection (a), (b), or (c) of section 
        6511 (relating to limitations on credit or refund), 
        section 6531 (relating to criminal prosecutions), or 
        section 6532 (relating to other suits) shall be 
        suspended for the period during which such hearing, and 
        appeals therein, are pending. In no event shall any 
        such period expire before the 90th day after the day on 
        which there is a final determination in such hearing. 
        Notwithstanding the provisions of section 7421(a), the 
        beginning of a levy or proceeding during the time the 
        suspension under this paragraph is in force may be 
        enjoined by a proceeding in the proper court, including 
        the Tax Court. The Tax Court shall have no jurisdiction 
        under this paragraph to enjoin any action or proceeding 
        unless a timely appeal has been filed under subsection 
        (d)(1) and then only in respect of the unpaid tax or 
        proposed levy to which the determination being appealed 
        relates.
          (2) Levy upon appeal.--Paragraph (1) shall not apply 
        to a levy action while an appeal is pending if the 
        underlying tax liability is not at issue in the appeal 
        and the court determines that the Secretary has shown 
        good cause not to suspend the levy.
          (3) Period of limitations on filing a claim for 
        credit or refund.--In the case of the running of any 
        period of limitations under subsection (a), (b), or (c) 
        of section 6511 with respect to the filing of any claim 
        for credit or refund, paragraph (1)--
                  (A) shall apply only to the extent that such 
                credit or refund relates to an underlying tax 
                liability properly disputed at the hearing 
                requested under this section, and
                  (B) shall not result in a suspension of the 
                running of such period of limitations after any 
                date on which a lapse of a deadline, a court 
                filing, or a court order establishes that the 
                taxpayer has forfeited or otherwise lost the 
                right to pursue such dispute.
  (f) Exceptions.--If--
          (1) the Secretary has made a finding under the last 
        sentence of section 6331(a) that the collection of tax 
        is in jeopardy,
          (2) the Secretary has served a levy on a State to 
        collect a Federal tax liability from a State tax 
        refund,
          (3) the Secretary has served a disqualified 
        employment tax levy, or
          (4) the Secretary has served a Federal contractor 
        levy,
this section shall not apply, except that the taxpayer shall be 
given the opportunity for the hearing described in this section 
within a reasonable period of time after the levy.
  (g) Frivolous requests for hearing, etc..--Notwithstanding 
any other provision of this section, if the Secretary 
determines that any portion of a request for a hearing under 
this section or section 6320 meets the requirement of clause 
(i) or (ii) of section 6702(b)(2)(A), then the Secretary may 
treat such portion as if it were never submitted and such 
portion shall not be subject to any further administrative or 
judicial review.
  (h) Definitions related to exceptions.--For purposes of 
subsection (f)--
          (1) Disqualified employment tax levy.--A disqualified 
        employment tax levy is any levy in connection with the 
        collection of employment taxes for any taxable period 
        if the person subject to the levy (or any predecessor 
        thereof) requested a hearing under this section with 
        respect to unpaid employment taxes arising in the most 
        recent 2-year period before the beginning of the 
        taxable period with respect to which the levy is 
        served. For purposes of the preceding sentence, the 
        term ``employment taxes'' means any taxes under chapter 
        21, 22, 23, or 24.
          (2) Federal contractor levy.--A Federal contractor 
        levy is any levy if the person whose property is 
        subject to the levy (or any predecessor thereof) is a 
        Federal contractor.

              CHAPTER 65--ABATEMENTS, CREDITS, AND REFUNDS

Subchapter A--PROCEDURE IN GENERAL

           *       *       *       *       *       *       *

SEC. 6402. AUTHORITY TO MAKE CREDITS OR REFUNDS.

  (a) General rule.--In the case of any overpayment, the 
Secretary, within the applicable period of limitations, may 
credit the amount of such overpayment, including any interest 
allowed thereon, against any liability in respect of an 
internal revenue tax on the part of the person who made the 
overpayment and shall, subject to subsections (c), (d), (e), 
and (f), refund any balance to such person.
  (b) Credits against estimated tax.--The Secretary is 
authorized to prescribe regulations providing for the crediting 
against the estimated income tax for any taxable year of the 
amount determined by the taxpayer or the Secretary to be an 
overpayment of the income tax for a preceding taxable year.
  (c) Offset of past-due support against overpayments.--The 
amount of any overpayment to be refunded to the person making 
the overpayment shall be reduced by the amount of any past-due 
support (as defined in section 464(c) of the Social Security 
Act) owed by that person of which the Secretary has been 
notified by a State in accordance with section 464 of such Act. 
The Secretary shall remit the amount by which the overpayment 
is so reduced to the State collecting such support and notify 
the person making the overpayment that so much of the 
overpayment as was necessary to satisfy his obligation for 
past-due support has been paid to the State. The Secretary 
shall apply a reduction under this subsection first to an 
amount certified by the State as past due support under section 
464 of the Social Security Act before any other reductions 
allowed by law. This subsection shall be applied to an 
overpayment prior to its being credited to a person's future 
liability for an internal revenue tax. For purposes of this 
subsection, any reference to a State shall include a reference 
to any Indian tribe or tribal organization receiving a grant 
under section 455(f) of the Social Security Act.
  (d) Collection of debts owed to Federal agencies.--
          (1) In general.--Upon receiving notice from any 
        Federal agency that a named person owes a past-due 
        legally enforceable debt (other than past-due support 
        subject to the provisions of subsection (c)) to such 
        agency, the Secretary shall--
                  (A) reduce the amount of any overpayment 
                payable to such person by the amount of such 
                debt;
                  (B) pay the amount by which such overpayment 
                is reduced under subparagraph (A) to such 
                agency; and
                  (C) notify the person making such overpayment 
                that such overpayment has been reduced by an 
                amount necessary to satisfy such debt.
          (2) Priorities for offset.--Any overpayment by a 
        person shall be reduced pursuant to this subsection 
        after such overpayment is reduced pursuant to 
        subsection (c) with respect to past-due support 
        collected pursuant to an assignment under section 
        408(a)(3) of the Social Security Act (42 U.S.C. 
        608(a)(3)) and before such overpayment is reduced 
        pursuant to subsections (e) and (f) and before such 
        overpayment is credited to the future liability for tax 
        of such person pursuant to subsection (b). If the 
        Secretary receives notice from a Federal agency or 
        agencies of more than one debt subject to paragraph (1) 
        that is owed by a person to such agency or agencies, 
        any overpayment by such person shall be applied against 
        such debts in the order in which such debts accrued.
          (3) Treatment of OASDI overpayments.--
                  (A) Requirements.--Paragraph (1) shall apply 
                with respect to an OASDI overpayment only if 
                the requirements of paragraphs (1) and (2) of 
                section 3720A(f) of title 31, United States 
                Code, are met with respect to such overpayment.
                  (B) Notice; protection of other persons 
                filing joint return.--
                          (i) Notice.--In the case of a debt 
                        consisting of an OASDI overpayment, if 
                        the Secretary determines upon receipt 
                        of the notice referred to in paragraph 
                        (1) that the refund from which the 
                        reduction described in paragraph (1)(A) 
                        would be made is based upon a joint 
                        return, the Secretary shall--
                                  (I) notify each taxpayer 
                                filing such joint return that 
                                the reduction is being made 
                                from a refund based upon such 
                                return, and
                                  (II) include in such 
                                notification a description of 
                                the procedures to be followed, 
                                in the case of a joint return, 
                                to protect the share of the 
                                refund which may be payable to 
                                another person.
                          (ii) Adjustments based on protections 
                        given to other taxpayers on joint 
                        return.--If the other person filing a 
                        joint return with the person owing the 
                        OASDI overpayment takes appropriate 
                        action to secure his or her proper 
                        share of the refund subject to 
                        reduction under this subsection, the 
                        Secretary shall pay such share to such 
                        other person. The Secretary shall 
                        deduct the amount of such payment from 
                        amounts which are derived from 
                        subsequent reductions in refunds under 
                        this subsection and are payable to a 
                        trust fund referred to in subparagraph 
                        (C).
                  (C) Deposit of amount of reduction into 
                appropriate trust fund.--In lieu of payment, 
                pursuant to paragraph (1)(B), of the amount of 
                any reduction under this subsection to the 
                Commissioner of Social Security, the Secretary 
                shall deposit such amount in the Federal Old-
                Age and Survivors Insurance Trust Fund or the 
                Federal Disability Insurance Trust Fund, 
                whichever is certified to the Secretary as 
                appropriate by the Commissioner of Social 
                Security.
                  (D) OASDI overpayment.--For purposes of this 
                paragraph, the term ``OASDI overpayment'' means 
                any overpayment of benefits made to an 
                individual under title II of the Social 
                Security Act.
  (e) Collection of past-due, legally enforceable State income 
tax obligations.--
          (1) In general.--Upon receiving notice from any State 
        that a named person owes a past-due, legally 
        enforceable State income tax obligation to such State, 
        the Secretary shall, under such conditions as may be 
        prescribed by the Secretary--
                  (A) reduce the amount of any overpayment 
                payable to such person by the amount of such 
                State income tax obligation;
                  (B) pay the amount by which such overpayment 
                is reduced under subparagraph (A) to such State 
                and notify such State of such person's name, 
                taxpayer identification number, address, and 
                the amount collected; and
                  (C) notify the person making such overpayment 
                that the overpayment has been reduced by an 
                amount necessary to satisfy a past-due, legally 
                enforceable State income tax obligation.
        If an offset is made pursuant to a joint return, the 
        notice under subparagraph (B) shall include the names, 
        taxpayer identification numbers, and addresses of each 
        person filing such return.
          (2) Offset permitted only against residents of State 
        seeking offset.--Paragraph (1) shall apply to an 
        overpayment by any person for a taxable year only if 
        the address shown on the Federal return for such 
        taxable year of the overpayment is an address within 
        the State seeking the offset.
          (3) Priorities for offset.--Any overpayment by a 
        person shall be reduced pursuant to this subsection--
                  (A) after such overpayment is reduced 
                pursuant to--
                          (i) subsection (a) with respect to 
                        any liability for any internal revenue 
                        tax on the part of the person who made 
                        the overpayment;
                          (ii) subsection (c) with respect to 
                        past-due support; and
                          (iii) subsection (d) with respect to 
                        any past-due, legally enforceable debt 
                        owed to a Federal agency; and
                  (B) before such overpayment is credited to 
                the future liability for any Federal internal 
                revenue tax of such person pursuant to 
                subsection (b).
        If the Secretary receives notice from one or more 
        agencies of the State of more than one debt subject to 
        paragraph (1) or subsection (f) that is owed by such 
        person to such an agency, any overpayment by such 
        person shall be applied against such debts in the order 
        in which such debts accrued.
          (4) Notice; consideration of evidence.--No State may 
        take action under this subsection until such State--
                  (A) notifies by certified mail with return 
                receipt the person owing the past-due State 
                income tax liability that the State proposes to 
                take action pursuant to this section;
                  (B) gives such person at least 60 days to 
                present evidence that all or part of such 
                liability is not past-due or not legally 
                enforceable;
                  (C) considers any evidence presented by such 
                person and determines that an amount of such 
                debt is past-due and legally enforceable; and
                  (D) satisfies such other conditions as the 
                Secretary may prescribe to ensure that the 
                determination made under subparagraph (C) is 
                valid and that the State has made reasonable 
                efforts to obtain payment of such State income 
                tax obligation.
          (5) Past-due, legally enforceable State income tax 
        obligation.--For purposes of this subsection, the term 
        ``past-due, legally enforceable State income tax 
        obligation'' means a debt--
                  (A)(i) which resulted from--
                          (I) a judgment rendered by a court of 
                        competent jurisdiction which has 
                        determined an amount of State income 
                        tax to be due; or
                          (II) a determination after an 
                        administrative hearing which has 
                        determined an amount of State income 
                        tax to be due; and
                  (ii) which is no longer subject to judicial 
                review; or
                  (B) which resulted from a State income tax 
                which has been assessed but not collected, the 
                time for redetermination of which has expired, 
                and which has not been delinquent for more than 
                10 years.
        For purposes of this paragraph, the term ``State income 
        tax'' includes any local income tax administered by the 
        chief tax administration agency of the State.
          (6) Regulations.--The Secretary shall issue 
        regulations prescribing the time and manner in which 
        States must submit notices of past-due, legally 
        enforceable State income tax obligations and the 
        necessary information that must be contained in or 
        accompany such notices. The regulations shall specify 
        the types of State income taxes and the minimum amount 
        of debt to which the reduction procedure established by 
        paragraph (1) may be applied. The regulations may 
        require States to pay a fee to reimburse the Secretary 
        for the cost of applying such procedure. Any fee paid 
        to the Secretary pursuant to the preceding sentence 
        shall be used to reimburse appropriations which bore 
        all or part of the cost of applying such procedure.
          (7) Erroneous payment to State.--Any State receiving 
        notice from the Secretary that an erroneous payment has 
        been made to such State under paragraph (1) shall pay 
        promptly to the Secretary, in accordance with such 
        regulations as the Secretary may prescribe, an amount 
        equal to the amount of such erroneous payment (without 
        regard to whether any other amounts payable to such 
        State under such paragraph have been paid to such 
        State).
  (f) Collection of unemployment compensation debts.--
          (1) In general.--Upon receiving notice from any State 
        that a named person owes a covered unemployment 
        compensation debt to such State, the Secretary shall, 
        under such conditions as may be prescribed by the 
        Secretary--
                  (A) reduce the amount of any overpayment 
                payable to such person by the amount of such 
                covered unemployment compensation debt;
                  (B) pay the amount by which such overpayment 
                is reduced under subparagraph (A) to such State 
                and notify such State of such person's name, 
                taxpayer identification number, address, and 
                the amount collected; and
                  (C) notify the person making such overpayment 
                that the overpayment has been reduced by an 
                amount necessary to satisfy a covered 
                unemployment compensation debt.
        If an offset is made pursuant to a joint return, the 
        notice under subparagraph (C) shall include information 
        related to the rights of a spouse of a person subject 
        to such an offset.
          (2) Priorities for offset.--Any overpayment by a 
        person shall be reduced pursuant to this subsection--
                  (A) after such overpayment is reduced 
                pursuant to--
                          (i) subsection (a) with respect to 
                        any liability for any internal revenue 
                        tax on the part of the person who made 
                        the overpayment;
                          (ii) subsection (c) with respect to 
                        past-due support; and
                          (iii) subsection (d) with respect to 
                        any past-due, legally enforceable debt 
                        owed to a Federal agency; and
                  (B) before such overpayment is credited to 
                the future liability for any Federal internal 
                revenue tax of such person pursuant to 
                subsection (b).
        If the Secretary receives notice from a State or States 
        of more than one debt subject to paragraph (1) or 
        subsection (e) that is owed by a person to such State 
        or States, any overpayment by such person shall be 
        applied against such debts in the order in which such 
        debts accrued.
          (3) Notice; consideration of evidence.--No State may 
        take action under this subsection until such State--
                  (A) notifies the person owing the covered 
                unemployment compensation debt that the State 
                proposes to take action pursuant to this 
                section;
                  (B) provides such person at least 60 days to 
                present evidence that all or part of such 
                liability is not legally enforceable or is not 
                a covered unemployment compensation debt;
                  (C) considers any evidence presented by such 
                person and determines that an amount of such 
                debt is legally enforceable and is a covered 
                unemployment compensation debt; and
                  (D) satisfies such other conditions as the 
                Secretary may prescribe to ensure that the 
                determination made under subparagraph (C) is 
                valid and that the State has made reasonable 
                efforts to obtain payment of such covered 
                unemployment compensation debt.
          (4) Covered unemployment compensation debt.--For 
        purposes of this subsection, the term ``covered 
        unemployment compensation debt'' means--
                  (A) a past-due debt for erroneous payment of 
                unemployment compensation due to fraud or the 
                person's failure to report earnings which has 
                become final under the law of a State certified 
                by the Secretary of Labor pursuant to section 
                3304 and which remains uncollected;
                  (B) contributions due to the unemployment 
                fund of a State for which the State has 
                determined the person to be liable and which 
                remain uncollected; and
                  (C) any penalties and interest assessed on 
                such debt.
          (5) Regulations.--
                  (A) In general.--The Secretary may issue 
                regulations prescribing the time and manner in 
                which States must submit notices of covered 
                unemployment compensation debt and the 
                necessary information that must be contained in 
                or accompany such notices. The regulations may 
                specify the minimum amount of debt to which the 
                reduction procedure established by paragraph 
                (1) may be applied.
                  (B) Fee payable to Secretary.--The 
                regulations may require States to pay a fee to 
                the Secretary, which may be deducted from 
                amounts collected, to reimburse the Secretary 
                for the cost of applying such procedure. Any 
                fee paid to the Secretary pursuant to the 
                preceding sentence shall be used to reimburse 
                appropriations which bore all or part of the 
                cost of applying such procedure.
                  (C) Submission of notices through Secretary 
                of Labor.--The regulations may include a 
                requirement that States submit notices of 
                covered unemployment compensation debt to the 
                Secretary via the Secretary of Labor in 
                accordance with procedures established by the 
                Secretary of Labor. Such procedures may require 
                States to pay a fee to the Secretary of Labor 
                to reimburse the Secretary of Labor for the 
                costs of applying this subsection. Any such fee 
                shall be established in consultation with the 
                Secretary of the Treasury. Any fee paid to the 
                Secretary of Labor may be deducted from amounts 
                collected and shall be used to reimburse the 
                appropriation account which bore all or part of 
                the cost of applying this subsection.
          (6) Erroneous payment to State.--Any State receiving 
        notice from the Secretary that an erroneous payment has 
        been made to such State under paragraph (1) shall pay 
        promptly to the Secretary, in accordance with such 
        regulations as the Secretary may prescribe, an amount 
        equal to the amount of such erroneous payment (without 
        regard to whether any other amounts payable to such 
        State under such paragraph have been paid to such 
        State).
  (g) Review of reductions.--No court of the United States 
shall have jurisdiction to hear any action, whether legal or 
equitable, brought to restrain or review a reduction authorized 
by subsection (c), (d), (e), or (f). No such reduction shall be 
subject to review by the Secretary in an administrative 
proceeding. No action brought against the United States to 
recover the amount of any such reduction shall be considered to 
be a suit for refund of tax. This subsection does not preclude 
any legal, equitable, or administrative action against the 
Federal agency or State to which the amount of such reduction 
was paid or any such action against the Commissioner of Social 
Security which is otherwise available with respect to 
recoveries of overpayments of benefits under section 204 of the 
Social Security Act.
  (h) Federal agency.--For purposes of this section, the term 
``Federal agency'' means a department, agency, or 
instrumentality of the United States, and includes a Government 
corporation (as such term is defined in section 103 of title 5, 
United States Code).
  (i) Treatment of payments to States.--The Secretary may 
provide that, for purposes of determining interest, the payment 
of any amount withheld under subsection (c), (e), or (f) to a 
State shall be treated as a payment to the person or persons 
making the overpayment.
  (j) Cross reference.--For procedures relating to agency 
notification of the Secretary, see section 3721 of title 31, 
United States Code.
  (k) Refunds to certain fiduciaries of insolvent members of 
affiliated groups.--Notwithstanding any other provision of law, 
in the case of an insolvent corporation which is a member of an 
affiliated group of corporations filing a consolidated return 
for any taxable year and which is subject to a statutory or 
court-appointed fiduciary, the Secretary may by regulation 
provide that any refund for such taxable year may be paid on 
behalf of such insolvent corporation to such fiduciary to the 
extent that the Secretary determines that the refund is 
attributable to losses or credits of such insolvent 
corporation.
  (l) Explanation of reason for refund disallowance.--In the 
case of a disallowance of a claim for refund, the Secretary 
shall provide the taxpayer with an explanation for such 
disallowance.
  (m) Earliest date for certain refunds.--No credit or refund 
of an overpayment for a taxable year shall be made to a 
taxpayer before the 15th day of the second month following the 
close of such taxable year if a credit is allowed to such 
taxpayer under section 24 (by reason of subsection (d) thereof) 
or 32 for such taxable year.
  (n) Misdirected direct deposit refund.--Not later than the 
date which is 6 months after the date of the enactment of the 
Taxpayer First Act, the Secretary shall prescribe regulations 
to establish procedures to allow for--
          (1) taxpayers to report instances in which a refund 
        made by the Secretary by electronic funds transfer was 
        not transferred to the account of the taxpayer;
          (2) coordination with financial institutions for the 
        purpose of--
                  (A) identifying the accounts to which 
                transfers described in paragraph (1) were made; 
                and
                  (B) recovery of the amounts so transferred; 
                and
          (3) the refund to be delivered to the correct account 
        of the taxpayer.
  (o) Prohibition on Crediting of Overpayments Against Disputed 
Tax Liability During Collection Action Proceedings.--If a 
hearing is properly requested under section 6320(a)(3)(B) or 
6330(a)(3)(B), and an underlying tax liability referred to in 
section 6330(c)(2)(B) is properly disputed at such hearing, 
such tax liability shall not, except with the consent of the 
taxpayer, be taken into account under subsection (a) for the 
period during which the period of limitations for filing a 
claim for credit or refund relating to such tax liability is 
suspended by reason of section 6330(e).

                refund shall not exceed the portion of the tax 
                paid within the period, immediately preceding 
                the filing of the claim, equal to 3 years plus 
                the period of any extension of time for filing 
                the return. If the tax was required to be paid

                or refund shall not exceed the portion of the 
                tax paid within the 3 years immediately 
                preceding the filing of the claim.
                  (B) Limit where claim not filed within 3-year 
                period.--If the claim was not filed within such

                refund shall not exceed the portion of the tax 
                paid during the 2 years immediately preceding 
                the filing of the claim.
                  (C) Limit if no claim filed.--If no claim was

                the amount which would be allowable under 
                subparagraph (A) or (B), as the case may be, if 
                claim was filed on the date the credit or 
                refund is allowed.
  (c) Special rules applicable in case of extension of time by

        refund shall not exceed the portion of the tax paid 
        after the execution of the agreement and before the 
        filing of the claim or the making of the credit or 
        refund, as the case may be, plus the portion of the tax 
        paid within the period which would be applicable under 
        subsection (b)(2) if a claim had been filed on the date 
        the agreement was executed.
          (3) Claims not subject to special rule.--This

        filed, or credit or refund allowed if no claim is 
        filed, either--
                  (A) prior to the execution of the agreement 
                or
                  (B) more than 6 months after the expiration 
                of the period within which an assessment may be 
                made pursuant to the agreement or any extension 
                thereof.
  (d) Special rules applicable to income taxes.--
          (1) Seven-year period of limitation with respect to 
        bad debts and worthless securities.--If the claim for 
        credit or refund relates to an overpayment of tax 
        imposed by subtitle A on account of--
                  (A) The deductibility by the taxpayer, under 
                section 166 or section 832(c), of a debt as a 
                debt which became worthless, or, under section 
                165(g), of a loss from worthlessness of a 
                security, or
                  (B) The effect that the deductibility of a 
                debt or loss described in subparagraph (A) has 
                on the application to the taxpayer of a 
                carryover,
        in lieu of the 3-year period of limitation prescribed 
        in subsection (a), the period shall be 7 years from the 
        date prescribed by law for filing the return for the 
        year with respect to which the claim is made. If the 
        claim for credit or refund relates to an overpayment on 
        account of the effect that the deductibility of such a 
        debt or loss has on the application to the taxpayer of 
        a carryback, the period shall be either 7 years from 
        the date prescribed by law for filing the return for 
        the year of the net operating loss which results in 
        such carryback or the period prescribed in paragraph 
        (2) of this subsection, whichever expires the later. In 
        the case of a claim described in this paragraph the 
        amount of the credit or refund may exceed the portion 
        of the tax paid within the period prescribed in 
        subsection (b)(2) or (c), whichever is applicable, to 
        the extent of the amount of the overpayment 
        attributable to the deductibility of items described in 
        this paragraph.
          (2) Special period of limitation with respect to net 
        operating loss or capital loss carrybacks.--
                  (A) Period of limitation.--If the claim for 
                credit or refund relates to an overpayment 
                attributable to a net operating loss carryback 
                or a capital loss carryback, in lieu of the 3-
                year period of limitation prescribed in 
                subsection (a), the period shall be that period 
                which ends 3 years after the time prescribed by 
                law for filing the return (including extensions 
                thereof) for the taxable year of the net 
                operating loss or net capital loss which 
                results in such carryback, or the period 
                prescribed in subsection (c) in respect of such 
                taxable year, whichever expires later. In the 
                case of such a claim, the amount of the credit 
                or refund may exceed the portion of the tax 
                paid within the period provided in subsection 
                (b)(2) or (c), whichever is applicable, to the 
                extent of the amount of the overpayment 
                attributable to such carryback.
                  (B) Applicable rules.--
                          (i) In general.--If the allowance of 
                        a credit or refund of an overpayment of 
                        tax attributable to a net operating 
                        loss carryback or a capital loss 
                        carryback is otherwise prevented by the 
                        operation of any law or rule of law

                        compromises), such credit or refund may 
                        be allowed or made, if claim therefor 
                        is filed within the period provided in 
                        subparagraph (A) of this paragraph.

                        application, credit, or refund of a

                        section 6411(b) is otherwise prevented 
                        by the operation of any law or rule of 
                        law other than section 7122, such 
                        application, credit, or refund may be 
                        allowed or made if application for a 
                        tentative carryback adjustment is made 
                        within the period provided in section 
                        6411(a).

                        conclusive.--In the case of any such 
                        claim for credit or refund or any such 
                        application for a tentative carryback

                        court has become final, shall be 
                        conclusive except with respect to--
                                  (I) the net operating loss 
                                deduction and the effect of 
                                such deduction, and
                                  (II) the determination of a 
                                short-term capital loss and the 
                                effect of such short-term

                accordance with the provisions of section 901 
                or the provisions of any treaty to which the 
                United States is a party, in lieu of the 3-year 
                period of limitation prescribed in subsection

                year in which such taxes were actually paid or 
                accrued.
                  (B) Exception in the case of foreign taxes 
                paid or accrued.--In the case of a claim 
                described in subparagraph (A), the amount of

          (4) Special period of limitation with respect to 
        certain credit carrybacks.--
                  (A) Period of limitation.--If the claim for 
                credit or refund relates to an overpayment 
                attributable to a credit carryback, in lieu of 
                the 3-year period of limitation prescribed in 
                subsection (a), the period shall be that period 
                which ends 3 years after the time prescribed by

                carryback, or other credit carryback from a 
                subsequent taxable year, the period shall be 
                that period which ends 3 years after the time

                including extensions thereof, for such 
                subsequent taxable year) or the period 
                prescribed in subsection (c) in respect of such

                of law other than section 7122, relating to 
                compromises, such credit or refund may be 
                allowed or made, if claim therefor is filed 
                within the period provided in subparagraph (A) 
                of this paragraph. In the case of any such 
                claim for credit or refund, the determination 
                by any court, including the Tax Court, in any 
                proceeding in which the decision of the court

                respect to any credit, and the effect of such 
                credit, to the extent that such credit is 
                affected by a credit carryback which was not in 
                issue in such proceeding.

                of this paragraph, the term ``credit 
                carryback'' means any business carryback under 
                section 39.

        self-employment tax in certain cases.--If the claim for 
        credit or refund relates to an overpayment of the tax

        modification of an agreement, made pursuant to section 
        218 of the Social Security Act (relating to coverage of 
        State and local employees), and if the allowance of a 
        credit or refund of such overpayment is otherwise 
        prevented by the operation of any law or rule of law 
        other than section 7122 (relating to compromises), such 
        credit or refund may be allowed or made if claim 
        therefor is filed on or before the last day of the

        imposed by subtitle A on account of the recapture, 
        under section 4045 of the Employee Retirement Income 
        Security Act of 1974, of amounts included in income for 
        a prior taxable year, the 3-year period of limitation 
        prescribed in subsection (a) shall be extended, for 
        purposes of permitting a credit or refund of the amount 
        of the recapture, until the date which occurs one year 
        after the date on which such recaptured amount is paid 
        by the taxpayer.
          (7) Special period of limitation with respect to 
        self-employment tax in certain cases.--If--
                  (A) the claim for credit or refund relates to

                (relating to the tax on self-employment income) 
                attributable to Tax Court determination in a 
                proceeding under section 7436, and
                  (B) the allowance of a credit or refund of 
                such overpayment is otherwise prevented by the 
                operation of any law or rule of law other than 
                section 7122 (relating to compromises),
        such credit or refund may be allowed or made if claim 
        therefor is filed on or before the last day of the
