Sec. 301.6511(d)-2  Overpayment of income tax on account of net operating 
loss or capital loss carrybacks.

    (a) Special period of limitation. (1) If the claim for credit or 
refund relates to an overpayment of income tax attributable to a net 
operating loss carryback (provided in section 172(b)), or a capital loss 
carryback (provided in section 1212(a)), then in lieu of the 3-year 
period from the time the return was filed in which the claim may be 
filed or credit or refund allowed, as prescribed in section 6511 (a) or 
(b), the period shall be whichever of the following two periods expires 
later:
    (i) The period which ends with the expiration of the 15th day of the 
40th month (or 39th month, in the case of a corporation) following the 
end of the taxable year of the net operating loss or net capital loss 
which resulted in the carryback; or
    (ii) The period which ends with the expiration of the period 
prescribed in section 6511(c) within which a claim for credit or refund 
may be filed with respect to the taxable year of the net operating loss 
or net capital loss which resulted in the carryback except that--
    (a) With respect to an overpayment attributable to a net operating 
loss carryback to any year on account of a certification issued to the 
taxpayer under section 317 of the Trade Expansion Act of 1962, the 
period shall not expire before the expiration of the sixth month 
following the month in

[[Page 381]]

which such certification is issued to the taxpayer, and
    (b) With respect to an overpayment attributable to the creation of, 
or an increase in, a net operating loss as a result of the elimination 
of excessive profits by a renegotiation (as defined in section 
1481(a)(1)(A) ), the period shall not expire before September 1, 1959, 
or the expiration of the 12th month following the month in which the 
agreement or order for the elimination of such excessive profits becomes 
final, whichever is the later.
    (2) In the case of a claim for credit or refund involving a net 
operating loss or capital loss carryback described in subparagraph (1) 
of this paragraph (a), the amount of the credit or refund may exceed the 
portion of the tax paid within the period provided in section 6511 
(b)(2) or (c), whichever is applicable, to the extent of the amount of 
the overpayment attributable to the carryback. If the claim involves an 
overpayment based not only on a net operating loss or capital loss 
carryback described in subparagraph (1) of this paragraph (a), but based 
also on other items, the credit or refund cannot exceed the sum of the 
following:
    (i) The amount of the overpayment which is attributable to the net 
operating loss or capital loss carryback, and
    (ii) The balance of such overpayment up to a limit of the portion, 
if any, of the tax paid within the period provided in section 6511 
(b)(2) or (c), or within the period provided in any other applicable 
provision of law.
    (3) If the claim involves an overpayment based not only on a net 
operating loss or capital loss carryback described in subparagraph (1) 
of this paragraph (a), but based also on other items, and if the claim 
with respect to any items is barred by the expiration of any applicable 
period of limitation, the portion of the overpayment attributable to the 
items not so barred shall be determined by treating the allowance of 
such items as the first adjustment to be made in computing such 
overpayment. If a claim for credit or refund is not filed, and if credit 
or refund is not allowed, within the period prescribed in this 
paragraph, then credit or refund may be allowed or made only if claim 
therefor is filed, or if such credit or refund is allowed, within the 
period prescribed in section 6511 (a), (b), or (c), whichever is 
applicable, subject to the provisions thereof limiting the amount of 
credit or refund in the case of a claim filed, or if no claim was filed, 
in case of credit or refund allowed, within such applicable period. For 
the limitations on the allowance of interest for an overpayment where 
credit or refund is subject to the provisions of this section, see 
section 6611(f).
    (b)(1) Barred overpayments. If the allowance of a credit or refund 
of an overpayment of tax attributable to a net operating loss carryback 
or capital loss carryback 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 under the provisions of 
section 6511(d)(2)(B) if a claim therefor is filed within the period 
provided by section 6511(d)(2)(A) and paragraph (a) of this section for 
filing a claim for credit or refund of an overpayment attributable to a 
carryback. Similarly, if the allowance of an application, credit, or 
refund of a decrease in the tax determined under 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 an application for a tentative carryback adjustment is filed 
within the period provided in section 6411(a). Thus, for example, even 
though the tax liability (not including the net operating loss deduction 
or capital loss carryback (or the effect of such deduction or 
carryback)) for a given taxable year has previously been litigated 
before the Tax Court, credit or refund of an overpayment may be allowed 
or made despite the provisions of section 6512(a), if claim for such 
credit or refund is filed within the period provided in section 
6511(d)(2)(A) and paragraph (a) of this section. In the case of a claim 
for credit or refund of an overpayment attributable to a carryback, or 
in the case of an application for a tentative carryback adjustment, the 
determination of any court, including the Tax Court, in any proceeding 
in which the decision of the court has become final, shall be conclusive 
except

[[Page 382]]

with respect to the net operating loss deduction, and the effect of such 
deduction, or with respect to the determination of a short-term capital 
loss, and the effect of such short-term capital loss, to the extent that 
such deduction or short-term capital loss is affected by a carryback 
which was not in issue in such proceeding.
    (2) For purposes of the special period of limitation for filing a 
claim for credit or refund of an overpayment of tax with respect to a 
computation year (as defined in section 1302(c)(1)) by an individual who 
has chosen to compute his tax under sections 1301 through 1305 (relating 
to income averaging), such claim is determined to relate to an 
overpayment attributable to a net operating loss carryback when such 
carryback relates to any base period year (as defined in section 
1302(c)(3)). Thus, if (i) an individual has a net operating loss for a 
taxable year subsequent to a taxable year for which he had chosen the 
benefits of income averaging, and (ii) such net operating loss carryback 
is wholly utilized in any one or more of his base period years (which 
would result in an increased amount of averageable income for such 
computation year), the special period of limitation with respect to such 
individual's computation year applies and a timely claim for credit or 
refund with respect to the computation year may be filed.
