26 CFR 1.1314(a)-2 - Adjustment to other barred taxable years.
(1) The tax liability for such other year or years must be affected, or must have been treated as affected, by a net operating loss deduction (as defined in section 172) or by a capital loss carryback or carryover (as defined in section 1212).
(3) On the date of the determination the adjustment with respect to such other year or years must be prevented by some law or rule of law, other than sections 1311 through 1315 and section 7122 and the corresponding provisions of prior revenue laws.
(b) The amount of the adjustment for such other year or years shall be computed in a manner similar to that provided in § 1.1314(a)-1. The tax previously determined for such other year or years shall be ascertained. A recomputation must then be made to ascertain the increase or decrease in tax, if any, resulting solely from the correction of the net operating loss deduction or capital loss carryback or carryover. The difference between the tax previously determined and the tax as recomputed is the amount of the adjustment. In the recomputation, no consideration shall be given to items other than the following:
(c) A net operating loss deduction or a capital loss carryback or carryover determined with reference to the year of the error may affect, or may have been treated as affecting, a taxable year with respect to which an adjustment is not prevented by the operation of any law or rule of law. In such case, the appropriate adjustment shall be made with respect to such open taxable year. However, the redetermination of the tax for such open taxable year is not made pursuant to part II (section 1311 and following), subchapter Q, chapter 1 of the Code, and the adjustment for such open year and the method of computation are not limited by the provisions of said sections.
(d) The application of this section may be illustrated by the following example:
(i) A Tax Court decision entered in 1957 with respect to the taxable year 1953 constituted a determination under which an adjustment is authorized to the taxable year 1950, the year with respect to which the error was made. This adjustment increases income for said year by $15,000, so that instead of a net operating loss of $14,000, its corrected net income is $1,000 for 1950, and the tax computed on that income will be assessed as a deficiency for 1950. An adjustment is authorized under this section with respect to each of the years 1949 and 1951, as the tax liability for each year was treated as affected by a net operating loss deduction which was determined by a computation in which reference was made to the year 1950. In the recomputation of the tax for 1949, the net operating loss carryback from 1950 will be eliminated, and in the recomputation of the tax for 1951 the net operating loss carryover from 1950 will be eliminated; for each of the years 1949 and 1951 there will be an adjustment which will be treated as a deficiency for said year.
(ii) Assuming the same facts, except that the correction with respect to the year 1950 increases the net operating loss for said year from $14,000 to $20,000. As a result of this correction, there will be no change in the tax due for 1949 and 1950. However, the net operating loss deduction for 1951 is recomputed to be $19,000, the aggregate of the $10,000 carryover from 1950 and the $9,000 carryback from 1952 (the carryover from 1950 is the excess of the $20,000 net operating loss for 1950 over the $10,000 net income for 1949, such 1949 income being determined without any net operating loss deduction). As a result of the correction of the net operating loss deduction for 1951, the tax recomputation will show no tax due for said year, and the adjustment for 1951 will result in a refund or credit of the tax previously paid. Moreover, computations resulting from this adjustment will disclose a net operating loss carryover from 1952 to 1953 of $4,000, that is, the excess of the $9,000 net operating loss for 1952 over the $5,000 net income for 1951 (such net income for 1951 being computed as the $15,000 reduced by the carryover of $10,000 from 1950, the carryback from 1952 not being taken into account). A further adjustment is authorized under section 1311 with respect to any subsequent barred year in which the tax liability is affected by a carryover of the net operating loss from 1952, inasmuch as such carryover from 1952 has been determined by a computation in which reference was made to 1950, the taxable year of the error.
