Summary

When a corporation changes owners, limits are put on how much old tax credits and some losses it can use after the change. The amount you can use in later years is figured from the tax tied to the income that fits under the cap set by section 382, after applying section 382 and the related rules in parts (b) and (c) here. “Excess credit” means unused general business credits under section 39 and unused minimum tax credits under section 53. Unused net capital losses (section 1212) and excess foreign taxes (section 904(c)) are also limited by similar rules. Terms and some rules follow section 382 but are adjusted for credits and losses.

Title 26, §383

Internal Revenue Code — Source: USLM XML via OLRC

(a)(1)Under regulations, if an ownership change occurs with respect to a corporation, the amount of any excess credit for any taxable year which may be used in any post-change year shall be limited to an amount determined on the basis of the tax liability which is attributable to so much of the taxable income as does not exceed the section 382 limitation for such post-change year to the extent available after the application of section 382 and subsections (b) and (c) of this section.
(2)For purposes of paragraph (1), the term “excess credit” means—
(A)any unused general business credit of the corporation under section 39, and
(B)any unused minimum tax credit of the corporation under section 53.
(b)If an ownership change occurs with respect to a corporation, the amount of any net capital loss under section 1212 for any taxable year before the 1st post-change year which may be used in any post-change year shall be limited under regulations which shall be based on the principles applicable under section 382. Such regulations shall provide that any such net capital loss used in a post-change year shall reduce the section 382 limitation which is applied to pre-change losses under section 382 for such year.
(c)If an ownership change occurs with respect to a corporation, the amount of any excess foreign taxes under section 904(c) for any taxable year before the 1st post-change taxable year shall be limited under regulations which shall be consistent with purposes of this section and section 382.
(d)For purposes of this section, rules similar to the rules of subsections (b)(3) and (d)(1)(B) of section 382 shall apply.
(e)Terms used in this section shall have the same respective meanings as when used in section 382, except that appropriate adjustments shall be made to take into account that the limitations of this section apply to credits and net capital losses.
