Last updated Apr 6, 2026|Official source

Summary

Shareholders must report their pro rata share of an S corporation’s tax items on their own tax returns for the year the S corporation’s tax year ends (and for a shareholder who dies, or a trust or estate that ends, before the S corporation’s year ends). That includes two kinds of items: separately stated items (8 types of items, such as taxable and tax‑exempt income, losses, deductions, or credits that can change a shareholder’s tax) and nonseparately computed income or loss (gross income minus the corporation’s deductions, not counting the separately stated items). Each item keeps the same tax character it had to the corporation, and a shareholder’s gross income includes their share of the corporation’s gross income. Losses and deductions a shareholder can use are limited to the shareholder’s adjusted basis in the stock (as figured under the tax rules) plus any loan the shareholder made to the corporation. Any disallowed loss or deduction carries forward and is treated as happening in the next year for that shareholder (and, for certain transfers under section 1041, for the transferee). Special rules apply if the S status ends: disallowed losses from the corporation’s last S year are treated as incurred by the shareholder at the end of the post‑termination transition period, subject to basis limits and reductions. If a family member renders services or capital without reasonable pay, the IRS must adjust items to reflect the value provided. The credit under section 34 is excluded. Taxes under section 1374 are treated as corporate losses allocated to the built‑in gains, and taxes under section 1375 reduce each item of passive investment income proportionally.

Internal Revenue Code — Source: USLM XML via OLRC

(a)(1)In determining the tax under this chapter of a shareholder for the shareholder’s taxable year in which the taxable year of the S corporation ends (or for the final taxable year of a shareholder who dies, or of a trust or estate which terminates, before the end of the corporation’s taxable year), there shall be taken into account the shareholder’s pro rata share of the corporation’s—
(A)items of income (including tax-exempt income), loss, deduction, or credit the separate treatment of which could affect the liability for tax of any shareholder, and
(B)nonseparately computed income or loss.
(2)For purposes of this subchapter, the term “nonseparately computed income or loss” means gross income minus the deductions allowed to the corporation under this chapter, determined by excluding all items described in paragraph (1)(A).
(b)The character of any item included in a shareholder’s pro rata share under paragraph (1) of subsection (a) shall be determined as if such item were realized directly from the source from which realized by the corporation, or incurred in the same manner as incurred by the corporation.
(c)In any case where it is necessary to determine the gross income of a shareholder for purposes of this title, such gross income shall include the shareholder’s pro rata share of the gross income of the corporation.
(d)(1)The aggregate amount of losses and deductions taken into account by a shareholder under subsection (a) for any taxable year shall not exceed the sum of—
(A)the adjusted basis of the shareholder’s stock in the S corporation (determined with regard to paragraphs (1) and (2)(A) of section 1367(a) for the taxable year), and
(B)the shareholder’s adjusted basis of any indebtedness of the S corporation to the shareholder (determined without regard to any adjustment under paragraph (2) of section 1367(b) for the taxable year).
(2)(A)Except as provided in subparagraph (B), any loss or deduction which is disallowed for any taxable year by reason of paragraph (1) shall be treated as incurred by the corporation in the succeeding taxable year with respect to that shareholder.
(B)In the case of any transfer described in section 1041(a) of stock of an S corporation, any loss or deduction described in subparagraph (A) with respect such stock shall be treated as incurred by the corporation in the succeeding taxable year with respect to the transferee.
(3)(A)If for the last taxable year of a corporation for which it was an S corporation a loss or deduction was disallowed by reason of paragraph (1), such loss or deduction shall be treated as incurred by the shareholder on the last day of any post-termination transition period.
(B)The aggregate amount of losses and deductions taken into account by a shareholder under subparagraph (A) shall not exceed the adjusted basis of the shareholder’s stock in the corporation (determined at the close of the last day of the post-termination transition period and without regard to this paragraph).
(C)The shareholder’s basis in the stock of the corporation shall be reduced by the amount allowed as a deduction by reason of this paragraph.
(D)To the extent that any increase in adjusted basis described in subparagraph (B) would have increased the shareholder’s amount at risk under section 465 if such increase had occurred on the day preceding the commencement of the post-termination transition period, rules similar to the rules described in subparagraphs (A) through (C) shall apply to any losses disallowed by reason of section 465(a).
(4)In the case of any charitable contribution of property to which the second sentence of section 1367(a)(2) applies, paragraph (1) shall not apply to the extent of the excess (if any) of—
(A)the shareholder’s pro rata share of such contribution, over
(B)the shareholder’s pro rata share of the adjusted basis of such property.
(e)If an individual who is a member of the family (within the meaning of section 704(e)(2) of one or more shareholders of an S corporation renders services for the corporation or furnishes capital to the corporation without receiving reasonable compensation therefor, the Secretary shall make such adjustments in the items taken into account by such individual and such shareholders as may be necessary in order to reflect the value of such services or capital.
(f)(1)Subsection (a) shall not apply with respect to any credit allowable under section 34 (relating to certain uses of gasoline and special fuels).
(2)If any tax is imposed under section 1374 for any taxable year on an S corporation, for purposes of subsection (a), the amount so imposed shall be treated as a loss sustained by the S corporation during such taxable year. The character of such loss shall be determined by allocating the loss proportionately among the recognized built-in gains giving rise to such tax.
(3)If any tax is imposed under section 1375 for any taxable year on an S corporation, for purposes of subsection (a), each item of passive investment income shall be reduced by an amount which bears the same ratio to the amount of such tax as—
(A)the amount of such item, bears to
(B)the total passive investment income for the taxable year.
