(3) Treatment of certain wholly owned subsidiaries (A) In general Except as provided in regulations prescribed by the Secretary, for purposes of this title— (i) a corporation which is a qualified subchapter S subsidiary shall not be treated as a separate corporation, and (ii) all assets, liabilities, and items of income, deduction, and credit of a qualified subchapter S subsidiary shall be treated as assets, liabilities, and such items (as the case may be) of the S corporation. (B) Qualified subchapter S subsidiary For purposes of this paragraph, the term “qualified subchapter S subsidiary” means any domestic corporation which is not an ineligible corporation (as defined in paragraph (2)), if— (i) 100 percent of the stock of such corporation is held by the S corporation, and (ii) the S corporation elects to treat such corporation as a qualified subchapter S subsidiary. (C) Treatment of terminations of qualified subchapter S subsidiary status (i) In general For purposes of this title, if any corporation which was a qualified subchapter S subsidiary ceases to meet the requirements of subparagraph (B), such corporation shall be treated as a new corporation acquiring all of its assets (and assuming all of its liabilities) immediately before such cessation from the S corporation in exchange for its stock. (ii) Termination by reason of sale of stock If the failure to meet the requirements of subparagraph (B) is by reason of the sale of stock of a corporation which is a qualified subchapter S subsidiary, the sale of such stock shall be treated as if— (I) the sale were a sale of an undivided interest in the assets of such corporation (based on the percentage of the corporation’s stock sold), and (II) the sale were followed by an acquisition by such corporation of all of its assets (and the assumption by such corporation of all of its liabilities) in a transaction to which section 351 applies. (D) Election after termination If a corporation’s status as a qualified subchapter S subsidiary terminates, such corporation (and any successor corporation) shall not be eligible to make— (i) an election under subparagraph (B)(ii) to be treated as a qualified subchapter S subsidiary, or (ii) an election under section 1362(a) to be treated as an S corporation, before its 5th taxable year which begins after the 1st taxable year for which such termination was effective, unless the Secretary consents to such election. (E) Information returns Except to the extent provided by the Secretary, this paragraph shall not apply to part III of subchapter A of chapter 61 (relating to information returns).
