26 U.S. Code § 992 - Requirements of a domestic international sales corporation
The Secretary shall prescribe regulations setting forth the conditions under and the extent to which a corporation which has filed a return as a DISC for a taxable year shall be treated as a DISC for such taxable year for all purposes of this title, notwithstanding the fact that the corporation has failed to satisfy the conditions of paragraph (1).
For purposes of this title, the term “former DISC” means, with respect to any taxable year, a corporation which is not a DISC for such year but was a DISC in a preceding taxable year and at the beginning of the taxable year has undistributed previously taxed income or accumulated DISC income.
If a corporation makes an election under paragraph (1), then the provisions of this part shall apply to such corporation for the taxable year of the corporation for which made and for all succeeding taxable years and shall apply to each person who at any time is a shareholder of such corporation for all periods on or after the first day of the first taxable year of the corporation for which the election is effective.
