Notice of proceedings and adjustment

The Secretary shall mail to the partnership and the partnership representative— Any notice of a proposed partnership adjustment shall not be mailed later than the date determined under section 6235 (determined without regard to paragraphs (2) and (3) of subsection (a) thereof). Except to the extent that the partnership elects to waive the application of this subparagraph, any notice of a final partnership adjustment shall not be mailed earlier than 270 days after the date on which the notice of the proposed partnership adjustment is mailed. For the period of limitations on making adjustments, see section 6235. If the Secretary mails a notice of a final partnership adjustment to any partnership for any partnership taxable year and the partnership files a petition under section 6234 with respect to such notice, in the absence of a showing of fraud, malfeasance, or misrepresentation of a material fact, the Secretary shall not mail another such notice to such partnership with respect to such taxable year. The Secretary may, with the consent of the partnership, rescind any notice of a partnership adjustment mailed to such partnership. Any notice so rescinded shall not be treated as a notice of a partnership adjustment for purposes of this subchapter, and the taxpayer shall have no right to bring a proceeding under section 6234 with respect to such notice.
