26 U.S. Code § 6245 - Secretarial authority
The Secretary is authorized and directed to make adjustments at the partnership level in any partnership item to the extent necessary to have such item be treated in the manner required.
If the Secretary determines that a partnership adjustment is required, the Secretary is authorized to send notice of such adjustment to the partnership by certified mail or registered mail. Such notice shall be sufficient if mailed to the partnership at its last known address even if the partnership has terminated its existence.
If the Secretary mails a notice of a partnership adjustment to any partnership for any partnership taxable year and the partnership files a petition under section 6247 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 Any notice so rescinded shall not be treated as a notice of a partnership adjustment, for purposes of this section, section 6246, and section 6247, and the taxpayer shall have no right to bring a proceeding under section 6247 with respect to such notice. Nothing in this subsection shall affect any suspension of the running of any period of limitations during any period during which the rescinded notice was outstanding.
Pub. L. 114–74, title XI, § 1101(b)(2), (g), Nov. 2, 2015, 129 Stat. 625, 638, provided that, applicable to returns filed for partnership taxable years beginning after Dec. 31, 2017, with certain exceptions, this section is repealed.
