26 U.S. Code § 6223 - Notice to partners of proceedings
If a group of partners in the aggregate having a 5 percent or more interest in the profits of a partnership so request and designate one of their members to receive the notice, the member so designated shall be treated as a partner to whom subsection (a) applies.
Except as provided in paragraphs (2) and (3), the Secretary shall use the names, addresses, and profits interests shown on the partnership return.
The Secretary shall use additional information furnished to him by the tax matters partner or any other person in accordance with regulations prescribed by the Secretary.
The Secretary shall mail the notice specified in paragraph (1) of subsection (a) to each partner entitled to such notice not later than the 120th day before the day on which the notice specified in paragraph (2) of subsection (a) is mailed to the tax matters partner.
The Secretary shall mail the notice specified in paragraph (2) of subsection (a) to each partner entitled to such notice not later than the 60th day after the day on which the notice specified in such paragraph (2) was mailed to the tax matters partner.
This subsection applies where the Secretary has failed to mail any notice specified in subsection (a) to a partner entitled to such notice within the period specified in subsection (d).
If the Secretary mails a notice of final partnership administrative adjustment for a partnership taxable year with respect to a partner, the Secretary may not mail another such notice to such partner with respect to the same taxable year of the same partnership in the absence of a showing of fraud, malfeasance, or misrepresentation of a material fact.
To the extent and in the manner provided by regulations, the tax matters partner of a partnership shall keep each partner informed of all administrative and judicial proceedings for the adjustment at the partnership level of partnership items.
If a pass-thru partner receives a notice with respect to a partnership proceeding from the Secretary, the tax matters partner, or another pass-thru partner, the pass-thru partner shall, within 30 days of receiving that notice, forward a copy of that notice to the person or persons holding an interest (through the pass-thru partner) in the profits or losses of the partnership for the partnership taxable year to which the notice relates.
