In general. This section applies in any case in which the Internal Revenue Service fails to timely mail any notice described in section 6223(a) of the Internal Revenue Code to a partner entitled to such notice within the period specified in section 6223(d). The failure to issue any notice within the period specified in section 6223(d) does not invalidate the notice of the beginning of an administrative proceeding or final partnership administrative adjustment (FPAA). An untimely FPAA enables the recipient of the untimely notice to make the elections described in paragraphs (b), (c), and (d) of this section. The period within which to make the elections described in paragraphs (b), (c), and (d) of this section commences with the mailing of an FPAA to the partner. In the absence of an election, paragraphs (b) and (c) of this section provide for the treatment of a partner's partnership items.

Proceeding finished. If at the time the Internal Revenue Service mails the partner an FPAA—

The period within which a petition for review of the FPAA under section 6226 may be filed has expired and no petition has been filed; or

The decision of a court in an action begun by such a petition has become final, the partner may elect in accordance with paragraph (d) of this section to have that adjustment, that decision, or a settlement agreement described in section 6224(c)(2) with respect to the partnership taxable year to which the adjustment relates apply to that partner. If the partner does not make an election in accordance with paragraph (d) of this section, the partnership items of the partner for the partnership taxable year to which the proceeding relates shall be treated as having become nonpartnership items as of the day on which the Internal Revenue Service mails the partner the FPAA.

Proceeding still going on. If at the time the Internal Revenue Service mails the partner an FPAA, paragraphs (b)(1) and (2) of this section do not apply, the partner shall be a party to the proceeding unless the partner elects, in accordance with paragraph (d) of this section, to have—

A settlement agreement described in section 6224(c)(2) with respect to the partnership taxable year to which the proceeding relates apply to the partner; or

The partnership items of the partner for the partnership taxable year to which the proceeding relates treated as having become nonpartnership items as of the day on which the Internal Revenue Service mails the partner the FPAA.

Election—(1) In general. The election described in paragraph (b) or (c) of this section shall be made in the manner prescribed in this paragraph (d). The election shall apply to all partnership items for the partnership taxable year to which the election relates.

Time and manner of making election. The election shall be made by filing a statement with the Internal Revenue Service office mailing the FPAA within 45 days after the date on which the FPAA was mailed to the partner making the election.
