(a) Election. Pursuant to section 1101(g)(4) of the Bipartisan Budget Act of 2015, Public Law 114-74 (BBA), a partnership may elect at the time and in such form and manner as described in this section for amendments made by section 1101 of the BBA, except section 6221(b) as added by the BBA, to apply to any return of the partnership filed for an eligible taxable year as defined in paragraph (d) of this section. An election is valid only if made in accordance with this section. Once made, an election may only be revoked with the consent of the Internal Revenue Service (IRS). An election is not valid if it frustrates the purposes of section 1101 of the BBA. A partnership may not request an extension of time under § 301.9100-3 for an election described in this section.

(b) Election on notification by the IRS—(1) Time for making the election. Except as described in paragraph (c) of this section, an election under this section must be made within 30 days of the date of notification to a partnership, in writing, that a return of the partnership for an eligible taxable year has been selected for examination (a notice of selection for examination).

(2) Form and manner of making the election—(i) In general. The partnership makes an election under this section by providing a written statement with the words “Election under Section 1101(g)(4)” written at the top that satisfies the requirements of paragraph (b)(2) of this section to the individual identified in the notice of selection for examination as the IRS contact regarding the examination.

(ii) Statement requirements. A statement making an election under this section must be in writing and be dated and signed by the tax matters partner, as defined under section 6231(a)(7) (prior to amendment by the BBA), and the applicable regulations, or an individual who has the authority to sign the partnership return for the taxable year under section 6063, the regulations thereunder, and applicable forms and instructions. The fact that an individual dates and signs the statement making the election described in this paragraph (b) shall be prima facie evidence that the individual is authorized to make the election on behalf of the partnership. A statement making an election must include—

(A) The partnership's name, taxpayer identification number, and the partnership taxable year for which the election described in this paragraph (b) is being made;

(B) The name, taxpayer identification number, address, and daytime telephone number of the individual who signs the statement;

(E) The following representations—

(1) The partnership is not insolvent and does not reasonably anticipate becoming insolvent before resolution of any adjustment with respect to the partnership taxable year for which the election described in this paragraph (b) is being made;

(2) The partnership has not filed, and does not reasonably anticipate filing, voluntarily a petition for relief under title 11 of the United States Code;

(3) The partnership is not subject to, and does not reasonably anticipate becoming subject to, an involuntary petition for relief under title 11 of the United States Code; and

(4) The partnership has sufficient assets, and reasonably anticipates having sufficient assets, to pay a potential imputed underpayment with respect to the partnership taxable year that may be determined under subchapter C of chapter 63 of the Internal Revenue Code as amended by the BBA; and

(F) A representation, signed under penalties of perjury, that the individual signing the statement is duly authorized to make the election described in this paragraph (b) and that, to the best of the individual's knowledge and belief, all of the information contained in the statement is true, correct, and complete.

(iii) Notice of Administrative Proceeding. Upon receipt of the election described in this paragraph (b), the IRS will promptly mail a notice of administrative proceeding to the partnership and the partnership representative, as required under section 6231(a)(1) as amended by the BBA. Notwithstanding the preceding sentence, the IRS will not mail the notice of administrative proceeding before the date that is 30 days after receipt of the election described in paragraph (b) of this section.

(c) Election for the purpose of filing an administrative adjustment request (AAR) under section 6227 as amended by the BBA—(1) In general. A partnership that has not been issued a notice of selection for examination as described in paragraph (b)(1) of this section may make an election with respect to a partnership return for an eligible taxable year for the purpose of filing an AAR under section 6227 as amended by the BBA. Once an election under this paragraph (c) is made, all of the amendments made by section 1101 of the BBA, except section 6221(b) as added by the BBA, apply with respect to the partnership taxable year for which such election is made.

(2) Time for making the election. No election under this paragraph (c) may be made before January 1, 2018.

(3) Form and manner of making an election. An election under this paragraph (c) must be made in the manner prescribed by the IRS for that purpose in accordance with applicable regulations, forms and instructions, and other guidance issued by the IRS.

(4) Effect of filing an AAR before January 1, 2018. Except in the case of an election made in accordance with paragraph (b) of this section, an AAR filed on behalf of a partnership before January 1, 2018, is deemed for purposes of paragraph (d)(2) of this section, to be an AAR filed under section 6227(c) (prior to amendment by the BBA) or an amended return of partnership income, as applicable.

(ii) The partnership is deemed to have filed an AAR under section 6227(c) (prior to the amendment by the BBA) in accordance with paragraph (c)(4) of this section, or
