(f) Special participation rules—(1) In general.

(2) Disclosure safe harbor for Owners. An Owner who, solely by reason of the Owner's direct or indirect ownership interest in an Insured, has participated in the transaction of interest described in this section will not be required to disclose participation in the transaction under section 6011(a), notwithstanding § 1.6011-4(c)(3), if the Owner receives acknowledgment, in writing or electronically, from the Insured that the Insured has or will comply with Insured's separate disclosure obligation under § 1.6011-4 with respect to the transaction and the Insured discloses the transaction in a timely manner. The acknowledgment can be a copy of the Form 8886, Reportable Transaction Disclosure Statement (or successor form), filed (or to be filed) by the Insured and must be received by the Owner prior to the time set forth in § 1.6011-4(e) in which the Owner would otherwise be required to provide disclosure.

(3) Disclosure safe harbor for taxpayers in transactions with revoked section 831(b) elections. If the Captive has revoked its section 831(b) election, taxpayers who participated in the transaction of interest with respect to that Captive, including any Insureds, Owners, and Intermediaries, will not be considered participants in the transaction under section 6011(a), notwithstanding § 1.6011-4(c)(3), for any taxable year in which the section 831(b) revocation is effective, provided that a successor Captive has not been established as described in paragraph (b)(2)(iii) of this section (referencing § 1.6011-10(b)(2)(iii) and (iv)).

(g) Disclosure requirements. Participants must provide the information required under § 1.6011-4(d) and the Instructions to Form 8886 (or successor form).

A Captive and an Insured must also provide the information required in § 1.6011-10(g)(2) and (3), respectively.

(h) Applicability date—(1) In general. This section identifies transactions that are the same as, or Substantially Similar to, the transaction identified in paragraph (a) of this section as transactions of interest for purposes of § 1.6011-4(b)(6) effective January 14, 2025, except as otherwise provided in this paragraph (h)(1). If, on or before the date prescribed for filing disclosure statements with the Office of Tax Shelter Analysis under § 1.6011-4(e), the Captive involved in the transaction has requested the consent of the Secretary to revoke its section 831(b) election, the transaction is not identified as a transaction of interest for purposes of this section and § 1.6011-4(b)(6) for participants with respect to that Captive for taxable years ending before January 1, 2026.

(2) Obligations of participants with respect to prior periods. Pursuant to § 1.6011-4(d) and (e), taxpayers who have filed a tax return (including an amended return) reflecting their participation in transactions described in paragraph (a) of this section prior to January 14, 2025, must disclose the transactions as required by § 1.6011-4(d) and (e) provided that the period of limitations for assessment of tax (as determined under section 6501 of the Code, including section 6501(c)) for any taxable year in which the taxpayer participated has not ended on or before January 14, 2025, except as otherwise provided in this paragraph (h)(2). Taxpayers who have finalized a settlement agreement with the Internal Revenue Service with respect to the transaction, in examination or litigation, will be treated as having made the disclosure for years subject to that agreement. Taxpayers who have filed a disclosure statement regarding their participation in the transaction with the Office of Tax Shelter Analysis pursuant to Notice 2016-66, 2016-47 I.R.B. 745, will be treated as having made the disclosure pursuant to the final regulations for the taxable years for which the taxpayer filed returns before January 14, 2025. If a taxpayer described in the preceding sentence participates in the Micro-captive Transaction of Interest in a taxable year for which the taxpayer files a return on or after January 14, 2025, the taxpayer must file a disclosure statement with the Office of Tax Shelter Analysis at the same time the taxpayer files their return for the first such taxable year.

(3) Obligations of material advisors with respect to prior periods. Material advisors defined in § 301.6111-3(b) of this chapter who have previously made a tax statement with respect to a transaction described in paragraph (a) of this section have disclosure and list maintenance obligations as described in §§ 301.6111-3 and 301.6112-1 of this chapter, respectively. Notwithstanding § 301.6111-3(b)(4)(i) and (iii) of this chapter, material advisors are required to disclose only if they have made a tax statement on or after the date that is six years before January 14, 2025. Material advisors that are uncertain whether the transaction they are required to disclose should be reported under this section or § 1.6011-10 should disclose under § 1.6011-10 and will not be required to disclose a second time if it is later determined that the transaction should have been disclosed under this section.
