(a) Definition of life insurance reserves. Except as provided in section 816(h), a reserve that meets the requirements of section 816(b)(1) and (2) will not be disqualified as a life insurance reserve solely because the method used to compute the reserve takes into account other factors, provided that the method used to compute the reserve is a tax reserve method as defined in section 807(d)(3) and that such reserve is not an asset adequacy reserve as described in § 1.807-1(b).

(b) Applicability date. The section applies to taxable years beginning after October 13, 2020.

However, a taxpayer may choose to apply the rules of this section for a taxable year beginning after December 31, 2017, the effective date of the revision of section 807 by Public Law 115-97, and on or before October 13, 2020, provided the taxpayer consistently applies the rules of this section to that taxable year and all subsequent taxable years. See section 7805(b)(7).
