Notice 2026-27 — This notice specifies updated static mortality tables to be used for defined benefit pension plans under § 430(h)(3)(A) of the Code and section 303(h)(3)(A) of ERISA.

Section 412 of the Code provides minimum funding requirements that generally apply for defined benefit plans. Pursuant to § 412(a)(2), § 430 sets forth the minimum funding requirements that apply to a defined benefit plan (other than a multiemployer plan described in § 414(f) or a CSEC plan described in § 414(y)). Section 430(a) defines the minimum required contribution for such a plan by reference to the plan’s funding target for the plan year. Under § 430(d)(1), a plan’s funding target for a plan year generally is the present value of all benefits accrued or earned under the plan as of the first day of that plan year.

Section 430(h)(3) provides rules regarding the mortality tables that generally are used under § 430. Under § 430(h)(3)(A), except as provided in § 430(h)(3)(C) or (D), the Secretary is to prescribe by regulation mortality tables to be used in determining any present value or making any computation under § 430.¹ Those tables are to be based on the actual experience of pension plans and projected trends in that experience. In accordance with that standard, the Department of the Treasury and the Internal Revenue Service issued § 1.430(h)(3)-1 to provide base mortality tables and mortality improvement rates that apply for valuation dates occurring on or after January 1, 2024.

Section 1.430(h)(3)-1(a)(1) permits the projection of mortality improvement to be applied in either of two ways: through use of generational mortality tables or through use of static mortality tables (available only to small plans described in § 1.430(h)-1(c)(1)(ii)) that are updated annually to reflect expected improvements in mortality. Note 1 to § 1.430(h)(3)-1(c)(1)(iv) states that the static mortality tables for valuation dates occurring in calendar years starting with 2025 will be published in the Internal Revenue Bulletin.

Section 431 provides the minimum funding standards for multiemployer plans that are subject to § 412. Section 431(c)(6)(D)(iv) provides that the Secretary may by regulation prescribe mortality tables to be used in determining current liability for purposes of § 431(c)(6)(B). Section 1.431(c)(6)-1 provides that the same mortality assumptions that apply for purposes of § 430(h)(3)(A) and § 1.430(h)(3)-1(a)(2) are used to determine a multiemployer plan’s current liability for purposes of applying the full-funding rules of § 431(c)(6). For this purpose, either the generational mortality tables or the static mortality tables are permitted to be used without regard to whether the plan is a small plan.

Section 433 provides the minimum funding standards for CSEC plans. Section 433(h)(3)(B)(i) provides that the Secretary may by regulation prescribe mortality tables to be used in determining current liability for purposes of § 433(c)(7)(C). Section 1.433(h)(3)-1(a) provides that the mortality tables described in § 430(h)(3)(A) are to be used to determine current liability under § 433(c)(7)(C). For this purpose, either the generational mortality tables or the static mortality tables are permitted to be used without regard to whether the plan is a small plan.

Section 417(e)(3) generally provides that the present value of certain accelerated forms of benefit under a qualified pension plan (including single-sum distributions) must not be less than the present value of the accrued benefit using applicable interest rates and the applicable mortality table. Section 417(e)(3)(B) defines the term “applicable mortality table” as the mortality table specified for the plan year under § 430(h)(3)(A) (without regard to § 430(h)(3)(C) or (D)), modified as appropriate by the Secretary. Under § 1.417(e)-1(d)(2)(i), the applicable mortality table for a calendar year is the mortality table that is prescribed by the Commissioner in guidance published in the Internal Revenue Bulletin.

Rev. Rul. 2007-67, 2007-2 CB 1047, provides that, except as otherwise stated in future guidance, the applicable mortality table under § 417(e)(3) is a static mortality table set forth in published guidance that is developed based on a fixed blend of 50 percent of the static male combined mortality rates and 50 percent of the static female combined mortality rates used under § 1.430(h)(3)-1. Rev. Rul. 2007-67 also provides that the applicable mortality table for a calendar year applies to distributions with annuity starting dates that occur during stability periods that begin during that calendar year.

STATIC MORTALITY TABLES FOR 2027

The static mortality tables that apply under § 430(h)(3)(A) for valuation dates occurring during 2027 are set forth in the appendix to this notice. The mortality rates in these tables have been developed using the methodology set forth in § 1.430(h)(3)-1(c), the base mortality rates set forth in § 1.430(h)(3)-1(d), and the mortality improvement rates that are incorporated by reference under § 1.430(h)(3)-1(b)(1)(iv)(A).

The static mortality table that applies under § 417(e)(3) for distributions with annuity starting dates occurring during stability periods beginning in 2027 is set forth in the appendix to this notice in the column labeled “Unisex.” The mortality rates in this table are derived from the mortality tables specified under § 430(h)(3)(A) for 2027 in accordance with the procedures set forth in Rev. Rul. 2007-67.
