Notice 2024-42

Section 412 of the Code provides minimum funding requirements that generally apply for defined benefit plans. Section 412(a)(2) provides that § 430 sets forth the minimum funding requirements that apply to defined benefit plans that are not multiemployer plans or CSEC plans. 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. Those tables are to be based on the actual experience of pension plans and projected trends in that experience. Section 430(h)(3)(B) requires the Secretary to revise any table in effect under § 430(h)(3)(A) at least every 10 years to reflect the actual experience of pension plans and projected trends in that experience. Pursuant to that instruction, on October 20, 2023, the Department of the Treasury and the Internal Revenue Service issued TD 9983, 88 FR 72357, which amends the regulations to provide updated base mortality tables and mortality improvement rates that apply for valuation dates occurring on or after January 1, 2024.

Section 430(h)(3)(C) provides that, upon request by a plan sponsor and approval by the Secretary, substitute mortality tables that meet the applicable requirements may be used in lieu of the standard mortality tables provided under § 430(h)(3)(A). Section 430(h)(3)(D) provides for the use of separate mortality tables with respect to certain individuals who are entitled to benefits on account of disability.

Section 1.430(h)(3)-1 provides rules regarding the mortality tables used under § 430(h)(3)(A) for valuation dates occurring on or after January 1, 2024. The mortality tables used under § 430(h)(3)(A) are based on the tables in the Pri-2012 Private Retirement Plans Mortality Tables Report,¹ adjusted for mortality improvement. Section 1.430(h)(3)-1(d) sets forth base mortality tables with a base year of 2012.

Section 1.430(h)(3)-1(a)(1) permits plan sponsors to apply the projection of mortality improvement 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. Section 1.430(h)(3)-1(b)(1)(iii)(A) provides that, for valuation dates occurring in years after January 1, 2024, the mortality improvement rates used to develop these mortality tables are the 2024 Adjusted Scale MP-2021 Rates. These rates, which are incorporated by reference under § 1.430(h)(3)-1(b)(1)(iv)(A), are available at http://www.irs.gov/retirement-plans/pension-plan-mortality-tables. In addition, Note 1 to § 1.430(h)(3)-1(c)(1)(iv) states that the static mortality tables for valuation dates occurring in later calendar years will be published in the Internal Revenue Bulletin.

Section 431 provides the minimum funding standards for multiemployer plans described in § 414(f) 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 described in § 414(y). 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.
