IRS issues updated mortality improvement rates and static mortality tables for 2019

The IRS has provided the updated mortality improvement rates and static mortality tables to be used under Code Sec. 430(h)(3)(A). These rates are used to calculate the funding target and other items for valuation dates occurring during calendar year 2019. Also included are modified “unisex” mortality tables for use in determining minimum present value under Code Sec. 417(e)(3) for distributions with annuity starting dates that occur during stability periods beginning in calendar year 2019.

Mortality improvement rates

In October 2017, the IRS issued final regulations that revise the mortality tables used under Code Sec. 430(h)(3)(A) for plan years beginning on or after January 1, 2018. The mortality tables used under Code Sec. 430(h)(3)(A) are based on the tables in the RP-2014 Mortality Tables Report, adjusted for mortality improvement.
The mortality improvement rates for valuation dates occurring during 2019 are the mortality improvement rates in the Mortality Improvement Scale MP-2017 Report (issued by the Retirement Plans Experience Committee (RPEC) of the Society of Actuaries and available at http://www.soa.org/Files/Research/Exp-Study/mortality-improvement-scale-mp-2017.pdf).

Multiemployer plans

The same mortality assumptions that apply for purposes of Code Sec. 430(h)(3)(A) and IRS Reg. §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 Code Sec. 431(c)(6). For this purpose, a multiemployer plan is permitted to apply either the annually adjusted static mortality tables or generational mortality tables.

Cooperative and small employer charity plans

The IRS notes that, under Code Sec. 433(h)(3)(B)(i), regulations may be issued to prescribe mortality tables for cooperative and small employer charity (CSEC) plans to be used in determining current liability for purposes of Code Sec. 433(c)(7)(C). IRS Reg. Sec. 1.433(h)(3)-1(a) provides that the mortality tables described in Code Sec. 430(h)(3)(A) are to be used to determine current liability under Code Sec. 433(c)(7)(C).
