The tax law requires that you use these actuarial tables to value annuities, life estates, remainders and reversions, with certain exceptions. These actuarial tables do not apply to qualified retirement arrangements.  They also do not apply to limited conditions provided in the regulations at 1.7520-3, 20.7520-3 and 25.7520-3. 

These actuarial tables are revised every 10 years to account for the most recent mortality experience.

Interest Rate

When you use these tables, the law requires that you apply an interest rate equal to:

The “section 7520 rate,” which is 120 percent of the applicable Federal mid-term rate in effect for the month when the valuation date falls, rounded to the nearest 2 tenths of a percent.

For valuations relating to certain charitable transfers: You may instead elect to use the rate in effect for 1 of the 2 months before the valuation date.

Current and Proposed Actuarial Tables

Current and proposed actuarial tables are linked below. For the period from January 1, 2021 to the effective date of final regulations that implement the updated tables, you may rely on either current or proposed tables: 

  • Current tables are derived from mortality experience around the year 2000 (2000CM). They apply to valuation dates starting May 1, 2009 until the date of final regulations implementing the proposed tables.
     

  • Proposed tables are derived from mortality experience around 2010 (2010CM). They are referenced in proposed regulations issued on May 5, 2022.  When updated tables are approved in final regulations, they will also be reflected in the next version of Publications 1457, 1458 and 1459.
