Actuarial tables

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 situations indicated in the regulations at sections 1.7520-3, 20.7520-3 and 25.7520-3.

These actuarial tables are revised approximately 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 either of the two months before the valuation date.

Prior and current actuarial tables

Prior and current actuarial tables are linked below. For the period from May 1, 2019, to June 1, 2023, you may rely on either the prior or current tables.

However, with respect to each individual transaction and with respect to all transfers occurring on the same valuation date, you must be consistent in using the same mortality basis to value each interest (annuity, income, remainder, partial, etc.) in the same property.
