The Internal Revenue Service has issued final, temporary and draft regulations concerning the mortality tables used in valuing annuities, interests for life or terms of years, and remainder interests.

The IRS is shifting to use of data from the 2000 census and Life Table 2000CM, officials write in a preamble to the final and temporary regulations.

The IRS is developing several actuarial valuations publication updates that will contain a complete set of actuarial tables that include factors not contained in the temporary regulations released today, officials report.

The upcoming publications will, for example, provide annuity and life interest factors, officials write.

The text of the draft regulations associated with the final and temporary regulations is available here.
