Internal Revenue Service has updated its actuarial tables for RMDs
IRS updates these every year, and the new ones are built into the next version of PRC.
I did a little more research on this, and in fact this is the first update since 2002: In November 2020, the IRS issued new life expectancy tables. These new tables are effective January 1, 2022. This was the first change in the RMD tables since 2002... - https://braggfinancial.com/new-rmd-tables-in-2022/ and https://www.oppenheimer.com/poindextergroup/financial-newsletters/2022/new-rmd-life-expectancy-tables-for-2022.pdf
@smatthew51 I assume 2022 PRC has these new table values??
@giovanelli766 Yes, the new tables are included in PRC2022.
