RMDs are the minimum amounts that the IRS requires you to withdraw from traditional, SEP/SARSEP or SIMPLE IRA accounts each year once you turn age 72.
You’re also required to take RMDs from employer plan accounts, e.g., 401(k), 403(b), 457, money purchase and profit-sharing plans. Those distributions generally begin when you turn age 72 or when you retire, whichever is later.
The SECURE Act increased the age when required minimum distributions (RMD) must begin from 70½ to 72, effective for individuals turning 70½ on or after January 1, 2020. If you reached age 70½ before this date, you are still required to take RMDs.
