Who takes an RMD at 88
Turning 88 in 2026 means you were born in 1938. Your RMDs started at 70½ under the rules before the SECURE Act. Anyone born in 1960 or later starts at 75 instead, so a first RMD at 75 is due from 2035. Traditional, SEP and SIMPLE IRAs, 401(k), 403(b) and 457(b) plans all count. Roth IRAs, and since 2024 Roth 401(k)s, need none while you are alive. Missing one costs a 25% excise tax on the shortfall, cut to 10% if you correct it in time.
