How RMDs Work

Required Minimum Distributions (RMDs) are mandatory annual withdrawals from tax-deferred retirement accounts. The IRS requires you to begin taking RMDs at a certain age, based on your birth year under the SECURE 2.0 Act:

  • Born 1950 or earlier: RMDs start at age 72
  • Born 1951–1959: RMDs start at age 73
  • Born 1960 or later: RMDs start at age 75

RMD = Prior Year-End Balance ÷ Distribution Period

Your distribution period comes from the IRS Uniform Lifetime Table III, which decreases with age (e.g., 27.4 at age 72, down to 2.0 at age 120). A shorter period means a larger required withdrawal.

Joint Life Table exception: If your sole beneficiary is a spouse more than 10 years younger, you can use IRS Table II instead, which provides a longer distribution period and smaller RMD.

Penalty for missed RMDs: The SECURE 2.0 Act reduced the penalty from 50% to 25% of the shortfall (10% if corrected within two years). Take your RMDs on time.
