Rule 72(t) / SEPP: Penalty-Free Early Retirement Withdrawals
Rule 72(t) explained: how SEPP lets you withdraw from an IRA or 401(k) before 59 1/2 without the 10% penalty, the three IRS methods, and the risks.

Normally, withdrawing from an IRA or 401(k) before age 59 1/2 triggers a 10% early-withdrawal penalty on top of income tax. Rule 72(t) is the exception: it lets you take substantially equal periodic payments (SEPP) early without that penalty, provided you follow the rules exactly.
The three IRS methods
- Required minimum distribution method — recalculated each year from your balance and life expectancy; the payment moves with the account.
- Amortization method — a fixed annual payment, like a loan schedule, using your balance and an allowed interest rate.
- Annuitization method — a fixed payment derived from an annuity factor; also stays level year to year.
The rules that lock you in
Once you start, the payments must continue for the longer of five years or until you turn 59 1/2 — whichever comes later. You generally cannot change the amount or take extra out during that window. Breaking the schedule, called busting the plan, retroactively applies the 10% penalty to every payment you have taken, plus interest.
Who it suits
SEPP can bridge an early retirement or a gap before other income starts, but it is rigid by design. Because a mistake is expensive, many people split off a separate IRA sized to produce exactly the payment they need, leaving the rest untouched and flexible.
