How it works
Normally withdrawing from an IRA before 59.5 triggers a 10% penalty. Rule 72(t) waives it if you commit to Substantially Equal Periodic Payments (SEPP) — a fixed withdrawal schedule you must follow for at least 5 years or until you turn 59.5, whichever is longer. This uses the required-minimum-distribution method, one of three IRS-approved ways to calculate the payment, dividing your balance by a life-expectancy factor. Breaking the schedule early retroactively triggers penalties on everything you've withdrawn, so this is a serious, hard-to-reverse commitment.
