72(t) SEPP

A 72(t) SEPP, short for substantially equal periodic payments under IRC Section 72(t), is the IRS exception that unlocks an IRA or employer plan before 59½ without the 10% additional tax. The account owner commits to annual payments calculated by one of three IRS methods, sized from the account balance and life expectancy. Income tax still applies to every payment; only the penalty is waived.

The commitment is the defining feature: payments must continue for the longer of five years or until age 59½. A 45-year-old runs the schedule at least fourteen and a half years; a 57-year-old runs it five. Modifying or stopping the schedule early reinstates the 10% penalty retroactively on every payment taken, plus interest. The IRS allows a single one-time switch from the fixed methods to the required minimum distribution method, which lowers payments after a market fall.

The mechanics start with one account, one schedule, one method. The balance is converted into a payment stream under one of three methods. The required minimum distribution method divides the balance by a single- or joint-life divisor. The fixed amortization method prices the balance as a level annuity at a reasonable interest rate. The fixed annuitization method uses an annuity factor from an IRS mortality table.

The amortization and annuitization methods produce the same payment every year; the RMD method recalculates annually and produces smaller, flexible payments. A $500,000 IRA at 45 under amortization pays roughly $25,000 a year, penalty-free, but every dollar of it is ordinary income at the owner's bracket. The schedule is locked: the payment does not flex with markets, expenses, or moods, and the money behind it is committed for the duration. The one-time switch to the RMD method is the only relief valve, and it exists precisely because the fixed methods overpay after a crash. Missing a payment, taking an extra distribution, or rolling the account into a structure that breaks the schedule all count as modification, and the IRS retroactively charges 10% plus interest on every payment since the start.

The 72(t) exists for one specific person: the early retiree who needs pre-59½ income from accounts the 10% penalty otherwise locks. It is the difference between retiring at 50 on an investment portfolio and waiting, because a seven-figure balance can fund a $40,000-a-year payment stream a decade and a half before the penalty window closes. It is also the least flexible instrument in the retirement toolbox, which is the price of the exception.

I watched a colleague named Brent (yes, that Brent) start a SEPP at 46, then raid it in year three to cover a boat a dealer was happy to finance. The retroactive bill: the 10% penalty on roughly $75,000 of payments taken, plus interest, landing in one tax year at the 32% bracket. The boat depreciated faster than the paperwork arrived.

The highest-leverage thing most early retirees can do is exhaust the simpler exceptions first: the Rule of 55 for employer plans, Roth basis, and the 457(b) if the employer offered one. Where a SEPP is genuinely needed, price it first with the Rule 72(t) calculator, and model the drawdown it feeds with the retirement drawdown calculator.
