What is a 72(t) Distribution?

A 72(t) distribution, also called Substantially Equal Periodic Payments (SEPP), is a way to withdraw money from an IRA or employer retirement plan before age 59.5 without owing the usual 10% early-withdrawal penalty. In exchange, you commit to taking a fixed series of roughly equal payments, set by an IRS-approved formula, for a defined number of years.

The name comes from Section 72(t) of the Internal Revenue Code (IRC), which carves out this exception to the penalty. It’s one of the few ways to tap an IRA early without being penalized, which makes it a common bridge for people who retire well before 59.5 and need income from money that would otherwise be locked away. The withdrawals are still taxed as ordinary income; only the 10% penalty is avoided.

72(t) Distribution Rules

Once you start a SEPP, you have to keep taking the calculated payments for the longer of five years or until you reach age 59.5. Someone who starts at 50 continues until 59.5, nearly a decade. Someone who starts at 57 continues until 62, because the five-year period is the longer one. Stopping early, changing the amount, or taking an extra withdrawal generally busts the plan and triggers penalties, covered below.

You can set up a 72(t) from a traditional IRA at any age. From an employer plan like a 401(k), you generally have to have separated from service with that employer first, which is why most people run a SEPP from an IRA. Because the payment size depends on the account balance, a common tactic is to split a large IRA into two: you run the SEPP on one, sized to produce the income you need, and leave the other untouched and available for emergencies.

How 72(t) Payments Are Calculated

The IRS recognizes three methods, and your choice sets how large the annual payment is:

• Required minimum distribution method. Divides the account balance by a life-expectancy factor each year. The payment recalculates annually with the balance, so it moves up and down with the account, and it produces the smallest starting payment of the three.
• Fixed amortization method. Amortizes the balance over your life expectancy at a chosen interest rate, producing a level payment that stays the same for the whole term.
• Fixed annuitization method. Divides the balance by an annuity factor drawn from IRS mortality tables and an interest rate, also producing a level payment.

For the two fixed methods, IRS Notice 2022-6 lets you use any interest rate up to the greater of 5% or 120% of the federal mid-term rate for the month you start. A higher rate allows a larger payment, so the rule effectively caps how much you can pull. The RMD method doesn’t use a chosen rate at all.

For example, a 55-year-old with a $500,000 IRA using the fixed amortization method at a 5% rate would take roughly $30,000 a year, held level for the term. The RMD method on the same balance would start lower and shift each year with the account. The exact figure depends on the life-expectancy table, the interest rate, and the account valuation date you choose, which is why most people run the numbers through a SEPP calculator before committing.

One piece of flexibility is built in: you’re allowed a single, one-time switch from either fixed method to the RMD method without busting the plan. People use it when a falling balance makes the fixed payment feel too aggressive.

What Happens If You Modify a 72(t)

This is where 72(t) earns its reputation for rigidity. If you change the payment amount, take an extra distribution, roll the account over, or stop before the required period ends, the IRS treats it as a modification. The 10% penalty you had avoided is applied retroactively to every distribution taken since the SEPP began, plus interest.

That retroactive clawback is why a 72(t) is a commitment rather than a convenience, and why the payment has to work across the entire term before you start. Since that amount interacts with your tax bracket and the rest of your drawdown, it’s worth testing first: you can model an early-retirement income plan in ProjectionLab to see how a 72(t) payment fits alongside your other accounts, what it does to your taxes each year, and how long your savings last.

72(t) vs. the Rule of 55

The Rule of 55 is the other main way to reach retirement money penalty-free before 59.5, and it’s simpler when it applies.

If you’re leaving a job at 55 or later and the money is in that employer’s plan, the Rule of 55 is almost always the better choice: no fixed schedule and no clawback risk. A 72(t) earns its keep when you’re younger than 55, or when your savings sit in an IRA that the Rule of 55 can’t reach.

Frequently Asked Questions

What interest rate can I use for a 72(t)? For the fixed amortization and annuitization methods, IRS Notice 2022-6 allows any rate up to the greater of 5% or 120% of the federal mid-term rate for the month you begin. A higher rate produces a larger payment, so this sets the practical ceiling on how much you can withdraw. The RMD method doesn’t use a chosen rate.

Can I stop a 72(t) distribution early? Not without a cost. You have to continue payments for the longer of five years or until age 59.5. Stopping sooner busts the plan, and the 10% penalty is applied retroactively to every SEPP distribution you’ve taken, plus interest.

Can I set up a 72(t) from a 401(k)? Usually only after you’ve separated from service with that employer. While you’re still working there, most 401(k) plans won’t permit it, so people typically wait until they leave or run the SEPP from an IRA instead.

What happens if I take an extra withdrawal during a 72(t)? Any distribution beyond the calculated amount counts as a modification, which busts the plan and triggers the retroactive penalty and interest. Because a 72(t) is that unforgiving, it’s usually sized carefully or run on only part of your savings.

72(t) vs. the Rule of 55: which is better? If you’re leaving your job at 55 or older and the money is in that employer’s 401(k) or 403(b), the Rule of 55 is simpler and more flexible. Use a 72(t) when you’re under 55 or need to draw from an IRA, accepting its fixed schedule and clawback risk in exchange.
