How Does a 72(t) Work? SEPP Methods, Rules, and Payments

A 72(t) works by letting you pull money from a retirement account before age 59½ without the 10% early-withdrawal penalty, as long as you take a series of substantially equal periodic payments (SEPPs) calculated under one of three IRS-approved methods and keep those payments running for at least five years or until you turn 59½, whichever comes later.¹ Regular income tax still applies to every dollar you withdraw. The only thing 72(t) removes is the extra 10% penalty, and it removes it only if you follow the schedule exactly. Miss a step and the IRS claws back the penalty on every payment you’ve already taken, with interest.

Which Accounts You Can Use

Traditional IRAs and SEP IRAs are the cleanest fit. You can start a SEPP from either one whether or not you’re still working. Employer plans like 401(k)s and 403(b)s qualify too, but only after you’ve separated from the employer that sponsors the plan.¹

That separation rule is why many people roll an employer plan into a traditional IRA first. Once the money lands in the IRA, the separation requirement no longer applies, and payments can start whether you’re working elsewhere or not at all. Complete the rollover before the first payment, and treat the receiving IRA as a standalone account from that point forward.

A couple of boundaries are worth stating up front. Roth IRAs technically qualify, but a SEPP rarely makes sense for one because Roth contributions can already come out tax- and penalty-free at any time. Inherited IRAs don’t need a SEPP at all; distributions to a beneficiary after the original owner’s death are already exempt from the 10% penalty under a separate provision.²

The Three Inputs Behind Every Calculation

Three numbers drive the math: your account balance, a life expectancy factor, and (for two of the three methods) an interest rate.

The balance comes from a reasonable, consistent valuation date, typically a recent month-end or year-end statement. The IRS doesn’t mandate a specific date, but the balance you pick locks into the calculation for the fixed methods.

The life expectancy factor comes from IRS tables: the Single Life table, the Uniform Lifetime table, or the Joint Life and Last Survivor table. Which table you use depends on whether the calculation is based on your life alone or jointly with a beneficiary. Single Life is the most common choice.¹

The interest rate matters only for the fixed amortization and fixed annuitization methods. Under IRS Notice 2022-6, you can use any rate up to the greater of 5% or 120% of the federal mid-term rate for either of the two months before your first payment.³ The 5% floor is doing real work right now. As of early 2026, 120% of the federal mid-term rate is below 5%, so most people starting a SEPP can use the 5% floor and get a meaningfully larger payment than the mid-term rate alone would produce.⁴

The Three Ways to Calculate Your Payment

Each IRS-approved method produces a different dollar amount from the same account. The method you pick shapes your cash flow for the entire commitment period.

Required Minimum Distribution Method

The RMD method divides your account balance by the life expectancy factor. Both numbers get recalculated every year, so the payment moves with the account.¹ Account loses value, payment shrinks. Account grows, payment rises. This method generally produces the smallest initial payment of the three, which suits people who want to preserve the account and only need modest early access.

Fixed Amortization Method

Fixed amortization calculates the level annual payment that would deplete the account over your life expectancy at your chosen interest rate. Once calculated, the payment stays the same every year for the life of the plan.¹ This is the method most people pick when they need a predictable income figure.

Fixed Annuitization Method

Fixed annuitization divides your balance by an annuity factor built from IRS mortality tables and your chosen interest rate. Like amortization, the payment is level.¹ The mortality assumptions differ slightly from amortization, so the two methods produce slightly different payments from identical inputs. Usually the gap is small, and the choice comes down to which figure fits your budget better.

How Long You’re Locked In

Payments must continue until the later of two dates: five full years after the first payment, or the day you turn 59½.¹ Whichever falls second is your finish line.

Start at 52 and you’re locked in until 59½, roughly seven and a half years. Start at 58 and the five-year rule controls, running you to 63. Starting in the mid-50s tends to produce the shortest total commitment because both conditions land near the same date.

Once you clear both requirements, the SEPP is done. Stop the payments, change them, take lump sums, whatever fits. The account reverts to normal withdrawal rules, and you’re past 59½ anyway. No paperwork is needed to end the plan; you tell the custodian to stop or adjust the distributions.

What Breaks the Plan

This is where most 72(t) plans fail. A “modification” is any change to the payment series outside a narrow set of exceptions, and the consequence is retroactive: the IRS imposes the 10% penalty on every distribution taken under the plan, plus interest running from each year’s original due date.¹ Six years into the plan, that’s six years of penalties and compounded interest hitting one return.

Things that count as a modification:

Taking more or less than the calculated annual amount, even by a small margin.
Adding money to the SEPP account through contributions, rollovers, or transfers.¹
Taking any extra withdrawal from the SEPP account beyond the scheduled payment.
Switching methods, other than the one-time switch to RMD described below.

Three situations do not count as modifications even if they change or halt payments: the account holder’s death, the account holder becoming permanently disabled, or a distribution to a qualified public safety employee under Section 72(t)(10).¹ Outside those, treat the schedule as fixed.

The One-Time Switch to RMD

If you start with fixed amortization or fixed annuitization and find the payments larger than you need, the IRS allows one escape valve. You can switch to the RMD method once during the plan, and that single change is not treated as a modification.³ Because the RMD method usually yields lower payments, the switch can drop your annual distribution meaningfully.

In the switch year, you recalculate using the December 31 balance from the prior year divided by your single life expectancy factor for your current age.¹ From then on you recalculate annually under the RMD method for every remaining year of the plan. It’s a one-way door; any further change to the method triggers full recapture.³

Splitting an IRA to Size the Payment

Each SEPP applies to one specific account. You can’t combine multiple IRAs to run a single calculation, and you can’t draw the total from a different account.¹

That single-account rule creates a planning opening. If your IRA is larger than what you actually need to draw from, split it into two IRAs before starting. Run the SEPP on one account and leave the other alone. Because the SEPP account’s balance is what drives the payment calculation, controlling that balance controls your annual distribution. The untouched IRA stays under normal rules and you’re not locked into any schedule on it.

The split has to happen before the first payment. Once a SEPP is running, no money can move into or out of the account outside the scheduled payments, and violating that rule is itself a modification.¹

How the Payments Get Reported

You can take SEPP distributions monthly, quarterly, or annually. The frequency is yours to choose with your custodian, provided the calendar-year total equals the annual amount your calculation produced.¹

At tax time your custodian issues Form 1099-R. Ideally Box 7 carries distribution code 2, “early distribution, exception applies,” which tells the IRS no 10% penalty is owed.⁵ Not every custodian codes it correctly. Some issue code 1, which flags the payment as a normal early withdrawal subject to the penalty.

If your 1099-R comes back with code 1, file Form 5329 with your tax return to claim the SEPP exception yourself.⁶ Filing the form overrides the incorrect code. Check the 1099-R each year rather than assume the custodian got it right; correct reporting is your responsibility, and an uncorrected code 1 generates an automatic penalty notice that you’ll then have to fight.
