Substantially Equal Periodic Payments: SEPP and 72(t) Rules

Substantially equal periodic payments, often called a SEPP plan or a 72(t) plan, let you pull money from a retirement account before age 59½ without the usual 10% early-withdrawal penalty. The exception is written into IRC Section 72(t)(2)(A)(iv), which waives the penalty as long as your distributions come out in a structured series calculated around your life expectancy.¹ The catch is commitment. Once you start, you’re locked into the schedule for years, and even small deviations trigger back-penalties on every distribution you’ve already taken.

How the Penalty Exception Works

Under Section 72(t), early distributions from retirement accounts normally carry a 10% additional tax on top of regular income tax. SEPP carves a narrow path around that penalty by requiring you to take distributions that are part of a series calculated over your life expectancy, or the joint life expectancies of you and a beneficiary.² Payments have to occur at least once a year and follow one of three IRS-approved calculation methods. You cannot simply withdraw whatever amount feels right in a given year.

“Substantially equal” means the annual amount is set by the calculation method you choose and then stays there, or follows the specific recalculation rules of the RMD method, for the full duration of the plan. The distributions are still ordinary income for tax purposes. SEPP removes the 10% penalty; it does not remove the tax bill.

Which Accounts You Can Use

Traditional IRAs are the most common vehicle because they offer the most flexibility. You control the account, choose the custodian, and don’t need anyone’s permission to begin distributions. SEP-IRAs and SIMPLE IRAs also qualify.¹

Employer plans like 401(k)s and 403(b)s are eligible too, but with an extra requirement: you must have separated from service with the employer maintaining the plan before payments can begin.³ You cannot start a SEPP from a 401(k) while still working for that company. For this reason, many people roll their employer plan balance into a Traditional IRA before setting up a SEPP.

Roth IRAs are a special case. You can always pull your direct Roth contributions tax- and penalty-free at any age, so SEPP only becomes relevant for the earnings portion of a Roth. Because the Roth ordering rules treat contributions as coming out first, you would typically need to have already exhausted your contribution basis before a SEPP would tap earnings. Most SEPP plans are built on Traditional IRAs, where every dollar withdrawn is otherwise exposed to the penalty.

The Three Calculation Methods

The IRS allows three ways to calculate your annual SEPP amount. IRS Notice 2022-6 is the current governing guidance.³ Each method produces a different annual payout, so the choice drives how much cash you get and how much flexibility you keep.

Required Minimum Distribution Method

The RMD method divides your account balance by a life expectancy factor each year. Because both the balance and the factor update annually, the payment changes every year. In a rising market, distributions go up; in a downturn, they shrink. This method usually produces the smallest initial payout of the three, but it’s the most forgiving. The annual recalculation lets the plan absorb market swings without triggering a modification.

Fixed Amortization Method

Amortization works like a mortgage in reverse. You calculate a level annual payment using your account balance, a chosen interest rate, and a life expectancy factor. Once set, that dollar amount stays the same every year for the life of the plan.³ The fixed amount generally runs higher than the RMD result, which helps if you want a predictable income stream. The tradeoff is rigidity: if the market drops sharply, the same distribution keeps coming out and can erode the account faster than expected.

Fixed Annuitization Method

The annuitization method divides your account balance by an annuity factor built from mortality data, producing a fixed annual payment. Like amortization, the amount is set once and stays constant. The two fixed methods often produce similar figures, though the exact amounts differ because they use different actuarial approaches. Neither adjusts for market performance, so both carry the same risk of accelerated depletion in a prolonged downturn.

Interest Rate, Balance, and Life Expectancy Inputs

The fixed amortization and fixed annuitization methods both require an interest rate assumption. Under 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 distribution.⁴ With current mid-term rates below 5%, the 5% floor is the binding cap. A higher assumed rate produces a bigger annual distribution but drains the account faster; a lower rate produces a smaller payment and preserves more of the balance.

For the account balance, Notice 2022-6 lets you use a value determined on any date from December 31 of the prior year through the date of your first distribution.⁴ That window gives you room to choose a valuation date reflecting a balance you’re comfortable building the plan around.

You also pick a life expectancy table. The IRS permits the Uniform Lifetime Table in Appendix A of Notice 2022-6, the Single Life Table, or the Joint and Last Survivor Table.³ These are not the same tables used for regular required minimum distributions after age 73. If you have a designated beneficiary and want to spread payments over both lifetimes, the Joint and Last Survivor Table generally produces a smaller annual payment because the combined life expectancy is longer.

How Long You’re Locked In

This is where SEPP plans get genuinely risky. Once payments start, you must continue them until the later of two milestones: five full years from the date of the first payment, or the date you turn 59½.² Start at 50, and you’re committed for nine and a half years, until you reach 59½. Start at 57, and you’re committed for five years, until age 62, because five years extends beyond 59½.

Modifying the payment series before that window closes triggers a recapture tax. The IRS goes back and applies the 10% early-withdrawal penalty to every distribution taken since the plan began, plus interest on each year’s unpaid penalty calculated from the year the distribution was originally taken.² On a plan running several years with sizable distributions, the combined bill can be substantial.

What Counts as a Modification

The IRS defines a modification as taking an annual amount more or less than the amount your chosen method requires.³ That includes skipping a payment, taking an extra distribution, or rolling additional money into the SEPP account. Even a partial transfer out of the account changes the balance and disrupts the calculation.

Some events don’t count. Death and disability are explicitly excluded from the recapture rule in the statute itself.² Ordinary changes in account value from investment performance are also not modifications. If the account is completely depleted to zero through a final annual distribution, the IRS does not treat that as a modification either.³

The One-Time Switch to RMD

If you started with the fixed amortization or fixed annuitization method and circumstances change, you’re allowed one switch to the RMD method. This switch can happen in any year after the year you began distributions, and the IRS does not treat it as a modification.⁵ Once you switch to RMD, that’s it; you use RMD for all remaining years. Any further change is a modification and triggers the full recapture.

The switch is essentially an escape valve. The fixed methods lock you into a dollar amount regardless of what happens to the market or your balance. If those payments become unsustainable, moving to RMD lets the distribution float with the actual balance. Payments will likely drop, since RMD typically produces smaller distributions, but the account survives longer.

Split the Account Before You Start

Each SEPP plan is tied to a single account. You cannot combine the balances of multiple IRAs to calculate one larger SEPP distribution.³ If you want SEPP plans on more than one account, you set up a separate plan for each, and each plan’s distributions must come from its own account.

Once a SEPP is running on an account, you cannot make any contributions to that account or take any distributions beyond the scheduled SEPP payments.³ That is why experienced planners almost always recommend splitting your IRA before starting. Move the amount you want the SEPP based on into a separate IRA. Keep the rest in another account you can access freely. If you need extra cash for an emergency later, you can withdraw from the non-SEPP account without touching the plan. Pulling even a single extra dollar from the SEPP account is a modification.

Setting Up the Plan With Your Custodian

The first step is deciding how much annual income you actually need, then working backward to figure out which method, interest rate, and life table produce that amount from your available balance. You have real choices: the interest rate (up to 5% or 120% of the mid-term rate, whichever is higher), the life expectancy table, and the method itself all move the final number.

Once the inputs are set, notify the custodian holding the account. You will complete paperwork specifying the distribution schedule, and the forms should reflect a 72(t) exception so the custodian codes the distributions correctly. Ideally, the custodian uses Distribution Code 2 on Form 1099-R, which tells the IRS the early-withdrawal penalty does not apply.⁶ If the custodian defaults to Code 1 (early distribution, no known exception), you will need to file Form 5329 with your tax return to claim the SEPP exemption yourself.

In the first year, you do not prorate for a partial year. The IRS expects total payments during that calendar year to equal the annual amount your method produces. Take it as one lump payment or split it into monthly or quarterly installments, as long as the year’s installments add up to the correct annual figure.³ The plan officially begins on the date of your first payment, which should fall within the calendar year used for your initial balance.

Mistakes That Trigger the Recapture Penalty

The most expensive errors tend to be the simplest. Taking an extra distribution to cover an unexpected expense, skipping a payment in a year you didn’t need the money, or accidentally depositing a rollover into the SEPP account will void the plan retroactively. The recapture isn’t just 10% on the offending transaction. It reaches back to every distribution taken since the plan began, plus interest on each year’s penalty.

Failing to segregate the SEPP account from your other retirement assets is probably the single most preventable mistake. If all your IRA money sits in one account and you set up a SEPP on the full balance, you have zero flexibility. Every withdrawal beyond the calculated amount is a modification. Splitting the IRA before starting costs nothing and gives you a separate pot you can touch without consequences.

Calculation errors at the outset compound over time. Using the wrong life expectancy table, selecting an interest rate above the permitted maximum, or basing the first payment on a balance from a date outside the allowed window can all render the plan invalid from day one. Getting the math right upfront, and documenting every input, is the single most important thing you can do to protect the plan over its multi-year life.
