72(t) Tax Code: SEPP Methods, Modifications, and RMD Switch

A 72(t) SEPP plan lets you pull money from an IRA or a former employer’s retirement plan before age 59½ without paying the 10% early-withdrawal penalty, provided you commit to a schedule of substantially equal periodic payments calculated under one of three IRS methods and stick to it for at least five years or until you turn 59½, whichever comes later. The exception under Section 72(t) waives the 10% surcharge only. Every dollar you draw from a traditional account is still ordinary taxable income in the year you receive it.

Which Accounts You Can Use

IRAs are the usual vehicle because you can start a SEPP from an IRA while you’re still working. The IRS does not require separation from service for IRA-based SEPP distributions. A 401(k) or 403(b) can also anchor a SEPP, but only after you have formally left that employer. If you’re still on the payroll, that plan is off-limits for this purpose.¹

If you’re still employed and need access to money in an old 401(k), a common workaround is to roll that balance into an IRA first and start the SEPP from the IRA.

The Three Calculation Methods

The IRS recognizes three ways to determine your annual SEPP payment, all laid out in Notice 2022-6.²

Required minimum distribution (RMD) method. Divide the account balance by a life expectancy factor from an IRS table. You recalculate every year, so the payment moves with the account value. It produces the smallest starting payment of the three but adjusts down if your investments fall.
Fixed amortization method. Spread the balance over your life expectancy using a chosen interest rate. The result is a level annual payment that stays the same each year. It typically produces a larger payout than the RMD method.
Fixed annuitization method. Divide the balance by an annuity factor built from a mortality table and interest rate. Like fixed amortization, this locks in a constant annual amount, though the underlying math can produce a slightly different figure.

Every method starts with an account balance. For the RMD method you generally use the prior year-end balance. For the two fixed methods the IRS allows any reasonable valuation based on the facts, such as your last year-end statement adjusted for activity since then.¹

The fixed methods also require an interest rate. You may 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.² Treasury publishes these rates monthly.³ A higher rate produces a larger payment, so which month you start in can affect your cash flow for years.

The life expectancy factor comes from an IRS table. The Uniform Lifetime Table applies to most people. If your sole beneficiary is a spouse more than ten years younger, you use the Joint Life and Last Survivor Table, which lengthens life expectancy and lowers the annual payment.⁴

How Long the Payments Must Continue

Once you begin, you must keep taking distributions until the later of two dates: five full years after your first payment, or the date you turn 59½.¹ Start at 50 and you continue until 59½. Start at 57 and the five-year rule controls, so you continue until 62. The younger you start, the longer the commitment and the deeper the drawdown.

Death and total disability are the only events that let a SEPP stop early without penalty.⁵

What Counts as a Modification

The IRS defines modification broadly, and any of these breaks the plan:

Taking more or less than the calculated amount in a given year, even by a small margin.
Adding money to the SEPP account through contributions, rollovers, or transfers after the plan starts.
Taking any non-SEPP distribution from the account, so no extra pulls outside the schedule.
Switching calculation methods, other than the one-time switch described below.

The recapture tax is 10% of every distribution taken since the plan began, plus interest running from the year each distribution was received through the year of the modification.¹ On a plan several years old, the combined bill can be substantial. Most breaks are accidental: an automatic rebalancing that moves money into the account, a hardship withdrawal the account holder forgot came from the SEPP account, or a custodian error.

The One-Time Switch to RMD

If you started with fixed amortization or fixed annuitization and your account value drops sharply, the locked-in payment can drain the balance faster than expected. The IRS allows one irrevocable switch to the RMD method. That switch is not a modification and does not trigger the recapture tax.¹ After the change, payments fluctuate with the account balance. You cannot switch back, and you cannot switch to any other method later.

Sizing the Payment With Multiple Accounts

The IRS requires each SEPP to be calculated from a single account, and you cannot combine balances across accounts to hit a target number.¹ That rule cuts both ways, and it’s the main planning lever people use to control the payment size.

Say you have a $600,000 IRA and the SEPP formula on the full balance produces more income than you need. Split the IRA in two before starting. Roll $250,000 into one IRA, keep $350,000 in the other, and start the SEPP only on the $250,000 account. The other IRA is untouched and not bound by the SEPP rules. Each SEPP operates independently, and each account’s payments must come from that specific account.

Payment Frequency

The annual amount can be paid monthly, quarterly, or on any schedule you choose, as long as the total received during the year matches the calculated figure.¹ Most people take monthly distributions to replace a paycheck. A single annual lump sum is not required.

Tax Reporting

Your custodian issues a Form 1099-R for each year of SEPP payments. Check box 7. Distribution code 2 signals that the early distribution qualifies for a penalty exception.⁶ If the custodian uses code 1 instead (early distribution, no known exception), you’ll need to file Form 5329 to claim the SEPP exception yourself so the penalty is not assessed automatically.⁷

The SEPP exception waives the 10% surcharge only. Every distribution from a traditional account is still included in your gross income for the year and taxed at your ordinary rate.

Before You Commit

Section 72(t)(2) lists many other exceptions to the 10% penalty that don’t require a multi-year commitment: disability, unreimbursed medical expenses above 7.5% of AGI, qualified higher-education expenses from an IRA, up to $10,000 for a first-time home purchase from an IRA, health insurance premiums while unemployed, distributions to an alternate payee under a QDRO, separation from service in or after the year you turn 55 (or 50 for certain public safety employees), up to $5,000 for a qualified birth or adoption, up to $22,000 for federally declared disaster losses, up to $10,000 for domestic abuse victims, and $1,000 per year for a personal emergency.⁸ If one of those fits your situation, you can take a single withdrawal without locking into a SEPP schedule. SEPP is the option when none of the narrower exceptions apply and you need ongoing access to retirement funds before 59½.
