72(t) SEPP Calculator 2026: Penalty-Free IRA Access Before Age 59½

If you retired early — in your 50s, or even late 40s — and need income from your IRA or 401(k) before age 59½, Rule 72(t) is the main IRS mechanism for doing that without the 10% early-withdrawal penalty. This calculator compares the two most commonly used methods (RMD and amortization) and shows your required annual payment, total distribution commitment, and duration. You still owe income tax on every distribution — only the 10% penalty is waived.

72(t) SEPP calculator

What is Rule 72(t) / SEPP?

IRC § 72(t)(1) imposes a 10% penalty on distributions from IRAs and 401(k)s taken before age 59½. IRC § 72(t)(2)(A)(iv) creates an exception for "substantially equal periodic payments" (SEPP) — a series of distributions calculated using one of three IRS-approved methods and paid at least annually for a minimum commitment period.

The result: you can access your retirement savings years before 59½ without the 10% penalty, as long as you follow the SEPP rules exactly and don't deviate. You still owe ordinary income tax on every distribution from a traditional IRA or pre-tax 401(k).

The three IRS-approved SEPP calculation methods

1. RMD method (lowest payments, variable)

Annual payment = Account balance ÷ IRS Single Life Expectancy factor for your age (Table I, IRS Pub 590-B)²

This recalculates every year — as your balance changes with market returns and distributions, so does your payment. This flexibility is the method's main advantage: it naturally adjusts to a declining balance. The downside is you cannot predict future payments.

2. Amortization method (higher payments, fixed)

Amortizes your account balance over your life expectancy at an interest rate not exceeding 120% of the applicable federal rate (AFR). Produces a fixed dollar amount for the entire SEPP period.

For May 2026: 120% of the mid-term AFR = 4.58% is the maximum rate.¹ Using a lower rate produces a smaller, more conservative fixed payment. You may use the AFR for the month payments begin or either of the two preceding months.

3. Annuitization method (similar to amortization)

Divides your account balance by an annuity factor from IRS Rev. Proc. 2002-62, mortality tables, at the same maximum interest rate. Produces fixed payments similar to amortization — typically within 3–8% of amortization results. The calculation requires looking up a specific annuity factor from the IRS table; consult a tax professional for this method.³

Duration and the commitment you're making

Once you start a SEPP arrangement, you must continue unmodified until the later of:

• 5 years from the first distribution, or
• Age 59½

Starting SEPP at 55 or older means you're committed past age 59½. Many planners therefore start SEPP earlier (52–54) so the commitment ends closer to 59½, rather than starting at 57 and being locked in until 62.

Account restrictions — what you cannot do

The SEPP "series" applies to a specific IRA or account balance. Once established:

• No new contributions to the SEPP account. Adding money modifies the arrangement.
• No additional withdrawals beyond the scheduled SEPP payment. Taking an extra distribution — for any reason — "busts" the SEPP.
• No rollovers into or out of the SEPP account mid-stream.
• You CAN keep other IRAs separate. You don't have to put all your IRA assets into the SEPP arrangement. Many early retirees carve out just enough — e.g., $400,000 to fund $20,000/year in SEPP payments — and keep remaining IRA funds untouched for later growth.

The one-time switch rule (Notice 2022-6)

Under IRS Notice 2022-6⁴, you may make a one-time switch from the amortization or annuitization method to the RMD method. This is a permanent change — you can't switch back. The main reason to do this: if your account balance has fallen significantly and your fixed amortization payment is consuming the account faster than intended, switching to the RMD method produces a lower (balance-adjusted) payment and extends the account's life.

Alternatives to consider first

Rule of 55 (or 50 for public safety employees)

If you separated from a 401(k) plan in or after the year you turned 55, you can take penalty-free withdrawals from that specific 401(k) — without any SEPP commitment. No rigid payment schedule, no modification restrictions. For public safety employees, the age threshold is 50. Note: this applies to the 401(k) from the employer you just left, not a prior employer's plan or an IRA.⁵

Roth contribution withdrawals (no penalty, no tax)

Direct Roth IRA contributions (not conversions, not earnings) can always be withdrawn tax-free and penalty-free at any age. If you made Roth contributions over the years, you may already have a penalty-free bridge. The ordering rules: contributions come out first, then conversions, then earnings.

Roth conversion ladder

Convert pre-tax IRA funds to Roth IRA each year, then withdraw those conversion amounts five years later penalty-free (the 5-year conversion seasoning rule). This requires 5 years of living expenses from other sources while conversions season, but leaves you with more flexibility than SEPP and also reduces future RMDs. Best suited for early retirees with a multi-year cash runway.

Taxable brokerage account bridge

If you have taxable brokerage investments, draw from those first (at capital gains rates, not ordinary income) and let retirement accounts continue growing. Often the most tax-efficient choice if the taxable account is large enough to bridge to 59½.

Steps to set up a SEPP arrangement

1. Choose the account. Decide how much of your IRA to designate for SEPP. You can split a large IRA into two — one for SEPP, one untouched — using a direct IRA-to-IRA transfer before starting payments.
2. Choose the method and document it. Calculate under all three methods. Most people choose amortization for higher fixed income or RMD for lower, more flexible payments. Document your calculation, the life expectancy table used, the AFR, and the first payment date.
3. Notify your IRA custodian. Set up the scheduled distribution. Make sure they understand no additional distributions should be processed from this account.
4. File IRS Form 5329 if needed. The custodian may code the distribution as an early distribution (Code 1). You report the exception on Form 5329 using Exception Code 02 to claim the SEPP penalty waiver.⁶
5. Stay the course. Don't make any contributions, rollovers, or extra withdrawals from the SEPP account until the required period ends. Mark your calendar for the end date.
