72(t) SEPP Calculator — Penalty-Free Early Retirement Withdrawals
Compare all three IRS-approved SEPP methods side by side. Model the Notice 2022-6 max(5%, 120% AFR) rate cap, your exact duration lock, and the retroactive-penalty cost of busting the schedule.
How much can I withdraw penalty-free before 59½ using rule 72(t)?
On a $1,000,000 account at age 50 using a 5.00% rate, the three IRS-approved SEPP methods produce: RMD $27,624/yr, fixed amortization $60,312/yr, fixed annuitization $59,307/yr. Payments must continue until July 1, 2035.
- Rate cap: greater of 5% or 120% mid-term AFR (Notice 2022-6). Your legal max is 5.00%.
- Single-life factor at age 50: 36.2 (Pub 590-B, post-2022).
- Break the schedule and the 10% penalty applies RETROACTIVELY to every SEPP distribution taken before age 59½ — plus interest.
- One-time switch to the RMD method is permitted from either fixed method (Notice 2022-6 §3).

The Bust Warning
Miss a payment, take an extra dollar, or roll the account before your lock ends and the IRS applies the 10% early-withdrawal penalty RETROACTIVELY to every SEPP distribution you took before age 59½ — plus interest from each year's due date. Payments made at or after 59½ are not recaptured. The table below shows what a bust would cost at your amortization payment.
| Years in | Cumulative paid | 10% recapture on pre-59½ payments (plus interest) |
|---|---|---|
| Year 1 | $60,312 | $6,031 |
| Year 3 | $180,937 | $18,094 |
| Year 5 | $301,561 | $30,156 |
| Year 9 | $542,810 | $54,281 |
Plus IRC §6621 interest running from each year's April 15 due date. In year-5 territory the interest alone can add another 15-25% on top of the penalty.

Who should consider a 72(t) SEPP?
72(t) SEPP is for people who need steady income from a pre-tax IRA before age 59½ and want to avoid the 10% early-withdrawal penalty. Classic use cases: early retirees living on portfolio income, a bridge until Social Security or a pension turns on, or someone in a low tax year who wants to draw down a Traditional IRA without penalty.
It's not the only option. A Roth conversion ladder lets you convert Traditional dollars to Roth today, wait 5 years, then withdraw the converted principal penalty-free — with no rigid annual payment lock. And if you're still working, use the Retirement Contribution calculator to size current-year contributions before you commit to a SEPP.
SEPP vs Roth ladder vs Rule of 55
| Strategy | Age requirement | Account types | Flexibility | Main risk |
|---|---|---|---|---|
| 72(t) SEPP | Any age < 59½ | IRAs (cleanest); some workplace plans | Locked — later of 5yr / 59½ | Retroactive 10% penalty if busted |
| Roth conversion ladder | Any age | Traditional IRA → Roth IRA | Flexible — no annual lock | 5-year clock per conversion; tax due on conversion |
| Rule of 55 | Separation in / after the year you turn 55 | Workplace plan ONLY (401(k)/403(b)) | Ad hoc withdrawals allowed | Doesn't work for IRAs; plan must permit |
Account-splitting strategy
Nothing in Rev. Rul. 2002-62 requires you to run a SEPP on ALL your retirement dollars — the plan is tied to a specific account balance. A common tactic: split a large IRA into two before starting. Run the SEPP on IRA #1 (sized to produce exactly the payment you need), and keep IRA #2 completely flexible for emergencies, one-off withdrawals after 59½, or Roth conversions. This dramatically reduces the risk of accidentally busting the plan by needing more cash than the schedule allows.
How to report on your return
- Best case: your custodian reports the distribution on Form 1099-R with distribution code 2 (early distribution, exception applies). Nothing else required.
- Fallback: if the 1099-R comes with code 1 (early distribution, no known exception), file Form 5329 and claim exception code 02 (Series of substantially equal periodic payments). The IRS will honor it if the schedule is documented.
- Keep a written SEPP plan — the method chosen, the interest rate, the AFR month used, the life-expectancy table, the starting balance, and the payment amount. If busted, the IRS will want to see it.
Method notes and the one-time switch
- We use the IRS Single Life Table (Pub 590-B, post-2022). Rev. Rul. 2002-62 also permits the Uniform Lifetime Table and the Joint & Last Survivor Table — but single life gives the LARGEST payment because it uses the shortest life expectancy. That's what most SEPP filers want.
- Notice 2022-6 one-time switch: once during the lock you may irrevocably change from either fixed method (amortization or annuitization) to the RMD method. Filers do this in a down market to shrink the required payment and avoid draining a shrunken account.
- The annuitization figure divides the balance by the Notice 2022-6 annuity factor: the present value of $1 a year beginning at your age and continuing for life, built from the mortality rates in Treas. Reg. §1.401(a)(9)-9(e) (Table 4) at your chosen rate, with the first payment at your current age (annuity-due).
Frequently asked questions
How much can I withdraw with a 72(t) SEPP?
Your annual SEPP payment depends on which of the three IRS methods you choose. On a $1,000,000 IRA at age 50, the RMD method pays about $27K/yr, while the fixed amortization and annuitization methods at the maximum 5% rate pay roughly $60K/yr. The fixed methods almost always pay more because they front-load the interest assumption.
What happens if I break the schedule?
If you modify or miss a SEPP payment before the later of 5 full years or age 59½, the 10% early-withdrawal penalty applies RETROACTIVELY to every distribution you took under the plan before age 59½ — plus interest. Payments made at or after 59½ were never subject to the 10%, so they are not recaptured. That's why 'busting' a SEPP is one of the most expensive mistakes in personal finance.
Which SEPP method pays the most?
Fixed amortization at the maximum rate — max(5%, 120% mid-term AFR) per Notice 2022-6 — almost always produces the largest payment. Fixed annuitization is typically within a few percent of amortization. The RMD method usually pays the least, but recalculates each year.
Can I change methods once my SEPP has started?
Yes — but only once, and only in one direction. Under Notice 2022-6 (and Rev. Rul. 2002-62 §2.03(b)), you may make a ONE-TIME irrevocable switch from either fixed method (amortization or annuitization) to the RMD method. Filers do this to reduce payments during a market downturn without triggering the retroactive penalty.
Does SEPP work on a 401(k)?
Technically yes, but IRAs are the cleanest vehicle. Most 401(k) plans require separation from service before they'll pay a series of substantially equal payments, and plan administrators can be restrictive. If you're still employed, roll (or partially roll) to an IRA first and run the SEPP from there.
What interest rate can I use?
Under IRS Notice 2022-6, you may use any rate up to the GREATER of 5% or 120% of the federal mid-term applicable federal rate (AFR) for either of the two months immediately preceding the first payment. The 5% floor was added in 2022 specifically to avoid the tiny payments that low-rate months produced under the old 120%-only rule.
This calculator implements Rev. Rul. 2002-62 as modified by Notice 2022-6. Numbers are estimates for planning. Verify the current-month AFR and consult a CPA before starting a real SEPP — the retroactive penalty for busting is severe.
