Rule 72(t) Calculator: How SEPP Payments Work

Section 72(t) generally imposes a 10% additional tax on the taxable portion of an early distribution from a qualified retirement plan. One exception applies to distributions made as a series of substantially equal periodic payments over the account owner’s life expectancy—or the joint life expectancies of the owner and a designated beneficiary—when the requirements are satisfied. [1] [2]

Notice 2022-6 provides three methods that are automatically treated as satisfying the payment-calculation portion of the exception when applied correctly. They do not produce one universal answer. A calculator must disclose which method, balance date, table, age, beneficiary assumption, and interest rate it used. [1] [3]

For the fixed amortization and fixed annuitization methods, Notice 2022-6 permits an interest rate no greater than the greater of 5% or 120% of the federal mid-term rate for either of the two months immediately before the month of the first payment. “No greater than” matters: a calculator should not silently assume the maximum or imply that a higher payment is automatically preferable. [1] [3]

All three methods use approved longevity information. The RMD method can use the Uniform Lifetime Table, Single Life Table, or Joint and Last Survivor Table under the conditions described in the notice. Fixed annuitization uses the mortality table specified by Notice 2022-6. The selected table and beneficiary facts may change the result. [1] [3]

• Confirm the month in which the first payment will actually occur.
• Retain the applicable federal mid-term rates for both lookback months.
• Document the chosen permissible rate rather than only the calculator result.
• Record the owner’s attained age for the distribution year.
• Verify whether a beneficiary and joint-life table are valid for the method.
• Save the account statement supporting the selected valuation date.

The IRS provides an example of a person age 50 with a $400,000 IRA beginning a series in 2023. Using the Single Life Table and the RMD method, the first payment is $400,000 divided by 36.2, or $11,050. Using fixed amortization with a permitted 4% rate and the same 36.2-year life expectancy, the annual amount is $21,102. The IRS example also calculates a fixed-annuitization result using its prescribed mortality table. [1]

This comparison is not a 2026 recommendation or a quote for a current visitor. It repeats selected figures from the IRS example to show why method choice matters. A 2026 series needs current facts, an appropriate valuation, the correct table, and the permitted rate for its actual start month.

The larger number is not automatically better. It creates more current cash flow, but also distributes more retirement money, generally creates more taxable income, and may increase the chance of depletion or affect income-linked items. The RMD-method amount can rise or fall each year with the balance and table factor.

The series generally cannot be modified before the later of the fifth anniversary of the first payment or the date the taxpayer reaches age 59½. This “later of” rule is why starting age matters so much. Someone who begins at age 50 may face a commitment of roughly nine and a half years, while someone who begins at age 58 may still need to continue until five full years have passed. [1] [3]

The IRS describes strict account and payment boundaries. Once a SoSEPP is established, the taxpayer generally cannot add to the selected account or take payments other than the series payments. Each series belongs to one account and must be managed independently. An annual amount may be paid annually, quarterly, or monthly, subject to custodian limitations, but the installments must total the required annual amount in the proper year. [1]

If a prohibited modification occurs early, the current year may include the 10% additional tax on taxable distributions, plus a recapture tax equal to the additional tax that would have applied in prior years and interest for the deferral period. Death, disability, qualified public-safety distributions, complete account depletion, and specified changes receive specialized treatment; they should not be generalized into broad exceptions. [1] [3]

A SEPP distribution and a Roth conversion are different transactions. A SEPP pays money out to the taxpayer under an exception to the 10% additional tax. A Roth conversion moves eligible retirement money into a Roth account and generally includes the previously untaxed amount in income.

Using the account dedicated to a SEPP for a conversion could change that account or its distributions and jeopardize the series. A separately maintained retirement account may offer a cleaner boundary, but the conversion still creates its own tax, cash-flow, Medicare, Marketplace, Social Security, and state-tax questions. Account separation alone does not make either transaction appropriate.

1. Which single retirement account would support the payment series?
2. What exact account balance and valuation date are supportable?
3. Which IRS method and life-expectancy table would be used?
4. If using a fixed method, what rate is permitted for the actual starting month?
5. How much after-tax spending does the household need each year?
6. How will ordinary income tax and state tax be paid?
7. Could the income affect ACA Premium Tax Credits, Medicare IRMAA, or other thresholds?
8. Can the household avoid additions, extra withdrawals, and account changes for the entire restricted period?
9. What happens if markets fall or the account depletes faster than illustrated?
10. Which custodian procedures and tax forms will document each payment?
11. Have alternatives and other early-distribution exceptions been reviewed?
12. Who will monitor the annual total and the exact date when the restriction ends?

If any answer is unknown, a calculator result is premature. Gather statements, payment needs, ages, beneficiary details, tax-return context, insurance information, and custodian procedures before treating a modeled amount as operational.
