Section 72(t) of the tax code allows you to take substantially equal periodic payments (SEPP) from an IRA before age 59½ without the 10% early withdrawal penalty. Income tax still applies. But the penalty is waived if you follow the rules exactly.
This is an early retirement tool. Get it wrong and the IRS applies the 10% penalty retroactively to every payment made, plus interest.
The Three Calculation Methods
The IRS allows three methods for calculating SEPP amounts:
| Method | Description | Flexibility |
|---|---|---|
| Required Minimum Distribution (RMD) | Based on account balance / life expectancy | Recalculated annually: payment changes each year |
| Fixed Amortization | Level payment calculated once | Fixed forever |
| Fixed Annuitization | Level payment using annuity factor | Fixed forever |
Fixed amortization and fixed annuitization are similar in output. The RMD method produces lower, variable payments. Useful if you want to keep more in the account.
How Much Will 72t Pay?
Fixed Amortization Method, $600,000 IRA, starting at age 50:
The IRS publishes a "reasonable interest rate". Up to 120% of the mid-term Applicable Federal Rate (AFR). In 2026, assume 5.8%.
Using single life expectancy table (age 50): 36.2 years remaining.
Annual payment = $600,000 amortized over 36.2 years at 5.8% = approximately $37,500/year ($3,125/month).
RMD Method (lower): Annual payment = $600,000 / 36.2 = $16,575/year ($1,381/month).
Payment Amounts by IRA Balance and Age
Fixed amortization method at 5.8% rate, approximate annual payments:
| IRA Balance | Age 45 | Age 50 | Age 55 |
|---|---|---|---|
| $300,000 | $17,500 | $18,700 | $20,400 |
| $500,000 | $29,100 | $31,100 | $34,000 |
| $750,000 | $43,700 | $46,700 | $51,000 |
| $1,000,000 | $58,200 | $62,200 | $68,000 |
Payments must continue until you reach 59½ OR 5 years have passed. Whichever is LONGER. A 50-year-old starting a 72t plan must continue to 59½ (9 years). A 57-year-old must continue until 62 (5 years minimum).
The Rules You Cannot Break
| Rule | What It Means |
|---|---|
| Equal payments | Same amount each year (or same formula for RMD method) |
| No modifications | Cannot increase, decrease, stop, or add to the plan |
| Minimum duration | 5 years OR age 59½, whichever is longer |
| One account | The 72t plan applies to one IRA: you can have other IRAs untouched |
| IRS calculation rules | Must use approved method and IRS life expectancy tables |
Breaking the plan: If you modify any payment before the plan completes, the IRS treats all prior distributions as non-qualifying. Every distribution is subject to the 10% early withdrawal penalty retroactively, plus interest. This can be a six-figure mistake.
The Separate IRA Strategy
The 72t plan applies to the specific IRA you designate. If you have $1,000,000 in an IRA and only need $30,000/year, you can:
- Roll $500,000 into a separate IRA
- Start the 72t plan on the $500,000 IRA only
- Leave the other $500,000 untouched until 59½
This preserves flexibility. You need income from one account, not the full balance.
Tax Treatment
SEPP distributions are taxable as ordinary income. There is no penalty, but income tax applies in full. If you converted your IRA to a Roth, distributions from the Roth may be tax-free (after the 5-year holding period and age requirements for Roth IRA).
Alternatives to Consider First
| Alternative | Tradeoff |
|---|---|
| Roth conversion ladder | 5-year wait per conversion before penalty-free access |
| Roth contributions | Always accessible penalty-free |
| Taxable brokerage | No restrictions, but taxable gains |
| Rule of 55 (401k) | Leave employer at 55+, access that employer's 401k penalty-free |
| Part-time work | Reduces withdrawal need |
The 72t plan is irreversible once started. Roth conversion ladders and taxable accounts offer more flexibility for early retirees who can plan 5+ years ahead.
Frequently Asked Questions
Can I change the 72t method once started?
Yes, once. The IRS allows a one-time change from the fixed amortization or fixed annuitization method to the RMD method. This is useful if the account declines significantly and you want to reduce distributions to preserve capital. The switch is a one-time, one-direction option.
What if my IRA runs out of money before the 72t period ends?
This is the primary financial risk of 72t plans. Particularly if you start large payments on a small balance. If the account is depleted, the distributions stop. Whether the IRS considers this a modification (triggering retroactive penalty) is a gray area. It is generally argued that account depletion is not a voluntary modification. To avoid this risk, ensure the annual distribution is below the account's annual growth rate.
Is a 72t distribution better than a 401k loan?
Different situations. A 401k loan requires repayment; failure to repay becomes a distribution with penalty. A 72t plan is not a loan. There is no repayment obligation. But 72t is irrevocable for years; a 401k loan can be repaid early. For short-term needs, the loan is more flexible. For retirement income planning, 72t is appropriate.
