Substantially Equal Periodic Payments: Using 72(t) to Tap Retirement Money Early

Substantially equal periodic payments, usually called a 72(t) plan or SEPP, are a way to take money out of a retirement account before age 59½ without paying the 10% early-distribution penalty. You commit to a fixed schedule of withdrawals calculated by an IRS-approved method, and you keep taking them for a set minimum period. In return, the penalty that normally applies to early withdrawals is waived. The income tax is not waived; only the penalty is.

The rule takes its name from Section 72(t) of the Internal Revenue Code, and the exception itself is in §72(t)(2)(A)(iv). It is one of the few clean ways to access retirement savings early, but it is also unforgiving: break the schedule and the IRS can claw back the penalty on everything you have withdrawn, plus interest. This article explains how a SEPP is built, the three calculation methods, the rules that lock you in, and the mistakes that turn a legitimate plan into a tax bill.

The figures below are illustrative examples used to show the mechanics. They are not advice or current interest rates. The IRS updates the permitted rates and life expectancy tables, so confirm your own numbers with a tax adviser before starting a plan.

What a SEPP is for

The standard rule is simple: take money out of a traditional IRA or a 401(k) before 59½ and you generally owe income tax plus a 10% additional tax on the amount. That 10% is designed to discourage raiding retirement accounts early.

A SEPP is a statutory exception. If you draw the money as a series of substantially equal periodic payments, the 10% penalty does not apply, even though you are years short of 59½. It exists for people who genuinely need to live on retirement money early, most often those who retire before the normal age and have savings locked in tax-advantaged accounts.

It is worth comparing SEPP with the other main early-access route. If you have left an employer at the right age, the rule of 55 can let you take penalty-free withdrawals from that employer's 401(k) with far less rigidity than a 72(t) plan. SEPP is the tool when the rule of 55 does not fit, for example when your money is in an IRA or you retired too young to use it.

The three IRS-approved methods

You cannot simply withdraw whatever you like and call it a SEPP. The amount must be calculated using one of three methods the IRS recognises, set out most recently in Notice 2022-6, which replaced the earlier guidance for plans starting on or after 1 January 2023.

• Required minimum distribution method. You divide the account balance by a life expectancy factor from an IRS table each year. The payment is recalculated annually, so it moves up and down with the account balance. It usually produces the smallest payment and is the only method where the amount changes each year.
• Fixed amortization method. You amortise the account balance over your life expectancy using a chosen interest rate, producing a fixed annual payment that stays the same every year. This generally gives a larger, stable payment.
• Fixed annuitization method. You divide the balance by an annuity factor based on a mortality table and an interest rate. It also produces a fixed annual amount, usually close to the amortization result.

For the two fixed methods, the interest rate you may use is capped. Under Notice 2022-6, the rate can be no more than the greater of 5% or 120% of the federal mid-term rate for one of the two months before payments begin. The addition of that 5% floor was significant: when market rates are low, being able to use 5% lets people take a meaningfully larger payment than the old rules allowed.

Here is an illustrative comparison of how the method choice affects the payment. Suppose someone has a $500,000 IRA. The RMD method might produce roughly $18,000 in the first year and vary after that; the amortization method, using a permitted rate, might produce a level figure closer to $25,000 that stays fixed each year. These numbers are purely to show the pattern, not a quote; your figures depend on your age, balance, the table, and the rate on your start date.

The rules that lock you in

The reason a SEPP demands care is the commitment. Once you start, you must keep taking the payments, unchanged, for the longer of five years or until you reach age 59½. Whichever comes later governs.

That produces two very different situations depending on your age:

When you start	How long you are locked in
Age 50	Until 59½ — nearly 10 years
Age 57	Until 62 — the five-year rule extends past 59½
Age 54	Until 59½ — just over five years

The younger you start, the longer the commitment, because you must reach 59½ no matter what. Someone starting at 50 is signing up for close to a decade of fixed withdrawals.

During that period the payments must stay substantially equal. You cannot take more when you fancy it, skip a year, or roll the account over in a way that changes the balance the plan is built on. Almost any deviation counts as a modification.

What happens if you break it

This is where a SEPP becomes dangerous if handled casually. If you modify the series before the required period ends, other than by death or disability, the penalty relief is retroactively revoked. The 10% additional tax is then applied to every distribution you took under the plan from the beginning, and interest is charged for the deferral. A plan that ran smoothly for four years can generate a penalty on all four years' worth of withdrawals in one go.

Common ways people accidentally break a SEPP include taking an extra withdrawal for an emergency, changing the payment amount, rolling money into or out of the account mid-plan, or miscalculating the annual figure. Because the consequence is so severe, many people set up a SEPP on only part of their savings, splitting off a separate IRA sized to produce the payment they need. That way the rest of their retirement money stays outside the plan and available without breaking the schedule. Handling account transfers carefully matters here; the general mechanics of moving retirement money are covered in the 401(k) rollover guide.

There is one sanctioned escape hatch: the IRS permits a one-time switch from either fixed method to the RMD method, which can lower payments if a falling balance makes the fixed amount unsustainable. That switch is allowed and does not count as a modification, but it must be done correctly.

Where a SEPP fits in a wider plan

A 72(t) plan solves one problem well: bridging income from an early retirement to the age when penalty-free access opens up anyway. It is rarely the whole answer.

Because the payments are fixed and taxed as ordinary income, a SEPP interacts with the rest of your tax picture. Large fixed withdrawals can push you into a higher bracket or affect other thresholds, which is why it sits alongside the broader ideas in retirement tax strategies and creating retirement income from savings. Some people prefer to combine a modest SEPP with other income sources rather than sizing one large plan that dominates their taxable income for a decade.

The judgement, as ever, is not just "can I do this" but "should I, and for how much." A SEPP is a precise instrument. Used deliberately, on a right-sized account, with the calculation confirmed and the commitment understood, it does exactly what it promises. Used loosely, it converts a legal early-access route into a retroactive penalty. The difference is entirely in the discipline of following the schedule.

Frequently asked questions

What accounts can I use for a 72(t) SEPP?

You can set up a SEPP from a traditional IRA and, in many cases, from a 401(k) or similar employer plan, though plan rules vary and some require you to have separated from the employer first. IRAs are the most common source because you control them directly. Roth IRAs can technically be used, but because Roth withdrawals have their own ordering and tax rules, most people use pre-tax accounts.

Does a SEPP avoid income tax on my withdrawals?

No. A SEPP only waives the 10% early-distribution penalty. The withdrawals from a pre-tax account are still taxable as ordinary income in the year you take them. The benefit is purely avoiding the extra 10%, not the income tax itself.

How long do the payments have to continue?

For the longer of five years or until you reach age 59½. If you start young, reaching 59½ is the binding condition, so someone who begins at 50 is committed for nearly a decade. Someone who begins at 57 must continue until about 62 because the five-year rule extends past 59½.

What if my account loses value and the payments become too large?

The IRS allows a one-time switch from either fixed method to the required minimum distribution method, which recalculates the payment against the current balance and generally lowers it. This switch is specifically permitted and does not count as breaking the plan, but it must be documented and done correctly.
