Understanding Substantially Equal Payments

Maybe you've heard of substantially equal periodic payments, sometimes referred to as SEPP, or maybe more commonly "72(t)" or "72(t) distributions." Most people probably haven't heard of these, but if you're planning to retire early, SEPP payments are worth understanding — especially after the IRS dramatically improved them in 2022.

Here are the two fundamental dilemmas of early retirement:

1. How do I access my retirement savings before 59\u00bd? Most withdrawals from 401(k)s and traditional IRAs before age 59\u00bd trigger a 10% early withdrawal penalty on top of income taxes.
2. How do I minimize taxes in early retirement? Even if you can access your money, you want to do it as tax-efficiently as possible.

One popular solution is the Roth IRA conversion ladder — converting traditional IRA funds to Roth each year and waiting 5 years to withdraw contributions tax- and penalty-free. But what if you're still in an employer-sponsored plan? Or you need income immediately and can't wait 5 years?

That's where SEPP payments come in. And thanks to IRS Notice 2022-6, they're now significantly more generous than they used to be.

What Are Substantially Equal Periodic Payments?

SEPP payments — also called 72(t) distributions — are an IRS-approved method for withdrawing money from retirement accounts before age 59\u00bd without paying the 10% early withdrawal penalty. They're available for IRAs (traditional, SEP, SIMPLE) and employer-sponsored plans like 401(k)s and 403(b)s.

The IRS imposes three critical rules on SEPP plans:

• Duration: Payments must continue for at least 5 years or until you reach age 59\u00bd — whichever is longer. If you start at age 50, you're locked in for 9.5 years.
• No changes: You cannot modify, skip, or stop payments. You also cannot make contributions, conversions, or rollovers to the account during the SEPP period.
• Retroactive penalty: If you violate either rule above, the IRS applies the 10% penalty retroactively to every distribution you've taken — plus interest. This is the "sealed container" rule.

Important exception: If you separate from service (leave your employer) at age 55 or later, you can take penalty-free withdrawals from that employer's plan without setting up a SEPP. Under SECURE 2.0, this was expanded to age 50 for public safety employees. This is called the "Rule of 55."

How SEPP Payments Can Fund Your Early Retirement

The biggest benefit is straightforward: SEPP payments let you access your retirement savings without the 10% early withdrawal penalty. You'll still pay ordinary income tax on the distributions, but if you're in early retirement with little other income, your tax bracket could be very low — potentially 10-12%.

An Unexpected Benefit: Reducing Future Required Minimum Distributions

Under the SECURE 2.0 Act, Required Minimum Distributions (RMDs) now begin at age 73 (for those born 1951-1959), and will increase to age 75 starting in 2033 (for those born 1960 or later). When you reach RMD age, the IRS forces you to withdraw a minimum amount each year based on your account balance.

If you've spent a decade or more taking SEPP distributions, your traditional IRA balance will be significantly smaller by the time you reach 73 or 75. That means smaller RMDs, which means less taxable income in your 70s and beyond — exactly when you might have Social Security and other income pushing you into higher brackets.

Think of it this way: SEPP distributions shift income from your high-tax years (post-73) to your low-tax years (early retirement). That's genuine tax alpha.

SEPP Payment Examples: The 5% Floor in Action

Let's run the numbers with a concrete example. Assume you're age 50 with a $400,000 traditional IRA and you use the IRS Single Life Expectancy Table (which gives a factor of 36.2 years at age 50 under the 2022 updated tables).

Method 1: Required Minimum Distribution

The simplest calculation: divide your balance by your life expectancy factor.

$400,000 \u00f7 36.2 = $11,050 per year ($921/month)

This is recalculated each year based on your actual balance and updated life expectancy. The interest rate doesn't matter for RMD — it's purely balance \u00f7 life expectancy.

Method 2: Fixed Amortization (Most Popular)

This works like a mortgage payment in reverse. You amortize your account balance over your life expectancy at a chosen interest rate.

At the 5% floor rate: $400,000 amortized over 36.2 years at 5% = $24,125 per year ($2,010/month)

That's $13,075 more per year than the RMD method — and $5,915 more than the same calculation would have produced at the old 2.98% rate ($18,210/year). The 5% floor transformed this method from "barely covering groceries" to "covering most basic expenses."

Method 3: Fixed Annuitization

Uses IRS annuity mortality factors instead of straight life expectancy. Produces slightly higher payments than amortization in most cases.

At the 5% floor rate: approximately $25,187 per year ($2,099/month)

The annuitization method is more complex to calculate (you need the IRS annuity factor from Revenue Ruling 2002-62), but it produces the highest fixed payout of the three methods.

One-Time Switch: Fixed to RMD

The IRS allows a one-time switch from either fixed method to the RMD method — but not the reverse, and not between the two fixed methods. This can be useful if your account balance drops significantly and you want to reduce withdrawals to preserve your portfolio.

The IRA Rollover Strategy: Right-Sizing Your SEPP

One of the smartest moves when planning a SEPP is to roll only a portion of your employer plan into a traditional IRA and base your SEPP on that segregated account.

Here's why: your SEPP payment is calculated on the entire balance of the account. If you have $1 million in a 401(k) and start a SEPP on the full amount, you might get more income than you need — and you'd be draining your retirement savings faster than necessary.

Instead, try this approach:

• $1,000,000 in your 401(k)
• Roll $400,000 into a new traditional IRA \u2192 start SEPP on this account ($24,125/year at 5%)
• Leave $600,000 in the 401(k) \u2192 continues growing tax-deferred

The $600,000 left in your 401(k) keeps compounding. By the time your SEPP ends (at 59\u00bd), that $600,000 could have grown to $900,000+ — giving you a significant nest egg for traditional retirement.

Pro tip: If you have both pre-tax and Roth funds in your 401(k), roll only the pre-tax portion to a traditional IRA for your SEPP. Keep your Roth funds separate — Roth contributions can always be withdrawn penalty-free, and they provide tax-free income later.

The Potential Pitfalls of a SEPP

SEPP payments are powerful, but they come with real risks. Here's what to watch for:

• Choose the right withdrawal rate. Even though the 5% interest rate is used for the calculation, your actual investment returns matter. If your SEPP requires $24,125/year from a $400,000 account (6% withdrawal rate), you need your investments to keep pace. A prolonged market downturn could significantly erode your balance. Consider the safe withdrawal rate research when sizing your SEPP.
• Inflation is not built in. Fixed methods produce the same payment every year. After 10 years of inflation, your $24,125 will buy significantly less. Plan for this by having supplemental income sources that can grow over time.
• Don't modify the plan. We've said it before: the retroactive penalty is devastating. No extra withdrawals, no contributions, no rollovers. If you need emergency funds, take them from a different account.
• Consult a tax professional. The IRS rules around 72(t) plans are technical and the consequences of errors are severe. A CPA or tax attorney experienced in early retirement distributions is worth the cost.

You Probably Don't Want to Rely on SEPP Alone

Even with the improved 5% rate, a SEPP plan is best used as one component of a diversified early retirement income strategy. Here's a practical framework:

• Years 1-5: SEPP distributions + taxable account withdrawals cover expenses while you build a Roth conversion ladder.
• Years 5+: Roth conversion ladder comes online, providing tax-free income. SEPP continues alongside.
• Age 59\u00bd+: SEPP ends. Full access to all retirement accounts. Roth ladder continues tax-free.
• Age 73/75+: RMDs begin, but your traditional IRA is smaller thanks to years of SEPP distributions and Roth conversions.

The real power is in combining strategies. A SEPP provides the bridge income you need while slower strategies (like the Roth ladder) mature. Together, they create a comprehensive early retirement income plan.
