[ER-03] SEPP / 72(t): Substantially Equal Periodic Payments

The one-way door into penalty-free pre-tax income — and the single wrong dollar that reopens every penalty you avoided

Pillar: Early Retirement Mechanics · Applies to: Retirees under 59½ who need income from pre-tax accounts now and lack five years of bridge fuel Last verified: August 2026 · Refresh cadence: Evergreen mechanics; rate election is rate-environment-dependent — verify the AFR at election Related: ER-02 Roth Conversion Ladder · ER-04 Rule of 55 · ER-05 Accessing Money Early · ER-06 Sequence of Returns Risk · FN-02 Key Numbers · HC-01 ACA Bridge · TX-03 Withdrawal-Order Sequencing

Not advice. A SEPP is close to irrevocable, and a single arithmetic or administrative error retroactively reinstates every penalty it avoided, with interest. Have the calculation verified in writing by your custodian and a CPA before the first distribution, and keep the documentation for the life of the plan plus the statute of limitations.

TL;DR

• SEPP (Substantially Equal Periodic Payments, IRC §72(t)(2)(A)(iv)) is the exception that lets you draw from an IRA or 401(k) before 59½ without the 10% early-distribution penalty. You still owe ordinary income tax. ✅
• The price is rigidity: payments must run for the longer of 5 years or until age 59½, on a fixed schedule you cannot resize. Start at 50 and you’re committed for 9½ years; start at 57 and you’re committed to 62, not 59½. ✅
• Three calculation methods — RMD, fixed amortization, fixed annuitization. Amortization is the workhorse; RMD pays roughly half as much but flexes with the market.
• Notice 2022-6 changed the economics. The interest rate may be the greater of 5% or 120% of the federal mid-term rate — where the old rule was 120% of mid-term alone. In a low-rate decade that lifted payouts by roughly 33–70%. ✅
• Busting it is catastrophic and retroactive. A modification reinstates the 10% penalty on every distribution you took before 59½ — not just the offending dollar — plus interest from each year’s distribution date. ✅
• The essential defensive move is account splitting: SEPP only the slice of IRA you need, and leave the rest in a separate IRA you can touch in an emergency without touching the plan.
• It is usually the wrong tool if you have taxable/Roth-basis bridge fuel (ER-02) or you’re 55+ separating from an employer with a cooperative 401(k) (ER-04). SEPP is what you use when you need pre-tax income now and have no runway.

1. What You’re Actually Signing Up For

A SEPP is a commitment to take a computed amount out of a specific retirement account every year, on schedule, for a fixed term. In exchange, the 10% penalty is waived.

The duration rule is the part people misread. Payments must continue for the longer of:

• five years (60 months from the first distribution), or
• until you reach age 59½.

Start age	Must continue until	Years locked
45	59½	14½
50	59½	9½
55	59½	4½ → extended to 60 by the 5-year rule
57	62	5
58	63	5

So SEPP gets less attractive as you approach 59½ — the 5-year minimum drags the commitment past the age at which you’d have been free anyway. Between about 55 and 59, check ER-04 (Rule of 55) first; it does the same job with none of the lock-in.

Where it works: IRAs (traditional, SEP, SIMPLE) at any time, and employer plans only after separation from service. You can run a SEPP on one IRA while leaving others untouched — the plan attaches to the account, not to you.

Practical mechanics:

• You may take the full annual amount in the first calendar year regardless of the month you start, or prorate — pick one, document it, be consistent.
• Frequency (monthly, quarterly, annual) is yours; the annual total is what must match.
• Distributions are ordinary income, reported on Form 1099-R. If the custodian codes it “1” (early distribution, no known exception) rather than “2”, you claim the exception on Form 5329. Expect to do this; many custodians will not code it “2”. ◻️

2. The Three Calculation Methods

All three use your account balance, your age, and an IRS life-expectancy table (Single Life, Uniform Lifetime, or Joint and Last Survivor — Notice 2022-6 permits any of the three). ✅

Method	How it works	Payment size	Recalculated?	Best for
Required Minimum Distribution	Balance ÷ life-expectancy factor, every year	Lowest (~half of amortization)	Yes — annually, on the new balance	Wanting the smallest forced income, or tolerating variability
Fixed amortization	Balance amortized over life expectancy at a chosen interest rate — like a mortgage payment	Highest	No — fixed for the term	The default choice when you need maximum income
Fixed annuitization	Balance ÷ an annuity factor from the IRS mortality table at a chosen rate	Close to amortization	No — fixed for the term	Rarely chosen; occasionally edges out amortization ◻️

The tradeoff in one line: amortization gives you the most money and zero flexibility; the RMD method gives you about half as much but automatically shrinks when markets fall — which is exactly when a fixed payment does the most damage to a portfolio (ER-06).

The rate election (this is the modern story). For the two fixed methods you choose an interest rate. Under Notice 2022-6, it may be any rate up to the greater of:

1. 5.00%, or
2. 120% of the federal mid-term rate for either of the two months preceding the month your first distribution occurs.

Before 2023 the 5% floor didn’t exist — you were capped at 120% of mid-term, which sat under 3% for most of a decade and made SEPP payments punishingly small. The floor raised payouts by roughly 33–70% depending on age and balance, and it is the reason SEPP is worth reconsidering if you dismissed it years ago. ✅

As of early 2026, 120% of the federal mid-term rate was running below 5% (January 2026: 4.57%), so the 5% floor governs for most plans started in this environment. ◻️ Rates move monthly — pull the two preceding months’ AFRs from the IRS before you elect, and use the higher permitted figure if you want maximum income.

3. Worked Example: Age 50, $600,000 IRA

Single Life Expectancy factor at 50: 36.2. ◻️ (verify against the current table)

Method	Calculation	Annual payment
RMD method	$600,000 ÷ 36.2	$16,575 (recalculated yearly)
Fixed amortization @ 5%	$600,000 × 0.05 ÷ (1 − 1.05⁻³⁶·²)	$36,187
Fixed amortization @ 2% (the pre-2023 world)	$600,000 × 0.02 ÷ (1 − 1.02⁻³⁶·²)	$23,449

The 5% floor is worth $12,738/year to this person — a 54% increase over what the same account would have produced under the old rate cap. ✅

He is locked in from 50 to 59½ — ten annual payments. Over that span he will withdraw roughly $362,000 under amortization.

The critical refinement: don’t SEPP the whole account

Suppose he only needs $30,000/year. Running the SEPP on the full $600,000 forces $36,187 of income on him — $6,187 more than he needs, every year, taxed, and counted as ACA MAGI (§5).

Instead, split the IRA first, then SEPP only the smaller piece:

Required SEPP balance = $30,000 ÷ $36,187 × $600,000 ≈ $497,400

Account	Balance	Role
IRA-A (SEPP)	~$497,400	Produces exactly $30,000/year ✅
IRA-B (reserve)	~$102,600	Untouched. Available for emergencies (10% penalty applies, but no bust)

This is the single most important structural decision in SEPP planning. The reserve account converts a catastrophic risk (busting the plan) into a merely expensive one (paying 10% on an emergency withdrawal). Split before the first distribution — moving money afterward is itself a modification.

---

4. Busting It: What Counts, and What It Costs

A modification before the term ends detonates the plan. Under §72(t)(4), the exception is treated as never having applied: the 10% penalty is recaptured on every distribution taken before 59½, plus interest for the deferral period, charged from each year’s distribution date. ✅

What our 50-year-old would owe if he busts in year 8:

	Amount
Distributions taken (8 × $36,187)	$289,496
Recaptured 10% penalty	$28,950
Plus interest from each year’s distribution date	Additional ✅

He does not owe 10% on the offending dollar. He owes it on all $289,496.

What modifies a plan:

• Taking any amount other than the computed one — a dollar extra, or a dollar short
• Missing a year, or forgetting the December distribution
• Rounding wrong — shorting the calculation by $50 busts it exactly as thoroughly as shorting it by $50,000
• Adding money to the SEPP account (a rollover in, a contribution)
• Rolling or transferring money out of the SEPP account, including partial transfers ◻️
• Changing the payment amount — with one exception (§5)

What does not modify it: ✅

• Death or disability of the account owner
• Exhausting the account by following the method faithfully — if the balance runs to zero, that’s not a bust
• The one permitted method switch (§5)

Administrative reality: most busts are clerical, not strategic. A custodian changes its distribution system; an automatic payment fails in December; someone consolidates accounts without remembering which IRA carries the plan. Treat the SEPP account as radioactive: no consolidation, no rebalancing across it, no address-change-triggered re-paperwork without confirming the schedule survived.

---

5. The One Escape Hatch

You are permitted exactly one method change, and only in one direction: from fixed amortization or fixed annuitization → to the RMD method. This is explicitly not a modification. ✅

It is a genuine relief valve. If markets fall hard, a fixed payment becomes a rising percentage of a shrinking portfolio — the sequence-of-returns problem in its purest form (ER-06). Switching to the RMD method roughly halves the payment and re-links it to the actual balance.

What it does not do: let you increase payments, switch back, or stop early. The door swings one way, once. Use it when a fixed payment is genuinely threatening the account’s survival — not because you’d prefer less income this year.

---

6. The ACA Problem Nobody Prices In

A SEPP is forced MAGI. Every dollar counts toward the ACA calculation in HC-01, and you cannot turn it off for a decade.

This collides with everything early retirees do to steer income:

• You cannot dial income down to stay under the 400% FPL cliff in a year with other income.
• You cannot cut it to land in a cost-sharing-reduction band.
• You cannot stop it to clear the Medicaid floor question in either direction.
• Roth conversions stack on top of it, so ladder rungs get smaller or vanish (ER-02).

For a retiree at $30,000 of SEPP income, that’s roughly 142% of FPL for a household of two — actually a helpful floor if you’d otherwise be routed to Medicaid and didn’t want to be. For a retiree at $70,000 of SEPP income, it’s a permanent ceiling on subsidy planning.

Design the SEPP amount against your ACA plan, not just your budget. The account-splitting math in §3 is how you do it: choose the target income first, then size the SEPP balance to produce exactly that.

7. Three Scenarios

A. No bridge fuel, needs income now (age 48, $850k IRA, $40k taxable). A Roth ladder needs five years of side funding; she has about one. SEPP is the right tool. She splits the IRA: $520k into the SEPP account producing ~$31k/year at 5% amortization ◻️, and $330k reserved. She’s locked until 59½ — 11½ years — and accepts it because the alternative is paying 10% on everything. Her ACA plan is built around a fixed ~$31k MAGI floor, which lands her comfortably in the 94% AV cost-sharing band (HC-01 §3).

B. The one who shouldn’t (age 56, separating from employer, 401(k) intact). He’s about to start a SEPP. He shouldn’t: the Rule of 55 (ER-04) lets him take penalty-free distributions directly from that 401(k) — any amount, any schedule, no lock-in — because he separated in or after the year he turned 55. A SEPP started at 56 would bind him until 61 under the 5-year rule, worse than the age it was meant to bridge. Check Rule of 55 eligibility before ever calculating a SEPP. The one thing that forfeits it: rolling the 401(k) to an IRA first.

C. The bust (age 52, year 6). Started at 46 with $28,000/year. In year 6, a new advisor consolidates three IRAs “for simplicity,” rolling $180,000 into the SEPP account. That’s a modification. Six years of distributions — $168,000 — get the 10% recapture: $16,800, plus interest from each year’s date. Nothing about the consolidation was wrong except the account it touched. The reserve-account structure in §3 wouldn’t have prevented this one; a written “do not touch” note on the account, shared with every advisor and custodian, would have.

💡 Pro-Tips

1. Check ER-04 Rule of 55 and ER-05 457(b) access before calculating anything. Both give penalty-free money with no lock-in. SEPP is the fallback, not the default.
2. Split the IRA before the first distribution. Size the SEPP account to your target income; keep the remainder in a reserve IRA you can raid without busting.
3. Elect the highest permitted rate only if you want maximum income. You may use any rate up to the cap — electing lower is legal and produces a smaller, more sustainable payment.
4. Get the calculation in writing from two sources (custodian + CPA), and keep it with the AFR you used and the table you used, forever.
5. Never automate the December payment and forget it. Verify the annual total hit the exact computed figure every single year, in November.
6. Remember the one-time RMD switch exists — it’s your only lever in a bad market, and using it early wastes it.
7. Expect a “1” on the 1099-R and plan to file Form 5329 claiming exception code 02 each year.
8. Model the ACA consequence for the full term, not year one — a decade of forced MAGI is a decade of constrained subsidy planning (HC-01).

⚠️ Common Pitfalls

1. Starting a SEPP at 56–58 and extending the commitment past 59½ under the 5-year rule.
2. Rolling a 401(k) to an IRA first, forfeiting Rule-of-55 access, then discovering SEPP was the harder path (ER-04).
3. Running the SEPP on the entire IRA, forcing more income than you need, forever.
4. Any rollover into or partial transfer out of the SEPP account — a bust, regardless of intent.
5. Shorting or overshooting the annual amount by any margin, including rounding.
6. Assuming the penalty applies only to the excess. It applies retroactively to every pre-59½ distribution, with interest.
7. Letting a new advisor or custodian “tidy up” accounts mid-plan.
8. Choosing amortization for maximum income, then watching a bear market turn a fixed payment into forced selling (ER-06).
9. Forgetting that SEPP income is ACA MAGI and blowing a subsidy plan you can’t unwind.
10. Using the one-time RMD switch casually and having nothing left when it’s actually needed.
11. Assuming pre-2023 payout math still applies — the 5% floor materially changed the calculus.

✅ Actionable Checklist

Before committing

• Rule out ER-04 Rule of 55, ER-05 457(b)/taxable/Roth-basis access, and ER-02 the Roth ladder
• Compute the true lock-in end date (longer of 5 years or 59½)
• Decide the target annual income first — from budget and ACA plan
• Pull the two preceding months’ federal mid-term AFRs; compare 120% of each against 5%
• Run all three methods; choose deliberately (income vs. flexibility)

Setting it up

• Split the IRA — SEPP account sized to target; reserve account for emergencies
• Get the calculation confirmed in writing by custodian and CPA
• Document: method, rate, table, factor, balance, valuation date, first distribution date
• Flag the SEPP account “do not modify” with every institution and advisor

Every year of the term

• November: verify the year’s distributions total exactly the computed amount
• File Form 5329 (exception code 02) if the 1099-R is coded “1”
• Confirm no rollovers, contributions, or transfers touched the account
• Re-check the ACA/MAGI plan against the fixed income (HC-01)

Ending it

• Confirm the final required distribution before stopping — the last year is the most common bust
• After the term, resume normal withdrawal sequencing (TX-03)

State notes (→ ST-01, ST-03): SEPP distributions are ordinary income for state purposes in most taxed states, and the federal 10% penalty has state analogues in a few places — California, notably, adds its own 2½% additional tax on early distributions (6% for SIMPLE IRAs inside the first two years). A properly-run SEPP is exempt from it: California recognizes the substantially-equal-periodic-payments exception as exception code 02 on FTB Form 3805P, the same code you claim federally on Form 5329. ✅ Two caveats that survive the verification: California states plainly that it “does not conform to all of the federal exceptions,” so do not assume any other §72(t) exception carries over — check 3805P’s list before relying on one ✅ — and a bust presumably recaptures the state tax alongside the federal, on the same retroactive basis. ◻️ In no-income-tax states (WA, FL, TX, NV, TN, and others) the entire SEPP stream is federal-only, which materially improves the after-tax payout versus the same plan run in a high-tax state (FN-02). Because a SEPP locks income for up to 14 years, it is the retirement decision most exposed to a future state move — a plan sized in a no-tax state and then carried into a 9% state loses real spendable income with no way to resize. Sequence any planned relocation before electing.
