The Stretch IRA Is Officially Dead: In 2026 the 'Empty It in 10 Years' Rule Is Fully Enforced — and Skipping a Single Annual Withdrawal Now Costs a 25% Penalty. Here's the Playbook.

What actually changed — and why 2026 is the year it finally counts

Two separate rules are now in force at the same time, and confusing them is where people get hurt. Rule one is the 10-year rule: if you're a non-spouse beneficiary who inherited in 2020 or later, the entire account has to be emptied by December 31 of the 10th year after the original owner died. Rule two — the one that was on hold until now — is the annual RMD requirement: if the person you inherited from had already reached their required beginning date and was taking their own required minimum distributions, you must also take a distribution in each of years one through nine, not just clear the balance at the end.

From 2021 through 2024 the IRS repeatedly waived the penalty for skipping those interim withdrawals because the regulations were still in flux. The final regulations settled the question in favor of annual RMDs, made them effective for 2025, and offered no further relief for 2026. In plain terms: the years you may have been allowed to skip are behind you, the clock on your 10-year deadline never stopped ticking, and the annual withdrawals are now mandatory and penalized if missed.

First, figure out which kind of heir you are

The rules split sharply by who you are and when the original owner died. Run yourself through this list before you do anything else — it determines whether you're on the 10-year clock, whether you owe annual withdrawals, and whether you're exempt entirely.

The four beneficiary buckets

• Surviving spouse: You get the most flexibility and are NOT stuck with the 10-year rule. You can roll the IRA into your own, treat it as your own, or remain a beneficiary — in most cases you can keep stretching distributions over your own life expectancy.
• Non-spouse subject to the 10-year rule (the big group — adult children, most other relatives, friends): The account must be gone by year 10. If the original owner had already started their own RMDs, you also owe an annual withdrawal in years 1 through 9. If they died before starting RMDs, you can skip the interim withdrawals and take the money whenever you like inside the 10 years — but it still must be empty by year 10.
• Eligible designated beneficiaries (EDBs): A narrow protected class — minor children of the owner, disabled or chronically ill individuals, and anyone not more than 10 years younger than the deceased. EDBs can still stretch withdrawals over their own life expectancy instead of racing a 10-year clock.
• Minor child of the owner: Treated as an EDB and can stretch — but only until the age of majority (21). Once the child turns 21, the 10-year clock starts, so the account must be emptied by age 31.

The penalty for skipping a withdrawal is real — and stackable

If you're required to take an annual RMD and you don't, the IRS imposes an excise tax under Internal Revenue Code Section 4974 equal to 25% of the amount you should have withdrawn but didn't. On a $20,000 required distribution you skipped, that's a $5,000 penalty — for money you never even received.

There is a relief valve: SECURE 2.0 lets you knock the penalty down to 10% if you take the missed distribution and file Form 5329 (Part IX) within two years of the missed deadline. But that's a discount on a mistake, not a strategy. The cleaner move is to calculate the withdrawal correctly and take it on time — and if the account owner died on or after their required beginning date, assume an annual RMD is due unless a tax professional tells you otherwise.

The annual RMD math itself is mechanical: take the account's December 31 balance from the prior year and divide by your life-expectancy factor from the IRS Single Life Table for the year after the owner's death. In every year after that, you don't re-look up your age — you simply subtract 1 from the previous year's factor.

The bigger trap isn't the penalty — it's the year-10 tax bomb

Here's the mistake that costs far more than any missed-RMD penalty: doing the legal minimum, letting the balance ride, and then withdrawing everything in year 10. Because every dollar from a traditional inherited IRA lands on your tax return as ordinary income, a lump-sum withdrawal can rocket you into the top brackets for a single year.

Consider a $600,000 inherited traditional IRA. Pull it all out in one year and a large slice gets taxed at 32% to 37%, a mistake one analysis pegged at nearly $200,000 in federal tax. Now spread it: for 2026, a single filer stays in the 24% bracket up to $197,300 of taxable income, and the standard deduction is $15,000. Taking roughly $60,000 a year for 10 years, layered on top of a normal salary, keeps far more of the money in the 22% and 24% brackets instead of the 32%+ zone. On a $500,000 account, equal annual distributions of about $60,000 to $70,000 are dramatically more efficient than a single year-10 sweep — spreading the income can cut the total federal tax bill by tens of thousands of dollars.

The counterintuitive lesson: the annual-RMD requirement everyone is grumbling about is often doing you a favor. It forces you to smooth the income out instead of walking into a year-10 wall.

Your 2026 inherited-IRA action plan

• Pin down two dates: the year the original owner died (that sets your year-10 deadline) and whether they had already started their own RMDs (that decides if you owe annual withdrawals).
• If annual RMDs apply, calculate this year's using the prior-year December 31 balance and your Single Life Table factor — then take it before December 31 to avoid the 25% penalty.
• Don't default to the minimum. Model your taxable income for the whole 10-year window and aim to fill up your current bracket each year rather than dumping the balance in year 10.
• Use low-income years — a sabbatical, a gap between jobs, an early-retirement year before Social Security starts — to take larger voluntary distributions while your rate is low.
• Check whether it's a Roth inherited IRA: it's still subject to the 10-year emptying rule, but there are no annual RMDs and qualified withdrawals are tax-free, so you can let it grow untouched and take it all in year 10 with no tax cost.
• If you already missed a 2025 required distribution, take it now and file Form 5329 to cut the penalty from 25% to 10% before the two-year window closes.

A quick word of caution

Before you take a large distribution to 'get it over with,' run the numbers across all 10 years, not just this one. A single big withdrawal can push you into a higher bracket, trigger higher Medicare premiums (IRMAA), and phase you out of credits — costs that never show up on the withdrawal itself. Spreading the money out is usually the cheaper path, and an RMD calculator plus a tax projection will show you exactly where your bracket ceiling sits each year.
