TL;DR — Quick Verdict
- Most non-spouse beneficiaries must empty an inherited IRA by December 31 of the 10th year after death — the SECURE Act “10-year rule,” now enforced since 2025.
- If the original owner had already started RMDs, you also owe annual required minimum distributions in years 1 through 9, then a full cleanout in year 10.
- A $500,000 traditional inherited IRA emptied in one lump sum can push a married couple into the 35% bracket and cost roughly $60,000–$130,000 more in federal tax than spreading it over 10 years.
- Missing a required distribution triggers a 25% excise tax on the shortfall, dropping to 10% if you fix it within two years and file IRS Form 5329.
- Recommendation: model your bracket year by year and spread withdrawals deliberately — the default of “wait until year 10” is usually the most expensive choice.
Roughly 10 million Americans will inherit a retirement account over the next two decades, and most of them will hand the IRS more than they need to. The reason is a rule change almost no one planned for: the SECURE Act of 2019 killed the “stretch IRA,” and the IRS finalized the replacement rules — T.D. 10001 — on July 19, 2024, with full enforcement beginning in 2025. Under the old system, a 45-year-old who inherited a parent’s IRA could stretch withdrawals across a 38-year life expectancy, keeping most of the balance growing tax-deferred. Under current rules, that same person has 10 years to drain the account, and every dollar of a traditional IRA lands as ordinary income. This guide shows exactly what the 10-year rule requires, when annual distributions are mandatory, and how much the timing of your withdrawals actually costs — with dollar-figure scenarios modeled against the 2026 federal brackets. Fidelity and Vanguard, the two largest IRA custodians, both now warn beneficiaries about the 25% penalty for getting it wrong. The mechanics reward planning and punish autopilot.
What the 10-Year Rule Actually Requires in 2026
The SECURE Act divided everyone who inherits an IRA into two camps. Eligible designated beneficiaries — surviving spouses, minor children of the owner (until age 21), disabled or chronically ill individuals, and anyone not more than 10 years younger than the deceased — can still stretch distributions over their own life expectancy. Everyone else, the group the IRS calls non-eligible designated beneficiaries, falls under the 10-year rule. In practice that means most adult children, grandchildren, nieces, nephews, and friends named on an account.
Here is the trap that surprised the most people. The 10-year clock starts the year after death and never resets. Inheriting in 2021 did not grant a fresh decade beginning in 2025 — the deadline is still December 31, 2031. And whether you owe distributions along the way depends entirely on one fact: had the original owner already reached their required beginning date and started taking their own RMDs?
When the owner died before starting RMDs, you have flexibility. You can skip years, take uneven amounts, or wait — as long as the account hits zero by the end of year 10. When the owner died on or after their required beginning date, the IRS final regulations require an annual RMD in each of years 1 through 9, with the remainder cleaned out in year 10. Understanding your cost basis step-up at death matters for other inherited assets, but note it does not apply to traditional IRAs — those carry the decedent’s untaxed deferral straight to you.
The Real Tax Cost: Lump Sum vs. Spreading It Out
Timing is where beneficiaries win or lose the most money. Because a traditional inherited IRA is taxed as ordinary income, the size of each year’s withdrawal decides your marginal bracket. Consider a married couple filing jointly with $120,000 of their own taxable income who inherit a $500,000 traditional IRA from a parent who had already started RMDs.
Modeled by the author using 2026 married-filing-jointly brackets: 22% band to $211,400 and 35% band to $768,700. Bracket thresholds sourced from IRS Rev. Proc. 2025-32, via Tax Foundation (verify at taxfoundation.org). Tax figures are illustrative estimates on the IRA portion only.
The gap between the worst and best approach here exceeds $37,000 — and it widens for larger accounts or higher earners. Pile the entire $500,000 on top of $120,000 of existing income and roughly $145,000 of it gets taxed at 32% or 35%. Spread across a decade, most of that same money stays inside the 22% and 24% bands. The couple’s own income, expected raises, and any planned tax implications of selling inherited property in the same window all feed into which year to lean on.
What Determines Your Required Annual Distribution
When annual RMDs apply, the amount is not arbitrary. Divide the prior-year-end account balance by the life expectancy factor from the IRS Single Life Table for your age in the first distribution year, then subtract one from that factor each subsequent year. A 52-year-old with a factor near 34.3 on a $400,000 balance owes about $11,660 in year one — a manageable figure that rises as the divisor shrinks.
Picture a concrete case. Maria, 55, inherits a $600,000 traditional IRA in 2026 from her father, who was 78 and long past his required beginning date. She owes an annual RMD each year from 2026 through 2035, then must zero the account by December 31, 2036. Her year-one RMD runs roughly $18,600, but because the 10-year cleanout looms, taking only the minimum leaves a large taxable balloon at the end. Maria’s smarter move is to withdraw well above the minimum in her lower-income years, flattening the final-year spike. The annual RMD is a floor, not a ceiling — and treating it as the target is the single most common way beneficiaries overpay.
10-Year Cleanout vs. Spousal Rollover: Which Is Better?
A surviving spouse is the one beneficiary who escapes the 10-year rule entirely, and the choice between treating the account as your own versus keeping it as an inherited IRA carries real money. Rolling the account into your own IRA lets you name new beneficiaries, delay RMDs until your own required beginning date, and stretch tax-deferred growth for years. Keeping it as an inherited IRA lets a younger spouse tap the funds before age 59½ without the 10% early-withdrawal penalty.
Compare a 62-year-old widow with no income pressure against a 48-year-old widower who needs access. The older spouse rolling $700,000 into her own IRA defers all tax until 73, letting the balance compound and spreading eventual RMDs across her full life expectancy. The younger spouse, by contrast, benefits from inherited-IRA status precisely because he can pull funds penalty-free at 48.
Verdict
For a surviving spouse over 59½ who does not need immediate income, the spousal rollover wins — it maximizes deferral and avoids the compressed 10-year timeline entirely. For a spouse under 59½ who needs access to the money, keep it as an inherited IRA to sidestep the early-withdrawal penalty, then roll it into your own IRA later once you pass 59½. Non-spouse beneficiaries do not get this choice; the 10-year rule is mandatory.
What Most People Get Wrong About Inherited IRAs
Three mistakes account for the majority of avoidable losses, and each carries a specific, quantifiable consequence.
Mistake 1: Assuming “10 years” means “wait until year 10.” The consequence is a single-year income spike that can double your effective tax rate on the account. The correct action is to withdraw during your lowest-income years — often a gap year, early retirement, or a period between jobs — and to fill your current bracket up to its ceiling rather than letting the balance snowball. Beneficiaries weighing this alongside broader probate avoidance strategies should coordinate the two, since IRAs pass outside probate by beneficiary designation.
Mistake 2: Forgetting the year-of-death RMD. If the original owner was due an RMD in the year they died and had not yet taken it, the beneficiary must. Under current guidance, taking that distribution by December 31 of the year after death avoids the excise penalty. Skip it and you inherit the owner’s shortfall along with the tax.
Mistake 3: Cashing out immediately out of fear. A panicked lump-sum withdrawal is the costliest reaction to inheriting an account. The correct action is to move the funds into a properly titled inherited IRA — “[Deceased], deceased, for the benefit of [You]” — which preserves your right to spread distributions. Retitling incorrectly, or moving cash into your own account, can be treated as a full taxable distribution with no undo. This intersects with broader creditor claim priority before heir distributions when an estate is still open.
The Penalty for Getting It Wrong
Miss a required distribution and the IRS charges a 25% excise tax on the shortfall — the difference between what you were required to withdraw and what you actually took. SECURE 2.0 cut this from the old 50% rate, effective for tax years after 2022, but 25% still stings. On a missed $20,000 RMD, that is a $5,000 penalty on top of the ordinary income tax you still owe once you take the distribution.
The relief valve is the two-year correction window. Take the missed amount and file IRS Form 5329 within two years of the original deadline, and the penalty drops automatically to 10% — $2,000 instead of $5,000 on that same shortfall. File Form 5329 with a reasonable-cause explanation and the IRS can waive the penalty entirely, which it has historically granted for honest, promptly corrected mistakes.

Who Should Withdraw Early, and Who Should Wait?
The right strategy hinges on your income trajectory across the 10-year window. Withdraw early and aggressively if you expect your income to rise — a beneficiary in their peak earning years who anticipates promotions, or one planning to retire before the 10-year deadline, should front-load withdrawals into currently lower-taxed years. Someone inheriting at 60 who plans to retire at 65 has a five-year window of lower income to exploit before Social Security and other RMDs stack up.
Wait, or spread evenly, if your income is stable and moderate and no single year offers a meaningful bracket advantage. In that case, an even 10-year split minimizes the peak marginal rate. And withdraw strategically around one-time events: a year with large deductions, a business loss, or a low-income gap is the year to take an oversized distribution. The one universally wrong answer is doing nothing until year 10. That path guarantees the largest possible single-year income spike and, for many families, tens of thousands in avoidable tax. If the broader estate is still winding through court, the probate duration by state and complexity may affect when you can even retitle the account, so start the clock on planning early.
Frequently Asked Questions
Do I have to take money out every year, or just by year 10?
It depends on whether the original owner had started their own RMDs. If they died on or after their required beginning date, the IRS final regulations require annual RMDs in years 1 through 9, then a full cleanout in year 10. If they died before starting RMDs, you can withdraw on any schedule as long as the account is empty by December 31 of the 10th year after death.
What is the penalty if I miss a required distribution?
The excise tax is 25% of the shortfall — the amount you should have withdrawn but didn’t. Under SECURE 2.0, that drops to 10% if you correct the missed distribution and file IRS Form 5329 within two years of the deadline. The IRS may also waive the penalty entirely if you show reasonable cause and correct the mistake promptly.
Does the 10-year rule apply to inherited Roth IRAs?
Yes, the 10-year cleanout applies to most non-spouse beneficiaries of Roth IRAs inherited after 2019 — the account must be emptied by the end of the 10th year. The key advantage is that qualified Roth distributions are tax-free, so there is no ordinary-income tax cost to timing. Most planners advise letting a Roth grow tax-free for the full 10 years, then withdrawing in year 10.
Can I roll an inherited IRA into my own IRA?
Only a surviving spouse can. Spouses may treat the inherited account as their own, gaining full deferral until their own required beginning date. Non-spouse beneficiaries cannot roll the funds into a personal IRA — doing so is treated as a full taxable distribution. Non-spouses must keep the account as a properly titled inherited IRA to preserve the ability to spread distributions.
How We Researched This Article
The distribution rules in this article are drawn directly from the IRS and Treasury final regulations on inherited retirement account RMDs (T.D. 10001), released July 19, 2024, with enforcement beginning in 2025. We cross-referenced the regulatory framework against analysis from the Kitces.com breakdown of the final regulations and reporting from Kiplinger’s Tax Letter to confirm the eligible-designated-beneficiary categories and the treatment of pre-2025 waived distributions.
All tax-cost scenarios were modeled by the author using the 2026 federal income tax brackets published by the IRS in Revenue Procedure 2025-32, with bracket thresholds verified against the Tax Foundation 2026 bracket tables. Penalty figures reflect the SECURE 2.0 Act’s reduction of the missed-RMD excise tax to 25% (10% if timely corrected), confirmed against Fidelity’s guidance on fixing a missed RMD.
