Inherited IRA 10-Year Rule 2026: What Non-Spouse Beneficiaries Actually Owe
How the inherited IRA 10-year rule works in 2026 — annual RMDs, the eligible designated beneficiary exceptions, and moves that minimize the tax bill.
A parent passes away and leaves you a $340,000 traditional IRA. The brokerage helpfully splits it into a new “Inherited IRA” account in your name and tells you “you have ten years to drain it.” For five years you assume that means one lump sum at the end. Then you read a piece in 2026 noting that the IRS finalized the annual RMD requirement during the 10-year window — and suddenly the question is whether you’ve been silently underpaying for years. Welcome to the inherited IRA 10-year rule in its 2026 form, where the simple “ten years” headline hides a complicated set of withdrawal mechanics.
This piece walks through how the inherited IRA 10-year rule actually works in 2026 — who’s covered, who’s exempt, the annual RMD requirement that confused everyone for years, and the four planning moves that minimize the tax bill on inherited retirement money.
What’s Happening: The 2026 Final Rules
The SECURE Act of 2019 replaced the old “stretch IRA” with the 10-year rule: most non-spouse beneficiaries who inherit an IRA must fully distribute the account within 10 years of the original owner’s death. SECURE 2.0 (2022) and subsequent IRS final regulations (issued in 2024 and refined into 2026) clarified two critical pieces:
- Annual RMDs are required during the 10-year window if the deceased had already started taking RMDs.
- The IRS waived enforcement of those annual RMDs for tax years 2021–2024 due to confusion. Starting 2025 and forward, annual RMDs are enforced.
Translated: in 2026, you must take an annual RMD and zero the account by the end of year 10. Missing the annual RMD now triggers a 25% excise tax on the shortfall (down from 50% pre-SECURE 2.0).
Inherited IRA: Who Owes What in 2026
| Beneficiary Type | Annual RMD Required? | 10-Year Zero-Out? | Stretch Allowed? |
|---|---|---|---|
| Spouse (own rollover) | Treats as own IRA — RMD at 73 | No | N/A |
| Non-eligible: decedent died after RBD | Yes (Single Life Table) | Yes | No |
| Non-eligible: decedent died before RBD | No | Yes (flexible timing) | No |
| Minor child (until majority) | Yes (life expectancy) | Starts at majority, then 10-yr clock | Partial |
| Disabled / chronically ill | Yes (life expectancy) | No | Yes (full stretch) |
| Within 10 years of decedent’s age | Yes (life expectancy) | No | Yes (full stretch) |
| Inherited Roth IRA (non-spouse) | No | Yes | No |
| Missed RMD penalty | 25% excise tax (10% if corrected within 2 years + Form 5329) | — | — |
Deep Dive: Who’s Covered, Who’s Exempt
The Default: Non-Eligible Designated Beneficiaries
Most adult children and unrelated heirs are non-eligible designated beneficiaries. They’re subject to the full 10-year rule with annual RMDs if the original owner died on or after their required beginning date (RBD — generally age 73 in 2026 under SECURE 2.0).
If the original owner died before their RBD, the 10-year rule still applies — but no annual RMD is required during the 10 years. You just have to zero the account by year 10.
This subtle split matters enormously for tax planning. Year of death + age of decedent = your withdrawal regime.
The Exempt Categories: Eligible Designated Beneficiaries (EDBs)
Five categories escape the 10-year rule and can use the older “stretch” pattern (life expectancy distributions):
- Surviving spouses (with additional spousal options including rollover into their own IRA).
- Minor children of the decedent — until they reach majority, then the 10-year clock starts.
- Disabled individuals under IRS definitions.
- Chronically ill individuals under IRS definitions.
- Beneficiaries not more than 10 years younger than the decedent (e.g., siblings close in age).
These five categories can take RMDs over their own life expectancy, similar to the pre-2020 stretch IRA.
Roth IRAs: Different Rules, Same Idea
Inherited Roth IRAs are also subject to the 10-year rule for non-spouse beneficiaries. The difference: distributions are tax-free as long as the original Roth IRA was at least 5 years old. There’s no annual RMD requirement during the 10-year window for inherited Roth IRAs since Roth owners themselves don’t have RMDs during life.
What It Means For You
Three scenarios frame the inherited IRA 10-year rule decision in 2026:
- You inherited a traditional IRA from a parent who was already taking RMDs: you owe annual RMDs (calculated from the IRS Single Life Table) plus a year-10 zero-out. Plan distributions across all 10 years to spread the tax hit, ideally pulling more in your lower-income years.
- You inherited from someone who died before their RBD: no annual RMD requirement, just the year-10 zero-out. You have full flexibility to time withdrawals around your tax brackets.
- You inherited a Roth IRA: no annual RMDs during the 10 years, and final distribution is tax-free. The optimal strategy is usually to let it grow as long as possible and withdraw the full balance in year 10.

Action Steps
- Confirm the date of death and whether the decedent had reached their required beginning date for RMDs. This determines whether annual RMDs apply during your 10-year window.
- Open an “Inherited IRA” account at the same brokerage if you haven’t. Do not roll an inherited IRA into your own IRA — that triggers full immediate taxation.
- Calculate the annual RMD using the IRS Single Life Expectancy Table based on your age in the year after the decedent’s death, reduced by one each subsequent year.
- Take the missed RMDs for 2025 onward if you haven’t been. The 2021–2024 waivers expired; missing 2025+ triggers the 25% excise tax (which can be reduced to 10% if corrected within 2 years and Form 5329 is filed).
- Plan distributions across the 10 years. Pull more in low-income years (sabbaticals, between jobs, retirement). Don’t let the year-10 forced zero-out land in your highest-bracket year.
- Consider charitable giving with Qualified Charitable Distributions (QCDs) if you’re 70½+ — direct charity transfers from inherited IRAs satisfy RMDs and avoid income inclusion.
- File Form 5329 with your tax return for any year you missed an RMD, requesting waiver of the excise tax. The IRS routinely grants waivers for first-time mistakes when corrected promptly.

FAQ
Can I just take it all out in year 10?
Yes, if no annual RMD is required (decedent died before RBD) — but you’d be stacking 10 years of growth into one tax year, almost certainly pushing yourself into a much higher bracket. Spreading withdrawals over the 10 years usually beats a year-10 lump sum even if your income today is high.
What if the decedent was already mid-RMD when they died?
You must finish the year-of-death RMD if it wasn’t completed before death. From the next year forward, you take RMDs based on your age (using the Single Life Table). The 10-year window starts the year after death.
How does this interact with my own retirement accounts?
Inherited IRAs are separate from your own IRAs for RMD purposes. Distributions from an inherited IRA do not satisfy RMDs on your own IRAs and vice versa.
What happens if I inherit and then die before year 10?
The successor beneficiary inherits the remaining 10-year window, not a fresh 10-year clock. They must zero the account by the original year-10 deadline.
Can I convert an inherited Traditional IRA to Roth?
No. Roth conversions are limited to your own IRAs. Inherited IRAs cannot be converted. The dollars are stuck in the traditional regime — you can only manage when to withdraw to optimize tax bracket impact.
Bottom Line
The inherited IRA 10-year rule in 2026 is no longer the simple “ten years to drain it” headline of 2020. Annual RMDs are now enforced for most non-spouse beneficiaries inheriting from a decedent who was past their required beginning date. Confirm your category (eligible designated vs non-eligible designated), calculate the annual RMD, and plan distributions across the 10 years to manage the tax bracket impact. Don’t let the year-10 deadline land all the income in your highest-earning year.
