Inherited IRA Rules
When you inherit an IRA or other retirement account, the rules governing how you must take distributions — and how much tax you'll owe — depend heavily on your relationship to the deceased and whether the original owner had already started Required Minimum Distributions. The SECURE Act of 2019 fundamentally changed these rules, eliminating the "stretch IRA" strategy that allowed most beneficiaries to take distributions over their entire lifetime. Now, most non-spouse beneficiaries must empty inherited accounts within 10 years. IRS final regulations issued in 2024 clarified that if the original owner had already started RMDs, beneficiaries must take annual distributions during the 10-year period — not just one lump sum at the end. Failing to take required annual distributions triggers the 25% excise tax (10% if corrected within two years). Surviving spouses, minor children (until age 21), disabled beneficiaries, and people within 10 years of the deceased's age retain more favorable rules. For estate planning purposes, the shift from the lifetime stretch to the 10-year rule means inherited traditional IRAs can create substantial tax bunching for working-age children who inherit and must take distributions on top of their employment income. Inherited Roth IRAs still face the 10-year rule, but distributions are tax-free to the beneficiary — making Roth the superior inheritance vehicle.
Current Law (2026)
The SECURE Act (2019) fundamentally changed how inherited IRAs are distributed. Most non-spouse beneficiaries must empty inherited accounts within 10 years.
| Beneficiary Type | Distribution Rule |
|---|---|
| Surviving spouse | Can treat as own OR stretch over life expectancy |
| Minor child of deceased | Stretch until majority, then 10-year rule |
| Disabled/chronically ill | Life expectancy stretch |
| Not more than 10 years younger than deceased | Life expectancy stretch |
| All other beneficiaries | 10-year rule (empty by end of year 10) |
| Non-designated (estate, charity) | 5-year rule (if death before RMD age) or life expectancy of deceased |

How It Works
Under the 10-year rule enacted by the SECURE Act (2019), most non-spouse beneficiaries must withdraw the entire inherited account balance by December 31 of the 10th anniversary of the original owner's death. The IRS final regulations issued in July 2024 added a critical nuance: if the original owner had already started Required Minimum Distributions before death (had passed their Required Beginning Date), the beneficiary must also take annual distributions during years 1 through 9 — not simply wait until year 10 to take a lump sum. This "at least as rapidly" rule reinstates a modified stretch within the 10-year window when the owner had already been distributing. Annual distributions skipped during 2021–2024 were covered by IRS transition relief (no penalty), but the requirement applies in full starting 2025. A missed annual distribution triggers the 25% excise tax, reduced to 10% if corrected within two years.
Surviving spouses have three options unavailable to other beneficiaries: (1) Roll the IRA into their own IRA — treating it as their own account, following their own RMD schedule starting at their age 73, and naming their own beneficiaries; (2) Remain as a named beneficiary — taking distributions over their own life expectancy, essentially an unlimited stretch; or (3) Elect the 10-year rule (rarely the best choice). Rolling into the surviving spouse's own IRA is usually the better option for a younger surviving spouse who can defer distributions to their own RMD age. The exception: if the surviving spouse is under 59½ and may need the funds soon, remaining as a named beneficiary lets them take distributions penalty-free (beneficiary distributions avoid the 10% early withdrawal penalty). Many advisors recommend delaying the rollover election until after the surviving spouse's 59th birthday if funds might be needed before then.
Eligible Designated Beneficiaries (EDBs) retain the old lifetime stretch and don't face the 10-year rule. The five qualifying categories are: surviving spouses; minor children of the deceased (lifetime stretch until age 21, after which the 10-year rule activates on the remaining balance — grandchildren don't qualify); disabled individuals meeting IRS criteria; chronically ill individuals meeting IRS criteria; and beneficiaries not more than 10 years younger than the deceased (siblings, close friends, and others near the deceased's age).
Inherited Roth IRAs follow the same 10-year rule for most beneficiaries, but with one major advantage: distributions are income-tax-free to the beneficiary, since the original owner already paid tax on contributions and growth. Because Roth IRA owners are never required to take RMDs during their lifetime, the "at-least-as-rapidly" annual distribution requirement doesn't apply to inherited Roth accounts — the beneficiary can let the balance compound tax-free for the full 10 years and take a single tax-free distribution in year 10. This asymmetry with inherited traditional IRAs is the primary reason Roth conversions are the most effective estate planning tool for IRA holders leaving accounts to working-age heirs. Trust beneficiaries can qualify for EDB treatment through properly structured "see-through" trusts, but compressed trust tax brackets and complex drafting requirements make trust inheritance of retirement accounts an area requiring specialized estate planning counsel — see Trust and Estate Income Taxation.
How It Affects You
If you recently inherited a traditional IRA or 401(k) from a non-spouse (parent, sibling, friend): The SECURE Act replaced the "stretch IRA" with a 10-year rule for most non-spouse beneficiaries — you must empty the entire account by December 31 of the 10th year after the account owner's death. The missed-distribution penalty is 25% of the shortfall (reduced from 50% by SECURE 2.0), dropping to 10% if you correct within 2 years. The critical question your tax advisor must answer: did the original owner die before or after their Required Beginning Date (the date by which they had to start taking RMDs)? If they died before RMDs started, you have complete flexibility on timing within the 10 years — you can take it all in year 1, let it grow, or spread it evenly. If they died after RMDs started, the IRS's 2024 final regulations require you to take annual minimum distributions in years 1-9, then distribute the balance in year 10. (The IRS granted transition relief for 2021-2024, so skipped distributions in those years won't be penalized — but starting in 2025, the annual distribution requirement applies.) Tax planning strategy: map your expected income in each of the next 10 years and concentrate distributions in lower-income years to minimize the marginal tax hit.
If you are the surviving spouse of an IRA owner: Your options are more favorable than anyone else's. You can: (1) Roll the IRA into your own IRA — treating it as your own IRA, following your own RMD schedule starting at age 73, and naming your own beneficiaries; (2) Remain as beneficiary — taking distributions over your own life expectancy (essentially an unlimited stretch); or (3) Elect the 10-year rule (rarely optimal). The rollover into your own IRA is usually the best choice for a younger surviving spouse — it defers required distributions until you reach your own RMD age. However, if you're under 59½, be careful: rolling into your own IRA means any distribution before 59½ is subject to the 10% early withdrawal penalty, while remaining as beneficiary lets you take distributions as a beneficiary without penalty. The optimal choice often hinges on your age and whether you need income now. Consider delaying the rollover election until after your 59th birthday if you might need the funds soon. In either case, name new beneficiaries promptly — the inherited IRA's beneficiary designations affect your heirs' options.
If you're a disabled person, chronically ill person, or someone within 10 years of age of the deceased account owner: You qualify as an "eligible designated beneficiary" (EDB) under the SECURE Act's exceptions to the 10-year rule, allowing you to stretch distributions over your own life expectancy — potentially decades — rather than emptying the account in 10 years. Disabled and chronically ill status must meet IRS definitions (generally: unable to engage in substantial gainful activity due to physical or mental impairment, or requiring substantial care). The "not more than 10 years younger" exception applies to siblings, friends, or others close in age to the deceased. If you qualify as an EDB, the stretch approach generates smaller annual distributions that are typically taxed at a lower rate than a compressed 10-year schedule, and the account continues growing tax-deferred for longer. Minor children of the deceased also qualify as EDBs — but only until they reach age 21 (or state age of majority if later), after which the 10-year clock starts running on the remaining balance. Grandchildren and other minor heirs generally do not qualify for EDB treatment.
If you're doing estate planning to protect your heirs from the 10-year tax hit: The most powerful strategy is the pre-death Roth conversion — converting your traditional IRA to Roth IRA over several years before death, paying the income tax yourself at your current (hopefully lower) rate. Your heirs still face the 10-year rule, but they can take the distributions income-tax-free, because Roth distributions carry no income tax obligation. This is particularly attractive if you're in a low tax bracket between retirement and RMD onset, or if your heirs are high earners who would face the distributions at 32-37% marginal rates. For IRAs designated to charity: a charity doesn't pay income tax on IRA distributions, so naming a charity as beneficiary eliminates the income tax entirely — while leaving other assets (with a stepped-up cost basis) to your heirs. If you're naming multiple beneficiaries, have them establish separate inherited IRA accounts by December 31 of the year after your death — this allows each beneficiary to take distributions on their own schedule and potentially qualify independently for EDB status. Large IRAs can also face federal estate tax exposure on top of income tax — the two-tax problem for high-net-worth families that makes lifetime Roth conversions particularly valuable. Note that while most appreciated assets get a step-up in basis at death, traditional IRAs do not — beneficiaries inherit the original tax liability.
State Variations
Inherited IRA distribution rules are federal. State tax treatment of distributions follows the state's normal retirement income rules. Some states exempt all or part of inherited retirement distributions from state income tax.
Implementing Regulations
Inherited IRA distribution rules are implemented through 26 CFR SS 1.401(a)(9)-4 through 1.401(a)(9)-9 (designated beneficiary rules, required minimum distributions for beneficiaries). The SECURE Act and SECURE 2.0 Act provisions are being implemented through proposed Treasury regulations.
Pending Legislation (119th Congress)
- Stretch IRA restoration: Multiple proposals in each recent Congress have sought to repeal or narrow the 10-year rule. None have advanced in the 119th Congress, but the idea resurfaces in every tax reform negotiation as a potential offset or sweetener.
- SECURE 2.0 technical corrections: Treasury is still issuing guidance on SECURE 2.0 provisions affecting inherited IRAs, including the interaction between Roth employer plan accounts and inherited IRA distribution rules. Technical corrections legislation may clarify edge cases.
- Annual RMD requirement during 10-year period: The IRS final regulations (2024) requiring annual distributions when the original owner had begun RMDs remain controversial. Some lawmakers have proposed overriding this administratively complex requirement via legislation, but no standalone bill has advanced.
Recent Developments
- IRS final regulations (July 2024): After three years of proposed rules and transition relief, the IRS finalized regulations confirming that non-spouse beneficiaries subject to the 10-year rule must take annual RMDs during years 1-9 if the original account owner had already begun required distributions. This ends the uncertainty that existed since the SECURE Act passed in 2019. Beneficiaries who skipped annual distributions during 2021-2024 under IRS transition relief will not be penalized for those years.
- Penalty reduction (SECURE 2.0): The excise tax for missed RMDs dropped from 50% to 25% (10% if corrected within two years) under SECURE 2.0. This applies to inherited IRA distributions as well, reducing the sting of a missed annual distribution — though the year-10 deadline remains absolute.
- Roth conversion planning surge: Financial advisors report increased interest in pre-death Roth conversions as a strategy to shield heirs from the 10-year income tax hit. The logic: pay tax now at your rate so heirs receive tax-free Roth distributions within the 10-year window. This is particularly attractive for retirees in lower tax brackets before Social Security and RMDs push them higher.
- TCJA/OBBBA extension and the Roth conversion window (2025-2026): The One Big Beautiful Bill Act (OBBBA) extends TCJA's individual income tax rates, keeping current tax brackets (including the 22-24% brackets for middle-income earners) in place rather than allowing them to revert to higher pre-TCJA rates. This changes the Roth conversion calculus: if higher future tax rates were the driving fear, OBBBA's extension reduces (but does not eliminate) that urgency. Roth conversions still benefit heirs in the 10-year distribution window by removing inherited IRA income inclusion. IRS enforcement of the 10-year rule inherited IRA RMD obligations has begun now that final regulations are in effect; beneficiaries who have not taken annual distributions (for accounts where the decedent had begun RMDs) need to calculate and take 2025 annual distributions to avoid the 25% excise tax.
