Inherited IRA Distribution Rules: What Beneficiaries Must Know

How Inherited IRA Distributions Actually Work After the SECURE Act

The rules for taking money out of an inherited IRA changed dramatically when the SECURE Act took effect in 2020, and the IRS didn't finalize the regulations until July 2024. That three-year gap created mass confusion — and the stakes are real. Miss a required distribution, and you face a 25% excise tax on whatever you should have withdrawn.

Here's the framework that matters: the IRS divides beneficiaries into three categories, and the distribution rules depend entirely on which category you fall into.

Eligible Designated Beneficiaries (EDBs) — surviving spouses, disabled or chronically ill individuals, minor children of the deceased (under 21), and people not more than 10 years younger than the account owner — still get the old "stretch" option. They can take distributions over their own life expectancy.

Designated Beneficiaries — most adult children, siblings, friends — must empty the account within 10 years of the owner's death. And if the original owner had already reached their Required Beginning Date (age 73 for those born in 1951–1959, or 75 for those born after 1959), annual RMDs are mandatory in years 1 through 9.

Non-Designated Beneficiaries — estates, charities, certain trusts — face either the 5-year rule or must take distributions over the deceased owner's remaining life expectancy, depending on whether the owner died before or after their RBD.

Calculating Your Annual Distribution

An inherited IRA RMD calculator works differently than a standard RMD calculator. The key variable is the IRS Single Life Table, not the Uniform Lifetime Table used by original account owners.

For a designated beneficiary taking annual distributions under the 10-year rule: divide the prior year's December 31 account balance by your life expectancy factor from the Single Life Table, reducing that factor by 1.0 each subsequent year. In year 10, whatever remains must come out.

For EDBs using the stretch, annual RMDs are based on their own single life expectancy under the Single Life Table.

The year-of-death RMD adds another wrinkle. If the original owner died after their RBD and hadn't yet taken their full RMD for that year, the beneficiary must complete it by December 31 of the year of death. The 25% penalty applies to any shortfall — though the SECURE 2.0 Act reduced it from the old 50%, and a correction within two years drops the penalty further to 10%.

Roth IRA Distributions: Different Tax Treatment, Same Timeline

Inherited Roth IRAs follow the same 10-year depletion timeline for non-EDBs, but distributions come out tax-free. The strategic difference: since there's no tax cost to withdrawing, there's less reason to defer. But there's also no RMD requirement in years 1 through 9, even if the original owner had reached their RBD, because Roth IRAs never have RMDs during the owner's lifetime.

The account must still be fully emptied by December 31 of the tenth year.

When the IRS Waiver Ends

The IRS waived penalties for missed annual RMDs within the 10-year window for tax years 2021 through 2024. That grace period is over. Starting with the 2025 tax year, annual distributions are mandatory for beneficiaries of owners who died on or after their RBD.

If you inherited an IRA in 2020 or 2021 and haven't been taking annual distributions, you need to start now or face the excise tax.

Protect the Inherited Assets

Distribution timing directly affects your tax bracket. A strategic plan — spreading distributions across the full 10-year window instead of taking a lump sum in year 10 — can save thousands in income tax. The complete retirement account claims toolkit includes year-by-year distribution worksheets and tax-bracket modeling to help you map this out.

Getting the distribution math right isn't optional — it's the difference between keeping more of the inheritance and handing a quarter of it to the IRS as a penalty.
