Inherited IRA Rules 2026: The 10-Year Rule Is Now Fully in Effect

If you inherited an IRA from a parent, sibling, or anyone other than your spouse after January 1, 2020, the rules changed dramatically — and the IRS’s multi-year grace period is now over.

Starting in 2025, most non-spouse beneficiaries must begin taking annual required minimum distributions (RMDs) from inherited IRAs. In 2026, these rules are fully in effect with no further delays expected. Here’s what you need to know.

What Changed: The End of the Stretch IRA

Before the SECURE Act of 2019, inheriting an IRA was a powerful estate planning tool. A 40-year-old who inherited a parent’s IRA could “stretch” distributions over their own life expectancy — potentially 40+ years. The account kept growing tax-deferred, and the annual withdrawals were small enough to barely register as income.

The SECURE Act ended the stretch IRA for most beneficiaries. Congress replaced it with a 10-year rule: most non-spouse beneficiaries must empty the inherited account within 10 years of the original owner’s death.

What wasn’t clear for several years was whether beneficiaries had to take annual distributions during those 10 years, or could simply wait and take everything in year 10. The IRS finalized regulations in 2024 that answered this question — and the answer depends on whether the original owner had already started taking their own RMDs.

The Two Key Scenarios in 2026

Scenario 1: The original owner had NOT yet started RMDs

If the person you inherited from died before they were required to take RMDs (generally before age 73), you have maximum flexibility. You do not need to take annual distributions. You can withdraw any amount at any time during the 10-year window — including nothing for years and then everything at the end. The only requirement is that the account is fully emptied by December 31 of the 10th year after the owner’s death.

Scenario 2: The original owner HAD started RMDs

If the person you inherited from had already begun taking their own RMDs, you must:

1. Take annual RMDs during years 1 through 9, calculated using your own life expectancy
2. Empty the remaining balance by December 31 of year 10

Who Is Exempt From the 10-Year Rule

“Eligible designated beneficiaries” (EDBs) can still stretch distributions over their own life expectancy. You qualify as an EDB if you are:

• The surviving spouse of the IRA owner
• A minor child of the IRA owner (until age 21, then the 10-year rule kicks in)
• Disabled (as defined by the IRS)
• Chronically ill (as defined by the IRS)
• An individual no more than 10 years younger than the original account owner

How to Calculate Your 2026 RMD

If annual distributions are required, the calculation uses the IRS Single Life Expectancy Table:

1. Find your life expectancy factor using your age in the year after the owner died
2. Subtract one for each subsequent year
3. Divide your prior year-end account balance by that factor

Example: You were 55 when you inherited a traditional IRA in 2022 (owner had started RMDs). Your baseline life expectancy factor at age 56 was 30.6. For 2026 — year four — subtract 3, giving 27.6. With a $325,000 year-end 2025 balance:

$325,000 ÷ 27.6 = $11,775 required distribution

That amount is added to your ordinary income for the year. Combined with wages, Social Security, or other retirement income, it can push you into a higher bracket.

The Tax Trap Most Beneficiaries Miss

The 10-year rule creates a tax planning problem most people don’t see coming.

Inherit a $500,000 traditional IRA at age 50, during your peak earning years. You must withdraw the entire account over the next decade. If you delay and take the bulk in years 9 and 10, those withdrawals stack on top of your regular income and can easily push you into the 32% or 37% bracket.

The better approach is spreading withdrawals strategically — taking larger amounts in lower-income years (between jobs, before Social Security starts, before your own RMDs begin) and smaller amounts in higher-income years.

This is exactly what Fatboy Financial Planner is designed to model. You can project inherited IRA distributions alongside your own accounts, Social Security, and spending to find the lowest-tax withdrawal sequence.

What Happens If You Miss an RMD

The penalty is 25% of the amount you should have withdrawn, reducible to 10% if corrected within two years.

On a $400,000 inherited IRA with a required $15,000 distribution, missing it costs up to $3,750 in penalties — plus the income tax when you eventually withdraw. Neither penalty nor tax disappears. They stack.

Planning Strategies for 2026

If you have flexibility (owner died before starting RMDs):

• Withdraw in years when your income is lower
• Take larger distributions to fill lower tax brackets in lean years
• Avoid bunching large withdrawals into high-income years

If annual RMDs are required:

• You can always take more than the required minimum — just not less
• Watch Medicare IRMAA thresholds — large inherited IRA distributions raise your premiums two years later
• Coordinate with your own RMDs if you have a traditional IRA, since they compound the taxable income problem

What This Means for Your Own Estate Planning

If you have a traditional IRA and you’re thinking about what your heirs will face, the 10-year rule changes the math significantly.

Adult children inheriting a $600,000 traditional IRA face a decade of forced distributions likely taxed at their peak earning rates. A Roth IRA still passes through the 10-year rule — but qualified distributions are tax-free to your heirs.

The Bottom Line

In 2026, inherited IRA rules are clear and fully enforced:

• Most non-spouse beneficiaries must empty inherited accounts within 10 years
• If the original owner had started RMDs, annual distributions are required — no skipping years
• Penalties for missed distributions are up to 25%
• Strategic timing of withdrawals can save tens of thousands in taxes

The grace period is over. If you inherited an IRA after 2019 and aren’t sure what’s required, get clarity now — not after a penalty notice arrives.
