If you inherited an IRA from a parent or relative after 2019, you're subject to one of the most misunderstood rules in retirement planning: the SECURE Act 10-year rule. Get it wrong and the IRS penalty is steep. Plan it poorly and you can push yourself into tax brackets you never needed to visit.
Here's what the rule actually requires — and the withdrawal strategies that keep more of the money in your family.
The 10-Year Rule in Plain English
Before 2020, beneficiaries could "stretch" inherited IRA withdrawals over their own lifetime — decades of tax-deferred growth. The SECURE Act ended that for most people.
The rule today: if you inherit an IRA from someone other than your spouse, you generally must empty the entire account by December 31 of the 10th year after the original owner's death.
And there's a second layer many people miss: if the original owner had already started required minimum distributions (RMDs), you must also take annual RMDs in years 1–9 — not just drain it by year 10. The IRS confirmed this requirement, and missing an RMD carries a 25% excise tax on the amount you should have withdrawn (reduced to 10% if corrected promptly).
Who's Exempt: Eligible Designated Beneficiaries
The 10-year rule does not apply to:
| Beneficiary | What they get instead |
|---|---|
| Surviving spouse | Can roll it into their own IRA and treat it as theirs |
| Minor child of the owner | Life-expectancy payouts until age 21, then the 10-year clock starts |
| Disabled or chronically ill individuals | Lifetime stretch remains available |
| Beneficiary less than 10 years younger (e.g., a sibling) | Lifetime stretch remains available |
Everyone else — adult children, grandchildren, nieces, nephews, friends — is on the 10-year clock.

Every dollar withdrawn from an inherited traditional IRA is ordinary income in the year you take it. That creates the trap:
Example: You inherit a $500,000 traditional IRA at age 52, in your peak earning years, making $120,000. If you wait and take the whole $500,000 in year 10, that year's income is $620,000 — deep into the top brackets. A large chunk of your inheritance goes straight to the IRS.
Spread the same $500,000 evenly at $50,000/year, and each withdrawal is taxed on top of $120,000 — mostly in the 24% bracket instead of 35–37%. The difference can exceed $50,000 in tax on the same inheritance.
Four Smarter Withdrawal Strategies
1. Level withdrawals (the default)
Divide the balance by remaining years and withdraw evenly. Simple, and it prevents the year-10 bracket spike. A good baseline for most beneficiaries.
2. Fill your bracket, not more
Each year, withdraw just enough to reach the top of your current tax bracket and stop. In lower-income years, take more; in bonus years, take the minimum. This requires paying attention annually, but it's the most tax-efficient approach for people with variable income.
3. Front-load in low-income years
Between jobs? Retired early but not yet claiming Social Security? Those low-income "gap years" are golden windows to take larger inherited IRA withdrawals at 10–12% rates.
4. Coordinate with your own retirement timeline
If you'll retire within the 10-year window, consider taking smaller withdrawals while working and larger ones after retirement, when your salary disappears and your bracket drops.
Inherited Roth IRA? Different game: the 10-year rule still applies, but withdrawals are tax-free — so the optimal move is usually the opposite: leave it growing untouched until year 10, then take it all.
Don't Plan the Inherited IRA in Isolation
Here's the mistake even careful planners make: optimizing the inherited IRA by itself while ignoring how it interacts with everything else — Roth conversions, capital gains harvesting, Medicare IRMAA surcharges, and Social Security taxation. An extra $40,000 of inherited IRA income can make more of your Social Security taxable and trigger higher Medicare premiums two years later.
This is exactly the kind of multi-account puzzle RetirePro was built for. Add your inherited IRA balance in the planner, and it's factored into your total wealth projection and Monte Carlo analysis alongside your 401(k), Roth, and taxable accounts. Premium members can then ask the AI Retirement Advisor questions like "What's the most tax-efficient way to empty my inherited IRA before 2034?" — and get an answer grounded in your actual balances, tax settings, and retirement timeline.
Action Checklist
- Confirm your category — spouse, eligible designated beneficiary, or 10-year rule
- Check the RMD sub-rule — if the original owner was past their RMD start age, you need annual withdrawals in years 1–9
- Map your 10-year income forecast — where are your low-tax windows?
- Choose a strategy — level, bracket-fill, or front-load
- Model it — add your inherited IRA to your RetirePro plan and see how each strategy affects your long-term success rate
An inheritance is a gift. Don't let a preventable tax mistake shrink it.
