Can a Beneficiary Less Than 10 Years Younger Stretch an IRA? (w/Examples) + FAQs

This article reflects federal rules and general state treatment as of June 2026 and covers tax year 2025 and the 2026 filing season. Tax law changes — confirm current figures with the IRS or a licensed professional before you act.

Quick Answer

Yes. For 2025 and 2026, a beneficiary who is not more than 10 years younger than the deceased IRA owner — including anyone older — qualifies as an Eligible Designated Beneficiary. They can skip the 10-year rule and “stretch” withdrawals over their own single life expectancy, taking smaller annual amounts.

Why This One Age Gap Matters So Much

When someone inherits an IRA from a person who was not their spouse, the federal government usually forces them to empty the account within 10 years. But there is a narrow group of heirs who escape that clock entirely. If you are not more than 10 years younger than the person who died — say a sibling four years your senior, a same-age partner, or an older friend — you fall into a protected class called an Eligible Designated Beneficiary, and you may stretch withdrawals across your whole life expectancy. That difference can mean keeping money growing tax-deferred for 30 or 40 more years instead of 10.

The stakes climbed sharply in 2025. The IRS issued final regulations on July 18, 2024 that ended years of confusion and began enforcing missed-distribution penalties. According to Fidelity’s analysis of the SECURE Act, missing a required withdrawal can trigger a 25% excise tax on the amount you should have taken — one of the steepest penalties in the tax code. Knowing whether you qualify for the stretch, and then taking the right amount on time, is now a real-money, real-deadline decision.

Breaking Down the “Not More Than 10 Years Younger” Rule

The SECURE Act of 2019 replaced the old “stretch IRA” — which let almost any heir spread withdrawals over a lifetime — with a default 10-year payout for most non-spouse beneficiaries. But Congress carved out five protected groups, called Eligible Designated Beneficiaries (EDBs), who keep the lifetime stretch. The “not more than 10 years younger” beneficiary is one of those five groups.

The test is simple to state and easy to get wrong. The beneficiary must be no more than 10 years younger than the IRA owner. Anyone older than the owner automatically passes. So does someone the same age, someone a few years younger, and someone up to a full 10 years younger. The moment the gap crosses 10 years and one day, the person loses EDB status and falls back to the 10-year rule.

This category exists for the people the old stretch was really meant to protect: siblings, life partners who never married, close friends, and other near-peers. It is the only EDB category that has nothing to do with marriage, disability, illness, or being a child of the owner. It is purely about age.

How the Age Gap Is Actually Measured

The gap is measured by actual birth dates, not by calendar year. As Key Private Bank explains the EDB test, you must use the real ages of the decedent and the beneficiary — not just the years they were born. This catches many people off guard.

Here is what that means in practice. Imagine the owner was born in January 2026 terms as age 70, and the beneficiary was born in a year that makes them appear “10 years younger” on paper. If the beneficiary’s birthday makes the true gap 10 years and 2 months, they fail. If it is 9 years and 11 months, they pass. The consequence of a miscount is severe: a person who wrongly assumes they qualify could skip the large annual withdrawals the 10-year rule sometimes requires and rack up penalties.

A common misconception is that “10 years younger” means “born 10 calendar years later.” It does not. What you should do: pull both birth certificates or the dates the IRA custodian has on file, calculate the exact difference in years and months, and keep that documentation with your records in case the IRS asks.

What “Stretch” Means for This Group

For a qualifying beneficiary, “stretch” means taking annual Required Minimum Distributions (RMDs) based on your own single life expectancy, starting the year after the owner dies. You do not have to empty the account in 10 years. You spread it across decades, and the balance keeps growing tax-deferred the whole time.

The annual amount is small in the early years and rises slowly. You find your life expectancy factor on the IRS Single Life Expectancy Table, divide the prior year-end balance by that factor, and that is your minimum. Each later year, you subtract 1.0 from the factor — a method called the “fixed-term” or “subtract one” rule.

The consequence of choosing the stretch wisely is powerful: more years of tax-deferred growth and smaller taxable bites each year, which can keep you in a lower tax bracket than a forced 10-year drawdown would.

Which Situation Applies to You?

The right answer depends entirely on who you are relative to the person who died. Use this to find your category before you do any math.

You are the surviving spouse — you have the most options, including treating the IRA as your own. The “10 years younger” rule does not concern you; see a spouse-beneficiary guide.
You are not more than 10 years younger than the owner (or older) — you are an EDB and may stretch over your life expectancy. This article is for you.
You are more than 10 years younger and not disabled, chronically ill, or a minor child of the owner — you are a “designated beneficiary” stuck with the 10-year rule.
You are the owner’s minor child — you are an EDB until age 21, when the 10-year rule begins.
You are disabled or chronically ill — you are an EDB and may stretch, under separate definitions.

If you land in the second bullet, keep reading. If you land elsewhere, the stretch math here may not apply to you, and you should confirm your category with the IRA custodian.

The Five Eligible Designated Beneficiaries, Compared

The “10 years younger” rule is easier to understand next to the other four EDB groups. Each keeps the lifetime stretch, but the trigger and the timing differ.

Eligible Designated Beneficiary	How the Stretch Works
Surviving spouse	May treat the IRA as their own or stretch over life expectancy; the most flexible option, per the IRS beneficiary rules
Minor child of the owner	Stretches until age 21, then the 10-year rule starts
Disabled individual	Stretches over life expectancy under the IRS disability definition
Chronically ill individual	Stretches over life expectancy under the IRS chronic-illness definition
Not more than 10 years younger	Stretches over the beneficiary’s own single life expectancy for life

Notice the pattern: four of the five categories depend on a relationship or a health status. Only the “10 years younger” category turns purely on age, which is why siblings and partners rely on it most.

EDB Stretch vs. the 10-Year Rule

The whole value of qualifying is avoiding the 10-year rule. Here is the side-by-side, since misjudging which one applies is the costliest error in this area.

10-Year Rule (most heirs)	Life-Expectancy Stretch (EDBs)
Account must be empty by December 31 of the 10th year after death	Account spreads over the beneficiary’s full life expectancy
Annual RMDs also required in years 1–9 if the owner had already started RMDs, per the final 2024 regulations	Annual RMDs based on the single life table, recalculated by subtracting 1.0 each year
Larger taxable withdrawals compressed into a decade	Smaller taxable withdrawals across decades
Applies to most non-spouse heirs more than 10 years younger	Applies to the five protected groups, including “not more than 10 years younger”

One nuance worth its own sentence: even some 10-year-rule heirs now owe annual RMDs in years one through nine. The final regulations confirmed this controversial reading, and the IRS began enforcing it for 2025. EDBs who stretch avoid that whole problem.

A Fully Worked Stretch Example (Copy This Math)

Numbers make this real. Wherever money is involved, the law gives you a formula, and you can run it yourself.

Suppose Maria inherits a traditional IRA from her older brother Tomás, who dies in 2025. Tomás was 70; Maria is 62, so she is 8 years younger — inside the 10-year limit and an EDB. The IRA holds $300,000 at the end of 2025.

Here is Maria’s first stretch RMD, due by December 31, 2026:

Maria’s age at the end of 2026 is 63.
Her single life expectancy factor at 63, from the IRS table, is roughly 25.4 years, consistent with the Single Life Expectancy Table example.
$300,000 ÷ 25.4 = $11,811 that Maria must withdraw for 2026.

Now the “subtract one” method for later years. As Bogleheads describes the single-life method, you reduce the factor by 1.0 each year rather than looking it up again.

For 2027, her factor is 24.4 (25.4 minus 1.0).
If the balance is then $295,000, her 2027 RMD is $295,000 ÷ 24.4 = $12,090.
For 2028 the factor is 23.4, and so on, until the factor approaches zero.

Maria can always take more than the minimum, but never less. The math is the same for a $200,000 balance and a 38.8 factor giving $5,156 — divide the prior year-end balance by the current factor.

Three Common Scenarios

Real situations rarely look like the textbook. These are the three that come up most.

Scenario 1: The slightly younger sibling.

Who Inherits	What Happens
Brother is 9 years younger than the deceased sister	He is an EDB; he stretches RMDs over his single life expectancy for life, avoiding the 10-year rule

Scenario 2: The beneficiary who is older than the owner.

Who Inherits	What Happens
An aunt, 5 years older than her late nephew	She passes automatically; older heirs are always within the “not more than 10 years younger” test and may stretch

Scenario 3: The heir who just misses the cutoff.

Who Inherits	What Happens
A friend 11 years younger than the owner	She fails the test by one year, becomes a plain designated beneficiary, and must empty the account under the 10-year rule

The third scenario shows the cliff. One extra year of age gap flips a lifetime stretch into a 10-year deadline.

Three Named Examples in Action

David and his late partner. David, 58, inherits a $400,000 IRA from his domestic partner Greg, 60, who died in 2025. They never married, so David is not a “spouse” beneficiary. But David is only 2 years younger, so he qualifies under the “not more than 10 years younger” rule. He stretches RMDs over his life expectancy starting in 2026, keeping most of the account growing tax-deferred.

Priya and her older sister’s IRA. Priya, 67, inherits from her sister Anita, 65, who died in 2025. Priya is 2 years older than Anita, so she clears the test easily. She begins life-expectancy RMDs in 2026 and avoids any 10-year deadline.

Ken, who guessed wrong. Ken, 52, inherits from his uncle, 65 — a 13-year gap. Ken assumes he can stretch like his cousin did years ago. He is wrong; he is more than 10 years younger and not in any EDB group, so the 10-year rule applies. By skipping required annual withdrawals, Ken exposes himself to the 25% missed-RMD penalty.

Deadlines, Penalties, and How to Fix a Missed Withdrawal

Timing is everything. An EDB’s first stretch RMD is generally due by December 31 of the year after the owner’s death, and one is due every December 31 after that.

Miss it, and the cost is steep. As Wolters Kluwer explains the missed-RMD tax, the excise tax is 25% of the amount you failed to withdraw for 2023 and later years. The good news: if you correct the shortfall within the two-year correction window, the penalty drops to 10%.

To fix a missed RMD, follow the steps the IRS expects:

Withdraw the missed amount from the inherited IRA as soon as you notice, per guidance on correcting a missed RMD.
File IRS Form 5329 for each year you missed, reporting the shortfall.
Attach a written explanation of the reasonable cause and the steps you took to fix it.
Request a waiver of the excise tax; the IRS may waive it entirely for reasonable cause if you promptly correct the shortfall.

For help filling out the form, see a dedicated “How to Fill Out Form 5329” guide. The DIY cost is just your time; if your situation is complex — multiple missed years, a trust beneficiary, or a contested estate — a CPA or tax attorney typically charges a few hundred to a few thousand dollars and is worth it.

Traditional vs. Roth: The Tax Difference

The stretch mechanics are nearly identical for a traditional and a Roth inherited IRA, but the tax bite is not. With a traditional IRA, every withdrawal is ordinary taxable income, so spreading it over decades can keep you in a lower bracket. With a Roth, qualified withdrawals are tax-free, so the stretch is about maximizing tax-free growth, not managing brackets.

An EDB with an inherited Roth still takes annual life-expectancy RMDs — Roth owners have no lifetime RMDs, but Roth beneficiaries do. The single life expectancy method applies the same way. The practical takeaway: a Roth stretch is the most valuable of all, because the longer you keep it, the more tax-free compounding you bank.

Does Your State Tax These Distributions?

Start with the federal rule: inherited traditional IRA withdrawals are federally taxable as ordinary income, and qualified Roth withdrawals are not. States layer on top of that, and conformity varies.

Most states with an income tax follow the federal treatment of IRA distributions, taxing traditional withdrawals and exempting qualified Roth ones. A handful of states — including Florida, Texas, Nevada, Wyoming, South Dakota, Washington, Alaska, Tennessee, and New Hampshire — levy no broad income tax, so there is no state tax on these withdrawals at all. Several other states offer retirement-income exclusions that can shelter part of an inherited traditional IRA withdrawal.

The honest answer for a no-income-tax state is complete: that state does not tax the distribution. Everywhere else, confirm your state’s rule with its Department of Revenue before you file, because states do not always mirror federal definitions of “qualified” Roth distributions or retirement-income exclusions.

Mistakes to Avoid

Counting calendar years instead of birth dates. This can wrongly flip your status; the age test uses actual ages, and a miscount risks penalties.
Assuming the old lifetime stretch still applies to everyone. It does not; only EDBs keep it after the SECURE Act, and the rest face the 10-year rule.
Skipping the first-year RMD. An EDB’s first distribution is due the year after death; missing it triggers the 25% excise tax.
Confusing “10 years younger” with the 10-year rule. They are opposites — one grants a stretch, the other imposes a deadline.
Forgetting that Roth beneficiaries owe RMDs. Roth owners do not, but Roth heirs must take annual distributions, and skipping them is penalized.
Failing to file Form 5329 after a missed RMD. Without it, you cannot request the waiver or reduced 10% penalty.
Cashing out the whole account by accident. A lump sum destroys the stretch and can spike you into the top tax bracket in one year.
Ignoring state tax. Assuming your state matches federal rules can leave you with a surprise bill at filing time.

Do’s and Don’ts

Do confirm your exact age gap in years and months — because the EDB test turns on real birth dates, not calendar years.
Do take your first RMD by December 31 of the year after death — because missing it risks a 25% excise tax.
Do keep the IRA titled as an inherited IRA — because retitling it as your own (unless you are a spouse) collapses the stretch.
Do recalculate your factor each year by subtracting 1.0 — because the single-life method is fixed-term, not a fresh table lookup.
Do save documentation of your birth dates — because the IRS can ask you to prove EDB status.
Don’t take less than the minimum — because the shortfall is taxed at 25% (or 10% if corrected in time).
Don’t assume marriage status matters here — because this category is purely about age, not relationship.
Don’t ignore Roth RMDs — because Roth beneficiaries, unlike Roth owners, must take them.
Don’t guess your state’s rule — because conformity to federal treatment is not automatic.
Don’t delay fixing a missed RMD — because the two-year correction window cuts the penalty from 25% to 10%.

Pros and Cons of the Stretch for This Beneficiary

Pro: decades of tax-deferred growth — because the account keeps compounding instead of emptying in 10 years.
Pro: smaller annual taxable income — because spreading traditional withdrawals can hold you in a lower bracket.
Pro: maximum value from inherited Roths — because more years means more tax-free compounding.
Pro: flexibility to take more than the minimum — because you control timing above the floor.
Pro: no looming 10-year deadline — because the account does not have to be emptied on a fixed date.
Con: mandatory annual RMDs — because you cannot let the whole balance ride untouched.
Con: penalty risk every single year — because each missed RMD is its own 25% exposure.
Con: ongoing recordkeeping — because you must track factors and balances for decades.
Con: status can be misjudged — because the birth-date test is easy to miscalculate.
Con: state tax uncertainty — because not every state follows federal treatment.

What to Do Next

Confirm your exact age gap from the owner using both birth dates, and verify you are not more than 10 years younger.
Ask the IRA custodian to title the account as an inherited IRA in your name, keeping the decedent’s name on it.
Find your single life expectancy factor on the current IRS Single Life Expectancy Table for the year after death.
Calculate and take your first RMD before December 31 of that year, then mark the deadline for every future year.
If you already missed an RMD, withdraw it now, file Form 5329, and request a waiver.
Check your state Department of Revenue for how it taxes the distribution.
Call a CPA or tax attorney if a trust is the beneficiary, the estate is contested, or you have multiple missed years. This article is educational and is not a substitute for advice from a licensed professional for your specific situation.

FAQs

Can a beneficiary not more than 10 years younger stretch an IRA?

Yes. For 2025 and 2026, this beneficiary is an Eligible Designated Beneficiary and may take RMDs over their own single life expectancy, avoiding the 10-year rule that applies to most other non-spouse heirs.

Does a beneficiary older than the owner qualify?

Yes. Anyone the same age as or older than the deceased owner automatically passes the “not more than 10 years younger” test and may stretch distributions over their life expectancy.

How is the 10-year age gap measured?

By actual birth dates. You use the real ages of the owner and beneficiary in years and months, not just the calendar years of birth, so the exact gap controls.

When is the first RMD due for this beneficiary?

December 31 of the year after death. An Eligible Designated Beneficiary generally must take the first life-expectancy distribution by the end of the year following the owner’s death.

What is the penalty for missing an inherited IRA RMD?

25%. For 2023 and later years, the excise tax is 25% of the missed amount, reduced to 10% if you correct the shortfall within the two-year correction window.

Which form fixes a missed RMD?

Form 5329. You file IRS Form 5329 for each missed year, attach a reasonable-cause explanation, and request a waiver of the excise tax.

Does this rule apply to inherited Roth IRAs?

Yes. A Roth Eligible Designated Beneficiary still takes annual life-expectancy RMDs, but qualified withdrawals are tax-free, making the Roth stretch especially valuable.

Is a domestic partner covered by this rule?

Yes, if within 10 years. An unmarried partner is not a spouse beneficiary, but qualifies as an EDB if they are not more than 10 years younger than the deceased owner.

What happens if I am exactly 11 years younger?

You do not qualify. A gap of more than 10 years removes EDB status, and you must empty the inherited account under the 10-year rule instead.

Do all states tax inherited IRA withdrawals?

No. States with no broad income tax — such as Florida, Texas, and Nevada — do not tax these withdrawals, while most income-tax states follow the federal treatment of traditional and Roth distributions.

Can I take more than the minimum each year?

Yes. The RMD is a floor, not a ceiling; an Eligible Designated Beneficiary may withdraw more in any year but never less than the calculated minimum.

Did the 2024 final regulations change this stretch?

Largely no. The July 2024 final regulations preserved the life-expectancy stretch for Eligible Designated Beneficiaries while confirming stricter annual-RMD enforcement for many 10-year-rule heirs starting in 2025.
