Can you convert an inherited IRA to a Roth? The answer splits hard by your relationship to the person who died. A surviving spouse can, but only after rolling the inherited account into their own IRA first. A non-spouse beneficiary cannot convert an inherited traditional IRA at all. This 2026 guide covers each beneficiary type, the tax cost, the inherited 401(k) exception, and why converting your own IRA may be a stronger option for many owners.
A non-spouse beneficiary cannot convert an inherited traditional IRA to a Roth. The IRS treats it as a legally distinct “inherited IRA” that cannot be rolled or converted. A surviving spouse can, but only after a spousal rollover moves the money into their own IRA, followed by a normal Roth conversion. An inherited 401(k) is the exception: a designated beneficiary can roll it directly into an inherited Roth IRA.
Can you convert an inherited IRA to a Roth? The short answer
Whether you can convert an inherited IRA to a Roth depends on one fact: are you the surviving spouse or not. A surviving spouse can, after a spousal rollover into their own IRA. A non-spouse beneficiary cannot convert an inherited traditional IRA, though a taxed distribution can be redeposited into their own Roth within annual limits. An inherited 401(k) follows separate, more flexible rules.

| Beneficiary type | Can convert to a Roth? | How |
|---|---|---|
| Surviving spouse | Yes, indirectly | Spousal rollover into own IRA, then a standard Roth conversion of any amount |
| Non-spouse (adult child, grandchild, other individual) | No | Cannot convert; may take a taxable distribution and contribute to own Roth within limits |
| Beneficiary of an inherited 401(k) or 403(b) | Yes, directly | Direct rollover of the inherited employer plan into an inherited Roth IRA (taxable) |
| Trust or estate | No | Same prohibition as a non-spouse individual beneficiary |
Why can’t a non-spouse beneficiary convert an inherited IRA?
A non-spouse beneficiary cannot convert an inherited traditional IRA because the IRS treats it as a legally separate account, titled in the deceased owner’s name for the benefit of the heir. Only the original owner or a surviving spouse who assumes ownership can convert IRA assets. A non-spouse has no ownership rights that permit a conversion, so the option does not exist in the tax code.
Money leaves an inherited traditional IRA only as a distribution taxed as ordinary income in the year received, and that distribution cannot be rolled back or converted. A non-spouse who wants Roth treatment must contribute the after-tax proceeds to their own Roth within the limits described below.
How can a surviving spouse convert an inherited IRA to a Roth?
A surviving spouse can convert an inherited IRA to a Roth by first completing a spousal rollover, among the more flexible inheritance treatments in the tax code. The spouse moves the inherited balance into an IRA titled in their own name, becoming the owner rather than a beneficiary. Once the assets sit in that IRA, a normal Roth conversion is available for any amount, in any year.
- Complete the spousal rollover into an IRA in the surviving spouse’s own name, so the spouse owns the account outright.
- Convert any amount to a Roth. A conversion is uncapped, taxable as ordinary income, and irreversible, and you cannot convert an RMD.
- Mind the December 31 deadline. Spreading conversions across years often keeps the spouse in lower brackets; see how much to convert to a Roth.
What about an inherited 401(k)? Can that be rolled into a Roth?
Yes. An inherited 401(k) or 403(b) is the one case where a non-spouse can effectively convert inherited retirement money to a Roth. Under the qualified-plan rules, a designated beneficiary can request a direct rollover of the inherited employer plan into an inherited Roth IRA. This exception applies to employer plans only, not to traditional IRAs, and must be a direct trustee-to-trustee rollover.
The rollover is taxable: the pre-tax amount counts as ordinary income in the year of the rollover. The inherited Roth IRA is still subject to the 10-year distribution requirement, but qualified withdrawals come out tax-free. A beneficiary who wants Roth treatment often rolls the plan directly, because once the money lands in an inherited traditional IRA the conversion door closes.
What can a non-spouse beneficiary do instead?
A non-spouse beneficiary who cannot convert an inherited traditional IRA still has a workaround: take a distribution, pay ordinary income tax on it, then contribute the after-tax cash to their own Roth IRA within the annual limits. The catch is that Roth contribution limits are small next to most inherited balances, so this converts only a slice each year.
- Take a measured distribution that fits your bracket rather than draining the account in one year; it is taxed as ordinary income.
- Fund your own Roth IRA. The 2026 limit is $7,500 ($8,600 if age 50 or older), only if income is under the phase-out ($153,000 to $168,000 single, $242,000 to $252,000 married filing jointly).
- Smooth the 10-year window to avoid stacking a large balance into one high-income year and tripping the net investment income tax or Medicare thresholds.
What the 10-Year Rule Actually Requires in 2026
The 10-year rule requires most non-spouse beneficiaries to empty an inherited IRA by December 31 of the tenth year after the owner’s death. Whether annual distributions are required inside that window depends on when the owner died relative to their required beginning date (RBD), which is April 1 after age 73 (age 75 for those born in 1960 or later). Final IRS regulations settled the framework for 2025 and 2026.
- Owner died before their RBD: no annual distributions are required; the heir can wait and take the full balance any time through year 10.
- Owner died on or after their RBD: the heir must take annual RMDs in years 1 through 9, then fully drain the account by the end of year 10.
The penalty waivers the IRS granted from 2021 through 2024 have ended, and annual RMDs inside the window are now enforced for 2025 and 2026. A missed distribution triggers a 25% excise tax, reducible to 10% if corrected promptly. More generous rules apply to eligible designated beneficiaries (surviving spouses, minor children of the owner, disabled or chronically ill individuals, and beneficiaries less than 10 years younger than the owner). See our overview of the 2026 required minimum distribution rules.
The Tax Trap Hiding Inside Inherited Traditional IRAs
Every dollar inside a traditional IRA is untaxed, and every distribution is taxed as ordinary income. Compressing a large inherited balance into 10 years often lands distributions in the 32% or 35% federal bracket during the heir’s peak earning years, plus state tax, a hit the old stretch IRA absorbed and the 10-year rule does not.
Compress a $1.5 million inherited IRA into 10 years and the heir adds roughly $150,000 or more to income each year. That higher Modified Adjusted Gross Income can subject the heir’s other investment income to the 3.8% net investment income tax (over $200,000 single, $250,000 married filing jointly) and, for an heir 63 or older, trigger IRMAA Medicare surcharges two years later once MAGI clears $109,000 single or $218,000 joint.
Why Converting Your Own IRA May Let Heirs Inherit a Roth
Because a non-spouse cannot convert an inherited IRA, much of the planning room sits with the original owner. An IRA owner who converts to a Roth during life can pass a tax-free account to heirs. Final IRS regulations confirmed that a Roth IRA owner is treated as having died before their required beginning date, so heirs of an inherited Roth face no annual RMDs inside the 10-year window and qualified distributions are tax-free.
The inherited Roth is still subject to the 10-year rule, but the heir can let it compound and take the full balance in year 10 with no income tax, no bracket creep, and no IRMAA risk, provided the original Roth was open at least five years. Our page on inherited Roth IRAs and the 10-year rule covers the mechanics.
Weighing Conversion Tax Now Against Beneficiary Tax Later
A Roth conversion is not free: you pay ordinary income tax on the converted amount in the conversion year, it is irreversible, and you cannot convert an RMD. The idea behind the strategy is bracket arbitrage, which compares the rate the owner would pay to convert now against the rate the heir would likely face on inherited distributions later, inside the 10-year window.
When the owner would convert in a bracket lower than the heir’s expected future bracket, the comparison tends to favor converting; when the owner already sits at or above the heir’s likely rate, it does not. The direction of that comparison, rather than any single projected number, is what informs the decision, and it turns on each family’s income, state of residence, account growth, and timing.
The 2026 24% bracket runs to $201,775 for single filers and $403,550 for married couples filing jointly, so many owners have room to convert within the 22% to 24% range before reaching the 32% bracket, which begins at $201,775 single and $403,550 married filing jointly. A tax professional can map how much bracket room a specific household has in a given year.
Five Reasons the 10-Year Rule Strengthens the Conversion Case
The 10-year rule compresses inherited traditional IRA distributions into a decade, often pushing heirs into higher brackets than the original owner faces today. That gap between the owner’s current rate and the heir’s future rate is what makes an owner-level Roth conversion worth weighing. Five features of the rule tend to reinforce that case for many owners.
- Bracket arbitrage is now generational. Retirees in their sixties often sit in lower brackets than their working-age children.
- Rate certainty favors acting now. Converting under today’s published 2026 brackets locks in the cost.
- RMD interaction becomes simpler. Roth IRAs have no lifetime RMDs for the owner, shrinking what passes under the 10-year rule.
- IRMAA risk shifts to a year you control. A conversion is planned; a compressed inherited distribution is reactive.
- The surviving spouse keeps options. Conversions during either spouse’s lifetime shrink the balance children inherit later.
What Could Weaken the Case
Roth conversions are not universally correct, and several situations argue against converting aggressively. Each turns on the owner’s current bracket, who the beneficiary is, and how the conversion tax gets paid. When the owner already sits in a high bracket, when a charity is the heir, or when the tax must come from the IRA itself, the case for converting weakens considerably.
- The owner is already in a high bracket. Converting at 35% when the heir would face 24% is usually a losing trade.
- The beneficiary is a charity. Charities pay no income tax on inherited IRA distributions, so converting first only adds friction.
- Conversion tax must come from the IRA itself. Conversions work best when the tax is paid from non-retirement funds.
- The owner expects to spend most of the IRA. If the account funds living expenses anyway, the inheritance question shrinks.
Coordinating Conversions With Estate Planning
The 10-year rule reshapes beneficiary designations, trust language, and drawdown order, not just the conversion math itself. An IRA passes by beneficiary designation rather than by will, so designations and trust provisions set before the SECURE Act may no longer fit the current rules. Reviewing those documents alongside any conversion plan can help the two work together rather than at cross purposes.
- Conduit trusts drafted before 2020 may force compressed distributions taxed at trust income tax rates, which reach the top bracket at a low income threshold.
- Splitting Roth and traditional assets across heirs can improve the family’s after-tax outcome.
- Drawdown order shifts when the goal is to leave Roth, not traditional, to non-spouse heirs.
Frequently Asked Questions
Can you convert an inherited IRA to a Roth IRA?
It depends on your relationship to the owner. A non-spouse beneficiary cannot convert an inherited traditional IRA to a Roth, because the IRS treats it as a legally distinct account. A surviving spouse can, but only after a spousal rollover into their own IRA followed by a standard conversion. An inherited 401(k) can be rolled directly to an inherited Roth IRA.
Can a non-spouse beneficiary convert an inherited IRA to a Roth?
No. A non-spouse beneficiary cannot convert an inherited traditional IRA to a Roth under IRS rules. The only alternative is to take a distribution, pay ordinary income tax on it, and contribute the after-tax cash to your own Roth IRA, limited to $7,500 in 2026 ($8,600 if age 50 or older) and subject to income phase-outs.
Can a surviving spouse convert an inherited IRA to a Roth?
Yes. A surviving spouse first completes a spousal rollover, moving the inherited IRA into an IRA in their own name and becoming the owner. From there they can convert any amount to a Roth. The converted amount is taxable ordinary income in the conversion year, is uncapped, and is irreversible, with a December 31 deadline each year.
Can you convert an inherited 401(k) to a Roth IRA?
Yes. A designated beneficiary can roll an inherited 401(k) or 403(b) directly into an inherited Roth IRA. This qualified-plan exception applies to employer plans only, not to traditional IRAs, and must be a direct trustee-to-trustee rollover. The pre-tax amount rolled over is taxed as ordinary income in the year of the rollover.
Do you pay taxes when you convert an inherited IRA to a Roth?
Yes. Any conversion or qualified-plan rollover to a Roth is taxed as ordinary income in the year it happens. A surviving spouse’s conversion and an inherited 401(k) rollover both add the converted amount to taxable income. A non-spouse’s alternative, taking a distribution from an inherited traditional IRA, is likewise taxed as ordinary income in the year received.
What is the 10-year rule for inherited IRAs?
The 10-year rule requires most non-spouse beneficiaries to empty an inherited IRA by December 31 of the tenth year after the owner’s death. If the owner died on or after their required beginning date, annual RMDs are also required in years 1 through 9. A missed distribution triggers a 25% excise tax, reducible to 10% if corrected promptly.
