Can You Convert an Inherited IRA to a Roth IRA?

One of the most common questions beneficiaries ask after inheriting a traditional IRA is whether they can convert it to Roth to get tax-free growth going forward. The answer depends entirely on your relationship to the original owner — and for most beneficiaries, the answer is no. Here's what you can and can't do, and the strategies that are actually available to you.

Why non-spouse beneficiaries cannot convert

Roth conversions are governed by IRC § 408A(d)(3), which limits qualified rollover contributions to Roth IRAs to the account's original owner and surviving spouses who elect to treat the inherited IRA as their own. Non-spouse beneficiaries hold a legally distinct "inherited IRA" — they cannot roll it into their own IRA, and therefore cannot convert it.¹

This is not a planning workaround that can be solved by any particular custodian or account structure. The IRS does not permit non-spouse inherited IRA conversions. Any financial institution that completes such a transaction is making an error that would need to be unwound.

The 10-year rule: what non-spouse beneficiaries must do instead

Under the SECURE Act of 2019, most non-spouse beneficiaries who inherit an IRA from someone who died on or after January 1, 2020 must empty the inherited account within 10 years of the original owner's death.² Every dollar that comes out is taxed as ordinary income in the year of distribution — at your marginal rate, on top of your other income.

The 10-year rule replaced the old "stretch IRA," which let beneficiaries take distributions over their own life expectancy — potentially 40+ years for a younger heir. That option is gone for most beneficiaries.

The T.D. 10001 wrinkle: annual RMDs may be required

Whether you can wait until year 10 to empty the account — or must take annual distributions in years 1 through 9 — depends on when the original owner died relative to their Required Beginning Date (RBD).³

The Required Beginning Date is April 1 of the year after the owner turns 73 (born 1951–1959) or 75 (born 1960 or later) under SECURE 2.0.² If your parent died at 74, they were past their RBD — you owe annual RMDs every year during the 10-year window, calculated from the IRS Single Life Expectancy Table using your own age. Missing one triggers a 25% excise tax under IRC § 4974.

Tax strategies for non-spouse beneficiaries

You can't convert, but you can still manage the tax cost significantly with thoughtful distribution timing.

1. Front-load in low-income years

If your income varies — sabbatical, parental leave, early retirement, career transition, a year with large deductions — take larger distributions from the inherited IRA in those years. Every dollar you take in a 22% year instead of a 35% year is a 13-point savings on the same income.

2. Delay distributions if income will drop soon

If you're currently at peak earnings but plan to retire in 3–5 years, take only the minimum required distribution now and accelerate in the years after retirement when your bracket is lower. For beneficiaries without annual RMD requirements (decedent died before RBD), you can take nothing for years 1–9 and take everything in year 10 if that's your lowest-income year.

3. QCDs for beneficiaries age 70½ or older

If you are at least 70½, you can make qualified charitable distributions (QCDs) directly from the inherited IRA to a qualified charity — up to $111,000 per year in 2026.⁴ A QCD satisfies the annual RMD requirement dollar-for-dollar and produces zero taxable income. This is a powerful tool for older beneficiaries with charitable intent who are already in high brackets and don't need the cash.

4. Coordinate with your own Roth conversion plan

If you are simultaneously doing Roth conversions from your own traditional IRA, inherited IRA distributions and your conversions both count as ordinary income in the same year. Watch for bracket spillover, IRMAA thresholds ($218,000 MFJ / $109,000 single in 2026),⁵ and the Social Security torpedo. A year with a large inherited IRA distribution may be a year to convert less from your own IRA.

Surviving spouse: yes, you can convert

A surviving spouse has an option unavailable to any other beneficiary: treating the inherited IRA as their own. Once you elect this treatment and complete the rollover into your own traditional IRA, it is legally your IRA — and can be converted to Roth exactly as you would any IRA you opened yourself.

Spousal rollover + conversion: how it works

1. Elect to treat as your own. Notify the custodian of your intent. The account retransfers into an IRA in your name, either at the same institution or via a direct rollover to a new custodian.
2. Apply your own RMD rules. Your Required Beginning Date is now based on your age (73 or 75 per SECURE 2.0), not your spouse's. If you're 62 and your spouse was 68, you just restarted the RMD clock by 11+ years.
3. Convert during your golden window. If you're under RMD age, you're in the conversion window. Treat it the same as any traditional IRA: calculate your annual conversion capacity based on bracket room, IRMAA ceilings, and Social Security timing.

When to keep it as an inherited IRA instead

The spousal rollover is not always the right move. If you are under 59½ and need distributions from the account, keeping it as an inherited IRA preserves the ability to take distributions penalty-free — something you would lose by rolling into your own IRA (which would then subject you to the 10% early-withdrawal penalty on pre-59½ distributions). Once you roll it to your own IRA and you're under 59½, the money is locked in until 59½ or a 72(t) SEPP arrangement.

Eligible Designated Beneficiaries: different distribution rules, same conversion prohibition

Some beneficiaries — called Eligible Designated Beneficiaries (EDBs) — are exempt from the 10-year rule and can instead use their own life expectancy for distributions:²

• Surviving spouses (and only they may also do the spousal rollover and convert)
• Minor children of the original owner — until the age of majority, then a 10-year rule applies
• Disabled beneficiaries (under IRC § 72(m)(7) definition)
• Chronically ill beneficiaries
• Beneficiaries not more than 10 years younger than the decedent

EDB status gives you more favorable distribution timing — but it does not permit a non-spouse EDB to convert to Roth. The IRC § 408A conversion prohibition applies regardless of EDB status.

The upstream solution: converting before your death

The clearest way to solve the inherited IRA tax problem for your heirs is to solve it before you die — by converting your own traditional IRA to Roth during your golden window. Heirs who inherit a Roth IRA still face the 10-year depletion rule, but there are no annual distribution requirements and every dollar they take out is completely tax-free. Converting at your 22% rate today can save adult children paying 32–37% on every dollar during their own peak-earning years.

When to get an advisor involved

The rules described above — the 10-year rule, the annual RMD requirement when the decedent died post-RBD, the spousal rollover election and its timing, coordination with your own conversion plan — require multi-year tax projection across multiple accounts. The right distribution schedule for a non-spouse beneficiary depends on when your income peaks, when it drops, your own IRA balances, Social Security timing, and IRMAA exposure.

This is exactly the kind of multi-variable problem that a fee-only financial advisor who specializes in Roth conversion strategy and inherited account planning can model across 5–10 years of your specific tax situation.
