Yes, you can convert an inherited IRA to a Roth, but the rules depend on your relationship to the person who died

You can convert funds from an inherited IRA to an inherited Roth IRA, but the process and tax consequences differ sharply depending on whether you are a spouse, a non-spouse beneficiary, or a domestic partner. Spouses have the most flexibility — they can treat the inherited IRA as their own or convert it to a Roth. Non-spouse beneficiaries can convert, but they cannot avoid the income tax that comes with it, and they face stricter withdrawal deadlines under current law. The conversion itself is a straightforward transaction with your IRA custodian, but the tax bill arrives in the same year you convert.

The key difference is this: spouses can roll an inherited IRA into their own name first, which delays required withdrawals and gives them more control. Non-spouse beneficiaries cannot do this. They must convert directly to an inherited Roth IRA and pay income tax on the full amount in the year of conversion. Both paths result in a Roth account, but the tax timing and withdrawal rules are different.

Key Takeaways

  • Surviving spouses can roll an inherited IRA into their own IRA and then convert to a Roth, or convert the inherited IRA directly to an inherited Roth IRA.
  • Non-spouse beneficiaries can convert an inherited IRA to an inherited Roth IRA, but must pay income tax on the full amount converted in that tax year.
  • The conversion does not reset the required minimum distribution deadline — non-spouse beneficiaries must still empty the account by the deadline set by the original account owner's age.
  • You report the conversion on your tax return for the year it occurs; the IRA custodian will send you a Form 1099-R showing the distribution and conversion.
  • Domestic partners registered under state law have the same conversion rights as spouses in most states, but should confirm their state's rules with a tax professional.

Spouse beneficiaries have two conversion paths

If you inherited an IRA from your spouse, you have more options than any other beneficiary. You can roll the inherited IRA into an IRA in your own name and then convert that IRA to a Roth IRA. Alternatively, you can convert the inherited IRA directly to an inherited Roth IRA without rolling it first. Both paths result in a Roth IRA, but they affect your required minimum distributions differently.

If you roll the inherited IRA into your own IRA and then convert to a Roth, you treat the account as if you owned it all along. You do not have to take required minimum distributions until you reach age 73 (under current law). If you convert the inherited IRA directly to an inherited Roth IRA without rolling it first, you must still take required minimum distributions based on the original account owner's life expectancy, even though the money is now in a Roth. Most spouses choose to roll the inherited IRA into their own name first, because it delays required distributions and gives them more control over the account. You make this choice by instructing your IRA custodian to transfer the funds directly to an IRA you own. Then, in a separate transaction, you convert that IRA to a Roth.

Non-spouse beneficiaries can convert but face immediate income tax

If you inherited an IRA as a non-spouse beneficiary — as an adult child, sibling, friend, or other person — you can convert the inherited IRA to an inherited Roth IRA. However, you must pay income tax on the entire amount you convert in the year the conversion happens. There is no way around this tax bill, and it can be substantial if the inherited IRA is large.

The conversion itself is simple: you contact your IRA custodian and ask them to convert the inherited IRA to an inherited Roth IRA. The custodian processes the request and sends you a Form 1099-R for that tax year showing the distribution and conversion. You report this on your tax return, and the amount you converted is added to your taxable income for that year. One strategic consideration: you do not have to convert the entire inherited IRA at once. You can convert a portion one year and another portion in a later year, spreading the tax bill across multiple tax years. This is called a partial conversion. For example, if you inherited a $100,000 IRA, you might convert $25,000 in year one, $25,000 in year two, and so on. Each conversion triggers income tax only on the amount converted that year.

The required minimum distribution deadline does not change after conversion

Converting an inherited IRA to a Roth does not reset your withdrawal deadline. If you are a non-spouse beneficiary, you must still empty the inherited Roth IRA by the deadline that was set based on the original account owner's age and life expectancy. Under current law, most non-spouse beneficiaries must empty the account within 10 years of the account owner's death.

This means you cannot convert to a Roth and then let the money sit untouched for decades. The Roth conversion gives you tax-free growth on the money you convert, but only if you follow the withdrawal rules. If you fail to withdraw by the deadline, you owe a 25% penalty on the amount that should have been withdrawn (reduced to 10% if you correct it within two years). Spouse beneficiaries who roll the inherited IRA into their own name do reset the deadline — they can treat the account as their own and follow their own required minimum distribution schedule. This is another reason many spouses choose to roll first rather than convert directly.

How to request the conversion from your IRA custodian

Contact the financial institution that holds the inherited IRA — this might be a bank, brokerage firm, or investment company. Tell them you want to convert the inherited IRA to an inherited Roth IRA. They will ask you to complete a conversion request form, which is usually available on their website or by phone.

The custodian will ask you to specify the amount you want to convert. If you want to convert the entire account, say so. If you want to convert only part of it, provide the dollar amount. The custodian will then process the conversion, which typically takes a few business days to a week. After the conversion is complete, the custodian will send you a Form 1099-R in January of the following year. This form shows the amount distributed from the inherited IRA and the amount converted to the inherited Roth IRA. You will use this form to report the conversion on your tax return. Keep a copy for your records.

The tax bill arrives in the same year as the conversion

When you convert an inherited IRA to a Roth, you owe federal income tax on the amount converted. The tax is calculated at your ordinary income tax rate for that year. If you convert $50,000 and your tax rate is 24%, you owe $12,000 in federal income tax on the conversion. You may also owe state income tax, depending on where you live.

You do not pay this tax to the IRA custodian. Instead, you report the conversion on your tax return when you file for that tax year. If you expect a large tax bill, you can make estimated tax payments to the IRS during the year to avoid penalties. Talk to a tax professional before you convert if the amount is substantial, because they can help you understand the full tax impact and decide whether to convert all at once or spread it across multiple years. One important note: if the inherited IRA contains both pre-tax and after-tax contributions, the tax calculation is more complex. The IRS uses a pro-rata rule that requires you to calculate the tax based on the ratio of pre-tax to after-tax money in all your IRAs combined. This is a situation where a tax professional's help is worth the cost.

Domestic partners and state-registered relationships

If you are in a domestic partnership or civil union registered under your state's law, you may have the same conversion rights as a spouse. However, federal tax law does not automatically recognize all state-registered relationships. Some states treat registered domestic partners as spouses for federal tax purposes, while others do not.

Before you convert, confirm your state's rules with a tax professional or contact the IRS directly. If your state recognizes your relationship as equivalent to marriage for federal tax purposes, you can use the spouse conversion rules. If not, you will follow the non-spouse beneficiary rules, which means you must pay income tax on the full conversion amount. The IRS website has a state-by-state reference, but a tax professional familiar with your state can give you a definitive answer in minutes.

Frequently Asked Questions

Can I convert an inherited IRA to a Roth if the original owner had already started taking required minimum distributions?

Yes. The fact that the original owner was taking required minimum distributions does not prevent you from converting. However, if you are a non-spouse beneficiary, you still must follow the 10-year withdrawal deadline that applies to inherited IRAs. Converting to a Roth does not extend this deadline.

What happens if I convert an inherited IRA to a Roth and then need the money before the required withdrawal deadline?

You can withdraw the money, but you must still meet the 10-year deadline for emptying the account. Withdrawals from an inherited Roth IRA are tax-free if the conversion happened at least five years before the withdrawal. If you withdraw before five years have passed, you may owe taxes on the earnings portion of the withdrawal.

Do I have to convert the entire inherited IRA, or can I convert just part of it?

You can convert as much or as little as you want. Many beneficiaries convert in stages over several years to spread the tax bill. Just remember that non-spouse beneficiaries must still empty the entire account by the 10-year deadline, whether converted or not.

If I convert an inherited IRA to a Roth, do I have to pay the 10% early withdrawal penalty?

No. Conversions of inherited IRAs are not subject to the 10% early withdrawal penalty, regardless of your age. However, you still owe ordinary income tax on the amount converted (for non-spouse beneficiaries) or on the pre-tax portion (for spouses).

Can I undo a Roth conversion of an inherited IRA if I change my mind?

No. The IRS eliminated the ability to undo conversions (called recharacterization) for all conversions made after 2017. Once you convert, the conversion is permanent, and you cannot reverse it to avoid the tax bill.
