A Roth conversion does not count toward your required minimum distribution

When you convert money from a traditional IRA to a Roth IRA, that conversion amount does not satisfy your required minimum distribution (RMD) for the year. The IRS treats these as two separate transactions: your RMD is what you must withdraw, and your Roth conversion is what you choose to move between account types. You still owe the full RMD even if you convert a large amount to Roth.

This distinction matters because it affects how much total money you must take out of your traditional IRA in a given year. If you need $10,000 as your RMD and you convert $15,000 to Roth, you have withdrawn $25,000 total — the $10,000 RMD plus the $15,000 conversion. The conversion does not reduce what you owe as an RMD.

However, you can use the same withdrawal to satisfy both requirements if you structure it correctly. The IRS allows you to take your RMD first and then convert the remainder in the same year, or you can take a single withdrawal and designate part of it as your RMD and part as a conversion. The key is that the RMD portion must still be withdrawn and cannot be rolled back into any IRA.

Key Takeaways

  • Your RMD and your Roth conversion are calculated separately, and converting money to Roth does not reduce the amount you must withdraw as an RMD.
  • You can take a single withdrawal from your traditional IRA and designate part of it as your RMD and part as a Roth conversion, but the RMD portion cannot go back into an IRA.
  • If you convert funds to Roth without first satisfying your RMD, you will owe taxes on the RMD amount and may face a 25% penalty if you do not take it by December 31.
  • The conversion itself is taxable income in the year you perform it, separate from the tax treatment of your RMD.
  • RMDs begin at age 73 for most people under current rules, and the conversion strategy does not change when RMDs start or how much you must take.

How the IRS separates RMD and conversion calculations

The Internal Revenue Service has specific rules about what counts toward an RMD. An RMD is the minimum dollar amount you must withdraw from a traditional IRA, SEP-IRA, or straightforward IRA each year once you reach age 73 (under the find 2.0 Act). The amount is calculated using your account balance on December 31 of the prior year and a life expectancy factor published by the IRS each year.

A Roth conversion is a separate action: you are moving pre-tax or after-tax money from a traditional IRA into a Roth IRA. The IRS does not count this movement as part of your RMD because it is not a distribution from the traditional IRA — it is a transfer between account types. The money stays within the retirement system; it straightforward changes which account holds it and what tax treatment applies going forward.

This separation exists because the RMD rule is designed to may support you withdraw and pay tax on retirement savings during your lifetime. A Roth conversion, by contrast, is a voluntary action that lets you move money into a tax-free account. The IRS wants to make sure you are not using conversions to avoid taking your required distributions.

What happens if you convert but skip your RMD

If you perform a Roth conversion in a year when you also owe an RMD but you do not take the RMD, you will face penalties. The IRS imposes a 25% penalty on the RMD amount you failed to withdraw (reduced to 10% if you correct the shortfall within two years). This penalty applies even if you converted a large sum to Roth in the same year.

You will also owe income tax on the RMD amount as if you had withdrawn it, because the IRS still considers it taxable income for the year. So you pay tax on money you never actually received, plus the penalty. This is one of the costliest mistakes in retirement account management.

To avoid this trap, take your RMD first by December 31, then perform any Roth conversions you want with the remaining balance. Or, if you take a single withdrawal, clearly communicate to your IRA custodian which portion is your RMD and which portion is a conversion. Your custodian will report these separately on your tax forms.

Using a single withdrawal to cover both RMD and conversion

You do not have to take two separate withdrawals. Many people take one withdrawal from their traditional IRA and designate part of it as their RMD and part as a Roth conversion. This works as long as you tell your IRA custodian how to split the money before or at the time of withdrawal.

For example, if your RMD is $12,000 and you want to convert an additional $8,000 to Roth, you can instruct your custodian to withdraw $20,000 total, with $12,000 treated as your RMD and $8,000 treated as a conversion. The $12,000 RMD portion is taxable income and cannot be rolled back into any IRA. The $8,000 conversion portion is also taxable income (unless it comes from after-tax contributions), but it goes into your Roth IRA.

If you do not specify how the withdrawal should be split, your custodian will typically treat the entire amount as a distribution first, which means you satisfy your RMD but do not perform a conversion. You would then need to do a separate conversion with other funds if you want to move money to Roth.

Tax consequences of converting while taking an RMD

Both your RMD and your Roth conversion are taxable events in the year they occur, but they are taxed differently. Your RMD is ordinary income tax — you pay your regular income tax rate on the full amount withdrawn. A Roth conversion is also taxed as ordinary income in the year of conversion, but the money then grows tax-free in the Roth IRA and you owe no tax on withdrawals later.

This means your total taxable income for the year includes both the RMD and the conversion amount. If you convert a large sum in the same year you take an RMD, your income could push you into a higher tax bracket, which affects not only your federal tax rate but also Medicare premiums (through the Income-Related Monthly Adjustment Amount, or IRMAA) and the taxation of Social Security benefits.

Some people space out conversions over multiple years to manage their tax bracket. Others convert in years when their income is lower, such as the year they retire before Social Security starts. The RMD, however, is not optional — you must take it every year once you reach age 73, regardless of your tax situation.

RMD rules for inherited IRAs and Roth conversions

If you inherited a traditional IRA from someone other than a spouse, the RMD rules are stricter. Under the find Act, most non-spouse beneficiaries must empty the inherited IRA within 10 years. During those 10 years, you may owe annual RMDs depending on who the original account owner was and when they died.

If you convert funds from an inherited traditional IRA to an inherited Roth IRA, the same rule applies: the conversion does not count toward your RMD. You must still take the required distribution and then convert separately if you wish. Inherited Roth IRAs have their own RMD rules, so converting does not eliminate future withdrawal obligations — it only changes the tax treatment of future withdrawals.

Spouse beneficiaries have more flexibility. If you inherited your spouse's IRA, you can treat it as your own, which means you do not owe an RMD until you reach age 73. You can also convert it to your own Roth IRA without triggering an when ready RMD, though once you reach 73, the RMD rules explore to any remaining traditional IRA balance.

Frequently Asked Questions

Can I convert my RMD amount to Roth instead of taking it as a distribution?

No. Your RMD must be withdrawn from the traditional IRA and cannot be rolled into a Roth IRA. However, you can withdraw your RMD and then convert other funds from the same IRA to Roth in the same year. The RMD portion is not may be able to access for conversion because it must leave the traditional IRA as a taxable distribution.

What if I convert money to Roth and then realize I forgot to take my RMD?

You can still take your RMD after the conversion, but you will owe the 25% penalty on the RMD amount for the year it was missed (or 10% if corrected within two years). Contact your IRA custodian when ready and take the RMD as soon as possible. The penalty applies based on when the RMD was due, not when you eventually take it.

Does a Roth conversion affect how much my RMD will be next year?

No. Your RMD is based on your account balance on December 31 of the prior year. A Roth conversion reduces your traditional IRA balance, which will lower your RMD calculation for the following year. But the conversion itself does not change your current year's RMD — only the balance at year-end affects next year's calculation.

If I convert my entire traditional IRA to Roth, do I still owe an RMD?

If you convert your entire traditional IRA balance to Roth before your RMD important date, you must still take your RMD for that year. The RMD is calculated based on your December 31 balance of the prior year, so you owe it even if the account is empty by the time the important date arrives. You would need to convert back to traditional IRA or take the RMD from another traditional IRA you own.

Can I use my RMD to fund a Roth conversion?

You can use the funds from your RMD withdrawal to convert to Roth, but only if you do it within 60 days. You withdraw your RMD, then roll it into a Roth IRA within the 60-day window. The RMD portion is still taxable income for the year, and you can only do this once per year across all your IRAs. This strategy is less common because the tax bill is the same as a direct conversion.
