A Roth conversion does not count toward your required minimum distribution

The IRS treats a Roth conversion and a required minimum distribution (RMD) as two separate transactions. When you convert money from a traditional IRA to a Roth IRA, that amount does not reduce the RMD you must take from your traditional IRA that same year. You have to do both: take your full RMD from the traditional account, and then convert additional money if you choose to.

This matters because it means converting to a Roth does not give you a way to avoid taking your RMD. The IRS requires you to withdraw a specific dollar amount each year once you reach age 73 (as of 2023, under current law). That withdrawal is separate from any conversion you make.

However, there is one exception: you can use your RMD itself as the source of the conversion. If you take your required minimum distribution and then immediately convert that same money to a Roth, the conversion counts as a conversion—but the RMD requirement is still satisfied because you withdrew the money. This is a common strategy, but it does not reduce what you owe; it just means you are converting money you were going to withdraw anyway.

Key Takeaways

  • Your RMD and any Roth conversion are calculated and tracked separately by the IRS, so converting money does not lower your RMD amount.
  • You must take your full RMD in the calendar year it is due, even if you also convert money to a Roth that same year.
  • You can use your RMD withdrawal as the source of a Roth conversion, which satisfies both the withdrawal requirement and creates a conversion in one transaction.
  • The IRS reports RMDs and conversions on different tax forms, and both amounts appear on your tax return for the year.

How the IRS calculates your RMD separately from a conversion

The IRS calculates your RMD based on your account balance on December 31 of the prior year and your age. That calculation happens independently of any conversion you make during the current year. The RMD is a mandatory withdrawal; the conversion is optional. Because they are separate events, one does not offset the other.

Your financial institution reports the RMD on Form 1099-R in box 2a (the gross distribution) and box 2b (the taxable amount). A Roth conversion also appears on Form 1099-R, but in a different box and with a different code. When you file your tax return, both amounts are listed, and you pay tax on both (unless part of the RMD came from after-tax contributions).

If you fail to take your RMD, the IRS imposes a penalty equal to 25 percent of the shortfall (reduced to 10 percent if you correct it within two years). A Roth conversion does not reduce this penalty because it does not count toward the RMD requirement.

Converting your RMD itself as a strategy

Many people use their RMD as the source of a Roth conversion because they have to withdraw the money anyway. You take the RMD from your traditional IRA, and then immediately convert it to a Roth. This satisfies your RMD requirement and moves money into a tax-free account in one step.

The tax consequence is the same either way: you owe income tax on the amount you convert. But by converting your RMD, you avoid having the money sit in a taxable account and then having to convert it later. The money goes directly from traditional to Roth.

This strategy works best if you do not need the RMD to live on. If you need the cash, you would take the RMD and spend it, which defeats the purpose of converting. If you do not need it, converting lets you move it into an account where it can grow tax-free and where you will never have to take RMDs from it.

What happens if you convert more than your RMD

You can convert more money than your RMD requires you to withdraw. For example, if your RMD is $10,000 and you convert $25,000, you have satisfied the RMD requirement (by withdrawing at least $10,000) and also converted an additional $15,000. Both amounts are taxable in the year of the conversion.

The IRS does not limit how much you can convert in a single year, so you could convert your entire traditional IRA balance if you wanted to. The only limit is the tax bill you create by doing so. Converting large amounts in one year can push you into a higher tax bracket.

Timing: when your RMD must be taken versus when you convert

Your RMD must be taken by December 31 of the year it is due (with one exception: if it is your first RMD, you can delay it until April 1 of the following year, but you will then owe two RMDs in that second year). A Roth conversion can happen at any time during the year, or even after the RMD deadline, but the conversion itself does not extend your RMD deadline.

If you miss your RMD deadline, you cannot make up for it by converting money later. The RMD is a separate requirement with its own deadline. You must take the RMD by December 31, and you can convert money whenever you choose, but the two deadlines are independent.

Tax reporting: how RMDs and conversions appear on your return

Your financial institution sends you a Form 1099-R for each IRA you own. If you took an RMD and made a conversion in the same year from the same account, you may see both transactions on one form or on separate forms, depending on how the institution reports them.

On your tax return (Form 1040), you report the total of all distributions from traditional IRAs on line 4a, and the taxable portion on line 4b. This includes both RMDs and conversions. If you made a conversion, you also file Form 8606 to report the conversion details and track your basis in the Roth IRA.

The key point: both the RMD and the conversion are taxable events in the year they occur, and both appear on your return. They do not cancel each other out or reduce each other's tax impact.

Frequently Asked Questions

Can I count a Roth conversion toward my RMD if I convert the exact amount I owe?

No. If your RMD is $10,000 and you convert exactly $10,000, you have satisfied the RMD requirement (because you withdrew $10,000), but the conversion itself does not count as the RMD. The IRS sees them as two separate things. You owe tax on the $10,000 as a conversion, and you have also satisfied your $10,000 RMD withdrawal requirement. Both are true at the same time, but they are separate obligations.

What if I convert money and then take my RMD later in the year?

That works fine. You can convert in January and take your RMD in December, or vice versa. The order does not matter. What matters is that by December 31, you have taken your full RMD from your traditional IRA accounts (combined across all accounts you own). Conversions can happen before, after, or at the same time as your RMD.

Do I have to convert money if I am taking an RMD?

No. Taking an RMD is mandatory once you reach age 73. Converting is optional. You can take your RMD and leave the rest of your traditional IRA untouched. You do not have to convert anything. The two are completely separate decisions.

If I convert my entire traditional IRA, do I still have to take an RMD?

Once you convert all the money out of your traditional IRA, there is no balance left, so there is no RMD to take from that account. However, if you own multiple traditional IRAs, you must still take RMDs from the others. And Roth IRAs themselves have no RMD requirement during your lifetime, so converting everything to a Roth eliminates future RMDs—but you still owe tax on the conversion in the year you do it.

Can I use a Roth conversion to reduce a penalty for missing my RMD?

No. If you miss your RMD deadline, the IRS imposes a penalty on the amount you failed to withdraw. A conversion made after the deadline does not reduce or eliminate that penalty. You would need to take the missed RMD and file an amended return to potentially reduce the penalty. The conversion and the RMD are separate obligations with separate deadlines.
