Do Roth Conversions Count Toward Your Required Minimum Distribution
Key Takeaways
- Roth conversions are taxable distributions but do not count toward your RMD, so you must withdraw both amounts in the same year.
- The IRS requires you to calculate your RMD based on your December 31 account balance from the prior year, using your age and life expectancy.
- If you convert money and then fail to take your full RMD, you face a 25% penalty on the shortfall (reduced to 10% if corrected within two years).
- The pro-rata rule applies to conversions when you have both pre-tax and after-tax money in traditional IRAs, potentially creating unexpected tax liability.
How the IRS Separates Conversions From RMDs
The IRS views a Roth conversion as a taxable distribution from your traditional IRA. You report it on Form 8606 and pay income tax on the amount converted. However, the tax code does not allow this distribution to count toward your RMD. The two are separate obligations in the same year.
Think of it this way: if your RMD is $10,000 and you convert $15,000 to a Roth, you have taken a $15,000 distribution for tax purposes. But you still owe the $10,000 RMD. You must withdraw at least $10,000 more from your pre-tax accounts, or you face a penalty on the $10,000 shortfall.
This rule applies whether you convert from a traditional IRA, SEP-IRA, or SIMPLE IRA. The conversion itself does not reduce your RMD obligation.
Calculating Your RMD When You Convert
Your RMD is calculated using three pieces of information: your age, your account balance on December 31 of the prior year, and the IRS life expectancy table that matches your age. The IRS publishes these tables in Publication 590-B. You divide your prior-year balance by the life expectancy factor for your age to get the amount you must withdraw.
The key point is that your RMD is based on your December 31 balance from the previous year, not your current balance. If you convert $50,000 in January, that conversion does not reduce the balance used to calculate your RMD. The RMD was already determined on December 31 of the prior year.
For example, if you had $200,000 in your traditional IRA on December 31, 2023, and you are age 73, your 2024 RMD is roughly $7,547 (using the Uniform Lifetime Table). If you convert $50,000 in February 2024, your RMD for 2024 remains $7,547. You must withdraw that amount by December 31, 2024, in addition to the conversion.
The Pro-Rata Rule and Unexpected Tax on Conversions
When you own both pre-tax and after-tax money across all your traditional IRAs, SEP-IRAs, and SIMPLE IRAs, the pro-rata rule applies to any conversion you make. This rule requires you to treat a percentage of your conversion as taxable based on the ratio of pre-tax to after-tax money in all your accounts combined.
This creates a hidden tax cost that many people miss. If you have $100,000 in pre-tax IRAs and $20,000 in after-tax IRAs (perhaps from non-deductible contributions), and you convert $10,000, the IRS treats $8,333 of that conversion as pre-tax money and $1,667 as after-tax money. You pay tax only on the $8,333 portion, but you cannot simply convert the after-tax money tax-free.
The pro-rata rule applies to conversions separately from your RMD. Even if you are taking your RMD at the same time, the pro-rata calculation applies to the conversion amount only. This is why some people with after-tax IRA balances find that converting creates more tax than they expected.
Penalties for Missing Your RMD When You Convert
If you convert money but fail to withdraw your full RMD by December 31, the IRS imposes a penalty on the shortfall. As of 2024, the penalty is 25% of the amount you failed to withdraw (reduced to 10% if you correct the shortfall within two years). This is one of the harshest penalties in the tax code.
The penalty applies to the RMD amount only, not to the conversion. If your RMD is $10,000 and you convert $20,000 but only withdraw $15,000 total, you have a $5,000 RMD shortfall and owe a $1,250 penalty (25% of $5,000).
To avoid this, many people take their RMD first, then convert additional money if they want to. This ensures the RMD is satisfied before any conversion is made. Your IRA custodian can help you designate which withdrawal is your RMD and which is a conversion.
Strategies for Converting While Managing Your RMD
One common approach is to take your RMD as a direct withdrawal to your bank account, then convert additional pre-tax IRA money to a Roth in a separate transaction. This makes it clear to the IRS which withdrawal satisfies the RMD and which is a conversion. Your IRA custodian will report each separately on Form 1099-R.
Another strategy is to convert first, then take your RMD from the remaining balance. This works as long as you withdraw enough to satisfy the RMD by year-end. The order does not matter to the IRS; what matters is that both amounts are withdrawn by December 31.
If you have multiple IRAs, you can aggregate your RMD across all of them but must take the full total from at least one account. You cannot split the RMD among accounts and then convert from a different account and claim the conversion counts toward the RMD. Each account's withdrawal is tracked separately on your 1099-R.
Special Rules for the Year You Turn 72
If you turn 72 in 2024 or later, your first RMD is due by April 1 of the year after you turn 72. This is called your "required beginning date." If you convert money before taking your first RMD, the conversion still does not count toward that RMD.
Many people delay their first RMD until April 1 of the following year, but this creates a problem: you then owe two RMDs in that second year (one for the first year and one for the current year). If you plan to convert, it is often simpler to take your first RMD by December 31 of the year you turn 72, then convert in a separate transaction.
Frequently Asked Questions
Can I convert my RMD amount to a Roth instead of taking it as a withdrawal?
No. Your RMD must be withdrawn from your pre-tax accounts. You can convert additional money beyond your RMD, but the RMD itself cannot be converted. The IRS requires the RMD to be distributed, not moved to another account type.
What if I convert more than my RMD in one year?
The conversion amount and the RMD amount are separate. If you convert $30,000 and your RMD is $10,000, you have taken a $30,000 distribution for tax purposes, but you still owe the $10,000 RMD. You must withdraw at least $10,000 more from your pre-tax accounts by December 31.
Does my Roth IRA have an RMD?
Not during your lifetime. Roth IRAs have no RMD requirement while you are alive. This is one reason conversions are attractive to people who do not need the money. Once you convert to a Roth, that money grows tax-free and is never subject to RMD rules.
If I take my RMD early in the year, can I convert the rest of my IRA later?
Yes. You can take your RMD in January and convert the remaining balance in December. As long as both transactions happen by December 31, you have satisfied both the RMD and the conversion. Your custodian will report each on a separate 1099-R form.
What happens if I miss my RMD but I converted money that year?
The conversion does not reduce your RMD shortfall. If you owe a $10,000 RMD and only withdrew $5,000 (even if you converted $20,000), you have a $5,000 RMD shortfall and face a 25% penalty on that amount. The conversion is a separate transaction and does not satisfy the RMD.
