When it comes to managing retirement income, taxes can be one of your most significant and overlooked expenses. Many retirees wonder whether converting their savings to a Roth IRA can help satisfy their required minimum distributions (RMDs) and reduce their tax burden. It is a smart question, but it is also a common point of confusion. While both involve moving money out of your retirement accounts, the IRS treats Roth conversions and RMDs very differently.
A financial advisor can help you evaluate Roth conversion strategies and understand how they may affect your retirement income and taxes. Connect with an advisor for free.
How RMDs Work
Required minimum distributions (RMDs) are mandatory withdrawals that the IRS requires from certain tax-deferred retirement accounts. Once you reach age 73, you must begin taking these distributions annually from accounts like traditional IRAs and 401(k)s.
The IRS determines the amount you must withdraw each year based on your account balance and life expectancy. Failure to take an RMD can lead to steep penalties, currently 25% of the amount you should have withdrawn.
RMDs ensure that the government eventually collects taxes on the money you set aside in pre-tax retirement accounts. Because these accounts grow tax-deferred, the IRS does not collect income tax until you withdraw funds. RMDs prevent retirees from keeping money in these accounts indefinitely and avoiding taxation altogether.
You must generally take RMDs by December 31 each year. However, you can delay your first required distribution until April 1 of the following year. Keep in mind that delaying your first withdrawal means you will take two RMDs in one calendar year. This could potentially push you into a higher tax bracket.
Each account type also has its own rules. For example, you must calculate RMDs separately for IRAs, but you can take the total amount from one IRA if you prefer. Meanwhile, 401(k)s require distributions from each account individually.
The money you withdraw through RMDs is ordinary income in the year you take it. This, in turn, can increase your taxable income. This can possibly impact your Social Security taxes or Medicare premiums. Instead, some retirees choose to take partial distributions throughout the year to manage cash flow and tax impact. Others time withdrawals based on market conditions.
Planning when and how to take your RMDs strategically can help minimize these tax consequences.
Why a Roth Conversion Does Not Qualify as an RMD
A Roth conversion involves transferring funds from a traditional IRA or another tax-deferred account into a Roth IRA. When you do this, you pay income tax on the converted amount in the year of the transfer. The money then grows tax-free with the option for withdrawals during retirement.
Required minimum distributions work differently. The IRS requires these mandatory withdrawals certain accounts to ensure you pay taxes on pre-tax savings. Once you are subject to RMDs, the IRS requires that you take your full RMD before doing any Roth conversion.
You cannot convert the RMD amount itself; you must withdraw and pay tax on it first. Only funds remaining in the account after the RMD are satisfied and can be converted.
While RMDs increase taxable income without much flexibility, Roth conversions give you more control. They allow you to decide when to pay taxes, potentially reducing future RMD obligations.
By converting funds before RMDs begin or during lower-income years, retirees can build a source of tax-free income that is not subject to future withdrawal requirements.
Can an RMD Be Converted to a Roth IRA?

Once a distribution becomes a required minimum distribution, you may not convert it to a Roth IRA. The IRS explicitly prohibits using RMD funds for Roth conversions.
This means that once you withdraw your RMD from a traditional IRA or other qualified account, that money becomes taxable income. You cannot re-deposit it into a Roth IRA as part of a conversion.
If you want to convert funds to a Roth IRA in a year when you must also take an RMD, you need to take the RMD first. Only the remaining balance in the account after that withdrawal is eligible for conversion. For example, say your RMD for the year is $15,000 and you want to convert $30,000 to a Roth IRA. You must first take the $15,000 RMD and pay taxes on it.
While RMDs themselves cannot be converted, strategic planning can still reduce their long-term tax impact. For example, you may convert portions of your traditional IRA to a Roth IRA before RMDs begin. You typically do this between retirement and age 73 to shrink your future account balance while lowering the size of future RMDs.
This approach spreads taxes over several years. It can potentially keep you in a lower tax bracket while providing greater flexibility later in retirement.

About This Calculator
Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions.
How Income Taxes Are Calculated
-
First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
-
Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer.
-
Based on your filing status, your taxable income is then applied to the tax brackets to calculate your federal income taxes owed for the year.
-
Your location will determine whether you owe local and / or state taxes.
When Do We Update? - We check for any updates to the latest tax rates and regulations annually.
Customer Service - If you would like to leave any feedback, feel free to email info@smartasset.com.
Assumptions
Deductions
- "Other Pre-Tax Deductions" are not used to calculate state taxable income.
Credits
- The only federal credit automatically calculated is the Savers Credit, depending on your eligibility.
- We do not apply any refundable credits, like the Child Tax Credit or Earned Income Tax Credit (EITC).
- We do not apply state credits in our calculations.
Itemized Deductions
- If itemizing at the federal level, you may need to itemize at the state level too. Some states don't allow itemized deductions, which is accounted for in our calculations.
- When calculating the SALT deduction for itemized deductions, we use state and local taxes, and we assume your MAGI.
- We assume that there is no cap to itemized deductions, if a state allows them.
- We do not categorize itemized deductions (such as medical expenses or mortgage interest), which could be subject to specific caps per state.
Local Tax
- Depending on the state, we calculate local taxes at the city level or county level. We do not include local taxes on school districts, metro areas or combine county and city taxes.
- With the exception of NYC, Yonkers, and Portland/Multnomah County, we assume local taxes are a flat tax on either state taxable income or gross income.

Other Options for Reinvesting an RMD You Don’t Need
If you do not rely on your RMD for living expenses, there are several smart ways to repurpose that money.
While you cannot return it to a tax-deferred account, you can still use the funds to grow wealth, reduce future taxes or support long-term financial goals. The key is to move the money intentionally so it continues working for you.
Pay Down Debt or Build Cash Reserves
Using RMD funds to pay off high-interest debt or boost your emergency savings can provide peace of mind and financial flexibility. Reducing liabilities or maintaining a healthy cash cushion can strengthen your long-term financial stability. This is especially the case in retirement.
Invest in a Taxable Brokerage Account
You can use your RMD to make different types of investments. These could include stocks, bonds, mutual funds or ETFs, all through a regular investment account. Though you will still pay taxes on dividends and capital gains, this approach allows for compounding rather than keeping idle cash. Over time, this can help offset the taxes you pay on your RMD.
Contribute to a Spouse’s IRA
If your spouse is under the contribution limit and has earned income, you can use your RMD to fund their IRA. This can be either a traditional or Roth IRA, depending on your eligibility. This strategy will help you keep more money growing in a tax-advantaged account while strengthening your household’s overall retirement plan.
Make a Qualified Charitable Distribution (QCD)
If you are age 70 ½ or older, you can direct up to $111,000 in 2026 from your IRA to a qualified charity. This move counts toward your RMD but is not included in your taxable income. It offers a powerful way to support causes you care about while reducing your tax bill.
An RMD does not have to be a burden but instead, an opportunity to strengthen your financial position. Whether you invest the money, give it away strategically or shore up your reserves, reinvesting your RMD thoughtfully can help you maintain control of your retirement income while aligning with your long-term retirement goals.
Bottom Line

A Roth conversion and a required minimum distribution may both involve moving money out of your retirement accounts. However, they serve very different purposes under IRS rules. An RMD is a mandatory, taxable withdrawal once you reach a certain age, while a Roth conversion is a voluntary move that allows you to create future tax-free income. You cannot use an RMD to fund a Roth conversion, but you can plan ahead to reduce the tax impact of future RMDs through careful timing and proactive conversions.
