The Required Minimum Distribution (RMD) for an IRA is the minimum amount of money that must be withdrawn from certain retirement accounts each year, starting at a specific age. These IRS rules ensure that taxes—often deferred for decades—are eventually paid on retirement earnings.
Understanding how RMD tax works is essential for anyone approaching retirement age or managing multiple IRA accounts.

What Is RMD Tax?
The RMD tax refers to the federal income tax you owe on your annual required minimum distributions. Since most retirement accounts like traditional IRAs, SEP IRAs, and SIMPLE IRAs are funded with pre-tax dollars, distributions are taxed as ordinary income when withdrawn. According to the IRS, the purpose of RMDs is to ensure individuals do not defer taxes indefinitely [1].
RMDs can push retirees into higher tax brackets and even affect Medicare premiums or Social Security taxation, making planning critical.
What Does RMD Stand For
RMD stands for Required Minimum Distribution, the minimum withdrawal that must be taken each year once you reach the required starting age. This requirement applies to tax-deferred retirement accounts to guarantee that taxes on the invested funds are eventually paid to the IRS.
What Is an RMD for an IRA
An RMD for an IRA is the government-mandated withdrawal you must make from your individual retirement account after reaching a certain age—currently 73 under the SECURE 2.0 Act [2]. The withdrawal amount is calculated using your account balance and life expectancy.
Unlike traditional IRAs, Roth IRAs are exempt from RMDs during the account holder’s lifetime.
Breakdown of RMDs for IRAs
Age to Begin
The RMD age is currently 73 for individuals born between 1951 and 1959. Beginning in 2033, the age increases to 75. If you were required to begin RMDs before 2023, you must continue following your existing schedule [3].
Types of Accounts
RMDs apply to:
- Traditional IRAs
- SEP IRAs
- SIMPLE IRAs
- Employer-sponsored retirement plans such as 401(k) and 403(b) accounts
Roth IRAs remain exempt while the owner is alive, though inherited Roth IRAs have separate rules [4].
Calculation
The IRS Publication 590-B explains that RMDs are calculated by dividing your prior year-end account balance by your life expectancy factor from the IRS Uniform Lifetime Table [5]. For example, a 73-year-old with a $500,000 IRA and a factor of 26.5 would have an RMD of approximately $18,868.
Withdrawal Deadlines
Your first RMD must be taken by April 1 of the year following the year you turn 73. Every subsequent RMD must be withdrawn by December 31. Failing to take RMDs on time may lead to steep penalties [6].
Penalties
Missing or underpaying your RMD triggers a 25% excise tax on the amount not withdrawn (reduced to 10% if corrected quickly) [7]. The IRS allows you to request a waiver using Form 5329 [8] if you had a reasonable cause for the error
Taxation
All RMD withdrawals are taxed as ordinary income, not capital gains [9]. Depending on your total income, this could affect your tax bracket and eligibility for credits or deductions. Proper RMD tax planning helps mitigate these effects, particularly for retirees managing multiple income streams.
IRA vs. Other Plans
Employer plans like 401(k)s require separate RMDs unless you roll them into an IRA [10]. Unlike IRAs, RMDs from employer plans can sometimes be delayed if you’re still employed and not a 5% owner of the company sponsoring the plan [11].
Beneficiaries
For inherited IRAs, most non-spouse beneficiaries must withdraw the entire account balance within 10 years of the original owner’s death. If your sole beneficiary is your spouse and they are more than 10 years younger, the IRS allows a longer payout period using the Joint Life and Last Survivor Table, which generally results in smaller required withdrawals each year [12].
Delaying RMDs
If you’re still working past 73 and participating in your employer’s qualified plan, you may be able to delay RMDs until after retirement. However, this does not apply to IRAs [13].
How Do You Determine RMD for an IRA?
To help you determine your annual withdrawal from a non-inherited traditional IRA, you should use this worksheet [14] unless your spouse is the sole beneficiary of your IRA and is more than 10 years younger than you—in that case, you’ll use a different life expectancy table (the Joint Life and Last Survivor Table).
- Find your IRA balance as of December 31 of the previous year.
- Locate your distribution period using the Table III (Uniform Lifetime Table) based on your age as of your birthday in the current year.
- Divide your account balance by the distribution period.
- The result is your required minimum distribution for the year.
- Repeat these steps for each of your non-inherited traditional IRAs.
- Once you determine the RMD amount for each account, you may withdraw the total required amount from any one or more of your traditional IRAs.
What Is the Biggest RMD Mistake?
The most common RMD mistake is missing the first withdrawal deadline or taking it from the wrong account. Both can trigger unnecessary penalties [15]. Many retirees also overlook that RMDs are required for each IRA they own, though you may take the total amount from one account if you prefer [16]. Working with a qualified tax advisor helps you coordinate RMDs across multiple plans and avoid errors that could increase your tax bill.
How Do RMDs Affect Social Security?
Taking Required Minimum Distributions (RMDs) can increase your adjusted gross income (AGI)—and that may cause more of your Social Security benefits to become taxable. According to IRS Tax Tip 2022-22, the portion of your benefits subject to federal income tax depends on your total income and filing status [17].
Here’s how it works:
- Add half of your annual Social Security benefits to your other income—including RMDs, wages, dividends, pensions, and capital gains.
- If you’re single and the total exceeds $25,000, or married filing jointly with more than $32,000, part of your benefits may be taxable.
- Up to 85% of your benefits can be taxable if your combined income exceeds $34,000 (single) or $44,000 (married filing jointly).
Can I Invest My RMD in a Roth IRA?
You cannot roll your RMD directly into a Roth IRA. Once withdrawn, RMD funds are considered taxable income and are not eligible for rollover.
However, after taking your required distribution, you may still contribute new funds to a Roth IRA if you meet the IRS’s income and contribution limits.
If you want to move pre-tax savings into a Roth, you can do a Roth conversion. The IRS
allows this through:
- A rollover, where you transfer funds from a traditional IRA to a Roth IRA within 60 days, or
- A trustee-to-trustee transfer, where the funds move directly between accounts.
Note: The 60-day rule applies strictly, though exceptions exist if a financial institution error caused the delay [18].
Frequently Asked Questions (FAQs)
How does the IRS know if I took my RMD?
Financial institutions report IRA distributions annually using Form 1099-R, and they also submit Form 5498, which shows your year-end balance [19].
What happens if I take more than my required RMD?
There’s no penalty for withdrawing more than your required minimum distribution, but any additional amount increases your taxable income for that year and may raise your RMD tax burden.
Do inherited Roth IRAs have RMDs?
Yes. While Roth IRA owners aren’t required to take RMDs during their lifetime, inherited Roth IRAs must generally be emptied within 10 years of the original owner’s death, following standard RMD tax rules for beneficiaries [20].
Do RMDs apply if I’m still working and contributing to my IRA?
Yes. Even if you’re still working, RMD tax rules apply to traditional IRAs once you reach age 73. Contributions can continue if you’re eligible, but withdrawals must still meet required minimum distribution (RMD) deadlines[21].
Can RMDs push me into a higher tax bracket?
Yes. Since RMDs count as ordinary taxable income, taking a large distribution could raise your total income for the year, potentially pushing you into a higher tax bracket and increasing your overall RMD tax liability[22].
