Required Minimum Distributions for IRAs

How much do you need to take out of your IRA this year? Here's what you need to know.

By Matthew Frankel, CFP – Updated Jan 9, 2023 at 8:16PM

If you have savings in a traditional IRA, you're required to start taking withdrawals, known as required minimum distributions, or RMDs, after you reach 72 years of age.

In other words, while IRAs let you save and invest for retirement on a tax-deferred basis, the IRS doesn't just let you defer paying tax indefinitely on your retirement savings -- eventually it wants to get paid. Here's how RMD rules work, and how to calculate your RMD each year.

What is an RMD?

RMD stands for required minimum distribution. If you have savings in tax-deferred retirement accounts, such as a 401(k) or traditional IRA, you are required to begin taking distributions (withdrawals) from your account after you reach age 72. 

The RMD rules only apply to tax-deferred retirement accounts. After-tax retirement accounts are not subject to the required minimum distribution rules. So, if you have a traditional IRA, you'll need to start taking RMDs when you reach 72. On the other hand, if you have a Roth IRA, you don't have to take any RMDs, no matter how old you get. You can leave your Roth IRA investments alone to grow tax-free for as long as you'd like.

How your IRA RMD is determined each year

Your RMD is calculated each year once you reach age 72 and depends on two main variables -- your account balance and your age.

Using one of two IRS life expectancy tables, you can find the expected distribution period that you'll use to calculate your RMD. Most people use the Uniform Lifetime Table, but if your IRA's sole beneficiary is your spouse who is more than 10 years younger than you, you'll use the Joint Life and Last Survivor Table instead. You can use the IRS' worksheet and reference tables (in Appendix B) to help calculate your RMD. 

Using your account value -- which is defined as the value of your account at the end of the previous calendar year -- divide by your distribution period to determine your RMD. For example, if you have $500,000 in your traditional IRA at the end of 2022, and you're 75 years old, the Uniform Lifetime Table gives an expected distribution period of 24.6 years. Dividing your account's balance by this number shows a 2022 RMD of $20,325. 

For a quick reference, here are the current life expectancy factors from the Uniform Lifetime Table for retirees age 72 through 92.

Age Distribution Period Age Distribution Period Age Distribution Period

73 26.5 80 20.2 87 14.4
74 25.5 81 19.4 88 13.7
75 24.6 82 18.5 89 12.9
76 23.7 83 17.7 90 12.2
77 22.9 84 16.8 91 11.5
78 22.0 85 16.0 92 10.8

What if you have more than one account to take an RMD from?

Since many people who have a traditional IRA also have an employer-sponsored retirement plan such as a 401(k), it's important to discuss what you need to do in this situation.

The short answer is that it doesn't matter which account you take your RMD from, as long as you withdraw enough to satisfy the RMDs for all of your accounts.

For example, if you calculate that you need to take a $15,000 RMD from your traditional IRA and $10,000 from your 401(k), the IRS doesn't require you to take these dollar amounts out of the corresponding accounts. As long as you take a total of $25,000 out of your tax-deferred retirement accounts during the year, you've met the IRS' requirement.

When do you need to take your RMD?

In general, you need to fulfill your RMD obligation by Dec. 31 each year.

The exception is the year in which you turn 72, when you have until April 1 of the following year to take your first RMD. In other words, if you reached age 72 in September 2022, you'll have until April 1, 2023 to take your first RMD.

A word of caution -- if you wait until the last minute to take your first RMD, you'll also have to take your second RMD by the end of the same calendar year, resulting in two RMDs in the same year. Since withdrawals from these retirement accounts are counted as taxable income, waiting until the last minute could catapult you into a higher tax bracket and therefore result in a higher-than-expected tax bill.

As a final thought, under no circumstances should you not take your RMD in any given year. The IRS penalty for not doing so is harsh. If you fail to take your entire RMD, you'll be assessed a penalty equal to 50% of the amount you didn't withdraw. So, make sure you know how much you're required to withdraw, and then withdraw it in a timely manner.
