What Is a Required Minimum Distribution (RMD)?
RMDs refer to the minimum amounts that the Internal Revenue Service (IRS) mandates you withdraw each year from tax-deferred retirement accounts, such as SEP-IRAs, traditional IRAs, SIMPLE IRAs, and 401(k) plans. Roth IRAs, are excluded from this condition, and in 2024, all Roth accounts (including Roth 401(k)s will be RMD-exempt.
Because RMD withdrawals are taken from tax-deferred accounts, the distributions are subject to income tax.
According to the Secure 2.0 Act, the account owner needs to begin withdrawing RMD amounts on a set schedule: the first distribution must be taken by April 1st of the year following the year you turn 73 or retire, whichever is later.
Calculating your RMD involves considering various factors, such as the account balance at the end of the previous year, the account holder’s age, and the IRS-provided life expectancy tables.
Why are RMDs Required?
RMDs are mandated by the IRS to ensure that retirees begin to withdraw—and thus pay taxes on—accumulated funds in their tax-deferred retirement accounts. It also ensures that investors won’t be able to use their retirement savings for endless tax-free growth.
RMD withdrawals are considered taxable income and can potentially affect your year-end tax bracket. One of the consequences of neglecting to take RMDs is facing steep penalties from the IRS.
As of 2023, and due to the Secure Act 2.0, the penalty imposes an excise tax of 25% on the required amount for the distribution period that failed to be withdrawn. You can knock this penalty down to 10% if you take the RMD within the “correction window”, or two years.
We will explore how RMDs are calculated more in the next section, but it’s important to know that your RMD will vary each calendar year according to the life expectancy table provided by the IRS.
Your RMD is contingent on your account balance (after distributions from the previous year) and in consideration of your projected life expectancy. You’ll receive notice of impending RMD in your first year of eligibility so that you can plan account distributions accordingly for that tax year.
Understanding potential tax implications and penalties associated with RMDs is vital to making informed retirement planning decisions.
Calculating RMDs for 401(k) Plans
Having a solid grasp on how RMDs are calculated is a crucial step in avoiding penalties and securing a successful retirement. To help retirees with this, the IRS provides life expectancy tables in IRS publication 590-B. These come in three types:
- The Uniform Lifetime Table: Used for all unmarried account owners, married owners with a spouse ten or fewer years younger, and married owners with a beneficiary who isn’t their spouse.
- The Joint Life and Last Survivor Expectancy Table: for owners with a spouse over ten years younger who serves as the account’s sole beneficiary.
- The Single Life Expectancy Table: for beneficiaries who aren’t the account owner’s spouse.
The applicable life expectancy factor will depend on various factors such as the account owner’s age, the beneficiary status, and whether the account beneficiary is a spouse.
To work out your RMDs using the IRS tables, here’s a simplified process:
- Find your account balance as of December 31st of the previous year.
- Identify the relevant life expectancy factor from the IRS table (Publication 590-B).
- Divide the account balance by the life expectancy factor.
If you have multiple tax-deferred retirement accounts, you must calculate this separately for each account and meet the separate RMD requirements.
- Here’s an example: Suppose an unmarried account owner is 73. They’ll use the Uniform Lifetime Table, which indicates that the distribution period at that age is 26.5. If they had $100,000 in their 401(k) at the end of the previous year, their RMD for that year is $3,774. This number would increase if they had more retirement savings.
- With $300,000 in their account, the RMD would be $11,321 at 73. Or, if they had $300,000 but were older when they retired — let’s say 80 — their RMD would be $14,851.
