Required Minimum Distribution (RMD): What It Is and Why It Matters

Definition

A Required Minimum Distribution (RMD) is the minimum amount of money that the U.S. government requires you to withdraw annually from most tax-deferred retirement accounts once you reach a certain age. These rules are in place to ensure that the Internal Revenue Service (IRS) can eventually collect taxes on the money that has been growing tax-deferred for years or decades.

How It Works

Think of your traditional IRA or 401(k) as a partnership with the government. You get a tax break on your contributions and the investment earnings grow without being taxed each year. In exchange, the government requires you to start taking money out at a certain point so it can be taxed as ordinary income.

The RMD calculation is straightforward. For a given year, you take your retirement account's balance from December 31 of the previous year and divide it by a life expectancy factor provided by the IRS. This factor is typically found in the IRS's Uniform Lifetime Table. The result is the minimum amount you must withdraw for that year. You are always allowed to withdraw more than your RMD.

RMD rules apply to a variety of retirement accounts, including:

• Traditional IRAs
• SEP IRAs
• SIMPLE IRAs
• 401(k) plans
• 403(b) plans
• 457(b) plans

Notably, Roth IRAs do not have RMDs for the original account owner. As of 2024, thanks to the SECURE 2.0 Act, Roth 401(k) and Roth 403(b) accounts are also exempt from RMDs during the owner's lifetime.

Key Rules and Limits

Here are the key rules and limits for RMDs in 2026:

• RMD Age: The age you must begin taking RMDs depends on your birth year, as established by the SECURE 2.0 Act.
  • If you were born between 1951 and 1959, your RMD age is 73.
  • If you were born in 1960 or later, your RMD age is 75.
• First RMD Deadline: You must take your very first RMD by April 1 of the year after the year you reach your RMD age. For example, if you turn 73 in 2026, your first RMD is due by April 1, 2027.
• Subsequent RMD Deadline: For every year after your first RMD, the deadline is December 31.
• The "Two-in-One-Year" Trap: If you delay your first RMD until the April 1 deadline, you will have to take two RMDs in that same calendar year—the one for the previous year (by April 1) and the one for the current year (by December 31). This can result in a significant increase in your taxable income for that year.
• Penalty for Failure to Withdraw: The penalty for failing to take your full RMD is steep. It is 25% of the amount you failed to withdraw. However, if you correct the mistake within a two-year "correction window," the penalty is reduced to 10%.
• Still Working Exception: If you are still employed past your RMD age and do not own more than 5% of the company you work for, you may be able to delay RMDs from your current employer's 401(k) or 403(b) plan until you retire. This exception does not apply to Traditional IRAs, SEP IRAs, or SIMPLE IRAs.

Example

Let's say Maria turns 75 in 2026. Her RMD age is 75. The balance of her Traditional IRA on December 31, 2025, was $500,000.

1. Find the Life Expectancy Factor: Maria consults the IRS Uniform Lifetime Table. For age 75, the life expectancy factor is 24.6.
2. Calculate the RMD: She divides her prior year-end account balance by this factor.
   • $500,000 / 24.6 = $20,325.20

Maria must withdraw at least $20,325.20 from her IRA by December 31, 2026. This amount will be added to her taxable income for the year.

Pros and Cons

While RMDs are a mandatory part of retirement finance, they have different implications.

Pros:

• Ensures Tax Revenue: From the government's perspective, RMDs ensure that tax-deferred savings don't escape taxation indefinitely.
• Provides Retirement Income: For some retirees, the forced withdrawal can provide a steady stream of income.

Cons:

• Loss of Tax Deferral: RMDs force you to withdraw funds and pay taxes, even if you don't need the money, ending the benefit of tax-deferred growth on that portion of your savings.
• Potential for Higher Taxes: RMDs increase your taxable income, which can push you into a higher tax bracket or affect the taxation of your Social Security benefits and Medicare premiums.
• Inflexible Timing: The mandatory nature of RMDs can force you to sell investments at an inopportune time, such as during a market downturn.

Common Mistakes to Avoid

• Forgetting to Take the RMD: This is the most common and costly mistake due to the significant penalty. Setting up automatic withdrawals with your financial institution can help prevent this.
• Miscalculating the Amount: Using the wrong account balance (it must be the December 31 balance of the prior year) or the wrong life expectancy factor can lead to taking an incorrect RMD.
• Incorrectly Aggregating RMDs: You can calculate the RMD for each of your Traditional IRAs separately, add them together, and then take the total amount from just one or a combination of your IRAs. However, this rule does not apply to 401(k)s or 403(b)s. For those accounts, you must calculate and take a separate RMD from each one.
• Ignoring the Second RMD: People who delay their first RMD until April 1 of the following year sometimes forget they still need to take their second RMD by December 31 of that same year.
• Misunderstanding Inherited Account Rules: The rules for RMDs on inherited accounts are complex and changed significantly with the SECURE Acts. Most non-spouse beneficiaries are now required to empty the inherited account within 10 years of the original owner's death.

Frequently Asked Questions

Q: Do I have to take RMDs from my Roth IRA?

A: No. Roth IRAs are not subject to RMDs during the lifetime of the original account owner. This is a significant advantage of Roth accounts, as the funds can continue to grow tax-free for your entire life. However, beneficiaries who inherit a Roth IRA are typically subject to RMD rules, often requiring the account to be fully distributed within 10 years.

Q: What if I don't need the money from my RMD?

A: Even if you don't need the funds for living expenses, you must still take the withdrawal. One popular strategy for those who are charitably inclined and are age 70½ or older is the Qualified Charitable Distribution (QCD). A QCD allows you to donate up to $111,000 in 2026 directly from your IRA to a qualified charity. This amount can count towards your RMD for the year and is excluded from your taxable income, offering a powerful tax-planning opportunity.

Q: Can I just reinvest my RMD back into my IRA?

A: No, you cannot roll over your RMD into another tax-advantaged retirement account. The withdrawn RMD amount is considered a final distribution for that year. You can, however, invest the money in a regular taxable brokerage account after you have withdrawn it and paid the necessary taxes.
