Required Minimum Distributions: Rules, Calculations, and Strategies

The Government Eventually Wants Its Tax Money — On Your Schedule

Tax-deferred retirement accounts — traditional IRAs, 401(k)s, 403(b)s, and similar plans — allow investments to grow without annual taxation. That deferral is not permanent. Congress mandated Required Minimum Distributions (RMDs) to ensure that retirement accounts don't become permanent tax-avoidance vehicles. Starting at a specific age, account holders must withdraw a minimum amount each year and pay income tax on those withdrawals. Missing RMDs triggers one of the steepest penalties in the tax code.

When RMDs Begin: SECURE 2.0 Changes

The SECURE 2.0 Act of 2022 raised the RMD starting age significantly:

• Born 1950 or earlier: RMDs began at age 72
• Born 1951–1959: RMDs begin at age 73
• Born 1960 or later: RMDs begin at age 75

Your first RMD can be delayed to April 1 of the year following the year you reach your RMD age. All subsequent RMDs must be taken by December 31 of each year. Taking the first RMD in the following year means two RMDs that year — which can push taxable income into higher brackets. Most advisors recommend taking the first RMD in the year it's due to avoid this income stacking.

Which Accounts Require RMDs

How RMD Amounts Are Calculated

Each year's RMD = Prior December 31 account balance ÷ IRS Life Expectancy Factor

Life expectancy factors come from the IRS Uniform Lifetime Table (most account owners) or Joint Life and Last Survivor Table (if sole beneficiary is a spouse more than 10 years younger). Example calculation:

• Account balance on December 31 of prior year: $500,000
• Account holder age: 75
• Uniform Lifetime Table factor at age 75: 24.6
• RMD = $500,000 ÷ 24.6 = $20,325

If you own multiple traditional IRAs, calculate the RMD for each separately, then take the total from any combination of those IRAs. For 401(k) and other employer plans, each plan's RMD must be taken from that specific plan.

Penalty for Missing RMDs

The penalty for failing to take a required RMD was historically 50% of the amount that should have been withdrawn — one of the harshest penalties in the tax code. SECURE 2.0 reduced this to 25% starting in 2023, and further to 10% if the shortfall is corrected within two years. Even so, a missed $20,000 RMD carries a potential $2,000–$5,000 penalty on top of the income tax owed. The IRS does have a correction process for inadvertent failures.

Strategies to Manage RMD Tax Impact

Roth Conversions Before RMDs Begin

Converting traditional IRA funds to Roth IRA during the years between retirement and RMD age (the "gap years") reduces future RMD size. Smaller traditional IRA balances generate smaller mandatory withdrawals, providing more control over taxable income in later years. The optimal amount to convert each year fills up a lower tax bracket without pushing into higher rates.

Qualified Charitable Distributions (QCDs)

Taxpayers age 70½ or older can transfer up to $105,000 per year (2024, inflation-adjusted) directly from a traditional IRA to a qualifying charity — a Qualified Charitable Distribution. The QCD satisfies all or part of the RMD requirement. The distribution is excluded from gross income entirely (neither reported as income nor deductible as a charitable contribution). For retirees who donate to charity, this is almost always the optimal method — it reduces AGI, potentially reducing Medicare Part B premiums and Social Security taxation.

Still Working Exception

If you are still employed at the age when RMDs begin and do not own more than 5% of the company, you can delay RMDs from your current employer's 401(k) until April 1 following the year you retire. You cannot delay RMDs from IRAs or previous employers' plans using this exception.
