A required minimum distribution, or RMD, is the amount the IRS forces you to withdraw each year from a tax-deferred retirement account once you reach a certain age, whether or not you actually need the cash. The rule exists because Traditional accounts defer tax on the way in, and the government eventually wants its share — RMDs are how it makes sure that happens on a schedule rather than never. The age trigger, the calculation, and the penalty for getting it wrong are all fixed by formula, which makes RMDs one of the more mechanical parts of retirement planning.
What changed in 2026
- The RMD starting age sits at 73 for most current retirees, part of a phased increase — it rises to 75 for those born in 1960 or later, under a schedule set by recent retirement legislation.
- Roth 401(k) and Roth 403(b) accounts no longer require RMDs during the owner's lifetime, matching the treatment Roth IRAs have always had — a meaningful change from just a few years ago.
- The penalty for a missed RMD dropped from a historical 50% excise tax to 25%, and further to 10% if corrected within a defined correction window.
- Qualified charitable distribution limits continue adjusting for inflation, keeping the direct-to-charity strategy relevant for owners who do not need the income.
How the amount is calculated
Your RMD is not a guess — it is a formula. Take your account balance as of December 31 of the prior year, divide it by a life-expectancy factor from the IRS Uniform Lifetime Table that corresponds to your age, and the result is the minimum you must withdraw that year.
A hypothetical example: a $500,000 Traditional IRA balance at the end of the prior year, with a life-expectancy factor of roughly 26.5 for a 73-year-old, produces an RMD of about $18,868 for the year. The factor shrinks as you age, so the required percentage of the account rises each year even if the balance stays flat.
Multiple Traditional IRAs can have their RMDs calculated separately but withdrawn from any one or a combination of them. Multiple 401(k)s from different employers do not get that flexibility — each plan's RMD must generally be withdrawn from that specific plan.
Planning around your RMDs
- Convert to Roth before RMD age. Money moved to a Roth IRA in your 60s shrinks the future Traditional balance that RMDs are calculated from; a Roth conversion ladder is one structured way to spread that out over several years.
- Use qualified charitable distributions if you give to charity anyway. Sending money directly from a Traditional IRA to a qualified charity can count toward the RMD while excluding that amount from taxable income.
- Take the first RMD in the year you turn 73, rather than delaying, to avoid stacking two taxable distributions into one calendar year.
- Watch the effect on Medicare premiums and Social Security taxation. A large RMD can push other income thresholds higher in ways that are easy to miss when only looking at the withdrawal itself.
Common mistakes
Missing the first-year delay trap. The very first RMD can be delayed to April 1 of the following year, but doing so means two RMDs land in that same calendar year — potentially pushing you into a higher tax bracket than spreading them out would have.
Assuming a Roth 401(k) still requires RMDs. That was true before a recent rule change; Roth workplace accounts now follow Roth IRA treatment and are exempt from lifetime RMDs.
Forgetting inherited account rules differ. Most non-spouse beneficiaries face a different, often faster, distribution timeline than the original owner did — do not assume the same formula applies.
Ignoring qualified charitable distributions. Donating directly from a Traditional IRA to a qualified charity can satisfy some or all of an RMD while excluding that amount from taxable income — a straightforward way to reduce the tax hit if giving is already part of the plan.
FAQ
What happens if I miss an RMD?
The shortfall is subject to a 25% excise tax, reduced to 10% if you correct it within the IRS's correction window — take the missed distribution and file the appropriate form as soon as you catch the error.
Do Roth IRAs have RMDs?
No, never, during the original owner's lifetime. That has been the rule since Roth IRAs were created.
Can I reduce my future RMDs?
Roth conversions before RMD age move money out of the accounts subject to RMDs entirely — see Roth conversion ladder explained for 2026 for one structured way to do that over several years.
Do I need to take an RMD from every retirement account I own?
From every Traditional-type account subject to RMDs, yes, though IRAs can be aggregated for withdrawal purposes while separate employer plans generally cannot.
