Required minimum distributions are the government way of finally collecting tax on money you deferred for decades. Once you reach a certain age, the IRS requires you to withdraw a minimum amount each year from most tax-deferred retirement accounts, whether you need the cash or not. Miss the deadline and the penalty is steep. Understanding the mechanics ahead of time saves both tax and stress. This is general information, not financial or tax advice — confirm your own figures with a professional.
What changed in 2026
- The starting age is 73. SECURE 2.0 raised the RMD age to 73, and it is scheduled to rise to 75 later this decade, so confirm the age that applies to your birth year.
- The missed-RMD penalty was reduced. The old 50 percent excise tax was cut to 25 percent, and to 10 percent if corrected promptly — still a penalty worth avoiding entirely.
- Roth 401(k)s no longer require lifetime RMDs. Roth accounts inside employer plans were brought in line with Roth IRAs, which have never required distributions during the owner life.
Which accounts require RMDs
RMDs apply to most tax-deferred accounts: traditional IRAs, SEP and SIMPLE IRAs, and traditional 401(k), 403(b), and 457(b) plans. Roth IRAs never require distributions during the owner lifetime, and as of the recent rule change, neither do Roth 401(k)s. The distinction matters because it shapes which accounts to draw down first.
How the amount is calculated
The formula is mechanical: take the account balance as of December 31 of the prior year, then divide by a life-expectancy factor from the IRS Uniform Lifetime Table. A larger balance or a younger age means a smaller required fraction; the percentage you must withdraw rises each year as the factor shrinks.

Because the withdrawn amount is generally taxed as ordinary income, a large RMD can push you into a higher bracket — which is why the tax treatment of your other income, including qualified versus ordinary dividends, is worth planning around the same time.
Common pitfalls
The first RMD has a special quirk: you may delay it until April 1 of the year after you turn 73, but doing so stacks two RMDs into one tax year, often a costly mistake. Another trap is assuming your plan calculates it for you — the responsibility is yours, and errors are penalized on you. Finally, if you hold several IRAs, the rules on aggregating withdrawals differ from those for 401(k)s, so do not assume one method covers everything.
FAQ
When do I have to take my first RMD?
Generally by December 31 of the year you turn 73, though the very first one can be delayed to April 1 of the following year. Delaying stacks two into one year, so weigh the tax hit.
What happens if I miss it?
You owe an excise tax on the shortfall — 25 percent, reduced to 10 percent if you fix it quickly. It is entirely avoidable by taking the full amount on time.
Can I avoid RMDs?
Roth IRAs and now Roth 401(k)s have no lifetime RMDs. Some retirees also use qualified charitable distributions to satisfy an RMD without adding taxable income; confirm eligibility first.
Are RMDs taxed?
Withdrawals from traditional accounts are generally taxed as ordinary income. That is the whole point — the tax was deferred, not forgiven.
Where to go next
Plan the rest of your retirement income alongside this: compare Social Security claiming strategies, keep costs low with portfolio rebalancing, and learn the tax split between qualified and ordinary dividends.
