2026 RMD Age Rules Update

When does the IRS finally come collecting on the taxes you deferred for thirty years? Later than it used to, and the penalty for getting it wrong is no longer brutal. SECURE 2.0 pushed the required minimum distribution start age back and slashed the missed-RMD penalty, and 2026 is a good year to know exactly where you stand.

A required minimum distribution is the slice of your tax-deferred accounts the government forces you to withdraw each year, whether you need the cash or not. Traditional IRAs and most workplace plans. Every dollar lands on your tax return as ordinary income.

Your start age depends on your birth year

There’s no single RMD age anymore. It’s tied to when you were born:

• Born 1951 to 1959: RMDs start at 73.
• Born 1960 or later: RMDs start at 75.

That later start is a gift, and most people waste it. The years between when you retire and when RMDs begin are the lowest-income years you’ll ever have, the quiet window before forced withdrawals and Social Security stack up. Push the start to 75 and you get more of that window, not less.

The penalty got a lot less scary

Miss an RMD and the old penalty was a savage 50% of what you should have taken. SECURE 2.0 cut it to 25%, and down to 10% if you fix the shortfall promptly, generally within two years.

That’s real relief, but don’t read it as permission to be sloppy. Even 10% on a missed six-figure distribution is a self-inflicted wound. The rule rewards people who catch the mistake fast and file to correct it.

The part most people miss

Here’s the trap inside the good news. You can defer your very first RMD to April 1 of the year after you turn on. It sounds like a free pass. It isn’t.

Take that deferral and you land two RMDs in a single calendar year, the delayed first one plus the on-time second one. Two forced withdrawals stacked into one tax return can shove you into a higher bracket and, two years later, spike your Medicare premiums through IRMAA, the income-based surcharge. The “free” deferral often costs more than taking the distribution on time.

What to do about it

If you’re in the low-income window before RMDs hit, use it. Roth conversions in those years shrink the balance that gets divided once RMDs begin, which shrinks every forced withdrawal for the rest of your life. Once RMDs start, a qualified charitable distribution sends money straight from your IRA to charity and keeps it off your return entirely.

The RMD is rare among tax bills. It tells you the year it’s coming and the formula it’ll use, decades in advance. The later start age and softer penalty buy you room. The whole game is to use that room before the forced withdrawals start, not after.
