The Hidden Cost of Delaying RMDs

The Hidden Cost of Delaying RMDs

November 09, 2025

When Congress passed the SECURE 2.0 Act, one of the headline changes was pushing back Required Minimum Distributions (RMDs) again, to age 73 now, and eventually 75 in 2033. On the surface, that sounds like a win for retirees: more time for assets to grow tax-deferred, and fewer forced withdrawals.

But like most things in financial planning, the story isn’t that simple.

Delaying RMDs can actually increase your lifetime tax bill if you’re not careful. Here’s why: as those untouched accounts keep growing, so does your future tax liability. By the time RMDs finally begin, the required withdrawals can be much larger, potentially pushing you into higher tax brackets, triggering IRMAA surcharges on Medicare premiums, or increasing the taxable portion of your Social Security benefits.

That’s why smart retirees should treat the RMD delay as a planning window, not a free pass. The years between retirement and your first RMD are often the best time to do things like Roth conversions, qualified charitable distributions, or strategic partial withdrawals that smooth out taxes over time.

The new law also offers a bit of relief if you make a mistake: the penalty for missing an RMD has dropped from 50% to 25%, or 10% if corrected quickly. That’s good news, but it’s not an excuse to ignore the rules. The IRS still expects those distributions on schedule once you’re subject to them.

So yes, later RMDs can be a gift, but only if you use the extra time wisely. For many retirees, the right move isn’t to delay as long as possible; it’s to start drawing down strategically before you’re required to.

The best financial plans don’t just minimize taxes in any given year; they minimize them across decades. That’s the real goal of smart retirement income planning.
