Millions of Americans spend decades building retirement accounts, then hand a chunk of that money back to the IRS because of one missed date.
It's called a required minimum distribution, or RMD, and it forces you to start withdrawing from tax-deferred accounts once you hit a certain age.
Here's the rule in plain English: once you turn 73, you generally must pull a minimum amount out of traditional IRAs, 401(k)s, and similar plans each year.
That age moved up from 72 under a 2022 law, and it rises to 75 in 2033.
Roth IRAs are exempt, which is a big reason more savers now weigh Roth conversions before retirement.
The math works against you in a subtle way.
The IRS divides your account balance by a life-expectancy factor each year, so the amount is based on what you held at the end of the prior year.
If markets jumped, your withdrawal requirement jumps too.
If markets dropped, you may still owe the same percentage, which means selling more shares to cover it.
The penalty for missing or underpaying is steep: a 25% excise tax on the shortfall, reduced to 10% if you fix it quickly.
That's on top of the ordinary income tax you owe on the withdrawal itself.
In a rough year, a single missed calculation could wipe out months of grocery and rent budget room for a retiree on a fixed income.
There's a workaround many people never use.
You can delay your first RMD from a workplace 401(k) until the year you actually retire, if you're still working and don't own more than 5% of the company.
And your very first RMD can be pushed to April 1 of the following year, but then you'd take two in one year, possibly pushing you into a higher bracket.
Timing matters for taxes, not just penalties.
A large RMD can bump you into a higher marginal rate, make more of your Social Security taxable, and raise your Medicare Part B and D premiums through income-related surcharges.
Retirees who also give to charity sometimes use a qualified charitable distribution to satisfy part or all of the RMD directly from the account, keeping that amount out of taxable income.
The practical move is to check your account now, not in December.
Confirm your age-based start year, ask your custodian whether it can automate the distribution, and consider taking it as a monthly payment so you're not forced to sell a lump sum at a bad moment.
If you have several IRAs, you can usually total the RMDs and take the full amount from one account, but each 401(k) must be handled separately.
For households already stretched by grocery bills and rent, an unexpected tax bill is the last thing anyone needs.
A few minutes with your statements, or a fee-only advisor, can prevent a costly surprise.
The deadline doesn't care how busy your year was.
Our take: RMDs aren't a punishment, they're the bill for decades of tax deferral, and the smartest savers plan for them years in advance.
Treat the withdrawal as a scheduled expense, not a shock.

Automate it, budget the tax hit, and you keep more of what you built.
