Millions of Americans over 73 are about to get a letter or a nagging email from their brokerage.
It's a reminder that the IRS wants its cut of your retirement account, whether you need the money or not.
The rule is called a required minimum distribution, or RMD.
Once you hit a certain age, you can't just let your 401(k) or traditional IRA sit there compounding forever.
You have to withdraw a minimum amount each year, and that withdrawal lands on your tax return as ordinary income.
That timing matters more than most people realize.
A retiree who doesn't need the cash still gets the tax bill, and that extra income can nudge Social Security benefits into the taxable zone or push Medicare premiums higher through IRMAA surcharges.
Two years later, the premium hike shows up, often surprising people who thought their taxes were settled.
Divide your account balance at the end of the prior year by a life expectancy factor the IRS publishes.
At 73, that factor is about 26.5, so a $500,000 balance means roughly $18,900 must come out.
Miss the deadline and the penalty is 25% of the amount you should have taken, dropping to 10% if you fix it quickly.
On a $20,000 missed withdrawal, that's $5,000 gone, or $2,000 if corrected fast.
The IRS has waivers, but they require paperwork and a plausible excuse.
Roth IRAs are exempt during the owner's lifetime, which is one reason conversions get so much attention right now.
Many retirees don't need the full distribution for groceries and rent, so they reinvest it in a taxable brokerage account.
That creates a second layer of taxes on dividends and gains down the road.
Others use the forced cash to pay down credit card debt or cover rising insurance premiums, which at least puts the money to work.
The strategy most advisors push is a qualified charitable distribution.
If you're 70½ or older, you can send up to $108,000 directly from an IRA to charity in 2025, and that amount counts toward your RMD without ever hitting your taxable income.
For retirees who already give, it's close to free money in tax terms.
For everyone else, the move is to plan the withdrawal early in the year rather than scrambling in December.
Check whether your brokerage offers automatic distributions, and confirm the total actually satisfies the requirement if you hold multiple IRAs.
Each account has its own calculation, but the total can usually be taken from any one of them.
One more wrinkle: the first RMD deadline can be deferred to April 1 of the following year, but that means two distributions in the same tax year.
That double-up can spike your bracket and your Medicare premiums.
Most people are better off taking the first one on schedule.
The bottom line is that an RMD isn't really about retirement income.
It's about the government collecting deferred taxes on money you sheltered decades ago.
Final Thoughts
Treat it as a tax event to plan around, not a windfall to spend, and the surprise factor drops fast.
