Millions of Americans spend decades building a retirement account, carefully watching it grow, only to hit a surprise tax bill the moment they turn 73.
That surprise has a name: the required minimum distribution, or RMD.
It's the IRS rule that forces you to start pulling money out of tax-deferred accounts like traditional IRAs and 401(k)s, whether you need the cash or not.
Once you reach RMD age, the government calculates a minimum amount you must withdraw each year based on your account balance and life expectancy.
Skip it, and the penalty is steep — a 25% excise tax on the amount you should have taken, dropping to 10% if you fix it quickly.
That's real money vanishing for a paperwork mistake.
The age moved recently, and that's where a lot of people get tripped up.
The SECURE 2.0 Act pushed the starting age to 73 for most retirees, with another bump to 75 scheduled for 2033.
If you turned 72 before 2023, your old start date may still apply.
Getting this wrong in either direction can mean an unnecessary penalty or an unplanned tax hit.
The sneaky part is what RMDs do to your tax bill.
Withdrawals from traditional accounts count as ordinary income, which can push you into a higher bracket, raise your Medicare Part B and Part D premiums through IRMAA surcharges, and even make more of your Social Security taxable.
A retiree who thought they were in a comfortable low-tax lane can suddenly owe thousands.
You generally have until Dec. 31 each year to take your RMD, with one exception: your very first withdrawal can be delayed until April 1 of the following year.
That sounds generous, but taking two RMDs in one calendar year can spike your income and trigger those same surcharges.
Many advisors tell clients to just take the first one on time.
There are a few legal ways to soften the blow.
Qualified charitable distributions let you send up to $105,000 per year directly from an IRA to charity, and that money counts toward your RMD without landing on your taxable income.
Roth conversions done in your low-income years can shrink future RMDs, though you'll owe tax at conversion time.
And if you're still working past 73, a workplace 401(k) at your current employer may be exempt from RMDs until you retire.
Most non-spouse beneficiaries now must empty the account within 10 years under the SECURE Act, and annual RMDs may apply along the way depending on the heir's situation.
The rules here are genuinely tangled, and the IRS has been issuing reminders as compliance catches up.
The bottom line is that an RMD isn't optional, and ignoring it is one of the more expensive oversights in personal finance.
Check your account balances each year, confirm your start date, and consider automating the withdrawal so a busy December doesn't cost you a quarter of what you owed.
Final Thoughts
If your situation involves multiple accounts or an inheritance, a one-time session with a tax professional can easily pay for itself.
