Required minimum distributions have a reputation problem.
Most people hear "RMD" and think of a dusty IRS rule that only matters at the very end of a long career.
In 2025, that assumption is costing some retirees real money.
Here's the core mechanic: once you hit your required beginning date, the government forces you to withdraw a minimum amount from tax-deferred accounts like traditional IRAs and 401(k)s each year.
You don't get to skip it because markets are down or because you'd rather let it compound.
The IRS wants its tax revenue, and it wants it on schedule.
The age threshold moved under the SECURE 2.0 Act.
If you turned 72 after 2022, your starting point is now 73.
Anyone born in 1960 or later waits until 75.
That two- or three-year gap sounds minor, but it's a meaningful window for Roth conversions and other tax planning that can lower future RMDs.
The math behind the penalty is what gets people's attention.
Miss a distribution and the IRS can take 25% of the shortfall, dropping to 10% if you correct the mistake within a correction window and file the right form.
On a $20,000 missed withdrawal, that's a $2,000 to $5,000 hit for a paperwork lapse.
Several details trip up even careful savers.
If you own multiple traditional IRAs, you calculate each one separately but you can take the total from any combination of them.
Workplace 401(k)s don't work that way — each plan stands alone, so you can't satisfy one account's obligation from another.
The first-year deadline is the one most people fumble.
You must take your initial RMD by April 1 of the year after you turn 73.
That sounds generous, but it means taking two distributions in the same calendar year, which can push you into a higher bracket, inflate your Medicare income-related premium surcharge, and shrink what you keep after taxes.
Roth IRAs never carry a lifetime RMD for the original owner.
That single exemption is why so many advisors now build Roth conversion ladders in the years before distributions kick in.
Paying tax now at a known rate beats paying later at an unknown one, especially for retirees with pensions or large balances.
Inherited accounts follow their own timeline.
Most non-spouse beneficiaries now face a 10-year window to empty the account, and annual distributions may be required along the way depending on the rules that apply to them.
Spouses get more flexibility, but they still have elections to make.
Retirees who don't need the cash have options beyond cashing out.
Qualified charitable distributions let you send up to $108,000 per year directly to charity, and that amount can count toward your RMD while staying out of taxable income.
For anyone charitably inclined, it's often the cleanest move available.
The practical takeaway is that RMD planning is a year-round exercise, not an April scramble.
Check your required beginning date, confirm whether each account is subject to its own calculation, and set a calendar reminder well before December 31.
Automating the withdrawal removes the single biggest cause of penalties: forgetting.
The bigger picture is that RMDs are less a tax event and more a forced income decision.
Once the government dictates when money leaves your account, your control shifts to how you manage brackets, premiums, and beneficiaries around it.
Final Thoughts
Treating that as a one-time chore is how retirees hand over more than they owe.
