There is no single best time of year to take your RMD. Pulling it in January protects you from missed deadlines and market drops, waiting until December buys you almost a full year of tax-deferred growth, and spreading it across the year smooths your cash flow. The right choice depends on your tax bracket, your Medicare income thresholds, whether you plan to give to charity, and how much of the money you actually need to live on.
Taking It Early in the Year
Completing the distribution in January or February locks in the dollar amount before the market has a chance to drop. If your IRA lost 15% in a spring correction, you already pocketed the cash at the higher value. That matters most when your account is heavily weighted toward stocks or other volatile assets.
Early withdrawal also builds a safety margin. Health problems, family emergencies, or plain forgetfulness in December can’t threaten your compliance when you handled the obligation months ago. Custodians process requests faster in the first quarter because they aren’t fighting year-end volume.
The cost is lost compounding. Dollars pulled in January stop growing tax-deferred for the rest of the year, and if the market rallies you’ve missed gains that would have stayed sheltered inside the IRA. One way to soften that is an in-kind transfer: instead of selling for cash, move the actual shares from the IRA to a taxable brokerage account. The fair market value on the transfer date counts as your RMD and is taxed as ordinary income, but any appreciation after that point is taxed at the lower capital gains rate when you eventually sell. You also avoid being out of the market during the days it would take to sell, transfer cash, and reinvest.
Waiting Until Year-End
Holding off until November or December keeps your money growing tax-deferred as long as possible. Eleven extra months of compounding in a rising market produces a meaningfully larger year-end balance, and you’ve deferred the tax bill to the latest possible point.
The risk is logistical. Custodians see a crush of withdrawal requests in the final weeks of December, and processing stretches. If you hold assets that aren’t immediately liquid, such as certain mutual funds with settlement periods or alternative investments, you could blow the deadline waiting for a trade to clear. Start the request no later than early December. Some custodians recommend mid-November for anything beyond a simple cash withdrawal.
The Withholding Trick That Favors December
Here’s a timing advantage experienced retirees use. Federal tax withheld from an IRA distribution is treated as paid evenly throughout the entire year, regardless of when the distribution actually happens. That means you can take a large December distribution, withhold enough to cover your full annual tax bill, and the IRS treats those withheld dollars as if you’d been making quarterly payments all along. You avoid the underpayment penalty entirely without writing a single estimated tax check.
The default federal withholding rate on a nonperiodic distribution like an RMD is 10%, but you can set any rate between 0% and 100% by filing Form W-4R with your custodian.1Internal Revenue Service. Form W-4R – Withholding Certificate for Nonperiodic Payments and Eligible Rollover Distributions If your effective tax rate is closer to 22%, the 10% default will leave you short. Review your overall tax picture before you request the distribution and adjust accordingly.
Spreading Withdrawals Across the Year
Setting up monthly or quarterly automatic distributions turns the RMD into something that resembles a paycheck. If your living expenses run $4,000 a month and your RMD works out to roughly $48,000, a monthly withdrawal covers the bills without you thinking about it. You can take the money as a lump sum, in installments, or in any combination, as long as the total for the year meets the required amount.2Internal Revenue Service. Publication 590-B – Distributions from Individual Retirement Arrangements (IRAs)
Periodic withdrawals also create a dollar-cost-averaging effect in reverse. Instead of selling your entire position at one price on one day, you sell small pieces throughout the year and receive an average price. That protects you from the bad luck of liquidating everything on a down day, though it also means you won’t capture the best possible price if the market runs hot. For most retirees, the steadier cash flow and lower stress make this the most practical approach.
How Your Tax Bracket Should Shape the Timing
The single biggest factor in when and how to take your RMD is the effect on your tax bracket. Every dollar of an RMD from a traditional IRA or 401(k) counts as ordinary income. A large distribution stacked on top of Social Security, a pension, and other income can push you into a higher marginal rate.
For 2026, the federal brackets for a single filer start at 10% on the first $12,400 of taxable income, jump to 12% up to $50,400, and reach 22% above that threshold. Married couples filing jointly hit the 22% bracket at $100,801. If your other income already puts you near a bracket boundary, even a modest RMD can tip you over.
Splitting the distribution into monthly or quarterly pieces doesn’t change your total tax for the year, because you’re taxed on the annual total either way. What splitting does help with is cash flow and preventing accidental under-withholding. The real bracket-management move happens in the years before RMDs start. If you retire at 65 and RMDs don’t begin until 73, converting traditional IRA funds to a Roth during those lower-income years fills up the lower brackets at a discount, shrinks the traditional IRA balance, and permanently reduces future RMDs. Even partial conversions of $20,000 or $30,000 a year add up over a decade.
Medicare IRMAA and the Two-Year Lookback
Medicare uses a two-year lookback to set your premiums. Income reported on your 2024 tax return determines whether you pay an Income Related Monthly Adjustment Amount surcharge on your 2026 Part B and Part D premiums. The RMD you take in 2026 won’t affect your Medicare costs until 2028.
For 2026, the first IRMAA surcharge threshold kicks in at $109,000 of modified adjusted gross income for single filers and $218,000 for married couples filing jointly.3Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles Each additional tier carries a higher monthly premium. A retiree who normally stays below the threshold but takes a large lump-sum RMD in a single year could temporarily spike income above the line and pay elevated premiums two years later. Spreading the distribution across months does not fix this, because the surcharge is based on annual income. What does help is keeping overall income below the threshold through qualified charitable distributions or Roth conversions done in earlier years.
When a Qualified Charitable Distribution Changes the Timing
If you plan to give to charity, a qualified charitable distribution changes the calendar. A QCD lets you transfer money directly from a traditional IRA to a qualifying charity. The amount counts toward your RMD but never appears as taxable income on your return.4Internal Revenue Service. Seniors Can Reduce Their Tax Burden by Donating to Charity Through Their IRA For 2026, the annual QCD limit is $111,000 per person, with up to $55,000 of that eligible for a one-time transfer to a charitable remainder trust or charitable gift annuity.
Timing matters here in a specific way. The IRS treats the first dollars out of your IRA each year as satisfying the RMD. If you take $30,000 in cash for living expenses in February and then try to make a $20,000 QCD in March, the RMD may already be fully satisfied by that February withdrawal, and the QCD won’t offset any tax on the amount you already pulled. Make the QCD before or alongside any personal withdrawals. The transfer must go directly from the custodian to the charity; if the money lands in your bank account first, even briefly, it becomes a regular taxable distribution.
QCD eligibility begins at age 70½, which is two and a half years before RMDs start at 73.5Office of the Law Revision Counsel. 26 US Code 408 – Individual Retirement Accounts A QCD that exceeds your annual RMD cannot be carried forward to reduce future years’ RMDs.2Internal Revenue Service.

The First-Year Deadline Choice
People reaching the starting age get a one-time extension: you can push your very first RMD to April 1 of the following year instead of taking it by December 31.6Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) The extension sounds generous but creates a trap. Your second RMD is still due by December 31 of that same following year, meaning two full distributions land on the same tax return. For someone with a large IRA balance, that double hit can push income into a higher bracket and trigger Medicare surcharges two years later. Most people are better off taking the first RMD in the year they reach the starting age and avoiding the pileup.
Don’t Miss December 31
Whichever timing you choose, most annual RMDs must be complete by December 31. Under SECURE Act 2.0, the starting age is 73 for anyone born between 1951 and 1959, climbing to 75 for people who turn 73 after December 31, 2032.7Congressional Research Service. Required Minimum Distribution (RMD) Rules for Original Owners One narrow exception: if you’re still working and participating in your current employer’s retirement plan, you can delay RMDs from that specific plan until the year you actually retire, unless you own 5% or more of the business.8Internal Revenue Service.

Miss the deadline and the IRS charges an excise tax of 25% on the shortfall. If you correct the mistake and withdraw the missed amount within the correction window, the penalty drops to 10%.9Office of the Law Revision Counsel. 26 US Code 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans If it happens, take the missed amount as soon as you realize the error, file IRS Form 5329, and in Part IX enter the required amount, show the shortfall, write “RC” next to the penalty line, enter zero for the penalty, and attach a brief letter explaining what went wrong and how you fixed it. The IRS grants the waiver routinely when the taxpayer corrects the shortfall promptly.
