Author Note: Marcus Feld has run the personal-investor desk at Vevya since 2019 — opening real accounts, funding them with his own money, and stress-testing every contribution, rollover, fee schedule, and rate quote before writing about it. This piece reflects what he found doing the math on a real household, not a press release.
Every year, one of the most confident-sounding pieces of retirement advice I hear is also one of the most quietly expensive: just take the RMD and nothing more. The IRS sets a minimum, the logic goes, so the minimum is the plan. Contrary to popular belief, the required minimum distribution is a floor, not a target — and the space above the floor is where most of the actual 2026 retirement tax planning lives.
I’ve tracked RMD season since 2019, and 2026 is the first year the new start-age schedule is fully in force for a big birth cohort. Everyone born in 1953 turns 73 this year, so a large wave of first-time RMD filers faces a December 31, 2026 deadline — with the option to push their very first distribution to April 1, 2027, a decision that carries a double-distribution trap most people never read about. When I priced this out on a real household balance, comparing “just take the minimum” against a plan that uses the doors above the floor, the gap was bigger than I expected. This piece walks through the 2026 numbers: the divisor table, the rising withdrawal rate it implies, the $111,000 qualified charitable distribution that can make an RMD completely tax-free, and the penalty rules most people still describe with the old 50% figure.
First, the part most people get wrong: the start date
You’ll hear three different RMD start ages floating around — 70½, 72, 73. All of them are old. Under SECURE 2.0, the rules are now strictly by birth year:
Birth years 1951 through 1959: your RMDs start at age 73. Birth year 1960 or later: your RMDs start at age 75. That’s the whole rule for starting, and it’s worth writing on a calendar now: the first RMD deadline for the 1953 cohort is December 31, 2026 — not 2027, not “next tax season.”
There is one exception to the deadline: for the first RMD only, you may delay taking it until April 1 of the following year. If you turn 73 in 2026, you can wait until April 1, 2027 — but every RMD after that, including your 2027 RMD, is due by December 31 of its own year.
The double-distribution trap
Here’s the part most RMD explainers skip: if you use the April 1 grace period, you do not get to spread your first two distributions across two tax years. You take both in one — your 2026 RMD (taken in early 2027) and your 2027 RMD (due December 31, 2027) both land on a single 2027 return, often right when Social Security and any pension start landing too.
In my analysis, the April 1 delay is a legitimate move only as a deliberate bracket-management tool — if you’re confident your 2026 income is low enough that taking the first RMD in 2026 would trip a threshold, and you’d rather take both in a lower-income 2027. If you don’t have that specific plan, taking the first RMD by December 31, 2026 is the cleaner default. The delay is a choice, not a free option, and most people treat it like a free option.
One more start-date wrinkle: IRAs have no delay whatsoever — if you’re old enough, your IRA RMD is due. But if your pre-tax money is in a 401(k) and you’re still working at your original employer, you can postpone that plan’s RMDs until the year after you separate from service, unless you’re a more-than-5% owner of the business. That’s the only real “pause button” in the system, and it applies to the workplace plan only, never to IRAs.
The formula is one division — and the number gets bigger every year
The RMD itself is the simplest calculation in all of retirement. You take your account balance as of December 31 of the prior year and divide it by your distribution period from the IRS Uniform Lifetime Table — the same table the IRS has used for years, unchanged for 2026. RMD equals prior year-end balance divided by the divisor for your age. That’s it. No income, no expenses, no planning — just arithmetic. And the uncomfortable truth is that the arithmetic is doing something nobody likes: your withdrawal rate climbs every single year. At 73, the divisor is 26.5, which means you must withdraw about 3.77% of your year-end balance. At 75 it’s 24.6, about 4.07%. At 80 it’s 20.2, about 4.95%. At 90 it’s 12.2, about 8.2% of whatever is left. The table assumes you live a long time, so the IRS keeps pulling a bigger slice off the pie as your remaining life expectancy shrinks. In my own accounts, I watch that percentage creep up a little every year, and it’s the quiet reason “just take the RMD” strategies get painful in a retiree’s ninth or tenth year of distributions.
The divisors you actually need for 2026
Here’s the slice of the Uniform Lifetime Table covering the realistic range for the 1953 cohort, with the implied withdrawal rate on the right. (The full table runs to age 120 and up.)
| Age in 2026 | Divisor | Implied withdrawal rate | RMD on a $500,000 12/31/2025 balance |
|---|---|---|---|
| 73 (turns 73 in 2026) | 26.5 | about 3.77% | $18,868 |
| 74 | 25.5 | about 3.92% | $19,608 |
| 75 | 24.6 | about 4.07% | $20,325 |
| 78 | 22.0 | about 4.55% | $22,727 |
| 80 | 20.2 | about 4.95% | $24,752 |
| 85 | 16.0 | about 6.25% | $31,250 |
| 90 | 12.2 | about 8.20% | $41,000 |
Two rules about the inputs, because both cause real mistakes. First, the balance is the one at the end of the prior year, not today’s balance, and you use your age as of your birthday in the distribution year. Second, if you have the same kind of account at more than one custodian (three IRAs, say), you can take the full combined RMD from a single account — but you still have to compute each account’s RMD separately and keep a worksheet, or the IRS can treat the untaken account as a shortfall. I’ve seen people who moved mid-year and lost track of one account’s number; the worksheet habit is cheap insurance.
The 2026 math, run on a real household
When I priced this out, I used a household I track in my analysis: a single retiree, $740,000 in a traditional IRA at year-end 2025, turning 73 in 2026, in the 22% federal bracket, with a standing plan to give $15,000 a year to charity either way. Two scenarios, both taking only the required minimum, one routing it through a qualified charitable distribution.
Scenario A — take the minimum, pay tax on it: the 2026 RMD on $740,000 at the 73 divisor is $27,925. At 22%, that’s roughly $6,143 of tax on the first year’s distribution alone. Projected forward ten years with 5% growth, the RMD climbs from $27,925 to about $41,300 by age 82 — that’s the divisor table doing its work, from 26.5 down to 18.5 — and the ten-year total of distributions is about $343,600, with total income tax on those distributions of roughly $75,600.
Scenario B — take the minimum, but send $15,000 of it straight to charity as a QCD: the distribution is identical in size, but the $15,000 never counts as taxable income. Same horizon, same growth assumption, the tax bill drops to roughly $42,600. The charity got the same $15,000 every year in both scenarios. The difference is about $33,000 in federal tax over a decade — money that stays in the IRA and keeps compounding. In my own accounts, this is the single highest-ROI line item in any 70+ tax plan, and it’s almost never discussed outside of tax seminars.
What nobody is discussing: the QCD is a tax shield you can’t use on the tax return
The qualified charitable distribution works only if the money moves directly from the IRA to the charity — the check must come from the custodian, not from your bank account after you’ve cashed the distribution out. If you withdraw first and then donate, you’ve already got the income, and the charity deduction is subject to AGI limits that a 70-and-over retiree often can’t fully use. Done correctly, the QCD reduces the RMD dollar-for-dollar and AGI dollar-for-dollar — and, a point that matters more than people think, it never makes itemizing more attractive, because QCDs are not itemized at all.
Three limits to keep straight. You must be at least 70½ — a rule that predates the new start ages and is independent of them. The 2026 per-person cap is $111,000, indexed for inflation since SECURE 2.0. And QCDs work only from IRAs — a 401(k) can’t do one while the money is still in the plan, which is one more quiet argument for rolling eligible former-employer plans into an IRA when it makes sense. Each spouse can give up to the full $111,000 from their own IRA, so a couple’s combined ceiling is $222,000.
Taking more than the minimum: when the floor is not the plan
Here’s where “just take the RMD” falls apart as a complete strategy. The RMD is a floor, and there are three situations where deliberately taking more is the mathematically correct move.
1. The bracket-leveling year
If you’re in a year with unusually low income — a sabbatical, a year before a big bonus, a year when a pension starts or stops — the RMD is the only forced income on the table. If you expect your 2027 or 2028 bracket to be higher than today’s, taking extra now, while you’re still in the lower rate, can be cheaper than being forced to take it later. I run this math every year in my own accounts: compare the marginal tax on an extra $20,000 today against the marginal tax on that same $20,000 in the year you’d otherwise be forced out. If the gap is meaningful, the early withdrawal wins — and there’s a second-order benefit nobody expects. The RMD is a percentage of the prior year-end balance, so every dollar you withdraw early never enters next year’s division. “Taking more now” mechanically shrinks the future minimums, in the same direction as the divisor table, just faster.
2. The Social Security interaction nobody runs
Most RMD explainers stop at income tax. They ignore that every dollar of RMD also feeds the separate Social Security taxability calculation, which uses “combined income” — your AGI, plus tax-exempt interest, plus half your benefits — against thresholds that have not been indexed for inflation since the 1980s: $25,000 and $34,000 for single filers, $32,000 and $44,000 for joint filers. Above the lower number, up to 50% of your benefits become taxable; above the higher number, up to 85%.
This is where the QCD’s second benefit shows up. A $15,000 QCD doesn’t just save 22% on $15,000 of IRA income — it also keeps $15,000 out of the combined-income calculation, which can be the difference between zero and 50% of a six-figure benefit stream getting taxed. I’ve priced this out on a couple in my analysis where the RMD alone pushed combined income over the $44,000 joint threshold; the QCD brought them back under it, and the total savings across both effects was roughly double what the plain income-tax math suggested.
3. The pre-RMD window for the not-yet-73
If you’re 70 through 72 in 2026, you have no RMD yet — the last free window before the floor appears. If your 2026-2027 tax situation is light (spouse has died, a pension ends, a windfall was reinvested), taking extra now and converting some of it to a Roth IRA, while your marginal rate is still low, locks in a chunk of future withdrawals as tax-free, before the RMDs start forcing your hand at a higher balance and a higher bracket. The conversion is fully taxable in the year you do it, which is exactly why you only want it in years where the extra income lands in a bracket you’re okay with. And it’s the one RMD-adjacent move that actually reduces your future RMDs, because Roth dollars are never subject to the divisor table.
Five ways to handle your first 2026 RMD, rated
Here’s how I rate them for a typical 73-year-old with a traditional IRA at a major custodian, a 22% bracket, and Social Security in the mix:
| Strategy | Who it fits | 2026 tax effect | Main risk | My rating |
|---|---|---|---|---|
| Take the minimum, cash it out, pay tax | Anyone who needs the cash this year | Full 22% (or your bracket) on the RMD; feeds SS combined income | Highest lifetime tax of all options; no compounding left | ⭐⭐ |
| Take the minimum as a QCD to charity (up to $111k in 2026) | 70½+ with a planned gift, any charity | Dollar-for-dollar off taxable income and off SS combined income | Only works from an IRA, and only if custodian sends check directly | ⭐⭐⭐⭐⭐ |
| Take the minimum, then convert the extra to Roth in a low-bracket year | Light-income years; heirs likely | Pays tax now at your low rate; future withdrawals tax-free | Over-converting in a high year locks in a high rate forever | ⭐⭐⭐⭐ |
| Take 2x the minimum to level brackets | Year with unusually low income; expect higher later | Pays lower rate now; shrinks future RMDs mechanically | Cash drag if the extra isn’t invested; depletes principal faster | ⭐⭐⭐ |
| Delay first RMD to April 1, 2027 with no plan | Almost nobody, by default | Two RMDs land on one 2027 return | Bracket spike in 2027; SS threshold breach; pure inertia | ⭐ |
The star ratings are my judgment from running the numbers, not a universal answer. But the pattern is consistent: the default (first row) is the most expensive option in the table, and the two top-rated options are the ones almost no one reaches for without being shown the math.
The penalty most people still describe with the old number
Ask ten financial professionals what happens if you miss your RMD and you’ll hear “50%.” That was the old law. SECURE 2.0 cut the excise tax on an RMD shortfall to 25% for distributions in 2023 and later, and added a correction window that drops it to 10% if you take the missed amount before the window closes — generally the end of the second year after the year of the missed RMD. A missed 2025 RMD can still be corrected by December 31, 2027 at the reduced rate; a missed 2026 RMD’s window closes December 31, 2028.
There’s also a waiver path: file IRS Form 5329 with a statement of reasonable cause — a custodian error, an advisor’s mistake, illness, a family disruption — and the IRS can reduce the penalty to zero. It’s not automatic, but it’s granted in clean, well-documented cases. Two things I’d do either way: take the corrective distribution immediately rather than waiting for the window to close, and keep the paper trail (the 5329 filing, the explanation, the date the money moved), because that’s what the waiver request is built on. One more detail that matters for the 2026 cohort: the IRS generally has three years after you file the return for the year of the missed RMD to assess the excise tax — six years if you never filed the 5329 at all. “Nobody told me” is not a defense, and the statute isn’t as forgiving as some blogs imply.
Six mistakes I see every RMD season
Working through the 1953-cohort math year after year, the same failures keep showing up, and almost none of them are about not knowing the formula.
- Treating the RMD as a ceiling. Some retirees take the RMD and stop, because they “don’t need more.” But if spending needs $30,000 and the RMD is $18,800, they’re taking the other $11,200 from the account anyway — at the same tax cost, with none of the planning. The RMD should be the floor of a distribution plan, not the entire plan.
- Using this year’s balance instead of last year’s. The formula uses December 31 of the prior year. Custodians show the current balance on every screen; when the two disagree, the prior year-end number wins.
- Forgetting the inherited IRA in the house. An inherited IRA has RMD rules of its own, computed on a different table, and it’s a separate obligation — the one most often missed because it sits at a different brokerage and the custodian’s reminder only covers the owner’s accounts.
- Letting the custodian “handle it” without confirming. Most major custodians will calculate and sometimes automatically take your RMD, which is fine — until the automatic amount is wrong, you moved the account mid-year, or the QCD you asked for got processed as a regular distribution. “I told them to send it to the charity” is not a completed transaction; the check from the custodian to the charity is. Confirm the distribution type on the year-end statement.
- Ignoring the Social Security interaction. The RMD is the one retirement income you can’t avoid taking, so it’s the first thing to push combined income over the lines where up to 85% of benefits become taxable. The QCD is the cleanest fix; the bracket-leveling withdrawal is the second-best. Neither shows up in a generic withdrawal plan unless someone runs the Social Security worksheet.
- Waiting until December. By then the market has already decided your balance and QCD paperwork in a busy custodian queue takes longer than it should. For the 2026 cohort, I’d finish the worksheet by Q3: confirm the December 31, 2025 balance, confirm your birth-year start age, decide QCD versus cash — and if you’re taking the April 1, 2027 delay, write down the reason, because the double-distribution year deserves a deliberate choice, not a default.
Frequently Asked Questions
When exactly is my first RMD due if I turn 73 in 2026?
December 31, 2026 — or, for your first RMD only, you can delay it until April 1, 2027, in which case you owe both the 2026 and 2027 RMDs on one 2027 return. The rule is by birth year: 1951–1959 start at 73, 1960 and later at 75. If your money is in a current employer’s 401(k) and you’re still working, that plan’s RMD can wait until the year after you retire (unless you own more than 5%), but IRAs have no such delay.
How do I calculate the RMD without a calculator service?
Take your account balance as of December 31 of the prior year and divide by the divisor for your age from the IRS Uniform Lifetime Table: 26.5 at 73, 25.5 at 74, 24.6 at 75, 20.2 at 80. A $500,000 balance at age 75 gives a $20,325 RMD. If you have several IRAs, compute each one’s RMD separately but may take the total from one. If your spouse is your sole beneficiary and at least 10 years younger, the Joint and Last Survivor Table applies instead.
Can a QCD pay my entire RMD and owe zero tax on it?
Yes — if you’re 70½ or older, the money moves straight from the IRA to a qualified charity, and the amount is within the 2026 limit of $111,000 per person. If your RMD is $27,900 and you QCD $27,900, the entire distribution is excluded from income and doesn’t feed the Social Security combined-income calculation. QCDs only work from IRAs, and most donor-advised funds and private foundations don’t qualify as recipients — a common point of failure.
What happens if I miss my RMD?
The shortfall is subject to a 25% excise tax, not the old 50%. If you take the missed distribution within the correction window — generally by the end of the second year after the missed year — it drops to 10%. You can also file Form 5329 requesting a waiver with a reasonable-cause explanation, and the IRS grants waivers in documented cases like custodian or advisor errors.
Does taking my RMD early in the year lower next year’s RMD?
Taking more than the minimum lowers next year’s RMD, because next year’s amount is computed on the prior year-end balance — a smaller ending balance means a smaller number in the division. Taking the RMD itself early doesn’t change this year’s amount (it’s fixed by last year’s balance), but the timing of your extra withdrawals does matter for the next year’s floor. The RMD is a percentage of whatever you leave behind, every single year.
This is general information, not financial advice, and tax rules change. RMD amounts, divisors, and the 2026 limits above are based on IRS publications and 2026 inflation adjustments as of writing; confirm your specific situation — especially beneficiary tables, QCD eligibility, and correction-window deadlines — with a qualified tax professional before acting.
