A $1 Million Inheritance, Settlement, or Business Sale That Lands in a Single Tax Year Can Put a $100,000 Earner in the 37% Bracket. Here’s How Advisors Spread It Across Three Returns Before the Check Clears
A seven-figure windfall hitting one tax return can hand the IRS a third of the check, but advisors have a fully legal move that must be locked in before the money becomes available to you.

A $1 million check feels like the end of money worries. Then the tax return arrives, and the IRS takes a cut at the highest rate. For a household that normally earns $100,000, a fully taxable windfall that lands in one year can push hundreds of thousands of dollars into the 37% bracket.
Advisors use an old and fully legal fix: they split the income across three tax years so each return stays in a lower bracket. In the example below, a married couple keeps roughly $88,000 more of the same $1 million. The catch is timing. The split has to be locked in before the money is available to you.
How $1 Million in One Year Reaches the 37% Bracket
Consider an example married couple filing jointly with $100,000 in wages in tax year 2026 and receives a $1,000,000 windfall that is fully taxable as ordinary income. Think of an inherited traditional IRA cashed out all at once, or a settlement for lost wages.
For 2026, the joint standard deduction is $32,200. The 37% rate starts above $768,700 of taxable income for married couples. The 32% rate starts above $403,550, and 24% starts above $211,400.
Add the windfall to wages and subtract the deduction, and taxable income hits $1,067,800. Brackets are fill lines, so only the top $299,100 faces the 37% bracket. Even so, federal tax comes to about $317,250, compared with $7,640 on wages alone. On its own, the windfall costs about $310,000, or roughly 31% of the check.
Spreading the Windfall Across Three Returns Saves About $88,000
Now recognize one-third of the money in each of 2026, 2027 and 2028. Taxable income each year lands near $401,133, just under the line where 32% begins. Every windfall dollar stops in the 24% bracket.
Federal tax runs about $81,468 a year, or $73,828 more than the wages-only baseline. Across three returns, the windfall costs about $221,500, roughly 22% of the check.
| Approach | Taxable Income per Year | Top Bracket Reached | Federal Tax on the Windfall |
|---|---|---|---|
| All in 2026 | $1,067,800 | 37% | $309,610.50 |
| Split over 2026 to 2028 | $401,133 | 24% | $221,484 |
The gap is $88,126.50, assuming 2026 brackets hold each year. Future brackets get inflation adjustments, which usually broadens them and helps the spread. State income tax adds its own layer, and that layer varies widely by state.
Three Tools Advisors Use, Matched to the Source of the Money
- Inheritance: use the 10-year window. Inherited cash and stock generally aren’t income. An inherited traditional IRA is the exception. It counts as income in respect of a decedent under 26 U.S.C. § 691(a), it’s taxed when you withdraw it, and it gets no step-up in basis under § 1014(c). Most non-spouse heirs must empty the account within 10 years under § 401(a)(9)(H), so three or more withdrawal years are available. If the original owner had already started required distributions, the heir also has to take annual minimums.
- Settlement: negotiate the payment schedule. Damages for physical injury are excluded from income under § 104(a), and emotional distress doesn’t count as physical injury. For the taxable portion, attorneys can write the agreement so payments arrive in separate tax years.
- Business sale: choose the installment method. Under § 453(c), a seller paid over time reports each year’s share of the gain as payments arrive, on Form 6252. Depreciation recapture is the exception, along with inventory and dealer property §§453(i) & 453(g) taxes it in the year of sale regardless.
Why the Split Must Be Set Before the Check Clears
The rule here is constructive receipt. Under 26 CFR 1.451-2(a), income is taxed in the year it is “credited to his account, set apart for him, or otherwise made available so that he may draw upon it at any time.”
Once a settlement promises a lump sum, or a buyer offers full cash at closing, you can’t turn the money down and call it next year’s income. The regulation spares income that is “subject to substantial limitations or restrictions,” and a binding payment schedule written into the contract creates exactly that.
Inherited IRAs are simpler. The money sits in the account until the heir takes it, so the heir controls the timing.
Medicare and Credit Risk Hide Behind One Big Year
Retirees face a second bill. Medicare’s income-related premium surcharges, known as IRMAA, look back two years. A seven-figure income year in 2026 would raise Part B and Part D premiums in 2028, and spreading the income reduces that hit too. IRMAA is one of nine quiet IRS rules that drain six figures from retirement accounts, all of them mapped in a free report here.
Spreading has its own risks. A buyer paying in installments can default, and a settlement payer can run into trouble before the last check. Advisors weigh the tax savings against getting paid in full today.
The best split depends on your ages, other income, state and Medicare timing. That’s math worth running with a qualified advisor before anyone signs.
