If you win $1 million and it’s your only income for the year, you can expect to pay roughly $320,000 in federal income tax on 1 million dollars for the 2026 tax year, leaving about $680,000 before state taxes. State income tax can take another $0 to $130,000 depending on where you live, so the realistic take-home on a lump-sum prize lands somewhere between $550,000 and $680,000. The IRS treats lottery, sweepstakes, and gambling winnings as ordinary income, taxed through the same brackets that apply to wages.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
The Federal Tax on a $1 Million Prize
Your prize stacks on top of any wages, investment income, or other earnings you already had that year. Subtract the 2026 standard deduction of $16,100 for a single filer and you get taxable income of $983,900 if the prize is your only income.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
The federal system is progressive. Each slice of income is taxed at its own rate; you don’t pay 37% on the whole prize. The 2026 brackets for a single filer:
- 10% up to $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% on income above $640,600
Running $983,900 through those brackets produces a federal bill of about $320,000, an effective rate of roughly 32% on the full million. If you had other income that year, more of the prize lands in the 37% bracket and the effective rate climbs.
What Gets Withheld Before You See the Money
You will not receive a check for the full amount. The payer must withhold 24% of any payout over $5,000 from a lottery or sweepstakes and send it to the IRS.3Internal Revenue Service. Instructions for Forms W-2G and 5754 On a $1 million prize, that’s $240,000 gone before the money hits your account. The gross prize and the withheld amount are both reported on Form W-2G, which the payer also sends to the IRS.4Internal Revenue Service. About Form W-2G, Certain Gambling Winnings
Here’s the trap: 24% withheld against roughly 32% owed leaves an $80,000 shortfall. That gap doesn’t quietly wait until April. If you don’t pay it in during the year, the IRS charges an underpayment penalty plus interest, currently 7% per year compounded daily.5Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026
Paying the Shortfall Without Penalties
The fix is an estimated tax payment using Form 1040-ES. For 2026, the quarterly deadlines are April 15, June 15, September 15, and January 15, 2027.6Internal Revenue Service. 2026 Form 1040-ES, Estimated Tax for Individuals If you win mid-year, pay the balance by the next deadline after you collect. A single large estimated payment right after winning is fine.
To stay penalty-free, you generally need to cover the lesser of 90% of your 2026 tax or 100% of your 2025 tax.7Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty A $1 million win almost certainly pushes your adjusted gross income above $150,000, which raises the prior-year safe harbor from 100% to 110%. The simplest approach: calculate your full estimated 2026 tax, subtract the $240,000 already withheld, and send the difference to the IRS before the next quarterly deadline.
State Taxes on Lottery and Gambling Winnings
Federal is only part of the bill. Most states impose their own income tax on winnings, with top rates ranging from under 3% to more than 10%. Seven states levy no income tax at all, and a few others specifically exempt lottery prizes. Where you live can swing your net by $50,000 to $100,000 on a million-dollar prize. In a handful of high-tax states, combined state and local rates can top 13% once city taxes come in.
If you bought the winning ticket while traveling, the state where you won will tax the prize because the income originated there. Your home state will also tax it based on residency. Most home states offer a credit for taxes paid to the other state, so you pay the higher of the two rates rather than both stacked. You’ll file a nonresident return where you won and claim the credit on your resident return.
Lump Sum or Annuity
Most large lottery prizes let you choose between a lump-sum check and an annuity that spreads payments over 20 to 30 years. The tax bill on each is very different.
A lump sum delivers the full cash value in one year, and every dollar is taxable that year. Most of a $1 million prize lands in the 35% and 37% brackets. You control the money now, but the tax hit is concentrated.
An annuity splits the prize into annual installments and each payment is taxable only when received. A $1 million prize paid over 20 years produces about $50,000 a year before taxes. A single filer with no other income at $50,000 stays in the 22% bracket or lower, a meaningful drop from the marginal rates a lump sum triggers.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The trade-off is a payment schedule you can’t undo and exposure to whatever future tax rates Congress sets.
Sharing the Prize Triggers Gift Tax Rules
Splitting winnings with family or friends brings in a separate set of rules. For 2026, you can give up to $19,000 per person per year without filing a gift tax return or touching your lifetime exemption.8Internal Revenue Service. What’s New – Estate and Gift Tax A married couple can give $38,000 per recipient by splitting the gift.
Anything above $19,000 to a single recipient requires filing Form 709.9Internal Revenue Service. Instructions for Form 709 Filing doesn’t mean you owe gift tax. The excess counts against your lifetime gift and estate exemption, which is $15,000,000 for 2026.8Internal Revenue Service. What’s New – Estate and Gift Tax A winner who gives away $200,000 owes no gift tax but uses a slice of that lifetime exemption and has to report it.
The costly mistake is thinking that handing half the winnings to a sibling cuts your income tax in half. It doesn’t. The IRS treats the winner as the taxpayer on the full prize, and gift rules apply to whatever moves after that. You pay income tax on the full $1 million either way.
Deducting Gambling Losses
Losing tickets and other gambling losses can offset winnings on your federal return, but only if you itemize on Schedule A instead of taking the standard deduction. Losses can’t exceed winnings for the year.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Starting with the 2026 tax year, the One Big Beautiful Bill Act limits the deduction to 90% of gambling losses, down from 100%. If you won $1 million and lost $100,000, you used to deduct the full $100,000; now the deductible amount is $90,000, leaving an extra $10,000 exposed to tax. Legal fees and accountant costs tied to the prize are not deductible — those fall under miscellaneous itemized deductions, suspended since 2018.10Internal Revenue Service. Publication 529, Miscellaneous Deductions
The Bottom Line on a $1 Million Win
For a single filer with no other income taking a $1 million lump sum in 2026, the math looks roughly like this:
- Gross prize: $1,000,000
- Federal withholding at 24%: −$240,000
- Check you receive: $760,000
- Estimated total federal tax: about $320,000
- Additional federal tax owed at filing: about $80,000
- State tax: $0 to $130,000 or more
- Realistic take-home: roughly $550,000 to $680,000
The range tightens or widens with your state, your other income, and any deductible losses. The winner who keeps the most is the one who sends an estimated tax payment within weeks of collecting, keeps clean records of any losses, and talks to a tax professional before making gifts or large purchases.
