The government takes a large share of lottery winnings in layers. On any prize above $5,000, the federal government withholds 24 percent before you see a check, and the final federal bill often climbs to 37 percent once you file. State income tax can add anywhere from zero to about 10.9 percent on top of that. In practical terms, how much the government takes from lottery winnings usually works out to somewhere between roughly a third and half of a large prize, and considerably more of the advertised jackpot if you choose the lump sum.
The 24 Percent Taken Before You See a Check
Federal law requires the lottery to withhold 24 percent of any prize over $5,000 and send it straight to the IRS.1Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source The lottery agency acts as a collection agent, deducting the amount before it hands over your winnings. That 24 percent is not the final tax bill. It is a prepayment, the same way an employer withholds from a paycheck.
You also have to give the lottery office your Social Security number when you claim the prize. If you don’t, backup withholding kicks in, also at 24 percent, and it can apply to smaller prizes that wouldn’t otherwise trigger automatic withholding.2Internal Revenue Service.

One narrow exception raises the rate. Nonresident aliens face 30 percent withholding under a separate section of the tax code, though a treaty with the winner’s home country may lower that figure.3Office of the Law Revision Counsel. 26 USC 1441 – Withholding of Tax on Nonresident Aliens
Why You Actually Owe Up to 37 Percent
The 24 percent withheld almost never covers the full federal tax on a big prize. The United States uses a progressive system, taxing income in layers at rising rates. For 2026, the top federal rate is 37 percent, and it applies to taxable income above $640,600 for single filers and $768,700 for married couples filing jointly.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Any jackpot worth more than a few hundred thousand dollars pushes you well past that line.
That leaves a 13-point gap between what the lottery already sent to the IRS and what you actually owe on the portion of your winnings taxed at the top rate. On a $10 million prize, that gap alone can mean more than $1 million in additional tax due when you file.5Internal Revenue Service. Federal Income Tax Rates and Brackets The balance is due by the April filing deadline of the year after you win, and the IRS may also expect quarterly payments before then.
What Your State Takes
Your home state may take its own share. State income tax rates on lottery prizes run from zero to about 10.9 percent. Eight states either have no income tax at all or specifically exempt lottery winnings, so residents there pay only federal tax. Winners in the highest-tax states can lose more than a tenth of the prize to the state treasury.
Some cities and counties add local income tax, which can push the combined state-and-local rate several points higher. If you buy the ticket outside your home state, the state of purchase may withhold at its own rate, and you’ll have to sort out credits when you file at home. Two people who win the same jackpot can walk away with noticeably different amounts based on geography alone.
Lump Sum vs. Annuity Changes the Total Take
The payout choice matters before taxes even enter the picture. The advertised jackpot is the annuity value, the total paid out over roughly 30 annual installments. The lump sum cash option is typically only about 40 to 50 percent of that advertised number. A $500 million advertised jackpot might have a lump sum value of around $200 to $250 million before any withholding.
Taking the lump sum triggers the entire tax bill in one year. The whole amount counts as income for that year, and nearly all of it lands in the 37 percent bracket. After the 24 percent withholding, the additional federal amount owed at filing, and state tax on top, a lump sum winner often keeps only about half of the cash value. That works out to roughly a quarter of the original advertised jackpot.
The annuity spreads income across about 30 graduated payments over 29 years. Each installment is taxed separately at the rates in effect that year. Large installments will still hit the top bracket, but you aren’t compressing decades of income into a single tax year. The lottery continues to withhold 24 percent from each payment, and you settle the rest when you file that year’s return.
Quarterly Payments and Underpayment Penalties
The IRS often expects more than the 24 percent withheld. If your final tax bill will run well above what the lottery sent in, you may need to make quarterly estimated payments rather than wait for April. For 2026, those deadlines fall on April 15, June 15, and September 15 of 2026, and January 15, 2027.6Internal Revenue Service. Form 1040-ES, Estimated Tax for Individuals
Skip enough of those payments and the IRS adds an underpayment penalty. You can generally avoid it by paying at least 90 percent of the current year’s tax through withholding and estimates, or 100 percent of the prior year’s tax (110 percent if your adjusted gross income was above $150,000).7Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty The prior-year safe harbor is usually the easy option for a first-time winner, since last year’s income was almost certainly a fraction of this year’s windfall. A tax professional can pin down the right payment amount shortly after you claim the prize.
Sharing With Family Isn’t Free
Giving winnings to relatives or friends creates its own tax question. In 2026, you can give up to $19,000 per person per year without filing a gift tax return or owing gift tax.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Married couples can combine their exclusions to give $38,000 per recipient. Anything over that counts against your lifetime unified credit.
The lifetime exemption for 2026 is $15 million per person, up from $13.99 million in 2025. Gifts above the annual exclusion reduce that lifetime amount dollar for dollar, and once it’s used up, additional gifts are taxed at rates as high as 40 percent. Distributing millions to relatives without a plan can shrink your winnings twice: once as your income and again as a taxable gift. Structuring the gifts carefully and filing the required returns keeps that from happening.
How the Winnings Get Reported
The lottery reports your prize to you and to the IRS on Form W-2G, which shows the gross amount, the date, and the federal and state tax already withheld.8Internal Revenue Service. Form W-2G, Certain Gambling Winnings When you file your return, the winnings go on Schedule 1 of Form 1040, line 8b.9Internal Revenue Service. Schedule 1 (Form 1040) 2025 The IRS uses the W-2G to reconcile the withholding against your total liability, and any remaining balance is due on the April filing deadline. Plan for that payment early: late-payment penalties and interest run on top of the tax itself.10Internal Revenue Service. Topic No. 419, Gambling Income and Losses
