Worked example
A $100 million jackpot with a 46% cash option, single filer with $60,000 of other income and a 5% state tax. The cash option is $46 million. Federal tax is $16,987,180 (top rate 37%) and state tax $2,300,000, leaving $26,712,820. The lottery withholds $11,040,000 (24%), so about $5.9 million more is due at tax time. The 30-year annuity starts at $1,505,144 a year and totals $58,984,593 after tax.
If you win big
- Sign the ticket and keep it somewhere safe.

Frequently asked questions
How much tax do you pay on lottery winnings?
Lottery winnings are ordinary income. A jackpot is taxed mostly at the top federal rate of 37%, plus state tax of up to about 11% depending on the state. On a $46 million cash prize, federal tax is about $17 million.
How much does the lottery withhold?
Lotteries withhold 24% federal tax on prizes over $5,000 (and many states withhold their own tax). For large prizes that is not enough: the rest is due when you file.
Should I take the lump sum or the annuity?
The lump sum gives you control and investment growth now; the annuity spreads the tax over 30 years and protects you from spending too fast. The annuity pays more in total, but the lump sum can grow if invested well.
How does the jackpot annuity work?
For Powerball and Mega Millions, the advertised jackpot is paid as one payment now and 29 yearly payments, each 5% larger than the last. The cash option is the money the lottery has to fund those payments, often 45% to 50% of the jackpot.
Which states do not tax lottery winnings?
States with no income tax on wages or winnings, such as Florida, Texas, Tennessee, Washington, South Dakota, Wyoming and New Hampshire, and California, which exempts its own state lottery prizes. Some cities, like New York City, add their own tax.
Do I pay tax on small lottery wins?
Yes. All winnings are taxable income, even when no tax is withheld or no form is issued. Report them on your return.
Can lottery losses offset winnings?
Only if you itemize, and from 2026 only 90% of losses count, up to your winnings. Ticket costs are gambling losses.
What if I share a ticket with others?
Each winner reports their share. Use Form 5754 at claim time so the lottery issues a W-2G to each person; otherwise one person may be taxed on the whole prize.
Can I give some of my winnings away tax-free?
Gifts up to $19,000 per person a year are not reported; larger gifts use your $15 million lifetime exemption. See the Gift Tax Calculator.
Does this include state tax exactly?
It uses the flat rate you enter. Most states with a progressive tax reach their top rate on large prizes, so use your state's top rate for a jackpot.
