Introduction
Winning the lottery is exciting, but taxes take a big chunk of your prize. The IRS taxes lottery winnings as ordinary income, and most states add their own tax on top. Depending on where you live and how you choose to get paid, you could lose 30% to 50% of your jackpot to taxes.
This lottery tax calculator helps you figure out how much you actually keep after federal and state taxes. Enter your jackpot amount, pick your state, and choose between a lump sum or annuity payout. The calculator uses 2025 federal tax brackets to estimate your total tax bill, your effective tax rate, and your net take-home amount. It also shows you a side-by-side comparison of lump sum versus annuity so you can see which option puts more money in your pocket.
How to Use Our Lottery Tax Calculator
Enter your prize details and tax info below to find out how much you keep after federal and state taxes. The calculator shows your net take-home pay, a full tax breakdown, and a side-by-side look at lump sum versus annuity payouts.
Advertised Jackpot Amount: Type in the total prize amount before any taxes or deductions. This is the big number you see on the news or lottery website.
Lottery Preset: Pick Powerball or Mega Millions to auto-fill the cash value and annuity length. Choose "Custom" if you want to set those numbers yourself.
U.S. State / Territory: Select the state where you will claim your prize. Each state has a different state tax rate, and some states charge no tax at all.
Federal Filing Status: Choose how you file your federal taxes — Single, Married Filing Jointly, Married Filing Separately, or Head of Household. This affects which tax brackets apply to your winnings.
Payout Method: Pick "Lump Sum" to get one big payment now, or pick "Annuity" to spread the prize over many years. The calculator will show results for the option you choose and compare both side by side.
Lump Sum Cash Value: If you chose lump sum, enter the cash value as a percent of the jackpot. Most big lotteries pay about 60% of the advertised prize as a lump sum.
Number of Annual Payments: If you chose annuity, enter how many years the payments will last. For example, Powerball and Mega Millions pay out over 30 years. You can also use our annuity calculator to explore different payout scenarios.
Once all fields are filled in, click "Calculate My Taxes" to see your results. You will get a detailed tax summary, a visual tax breakdown bar, a lump sum vs. annuity comparison table, a step-by-step solution, and a year-by-year annuity schedule if you selected annuity.
How Lottery Winnings Are Taxed in the United States
When you win the lottery, the prize money is not all yours to keep. The IRS treats lottery winnings as ordinary income, which means you owe federal taxes on every dollar you win. Most states also take a cut. Depending on where you live and how much you win, you could lose more than 40% of your prize to taxes.
Federal Tax on Lottery Winnings
The government withholds 24% of your winnings right away. But that is usually not enough to cover your full tax bill. Lottery jackpots are large enough to push winners into the top federal tax bracket of 37%. This means you will likely owe extra money when you file your tax return. The IRS uses a progressive tax system, so different portions of your winnings are taxed at different rates — from 10% up to 37%.
State Tax on Lottery Winnings
Most states tax lottery winnings too. State tax rates range from 0% to over 10%, depending on where you live. Some states like Florida, Texas, and Wyoming have no state income tax at all. California does not tax lottery winnings either. On the other hand, states like New York and New Jersey have some of the highest state tax rates on prize money.
Lump Sum vs. Annuity Payout
Lottery winners usually get to pick how they receive their money. With a lump sum, you get a single payment right away — but it is less than the full jackpot amount, typically around 60% of the advertised prize. With an annuity, the lottery pays you the full jackpot split into equal payments over many years, usually 30. Each option is taxed differently. The lump sum gives you less money upfront but all at once. The annuity spreads your income out, but you pay taxes on each payment every year.
Why Your Filing Status Matters
Your federal tax bill depends on your filing status. Whether you file as single, married filing jointly, married filing separately, or head of household changes the income thresholds for each tax bracket. This affects how much of your winnings falls into the top bracket and how much total tax you owe.
