How This Lottery Tax Calculator Works

The calculator adds the winnings to your other income, applies the 2026 federal tax brackets after the standard deduction, and shows the extra federal tax the winnings cause. It also shows the 24% withheld when you claim the prize, the extra you may owe when you file, the state tax and what you keep.

2. Choose your filing status and enter your other taxable income.
3. Enter your state’s income tax rate on lottery winnings (0 if none).

How the Tax Is Estimated

• Net winnings: winnings − cost of the ticket
• Withholding: 24% of net winnings if they are more than $5,000
• Federal tax on winnings: tax on (other income + winnings − standard deduction) − tax on (other income − standard deduction)
• Tax due at filing: federal tax on winnings − withholding
• Take-home: net winnings − federal tax − state tax

Key Terms

• Withholding: tax taken from your winnings when you claim them.
• Form W-2G: the IRS form a lottery uses to report your winnings and the tax withheld.
• Cash option: a single lump-sum payment, smaller than the advertised annuity jackpot.
• Annuity: a series of yearly payments over many years.
• Marginal rate: the tax rate on your last dollar of income.

Worked Example

A married couple filing jointly, with $90,000 of other income, wins $20,000 in a state lottery that has no income tax.

• Withheld when they claim: 24% × $20,000 = $4,800
• Their taxable income rises from $57,800 to $77,800, all in the 12% bracket
• Extra federal tax: $2,400, so they may get about $2,400 back when they file
• Take-home: $17,600

Real-Life Examples

• $1 million, single: federal tax about $337,180, with $97,180 still owed after withholding.
• $20,000, married: withholding of $4,800 is more than the $2,400 of tax, so a refund is likely.
• $10 million cash option, married, no other income, 4.25% state tax: take-home about $5,964,750.
• Small win: $3,000 has no withholding, but it is still taxable income on your return.

Withholding vs Actual Tax

• Withholding: the 24% taken from your prize when you claim it and sent to the IRS.
• Actual tax: worked out on your return using all your income and the brackets.
• The gap: large prizes usually owe more than 24%; smaller prizes may get some back.

Lump Sum or Annuity

Big jackpots offer a cash option, paid at once, or an annuity paid over many years. The cash option is much smaller than the advertised jackpot, and taking it in one year pushes almost all of it into the 37% bracket. Annuity payments are spread out, so each year’s payment is taxed in that year, which may keep some of it in lower brackets, but you wait decades for the money. Enter the cash option, or one year’s annuity payment, to see the tax for that year.

Many winners talk to a tax adviser before choosing. You may also need to make estimated tax payments so you do not face an underpayment penalty.

Common Mistakes to Avoid

• Assuming 24% is the final tax. Big prizes usually reach 37%.
• Using the advertised jackpot. Enter the cash option or one year’s payment.
• Forgetting state tax. It can take several percent more.
• Spending before tax time. Keep money aside for the tax you will owe.
• Not reporting small wins. All lottery winnings are taxable income.
