What this tool does
Estimates what a jackpot is worth after tax. The advertised prize is the 30-year annuity total; the cash option is typically around 60% of it. The lottery withholds a flat 24% federal tax on prizes over $5,000, but a big prize lands mostly in the 37% bracket — this tool computes the incremental federal tax on the prize with the real brackets, shows the shortfall beyond withholding, and adds a state estimate at your rate.
How to use the Lottery Tax Calculator
- Enter your figures in the fields above.
- Check the filing status, state and pay-frequency selections — they change the tables used.

- Change any input to compare scenarios; the result updates with the same dated tables shown on this page.
Formula
received = jackpot × cash % (lump) or jackpot ÷ 30 (annuity year); federal tax on prize = brackets(other income + received) − brackets(other income); withholding = 24% × received
- cash %
- Cash-option share of the advertised jackpot — about 60% for recent Powerball/Mega Millions draws; check your game's rules
Worked example
A $100M jackpot pays a $60M lump sum. Withholding takes $14.4M, but the estimated federal bill on the prize is about $22M at 2026 brackets, plus $3M of state tax at 5%.

Frequently asked questions
24% federal withholding on winnings over $5,000, reported on Form W-2G. It is a down payment, not the final tax — top-bracket winners owe up to 37% in total.
The lump sum is roughly 60% of the advertised jackpot but is invested (and taxed) under your control immediately. The annuity spreads income over 30 years, which can keep some payments below the top bracket, but locks in the schedule. Compare after-tax, after-investment outcomes, not the headline numbers.
Withholding is a flat 24%, while a jackpot pushes income through the brackets to 37%. On a $60M prize the effective federal rate is close to 37%, leaving roughly 13 points — millions — still due.
Most states with an income tax do, at rates from about 3% to over 10% (plus New York City tax). California and a few others exempt in-state lottery prizes. Enter your state's top rate for an estimate.
No — they are ordinary income, reported as other income on Form 1040, and do not qualify for capital-gains rates.
