Lottery Tax Calculator

Last updated: October 4, 2026 ET

Use this free lottery calculator to estimate Powerball, Mega Millions, and other payouts after federal, state, and local tax assumptions. Choose a game, adjust the planning rates, and compare cash with annuity.

Lottery taxes: the quick answer

Federal withholding is not the same as your final lottery tax bill. When U.S. lottery winnings minus the wager exceed $5,000, the payer generally withholds 24% of the proceeds for federal income tax before payment. A large jackpot can still put part of your taxable income in the 37% top federal bracket, so the final amount due is settled when you file.

24% withheld

Usually a prepayment on qualifying winnings, not the final rate.

Up to 37% federal

Large prizes can push taxable income into the top marginal bracket.

State and local tax

The claim location, residence, and city can materially change take-home value.

The calculator starts with the advertised jackpot, then shows either the cash option or annuity payment before and after the federal, state, and local assumptions you choose. See the IRS guidance on gambling income and withholding for federal rules.

1. Choose the lottery game and advertised jackpot.
2. Choose a federal tax-rate assumption.
3. Choose where you live and add city tax when it applies.
4. Select lump sum for the cash option, or annuity for annual payment estimates.
5. Use the result as planning context, then talk with a tax professional before any real claim.

How this lottery tax calculator works

This is a transparent planning estimate, not a tax return. It applies the federal, state, and local rates selected in the calculator to either the current cash option or an estimated annuity payment. It does not calculate progressive brackets, deductions, credits, other income, or cross-state tax credits.

Formula and assumptions

Cash estimate: estimated take-home = cash option × (1 − federal rate − state rate − local rate).

Custom jackpot: estimated cash option = custom advertised jackpot × the selected game's current cash-option-to-annuity ratio. That ratio changes with the official cash value, so a custom result is an extrapolation rather than a quoted lottery payout.

Annuity estimate: the calculator uses the selected game's payment count and annual increase where available. Powerball and Mega Millions commonly use 30 payments that increase 5% each year; other lotteries can use different schedules.

The 24% regular federal withholding discussed below generally applies when lottery winnings minus the wager exceed $5,000. It is a prepayment toward federal tax and is not added on top of the selected federal rate in the calculator.

Powerball & Mega Millions tax calculator by state

For multi-state jackpots, the same advertised prize can lead to different take-home estimates depending on the selected state tax input. Choose Powerball or Mega Millions in the calculator, then use the state selector to compare federal tax, state income tax, optional city/local tax, cash option, and annuity estimates.

State-specific lottery games are handled differently when the game record identifies a dedicated claim state: the calculator uses that state context instead of asking you to pick a state manually.

Lottery tax rates by state

These are the state planning assumptions available in the calculator for tax year 2026. Positive rates use the current top state individual income-tax rate as a simple proxy; 0% means no state tax is included in this estimate. Neither label guarantees the treatment of a particular ticket or winner.

Last policy review: September 16, 2026. A state omitted from this table has no supported calculator assumption; omission does not mean its rate is 0%.

Worked lottery tax examples

These fixed examples explain the arithmetic without pretending to quote a current jackpot or a personal tax return.

Example: $1 million cash prize

At a selected 37% federal planning rate and 0% state and local rates, the estimate is $1,000,000 × (1 − 0.37) = $630,000. Federal withholding may initially be 24%, or $240,000, but withholding is not necessarily the final federal liability.

Example: advertised jackpot converted to cash

Assume a $100 million advertised jackpot and a 45% cash-value ratio. The estimated cash option is $45 million. At a selected 37% federal rate with no state or local rate, the simplified take-home estimate is $28.35 million.

Example: state-rate comparison

Using that same $45 million cash option, adding a 10% state planning rate changes the estimate from $28.35 million to $23.85 million. A real result can differ because states may use thresholds, exemptions, credits, withholding rules, or local taxes that this simplified comparison does not model.

Purchase state, claim state, and residence

One state selector cannot resolve every cross-state tax question. The state where the ticket was purchased, the jurisdiction paying the prize, and the winner's residence can all matter. A resident may also receive a credit for tax paid to another state, depending on the states and the claim.

Use the selected state as a comparison assumption only. Before claiming a substantial prize, confirm the rules with the paying lottery, the relevant state tax agencies, and a qualified tax professional familiar with multistate gambling income.

Lottery lump sum vs. annuity after taxes

Cash is not automatically the better payout. The lump sum starts with less money than the advertised jackpot, but it can finish ahead if the after-tax amount you invest earns enough to overtake the annuity schedule. That required return is the useful comparison: if it is higher than a return you could realistically sustain after fees and taxes, the annuity may be stronger.

The answer changes by game. Powerball and Mega Millions commonly use 30 payments, beginning immediately and increasing 5% each year; some state lotteries use level payments or different timing. Taxes, inflation, the amount invested, and the years compared can all move the crossover point.

Compare lump sum and annuity payouts to see the projected winner, break-even return, crossover year, and inflation-adjusted values for a lottery.
