Lottery Tax Calculator: What You Actually Keep

Enter the advertised jackpot, choose lump sum or annuity, and pick your state. The calculator applies the actual 2026 federal brackets for a single filer with no other income, then the approximate top state rate. Every output is an estimate; a real winner's return has deductions, other income, and a filing status that move the numbers.

Federal law requires the lottery to withhold a flat 24% of any prize over $5,000 and report the win on Form W-2G. That 24% is a statutory withholding rate, not your tax rate. Winnings are ordinary income stacked on top of everything else you earned that year.

For 2026, the 37% bracket starts at $640,600 of taxable income for single filers and $768,700 for married couples filing jointly. A $50 million cash prize blows through every lower bracket in the first 1.3% of the money. Effectively the whole jackpot is taxed at 37%, while only 24% was collected.

Where you live when you win matters more than where you bought the ticket. New York takes up to 10.9% (plus New York City's local tax for city residents). New Jersey and the District of Columbia run 10.75% at the top. At the other end, the no-income-tax states take nothing, and California, despite a 13.3% top California income tax rate, specifically exempts California Lottery winnings by statute.

Delaware is the trap state: it withholds nothing when you claim, which reads like an exemption, but the winnings are still subject to Delaware income tax at rates up to 6.6% on your return. Zero withholding and zero tax are not the same thing.

The advertised jackpot is the total of 30 graduated annuity payments. The lump sum is the present cash value of that stream, roughly 45 to 52% of the advertised number depending on interest rates. Take the lump sum and the entire cash value is taxed in one year. Take the annuity and each payment is taxed in the year received, at whatever rates exist then.

On a nine-figure jackpot the annuity does not rescue you from the top bracket; each payment is still millions. Where the annuity genuinely helps is mid-size prizes, where spreading, say, a $3 million win over 30 years keeps each payment out of the 37% bracket entirely. The honest framing: the lump sum is a bet that your after-tax investment returns beat the lottery's built-in escalator plus the risk of future rate hikes. Once the money is invested, the growth is governed by capital gains rules, which top out well below ordinary rates and are the reason most large winners' second decade is taxed more gently than their first year.

The IRS expects tax as income arrives, not just in April. Because only 24% was withheld on a prize that owes 37%, a jackpot year is an automatic underpayment problem. The escape hatch is the safe harbor: no penalty if your withholding plus estimates cover 100% of last year's total tax, or 110% if your prior-year AGI was over $150,000.

That safe harbor is winner-friendly math. Say last year's total tax was $40,000. Pay in $44,000 through the year (110%) and the remaining millions of jackpot tax are penalty-free until the April filing deadline. Park the reserved tax money in Treasury bills and the interest is yours instead of the government's. Miss the safe harbor and the underpayment penalty runs like interest at the IRS rate, quarter by quarter. The mechanics, deadlines, and penalty math are covered in the estimated tax penalty guide.

Losing tickets have always been a limited consolation: gambling losses are deductible only if you itemize, and only up to the amount of your winnings. No carryover, no netting against wages, and no deduction at all if you take the standard deduction.

Starting with the 2026 tax year, the One Big Beautiful Bill Act tightened this further: only 90% of wagering losses are deductible. Win $100,000 and lose $100,000 in the same year, and you now report $100,000 of income against a $90,000 deduction, paying tax on $10,000 you never actually kept. Repeal bills are pending, but as of this writing the 90% limit is the law for 2026.

Casino, poker, and sports betting winnings follow their own W-2G reporting and withholding thresholds, covered in our gambling winnings tax guide.

1. Spending the withholding gap.

The single most common windfall mistake: treating the post-withholding wire as spendable. On a large lump sum, roughly 13% of the cash value is federal tax that has not been collected yet, plus the state's share in most states. Reserve it on day one.

2. Casual sharing that becomes a gift tax problem.

Handing family members big checks after claiming solo is a gift, and gifts beyond the annual exclusion (around $19,000 per recipient) eat into your lifetime exemption and require a gift tax return. If a group genuinely shared the ticket, document it with Form 5754 before claiming so everyone gets their own W-2G instead.

3. Forgetting that prizes are not the only windfall taxed this way.

Raffle wins, game show prizes, fantasy sports payouts, and crowdfunding proceeds can all be ordinary income with little or no withholding. The same reserve-and-estimate playbook applies. If money arrived through a GoFundMe or similar campaign, the rules are different again, and covered in our GoFundMe taxes guide.

4. Making irreversible decisions in week one.

The claim deadline is months away in every state. Winners who assemble a CPA, an attorney, and a fee-only advisor before claiming consistently keep more than winners who show up at the lottery office the next morning. Anonymity rules, trust claiming, and the lump-sum decision all get decided once, permanently, at the window.
