Lottery tax: the 24% on your check is not what you owe

Lottery winnings are taxed as ordinary income at federal and state level. The IRS automatically withholds 24% from large prizes, but the true federal tax on million-dollar wins is the 37% top bracket - and the 13-point gap is owed at tax time, not at the lottery counter. State tax adds 0% to 14.776% depending on where you live, with 10 states charging nothing and New York City charging the most. Total tax on a US lottery jackpot typically ends up between 37% (no-state-tax state) and 52% (NYC).

This calculator is an estimate. Actual tax depends on your other income for the year, deductions, the exact lump-sum percentage your lottery offers, and whether you live in a city with local tax on top of state tax. The numbers below reflect 2025 IRS brackets and 2024-2025 state rates published by state revenue departments.

How lottery tax actually works

The IRS treats lottery winnings as ordinary income. They are not capital gains, they are not investment income, they are not earned wages - they are reported on Form 1040 line 8 (other income) via Form W-2G, which the lottery operator sends to both you and the IRS. The amount shown on the W-2G is the full gross winning, and the tax owed depends on stacking that amount on top of your other income for the year.

The federal tax is progressive: every additional dollar of income is taxed at the rate of the bracket it falls into. The brackets for 2025, for a single filer, are:

• 10% on income from $0 to $11,925
• 12% on income from $11,925 to $48,475
• 22% on income from $48,475 to $103,350
• 24% on income from $103,350 to $197,300
• 32% on income from $197,300 to $250,525
• 35% on income from $250,525 to $626,350
• 37% on income above $626,350

For a jackpot win, the great majority of the income lands in the 37% top bracket. The lower-bracket amounts apply only to the first $626,350 - a rounding error on a multi-million-dollar prize. For a $10 million lump sum, the federal tax is roughly $3.7 million; for a $1 million lump sum, the federal tax is roughly $355,000 (slightly under 37% because the lower brackets reduce it).

The 24% withholding trap

The IRS requires lottery operators to withhold 24% from any prize over $5,000. This is a flat federal withholding, like the withholding from a paycheck, and it shows up on Form W-2G. The trap is that 24% is the withholding rate, not the tax rate. On large prizes, the actual federal tax is 37%. The 13-percentage-point gap is owed at tax time.

The practical result: a winner who takes a $1 million lump sum gets a check for $760,000 after the automatic 24% withholding, but actually owes about $355,000 in federal tax. The check is $115,000 too generous. Anyone who spends the entire $760,000 will owe the IRS $115,000 they no longer have. Smart winners set aside at least 13% of their lump-sum check until April of the following year.

Lump sum versus 30-year annuity

US lotteries offer two payout options: a lump-sum cash value paid immediately, or an annuity of 30 payments over 29 years (the first paid right away, then 29 yearly payments after that). The lump sum is the cash present value of the annuity at current bond yields - typically 50% to 65% of the advertised jackpot. The annuity payments are graduated, increasing 5% each year, so the early payments are small and the final ones large.

For tax purposes, lump sum is the simpler case: the entire cash value is added to your income for the year, taxed at the top bracket, and you keep the rest. For the annuity, each year's payment is taxed in that year - which spreads the tax across decades and, in theory, could let some payments fall below the top bracket. In practice, even annuity payments on a $500M jackpot ($16.7M average per year) are firmly in the 37% top bracket, so the per-year tax rate is the same as for lump sum.

Most financial advisors recommend the lump sum for winners who plan to invest the proceeds, on the logic that you can invest the cash and earn more than 5%/year (the annuity growth rate). The lump sum is also better protected against changes in tax law: future Congresses could raise the top bracket above 37%, in which case future annuity payments would be taxed at the new higher rate. The annuity is better for winners who lack investment experience and want a guaranteed income stream that cannot be lost to bad decisions.

The state tax spread: 0% to 14.776%

State tax on lottery winnings ranges from 0% to nearly 15% depending on where you live. Ten states do not tax lottery winnings at all - nine because they have no state income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) and California and New Hampshire because they specifically exempt lottery prizes. Of these, California's exemption is the most notable: California has one of the highest income tax rates in the country but explicitly carves out lottery winnings.

The highest state tax rates on lottery winnings (2025):

The New York City case is the most punitive in the country. NYC residents pay 10.9% state tax plus 3.876% city tax on top of federal 37%, for a combined marginal rate of 51.776%. A $1 million lump sum in NYC nets about $482,000 after all tax - less than half the prize. The same win in Florida nets $632,000.

A worked example: $500 million Powerball

Consider a $500 million advertised Powerball jackpot. At a typical 60% lump-sum factor, the cash value is $300 million. For a single filer in Florida (no state tax):

• Cash value = $500M × 0.60 = $300M
• 24% federal withholding = $300M × 0.24 = $72M (deducted from check)
• Total federal tax = ~$110.5M (almost all at 37% bracket)
• Federal true-up owed at tax time = $110.5M − $72M = $38.5M
• State tax = $0 (Florida)
• Take-home = $300M − $110.5M = $189.5M (about 38% of advertised)

The same win for a NYC resident:

• Cash value = $300M
• Federal tax = $110.5M (same as above)
• NY state + NYC tax = $300M × 0.14776 = $44.3M
• Take-home = $300M − $110.5M − $44.3M = $145.2M (29% of advertised)

Cross-state and non-resident rules

Tax on lottery winnings is generally owed in the state of residence, not the state where the ticket was purchased. Buying a ticket in tax-free Florida does not avoid New York state tax if you live in New York. The federal tax is the same regardless.

However, six states (Arizona, Connecticut, Maryland, New Jersey, Ohio, and a few others) withhold state tax from non-resident winners at the source. The non-resident winner files a non-resident return in that state, pays the tax, and then claims a credit against their home-state liability. The end result is generally that you pay the higher of the two state rates. Florida and California residents who win out of state sometimes face state tax they would have avoided buying locally.

What you can and cannot do to reduce the tax

You cannot avoid federal tax on lottery winnings. You cannot avoid state tax in any state that taxes lottery winnings as ordinary income. You cannot defer it (the IRS taxes you in the year you receive the money - even claiming late does not push it to next year if it is paid this year). You cannot move to another state after winning to avoid tax if you were a resident of a taxing state on the day you claimed the prize.

What you can do, before claiming:

• Hire a CPA before you claim, not after. The day-of decisions (lump sum vs annuity, which name to put on the claim, trust structure) cannot be undone.
• Claim through a trust or LLC if state law allows anonymous claims - this can simplify estate planning and reduce exposure to lawsuits but does not change the tax.
• Itemize gambling losses up to the amount of winnings if you have documented losses (receipts, tickets, casino statements).
• Make charitable contributions in the same year for itemized deductions - large gifts can be deductible up to 60% of adjusted gross income for cash donations.
• Consider the annuity to spread the tax across 30 years, though each year still typically hits the top bracket.

The real take-home rule of thumb

For US lottery jackpots, the rule of thumb after federal-only tax (no state tax) is that you keep about 38% of the advertised jackpot - one fifth of the gross goes to the lottery cut (lump sum factor), and then 37% of what remains goes to federal tax. In a high-tax state like New York City, the rule drops to about 29% of the advertised amount. The ratio is remarkably stable across jackpot sizes from $50 million to $2 billion - the brackets become irrelevant once the income is large enough to mostly land in the top bracket.

The calculator above runs the exact math for any jackpot, payout option, state, and filing status combination. It is an estimate, not a binding tax computation. Real lottery winners spend their first month with a CPA and a financial advisor before spending anything else. For the rest of us, it is a worthwhile reminder that the headline number on a lottery ticket and the number that arrives in a bank account are two very different things.
