The IRS treats lottery winnings as ordinary taxable income, just like the wages from a regular day job. The moment you win a large jackpot, the federal government steps in to take a cut. They do not view this money as a tax-free gift.
Before a winner ever touches the prize, the paying agency automatically deducts a flat 24% for federal taxes on any amount over $5,000. That sounds simple enough. It isn’t. The 24% figure is essentially a down payment to the IRS. It rarely covers the final tax liability for a major win. Depending on the size of the payout, the real tax bill can wipe out nearly 40% of the total cash.
How Progressive Income Brackets Work
The United States uses a progressive tax system. Your prize money stacks directly on top of your standard yearly income. The total combined sum dictates your specific tax brackets for the year.
For the 2025 tax year, which citizens file in 2026, the highest federal marginal tax rate sits at 37%. This top rate applies to individuals earning over $626,350. Any multi-million dollar jackpot immediately pushes the winner into this uppermost tier.
Older winners frequently worry that a sudden windfall will wreck their retirement benefits. It does not. The IRS does not consider prize money to be earned income. This means a jackpot will not affect Social Security payments, as noted in a TaxAct tax overview. It also means you cannot use the winnings to qualify for earned income-based tax credits.
When you finally claim the prize, the lottery agency issues an IRS Form W-2G to report the income. You can deduct the cost of losing tickets to offset your tax burden. But you can only write off those losses up to the amount you won, according to H&R Block documentation. You cannot claim losses that exceed your actual winnings.
The Withholding Gap Trap
The biggest financial hazard for a new millionaire is the space between the 24% automatic withholding and the 37% top tax bracket. That creates a highly dangerous 13% gap.
The lottery agency takes 24% off the top. The winner gets the rest in cash. If they spend, invest, or give away all that cash without setting aside liquid funds for the remaining 13% liability, they will face severe tax debts the following April.
Real-World Tax Math
Consider a single filer earning $45,000 a year who wins $100,000. Their total taxable income instantly becomes $145,000. The lottery agency withholds $24,000 immediately.
Because the tax system is progressive, the winner does not actually pay 24% on the whole amount. They pay 10%, 12%, and 22% on the lower tiers of their income. The 24% rate only hits the income exceeding limits of the $103,350 threshold. In this scenario, the winner often receives a small tax refund in the spring.
Now scale that math up. Imagine a $930 million payout.
The 24% federal withholding instantly removes $232.2 million from the jackpot. Because nearly all of that remaining income falls into the top 37% bracket, the winner owes an additional 13%. That equals an estimated extra tax of roughly $111.9 million due at tax time.
State Taxes and Payout Structures
Federal rules are just one piece of the puzzle. State governments want their share too. Location completely alters the final net payout.
Winners living in Florida, Texas, Washington, and New Hampshire pay zero state income tax on their prizes. Conversely, winners in New York face a state tax of up to 10.9%, plus an extra 3.876% city levy. A winner in Manhattan takes home millions less than a winner in Miami for the exact same ticket.
Winners also face an immediate choice: take the lump sum or the annuity.
- Lump Sum: This option provides a smaller total pool of money upfront. It subjects the entire amount to the 37% rate in a single tax year.
- Annuity: This option spreads the payout over 30 years. You receive an immediate partial payment, followed by 29 annual payments that increase by 5% every year.
Choosing the annuity artificially lowers your annual taxable income. By splitting the money up, portions of your yearly payout stay in the 10%, 12%, and 22% tax brackets, rather than subjecting the entire jackpot to the 37% rate on day one.
The Verdict
For anyone claiming a multi-million dollar jackpot, the annuity option is the mathematically superior choice for tax mitigation. It structurally lowers your annual tax liability by keeping a fraction of the money out of the 37% bracket each year. If you insist on taking the immediate cash lump sum, you must immediately isolate at least 15% of your net payout into a high-yield, untouchable account. The IRS will collect the 13% difference in April, and failing to prepare for that bill is the primary reason so many lottery winners go bankrupt.
