The Tax Reality of Lottery Winnings
Winning the lottery is life-changing, but the amount on the check is never the amount advertised. Between federal income taxes, state income taxes, and the gap between withholding and your actual tax liability, a $100 million jackpot might net you closer to $50-60 million. Understanding how lottery taxes work before you play helps set realistic expectations — and if you ever do win, it helps you plan wisely.
Federal Taxes: The Biggest Bite
Lottery winnings are treated as ordinary income by the IRS. For prizes over $5,000, the lottery commission withholds 24% for federal taxes before you receive your check. However, withholding and your actual tax liability are two different things.
The United States uses a progressive federal income tax system. For 2025, the top bracket is 37%, which applies to income above $609,350 for single filers and $731,200 for married couples filing jointly. Any significant lottery prize will push you deep into this top bracket. That means your effective federal tax rate on a large win will be very close to 37%, not the 24% that was initially withheld.
This means you'll owe additional federal taxes when you file your return. On a $10 million prize, the difference between the 24% withheld and the roughly 37% actually owed translates to over $1.3 million due at tax time — a bill that catches many winners off guard.
State Taxes: It Depends Where You Live
State tax rates on lottery winnings vary enormously, and your state of residence determines what you owe — not the state where you bought the ticket. Here's how the four states on our platform compare:
- California (13.3%): California has the highest top state income tax rate in the country. However, California notably does not tax state lottery winnings from California-operated games. Multi-state game winnings (Powerball, Mega Millions) purchased in California are also exempt from state tax. This makes California one of the most tax-friendly states for lottery winners.
- New York (10.9%): New York imposes state tax up to 10.9% on lottery winnings. New York City residents face an additional city tax of up to 3.876%, bringing the combined state and local rate to nearly 14.8%. Yonkers residents pay a smaller surcharge of about 1.477%.
- Texas (0%): Texas has no state income tax at all, so lottery winnings face zero state taxation. Winners keep everything that's left after federal taxes.
- Florida (0%): Like Texas, Florida has no state income tax. Lottery winnings are not subject to any state-level taxation.
Withholding vs. Actual Tax Owed
One of the most misunderstood aspects of lottery taxes is the difference between withholding and your final tax bill. Withholding is an advance payment — the lottery commission sends it to the IRS and your state on your behalf. But it's calculated at flat rates (24% federal, and a flat state rate), while your actual tax is calculated using progressive brackets and accounts for your total income, deductions, and filing status.
For most large prizes, the withholding amount underestimates your true liability. You'll need to either make estimated tax payments during the year or be prepared for a significant balance due in April. A tax professional can help you set up a plan so there are no surprises.
Estimated Effective Rates by Prize Size
Here's a rough guide to combined effective tax rates for different prize sizes, assuming a single filer with no other significant income:
- $10,000 prize: Federal effective rate around 12-22%, depending on other income. State varies. You might take home $7,500-$8,500 in a no-tax state.
- $1 million prize: Federal effective rate approximately 35-36%. In New York City, combined taxes could reach 48-50%. In Texas or Florida, closer to 35-36% total.
- $100 million prize (lump sum): Federal effective rate very close to 37%. A New York City resident could lose nearly 52% to combined taxes. A Florida or Texas resident keeps roughly 63% after federal taxes alone.
These are rough estimates. Your actual tax situation depends on filing status, deductions, other income, and current tax law. For a more detailed breakdown tailored to your scenario, try our jackpot tax calculator.
Annuity vs. Lump Sum: Tax Implications
The choice between annuity and lump sum affects your taxes significantly. The lump sum is typically around 60% of the advertised jackpot, and the entire amount is taxable in the year you receive it. Annuity payments spread the income over 30 years, which could keep portions of your income in lower brackets during the early years — though for very large jackpots, you'll still hit the top bracket annually.
We cover this decision in depth in our article on annuity vs. lump sum, including factors beyond taxes like investment returns and personal circumstances.
Protecting Your Winnings
Tax planning should be one of the first things you address after a major win. Before claiming your prize, consult a tax professional and a financial advisor. Many state lotteries give winners 60 days to a full year to claim, so there's no rush. Proper planning — including setting up trusts, managing estimated payments, and understanding your state's rules — can save you from costly mistakes.
