Lottery Winnings Tax Calculator 2026 — Federal + State Withholding

The IRS requires 24% federal withholding on lottery winnings over $5,000. This is reported on Form W-2G. However, 24% is rarely enough for large jackpots — high earners face the 37% top marginal rate. At filing, you will owe the difference between what was withheld and your actual marginal rate. For a $1 million jackpot, withholding is $240,000 but actual federal tax could be $370,000, leaving $130,000 owed at filing. Winners should make quarterly estimated tax payments on top of withheld amounts to avoid underpayment penalties.

The lump sum (cash value) is typically 50-60% of the advertised jackpot. For a $100M jackpot: lump sum ≈ $55M, then 37% federal + 5% state ≈ $32M net. The annuity pays the full $100M over 30 years ($3.33M/year), and each payment is subject to federal + state tax — but only ~37% goes to the top bracket rather than the entire lump sum. If you assume 5% investment return on the lump sum, present value of the annuity is roughly equivalent to the lump sum before taxes — making the annuity often more valuable after tax for disciplined savers. Financial advisors generally recommend modeling both scenarios.

Nine states have no state income tax and therefore do not tax lottery winnings: Alaska, Florida, Nevada, New Hampshire (no income tax), South Dakota, Tennessee, Texas, Washington, and Wyoming. Additionally, California (unusually for a high-tax state) does not tax lottery winnings. Delaware and Pennsylvania have state income taxes but do not impose state withholding on lottery winnings (though they may be partially taxable). Always verify your state's current rules as they can change. If you win in a different state than where you live, you may owe taxes in the state where you bought the ticket AND in your home state (with credit for taxes paid).

Yes, potentially. If you buy a lottery ticket in State A but live in State B, you may owe taxes in both states. State A taxes the winnings as sourced within its borders. State B taxes you as a resident on worldwide income. Most states offer a credit for taxes paid to other states, so you generally do not pay double tax — you pay the higher of the two state rates. If you live in a no-income-tax state (TX, FL, etc.) but win a lottery in a state with income tax (NY, CA), you may owe tax to that state but not your home state.

To compare lump sum vs annuity, you need to discount future annuity payments to present value using an assumed investment return rate. If the annuity pays $100M over 30 years and you could earn 5% investing the lump sum, the NPV of the annuity stream at 5% discount rate is approximately $58-65M. The lump sum cash value (advertised separately by lotteries, typically 50-65% of jackpot) should be compared to this NPV. Generally: if the lump sum after tax exceeds the NPV of the annuity after tax, take the lump sum. A higher discount rate favors the lump sum; a lower rate favors the annuity.
