How Federal Lottery Withholding Works
Under IRS rules, lottery authorities are required to withhold 24% of any prize over $5,000 before issuing payment to the winner. This mandatory withholding is not optional — you cannot choose to receive the full amount and pay later. The lottery authority remits the withheld funds directly to the IRS on your behalf.
Along with your prize payment, you will receive IRS Form W-2G (Certain Gambling Winnings). This form documents the gross prize amount and the amount withheld. Both you and the IRS receive a copy. The W-2G must be included when you file your federal tax return for the year of the win.
Prizes of $600 or more may require a W-2G depending on the odds of the game. For lottery games (where odds are generally worse than 300:1), the threshold that triggers withholding is prizes over $5,000. Prizes between $600 and $5,000 are still taxable income and must be reported on your return even without a W-2G.
2026 Federal Tax Brackets for Lottery Winnings
Lottery winnings are treated as ordinary income by the IRS and are taxed at the same progressive rates as wages or business income. In 2026, the federal income tax brackets for a single filer are:
| Tax Rate | Taxable Income Range (Single Filer) |
|---|---|
| 10% | $0 – $11,925 |
| 12% | $11,926 – $48,475 |
| 22% | $48,476 – $103,350 |
| 24% | $103,351 – $197,300 |
| 32% | $197,301 – $250,525 |
| 35% | $250,526 – $626,350 |
| 37% | $626,351 and above |
Because the U.S. uses a marginal (progressive) tax system, you do not pay the top rate on every dollar — only on the dollars above each threshold. However, for jackpot-level prizes, the vast majority of the winnings land in the top 37% bracket. Practically speaking, on a $10M prize, the effective federal rate is very close to 37%.
The Gap Between Withholding and Your Final Tax Bill
This is the detail that surprises most lottery winners: the 24% withheld at the source is not your total federal tax obligation. It is a prepayment — a minimum withholding required by law. For large prizes, your actual liability is 37% (or close to it), leaving a gap of approximately 13 percentage points that you owe at tax filing.
Winners who spend their entire post-withholding payment without reserving funds for the April tax bill find themselves in serious financial trouble. Responsible prize management requires setting aside at least 13% of the gross prize into a dedicated account immediately, earmarked exclusively for the additional federal tax due.
Federal Tax by Prize Amount — 2026
| Prize Amount | 24% Withheld | 37% Total Federal Tax | Balance Owed at Filing |
|---|---|---|---|
| $10,000 | $2,400 | $3,700 | $1,300 |
| $100,000 | $24,000 | $37,000 | $13,000 |
| $1,000,000 | $240,000 | $370,000 | $130,000 |
| $10,000,000 | $2,400,000 | $3,700,000 | $1,300,000 |
| $100,000,000 | $24,000,000 | $37,000,000 | $13,000,000 |
Note: These figures show the federal tax liability only, applied to the full lump sum prize. The effective federal rate on smaller prizes may be lower due to marginal brackets. State income taxes are additional. Use the LotteryCalc tax calculator for an exact breakdown including your specific state.
Non-Resident Alien Federal Tax Rate
For lottery winners who are non-resident aliens (foreign nationals without U.S. permanent residency), the rules are different. The IRS applies a flat 30% withholding rate to U.S.-source gambling income, including lottery prizes.
Unlike U.S. citizens and resident aliens who face a 24% withholding followed by a potential 37% final liability, non-resident aliens typically have their full tax obligation satisfied by the 30% withholding — there is generally no progressive tax calculation applied, and no additional filing requirement for this income unless required by a tax treaty.
However, the U.S. has tax treaties with many countries that can reduce or eliminate the 30% withholding rate. Winners from treaty countries should consult a tax professional to determine the applicable treaty rate and whether reduced withholding can be claimed at the time of payment using IRS Form W-8BEN.
Deductions That Can Reduce Your Lottery Tax Bill
While lottery winnings are fully taxable, several legitimate deductions can reduce your net federal tax liability:
Charitable Contributions
If you donate a portion of your winnings to qualified charitable organizations, those donations are deductible as itemized deductions on Schedule A. For cash donations, you can generally deduct up to 60% of your adjusted gross income (AGI) in a single year. For very large prizes, a donor-advised fund (DAF) allows you to make a large charitable contribution in the year of the win (taking the full deduction immediately), then distribute grants to specific charities over multiple years.
Gambling Losses
You may deduct gambling losses — including lottery ticket purchases — up to the amount of your gambling winnings. This requires itemizing deductions (you cannot take the standard deduction and also deduct gambling losses). You must also have documentation of your losses: receipts, losing tickets, or a gambling diary. On a $1,000,000 prize, if you can document $50,000 in gambling losses for the year, your taxable gambling income becomes $950,000.
Qualified Business Deductions (Advanced)
In some structures — particularly if prizes are claimed through a business entity — additional deductions related to the business's operating costs may apply. This is an advanced tax planning area requiring an attorney and CPA. General consumer lottery winnings do not typically generate business deductions.
Estimated Tax Payments After Winning
If you win a lottery prize late in the calendar year and do not have federal taxes withheld at the time of payment (for example, if you win a prize just below the $5,000 withholding threshold, or if withholding is insufficient for your total liability), you may need to make estimated quarterly tax payments to avoid an IRS underpayment penalty.
The IRS requires estimated payments if you expect to owe $1,000 or more in federal taxes not covered by withholding. Estimated payments are due in four installments: April 15, June 15, September 15, and January 15 of the following year.
For large jackpot winners, the safe-harbor rule applies: you can avoid underpayment penalties by paying either 100% of your prior year's tax liability or 110% of the prior year's tax (if your prior-year AGI exceeded $150,000). However, given the size of taxes owed on major prizes, the 90%-of-current-year method is usually more accurate and avoids penalties more efficiently. Work with your CPA to set up the correct payment schedule immediately after winning.
