Unlike the UK, the United States taxes gambling winnings. All winnings are considered ordinary income by the IRS and must be reported on your federal tax return — regardless of the amount, the type of gambling, or whether you received a W-2G form. This guide explains the rules clearly so you know exactly what you owe and how to minimize your tax liability legally.
This guide is for informational purposes only and does not constitute tax advice. US tax law is complex and individual situations vary. Consult a qualified tax professional for advice specific to your circumstances.
The Core Rule: All Gambling Winnings Are Taxable
The IRS treats all gambling winnings as ordinary taxable income under IRC Section 61. This includes:
- Online casino winnings (slots, table games, poker)
- Sports betting winnings (both online and retail)
- Lottery winnings
- Horse racing winnings
- Sweepstakes and prize winnings
- Fantasy sports winnings (DraftKings, FanDuel daily contests)
You must report gambling winnings on Schedule 1 (Form 1040), Line 8b: "Other Income." There is no minimum threshold below which winnings are exempt — every dollar is technically reportable.
Federal Tax Withholding Rates
For winnings above certain thresholds, the payer (casino or sportsbook) is required to withhold federal income tax before paying you. The withholding rate is 24% (backup withholding rate).
| Gambling Type | W-2G Threshold | Withholding Threshold |
|---|---|---|
| Slots / Bingo / Keno | $1,200 | $1,200 (no reduction for wager) |
| Poker tournaments | $5,000 net | $5,000 net |
| Sports betting | $600 (if 300x wager) | $5,000 net |
| Horse racing | $600 (if 300x wager) | $5,000 net |
| Lottery | $600 | $5,000 net |
Even if no W-2G is issued (because your win is below the threshold), you are still legally required to report the income. Online gambling operators typically send you a W-2G electronically if you have a qualifying win, even if they don't withhold.
What Is Form W-2G?
Form W-2G ("Certain Gambling Winnings") is issued by the gambling operator when you have a qualifying win. You receive a copy; a copy also goes to the IRS. The form shows your gross winnings, any federal tax withheld, your identifying information, and the type of gambling.
If you receive a W-2G, you must include it on your tax return. If federal tax was withheld, it appears as a credit on your 1040 (just like income tax withheld from a paycheck).
Can You Deduct Gambling Losses?
Yes — but only under specific conditions:
- You must itemize deductions on Schedule A instead of taking the standard deduction
- Gambling losses can only offset gambling winnings — you cannot deduct more losses than winnings
- Losses cannot be carried forward to future tax years
- You must have contemporaneous records to support your claimed losses
Example: If you won $5,000 and lost $3,000, you must report $5,000 in winnings but may deduct $3,000 in losses if you itemize, resulting in $2,000 net gambling income.
Keep a gambling diary: date, location, type of game, amount won or lost per session. For online gambling, download transaction history from your operator accounts monthly. Most licensed US apps provide this. You'll need it if audited.
State Gambling Taxes
Most states with legal gambling also tax winnings at the state level. State tax rates vary significantly:
| State | Income Tax on Gambling Winnings |
|---|---|
| New Jersey | 3% – 10.75% (based on income bracket) |
| Pennsylvania | 3.07% flat rate |
| Michigan | 4.25% flat rate |
| New York | 4% – 10.9% (based on income bracket) |
| Nevada | 0% (no state income tax) |
| Texas | 0% (no state income tax) |
| Florida | 0% (no state income tax) |
Professional Gamblers: Different Rules
If gambling is your primary occupation and you pursue it full-time as a business, you may qualify as a "professional gambler" under IRS rules. In this case:
- Report income and losses on Schedule C (business income) instead of Schedule 1 + Schedule A
- You may deduct ordinary business expenses (software, travel, home office portion) in addition to losses
- You are subject to self-employment tax (15.3%) on net profit
- Net losses can offset other income
The IRS applies strict standards for professional gambler status. Most recreational players do not qualify. Consult a tax professional before filing as a professional gambler.
