⚠️ CRITICAL: All Gambling Winnings Are Taxable Income
- The IRS requires you to report ALL gambling winnings, regardless of amount
- This includes casino wins, sports betting, poker tournaments, lottery prizes, and raffles
- Even if you didn't receive a W-2G form, you must report the income
- Failure to report can result in penalties (20-40%), interest, and potential audit
- Casinos report W-2G forms to the IRS, so they know about winnings over thresholds

| Keno | $1,500 or more | 24% if >$5,000 |
| Poker Tournaments | $600 or more | 24% if >$5,000 |

| Lottery | $600 or more | 24% if >$5,000 |
| Other Gambling | $600 or more (300x wager) | 24% if >$5,000 |
If winnings exceed $5,000, the casino will withhold 24% for federal tax. You can claim a refund if over-withheld when filing. W-2G guide →
💰 How to Calculate Federal Tax on Gambling Winnings
📝 Step-by-Step Calculation
- Step 1: Total all gambling winnings for the year (including W-2G and non-W-2G wins)
- Step 2: Add winnings to your other income (salary, investments, etc.)
- Step 3: Determine your marginal tax bracket based on total income
- Step 4: Calculate tax on winnings at your marginal rate
- Step 5: Subtract any withholding already paid by the casino
- Step 6: Deduct gambling losses (up to winnings) if itemizing on Schedule A
📊 Example Calculation
- Salary: $60,000
- Slot Winnings: $8,000 (W-2G issued, $1,920 withheld)
- Poker Winnings: $500 (no W-2G)
- Total Winnings: $8,500
- Total Income: $68,500
- Marginal Tax Rate: 22%
- Tax on Winnings: $8,500 × 22% = $1,870
- Withholding Paid: $1,920
- Tax Due/Refund: $1,870 - $1,920 = ($50 refund)
⚠️ Penalties for Not Reporting Gambling Winnings
| Violation | Penalty | Additional |
|---|---|---|
| Failure to report income | 20% of underpaid tax | + interest on unpaid tax |
| Negligence or disregard of rules | 20% of underpayment | + accuracy-related penalty |
