Key Takeaways
- For the 2026 tax year, casinos must follow the $2,000 threshold for Form W-2G reporting on all game types. In addition to the dollar amount, sports wagering and certain other wagering transactions must also meet the 300-times-the-wager rule.
- Reporting and withholding are separate rules. Regular gambling withholding does not apply to bingo, keno, or slot machine winnings, while regular withholding does.
- If a winner does not provide their TIN, the casino must withhold 24% of reportable gambling winnings that are not subject to regular gambling withholding.
- Casinos must furnish 2026 Forms W-2G to winners by February 1, 2027. Forms filed with the IRS are generally due March 1, 2027, on paper or March 31, 2027, if filing electronically.
- Form W-2G reporting and federal cash reporting ($10,000 cash reporting rule) are two separate requirements. One payout could trigger either rule, both, or neither.
Casinos make thousands of payouts each year, and some of these payouts may require federal reporting using Form W-2g. The form is required depending on the game, the amount won, and sometimes on how the win compares to the wager.
Understanding the Casino IRS Reporting Requirements for Tax Year 2026
Casinos use Form W-2G to report certain gambling winnings and any taxes they withhold. Whether this form is needed depends on the game, the amount won, and sometimes on how the win compares to the wager.
The IRS sorts these rules into five groups: horse racing, dog racing, jai alai, and certain other wagering transactions; sweepstakes, wagering pools, and lotteries; bingo, keno, and slot machines; poker tournaments; and sports wagering.
Each group has its own rules, so casino IRS reporting requirements vary by game. Casinos need to check the correct rules for each payout type.
What Is Form W-2G?
Form W-2G is the form casinos use to report certain gambling payouts and any tax withheld from them. A Form W-2G casino filing lists the winner’s name, address, and TIN, along with the date of the gambling winnings, the type of wager, and the amount withheld.
Casinos send a copy to the IRS and give the winner a copy. For bingo, keno, and slot machines, casinos may be able to use an optional aggregate reporting method where multiple payouts received by the same winner during a 24-hour gaming day may be reported on a single Form W-2G, instead of filing one form per payout.
Tax year 2026 Reporting Threshold for Form W-2G
The biggest change for Tax Year 2026 (2027 filing season) involves changes in the casino IRS reporting requirements. Starting with payments made after December 31, 2025, the W-2G threshold is now $2,000 for certain gambling winnings.
However, the $2,000 threshold is not used for every reportable gaming activity. The next section breaks down exactly how it applies to each type of gambling.
Casino Winnings Reporting Requirements
| Game | 2026TY Reporting Rule |
|---|---|
| Slot machines | Report winnings of $2,000 or more. |
| Bingo | Report winnings of $2,000 or more. |
| Keno | Report winnings of $2,000 or more, after subtracting the wager. |
| Poker tournaments | Report net winnings of $2,000 or more after subtracting the wager or buy-in. |
| Sports wagering, Sweepstakes, wagering pools, lotteries, Horse racing, dog racing, jai alai | Report winnings of $2,000 or more, and only if they are also 300 times the wager or higher. |
What Are the Withholding Requirements for Form W-2G?
Reporting a win and withholding tax from it are two different steps. A casino can owe one without owing the other.
Casinos withhold 24% of the winnings when the payout, minus the wager, comes to more than $5,000, and the game is a sweepstakes, wagering pool, lottery, or a racing or sports bet that also pays at least 300 times the wager.
Bingo, keno, and slot machine winnings do not have gambling backup withholding, no matter how large the payout is, but backup withholding may apply.
Casinos have to report any tax withheld in box 4 of Form W-2G, then file Form 945 to report the full year’s total to the IRS.
TIN Requirements for Casino Winnings
Casinos need the winner’s Social Security Number (SSN) or other TIN to file Form W-2G.
If a winner does not provide a correct TIN and the payout meets the reporting threshold, the casino must withhold 24% of the winnings and any required 300-times-the-wager test, unless regular gambling withholding already applies. This rule applies even to bingo, keno, and slot machine wins, which would not otherwise require withholding.
Information Casinos Must Collect from Winners
To complete Form W-2G, casinos need to collect a few key details from the winner, depending on the gaming type:
- Full legal name, address, and TIN of the winner
- Amount won and the date of the win
- Type of wager placed
- Two forms of ID, one of which must include a photo
A signed Form W-9 can work as an acceptable non-photo ID. Tribal casinos can skip the photo requirement for members of federally recognized tribes who show a tribal ID card. State lottery winners are not subject to this ID rule.
Reporting Shared Gambling Winnings
A winning ticket does not always belong to one person. When a group shares a win, the person who receives the winning fills out Form 5754, Statement by Person(s) Receiving Gambling Winnings, listing each winner’s name, address, TIN, and share of the payout.
The casino uses this form to prepare a separate Form W-2G for each winner. Withholding is calculated based on the total winnings from the shared wager, minus the amount wagered, before dividing the winnings among the individual winners. Form 5754 itself is never sent to the IRS. The casino keeps it on file.
Tax Reporting for Noncash Casino Prizes
Not every casino prize is paid in cash. In some cases, winners may be awarded a car, a vacation package, or another item that still counts as a taxable win. Casinos use the item’s fair market value to figure out the value of the winnings.
If the casino pays the withholding tax itself rather than deducting it from the winnings, the tax must be added to the winnings with an effective withholding rate of 31.58%.
Tax Reporting for Foreign Casino Winners
Foreign winners follow a different reporting process entirely. A nonresident alien or foreign entity does not receive a Form W-2G.
Instead, the casino generally withholds 30% of the winnings and reports the payment on Form 1042-S, with the withholding itself reported separately on Form 1042.
Form W-2G Deadlines That Casinos Must Follow
| Requirement | 2027 Deadline | Reason For The Shift in Due Date |
|---|---|---|
| Furnish Form W-2G to the winner | February 1, 2027 | January 31 falls on a Sunday. |
| Paper file Form W-2G with IRS | March 1, 2027 | February 28 falls on a Sunday. |
| eFile Form W-2G with IRS | March 31, 2027 | None. |
Note: Casinos that file 10 or more information returns in total across all form types must eFile rather than file on paper.
The IRS is also shutting down its older FIRE system for the next filing season. After January 1, 2027, IRIS will become the only system for filing current, prior year, and corrected returns. Casinos still using FIRE should set up IRIS access before the 2027 filing season starts.
Form W-2G vs. the $10,000 Reporting Rule
Form W-2G reporting is not the same as the $10,000 cash reporting rule or the Currency Transaction Report requirement, and casinos should not confuse the two.
Form W-2G reports the gambling winnings reporting obligations tied to a payout. A separate rule under the Bank Secrecy Act requires casinos to file a Currency Transaction Report when a customer’s cash transactions total more than $10,000 in a single gaming day, win or lose.
A single payout can trigger Form W-2G reporting rule, the cash rule, both, or neither. Casinos need to evaluate each requirement separately.
FAQs
1. Do casinos report gambling winnings to the IRS?
Yes. Casinos report qualifying gambling winnings to the IRS on Form W-2G once a payout meets the reporting threshold. Slot machines, bingo, keno, poker tournaments, and sports wagering each follow their own dollar threshold.
2. How much can someone win before a casino reports it?
For the 2026 tax year, the general threshold is $2,000 for certain games. Sports wagering and racing wins must also meet at least 300 times the wager.
3. Do casinos automatically withhold 24% from Form W-2G winnings?
No. Reporting a win and withholding tax on it are separate rules. A casino can file Form W-2G without owing any withholding. The regular 24% gambling withholding generally applies when winnings minus the wager exceed $5,000 for certain types of gambling.
4. What happens if a winner refuses to provide an SSN?
If a winner does not provide a correct SSN and the payout meets the reporting threshold, the casino generally must withhold 24% of the winnings as backup withholding. This applies even to bingo, keno, and slots.
5. Do casinos report gambling winnings on Form 1099?
Generally, no. Qualifying gambling winnings are reported on Form W-2G, not on a standard Form 1099. Casinos would use only a Form 1099 series for gambling-related payments that fall outside the reportable categories of Form W-2G.
