W-2G Filing Instructions: How to File Form W-2G Correctly for Gambling Winnings

Introduction

Form W-2G reports gambling winnings and any federal tax withheld from them, but the reporting and withholding rules change depending on the type of wager or gambling activity.

In this blog, we’ll walk payers through the current Form W-2G instructions, reporting thresholds, withholding rules, and filing deadlines.

Understanding Form W-2G and Filing Requirements

Form W-2G reports gambling winnings subject to federal income tax withholding, including regular gambling withholding or backup withholding. The minimum threshold for Form W-2G filing requirements depends on the gambling activity.

When Form W-2G Applies

• Lotteries, sweepstakes, wagering pools, horse racing, dog racing, jai alai, and sports wagering: Report only if the winnings meet or exceed the $2,000 threshold and are at least 300 times the wager.
• Bingo, keno, and slot machines: Reporting depends on whether the winnings meet the $2,000threshold or not. The 300-times-the-wager rule does not apply. For keno, subtract the wager for the winning game
• Poker tournaments: The net winnings should meet or exceed the applicable threshold after subtracting the buy-in.

Form W-2G withholding rules

• Regular gambling withholding: 24% withholding applies when the winnings minus the wager are more than $5,000. For horse racing, dog racing, jai alai, sports wagering, and other wagering, the winnings must also be at least 300 times the wager.
• Backup withholding: 24% backup withholding applies to reportable winnings if the winner doesn’t provide a correct TIN and the payment is not already subject to regular gambling withholding.
• Noncash payments: Withhold 24% of the fair market value minus the wager if the winner pays the tax. If the withholding tax is paid, withhold 31.58% of the fair market value minus the wager.

Form 5754 Instructions

Use Form 5754 only when the person receiving the winnings isn’t the actual winner, or when two or more people share a single winning ticket. Prepare a separate Form W-2G for each winner. Do not send this form to the IRS.

Step-by-Step Instructions on how to file Form W-2 G

These step-by-step w2g filing instructions cover the sequence every payer needs to follow, whether the payout comes from a slot machine, a sportsbook, or a shared lottery ticket.

1. Identify the wager type

Check which wager it is. Some wagers, like sports wagering, slot machines, keno, poker tournaments, etc., each follow different reporting rules.

2. Apply the reporting test

Check whether the winnings meet the $2,000 threshold and, where it applies, the 300-times-the-wager rule.

3. Determine withholding

Confirm whether regular gambling withholding or backup withholding applies before the payment goes out.

4. Collect the winner’s information

Get the winner’s name, address, and TIN, plus two forms of identification where required, including one with a photo. Get a signed Form W-9 from the recipient to use as the nonphoto identification document.

5. Use Form 5754 for shared winnings

If the winnings are shared among a group of people, use a Form 5754 to split and report the gambling winnings split correctly.

6. Complete Form W-2G

Report the winnings, date, wager information, winner details, and any regular or federal tax withheld, following the correct W-2G instructions for the wager type.

7. File Form 945 if withholding applies

Report regular or backup gambling withholding also gets reported annually on Form 945.

8. Meet the deadlines

For 2026 payments, furnish recipient copies by February 1, 2027, file paper returns with the IRS by March 1, 2027, and eFile returns by March 31, 2027.

9. eFile through IRIS

Payers filing 10 or more information returns, combined, must eFile. And since FIRE is retiring at the end of 2026, eFile only through IRIS or 1099Online (we support IRIS filing)

Form W-2G Penalties and Corrections

Filing Form W-2G late or using incorrect information can trigger information return penalties under IRC Section 6721 if the W-2G instructions aren’t followed correctly. The penalty starts at $60 per return if filed within 30 days after the filing deadline, and can go up to $340 per return if corrected after August 1 or not filed.

Common Correction Triggers for Form W-2G

• Using the wrong TIN or winner name
• Reporting the wrong winnings amount and incorrect withholding amount
• Failure to use Form 5754 for group winnings

How to handle corrections on Form W-2G

• For incorrect winnings, withholding, dates, or other reporting details, correct the mistake and file one corrected Form W-2G.
• For an incorrect winner name or TIN, file a corrected return with the original information and zero amounts, then file a new original return with the correct data.
