Updated October 19, 2026. Quick answer: Box 1 of Form W-2G shows the reportable gambling winnings the payer paid you, and box 7 shows additional winnings from identical wagers. Whether a payment is reportable depends on the type of gambling and, for most games, on the winnings compared with the wager. The winner copy says to report gambling winnings on the Other income line of Schedule 1 and gives the loss rule in the same paragraph.
What box 1 reports
On the form, box 1 is headed Reportable winnings, and the filer instructions describe the purpose of the whole form in one sentence: “File Form W-2G, Certain Gambling Winnings, to report gambling winnings and any federal income tax withheld on those winnings.” The filer instructions are written for the payer, the casino, track, lottery or sportsbook that prepares the form. They are still the best public description of what each box on your copy should contain.
The winner copy tells you when you should expect to receive one: “The payer must furnish a Form W-2G to you if you receive gambling winnings subject to federal income tax withholding.” The filer instructions put the same idea from the payer’s side: “Report gambling winnings on Form W-2G if the winnings are subject to federal income tax withholding (either regular gambling withholding or backup withholding).” The withholding side of the form is covered in Form W-2G box 4 and boxes 13 to 18, and the other boxes are laid out in the Form W-2G boxes guide.
The threshold sentences that exist
The winner copy does not state a dollar threshold. It points elsewhere: “See Pub. 1099 for information on the applicable reporting threshold for each type of gambling winnings.”
The instructions do state the 2026 minimum threshold in their What’s New section. First they explain that the amount now moves: “the minimum threshold amount for reporting certain payments and backup withholding on certain information returns, including the Form W-2G, will be adjusted yearly for inflation.” Then they give the figure: “The minimum threshold amount for payments made in calendar year 2026 is $2,000.”
They also describe the requirements as a combination of factors: “The requirements for reporting and withholding depend on the type of gambling, the amount of the gambling winnings, and generally the ratio of the winnings to the wager.” That is why the next section is organized by game type rather than by a single number.
The 300 times the wager condition, game by game
The filer instructions have five headings, one per type of gambling. The table shows how each one describes the entry in box 1. Three of the five add a condition that the payment be at least 300 times the wager; bingo, keno and slot machines and poker tournaments use different wording.
| Type of gambling | What the payer’s instructions say to enter in box 1 |
|---|---|
| Horse racing, dog racing, jai alai and other wagering transactions (section 1) | “Enter payments that meet or exceed the applicable reporting threshold if the payment is at least 300 times the wager.” |
| Sweepstakes, wagering pools and lotteries (section 2) | “Enter payments that meet or exceed the applicable reporting threshold if the payment is at least 300 times the wager.” |
| Bingo, keno and slot machines (section 3) | “Enter payments that meet or exceed the applicable reporting threshold.” |
| Poker tournaments (section 4) | “Enter payments that meet or exceed the applicable reporting threshold in net gambling winnings from a poker tournament.” |
| Sports wagering (section 5) | “Enter payments that meet or exceed the applicable reporting threshold if the payment is at least 300 times the wager.” |
For lotteries and similar games, the instructions add how the wager enters the picture: “The wager must be subtracted from the total winnings to determine whether withholding is required and, at the option of the payer, to determine whether reporting is required.” For bingo and slot machines they add that “Winnings and losses from other wagering transactions aren’t to be taken into account when determining the applicable reporting threshold.” If you won a prize rather than cash, the instructions for these games say “If the winnings aren’t paid in cash, the FMV of the item won is considered the amount of the winnings.”
Each game type has its own page in this series: lottery and sweepstakes winnings, bingo, keno and slot machine winnings, poker tournament winnings and sports wagering winnings.
Horse racing, dog racing, jai alai and other wagering transactions
No separate page covers these wagers, so the rules for them are here. Section 1 of the instructions says: “File Form W-2G for every person to whom you pay gambling winnings meeting or exceeding the applicable reporting threshold if the winnings are at least 300 times the amount of the wager.”
For parimutuel betting, how the wager is counted matters: “All wagers in horse racing, dog racing, or jai alai placed in a single parimutuel pool and represented on a single ticket are aggregated and treated as a single wager for purposes of determining the amount of the wager for withholding and reporting requirements.” The instructions give a case where two bets are not identical but still combine: “if both bets are represented on a single ticket, then they must be aggregated to determine the amount of the wager.”
If the person who presents the ticket for payment owns it alone, the form carries that person’s own name and number. If another person shares in the ticket, the section sends the payer to the multiple winners rules, which are described in Form W-2G boxes 9, 11 and 12 and Form 5754.
Box 7 and identical wagers
The form labels box 7 “Winnings from identical wagers”. The instructions for horse racing, lotteries and sports wagering all give the same entry: “Enter the amount of additional winnings from identical wagers.” Section 3 for bingo, keno and slot machines instead lists boxes 6 and 7 as “Not applicable.”
Identical wagers are defined in the instructions: “Two or more wagers are identical wagers if they are placed with the same payer and winning depends on the occurrence (or non-occurrence) of the same event or events.” For parimutuel games there is an extra element: “In the case of horse races, dog races, or jai alai, wagers must also be placed in the same parimutuel pool to be identical wagers.” The instructions illustrate it this way: “multiple bets placed in a parimutuel pool with a single payer on the same horse to win a specific race are identical wagers.”
The reason it matters is that “are added together for purposes of reporting and withholding requirements.” So a box 7 entry means the payer treated more than one winning wager as part of the same reporting picture.
Where it goes on the return
The winner copy of the form carries its own instructions for box 1: “Generally, report all gambling winnings under the” Other income line of Schedule 1 (Form 1040). The line itself is discussed on Schedule 1 lines 8a and 8b, and the schedule as a whole on Schedule 1.
The same paragraph addresses losses: “You can deduct 90% of your gambling losses as an itemized deduction, but the amount you deduct cannot be more than the amount of your winnings.” Itemized deductions are discussed at Form 1040 line 12, and the income and adjustment totals are covered at Form 1040 lines 9, 10 and 11.
The paragraph also tells you how to document it: “Keep an accurate record of your winnings and losses, and be able to prove those amounts with receipts, tickets, statements, or similar items that you have saved.” It points to “Pub. 529 and Pub. 525” for more.
Noncash prizes and box 1
When a payer pays the withholding on a noncash prize, the instructions say how box 1 changes: “If you use method 2, enter the sum of the noncash payment and the withholding tax in box 1 of Form W-2G and the withholding tax paid by the payer in box 4.” The two methods are described in Form W-2G box 4 and boxes 13 to 18.
Edition and box numbers
This page reads Form W-2G (Rev. January 2026) and the Instructions for Forms W-2G and 5754 (Rev. January 2026), the current files irs.gov served on 2026-10-19. The instructions state: “Form W-2G and its instructions have been converted from an annual revision to continuous use.” They add: “Both the form and instructions will be updated as needed.” No earlier edition is compared on this page. Check the version printed on the form you received, because box numbers and wording can change when a form is updated.
Common mistakes
- Looking for a dollar threshold on your winner copy. It says only “See Pub. 1099 for information on the applicable reporting threshold for each type of gambling winnings.”
- Treating every game the same. The instructions for bingo, keno and slot machines say “Enter payments that meet or exceed the applicable reporting threshold.” while the other games add a condition about the wager.
- Deducting more losses than winnings. The winner copy says “the amount you deduct cannot be more than the amount of your winnings.”
