Form W-2G in 2026: What It Reports and Why It Isn't the Whole Story

A casino or sportsbook files Form W-2G for some large wins. For 2026 the reporting threshold for bingo, keno and slot machine winnings is $2,000 (Instructions for Forms W-2G and 5754); other kinds of wagers have their own thresholds, and a sportsbook win may be reported on a W-2G — compare with the forms you receive.

Report everything

All gambling winnings are taxable, with or without a form (Topic 419). Your return should show at least what your Forms W-2G add up to. Tax withheld (box 4) goes on Form 1040 line 25b.

Wagertally lets you type your W-2G totals and warns if they're more than the winnings in your bet history.
