W-2G thresholds, withholding, and session accounting
Last updated April 2026. General info, not tax advice — consult a CPA for your situation.
Gambling winnings are taxable income in the US. The casino reports certain wins to the IRS via Form W-2G; you owe tax on the rest whether or not the casino reports it. Two things to plan for: paperwork at the table, and what you actually owe at year-end.
W-2G triggers (when the casino hands you the form):
- Slots / video poker / bingo: $1,200+ on a single jackpot
- Keno: $1,500+ net (winnings minus the wager)
- Poker tournaments: $5,000+ net
- Table games (blackjack, craps, baccarat, roulette): generally no W-2G, regardless of amount — but you still owe tax on net wins. The threshold is "300:1 AND $600+" which almost no table-game bet hits.
Federal withholding:
- 24% federal withholding kicks in on most W-2Gs. You can be backup-withheld at 24% if you don't furnish a TIN.
- Withholding is a prepayment, not a final tax — your real bill depends on your bracket.
Session accounting (the rule almost everyone gets wrong):
The IRS uses a "gambling session" framework for non-W-2G play (Tschetschot, Notice 2015-21). A session is one continuous period at one type of game. You report the net of that session. You can't just net wins and losses across the year unless you're a professional gambler.
- Recreational (most users): report each winning session as gross income; deduct losses as itemized deductions, capped at total winnings, only if you itemize. Standard-deduction takers can't deduct losses at all — the law as of 2026.
- Professional (rare, qualifies as a trade or business): file Schedule C, deduct expenses, deduct losses against winnings.
State tax layers on top. Some states (NV, FL, TX, WA, TN, AK, SD, WY) have no state income tax. Some states (NJ, IL, IN, MI) tax gambling winnings as regular income. A few states even disallow loss deductions — winning $5,000 then losing $5,000 in MI, IL, or CT can leave you owing thousands in state tax on a break-even year.
Form 5754 comes up when you a jackpot — it lets the casino issue separate W-2Gs to each winner instead of one big one to the lead bettor.
Practical rules of the road:
- Keep a contemporaneous log of every session: date, casino, game, buy-in, cashout, time. The session log in TableSharp is built for this.
- Save your W-2Gs all year. The IRS gets copies; mismatch triggers correspondence audits.
- If you're a counter or cardroom regular, talk to a CPA who handles gambling income. The session rules and pro vs. recreational status meaningfully change your bill.
Nothing here is tax advice. Rules change, your state's rules vary, and your specific bracket and situation matter — when the numbers get real, talk to a professional.
