How federal reporting thresholds actually work

Casinos issue Form W-2G on a single winning event, not on a session total. For payments made in calendar year 2026 the minimum reporting threshold is $2,000, raised from the $1,200 figure that had stood since 1977 under the One Big Beautiful Bill Act, and indexed for inflation in later years. The payer rules are:

• Slot machines and bingo — $2,000 or more from one win, before subtracting the wager.
• Keno — $2,000 or more, reduced by the amount wagered.
• Poker tournaments — more than $5,000 in net winnings.
• Other wagers — $600 or more when the payout is at least 300 times the amount wagered.
• Regular withholding of 24% generally applies once winnings pass $5,000 on the qualifying wager types, and backup withholding applies whenever a taxpayer identification number is not given.

This application flags single-spin wins at $2,000, matching the 2026 federal threshold. The threshold is adjusted annually for inflation, so confirm the current-year figure before filing and reconcile your flags against the W-2G forms the casino actually issues. A session total that reaches $2,000 across several smaller wins is not a reportable event.

Separately, all gambling winnings are taxable income whether or not a W-2G is issued. Losses may be deducted only against winnings, and only by taxpayers who itemize, unless the activity rises to the level of a trade or business — a determination that depends on facts and circumstances and should be made with your tax professional. Nothing in this application decides that question for you.

The 90% limit on losses, from 2026

For tax years beginning after 31 December 2025, only 90% of wagering losses may be deducted, and the deduction is still capped at total winnings. This applies to itemizers and to filers treating gambling as a trade or business. A player who wins $100,000 and loses $100,000 in the same year now has $10,000 of taxable income despite breaking even — so-called phantom income. Losses still never offset wages or other income, and they do not carry forward.

The Live Tax Position in this application applies the 90% limit to every year from 2026 onward and shows the disallowed portion on its own line, so the set-aside figure reflects what is actually owed rather than net profit.

Repeal is pending, not enacted. On 16 September 2026 the House Ways and Means Committee voted 38–5 to advance H.R. 10357 (the Digital Asset Tax Certainty Act), a digital-asset tax bill into which language restoring the full 100% wagering-loss deduction was added in committee. It has cleared committee only — not the House floor, the Senate, or the President, and because the fix rides on an unrelated bill it could still be narrowed or dropped. Until that changes, 90% is the law, and this application will not assume otherwise. If it is enacted, the figures here and in the Live Tax Position will be updated.

What "professional gambler" actually requires

There is no hourly or weekly requirement in the tax code — no 40-hour rule. Under Commissioner v. Groetzinger, 480 U.S. 23 (1987), the activity must be pursued full time, in good faith, with regularity and continuity, and for the production of income for a livelihood rather than as a hobby. It is a facts-and-circumstances test, weighed against the nine hobby-loss factors of 26 CFR 1.183-2.

• Time and effort matter but are not decisive, and no case sets an hours-per-week threshold. In one non-precedential Tax Court summary decision, roughly 40 hours a week of documented play supported professional status; a single heavy week on a trip would not. Treat any hours figure as illustrative, not a rule.
• Holding another job does not disqualify you, provided the gambling activity is itself regular and continuous through the year.
• Businesslike conduct — contemporaneous logs, separate accounting, demonstrable expertise and a genuine profit motive — is weighed heavily.
• Professional filers report on Schedule C, are subject to self-employment tax on net income, and cannot report a net wagering loss.
• Ordinary and necessary business expenses — travel, lodging, subscriptions — sat outside the wagering-loss cap under Mayo v. Commissioner, 136 T.C. 81 (2011), which the IRS acquiesced to. The phrase sweeping in deductions "incurred in carrying on any wagering transaction" originated in the 2017 Tax Cuts and Jobs Act and was made permanent by OBBBA, which also added the 90% limit. CCA 202111012 reads that language broadly, but no regulation or court has resolved how it sits against Mayo for a professional's ordinary business expenses. Treat it as an open question with your CPA, not a settled deduction.

The Professional Standing card in this application is a readiness check on your own records against these factors. It does not determine your filing status, and no software can. That determination belongs to your CPA or tax attorney.

• All gambling winnings are taxable; losses are deductible only against winnings and only by taxpayers who itemize.

  IRS, Topic no. 419 — Gambling income and losses

• Only 90% of wagering losses are deductible for tax years beginning after December 31, 2025, still capped at total winnings, for itemizers and professional gamblers alike.

• Professional (trade or business) status is a facts-and-circumstances test — full time, in good faith, with regularity and continuity, for the production of income for a livelihood. There is no statutory hour requirement.

  Commissioner v. Groetzinger, 480 U.S. 23 (1987)

• The taxpayer's own responsibility to keep an accurate diary or similar record of winnings and losses, supported by verifiable documentation. This is the standard the platform's sealed session log is designed to satisfy.

• Slot machine gains and losses determined on a session basis. The optional safe harbour proposed in Notice 2015-21 was never finalised; the supporting authority is two memorandum opinions, which are persuasive rather than binding.

• A professional gambler's ordinary business expenses were historically deductible in full, outside the section 165(d) wagering-loss cap. The OBBBA amendment now folds deductions 'incurred in carrying on any wagering transaction' into that cap, and the interaction is untested.
