The US: Winnings as Ordinary Income
The IRS treats every dollar of gambling winnings as ordinary income, subject to federal income tax at your marginal rate. Casinos are required to issue a W-2G for certain large wins. Recreational players can offset winnings with losses — but only if they itemize deductions, which fewer taxpayers do since the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction. Professional players have more flexibility via Schedule C but also face self-employment tax.
Why the UK Is So Favorable
The UK abolished gambling winnings tax in 2001. The government determined it was more efficient to tax operators (who pay a 15% Remote Gaming Duty) rather than players — partly because taxing winners was difficult to enforce and discouraged players from using licensed, regulated operators. This has made the UK one of the most player-friendly jurisdictions in the world for poker and casino gaming.
Recreational vs. Professional Status
In countries where gambling income can be taxed (US, Canada, Australia), the distinction between recreational and professional play is critical. A professional gambler — someone who relies on gambling as their primary source of income and conducts it in a business-like manner — faces different (often higher) tax obligations, but may also deduct business expenses like software, travel, and coaching. Tax authorities set a high bar for professional classification and may challenge it, so strong record-keeping is essential.
The Crypto Complication
Crypto gambling sits at the intersection of two complex tax areas. In the US, the IRS has been clear that crypto is property, not currency — so every time you convert crypto to fiat (or spend it) you potentially trigger a capital gains event. A player who wins 1 BTC when it is worth $50,000 and later sells it for $80,000 owes tax on both the original winnings and the $30,000 capital gain separately. Keeping a detailed ledger of all transactions is non-negotiable for compliant reporting.
State and Local Taxes
In the US, most states also tax gambling winnings at rates ranging from 0% (Nevada, Florida) to over 13% (California). Some states do not allow itemized loss deductions at all, even if the federal return allows them. This calculator covers federal taxes only — add your state's rate to get a more complete picture. Similarly, Canada and Australia have provincial/territorial taxes that add to the federal rate.
