Internal Revenue Service 1 article

Internal Revenue Service is the U.S. federal tax agency, and gambling enters its remit through the taxation and reporting of winnings, wagering-related business obligations, withholding rules and certain federal excise taxes. Casinos, sportsbooks and players may encounter IRS forms or reporting requirements depending on the transaction and taxpayer circumstances. The agency's role is tax administration and enforcement, not gaming licensing or market supervision, so state gambling regulation remains a separate layer.
