If you win money in a Super Bowl bet on Sunday, remember while you're celebrating that Uncle Sam can be a bit of a party crasher.
No matter where you wager — whether at a casino, through a pool or fantasy league, or at your neighbor's annual bash — the IRS expects you come to clean each year at tax time.
"Any gambling winnings you receive is considered income by the IRS," said CPA Mark Luscombe, principal analyst at Wolters Kluwer Tax & Accounting in Chicago. "You have to report it."
Roughly 22.7 million Americans are expected to wager an aggregate $6 billion on Sunday's matchup between the New England Patriots and the Los Angeles Rams in Atlanta, according to a recent survey from the American Gaming Association. Of those bettors, 1.8 million plan to bet illegally through a bookie, and others are expected to place wagers through online offshore books.
And, of course, there are a ton of other unregulated bets that happen beyond those channels. And while you might be less likely to tell the IRS about smaller amounts you win, just be aware that it is considered taxable income.
For casual gamblers placing wagers through regulated sports betting in states that allow it, the IRS makes it a bit easier for you by placing reporting requirements on the payor (i.e., the casino), as well. A handful of states have legalized sports betting since last May, when the U.S. Supreme Court struck down a 1992 federal law banning it, and more than two dozen others are considering the move, according to the gaming group.
