This question comes up a lot as people find themselves regularly participating in the social ill of gambling. Most people lose far more than they win. That's why gambling is so stupid. But what if you "get lucky" and win a chunk of money. Do you have to report it? What if you've lost far more than you've won? Then do you have to report it?

The rules surrounding gambling are simple. Any money you win (from lotteries, raffles, horse racing, casinos, etc.) is taxable. The same goes for any prizes you win, such as cars, electronics, trips, or real estate. You may get a form W-2G to document your winnings, but even if you don't get one, you're responsible for reporting the gambling income.

Your gambling income goes on line 21 of Form 1040. Any gambling losses that you have documented can go on Schedule A of Form 1040. However, you can't deduct more than your gambling winnings. You have to keep accurate records of your winnings and losses. Most people don't seem to do that, but it's what the law requires. Be careful: This is a much-abused part of the tax code because most gamblers don't have records that support their deductions. Don't set yourself up to be audited.

More information can be found on gambling winnings and losses on the IRS website.
