Gambling losses are deducted on Schedule A as a miscellaneous deduction and are not subject to a 2% limit. This means that you can deduct all losses up to the amount of your winnings, not just the amount over 2% of your adjusted gross income.
You report gambling winnings as other income on line 21 of Form 1040, but you must itemize to deduct losing bets. If you have few other expenses to claim on Schedule A, it probably won't be worth sacrificing your standard deduction amount just to limit or erase your taxable winnings. Do the math to make sure.
