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.
To claim your gambling losses, you have to itemize your deductions. Gambling losses are a miscellaneous deduction, but -- unlike some other miscellaneous deductions -- you can deduct the entire loss. The deduction goes on line 28 of Schedule A and you have to note that the deduction is for gambling losses.
