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.
If you are from a non-treaty country, then you will need to deduct your gambling losses from your prize winnings to obtain a partial or full gambling tax refund. Remember, the income code on your IRS Form 1042-S must read 28 in order to claim an IRS tax refund.
