You can deduct gambling losses only if you itemize your deductions. The AMOUNT you deduct may not be more than the amount of gambling income reported on your return. You claim your gambling losses on Schedule A to Form 1040 as a "miscellaneous deduction NOT subject to the 2% limit." A non-resident of the United States cannot deduct gambling losses on Schedule A of Form 1040NR.
