@sj2445 It depends on what state you live in, what state the gambling winnings are from, how much you won, and possibly what type of gambling it was. Every state has different rules. Start by checking the taxation web site for the state that the winnings are from, to see what the filing requirements are for a nonresident. If the state that you live in has income tax, you almost certainly have to report the winnings as income on your resident state tax return, whether or not you are required to file in the state that the winnings are from. If you have to report the income in both states, one state will give you credit for the tax that you pay to the other state. Exactly how that works depends on what the two states are.
