This includes compensation for performances, endorsements, the sale of merchandise, and royalty, or other, income closely related to the event. Consequently, you are required to file a U.S. federal income tax return to report and pay any U.S. tax. Generally, if you are a nonresident alien entertainer or athlete performing independent personal services or participating in athletic events in the United States, you are subject to the following special tax and withholding rules. Payments to Foreign Athletes and Entertainers are subject to special withholding rules. Refer to Artists and Athletes (Income Code 20) in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities. A Central Withholding Agreement (CWA) is a tool that can help reduce withholding for non-resident athletes and entertainers who plan to work in the United States. A CWA provides for the correct amount of withholding based upon net income.
