Help with Tax Questions - International Taxpayers


There are several ways for getting tax information on our website. Our Interactive Tax Assistant tool takes you through a series of questions and gives you immediate responses to many tax law questions. The Frequently Asked Questions and Answers for Individuals and Tax Topics give you instant access to a variety of tax information. Our Tools page has additional self-service options. International taxpayers can find answers on our FAQs About International Individual Tax Matters page.
