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 IRS Tax Map, Frequently Asked Questions and Answers for Individuals, and Tax Topics also 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.
