Tax Compliance: IRS May Be Able to Improve Compliance for Nonresident Aliens and Updating Requirements Could Reduce Their Compliance Burden

摘要

Every year, the U.S. receives millions of legal visits by foreign individuals. Nonresident aliens--who are neither U.S. citizens nor residents--may be required to file a federal tax return if they earn U.S.- source income, and their noncompliance can contribute to the tax gap. As with U.S. citizens and residents, the Internal Revenue Service (IRS) is responsible for ensuring that nonresident aliens fulfill their tax obligations. GAO was asked to (1) identify what data are available on nonresident alien tax filing and compliance, (2) provide information on guidance IRS provides to nonresident aliens and third parties on tax requirements and any challenges associated with filing, and (3) assess actions IRS takes to enforce nonresident alien tax compliance. To meet its objectives, GAO examined IRS and other federal agency documentation, reviewed tax filing and other data, and interviewed IRS officials and other third parties.
