Instructions for Form W-7

Purpose of the W-7

The IRS issues ITIN's to foreign nationals and others who have federal tax reporting or filing requirements and do not qualify for social security numbers ("SSNs"). A non-resident alien individual not eligible for a SSN who is required to file a U.S. tax return only to claim a refund of tax under the provisions of a U.S. tax treaty needs an ITIN.

  • A nonresident alien required to file a U.S. tax return
  • A U.S. resident alien (based on days present in the United States) filing a U.S. tax return
