Certificate of Foreign Status

Last updated Monday, September 20, 2021

Payments made to a “foreign national non-resident alien for tax purposes” who performs services outside of the United States are not subject to federal Withholding tax, Social and Medicare tax, nor is there any U.S. reporting obligation. In order to certify that they are not a U.S. citizen or resident of the U.S., the foreign national will need to follow the below steps.

  1. Download and complete the Certificate of Foreign Status and Activities/Services Performed Outside of the United States (PDF) form.
  2. Locate and make a copy of documentation that serves as proof of citizenship and residency, such as a passport or residency card.
  3. A confirmation letter (essentially, a letter of support) stating that all services will be performed outside of the United States. A confirmation letter template (Word doc) is available.
  4. Return the completed form and supporting documents to the ISC Payroll Office via one of the following methods:
