Form 8802 is the IRS Application for United States Residency Certification. It is used to request a Form 6166, which certifies that a U.S. person or entity is a resident for tax treaty purposes.
Plain English
If you need official proof that you or your business are a U.S. tax resident—usually to claim treaty benefits abroad—you fill out Form 8802. The IRS then issues a residency certificate (Form 6166) that foreign tax authorities accept.
