Key Takeaways

  • Form 8802 requests a U.S. residency certificate on Form 6166.
  • Form 6166 is not proof that U.S. tax was paid.
  • A foreign-owned LLC does not automatically make the owner eligible for Form 6166.
  • The correct applicant should be identified before filing.

Form 8802 requests Form 6166, not proof that taxes were paid

The IRS says Form 8802 is used to request Form 6166, a letter of U.S. residency certification for claiming treaty or certain VAT-related benefits. It also says Form 6166 cannot be used to prove U.S. taxes were paid for foreign tax credit purposes.

This distinction matters because many founders ask for a 'residency certificate' without first confirming who is actually claiming U.S. residency.

Why digital nomads should be careful here

A foreign owner with a U.S. LLC does not automatically become a U.S. resident who can obtain Form 6166 personally. The IRS evaluates the applicant's U.S. residency for tax purposes. In some structures, the individual will not qualify even though the LLC exists. In others, a corporation or other taxpayer may be the relevant applicant.

This is why the applicant should be identified before filing Form 8802.

How to avoid wasting time and fees

Review the form instructions, determine which taxpayer is asking for certification, and file early enough because the IRS advises sending the application at least 45 days before the certificate is needed. Do not use Form 8802 as a generic substitute for actual treaty analysis.

It is an administrative certificate, not a magic tax solution.
