Form 8802 is the application
The IRS Form 8802 instructions say Form 8802 is used to request Form 6166 for claiming treaty benefits or a VAT exemption.
Tax Paperwork can organize known Form 8802 facts in a local draft, but it does not submit the application or pay the user fee.
Form 6166 is the output
The IRS Form 6166 page describes the certification of U.S. tax residency and points applicants back to the Form 8802 instructions.
Tax Paperwork cannot issue Form 6166, speed IRS processing, or monitor whether the certification is accepted by a foreign payer or tax authority.
What to keep
- Signed Form 8802, attachments, payment confirmation, upload confirmation if used, fax or mailing proof, and IRS responses.
- A copy of Form 6166 if issued and any foreign withholding correspondence tied to it.
