Form 8802 is the application for U.S. residency certification. The IRS says it is used to request Form 6166, a letter of U.S. residency certification for claiming benefits under an income tax treaty or VAT exemption. RepeatForm helps when you apply again: upload a Form 8802 you completed and the current blank, then review.
Tested with the irs.gov edition dated Rev. October 2026
The IRS instructions say "Form 8802 is used to request Form 6166, a letter of U.S. residency certification for purposes of claiming benefits under an income tax treaty or VAT exemption. You cannot use Form 6166 to substantiate that U.S. taxes were paid for purposes of claiming a foreign tax credit." RepeatForm does not decide whether you qualify.
Form 8802 is the application; Form 6166 is the certification letter the IRS sends back. On line 3a of the form you give the address where to mail Form 6166, and line 3b is for an appointee. RepeatForm helps with the application only.
The instructions say "A Form 8802 application(s) will not be processed until the nonrefundable user fee is paid." They advise you to "mail your application, including full payment of the user fee, at least 45 days before the date you need to submit Form 6166." The fee changed on October 1, 2026, so this page gives no amounts: read the current instructions on irs.gov.
The form has a signature line with the date and daytime phone number, and says "Spouse's signature. If a joint application, both must sign." RepeatForm carries the date but not the signature, so you sign by hand.
Upload a Form 8802 you completed and the current blank; RepeatForm carries the matching answers across; you review them, then preview the PDF before you export. The applicant, address and appointee details are the part you save retyping.
The IRS publishes a new Form 8802 when the form changes. Carrying an earlier copy into the new one works for many answers, but some fields are renamed or moved and match only partly, so check every line on the new form in Review before you export.
The individual return the certification relates to: Form 1040.

The IRS instructions say "Form 8802 is used to request Form 6166, a letter of U.S. residency certification for purposes of claiming benefits under an income tax treaty or VAT exemption." RepeatForm helps you reuse the details; it does not decide who is eligible.
The instructions say to mail the application "at least 45 days before the date you need to submit Form 6166," and "We will contact you after 30 days if there will be a delay in processing your application." RepeatForm cannot say how long yours will take.
The fee is set by the IRS and changed on October 1, 2026, so this page does not repeat an amount. The instructions state it, and say "A Form 8802 application(s) will not be processed until the nonrefundable user fee is paid." RepeatForm does not pay it for you.
You can reuse the applicant's name and taxpayer identification number, address and appointee information where they match. The certification year, countries and payment change, so enter them again and check every line in Review. The date carries but the signature does not: sign by hand.
