IRS Form 8802 (U.S. Residency Certification) Fax Numbers
Where and How to Fax a 8802 Form?
IRS Form 8802 is an application used by U.S. taxpayers to initiate the process of obtaining an official certification of U.S. residency. In essence, it’s a formal request that signals to the IRS that you need documentation affirming your residency status for purposes outside the ordinary filing of income tax returns.
What is an IRS Form 8802?
When you submit Form 8802, you are asking the IRS to issue a certification (commonly delivered as Form 6166) that verifies your status as a U.S. resident for tax purposes. This certification is used primarily to claim treaty benefits, for example to secure reduced tax withholding rates or exemptions on certain types of income under a tax treaty between the United States and a foreign country. Essentially, it validates your residency status in the eyes of foreign tax authorities, thereby helping you avoid or reduce double taxation.

How much does it cost to file Form 8802?
Form 8802 carries a nonrefundable IRS user fee: $85 per application for an individual applicant, or $185 per application for a business, trust, estate, or other non-individual applicant. The fee applies once per Form 8802 submitted, regardless of how many countries or tax years the certification covers.
How long does it take to get Form 6166 after faxing Form 8802?
The IRS advises submitting your application, including full payment, at least 45 days before you need your Form 6166. If your request will take longer, the IRS says it will contact you after 30 days to let you know about the delay.
What's the difference between Form 8802 and Form 6166?
Form 8802 is the application you submit to the IRS. Form 6166 is the actual residency certification letter the IRS issues once your Form 8802 is approved, that's the document a foreign tax authority or institution will actually ask to see, not a copy of your Form 8802.
Can I request certification for more than one country on a single Form 8802?
Yes, and the IRS specifically encourages it. Since the user fee applies per Form 8802 submitted rather than per country, listing every country and tax year you need certification for on one application avoids paying the $85 or $185 fee multiple times.
Is there a deadline for requesting a current-year Form 6166?
There's no fixed filing deadline, but the IRS won't accept an early request. A current-year Form 8802 postmarked before December 1 of the prior year will be returned to you unprocessed, so the earliest you can request next year's certification is December 1 of this year.
Requesting a U.S. residency certification is often just one step in a larger cross-border tax filing. Here's what else comes up around treaty benefits and IRS documentation by fax.
