ITIN Application

Individual Taxpayer Identification Number

An Individual Taxpayer Identification Number (or ITIN) is a U.S. tax number issued by the Internal Revenue Service (IRS).

W7 application

ITINs are issued regardless of immigration status or residency, on the basis of the Internal Revenue Code. In most cases, the application (the W-7 form) must accompany a U.S. federal income tax return.

Serge Gautron is a Certifying Acceptance Agent (CAA).


A Certifying Acceptance Agent (CAA) is a person who is authorized, under an agreement with the IRS, to complete and submit a W-7 form on behalf of the applicant without providing documentary proof of support to the IRS. You, the applicant, keep your passport and do not need to send it to the IRS. Instead, we, the CAA, certify that we have reviewed the documents proving your identity and alien, to the US, status based on the documentation itself.

Serge can help with your W-7

First, we complete the W-7 ITIN application for you.
We certify your passport, or other identifying documents, for the purposes of this application, you go home with your originals.

We also ensure that all other supporting and required documentation is included with your submission.

In addition, as a Certifying Acceptance Agent I am able to contact the IRS to determine the status pf your application.

Note: Notarization by a Canadian lawyer, barrister or solicitor will not be effective for the purpose of the W-7 ITIN application. Consequently, choosing a Certifying Acceptance Agent is necessary for Canadians in particular.
