To participate in the Community Volunteer Income Tax Program (CVITP) 

You must first register as a volunteer with the CVITP at If you intend on transmitting returns by EFILE under the CVITP, you must also apply for an EFILE number.

How can I apply?

Your first step in becoming an electronic filer is to complete the EFILE Registration Online form. This is a one-time application, but in some situations you will have to submit revised information. Successful applicants will also be required to renew their application on a yearly basis.

The online application is designed primarily for those operating a tax preparation business. However, individuals may also apply to become electronic filers. Individuals, who are not operating a tax preparation business, should provide their full legal name in the "Name of proprietorship, partnership, or corporation" field and they should also select "Proprietorship" in the "Business Type" field, when completing the online application.

As of October 17, 2022, you can enter up to fifteen applicants instead of four. You will also be asked to provide the RepID for each applicant on your EFILE registration form. Employees who prepare returns in the course of their employment should not be listed as applicants, unless they otherwise meet the definition of an EFILE applicant. Please ensure you review the definition of an EFILE applicant linked above. These changes will enable the CRA to further automate the EFILE suitability screening process and link applicants to representative credentials to support effective monitoring of EFILE activities and services. 

If you do not have a RepID, you can register for one at Represent a Client. It’s fast and easy, especially if you have already registered with My Account or My Business Account. 

Note :  Individuals and businesses who apply with the intention of using EFILE to file a minimal number of returns (or no returns) are not considered to be providing tax preparation services and will be denied access to EFILE. 

Access to the EFILE Electronic Filing Service is limited solely for the purpose of the electronic filing of  any return of income. Any other use is prohibited.

All applications must be made online.

There is no fee for processing your application.

Electronic filing of T1 returns requires the use of a certified software product.

Issuance of EFILE number and password

The system will verify the submitted information and will generate error messages, if necessary. For example, if you forget to complete a mandatory field, such as the "Name of the proprietorship, partnership or corporation", there will be a message advising you of the error. Make any required corrections and resubmit the online form. Once the application has been accepted, the system will display a confirmation page similar to the sample below. The confirmation page will contain your EFILE number and password.
