A Web access code (WAC) is a personalized code that the Canada Revenue Agency mails to you. The WAC is needed, with other identifiers such as a Business Number or Account Number, to access the secure areas of the CRA's Internet filing Web pages.
Where do you find your Web Access Code?
It is shown above the Business Number on your personalized T4 Summary or on the Web Access Code for Electronic Filing letter that we sent you. The personalized summary and letter also shows your Business Number or Account Number.
Note
You cannot use last year's web access code, as it is only valid for one tax year.
If you do not have a web access code, call our Help Desk at 1-877-322-7849.
What is a Web Access Code comprised of?
The WAC is comprised of six characters. Two of the characters are letters and four are numbers. The letters can be identified with an asterisk below them. The WAC is case sensitive which means you must enter it exactly as it appears on your personalized T4 Summary or Web Access Code for Electronic Filing letter. If you do not enter the code correctly, you will not be able to access the secure areas of the Internet filing web sites.
