You must obtain a Web Access Code (WAC) to submit your corporation's return using the CRA's Corporation Internet Filing system. When contacting the CRA to obtain a Web Access Code, the CRA will ask you to provide:
Your business number
Your corporation's fiscal year
Obtain your Web Access Code
Call the CRA at 1-800-959-2803. The CRA will issue an 8-digit Web Access Code over the phone. This typically takes 5 to 10 minutes. You'll enter your Web Access Code in the CRA's Corporation Internet Filing website when filing your return.
