T4 Internet Filing
A fast and convenient alternative to magnetic media filing your clients' T4 slips. The system supports T4 filing for companies with up to 449 employee slips.

What You Need

• A magnetic media transmitter number. If you don't have a transmitter number, call 1-800-665-5164 to obtain one.
• A Web Access Code (WAC) for each employer for whom you file slips.
  The WAC is printed above the Business Number (BN) on the personalized T4 Summary that the business receives by mail.
• You can also "look up" a WAC by calling the T4 Internet filing help desk at 1-877-322-7849.

How to Internet File T4 Slips

1 Open the file containing T4 slips ready to file.
2 Click on EFILE > Internet file T4s.

• If the build is successful
  - ProFile saves the XML file for this return (same file name except the extension) in the default directory for your FX files.
  - The path to that directory appears under Options > Environment > File.
  - ProFile will launch its own web browser where you can continue the process.
• If the build is NOT successful
  - An error message tells you what requires correction. 

Note: The process for T4 Internet filing is not automatic.

3 Enter the WAC for the business and browse to your FX directory to attach the XML file you have built. 
4 Complete each step in the web transmission process.

• Note the confirmation number on the final page before closing the browser.
