Payroll - Submit T4s electronically

If filing paper copies of your employees’ T4s and Summary page, search for the appropriate CRA mailing address for your area.

As of January 2024, Issuers who file 6 or more T4 slips of the same type must use the Online filing method.

Once your T4 xml file has been downloaded and saved on your computer (see instructions on how to generate T4s here), you can file electronically through the Canada Revenue website.

Click on File online in AgExpert and the CRA webpage will open. 

Follow the instructions on the CRA portal to file your T4 return online.

Read carefully the disclaimer and terms of use and make sure to have the information requested under the online checklist, then click I agree.

Fill out your payroll account number and Web access code and Sign in.

If you can’t remember your access code or simply don’t have it yet, you can retrieve it by either clicking Forgot your web access code or go to the online we access code page to register. Make sure to have information about your payroll account handy.

Once signed into the CRA portal, click Browse to upload your xml file

When the file is uploaded and no error message is received, you can then submit it to CRA.
