Here are some instructions for T4 Electronic filing we discovered after several calls with our clients and to people at Canada Revenue Agency…
In Sage 300 ERP:
1) Be sure that all employees have the PROVINCE in the PROVINCE field on their general tab (Payroll Employees, general), or it will not generate the file
2) Be sure that you have the province in both the Employer Info and Transmitter Info 1 Screens and you also need to have the contact name, phone # and email where it is requested.
3) You need to enter something in the SIN of 1st Proprietor field or it will not process the file. You can use zeroes.
4) Fill the Transmitter Info II screen out as per above … the MM number was something CRA was testing but are no longer using, so you just fill the rest of the field with zeroes. The Submission reference ID is one you decide on.
You decide on the location of the file by browsing. If you have more than one RPP # you can include the info in the file, eg: T4EFILERP0001.
5) When you get to the CRA site, you select T4/T5 by Internet then Filing a T4 Information Return, then Internet File Transfer (XML), FILE NOW, Enter Secure site.
6) After clicking on the I agree button, you will see a screen where you enter your RPP number or MM #. Since the MM# does not exist, enter first your RPP # then further down there is a spot to enter the Web Access Code you were given by CRA.
7) Click the continue to next step button at the bottom of the screen and then select the file you saved in # 4 and upload it.
8) If the file was transmitted successfully you will receive a display telling you that the upload was successful. This will confirm the number of T4 slips, date and time and will give you a confirmation number. Be sure to print this page for future reference.
Repeat the above for each RPP # you have.
