T4 Web forms

All you need to use T4 Web forms is a compatible browser to complete, print, and submit a T4 information return. For information about T4 Web forms, visit our T4 Web forms Web page.

T4 or T1204 Desktop application

To be able to use Information Returns Electronic Filing, you have to download and install this year's T4 or T1204 Desktop application (version 6.1). Applications from previous years are not compatible with this year's. For information about this year's Desktop applications, visit our Desktop application Web page.

Internet file transfer (XML):

As of January 2006, the Internet File Transfer (XML) will be available for the following information returns: Originals and amended - T1204, T4, T4A, T4A-NR, T4RIF, and T4RSP; Originals only -T4E. You can also file multiple returns within a single submission (maximum 610 kb). Clients will need a payroll Business Number (RP) and a Web Access Code (WAC) when they file these returns with the CRA.

Note: Currently, our Web Access Code (WAC) authentication system only recognizes Business Number (BN) accounts with an RP extension for the XML filing option. Unfortunately, the functionality to accept account numbers other than a BN will only be available for the 2007 filing season. However, clients who already have a Payroll Number (RP), and an associated WAC to file their T4 returns, may also file original NR4, T3, T5, T5007, T5008, and T5018 returns, as well as amended NR4, T3, T5, and T5008 returns using the same Payroll Number and WAC.
