Cantax T2/T2Plus
Corporation Internet Filing (CIF) with prior versions of Cantax T2

Dear Cantax T2 Customer:

Effective October 2015, in accordance with the latest CRA requirements, you will have to make sure that the program is installed on a recent operating system to electronically transmit federal tax returns (T2) with Cantax T2/T2Plus 14.2.3xx.126 or prior versions. The following operating systems will no longer allow you to transmit electronically:

  • Windows XP;
  • Windows Vista;
  • Windows Server 2003;
  • Windows Server 2008.

We are sending this notice now so you have time to replace or upgrade any of your operating systems in order to be able to electronically file federal tax returns with prior versions of Cantax T2/T2Plus.

With Cantax T2/T2Plus 15.1.3xx.100 and future versions, you will be able to file federal tax returns using CIF on the above mentioned operating systems, as long as they are supported by Cantax.

As mentioned in prior communications and in compliance with Microsoft’s support policy, Cantax will no longer be supported on Windows XP, Windows Server 2003 and Terminal Server 2003 as of July 2015.

While this extension will provide you with more time to update your operating systems, it is in your best interest to update as soon as possible. You will then avoid any future security or compatibility issues and continue to receive the high level of support you expect from Wolters Kluwer.

If you have any questions, support is only a phone call away at 1-888-829-7848.
