Tax Data Delivery - Error message ERR.090

Dear Cantax client:

A technical problem was identified in Cantax T1, which currently prevents you from using the CRA’s Tax Data Delivery (TDD) service. As a result, a new version of Cantax T1 (v.112) will be released tomorrow afternoon, i.e. March 10, 2015.

The sole purpose of this version is to correct the problem with the TDD service. Therefore, if you do not use the TDD service, you are not required to install this update. This version will only be available for download. No CD-ROMs will be shipped.

Please note that tax information is still available on the CRA’s Represent a Client Web site and can be accessed at all time.

We thank you for your understanding.

The Cantax T1 Team
