DT Professional Suite
Program Updates

Please note: Successful installation of the first version of a new tax year requires that your Thomson Reuters account be fully up-to-date. Installation prior to receiving your new licence key will result in loss of access to DT Max including all prior years. To avoid this problem, please ensure that you have received your new licence key by mail or by email and have it in hand before installing.

The downloads are available to licensed users of DT Max only.

If you require assistance with any download, contact Technical Support at 1-800-663-7829 or dt.support@thomsonreuters.com.

To purchase a licence, contact sales at 1 866 653-8629 or DT-sales@thomsonreuters.com. If your username and password do not enable you to sign in, please contact Dr Tax client services at (514) 733-8355 or 1(800) 663-7829.

If you do not have a prior version of DT Max already installed but wish to access previous tax years, you may download the full DT Max package.

The full package contains DT Max T1, T2, T3 and T5013 version for all years as well as the knowledge base in both languages. However, due to its large size, this package should only be downloaded by users who access the Internet using high-speed connections, as using a dial-up connection will be slow and unreliable.
