Register for the Dedicated Telephone Service

The Canada Revenue Agency's (CRA) Dedicated Telephone Service (DTS) for income tax service providers helps you find the information you need to interpret the provisions of the Income Tax Act.

The DTS is available to small and medium income tax service providers who prepare, or assist in the preparation of, Canadian income tax returns on behalf of individuals or businesses. Specialized tax professionals who represent large firms (those with more than 50 partners) are not eligible for this service.
