Dedicated telephone service for income tax service providers: How to register
The Income Tax Rulings Directorate’s Dedicated Telephone Service (DTS) offers free technical help for small and medium income tax service providers. Experienced CRA officers are available by telephone to help you find the information you need to interpret the provisions of the Income Tax Act.
In order to provide you with the most accurate and relevant information possible, DTS officers will not provide an immediate response to your question over the telephone. After reviewing your tax issue, the officers will carefully consider your question and send you helpful information and guidance by email. They will generally get back to you within three business days, depending on the complexity of the tax issue. Officers are ready to assist you in both English and French.
DTS officers do not have access to taxpayers’ accounts.
Eligibility
To be eligible for this service, you must be a small or medium income tax service provider who prepares, or assists in the preparation of, Canadian income tax returns on behalf of individuals or businesses.
An income tax service provider is a firm, organization, or tax practitioner, such as an accountant, bookkeeper or lawyer, that provides audit, accounting, tax, and/or other advisory services.
Specialized tax professionals representing large firms – those with more than 50 partners – are not eligible for this service. These practitioners should continue to use the CRA's Income Tax Rulings Directorate's advance income tax rulings or technical interpretations service to address their interpretive income tax issues.
Register for the DTS
