Depending on the nature of your business activities, other taxes and measures may also apply to you. For more information, read “Registering for other tax files” below.

Registering for other tax files

If you do business in certain fields of activity, you may have obligations regarding the following taxes:

Corporation income tax 

Because the Québec tax system is based on self-assessment, you must, as a taxpayer and agent, report your income, and calculate and remit your income tax and consumption taxes. A corporation that has an establishment in Québec must be registered for corporation income tax in order to fulfill its obligations.

Registering for source deductions

When you hire an employee for the first time, you must register for source deductions to receive an identification number.
