Click Coronavirus Disease (COVID-19) to see whether the measures adopted by Revenu Québec apply to the information on this page.

All new employers must register for source deductions in order to obtain their identification number.

You can register by:

  • using either:
    • the Register a New Business service (to register for consumption taxes, source deductions and corporation income tax), or
    • if you are already registered with Revenu Québec, the online service for registering a business with Revenu Québec in My Account for businesses in the Source Deductions and Contributions section);
  • calling our client services; or
  • filing form LM-1-V, Application for Registration.

Even if you have no identification number when you have to remit source deductions and pay your employer contributions to us for the first time, you must make your remittance by the prescribed deadline. In such a case, we will open an account in your name and send you the form to use for the following remittance.

As a new employer, you can make quarterly remittances under certain conditions. Contact us to change your remittance frequency.
