Self-assessment is the cornerstone of the Québec tax system. This means that all taxpayers must calculate their fair share of income tax based on information related to their income, deductions and tax credits and pay any amounts they owe. We are therefore counting on everyone's full cooperation to collect the amounts that the Québec government needs to function.

In return, we recognize that taxpayers are entitled to plan their affairs so that they only pay what is legally due.

One mission. Concrete actions.
