Quebec Tax Calculators is a free resource built for Quebec residents who want accurate, up-to-date financial estimates without signing up or paying anything. If you have a question about how a calculator works, spot an error in a rate or bracket, or want to suggest an improvement, we want to hear from you.
Please include as much detail as possible when reporting a rate discrepancy — for example, the calculator name, the input values you used, and the official source you believe we should be using. We verify all corrections against government publications before updating the site.
What to Include in Your Message
Que mettre dans votre message
Rate or number correction: Tell us the calculator name, the specific figure that looks wrong, and the official source (e.g., a CRA page, Revenu Québec publication, or municipal bylaw). We aim to update verified corrections within a few days.
Feature request or bug report: Describe what you were trying to calculate, what you expected to see, and what you actually saw. A screenshot is helpful but not required.
General question: If you're unsure whether a calculator applies to your situation, we're happy to clarify its scope. We can't provide personal tax or financial advice, but we can explain how the tool works and what assumptions it makes.
Media or partnership inquiry: If you're writing about Quebec personal finance and want to reference or embed one of our calculators, feel free to reach out.
