About Canada GST/HST Calculator

Canada GST/HST Calculator is built to provide fast and practical sales tax estimates for Canadian consumers, freelancers, and small businesses. The project focuses on two outcomes: accurate rate application and clear educational guidance that helps users understand why each tax amount appears.

How We Maintain Accuracy

Provincial and territorial tax combinations are reviewed against official Canada Revenue Agency materials and provincial guidance. When rate changes are announced, we update calculator logic, reference tables, and related content so the tool and articles stay synchronized.

Editorial Policy

Content is written for practical decision support, not legal or accounting advice. Every guide aims to explain tax concepts with concrete examples, clear formulas, and internal links to deeper context. We prioritize direct answers, date visibility, and source transparency to improve both user trust and AI citation quality.

Scope and Limitations

This website does not replace CRA filings, legal interpretation, or professional tax services. Use it for estimation and learning, then confirm official requirements when filing returns, charging tax at scale, or handling complex transactions.

Get in Touch

For corrections, partnership inquiries, or content requests, use the Contact page. If you spot a potential rate mismatch, include the province, scenario, and source so we can verify and publish a revision quickly.
