GST, PST, and HST Explained

Canadian consumption tax structures vary dynamically by geographic territory. The federal government charges a baseline Goods and Services Tax (GST), while separate provincial authorities layer a Provincial Sales Tax (PST). Multiple forward-thinking jurisdictions fully combine these steps into a singular Harmonized Sales Tax (HST). This engine maps the exact aggregate rate to ensure compliance across all Canadian markets.

Current Tax Rates by Province

Canadian business owners, self-employed creators, remote freelancers invoicing Canadian corporate clients, and active consumers monitoring cross-provincial e-commerce transactions utilize this calculator.

Small Supplier Exemption Rules

1. Input the purchase amount (Canadian Dollars or matching entry currencies). 2. Select your province or territory — the correct GST, PST, or HST rate is applied automatically. 3. Choose whether to add tax to a pre-tax price or extract tax from a tax-included total. 4. Optionally enter your annual taxable revenue to instantly check the CRA's small supplier exemption threshold.

How to Calculate GST/HST Forward and Backward

The calculator separates the federal GST portion from the provincial PST, RST, QST, or HST portion so you can see exactly what's being remitted to Ottawa versus your province. For commercial business logs, the Total Price line represents the exact absolute tax value required to structure customer receipts and remit smoothly to the Canada Revenue Agency (CRA).

💡 Pro Tip: If you maintain a micro-business with under $30,000 CAD in global taxable annual revenues, the CRA classifies you as a 'small supplier' and exempts you from mandatory collection. However, the exact moment your revenues breach that baseline within any single calendar quarter, immediate registration is legally required!
