Whether you are a business calculating how much GST/HST to remit or a consumer trying to understand the tax-inclusive price, this tool handles every Canadian rate. The federal GST rate is 5%. Provinces that have harmonized with the federal system charge a combined HST: Ontario charges 13%, New Brunswick, Nova Scotia, Newfoundland and Labrador, and PEI charge 15%. British Columbia, Saskatchewan, and Manitoba levy a separate provincial sales tax (PST) in addition to federal GST. Quebec has its own system, the QST, at 9.975% on top of the 5% GST. Enter an amount, choose whether it is tax-inclusive or exclusive, select your province, and instantly see the tax portion and the base or total price. If your business revenue exceeds $30,000 in four consecutive calendar quarters, you must register for GST/HST with CRA.
