Canada HST & GST Guide (2026)
Canadian sales tax varies by province. Ontario, Nova Scotia, New Brunswick, Newfoundland, and PEI use a single Harmonized Sales Tax (HST). Alberta, Yukon, Northwest Territories, and Nunavut charge only the 5% federal GST. BC, Saskatchewan, Manitoba, and Quebec combine GST with a provincial sales tax (PST or QST).
The tax rate you charge is based on your client's location, not yours. Serving an Ontario client from BC? Charge 13% HST. Serving a non-resident client abroad? Charge 0% (zero-rated export service).
When you buy goods or services for your business, the GST/HST you paid is recoverable as an ITC — you deduct it from what you owe the CRA. Meal and entertainment expenses are only 50% deductible under CRA rules.
What Is This Calculator?
A Canada HST calculator instantly removes or adds Harmonized Sales Tax (HST) or Goods and Services Tax (GST) from any Canadian price. Canada's tax system is complex because each province applies different rates — Ontario charges 13% HST, Nova Scotia charges 14%, while Alberta has only 5% GST. The reverse formula is simple: Pre-Tax Price = Total Price ÷ (1 + Rate) — but with 13 different province rates, having a tool that handles this automatically saves significant time.
When Should You Use This Tool?
- You received a Canadian receipt and need to isolate the pre-tax amount for expense reporting
- You are a Canadian business owner reconciling GST/HST collected vs. paid on your HST return
- You are pricing a product and need to quote the pre-tax price accurately for different provinces
- You want to compare the true cost of a purchase in a high-tax province (Nova Scotia 14%) vs. a no-PST province (Alberta 5%)
- You are a freelancer billing Canadian clients and need to calculate HST separately on your invoice
