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.

- 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
