Canada Tax Calculator (2026) — Add or Reverse Tax
Canada charges a 5% GST/HST, a 26.2% corporate tax rate, and a 33% top personal income tax rate.
How to use this calculator:
- Purchase mode — add GST/HST to a pre-tax price, or reverse a tax-included total to find the pre-tax price and exact tax paid.
- Profit / salary modes — enter an amount to see the corporate tax owed or a ceiling estimate of personal tax at the top marginal rate.
Understanding Canada's Tax System
Canada levies GST/HST at a standard rate of 5%. Its statutory corporate income tax rate is 26.2%, above the 23.58% global average. The top personal income tax rate is 33%.
HST up to 15% in Atlantic provinces; provincial income tax adds up to ~21.8%.

Why Reverse Tax Calculation Matters
Receipts and invoices usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping or cross-border comparisons — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why selecting "Reverse" in the purchase-mode calculator above handles it exactly.
History & Context
Canada's federal Goods and Services Tax (GST) was introduced in 1991 at 7%, later cut to 5% by 2008. Canada layers this federal GST with either a harmonized HST (in Atlantic provinces and Ontario) or separate provincial sales taxes (PST/RST/QST), creating one of the more varied consumption-tax landscapes among major economies.
Because Canada's sales tax structure varies by province — full detail available on this site's dedicated Canada Tax Rates pages — the 5% GST/HST figure shown here for the national comparison understates the true combined rate a shopper in an HST province (up to 15%) would actually pay.
Business Use Case
A business expanding across Canada must determine not just the 5% federal GST but whether each destination province uses HST, a separate PST, or (in Alberta and the territories) no provincial sales tax at all — see this site's Canada Tax Rates section for the full province-by-province breakdown.
Real-World Examples
GST/HST on a purchase
A C$1,000.00 purchase in Canada at 5%:
- Tax: C$1,000.00 × 5% = C$50.00
- Total: C$1,050.00
Corporate tax on profit
C$1,000.00 in company profit in Canada at 26.2%:
- Tax: C$1,000.00 × 26.2% = C$262.00
- After-tax profit: C$738.00
Extracting GST/HST from a receipt total (reverse)
A receipt shows a C$1,499.00 tax-included total in Canada at 5%:
- Pre-tax price: C$1,499.00 ÷ (1 + 5%) = C$1,427.62
- GST/HST: C$1,499.00 − C$1,427.62 = C$71.38
