The tax amounts above come from the price and province you select—not a third-party feed. We apply the combined sales tax rate for that province or territory: federal GST (5% everywhere), or a single HST rate where provinces have harmonized, or GST plus provincial PST/QST/RST where they are charged separately. Below are the formulas for both modes (add tax and remove tax), the order we follow, and worked examples you can check by hand.
Formulas
| Line | Formula |
|---|---|
| Add tax — tax amount | Tax = price before tax × combined rate |
| Add tax — total price | Price after tax = price before tax + tax |
| Remove tax — price before tax | Price before tax = price including tax ÷ (1 + combined rate) |
| Remove tax — tax extracted | Tax = price including tax − price before tax |
| Effective tax as % of pre-tax price | Tax ÷ price before tax × 100 |
| Tax as % of total price | Tax ÷ price including tax × 100 |
Order of operations
Look up the combined rate for your province
Combined rate = federal GST + provincial portion (or HST total)
Each province or territory has a fixed combined rate in our table—for example 13% HST in Ontario, 5% GST only in Alberta, or 5% GST + 9.975% QST in Quebec. Nova Scotia uses 14% HST (reduced from 15% on April 1, 2025).
Choose add tax or remove tax
Add: start with pre-tax price · Remove: start with total including tax
Use Add Tax when you know the shelf or invoice subtotal and want the customer total. Use Remove Tax when you have a receipt total and need to back out the pre-tax amount—for example for expense reporting or margin calculations.
Add tax (forward calculation)
Tax = amount × rate · Total = amount + tax
Multiply the pre-tax price by the province's combined rate. The result is the tax; add it to the original price for the total including tax.
Remove tax (reverse calculation)
Pre-tax = total ÷ (1 + rate) · Tax = total − pre-tax
Divide the tax-inclusive price by (1 + rate) to get the pre-tax amount. The difference between the total and pre-tax price is the tax portion.
Worked example
$100.00 pre-tax in Manitoba (5% GST + 7% RST)
Add tax
$100.00 × 12% = $12.00 tax → total $112.00
Remove tax (reverse check)
$112.00 ÷ (1 + 12%) = $100.00 pre-tax · tax extracted $12.00

What we do not model on this page
We apply a single combined rate to the full price you enter. We do not model zero-rated or exempt goods (basic groceries, prescription drugs, many health services), place-of-supply rules for interprovincial or cross-border sales, GST/HST registration thresholds, input tax credits (ITCs), compound tax stacking beyond the published combined rate, or historical rate changes within a year. Quebec QST is calculated on the same pre-tax base as GST (aligned since 2013), which matches how our combined rate works. For income tax and take-home pay, use our Canada tax calculator.
