How VAT, GST, HST, PST, and QST Fit Reverse Tax
Consumption-tax reverse calculation removes tax from a gross price by matching the tax label to the correct structure. VAT and GST often use one rate. HST is a blended Canadian rate. PST and QST can appear beside GST, which means the tax lines may need to be separated before calculation.
VAT
Usually reversed from a gross VAT-inclusive price into net price and VAT included.
GST/HST
GST may stand alone, while HST combines federal and provincial tax in participating provinces.
PST/QST
Often requires separate treatment beside GST rather than one generic combined rate.
Match the Tax Label First
- Read the tax label on the receipt or invoice before choosing a page.
- Confirm whether the tax is blended into one line or split across multiple lines.
- Use the tax-specific guide when the jurisdiction changes the rate or base.
Consumption-Tax Mixups
- Using VAT language for Canadian GST/HST/PST/QST receipts.
- Combining separate GST and PST/QST lines without checking the bases.
- Ignoring reduced, zero-rated, or exempt supplies.
