Common questions
Which provinces does it cover?
All of them, with presets for the harmonized and GST-only provinces, plus a custom rate for provinces where PST or QST is billed separately.
Can it remove tax from a total?
Yes — switch to Extract mode: the net price is total ÷ (1 + rate), and the tax is the remainder.
Are these the official rates?
The 2026 rates, yes — but the result is an estimate. CRA is authoritative for filing.
