What is a Compound Tax? A compound tax combines the federal sales tax (GST) and the provincial sales tax (PST) into a single harmonized sales tax (HST). This applies only in certain Canadian provinces.
Important for professionals in Quebec: In Quebec, GST and QST must be applied separately. Do not enable the compound tax option, as this may cause calculation errors on your invoices.Check your tax settings
Before issuing invoices, make sure your tax settings follow the tax regulations of your province. Incorrect settings could affect the accuracy of your billing.

Once your taxes are set up, they will be applied to:
- Taxable services billed to clients.
- Expenses and revenues where taxes apply.
