Overview

The Tax Settings page displays all tax rates configured for your organization. Each rate has a name, abbreviation, and percentage. Rates can be activated, archived, or searched. The default tax rate (used when creating new invoices or estimates) is set in Business Settings and pulls from this list.

- Enter a Name — a descriptive label such as "HST – Ontario" or "GST".
- Enter an Abbreviation — a short code like "HST" or "GST" that will display on invoices and tables.

The new rate immediately becomes available as an option on invoices, estimates, and other financial records.
Canadian tax configuration (HST / GST / PST)
Appello supports the tax structures used across Canadian provinces:
| Tax Type | Description | Example |
|---|---|---|
| HST | Harmonized Sales Tax — a combined federal/provincial rate used in ON, NB, NS, NL, PE. | 13% (Ontario) |
| GST | Goods and Services Tax — the federal component, used in provinces without HST. | 5% |
| PST | Provincial Sales Tax — the provincial component, used alongside GST in BC, SK, MB, QC. | 7% (BC) |
| QST | Quebec Sales Tax — Quebec's provincial tax, applied alongside GST. | 9.975% |
| No Tax | Zero-rate entry for exempt items or out-of-province work. | 0% |
To handle combined GST + PST scenarios, create separate tax rate entries for each component or a single combined entry depending on your invoicing requirements.
Applying tax rates to invoices and estimates
| Context | How tax is applied |
|---|---|
| Creating an Invoice | Select the applicable tax rate from the dropdown on the invoice form. The tax amount is calculated automatically based on the subtotal. |
| Creating an Estimate | Select the tax rate when adding line items. The estimate total reflects the tax calculation. |
| Default Tax Rate | Set in Business Settings, the default rate is pre-selected on new invoices and estimates. Users can override it per document. |
| Line-Item Tax | Some configurations allow different tax rates per line item for mixed-tax scenarios. |
| Expenses | When recording expenses, select the applicable tax rate to track input tax credits (ITCs). |
Applying tax rates to expenses
When entering expenses in Appello, selecting the correct tax rate ensures:
- Accurate tracking of input tax credits (ITCs) for GST/HST recovery.
- Proper categorization when expenses sync to QuickBooks or your accounting system.
- Consistent reporting in financial summaries and tax filings.
