Quick overview
Maplr automatically calculates Canadian sales taxes (GST, HST, PST, and QST) based on your settings and the province of supply — so you don’t have to do the math manually.
How tax calculation works
When creating an invoice, Maplr looks at:
- Your account tax settings
- The place of supply province
- The tax rules for that province
It then applies the correct tax automatically.
Tax types supported
Maplr supports all Canadian sales tax systems:
- GST (5%) — federal tax
- HST — combined federal + provincial tax
- PST — separate provincial tax
- QST — Quebec’s provincial tax
How taxes are applied by province
Depending on the selected province:
HST provinces
Example: Ontario (13%)
- A single tax is applied
- Includes both federal and provincial portions
GST only provinces
Example: Alberta (5%)
- Only GST is applied
- No provincial tax
GST + PST provinces
Example: British Columbia
- GST and PST are calculated separately
- Both appear on the invoice
GST + QST (Quebec)
- GST and QST are applied
- QST follows Quebec-specific rules
Automatic calculation on invoices
When you add line items:
- Enter rate and quantity
- Maplr calculates subtotal
- Tax is applied automatically based on settings
- Total is updated instantly
👉 You should never manually add tax to your rates.
Tax handling options
When creating an invoice, you can choose:
- Use account default → uses your saved tax settings
- Apply tax automatically → enables tax calculation
- No tax → disables tax for that invoice
Example (Ontario)

- HST (13%): $130
- Total: $1,130
