Sell into Canada and leave sales tax to us.
Zamp runs GST, HST, PST, and QST end to end. Registrations, calculations, filings, and remittance across all 13 provinces and territories. Canada is the first market where we manage the entire compliance lifecycle, not just the calculation.
Trusted by 1,200+ finance and accounting teams.
One country, four tax systems, thirteen jurisdictions.
Canada layers a federal tax (GST) on top of provincial ones (HST, PST, QST), and place-of-supply rules decide which applies to each sale. Register late, charge the wrong rate, or file in the wrong place and the cleanup lands on your finance team.
Most companies end up with two options that both create work:
Build and maintain internally
Manual rate tables, separate provincial accounts, and growing audit exposure.
Patchwork of local accountants and tools
Different handling per province, fragmented data, and no single source of truth.
