How Canada HST / GST works
Canada uses federal GST (5%) plus provincial sales tax or a combined HST in participating provinces (e.g. 13% or 15% HST). Rates vary by province — Ontario HST is commonly 13%.
This calculator uses a single combined percentage. Enter 5 for GST-only, 13 for typical Ontario HST, or your exact combined rate. Example at 13%: CA$100 net → CA$13 tax → CA$113 gross.
After calculating, create a CAD invoice with the correct tax label in InvoBuzz.
Reverse charge & inclusive prices
Canada generally does not use EU reverse charge, but specific imported taxable supply rules may apply. Confirm with the CRA for cross-border services.
Invoice requirements
Canadian invoices should show business name, invoice number/date, customer details, description, and GST/HST registration number when required, with tax amounts clearly stated.
