Tax Registration in Canada
A CRA Business Number with the program accounts the business actually needs — corporation income tax (RC), GST/HST (RT) and payroll (RP). GST/HST registration is threshold-triggered: you must register once you are no longer a 'small supplier', which means taxable revenues exceeding CAD 30,000 over four consecutive calendar quarters, or exceeding CAD 30,000 in a single quarter (in which case small-supplier status ends immediately); registration must be done within 29 days of the effective date, and voluntary registration below the threshold is allowed. GST is 5% federally; in the HST provinces (ON, NS, NB, NL, PE) a single Harmonized Sales Tax combines the federal and provincial components; Quebec runs QST through Revenu Québec, BC, SK and MB run a separate PST, and Alberta has no provincial sales tax.

Cost breakdown
Our fee and the government’s are always separate lines. Government fees are passed through at exactly what the authority charges — we add nothing to them.
| CRA Business Number and program-account registrationThe CRA publishes no registration fee amount on the pages read for this file, so this is left unpriced rather than shown as a verified zero. The VERIFIED content here is the obligation, not a price: the GST/HST small-supplier threshold is CAD 30,000 of taxable revenue over four consecutive calendar quarters, and registration is due within 29 days of the effective registration date. | Confirmed before payment |
| Provincial sales-tax registration (QST, PST)Quebec (QST, via Revenu Québec) and BC / SK / MB (PST) administer their own sales taxes; Alberta has none. Neither the fees nor the registration rules were read from each province's own source, so this is scoped at quote. | Confirmed before payment |
