02Entity types

What you can form, and what each one owes.

01

Federal or provincial corporation

Incorporated under the CBCA or a provincial act. Federal incorporation allows operation in any province with extra-provincial registration.

02

Sole proprietor and partnership

Taxed at individual rates with a business number for GST/HST above the threshold.

03

Branch of a foreign corporation

Taxed on Canadian income with a 25 percent branch tax on repatriated profits, reduced by treaty.

03Deadlines

The calendar we run for you.

Every filing, its due date and who it goes to. We track all of them twelve months ahead and remind at 90, 30 and 7 days.

04The provincial layer

The provincial layer.

Canada's complexity is provincial. Ontario and the Atlantic provinces harmonise sales tax into HST; British Columbia, Saskatchewan and Manitoba run separate PSTs with their own registrations; Quebec runs QST and its own income tax administration. A business selling nationally may hold four or five registrations.

05Where we fit

Where we fit.

Canadian subsidiaries of UK, UAE and US groups, and Canadian sellers expanding into US sales tax. We keep the books and GST/HST current and coordinate T2 preparation with a Canadian CPA partner where certification is required.

07Questions
Does a US or UK company selling to Canadians need to register for GST/HST?

Non-resident vendors selling digital products or services, or goods through fulfilment warehouses in Canada, must register once sales exceed CAD 30,000 over four quarters under the simplified or standard regime depending on the supply.

Do you file the T2?

We prepare the accounts and tax computation and file through a Canadian CPA partner, since certain schedules and provincial filings benefit from local certification.
