Starting a Business in Canada - Quick Facts
Just the "Coles Notes" for Starting a Self Employment Business in Canada
Start with the basics
Most freelancers start off as a “Sole Proprietorship” which is a non-incorporated business (also referred to as “self employed”). This is not something you register for, it’s just how you are taxed. If you are considering starting a Corporation, you should connect with an accountant to discuss that further.
GST/HST and registration
You do not have to register your business with the Federal Government until there is a reason to do so. You do not have to register with the Canada Revenue Agency (CRA) and get a Federal Business Number unless one of these three things occur: You want/need to start charging GST/HST, you hire an employee, or you incorporate the business.
Keep clean records from the start
It will help IMMENSLY to have a bank account and credit card that you ONLY use for business transactions. It doesn’t have to be a business bank account, it can be a normal account that you simply only use for business deposits and expenses.
