Do I need a business license (a business number) to write off expenses, such as rentals, mileage, etc.) on my income tax for freelance work? Do I just fill out the Schedule C? Or do I need the business license to do this?
Schedule C is for American returns. If you are filling out a Canadian return, complete form T2125 for business income and expenses. You do not require a business number if you are operating under your own name.
