Self employed as IT consultant and as massage therapist: Do I need 2 HST numbers?
Given your clarifying points, it sounds like you are running both businesses as one combined business. As such, you should be able to get just a single HST number and use that. However, let me please urge you to contact a professional accountant and possibly a lawyer, as it is very unusual to be performing these services without a business license, and you may be exposing yourself to civil penalties and placing your personal assets (e.g. your house) at risk. Additionally, it may be beneficial for you to run these as businesses as you can likely write off (more of) your expenses.
