In Canada, we have to report after $30,000. We will be in a similar situation (hopefully) for 2022. Here in Canada, you can start voluntarily reporting after $7,500. The benefit is that I can collect input tax credit for my GST costs on supplies, etc. Still working out the finite details.
Also, we have a single property, and we are not able to split the GST on the rental income between myself and spouse. GST is based on gross rental and service fees, such as Cleaning Fee.
Maybe a quick conversation with a tax planner/accountant could guide you to the best solution.
