To calculate your gross yearly salary (your total earnings over the course of a year) and subtract your taxes owed which depends on the tax bracket that you fall into.

The federal government has a principal residence exemption. This means that if you sell your house, you do not have to pay tax from any gain you get from the sale of your house. This only applies if the property was your principal residence for all the years you owned it. In Ontario, there is the Land Transfer Tax, but this is not related to your yearly return.

The tax calculation in Ontario is simple. All you have to do is take your total earnings, add the exempted amounts and then deduct the tax deductions and credits that you are eligible for. Once all these steps are followed, you can find out exactly how much tax you need to pay.
