Old Rules: When you sell your principal residence or when you are considered to have sold it, usually you do not have to report the sale on your income tax and benefit return and you do not have to pay tax on any gain from the sale. This is the case if you are eligible for the full income tax exemption (principal residence exemption) because the property was your principal residence for every year you owned it.

New Rules: Starting with the 2016 tax year, generally due by late April 2017, you will be required to report basic information (date of acquisition, proceeds of disposition and description of the property) on your income tax and benefit return when you sell your principal residence to claim the full principal residence exemption.
