Private builders often find themselves unprepared to face the tax consequences upon completion of their work. It is
extremly important to obtain a professional advice and do careful tax planning ahead of any project.
Amongst other things to be aware of:
once construction becomes the business carried on for profit, the Primary Residence exemption can not be used and income tax needs
to be paid on the net income that was made,
and
in case of newly constructed or substantially renovated unit, HST should be collected on sale price.
In some cases the CRA has to draw a line between a private construction undertaking and a comercial project, and if Primary
Residence exemption is disallowed, the tax bill may exceed profits by a substantial margin.
Below are some publications that can help to understand the matter:
