CB 16A: Main home exclusion for disposal within 2 years
or “No tax on selling your main home within two years, with some exceptions”

You could also call this:

“Exemption from tax when selling your main home”

You don’t have to pay tax on the sale of your house if you live in it. This applies to the land your house is on and some extra land around it. Here’s how it works:

If you buy a house or build one, and you or your family live in it as your main home, you don’t have to pay tax when you sell it. This also applies if you’re a trustee and a beneficiary of the trust lives in the house.

The tax-free part includes the land your house is on. It also includes extra land up to 4,500 square metres. If you need more than 4,500 square metres to use and enjoy your house properly, that extra land is also tax-free.

But there’s a catch. If you keep buying and selling houses that you live in, you might have to pay tax. This is to stop people from using this rule to avoid paying tax when they’re really in the business of buying and selling houses.

When deciding if you’re buying and selling houses too often, the law looks at you and people connected to you as a group. This includes people who live with you in these houses, and companies or trusts that you control.

Sections CB 6 to CB 11 explain more about when you might have to pay tax on selling land or property.
