Do I pay tax when I sell my house in New Zealand?

The rules that can make a sale taxable

Inland Revenue treats the taxation of property sales as a list of situations rather than one general regime. The main ones are these.

• An intention to resell at the time you bought.
• A regular pattern of buying and selling.
• Being a dealer, developer or builder, or associated with one.
• The bright line test.

The bright line test in short

Residential property sold on or after 1 July 2024 is caught by the test if the sale falls within two years of acquiring it. There is a main home exclusion, it has conditions attached to it, and property used predominantly as business premises, and farmland, sit outside the test altogether. The detail, including both halves of the exclusion and the situations where it is not available, is on what is the bright line test when selling.

Intention is judged at the time you bought

The intention rule looks at your purpose when you acquired the property, not at what you decided later. If one of your purposes at that point was to sell it again, the profit can be taxable however long you held it and whatever you used it for in the meantime.

Intention is worked out from the evidence rather than from what is said afterwards: how the purchase was financed, what was said to the lender, and how long you have held the other properties you have owned.

A pattern, a trade, or a connection to one

Repetition matters on its own. A regular pattern of buying and selling can make sales taxable even where each one looked ordinary at the time, and a regular pattern of building and selling does the same.

There are also rules for people in the property trade: dealers in land, developers and builders. Those rules can reach a sale made by a person associated with one of them, which is the part people do not see coming. Being related to, or in business with, a builder or a developer can change how a property you sell yourself is treated.

No capital gains tax is not the same as always tax free

This is the point that catches people. The absence of a general capital gains tax does not mean the family home is automatically outside the tax rules. A sale can be taxable because of why you bought, because of a pattern of sales, because of who you are associated with, or because of the bright line test, and those rules sit alongside each other rather than cancelling one another out.

What to check before you sell

Work out when you acquired the property, how long you have owned it, how it has been used, and how many properties you have sold recently. If any of those is close to a line, get it looked at before you sign, not after settlement, because the answer can change whether the sale is worth doing on that timing at all.
