The bright-line test has been changed often enough that a great deal of outdated guidance is still circulating, some of it referring to ten-year and five-year periods that no longer apply. The current position is considerably simpler than the recent history suggests.
The current rule: two years
For residential property sold on or after 1 July 2024, the bright-line period is two years. This applies regardless of when the property was acquired — a property bought during the period when a ten-year test applied is now measured against the two-year rule if sold today.
The earlier distinction between new builds and existing properties has gone. One period now applies to residential land generally.
How the period is measured
The start and end points are not the dates most people assume.
The clock generally starts on the date the title is transferred to you — settlement, when the transfer is registered. It generally ends on the date you enter into a binding agreement to sell, not the date that sale settles.
That asymmetry has a practical consequence. If you sign a sale and purchase agreement one day before the two years is up, you are within the bright-line period even though settlement occurs months later. Where a sale is close to the boundary, the date of the agreement is the date that counts, and it is worth checking before signing rather than after.
Different rules apply to land acquired off the plan and in some subdivision situations, so those need to be checked individually.
What happens if you are caught
If residential land is sold within the bright-line period, the gain is taxable as income. It is added to your other income and taxed at your marginal rate — there is no separate concessionary capital gains rate in New Zealand.
The taxable amount is the sale price less the cost of the property and certain allowable costs, which can include acquisition costs, some improvement costs and selling costs. Where the sale produces a loss, the loss is generally ring-fenced and can only offset other taxable land sale gains, not income generally.
The main home exclusion
The most important exclusion is for the main home. Where the land has been used predominantly, for most of the time you owned it, as your main home, the bright-line test generally does not apply.
Two things trip people up. The test is about predominant use for most of the ownership period, not simply whether it was your home when you sold. And where you have more than one home, only one can be the main home — determined by which you have the greatest connection with.
Property owned by a trust has its own rules, and the main home exclusion applies differently. That is worth advice rather than assumption.
Inherited property and relationship property
Property acquired through inheritance is generally excluded from the bright-line test on later sale. Transfers on the settlement of relationship property generally roll over rather than triggering the test, with the recipient inheriting the original acquisition date — which means the clock does not restart.
The bigger point: bright-line is not the only rule
This is the part most commonly missed. The bright-line test is a backstop, not the whole of the law. Other land taxing provisions apply regardless of how long you have owned a property.
If you acquired land with a purpose or intention of resale, the gain is taxable under the intention test whether you held it for two years or twenty. Provisions also apply to dealers, developers and builders and to associated persons, and to land where a change in use or rezoning produces a gain.
Selling outside the two-year window is therefore not automatic confirmation that a gain is untaxed. It means one specific rule does not catch you.
Practical steps
- Check the actual dates — title registration in, binding agreement out — before committing to a sale near the boundary.
- Keep records of acquisition costs, improvements and selling costs. They reduce a taxable gain and are difficult to reconstruct later.
- If the property was ever rented, used in business, or owned by a trust, get advice rather than relying on the main home exclusion.
- Be honest about intention at acquisition. The intention test is applied to the evidence, and contemporaneous documents matter.
Inland Revenue publishes current guidance on the bright-line test and the wider land rules free at ird.govt.nz, and it is updated when the rules change — which, on recent history, is worth checking rather than assuming.
