Bright-line Test NZ: The 2-Year Rule Explained (2026 Update)

The Bright-line Test, or "Bright-line Rule", applies to the sale of residential property in New Zealand. If the bright-line test applies, the seller's net profit is generally taxable as income at the seller's applicable income tax rate. The seller must complete an IR833 Bright-line property sale information form and include their share of the net profit in their income tax return.

For most land transfers, each seller must provide tax information in a Land Transfer Tax Statement. That information is supplied by LINZ to Inland Revenue.

The good news: the bright-line period is now just 2 years

The bright-line rules were significantly simplified from 1 July 2024. For any residential property sold on or after 1 July 2024, the bright-line period is now 2 years, and this applies to all residential property, no matter when you bought it.

This was a major rollback from the previous rules. Before 1 July 2024, some properties carried a 10-year bright-line period (or 5 years for qualifying new builds), and others a 5-year or 2-year period depending on when they were acquired. Those old timeframes no longer apply to current sales. If you sell today, the only question is whether you are selling within 2 years of your bright-line start date (generally the date the title was transferred to you at settlement).

A quick example: if you bought an existing, non-new-build rental property in 2022, the former rules would generally have imposed a 10-year bright-line period. Under the current rules, its 2-year bright-line period ended on the second anniversary of its bright-line start date in 2024, so a sale today would fall outside the bright-line test altogether.

One trap to watch: the bright-line "end date" is generally the date you enter into the agreement to sell, not the settlement date. So if you sign a sale and purchase agreement 23 months after settling your purchase, you are still inside the 2-year window even if settlement of your sale happens later.

Exceptions to the bright-line rule

There are some exceptions to the bright-line rule:

• The sale of business premises
• The sale of farmland
• Selling your main home
• A property you inherit under a deceased estate
• Certain transfers where "rollover relief" applies (see below)

Residential property used predominantly as business premises is excluded from the bright-line test. Farmland is also excluded where it is worked in a farming or agricultural business by the owner, or is capable of being worked as a farming or agricultural business because of its area and nature. A lifestyle block will not necessarily qualify. Mixed-use properties, such as a family home on the farm or a property where you both live and run your business, require careful analysis, so you should always get advice before selling.

The main home exclusion: not as simple as it sounds

Generally, the bright-line rule does not apply to the sale of your main home. But the exclusion is not automatic just because you lived in the property at some point. For property sold on or after 1 July 2024, the main home exclusion applies only if:

• you used more than 50% of the property's area as your main home (including the yard, gardens and garage); and
• you used the property as your main home for more than 50% of the bright-line period.

The rules also include some flexibility: a continuous period of up to 12 months during which the property was not used as your main home (for example, while renovating or travelling) may nevertheless be treated as main-home use where it falls immediately before or after a period of actual main-home use. If you bought bare land and built your home on it, the construction period (including the design phase) may also be ignored when working out whether you meet the 50% use test, with the precise period depending on the circumstances.

There are two important limitations. The exclusion is not available where you have a regular pattern of buying and selling, or building and selling, main homes. It is also unavailable if you have already used the main-home exclusion twice during the 2 years immediately before the sale.

Special rules apply where your main home is held in a family trust. As always, it pays to take advice before making any assumptions, and before you list your property for sale.

Rollover relief: transfers within the family and to trusts

From 1 July 2024, "rollover relief" was significantly expanded. Rollover relief means that certain transfers of property don't trigger the bright-line test at the time of transfer. Instead, the new owner effectively "steps into the shoes" of the original owner, inheriting their bright-line start date (and, in some cases, their main home usage).

Rollover relief is now available for transfers between associated persons, which can include close relatives, trustees and settlors of family trusts, partnerships and their partners, and look-through companies and their owners. Two key conditions to be aware of:

• the transferor and transferee generally must have been associated for at least 2 years before the transfer; and
• under the associated-person rules, rollover relief can only be claimed for the same property once in any 2-year period beginning on the date of the first qualifying transfer.

This can be a valuable tool when restructuring property ownership. But "associated persons" is a highly technical concept, and not every transfer to a family trust will automatically qualify, and specific conditions apply to trusts and their beneficiaries. The rules are technical, and any subsequent sale can still be caught, so get advice before signing anything.

Inherited property and relationship property

The bright-line test does not apply to a transfer from a deceased person to the executor or administrator of their estate, a transfer from the estate to a beneficiary, or a subsequent sale by the beneficiary of the inherited property. However, if the beneficiary separately purchases another person's share of the property, that purchased share may be subject to the bright-line test.

Rollover relief also applies to qualifying transfers of relationship property between spouses, civil union partners or de facto partners under the Property (Relationships) Act 1976. The recipient generally inherits the property's original bright-line start date, so a subsequent sale may still be taxable if it occurs within the original 2-year period.

Other tax rules may still apply

Even if you sell outside the 2-year bright-line period, that does not automatically make the sale tax-free. Other land sale rules may still tax the sale, including where:

• you bought the property with the intention of selling it;
• you have a pattern of buying and selling (or building and selling) your properties; or
• you are associated with, or in the business of, property dealing, development or building, and the property was bought for that business.

The bright-line test is only one part of the wider property tax picture.

Residential Land Withholding Tax (RLWT)

RLWT may be deducted where the seller is an "offshore RLWT person" and the sale is subject to the bright-line test, unless the seller holds a valid certificate of exemption. For a New Zealand company, this can include circumstances where more than 25% of its directors are offshore RLWT persons or more than 25% of its shareholder decision-making rights are held or controlled by offshore RLWT persons. Separate and detailed tests apply to trusts, estates, look-through companies and partnerships.

Where RLWT applies, it is generally deducted from the sale proceeds at settlement by the seller's conveyancer and paid to Inland Revenue.

Get the right advice!

While the move to a single 2-year bright-line period has simplified things considerably, the details still matter, particularly around the main home exclusion, trusts, rollover relief, and the other land sale rules that sit alongside the bright-line test. It is important that you get the right advice before listing your property for sale. Bright-line is a tax issue, so your accountant or tax advisor is the right person to confirm whether tax will apply to your sale. Our team can then take care of the legal side of your property transaction, working alongside your accountant to make sure there are no surprises at settlement.
