The Bright-Line Test in 2026: What NZ Property Owners Owe | NZ Legal

If you last looked at the bright-line test a few years ago, what you remember is almost certainly wrong. The rule that once locked property owners in for ten years now runs for two. The main home exclusion changed at the same time, and it is now more generous than most people expect. Between them, those two changes have moved a large number of sales out of the tax net, and caught out just as many people who sold on the wrong advice.

This guide sets out where the bright-line test stands in 2026: how long the period actually is, the two dates that decide whether you are inside it, who is exempt, what you pay if you are caught, and the withholding tax that applies if you are selling from overseas.

What the bright-line test is

The bright-line test is an income tax rule. If you sell residential land within a set period of buying it, the profit is taxed as income. New Zealand has no general capital gains tax, so the bright-line test is the closest thing to one for residential property, and it applies whether or not you ever intended to make a quick gain.

It is administered by Inland Revenue, and it sits alongside the other land taxing rules. It is not a separate tax with its own rate. Any profit caught by it is added to your other income for the year.

The period is two years, for anything sold from 1 July 2024

For residential property sold on or after 1 July 2024, the bright-line period is two years. This applies no matter when you bought the property. Someone who bought in 2021, when the period was ten years, is now assessed on the two-year rule if they sell today.

Period	Applied to sales	Status in 2026
2 years	Property sold on or after 1 July 2024	Current rule
10 years (5 for new builds)	Sales before 1 July 2024, property acquired from 27 March 2021	Historical only
5 years	Sales before 1 July 2024, property acquired 29 March 2018 to 26 March 2021	Historical only
2 years	Sales before 1 July 2024, property acquired 1 October 2015 to 28 March 2018	Historical only

The separate, shorter period that used to apply to new builds was removed at the same time. There is now one period for all residential land.

The two dates that decide everything

This is where people get caught, because the two ends of the period are measured differently. It is not two years from settlement to settlement.

Date	What date is used	Common exceptions
Start date (buying)	The date the transfer of title is registered with Land Information New Zealand, which is usually your settlement date	Buying off the plans: the date you signed the sale and purchase agreement. Land you have subdivided: the original registration date for the undivided property
End date (selling)	The date you enter into the binding sale and purchase agreement, not settlement	A gift: the date the gift was made

Subdivisions start the clock earlier than people think

If you subdivide land and sell off a section, the clock does not start when the new title issues. It starts on the date the original undivided property was registered to you. That is usually good news. Someone who bought a section in 2021, subdivided it in 2025 and sold the rear lot this year is outside the two-year period, even though the new title is only months old.

Which properties are caught

The test applies to residential land. In practice that means land with a dwelling on it, land you have an arrangement to build a dwelling on, and bare land you could build a dwelling on under the district plan.

• Bare sections are caught. A subdivided residential section with no house on it is still residential land.
• Farmland is not caught. The land must be worked as a farming or agricultural business by you, or be capable of being worked as one because of its area and nature. A lifestyle block with a few sheep on it will usually not qualify.
• Business premises are not caught. Land used predominantly as business premises falls outside the test, so commercial and industrial property is not subject to it. The property does not have to be used as business premises by you: it can be leased to a tenant who runs a business from it.
• Short-stay accommodation is caught. Running a property as short-stay accommodation does not make it business premises for this purpose, unless the property is also your main home.

The main home exclusion, and how it actually works

The main home exclusion is the reason most family homes are never taxed under the bright-line test. For property sold on or after 1 July 2024, you need to pass two tests.

1. The area test. You used more than 50% of the property’s area as your main home, counting the yard, gardens and garage.
2. The time test. You lived in the property as your main home for more than 50% of the bright-line period.

If either one is 50% or less, the exclusion does not apply and the whole profit is taxable. There is no apportionment. It is all or nothing, both ways: pass both tests and none of the profit is taxed, fail either and all of it is.

The time does not have to be continuous. A home rented out while you are overseas, or between moving out and settlement, still counts, as long as the total time it was your main home is more than the total time it was not. Renting a room to a flatmate does not stop the property being your main home. And if you own two properties at once, for example while you are selling the first, both can qualify for different periods.

When the exclusion is lost even though you lived there

• You cannot use the exclusion if you have a regular pattern of buying and selling, or building and selling, your main home. Living in a property before you sell it does not get around this.
• You cannot use it a third time if you have already used it twice in the two years immediately before the sale.
• For a home owned by a family trust, the exclusion is available only if the home sold was a beneficiary’s main home, and either the trust’s principal settlor has no main home or the home being sold is theirs. If the principal settlor lives somewhere else, the exclusion cannot apply to any property the trust owns. This catches a lot of people who put a second home or a student flat into the family trust.

If you built on the property

When you build a new home, the construction period is ignored when working out whether you meet the time test. Only your use before construction started, and from completion to sale, counts. Construction usually ends when the code compliance certificate is issued. That helps if a build ran long, but it also means a short stay in a newly finished house may still fall under 50% of the shortened period.

Other exclusions and rollover relief

Some transfers sit outside the test entirely, and others defer it by passing your original purchase date and cost on to the person receiving the property.

Situation	How it is treated
Inherited property	Not taxable under the bright-line test, including when the beneficiary later sells it
Relationship property settlement	Rollover relief: the person receiving the property inherits the original acquisition date and cost
Transfers between associated persons	Rollover relief where the parties have been associated for at least two years, for transfers from 1 July 2024. Available only once for a property in any two-year period
Transfers into a family trust	Rollover relief where you are associated with the trust and have been for at least two years. The clock does not restart for the trust
Maori land and Treaty settlement land	Rollover relief applies to qualifying transfers

Rollover relief is not the same as an exemption. It moves the clock rather than stopping it, so the person who ends up selling may still face a bright-line bill based on the original owner’s dates. The one piece of good news is that time the original owner spent living in the property carries across too, and counts towards the main home exclusion.

Selling from overseas: the withholding tax deducted at settlement

If you are an offshore person and you sell a New Zealand residential property inside the bright-line period, tax is taken out of the sale proceeds at settlement. This is residential land withholding tax, and your lawyer is legally required to deduct it and pay it to Inland Revenue. You cannot ask for the full proceeds and settle up with Inland Revenue yourself.

The definition of offshore person catches more people than expect it. It includes New Zealand citizens who have been out of the country continuously for three years or more, residence visa holders who have been away for 12 months or more, and anyone without New Zealand citizenship or a residence class visa. Companies and trusts with offshore ownership or control can also be caught.

Clearing two years does not always mean tax free

The bright-line test is one of several land taxing rules, and it is the easiest one to check. Passing it does not mean the sale is untaxed.

• If one of your reasons for buying the property was to resell it, the profit is taxable no matter how long you held it. The intention only has to be one of several reasons, and it is tested at the time you bought.
• If you bought land intending to subdivide and sell part of it, that profit is taxable, even if you live in the part you keep.
• If you, or someone you are associated with, are a property dealer, developer or builder, longer rules apply and the bright-line period is beside the point.

If any of that sounds like your situation, the two-year question is not the one that matters, and this is a conversation for your accountant early rather than late.

What you actually pay, and how you declare it

The taxable amount is the sale price less the purchase price and your deductible costs. Deductible costs include legal fees on both the purchase and the sale, agent’s commission, valuation and survey fees, and capital improvements such as a renovation.

Holding costs are treated differently, and the timing matters. If the property earned rental income, interest, rates, insurance and repairs are generally deductible as you incur them, and you claim them in the year they are incurred rather than at sale. If the property sat empty or was used privately, those costs are usually only deductible from the day you sign the agreement to sell. Interest paid before that date is not deductible at all. Be careful not to claim the same cost twice.

There is no special bright-line tax rate. The profit is added to your taxable income and taxed at whatever rate applies to you or your entity for that year.

A bright-line sale is declared to Inland Revenue on form IR833, filed with your income tax return for the year. You can complete it in myIR as part of the return. You also need to keep the records that support your position, including proof of main home use for each year of the bright-line period, for seven years.

Five things worth doing before you sign

Before you sign

0/0 complete

1. Work out your actual start date from the title registration date, and check whether a subdivision pushes it further back
2. Check whether signing a week or two later would move the sale outside the two-year period
3. Add up the time the property was genuinely your main home and work out whether it clears 50%, and be honest about the gaps
4. If you are living overseas, or the property is in a trust, raise it with us before the property goes on the market
5. Gather the records that support your deductible costs, including invoices for improvements, and talk to your accountant about the rate that will apply

Reset

Most of this comes down to records and dates. Both are much easier to sort out before a sale than after one, and the difference between a taxable and a non-taxable sale can come down to a single signature date.

Where we fit in

Bright-line is a tax question, so your accountant should do the calculation. What we do is the part that determines the answer: reading the agreement, confirming the dates that start and stop the clock, handling the tax statement and any withholding tax obligations at settlement, and making sure the timing of your sale is deliberate rather than accidental. If you are preparing to sell, our selling a property service covers this as part of getting you to settlement.
