Quick Answer
The bright-line test taxes profit from selling residential property as income if the property is sold within a set period. From July 2024, the test applies to properties sold within 2 years of purchase — reduced from the previous 10-year rule. The main home exemption applies if you lived in the property for most of the ownership period. Investment properties sold within 2 years with no exemption are taxed on the full profit at your marginal income tax rate (up to 39%). The test does not apply to commercial property or farmland.
What Is the Bright-Line Test?
The bright-line test is a rule that taxes the profit on residential property sold within a set period of buying it. New Zealand doesn’t have a general capital gains tax — but the bright-line test functions as one for short-term property sales.
If you sell a residential property within the bright-line period and no exemption applies, the profit is treated as income and taxed at your marginal tax rate (up to 39%). The more you earn, the more tax you pay.
The bright-line period has changed several times. It started at 2 years (2015), extended to 5 years (2018), then to 10 years for most properties (2021). The National-led government reduced it back to 2 years from 1 July 2024. If you purchased before that date, earlier rules may still apply to you.
Which Rule Applies to Your Property?
The bright-line period that applies depends on when you purchased the property, not when you sell it. This is critical — properties bought years ago may still be subject to the 5- or 10-year rules.
If you bought a residential property between 27 March 2021 and 30 June 2024, the 10-year bright-line period applies to you regardless of the 2024 law change. A property bought in 2022 won’t be outside the bright-line window until 2032. Always confirm with a tax adviser before selling.
What Properties Does It Apply To?
The bright-line test applies to residential land in New Zealand. This is broader than just houses — it includes bare land that could be used for residential purposes.
- Residential houses, townhouses and units
- Apartments and flats
- Bare land zoned or suitable for residential use
- Holiday homes and baches (unless main home exemption applies)
- Mixed-use residential/commercial properties (residential portion)
It does not apply to:
- Commercial, industrial or farm land
- Overseas property
- Property sold under the main home exemption (see section 5)
How Is the Tax Calculated?
Bright-line income is the profit on sale — sale price minus the original purchase price and allowable costs. This profit is added to your other income for the year and taxed at your marginal rate.
Costs you can deduct to reduce your taxable profit include:
- Purchase price of the property
- Legal fees, due diligence, and conveyancing costs on purchase and sale
- Capital improvements you made to the property (not repairs or maintenance)
- Real estate agent commissions on sale
If this investor already earns $100,000 from their job, the $90,000 bright-line income pushes their total to $190,000. The $90,000 is taxed at 39% (over $180,000 threshold) = approximately $35,100 in tax on the gain.
When Does the Bright-Line Test Not Apply?
Several exemptions can remove a property sale from bright-line entirely. The most important is the main home exemption — but it is frequently misunderstood.
You can only have one main home at a time. If you own multiple properties, only one qualifies for the main home exemption. IRD uses a “most of the time” test — the property must have been your main residence for the majority of your ownership period. Renting it out for extended periods can disqualify the exemption.
When Does the Clock Start and End?
The bright-line period starts on the date the property title is registered in your name on LINZ. It ends on the date you sign a sale and purchase agreement to sell (not settlement).
If you bought off the plan, the bright-line clock starts when the title registers, not when you signed the purchase contract. This means a property contracted years before completion may have a shorter bright-line window than you expect. Check your LINZ title registration date, not your contract date.
Common Scenarios — Does the Bright-Line Apply?
- You buy a rental in 2025 and sell it in 2026 at a profit. The 2-year rule applies. You signed a sale agreement within 2 years of title registration — bright-line tax applies.
- You buy your family home in 2025 and need to sell it in 2026 due to a job move. Main home exemption applies — no bright-line tax if it was genuinely your principal residence.
- You bought a rental in 2022 and want to sell in 2026. The 10-year rule applies (bought during Mar 2021–Jun 2024 window). You are inside the 10-year period — bright-line tax applies unless an exemption does.
- You inherit a house and sell it the following year. Inherited property is exempt. No bright-line tax regardless of the gain.
- You sell at a loss. If the sale price is less than the purchase price and costs, there is no profit and no bright-line tax. You cannot claim the loss against other income.
Rental income you received while owning the property is taxed each year as ordinary income, regardless of bright-line. The bright-line tax only applies to the profit on sale. Both apply independently — a rental property can trigger both rental income tax annually and bright-line tax on sale.
What Investors Should Do
Whether you are planning a purchase, already own investment property, or are considering selling, here is what to keep on your radar.
- Know your title registration date. This is your bright-line start date. Download it free from the LINZ website (linz.govt.nz). It is not the same as your contract date or settlement date.
- Keep receipts for capital improvements. Every dollar of genuine capital improvement reduces your taxable gain. Repairs and maintenance do not count, but new bathrooms, extensions and major renovations do.
- Disclose on your tax return. If you sell inside the bright-line period, you must disclose the gain in your IR3 income tax return for that year. Failure to disclose is a compliance risk with IRD.
- Plan your sale timing. If you are close to the end of your bright-line period, it may be worth waiting to sign the sale agreement until after the period expires — even if settlement happens later.
- Get specialist tax advice. The rules around mixed-use properties, short-term rentals, the main home exemption, and trust ownership are complex. A property tax accountant will save you more than their fee.
