Bright-Line Test 2027 Property Tax Calculator NZ
For residential property sold on or after 1 July 2024, New Zealand's bright-line test applies when you sign the sale agreement within 2 years of the date the title was registered to you — new builds and existing homes alike. This 2027 calculator works out the holding period from your dates, checks the main-home exclusion, and estimates the income tax on the gain at current IRD rates.
Date the title was registered to you (usually settlement day).
Date you sign (or plan to sign) the sale and purchase agreement.
Filled in from the two dates. Leave the dates blank to type the months yourself.
Buying and selling costs plus capital improvements. Not rates, insurance, interest or repairs.
The exclusion needs more than 50% of the bright-line period.
Only matters if it was your main home. Count the yard, gardens and garage. Pick 50% or less if, say, you lived in a flat and rented out the house.
The gain is added on top of this and taxed band by band.
Same 2-year test for both since 1 July 2024.
The bright-line test is New Zealand's rule that taxes the profit on residential property sold within a set period. For property sold on or after 1 July 2024 that period is 2 years, measured from the date the title is registered to you until the date you sign the sale agreement. The profit is taxed as income at your marginal rate unless an exclusion applies.
How the 2027 NZ Bright-Line Test Works
Inland Revenue looks at two dates. The bright-line start date for a standard purchase is the day the transfer is registered to you with Land Information New Zealand, usually settlement. The bright-line end date for a standard sale is the day you enter into a binding sale and purchase agreement, not the day the sale settles. If the end date is within 2 years of the start date, the profit is taxable. This applies whenever the property was bought and whether it is an existing home or a new build: the earlier 5-year and 10-year periods only apply to property sold before 1 July 2024. Enter both dates above and the calculator counts the days, shows the date the 2 years run out, and treats a sale agreement signed on or before that second anniversary as inside the period.
The taxable amount is the sale price less the cost of the property. Cost covers the purchase price, buying costs such as lawyer, valuer, surveyor and agent fees, capital improvements such as renovations, and selling costs. Interest, rates, insurance and repairs are holding costs, not part of that cost.
Bright-Line Tax Rates: NZ Income Tax Bands
There is no separate bright-line rate. The net gain is added to your other income for the year and taxed through the ordinary individual bands, so a large gain is usually spread across more than one rate.
| Taxable income (from 1 April 2025) | Rate |
|---|---|
| $0 – $15,600 | 10.5% |
| $15,601 – $53,500 | 17.5% |
| $53,501 – $78,100 | 30% |
| $78,101 – $180,000 | 33% |
| $180,001 and over | 39% |
Worked Example — Investor Sells After 18 Months
An investor buys a rental for NZ$800,000, spends NZ$25,000 on legal fees, agent commission and a new kitchen, and signs a sale agreement for NZ$950,000 eighteen months after the title was registered. The property was never a main home and the investor has NZ$100,000 of other income.
| Step | Working | Result |
|---|---|---|
| Within 2 years? | 18 months | Yes — taxable |
| Gain | NZ$950,000 − NZ$800,000 − NZ$25,000 | NZ$125,000 |
| Taxed at 33% | NZ$100,000 to NZ$180,000 = NZ$80,000 | NZ$26,400 |
| Taxed at 39% | Remaining NZ$45,000 | NZ$17,550 |
| Bright-line tax | NZ$26,400 + NZ$17,550 | NZ$43,950 |
Main-Home Exclusion — When You Pay Zero Tax
The main-home exclusion is all or nothing for sales on or after 1 July 2024. You qualify only if you used more than 50% of the property's area as your main home, counting the yard, gardens and garage, and lived there as your main home for more than 50% of the bright-line period. If either figure is 50% or less the whole gain is taxable; there is no pro-rata exclusion. Inland Revenue's own example: an owner who lived in the home for 381 of 590 days (65%) is excluded, while one who lived in it for 259 of 590 days (44%) pays tax on the full profit. Intending to live there is not enough, a family member living there without you does not count, and you can have only one main home. The exclusion is also lost if you have used it twice in the previous 2 years or have a regular pattern of buying and selling your main home.
Strategy — Holding Period and Acquisition Date
Know your two dates before you list: signing a sale agreement even a day inside the 2 years makes the whole profit taxable, however late settlement falls. Keep invoices for purchase costs, improvements and selling costs, because they reduce the gain. Rollover relief can carry the previous owner's start date and cost across for inherited property, relationship property agreements and, since 1 July 2024, transfers between people who have been associated for at least 2 years. A bright-line loss is ring-fenced: it can only be used against other taxable land sales, not salary or rent. Selling outside the 2 years does not make a sale tax-free if another land rule applies, for example property bought with the intention of reselling.
This calculator estimates income tax only, for one individual owner. If you co-own, enter your share of the prices and costs. It does not cover companies or trusts, residential land withholding tax for offshore sellers, or property sold before 1 July 2024.

Frequently Asked Questions
What is the bright-line period in 2027?
2 years. For residential property sold on or after 1 July 2024, the bright-line test applies if your bright-line end date is within 2 years of your bright-line start date, whenever the property was bought. The older 5-year and 10-year periods only apply to property sold before 1 July 2024.
How is the 2-year bright-line period measured?
For a standard purchase it starts on the date the transfer of title is registered to you with Land Information New Zealand, which is usually settlement day. For a standard sale it ends on the date you enter into a binding sale and purchase agreement, not the settlement date. An off-the-plan purchase starts on the date of the purchase agreement instead.
Does the main-home exclusion always apply?
No. You can claim it only if you used more than 50% of the property area as your main home and lived in it as your main home for more than 50% of the bright-line period. If either figure is 50% or less the whole gain is taxable, because there is no partial exclusion for sales on or after 1 July 2024. It is also unavailable if you have already used it twice in the previous 2 years or have a regular pattern of buying and selling your main home.
Is the bright-line a flat tax?
No. The net gain is added to your other income for the year and taxed at the individual income tax rates: 10.5% up to $15,600, 17.5% up to $53,500, 30% up to $78,100, 33% up to $180,000 and 39% above that. These are the Inland Revenue rates that apply from 1 April 2025.
Can I deduct costs?
Yes. Inland Revenue lets you deduct the cost of the property: the purchase price, purchase costs such as lawyer, valuer, surveyor and agent fees, capital improvements such as renovations, and selling costs such as lawyer and agent fees. Holding costs such as interest, rates, insurance and repairs are not part of that cost. Where they are deductible they are claimed in the year they are paid, usually against rental income.
Are new builds subject to the bright-line test?
Yes. For sales on or after 1 July 2024 new builds are treated the same as every other residential property and the 2-year test applies. The separate 5-year period for qualifying new builds only applied to property sold before 1 July 2024.
What about inheritance?
Inland Revenue says the bright-line test does not apply to the executor or administrator of a deceased estate, and a later sale of inherited residential property by the beneficiary is generally not taxable under the bright-line test either. If you buy another person out of their share of an inherited property, that purchased share can be taxed if you sell within the bright-line period.
Can I use a loss against other income?
No. A bright-line loss is ring-fenced. It cannot reduce salary, rental or business income and can only be used against profits from other taxable land sales, including bright-line sales, in the same or a later income year.
