The bright-line test taxes the profit when you sell a residential property too soon after buying it. For any property sold on or after 1 July 2024, the bright-line period is two years, from when you bought it.
You’re partway through selling a rental in Mount Maunganui. Your agent mentions the bright-line test. Then your lawyer asks when the title was transferred to you. Then you realise the dates matter more than the price, and you want a straight answer before you sign.
Quick summary
The bright-line test NZ property owners face requires taxes on its profit when you sell. For any property sold on or after 1 July 2024, the bright-line period is two years. This is the case no matter when you bought it after the said date. The 2-year period begins when the title transfers to you. It stops when you enter into a binding sale and purchase agreement. Gains are taxable at your marginal rate of up to 39%. Under the bright-line test rules NZ applies, your main home, inherited property, business premises and farmland can each take a sale outside the test.
How does the bright line test work?
The test compares two dates. If the end date falls within two years of the bright-line test start date, your profit on selling residential property is considered taxable income.
| Date | When it’s set |
|---|---|
| Start date | Usually the date the property title transfers to you and is registered with LINZ |
| End date | Usually the day you enter into a binding sale and purchase agreement |
That second row catches most people by surprise, since few realise that the end date is the day you sign rather than settlement day.
Inland Revenue is clear on this. For property sold on or after 1 July 2024, it compares your end date against your start date. The same rules apply to New Zealand tax residents who buy and sell residential property overseas.
How the bright line test changes through the years
New Zealand’s bright-line rules have changed three times since they came in in 2015. What binds you to this rule will depend on when you sell, and not when you bought.
| Rule change | Bright-line period |
|---|---|
| From 1 October 2015 | 2 years |
| From 29 March 2018 | 5 years |
| From 27 March 2021 | 10 years, or 5 years for new builds |
| From 1 July 2024 | 2 years, all residential property |
Here’s where the market gets a bit confused. Plenty of resources still say the rule that applied when you bought the property is the one that binds you. That is no longer the case after July 2024.
Your sale date triggers the 2 years, and not your purchase date. Buy a rental in 2022, for example, sell it today, and the bright-line test 2-year rule applies. The previous 10-year bright-line rule no longer holds. These are the changes that the 2024 bright-line test ushered in.
If you’ve held a Papamoa or Te Puke rental, and still expect to wait longer, then it’s wise to revisit it as soon as possible.
When the bright line test doesn’t apply to your sale
Even within the two-year window, a sale can fall outside the bright-line test if it qualifies for one of four exclusions or the one main relief provision.
These bright-line test exemptions each work differently, so check which fits your situation.
- Your main home. Selling your main home is generally outside the rules. The bright-line test main home exclusion applies where you used more than half the property as your main home for more than half your ownership.
- Inherited property. The bright-line test inherited property exclusion covers what you receive as a form of inheritance, whether directly or via an executor or administrator.
- Business premises. A property bought for business purposes, and genuinely used that way, is exempt from residential rules.
- Farmland. Working farmland is excluded following the same reasoning.
- Rollover relief. Bright-line test rollover relief means some transfers don’t trigger the clock. That includes certain moves into a family trust where the principal settlor and the beneficiaries of the trust match the original owners.
If you’re not sure whether the bright-line test applies to your property, Inland Revenue’s Property Tax Decision Tool will run your dates. Treat it as a first check, and not sole advice on a real sale.
How much tax you’ll pay if the bright line rule applies
There’s no separate bright-line tax rate. The gain is added to your income and taxed at your marginal rate, topping out at 39%.
Here’s a sample Mount Maunganui rental, sold inside this window:
| Item | Amount |
|---|---|
| Sale price | $920,000 |
| Purchase price | $780,000 |
| Selling and legal costs | $28,000 |
| Capital improvements | $22,000 |
| Taxable gain | $90,000 |
If your other income is already at $180,000 and above, that $90,000 is taxed at 39%, so you’re looking at roughly $35,100 to pay. On a lower income, the rate drops because the gain stacks on what you already earn.
There are two things here that can caught some people off guard. Paying taxes on the gain happens through your usual return, so be sure to set money aside at settlement. A bright-line loss is also ring-fenced, so you can’t offset it against salary.
What to do before you sign a sale and purchase agreement
Check your dates first – we can’t overstate this. Because almost every problem here starts with someone signing before they’ve figured out when their two years began.
- Find the date the property title was registered to you.
- Count two years forward. If today is included in that period, then assume the sale is subject to the bright-line test.
- Check whether an exclusion fits. See also if the main home exclusion applies to you.
- Note any transfer since purchase. Trust changes and co-ownership shifts move your start date.
- Estimate the tax, then confirm it before you sign. Be sure to verify while you can still time the sale.
Timing is the lever you control. Selling one month later can decide whether a gain is taxable under the bright-line rules. Check these first against the wider capital gains tax rules on property and the current Labour CGT proposal.
Frequently asked questions
What is the bright-line rule in New Zealand?
The bright-line rule taxes profit on a short-held residential property sale as income. It’s often called New Zealand’s version of a capital gains tax on property. The NZ bright-line test only takes effect where a sale falls inside the bright-line period, a rule applied since October 2015.
How to avoid bright-line tax in NZ?
Timing and exclusions are the legitimate routes to avoiding bright-line tax. Hold past the two-year mark, or check whether you can sell your main home, or a property covered by the inherited, business premises, or farmland exclusion. Rollover relief may cover a transfer. What doesn’t work is dressing up a short hold as something else since Inland Revenue matches sales against LINZ title data. People in the business of building and selling face separate rules again.
How long is the bright-line test in NZ?
Two years, for residential property sold on or after 1 July 2024. Older sales use the period that applied at the time. The 5-year version of the bright-line test applies when the property was acquired from 29 March 2018 and sold before July 2024.
Where this leaves you
The bright-line test changes that were made in 2024 gave us simpler property tax rules. But bear in mind that the dates still determine the rest. Two years may sound generous, until you realise your end date is the day you sign.
