Let’s dive into the key questions New Zealand property owners are asking — and help you make smarter decisions when it’s time to sell.
Do you pay tax when selling a rental property in NZ?
If you’re planning to sell a rental, don’t assume the profit goes straight into your pocket. In New Zealand, selling a rental property often triggers income tax, especially under the Bright-Line test. But even if you’re outside that timeframe, other rules could still apply depending on your intent or past deductions.
Here’s when tax usually applies:
- You sell the property within 10 years of purchase (or 5, depending on the acquisition date).
- You bought the property with the intention to resell it.
- You’ve claimed deductions, such as depreciation, and need to account for depreciation recovery.
Selling for a gain? Be ready to account for it. And yes, the IRD is watching.

Understanding the bright-line test in 2025
The Bright-Line test is often misunderstood as a capital gains tax, but it’s technically a rule that treats profits from the sale of residential property as taxable income when sold within a certain period.
What is the Bright-Line test?
This test applies when you sell a residential property within a set number of years from the date you acquired it. The number of years depends on when you bought the property:
- 2 years for properties acquired between 2015 and 2018.
- 5 years for those purchased from 29 March 2018 to 26 March 2021.
- 10 years for most properties bought on or after 27 March 2021.
Some exemptions exist — mainly for your main home, inherited property, or transfers due to relationship breakups. But rental properties? They’re almost always caught.
For deeper understanding, refer to the IRD’s Bright-Line rule breakdown.
How it applies to rental properties
Rental properties are prime targets for the Bright-Line rule. If you’ve rented out a house and now want to sell, you need to ask yourself:
- How long have you owned the property?
- Have you lived in it at any point?
- Was the intention always to keep it long-term?
If you’re inside the Bright-Line period, you’ll need to declare your profit as taxable income. You can’t offset it as a “capital gain” because the rule overrides that distinction.

Other tax implications when selling a rental property
Even if you’re outside the Bright-Line period, the tax story doesn’t end there. There are other less-known rules that could still apply — and they catch out many investors.
Depreciation recovery: what it means
If you claimed depreciation on the building structure or chattels over the years, the IRD may require you to add back some of those deductions. That’s what’s known as depreciation recovery — and yes, it can increase your taxable income at sale.
What triggers depreciation recovery?
- You’ve claimed depreciation on the building or assets.
- You’re selling the property for more than the adjusted book value.
This often happens when market prices rise and your sale value exceeds what’s recorded in your books.

GST and residential rentals — does it apply?
Most residential property sales are not subject to GST. However, if you’ve used the property for short-term Airbnb or mixed-use (residential and commercial), it gets murky.
Key GST points:
- Residential rentals: GST usually doesn’t apply.
- Short-term accommodation: May trigger GST registration and obligations.
- Commercial mixed-use: Needs a proper tax advisor review.

How to minimise tax when selling your investment property
No one likes overpaying tax — and fortunately, there are legal strategies you can use to keep more of your profits. Here’s how smart investors prepare for sale.
Timing the sale after the Bright-Line period
This is the most obvious — but most effective — tactic. Holding the property just a few months longer might mean the difference between paying tens of thousands in tax or nothing at all.
Ask yourself:
- Can I delay the sale to move outside the Bright-Line window?
- Does the date of the sale agreement fall outside the test period?
Just remember: it’s the contract date, not settlement date, that the IRD looks at.
Offsetting costs and losses
You may be able to reduce your taxable gain by factoring in:
- Legal fees for the sale
- Agent commissions
- Remaining chattel values
- Historical losses (if not ring-fenced)
Keep good records and speak to a tax specialist. For example, if you’re planning a 1031-style rollover, this article might help: Rollover capital gains on property.
Structuring the sale smartly
Consider how the property is owned:
- In a personal name?
- In a trust or LTC?
- Through a company?
Each structure has different tax implications — especially when it comes to distributing income or losses. It’s worth discussing this with a qualified accountant.
Example scenarios and tax calculation table
Let’s look at how these rules play out in real life. Here are three simplified examples:
| Scenario | Years Owned | Bright-Line Applies? | Estimated Tax |
|---|---|---|---|
| Sold after 3 years | 3 | Yes (10-year rule) | $35,000 |
| Gifted to child | 7 | No (main home rule) | $0 |
| Sold after 12 years | 12 | Depends on intent | Varies |
