NZ Bright-Line Test: What Landlords Need to Know
The bright-line test can make part or all of your property-sale gain taxable in New Zealand. This guide helps you assess exposure and prepare records before sale.
Quick Answers: Bright-Line Tax
What is bright-line tax?
Bright-line is an income-tax rule that can tax your profit when you sell residential property within a set period. It is not a separate tax type — it is taxable income in your return.
When does it usually apply?
In most landlord scenarios, if you sell inside your applicable bright-line period, your gain is usually taxable unless an exclusion (for example, main home conditions) or rollover relief applies.
How do I work out my period?
The key dates are your acquisition cohort and your sale date. Use this practical table as a first pass:
| Scenario | Likely bright-line period to test | What this means in practice |
|---|---|---|
| Property sold on or after 1 July 2024 | 2 years | If disposal is within 2 years of the relevant start date, gain is generally taxable unless an exclusion applies. |
| Property sold before 1 July 2024 and acquired between 29 Mar 2018 and 26 Mar 2021 | 5 years | Sales inside 5 years were generally within bright-line scope. |
| Property sold before 1 July 2024 and acquired on or after 27 Mar 2021 | Typically 5 years for qualifying new builds, 10 years for others | You needed to test the property category and acquisition cohort before concluding taxable status. |
Simple bright-line exposure estimator
This estimator is educational and does not replace advice. It helps you compare gain, deductible sale costs and indicative taxable amount.
Common records IRD expects
- Signed sale and purchase agreements
- Settlement statements and legal invoices
- Evidence supporting any claimed exemption
- Chronology of occupancy/use where relevant
- Documents for ownership changes or transfers
Most Common Scenarios (Direct Answers)
I bought and sold a rental inside the bright-line period. Is it taxable?
Usually yes. In most cases the gain is taxable, subject to allowable adjustments and any valid exclusion/relief.
I sold my main home. Do I pay bright-line tax?
Often no, if the main home exclusion criteria are satisfied for your specific acquisition cohort and use pattern. Mixed-use periods can change this outcome.
I transferred property to another ownership structure. Is that still a "sale"?
Sometimes yes. Certain transfers can still trigger bright-line outcomes unless rollover relief applies.
What usually causes errors?
- Using the wrong bright-line period for the acquisition cohort
- Incorrect start/end date assumptions (non-standard deals)
- Claiming exclusions without robust timeline evidence
- Missing acquisition/disposal cost documents
Timing strategy before signing a contract
- Confirm relevant bright-line period for your acquisition date.
- Estimate taxable outcome under both base and conservative sale-price scenarios.
- Check whether offsetting losses or deductions are available in the same period.
- Review all legal and agent costs to ensure full support for adjustments.
What to Do Before You Sign a Sale Contract
- Confirm your bright-line period based on acquisition cohort and sale date.
- Check whether any exclusion/rollover relief is actually available for your facts.
- Prepare a documented gain estimate (conservative and base-case sale values).
- Compile evidence pack: agreements, settlement docs, legal/agent costs, occupancy timeline.
