Bright-line test changes July 2026

There are no bright-line test changes coming in July 2026. The rules remain exactly as they were after the July 2024 update.

This might surprise you if you've been planning around expected changes. Many property investors assume the bright-line rules shift every few years. They don't. The current 2-year period stays put.

What actually applies in July 2026

If you're selling a rental property in July 2026, the bright-line test works like this:

For properties bought after 2022: The 2-year rule applies. Sell within 2 years of your LINZ registration date, and you pay tax on any gain. Sell after 2 years, and bright-line doesn't apply.

That's it. No special July 2026 threshold, no new exemptions, no rate changes.

Why people expect July 2026 changes

The confusion comes from the bright-line test's history of frequent changes:

Period	Bright-line period	Who it applied to
2015-2018	2 years	Non-main homes
2018-2021	5 years	Non-main homes
2021-2024	10 years (5 for new builds)	Non-main homes
2024-now	2 years	Non-main homes

With changes every 3-4 years, expecting another shift in 2026 seems logical. But no legislation is planned. The government confirmed the 2-year period as settled policy.

Which rule applies to your property

Your sale date determines which bright-line period applies—not your purchase date. This catches many people out.

Properties sold on or after 1 July 2024: 2-year period applies, regardless of when you bought.

Properties sold before 1 July 2024: The old periods applied (5 or 10 years, depending on purchase date).

Since we're now in 2026, any sale you make follows the 2-year rule. Even if you bought in 2021 under the old 10-year period.

How the 2-year period works

The bright-line period runs from your "start date" to your "end date."

Start date: Usually your LINZ title registration date. For off-the-plan purchases, it's your sale and purchase agreement date.

End date: When you sign a binding sale agreement.

If the gap is less than 2 years, bright-line tax applies. More than 2 years, and you're clear.

Example: 2025 purchase, 2026 sale

You bought a rental property in Auckland:

• LINZ registration: 15 March 2025
• Sale agreement signed: 10 April 2026
• Time held: 12 months, 26 days

Since this is under 2 years, bright-line tax applies to any gain.

Main home exclusion changes that did happen

While the bright-line period didn't change in July 2026, the main home exclusion rules did change in July 2024. These affect mixed-use properties.

New rule (from July 2024): If your property was your main home for more than 50% of the time you owned it, the entire gain is exempt from bright-line tax.

Old rule (pre-July 2024): You could claim a partial exemption based on the exact percentage of main home use.

This "all or nothing" approach means if you used a property as your main home for 60% of ownership, you get full exemption. Use it for 40%, and you get nothing.

What you pay if bright-line applies

Bright-line gains are taxed as regular income, not capital gains. They're added to your other income and taxed at your marginal rate.

NZ tax rates for 2025/26:

• $0 to $15,600: 10.5%
• $15,601 to $53,500: 17.5%
• $53,501 to $78,100: 30%
• $78,101 to $180,000: 33%
• Over $180,000: 39%

Worked example: $100,000 gain

If you earn $80,000 from your job and make a $100,000 bright-line gain, your total income becomes $180,000. The gain gets taxed at 33% (your new marginal rate), costing $33,000 in tax.

Common mistakes to avoid

Using the wrong start date: LINZ registration, not settlement, typically starts the clock. For off-plan purchases, it's your original sale agreement date.

Assuming old rules apply: Properties bought in 2021 but sold in 2026 follow the 2-year rule, not the old 10-year period.

Forgetting the main home test: If you lived in the property as your main home for more than half the ownership period, you might qualify for full exemption.

Missing deductible costs: You can deduct purchase costs (legal fees, building inspections) and sale costs (agent fees, legal fees) from your gain.

Planning for actual sales in July 2026

If you're planning to sell in July 2026, focus on timing rather than rule changes.

Properties bought before July 2024: You've likely already passed the 2-year threshold. Bright-line won't apply.

Properties bought in late 2024 or 2025: Check your exact dates. A few extra weeks of ownership might save thousands in tax.

Mixed-use properties: Document your main home usage carefully. The 50% threshold can mean full exemption.

What could change (but probably won't)

While no changes are scheduled for July 2026, future governments could modify bright-line rules. Possible changes might include:

• Extending the period back to 5 or 10 years
• Creating different periods for different property types
• Changing the main home exclusion rules
• Adding minimum gain thresholds

None of these are proposed or likely under current policy settings. The 2-year period appears settled for the foreseeable future.

IRD reporting requirements

If bright-line tax applies to your July 2026 sale, you must file an IR3 or IR330 tax return by 7 July 2027. IRD won't automatically know about your property sale—you must declare it.

Include all relevant documents: sale agreements, purchase records, improvement costs, and evidence of any main home use.
