Investment Property Tax in New Zealand: What Every Investor Should Know

1. Tax on Rental Income

In case you receive income by renting out a premise, it is taxable. All rental income must be declared on the Inland Revenue Department (IRD), whether the property is owned by an individual, a joint owner, a company, or a trust.

Key Points:

• Rental Income includes: the rent taken in, money held on bond to cover damages, insurance payment covering loss of rent, and tenant reimbursements.
• Income bracket: Gains of rental incomes are contributed to your overall income and taxed respectively (at constantly progressive tax rates).
• Claim allowance: including property management costs, rates, insurances, repairs, and mortgage interest.

Deductible Expenses and Mortgage Interest

In the past, property renters were in a position to claim interest on loans that were used to purchase the rental property. This has, however, been altered by recent tax reforms.

Interest Deductibility (as of 2025):

• New Builds: Mortgage interest is deductible on a 20-year basis as of the date of the CCC (Code Compliance Certificate).
• Existing Properties: Phase out 2021 -2025. At this point, the majority of investors are unable to deduct any mortgage interest on the second-hand properties.
• Repairs vs Improvements: Maintenance repairs are treated as an expense and are deductible; capital improvements, such as the addition of a room or a kitchen fit-out, are treated as a capital expense and are non-deductible but capitalised and depreciated.

The Bright-Line Property Rule

The Bright-Line Rule is the New Zealand form of capital gain tax on residential premises. In case you sell a property within a given period, you might be required to pay taxes on the gain.

What’s the Rule in 2025?

• 10-year Bright-Line Period: All residential investment properties sold after 10 years from their acquisition are liable to a tax on the gain.
• New Builds Specifics: Where it is a new build, a 5-year bright-line period will apply.
• Main Home Exemption: You get an exemption for your properties that are used as your main home most of the time.
• Inherited Property: Does not count towards bright-line when transferred as part of a deceased's Estate.

Holding Property Through a Trust or Company

Investors tend to consider the need to hold properties in trusts and limited liability companies to protect assets and arrange taxes.

Key Considerations:

• Trusts: This is divided among taxpayers at a lower bracket and should be well managed.
• Companies: 28 per cent tax on income, not as flexible as a trust.
• One should always discuss with a tax consultant as to the best way to establish structures because an entrant could result in the IRD scrutiny in case its utilisation is not to the best.
