Rental property income is taxable in New Zealand. But the tax treatment of rental property is complex — deductible expenses, ring-fencing rules, interest deductibility changes, and the bright-line test all interact to determine your actual tax liability.
Rental income is taxed at your marginal income tax rate (up to 39%). You can deduct most rental expenses — from April 2026, 100% of mortgage interest is deductible again. Rental losses are ring-fenced (can't offset salary). Depreciation on the building itself is not claimable but chattels depreciation is. If you sell within 2 years, capital gains are taxable (bright-line test). Most landlords file an IR3 and use an accountant.
Rental Income Is Fully Taxable
All rent received is income. This includes:
- Weekly or fortnightly rent payments
- Bond retained (if kept due to damage)
- Income from boarders (above the boarder exemption threshold)
- Airbnb and holiday rental income (may have GST implications if over $60,000/year)
Tax rate: Rental income (net of deductions) is added to all other income and taxed at your marginal rate:
| Income band | Rate |
|---|---|
| Up to $14,000 | 10.5% |
| $14,001–$48,000 | 17.5% |
| $48,001–$70,000 | 30% |
| $70,001–$180,000 | 33% |
| Over $180,000 | 39% |
A landlord earning $100,000 from employment and $20,000 net rental income pays 33% on the $20,000 rental income.
Deductible Expenses
From April 2026, landlords can deduct the following:
| Expense | Deductible? | Notes |
|---|---|---|
| Mortgage interest | ✅ 100% | From 1 April 2026 — fully restored |
| Rates | ✅ Yes | Full deduction |
| Insurance (landlord’s) | ✅ Yes | Contents and building |
| Property management fees | ✅ Yes | Typically 8–10% of rent |
| Maintenance and repairs | ✅ Yes | Ongoing; not capital improvements |
| Accounting fees | ✅ Yes | For rental schedule preparation |
| Legal fees (tenancy disputes) | ✅ Yes | Tenant disputes, lease issues |
| Advertising (finding tenants) | ✅ Yes | Trade Me listings, etc. |
| Travel (to inspect property) | ✅ Partial | NZ properties, documented |
| Chattels depreciation | ✅ Yes | Carpets, appliances, blinds, etc. |
| Building depreciation | ❌ No | Removed in 2011 (non-residential exempt) |
| Capital improvements | ❌ No | Added to cost base (reduces bright-line gain) |
| Mortgage principal | ❌ No | Never deductible |
Capital Improvements vs Repairs
A critical distinction for landlords:
Repairs and maintenance (deductible):
- Fixing a broken fence
- Repainting walls to same standard
- Replacing worn carpet like-for-like
- Unblocking drains
Capital improvements (not deductible now, but increase cost base):
- Adding a new room or extension
- Replacing a wooden deck with a larger concrete deck
- Installing a heat pump where there was none
- Renovating kitchen to a significantly higher standard
The distinction can be grey — IRD guidance and a tax adviser help with borderline cases. Capital improvements do reduce your bright-line gain when you sell, so they’re not wasted from a tax perspective — just deferred.
Chattels Depreciation
While you cannot depreciate the building, you can depreciate chattels (items inside the property). Common examples:
| Chattel | IRD depreciation rate (DV) |
|---|---|
| Carpet | 25% |
| Dishwasher | 25% |
| Oven/cooktop | 30% |
| Heat pump | 16% |
| Blinds/curtains | 25% |
| Washing machine | 21% |
| Hot water cylinder | 8% |
A chattels valuation (performed at purchase) establishes the value of each item. This is a one-time cost ($400–$700 from specialist valuers) that saves tax over many years. Worth doing at purchase.
Ring-Fencing of Rental Losses
Since 2019, rental losses are ring-fenced — they cannot offset your salary or other business income.
How ring-fencing works:
- If deductible expenses > rental income → rental loss
- Rental loss carried forward to the next year
- Future rental income (from any residential rental) offsets carried-forward losses
- When you sell the property, any remaining carried-forward losses can offset the gain on sale
Example (2026):
- Rental income: $30,000
- Deductible expenses: $55,000 (including $40,000 mortgage interest)
- Rental loss: $25,000 → ring-fenced, carried forward
- This does NOT reduce your PAYE income tax in 2026
Ring-fencing is significant for negatively geared investors. Full interest deductibility increases the deductible expense — but if you’re already loss-making, the additional deduction just increases your carried-forward loss rather than immediately reducing your tax.
GST and Rental Properties
Residential rental: Exempt from GST. You cannot register for GST on residential rental income and cannot claim GST back on expenses.
Short-stay/holiday rental (Airbnb): If you earn more than $60,000/year from holiday rentals, you must register for GST, charge GST at 15% on accommodation, and can claim GST back on expenses. Mixed residential/holiday use creates a partial GST apportionment.
Commercial property: GST-registered landlords charge and claim GST.
Filing Your Rental Tax Return
Landlords file an IR3 individual income tax return with an IR3R rental income schedule.
The IR3R captures:
- Property address
- Rental income
- Each category of deductible expenses
- Net rental income or loss
- Carried forward losses
Filing deadline: 7 July after the tax year end (31 March). If you have a tax agent, extended deadlines may apply.
Do you need an accountant? Not legally required — but strongly recommended for:
- Multiple properties
- Complex ownership structures (LTC, trust, company)
- Mixed use properties
- Significant depreciation claims
Accountant fees for a rental schedule: $500–$1,500/year depending on complexity.
Ownership Structures and Tax
| Structure | Tax treatment |
|---|---|
| Individual | Marginal rate on net income |
| Joint ownership | Split proportionally to ownership share |
| Look-Through Company (LTC) | Income/losses flow through to shareholders |
| Trust | Taxed at 33% (trustee rate) unless distributed |
| Standard company (Ltd) | 28% corporate tax rate |
An LTC is common for property investors wanting to flow losses through to personal returns while maintaining legal separation. However, ring-fencing still applies within the LTC — losses still can’t offset salary income from outside the LTC.
Frequently Asked Questions
Do I pay tax on capital gains from property? Only if you sell within the bright-line period (2 years from July 2024). Outside the bright-line, NZ does not have a general capital gains tax. Property sold after 2 years of ownership (and not otherwise classified as trading stock) is not subject to capital gains tax.
Can I split rental income with my partner to reduce tax? Only if they are actually part-owner of the property. Each person pays tax proportional to their ownership share. You cannot split income between spouses without actual ownership structure.
I’m renting a room in my own home — is that taxable? Up to a threshold, income from a boarder in your own home is tax-free. From 1 April 2024, the IRD flat rate standard cost threshold is $202/week per boarder ($218/week from 1 April 2025). Income above this threshold is taxable.
