Rental income in NZ is taxed at your marginal income tax rate, which ranges from 10.5% to 39% depending on your total income (IRD). You can deduct expenses like rates, insurance, property management, and maintenance. Mortgage interest is now fully deductible again for most residential rental properties following the reversal of interest deductibility restrictions from 1 April 2024 (IRD). Rental losses are ring-fenced, meaning they can only offset income from other rental properties, not your salary or wages.
Use the Forge Money PAYE calculator to check your marginal tax rate, which determines how your rental income is taxed.
How rental income is taxed in NZ
Rental income is treated as assessable income by IRD. It gets added to your other income (salary, wages, interest, dividends) and taxed at your marginal rate under NZ's progressive tax system (IRD).
| Total taxable income (including rental) | Marginal tax rate |
|---|---|
| $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% |
| $180,001+ | 39% |
If you earn $80,000 in salary and $15,000 net rental income, your total taxable income is $95,000. The rental income falls entirely in the 33% bracket, so you'll pay $4,950 in tax on that rental income (IRD).
You declare rental income in your individual tax return (IR3). If you haven't filed an IR3 before, see our guide to filing a tax return.
Assessable rental income: what to include
All amounts you receive from renting out residential property count as assessable income (IRD):
| Income type | Taxable? |
|---|---|
| Weekly/fortnightly rent payments | Yes |
| Bond money retained for damage | Yes (when retained, not when received) |
| Insurance payouts for lost rent | Yes |
| Payments from boarders (above exempt amount) | Yes (first $231/week for one boarder is exempt for 2025-26) |
| Letting fees charged to tenants | Yes |
| Key money or premiums | Yes |
| Reimbursements from tenants for expenses | Yes |
If you have a boarder (someone living in your own home), the first $231 per week for one boarder is exempt from tax for the 2025-26 year (IRD standard cost method). Amounts above that are taxable, or you can use the actual cost method and claim a portion of household expenses.
Deductible expenses for rental properties
You can deduct expenses incurred in earning your rental income. These reduce your taxable rental profit (IRD):
| Expense | Deductible? | Notes |
|---|---|---|
| Mortgage interest | Yes (see interest deductibility section) | Fully deductible from 1 April 2024 for most properties |
| Council rates | Yes | Full amount for the rental property |
| Insurance (building, landlord) | Yes | Premiums for the rental property |
| Property management fees | Yes | Agent fees, typically 7% to 10% of rent |
| Repairs and maintenance | Yes | Repairs that restore the property, not improvements |
| Body corporate fees | Yes | For apartments and units |
| Water rates | Yes | If paid by the landlord |
| Accounting fees | Yes | Cost of preparing rental accounts and tax return |
| Legal fees | Partially | For rental-related matters, not purchase/sale costs |
| Advertising for tenants | Yes | Listing fees, advertising costs |
| Travel to the property | Yes | For inspections, maintenance. Not personal visits. |
| Depreciation on chattels | Yes | Furniture, appliances, curtains, carpets in the rental |
| Land tax / land rates | Yes | Full amount |
Capital expenses are not deductible. If you renovate a bathroom or add a new deck, that's a capital improvement, not a repair. Capital costs are added to the cost base of the property, which matters if the bright-line test applies on sale. The distinction between a "repair" (deductible) and an "improvement" (capital) is a common area of dispute with IRD (IRD).
Interest deductibility rules (current as of 2025-26)
Interest deductibility for residential rental properties has changed multiple times in recent years. Here's where things stand now (IRD):
Current rules (from 1 April 2024)
The Government restored full interest deductibility for residential rental property from 1 April 2024. This means mortgage interest on residential investment properties is 100% deductible against your rental income, the same as it was before the 2021 changes (IRD).
What happened (timeline)
| Period | Interest deductibility | What it meant |
|---|---|---|
| Before 1 October 2021 | 100% deductible | Full deduction allowed |
| 1 October 2021 to 31 March 2023 | Phasing out (new purchases: 0% from day one) | New purchases got no deduction; existing properties phased out |
| 1 April 2023 to 31 March 2024 | 50% deductible (existing properties) | Only half of interest could be deducted |
| From 1 April 2024 | 100% deductible again | Full deduction restored |
If you purchased a rental property between October 2021 and March 2024 and weren't claiming interest during the restriction period, you can now claim the full amount again. There's no catch-up for the years where deductions were restricted, those are simply lost (IRD).
New builds exception
New builds (defined by their Code Compliance Certificate date) were always exempt from the interest deductibility restrictions. They retained full deductibility throughout the 2021 to 2024 period. Under the current rules, this distinction no longer matters because all residential rental interest is deductible again (IRD).
Ring-fencing rental losses: what it means for you
Since 1 April 2019, residential rental losses are ring-fenced. This means if your rental expenses exceed your rental income (creating a loss), you cannot use that loss to reduce tax on your other income like salary or wages (IRD).
Instead, the loss carries forward and can only be offset against:
- Rental income from the same or other residential properties in future years
- Gains from selling residential property that are taxable (for example, under the bright-line test)
Worked example: ring-fenced loss
| Item | Amount |
|---|---|
| Rental income | $31,200 |
| Total rental expenses (including interest) | $38,000 |
| Rental loss | -$6,800 |
| Can this offset your $80,000 salary? | No. The loss is ring-fenced. |
| What happens to the $6,800 loss? | Carried forward to offset future rental profits |
Before ring-fencing, a landlord with an $80,000 salary and a $6,800 rental loss would have paid tax on $73,200 instead of $80,000, saving about $2,244 in tax at the 33% marginal rate. That tax benefit no longer exists for residential property (IRD).
Ring-fencing applies to residential rental property only. Commercial property is not affected.
Bright-line test: when property sales are taxed
The bright-line test determines whether the profit from selling a residential property is taxable. If you sell within the bright-line period, the gain is treated as income and taxed at your marginal rate (IRD).
Current bright-line periods (from 1 July 2024)
| Property type | Bright-line period |
|---|---|
| New builds | 2 years |
| Existing residential property | 2 years |
The bright-line period was reduced to 2 years for all residential property from 1 July 2024 (IRD). Previously, it was 10 years for existing properties and 5 years for new builds (from March 2021 to June 2024).
How the bright-line test works
The clock starts on the date you acquire the property (usually the date the title transfers to you) and stops on the date you enter into an agreement to sell. If that period is less than 2 years, any gain is taxable (IRD).
Exemptions from the bright-line test:
- Your main home (the property you live in most of the time)
- Property inherited from a deceased estate
- Property transferred as part of a relationship property settlement
If the bright-line test applies, your taxable gain is the sale price minus the original cost, minus any capital improvements, minus selling costs. You can't deduct the land value portion separately. The full gain is taxed at your marginal rate (IRD).
Worked example: bright-line
You bought a rental property for $650,000 in June 2025 and sold it for $720,000 in March 2026 (9 months later). You spent $15,000 on capital improvements and $20,000 on selling costs (agent fees, legal fees).
| Item | Amount |
|---|---|
| Sale price | $720,000 |
| Purchase price | -$650,000 |
| Capital improvements | -$15,000 |
| Selling costs | -$20,000 |
| Taxable gain | $35,000 |
| Tax at 33% marginal rate | $11,550 |
If you'd held the property for more than 2 years, this $35,000 gain would not be taxable under the bright-line test.
Worked example: tax on a $600/week rental property
Here's a detailed tax calculation for a typical NZ rental property, assuming the landlord earns $85,000 in salary and has a mortgage on the rental (IRD rates, 2025-26).
Property details
| Item | Amount |
|---|---|
| Weekly rent | $600 |
| Annual rent | $31,200 |
| Property value | $750,000 |
| Mortgage on rental property | $500,000 |
| Mortgage interest rate | 5.50% |
| Annual mortgage interest | $27,500 |
Annual rental expenses
| Expense | Annual cost |
|---|---|
| Mortgage interest | $27,500 |
| Council rates | $3,200 |
| Insurance (building + landlord) | $2,100 |
| Property management (8% of rent) | $2,496 |
| Repairs and maintenance | $2,000 |
| Accounting fees | $600 |
| Depreciation on chattels | $800 |
| Other (travel, advertising) | $400 |
| Total expenses | $39,096 |
Tax calculation
| Item | Amount |
|---|---|
| Gross rental income | $31,200 |
| Total expenses | -$39,096 |
| Net rental income (loss) | -$7,896 |
| Ring-fenced? | Yes. Cannot offset against $85,000 salary. |
| Tax on rental income this year | $0 |
| Loss carried forward | $7,896 |
In this example, the landlord has a rental loss of $7,896 after expenses. This is common in the early years of a mortgage when interest costs are high relative to rent. The loss carries forward and offsets future rental profits.
What happens as the mortgage reduces?
Over time, as you pay down the mortgage and rents increase, the property moves from a loss to a profit. Here's a simplified projection:
| Year | Annual rent | Interest cost | Other expenses | Net income | Tax at 33% |
|---|---|---|---|---|---|
| Year 1 | $31,200 | $27,500 | $11,596 | -$7,896 | $0 (loss carried forward) |
| Year 3 | $33,800 | $25,800 | $12,000 | -$4,000 | $0 (loss carried forward) |
| Year 5 | $36,700 | $23,900 | $12,400 | $400 | $0 (offset by carried losses) |
| Year 7 | $39,800 | $21,800 | $12,800 | $5,200 | $1,716 |
| Year 10 | $44,700 | $18,500 | $13,400 | $12,800 | $4,224 |
These projections assume 4% annual rent growth and a reducing mortgage balance. The actual results depend on your specific interest rate, rent increases, and expense levels.
Record keeping and filing requirements
If you earn rental income, you need to (IRD):
Keep records for at least 7 years, including:
- Tenancy agreements
- Rent received (bank statements, ledger)
- All expense receipts and invoices
- Mortgage interest statements
- Insurance policies and premium receipts
- Council rates notices
- Property management statements
- Records of any capital improvements
File an IR3 tax return each year declaring your rental income and expenses. The deadline is 7 July (or 31 March the following year if you have a tax agent). See our guide to filing a tax return for the full process.
Pay provisional tax if your residual income tax exceeds $5,000 for the year. This is common once your rental property becomes profitable and your combined income pushes your tax bill up.
Separate personal and rental finances. IRD expects you to clearly distinguish between personal expenses and rental expenses. A dedicated bank account for rental income and expenses makes this straightforward.
Common questions
How is rental income taxed in New Zealand?
Rental income is added to your other income and taxed at your marginal rate (10.5% to 39%). You calculate your net rental income by subtracting deductible expenses (interest, rates, insurance, management fees, repairs, etc.) from gross rent received. The net amount is what's taxed (IRD).
Can I deduct mortgage interest on my rental property?
Yes. From 1 April 2024, mortgage interest on residential rental properties is fully deductible against rental income. This was restored after a period (2021 to 2024) where deductibility was restricted or removed. The full interest amount on your rental property mortgage is now a deductible expense (IRD).
What is ring-fencing of rental losses?
Ring-fencing means that if your rental expenses exceed your rental income, the resulting loss can only be carried forward and offset against future rental income or taxable property gains. You can't use a rental loss to reduce tax on your salary or other non-rental income. This has been in effect since 1 April 2019 (IRD).
What is the bright-line test for property?
The bright-line test taxes the capital gain on residential property sold within 2 years of purchase (as of 1 July 2024). If you sell within 2 years, the profit is treated as income and taxed at your marginal rate. Your main home is exempt. The 2-year period runs from title transfer on purchase to the date you agree to sell (IRD).
What expenses can I claim on a rental property?
Deductible expenses include mortgage interest, council rates, insurance, property management fees, repairs and maintenance, body corporate fees, accounting fees, advertising, travel for property inspections, and depreciation on chattels (furniture, appliances). Capital improvements (renovations, additions) are not deductible but add to the cost base of the property (IRD).
Do I need to file a tax return if I have rental income?
Yes. If you receive rental income, you need to file an IR3 individual tax return. IRD's automatic assessment doesn't cover rental income because it requires you to calculate your net rental income after expenses. The deadline is 7 July, or 31 March the following year with a tax agent (IRD).
How much tax will I pay on a $600/week rental?
On $31,200 per year of gross rent, your tax depends on your deductible expenses and your marginal tax rate. If you have $39,000 in expenses (including a large mortgage), you'll have a loss and pay no tax on the rental that year. If your expenses are $20,000, your net rental income is $11,200, and the tax at a 33% marginal rate would be $3,696 (IRD).
What happens to rental losses I can't use?
Ring-fenced rental losses carry forward indefinitely and offset future rental income or taxable gains from residential property sales. They don't expire. If you have a $7,896 loss in year one and a $5,000 profit in year two, the loss offsets the profit, leaving $2,896 still to carry forward (IRD).
Is Airbnb income taxed differently from long-term rental income?
No. Short-stay accommodation income (Airbnb, Bookabach, etc.) is taxable in the same way as long-term rental income. It's declared as rental income in your IR3 and you can deduct related expenses. However, if the property is also your home, you need to apportion expenses between personal use and rental use. The bright-line test applies to short-stay properties in the same way (IRD).
Do I need to pay provisional tax as a landlord?
If your total residual income tax for the year exceeds $5,000 (from all sources including rental), you'll need to pay provisional tax the following year. This means making estimated tax payments in three instalments during the year rather than a lump sum at the end. This commonly applies once your rental property becomes profitable and your combined income is high enough (IRD).
