Rental-property & investor tax

Rental income and what's deductible

Rent you receive is taxable income, and it goes on your return alongside your other income. Against it you can claim the costs of earning that rental income, which is where a good return puts real money back in your pocket.

Commonly deductible costs on a residential rental include:

• Rates and insurance on the property
• Repairs and maintenance (fixing what's there, as opposed to improving it)
• Property management fees and letting fees
• Accounting and certain professional fees
• Mortgage interest, subject to the deductibility rules below
• Depreciation on chattels (but not the building itself)

The important distinction is repairs versus improvements. Replacing a broken oven with a like-for-like model is a deductible repair; renovating the kitchen is a capital improvement that's added to the property's cost, not claimed in the year. Getting that line right is one of the most common things we tidy up on rental returns. This is general information, not personalised advice; confirm your situation with us or check ird.govt.nz.

Ring-fencing of rental losses

This is the rule that surprises landlords who bought expecting a tax-deductible loss. Since the rules changed, residential rental losses are ring-fenced. That means if your rental costs exceed your rental income in a year, you generally cannot use that loss to reduce the tax on your salary or other income.

Instead, the loss is parked and carried forward, to be used against future rental income from your portfolio. So a loss isn't lost, but it's deferred. It sits there until your rentals are profitable, then it soaks up some of that profit before tax applies.

The practical effect: negatively-geared residential property no longer shelters your day-job income. Many investors only discover this when their accountant explains why the refund they expected didn't appear. We map your ring-fenced losses correctly and track the carry-forward year to year. See our rental loss ring-fencing guide and the worked example for the numbers.

The bright-line test on sale

New Zealand doesn't have a general capital gains tax, but the bright-line test acts like one for residential property sold within a set window of buying it. If you sell inside the bright-line period, the gain is taxable as income.

Two things make this trickier than it sounds:

• The period has changed over the years. Properties bought at different times can fall under different bright-line windows, so your purchase date determines which rules apply to you.
• The main-home exclusion generally takes your own home out of the test, subject to conditions about how you used it.

Because the date you acquired the property drives everything, the single most valuable thing we do here is establish the correct dates and the right version of the rules before you sell, not after. Selling a day on the wrong side of the line can be the difference between a tax-free gain and a taxable one. Our bright-line test explained guide walks through it, and we'll always recommend getting advice before you list, not after settlement.

Interest deductibility rules

Mortgage interest is usually a landlord's biggest cost, so whether you can deduct it matters enormously. This is an area that has changed direction more than once in recent years, with interest deductibility on residential rentals first limited and phased down, then restored.

Because the rules have moved, the safe approach is to confirm the current position for the income year you're filing rather than assume it's the same as a few years ago. The treatment can also differ depending on when the property was acquired and whether it's a new build, which has had its own concessions.

• Interest on borrowing used to buy or improve a rental is the relevant cost
• The deductible proportion has varied by year and by property type
• New builds have at times had more favourable treatment

We apply the rules that actually apply to your property for the year in question, so your interest claim is both maximised and correct. See interest deductibility on NZ rentals for the current detail. This is general information; confirm your situation with us or check ird.govt.nz.

Chattels and depreciation

You can't claim depreciation on the building itself, but you can on the chattels inside it, the removable items that wear out. For many landlords this is a quietly valuable deduction that's often understated or missed entirely.

Chattels that are typically depreciable include:

• Carpets, curtains, and blinds
• Whiteware: oven, dishwasher, heat pump, rangehood
• Light fittings and certain fixtures
• Furniture in a furnished rental

The trick is doing a proper chattels valuation at purchase, splitting the price you paid between the land, the building, and the chattels, so each component gets the right treatment. A good split front-loads legitimate depreciation deductions in the early years of ownership.

Bear in mind depreciation recovery: if you later sell chattels for more than their depreciated value, some of the depreciation you claimed can be clawed back as income. We set the valuation up properly at the start and account for recovery correctly on sale, so there are no nasty surprises. See claiming chattels depreciation for more.

Airbnb and short-stay income

Short-stay accommodation, such as listing a property or a room on Airbnb, is taxed differently from a standard long-term rental, and it catches a lot of hosts out. The income is taxable, the expense rules are more nuanced, and crucially GST can come into play.

Two things to watch:

• Mixed private and rental use. If you rent out a room or use the place yourself part of the year, you can only claim the costs that relate to the short-stay use, apportioned fairly.
• GST. Short-stay accommodation is a taxable activity, so once your total taxable turnover crosses $60,000, GST registration becomes compulsory, and selling a GST-registered property later has its own consequences.

This is an area where getting it wrong is easy and expensive, particularly the GST side, where registering can pull the property itself into the GST net. We work out the income tax and the GST position together so you see the full picture before you list. Our tax on Airbnb income guide covers it in depth.

Fixed-fee pricing

Rental and investor returns are priced as a fixed fee, set after a free review. The cost depends on how many properties you hold, whether there are sales or chattels valuations to handle, and how tidy your records are, and we agree it before any work starts.

• Single rental return, fixed fee
• Multi-property portfolio with loss tracking and apportionment
• Bright-line and chattels work on purchase or sale
• Combined packages covering your rental and your personal IR3

No hourly meter, and no surprise add-ons for the parts of property tax that always turn out to be involved.

This page is general information, not personalised tax advice. Property rules, especially bright-line and interest deductibility, have changed repeatedly, so confirm your situation with us or check ird.govt.nz. In plain English: residential rental losses are ring-fenced and carried forward, the bright-line test can tax a sale, and your purchase date and chattels split decide a lot, so it pays to get the return right.
