Rental Property Expenses Tax Deductible NZ

Yes, in New Zealand, many of the costs you incur running your rental property are indeed tax-deductible. If you’re wondering whether rental property expenses are tax deductible in NZ, the key principle is straightforward: if you spent the money to earn rental income, you can generally claim it as an expense.

This simple rule allows you to deduct expenses like council rates, insurance, and repairs, which in turn reduces your overall taxable income.

Your Guide To Rental Property Expenses In NZ

Getting your head around which rental costs you can claim is one of the most important jobs for any landlord. At its core, the logic from Inland Revenue is pretty simple: if a cost is a necessary part of earning rent, it’s usually deductible. It helps to think of your rental as a small business; the everyday costs of keeping it running are your business expenses.

This covers a whole host of common costs. The obvious ones that spring to mind are things like council rates, property insurance, and the fees you pay a property manager to look after the place for you. But it also includes the money you spend on general repairs and maintenance—all the little jobs required to keep the property in a liveable, tenant-friendly state.

Having a solid grasp of these expenses is also essential for accurately calculating rental returns and figuring out if your investment is truly performing as you’d hoped.

Of course, it’s not as simple as claiming every dollar you spend. The big distinction you need to make is between your day-to-day running costs (which are deductible now) and significant improvements that add value to the property. These are called capital improvements, and the tax rules treat them very differently.

Common Deductible vs Non-Deductible Rental Expenses At A Glance

To make this distinction clearer, here’s a quick-reference table that summarises some of the most common expenses landlords encounter.

Expense Category	Generally Deductible	Generally Not Deductible (Capital)	Notes
Property Management	Full cost of fees	–	Includes letting fees, inspection fees, etc.
Rates & Insurance	Council rates, house & contents insurance	–	Fully deductible for the rental period.
Repairs & Maintenance	Fixing a broken window, plumbing repairs	Adding a new deck, renovating a kitchen	Repairs restore an asset; improvements upgrade it.
Mortgage Costs	–	Principal loan repayments	Interest may be phased back in. See below.
Legal & Accounting	Fees for tenancy agreements, tax advice	Legal fees if over $10,000	–
Travel	Trips to inspect or do maintenance	–	Claimable, but must be for the rental, not a holiday.
Valuations	For obtaining insurance	For mortgage purposes	The purpose of the valuation is key.

This table is just a starting point, as the specific details of an expense can change how it’s treated.

Navigating the rules can feel a bit daunting, especially with all the recent law changes floating around. This guide is designed to walk you through everything, from the basic concepts to the nitty-gritty of what you can and can’t claim. Getting it right from the start means you’ll pay the right amount of tax—no more, no less.

The Golden Rule for Claiming Rental Expenses

When it comes to claiming expenses for your rental property, there’s one golden rule from Inland Revenue (IRD) you need to know. It’s actually pretty straightforward: you can only claim an expense if there’s a direct link—what the IRD calls a ‘nexus’—between what you spent and the income you earned from rent.

Think of it like this: your rental property is its own little business. Any cost you incur to keep that business running, like getting a plumber in to fix a leaky tap, is almost certainly deductible. On the other hand, you can’t claim your personal weekly grocery bill, because that has nothing to do with generating rent.

This simple idea is the key to figuring out what you can and can’t claim. It also helps us separate two very different types of spending.

Running Costs vs. Big Improvements

Getting this next part right is crucial. You need to know the difference between an immediate running cost and a long-term investment.

• Running Costs (Revenue Expenses): These are the everyday expenses that keep your property in good shape. We’re talking about things like fixing a fence, repainting a room to freshen it up, or replacing a broken window latch. You can claim 100% of these costs in the same year you pay for them.
• Big Improvements (Capital Expenses): These are costs that go beyond a simple repair and actually improve the property or add something new. Think adding a deck, putting in a brand new kitchen, or building a garage. These aren’t immediately claimable against your rental income.

Practical example: Replacing a single broken fence paling is a repair (a running cost). Replacing the entire fence with a modern, more durable one is an improvement (a capital expense).

Once you’ve got your head around this distinction, you’ll find it much easier to decide where each expense fits. But if you’re ever scratching your head wondering if a new heat pump is a repair or an improvement, getting a bit of advice from an accountant can save you a world of hassle later on.

A Practical Checklist Of Claimable Expenses

We’ve covered the basics of running costs versus capital improvements. Now for the really useful bit: a practical list of what rental property expenses are tax deductible in NZ. Think of this as your go-to checklist to make sure you’re not leaving money on the table when tax time rolls around.

Common Deductible Expenses

These are the regular, day-to-day costs that come with being a landlord. For the most part, you can claim these in full in the same year you incur them.

• Professional Fees: This covers the experts you hire to make your life easier. Think property manager fees, letting agent commissions, and the cost of your accountant sorting out your rental accounts.
• Rates and Insurance: Your annual council rates and the insurance premiums you pay to protect your investment are fully deductible.
• Repairs and Maintenance: This is a big one. It’s for the everyday fixes – patching a leaky roof, replacing a broken door handle, or calling in a plumber for a blocked drain. It’s crucial to know what counts as a repair versus an improvement. We dive much deeper into this in our guide on what repair and maintenance costs are tax deductible.
• Travel Costs: Popping over to inspect the property or do a bit of maintenance? You can claim the travel. You can either use the official mileage rate set by the IRD or claim a portion of your car’s actual running costs.

Other Important Deductions

Beyond the usual suspects, there are a few other expenses that can help chip away at your taxable income.

• Bank Fees and Charges: Any fees your bank charges on the mortgage or the account you use for rental income and expenses are claimable.
• Rubbish and Pest Control: Paying for the council rubbish collection or getting a professional in to deal with pests? Those are both deductible operating costs.
• Home Office Costs: If you’re a hands-on landlord managing the property yourself from a home office, you can claim a slice of your household expenses like power and internet. This needs to be carefully calculated based on the area of your home you use for this work.

Under New Zealand tax law, the Inland Revenue Department (IRD) allows deductions for expenses like repainting or fixing a hot water cylinder. One key thing to remember, though: you can only claim for the materials and what you pay contractors. You can’t claim for your own time or labour, no matter how many weekends you put in!

For more detailed information, the IRD’s official guidance on rental income is a helpful resource.

How Mortgage Interest Deductibility Works Now

The rules around claiming mortgage interest have caused a lot of headaches for landlords lately. Thankfully, things have become much clearer, and it’s good news for property investors. Interest is once again a major part of your deductible rental property expenses in NZ.

For a few years, the ability to claim interest costs was being phased out, which meant higher tax bills for many. The government has now walked those rules back. As of 1 April 2024, you can claim interest deductions on your residential rental properties again, no matter when you bought the property or took out the loan.

This is a big change that simplifies things immensely.

What This Means for Your Tax Bill

So, what does this actually look like in your tax return? Let’s break it down with a simple example.

Imagine your annual mortgage interest comes to $20,000. Under the old rules, you might have only been able to claim a small fraction of that, or maybe nothing at all.

Now, for the 2024-2025 tax year, you can claim 80% of that interest. So, your claimable interest expense is $16,000 ($20,000 x 80%). The plan is to restore this to a full 100% deduction from the 2025-2026 tax year. This directly lowers your taxable rental income, which means less tax to pay.

Even with these positive changes, it’s easy to feel a bit lost. If you want to be sure you’re claiming everything correctly and getting the most out of your investment, it pays to get some expert help.

How to Handle Expenses for a Mixed-Use Property

It’s pretty common for a property to be used for more than just earning rent. Maybe you rent out your family bach for a few months of the year, or perhaps you’ve got a boarder in a spare room. This is what we call a “mixed-use” property.

When this happens, you can’t just claim 100% of your expenses. You have to apportion them – a fancy word for splitting the costs between your private use and the income-earning rental use.

You can only claim the portion of an expense that directly relates to the rental. Getting this right is a non-negotiable part of claiming rental property expenses tax deductible in NZ. Inland Revenue (IRD) will expect you to use a fair and reasonable calculation.

So, How Do I Apportion My Expenses?

Most landlords use one of two straightforward methods: floor area or time.

• By Floor Area: This is the go-to method if you’re renting out a room in the house you live in. For example, your tenant’s bedroom is 15 square metres and your house is 150 square metres total. You can generally claim 10% (15/150) of shared household costs like your rates, insurance, and any eligible mortgage interest.
• By Time: This works perfectly for a holiday home. For example, you rent out your bach for 90 days and use it yourself for 30 days. The property was available for rent or rented for 75% of the time it was used (90 days / 120 total days). You can claim 75% of the relevant expenses.

Think of it like this: you’re drawing a clear line in the sand between what’s personal and what’s business. Correctly apportioning costs keeps you on the right side of the IRD and makes sure you’re not claiming more than you’re entitled to.

This same logic applies to assets inside the property, like furniture or appliances. For a much closer look at how this works for assets that lose value over time, it’s worth reading our guide on understanding depreciation in New Zealand.

Keeping Good Records and Getting Expert Advice

Knowing what you can and can’t claim is one thing, but being able to prove it to Inland Revenue (IRD) is another game entirely. Think of your record-keeping as the foundation of your tax return – if it’s shaky, the whole thing could come tumbling down.

The simplest first step? Open a separate bank account just for your rental property. This keeps everything clean and makes tracking income and expenses a breeze, avoiding a messy mix-up with your personal spending. From there, it’s about holding onto the evidence.

Your Must-Have Records Checklist

• Receipts and Invoices: Every single one. Whether it’s a major invoice from a plumber or a small receipt for a can of paint, keep a digital or physical copy.
• Bank Statements: These act as your financial timeline, backing up the transactions for the property.
• Tenancy Agreements: These documents are your proof of who was living in the property, for how long, and how much rent they were paying.
• Travel Logbook: If you’re claiming travel costs, this is non-negotiable. You need to log the date, distance, and reason for every single trip related to the property.

With the top marginal tax rate sitting at 39%, getting your deductions right can make a huge difference to your bottom line. Missing out on small, legitimate claims—like a portion of your home office costs or those quick trips to the property for an inspection—really does add up over the year. It’s well worth getting a handle on how to properly calculate your rental accounting costs in NZ to ensure you’re not leaving money on the table.

While this guide gives you a solid overview, tax law has its twists and turns. Personalised advice is the only way to be certain you’re maximising every legal deduction and staying on the right side of the IRD.
