Do I have to pay tax on my rental income?

Yes. If you earn rental income in New Zealand you must include it in an income tax return each year, usually an IR3 for an individual. You pay tax on the net rental income: the rent you received, less the expenses you are allowed to deduct. Even if your rental made a loss, it generally still needs to be returned.

What expenses can I claim?

You can deduct the costs of earning the rental income. Common ones include rates, insurance, property management fees, repairs and maintenance, accounting fees, and (subject to the interest rules below) mortgage interest. You cannot deduct the cost of the building itself or capital improvements, though you can usually depreciate chattels like carpets, curtains and appliances.

Can I claim my mortgage interest?

For most residential landlords, interest is fully deductible again from 1 April 2025, after several years of the deduction being phased down.

What is ring-fencing of rental losses?

Residential rental losses are generally "ring-fenced", you cannot offset them against your other income like salary. Instead the loss carries forward to reduce future rental income. We apply this automatically when we prepare your return.

The bright-line test, briefly

The bright-line test can tax the gain when you sell a residential property within a set period of buying it. The period and rules have changed over time. If you bought or sold during the year, we review whether it applies as part of your return.

When is my return due?

The tax year runs 1 April to 31 March. If you file yourself, the deadline is usually 7 July. A registered tax agent like Playdough gets an extension of time beyond that, one of the quiet benefits of having us file for you.

What does filing actually involve?

In practice: gather your documents, work out the rental result, complete the rental schedule and the income tax return, and file it with IRD. That is exactly what Nestie does for you, for a fixed price, with a draft you approve before anything is filed.
