The rules will not apply if the interest relates to income you earn in your main home (such as a
bed and breakfast business in your home). You will still be able to deduct some interest against
that income.
Tax reporting in New Zealand
If you are not a provisional taxpayer (discussed below) you will need to complete and file a
rental income schedule (IR3R), along with any other required tax filings, and pay income tax on
an annual basis on the rental income.
If you are required to pay more than NZ$5,000 but less than NZ$60,000 of income tax at the end
of the tax year (such amount being your “residual income tax” or RIT) due to the derivation of
income that was not subject to withholding tax over the course of the year (such as rental
income), you will become a provisional taxpayer from the beginning of the following tax year
and, from that time, you will be required to pay provisional tax. If you pay the RIT (being less
than NZ$60,000) by the terminal tax date (being 7 February of the following tax year), no use of
money interest will be charged.
However, if you start your rental business and your RIT for the first tax year of business is
NZ$60,000 or more, then you will be treated as a new provisional taxpayer for that year (and not
from the beginning of the next tax year). If you expect your RIT will be at least NZ$60,000 in
your first tax year of business, you should pay provisional tax, most likely in one instalment but
possibly in one to three instalments (dependent on the start date of your business) for that tax
year to prevent use of money interest charges.
You must keep records to be able to calculate the income and expenses of your rental property
and for Inland Revenue to confirm your accounts.
Reporting tax – filing deadline
New Zealand’s tax year runs from 1 April to 31 March (although, with Inland Revenue approval,
in certain cases a person can have an income year that ends on a different date).
The income tax return filing deadline is 7 July following the end of the tax year. This means that
the income tax return relating to income generated between 1 April 2021 and 31 March 2022
has to be filed by 7 July 2022.
If you have a tax agent, you may have an extension of time to file up to 31 March of the following
tax year (meaning that the abovementioned deadline is extended from 7 July 2022 to up to 31
March 2023). The extension length issued to New Zealand tax agents can vary so you will need
to contact your tax agent to determine the relevant filing date.
