The new tax rules – will you pay more tax?
the new Tax rules, provisional tax and cash flow. How the changes could impact you.
The new tax rules recently introduced by the Government will mean more tax to pay for many taxpayers. The impact of these changes needs to be understood and considered when planning your cash flow.
What changes?
Since I last updated you about the tax changes commencing from 1 April 2021, there has been another raft of changes to our tax legislation. Some of these new tax rules were anticipated, but some were certainly surprising, and could be significant.
Now we are in the 2022 income year, we not only have the higher income tax rate, which is supported by higher FBT and RWT rates, we still have the residential rental loss tax ring-fencing carrying forward and applying in new and challenging situations, and the complicated mixed-use asset rules to really mystify the tax landscape.
We now also have an extended Brightline Test, with changes to the main home exemption. And the removal of an ability to deduct interest by owners of residential rental properties. The changes can apply retrospectively and are bundled with transitional measures to guarantee a continuously changing landscape over the next five years.
You’ve probably got the point – we need to talk.
However, in the meantime, I wanted to give you a high-level overview of things you should be thinking about upfront.
Why?
Because you may need to pay more tax. And that is going to impact on your cashflow.
What are the new tax rules, and how will they affect my tax liability?
New personal tax rate
A new 39% income tax rate for individuals earning income over $180,000. Previously New Zealand’s top individual income tax rate was 33%. If you are in this income bracket and paying provisional tax, we need to increase your provisional tax payments to take into account the higher tax rate.
Do you own residential rental properties? Your tax liability is likely to increase:
- Removal of interest deductibility.
- When you own a residential rental property, as with any business or investment, you will incur a number of costs. Usually, we can take these costs or expenses off your income, and you pay tax on your net profit.
- However, these new rules, in short, mean we won’t be able to treat the interest on your mortgage for your rental property as an expense. You may end up paying tax on the rental income, without deducting many expenses at all.
- If you have a residential rental property, these rules are likely to increase your tax bill. We need to factor this into your cash flow and tax planning.
- Residential tax loss ring-fencing. These rules came into force for the 2020 income year, but can still catch people by surprise.
- These rules mean that if you make a loss on your residential rental property, you cannot offset that loss against other income.
- For example, we used to offset the loss against your salary income, which reduced your overall taxable income and your overall tax bill. We can no longer do this, and many taxpayers have larger tax liabilities as a result.

Brightline changes
The extended Brightline Rules mean that the sale of a property within ten years could be taxed.
Although the Brightline Tax may be a tax on capital gains, at its heart it is an income tax. This means you must pay the tax at your income tax rate and include it in your tax liability for the year. This can create a raft of surprises for provisional tax… particularly now the highest personal income tax rate is 39%. If this could impact you, we need to put a plan in place to address this issue.
The changes to the main home exemption could also mean more homes are taxed on sale. Although your main home continues to be exempt from the Brightline Test, there is a difference in the way you classify it – particularly if there are periods where you are not living in the house. Are you building a house? Are you being seconded elsewhere? Taking an extended break? Not living in your house whilst completing renovations? These scenarios could trigger a taxable period of ownership – even if it is your main home.
Results Better than expected?
There are also non-tax influences that impact on a business profit, and therefore tax liability. We have had record low interest rates and, in some circumstances, higher levels of income. We have seen many sectors out-perform earlier expectations, and some businesses have had record profits. These higher profits need to be factored into provisional tax liability calculations. Easier said than done without a crystal ball I know.

When?
This tax is due for your 2022 income year. If you are paying tax on your terminal tax date, this is likely to be due 7 April 2023 – if you are on our IRD Agency List and have an extension of time.
However, the tax may be due earlier if you fall into the provisional taxpayer criteria:
- If you are a provisional taxpayer, we need to factor these tax changes into your provisional tax payments.
- If you are not a provisional taxpayer, you need to understand provisional tax as the changes may mean you become a provisional taxpayer – because you have more tax to pay.
What is provisional tax?
Over the next 12 months many taxpayers that have never been provisional taxpayers before are likely to find themselves liable as provisional taxpayers. This is a direct result of the tax changes that mean they will have more tax to pay. So, what do you need to know about provisional tax?
- It is a pre-payment of your income tax liability for the year.
- If you are over the provisional tax threshold, you must pay provisional tax, this is not an optional payment arrangement.
- You will generally have to pay provisional tax for the 2022 income year if you had to pay more than $5,000 tax for the 2021 income year. This applies for all taxpayers with a NZ tax liability – i.e. even if you don’t live here you could still be a provisional taxpayer.
- There are several methods for calculating your provisional tax liability, and penalties if you get it wrong.
Got it wrong?
Inadvertently become a provisional taxpayer? Find yourself with a large tax bill? Talk to us now, we have options to minimise the penalties and interest if you act fast.
