Review your tax before IRD unexpectedly knocks
By Matt Rama, TMNZ Chief Commercial Officer, Tax Lawyer and Chartered Accountant.
Inland Revenue (IRD) is intensifying its focus on tax compliance, after a few years of leniency to account for the impact of COVID on businesses.
With an extra $116 million in funding, Inland Revenue is stepping up its focus on compliance and auditing tax paying businesses to make sure everyone is “Getting it Right” and is up to date on their tax obligations. IRD expects to recover around $800 million in unpaid tax over the next four years.
Recent media reports that IRD inspectors are making unannounced visits to businesses to review payroll and GST records are also correct. While the so-called hidden cash economy is a target, all businesses need to pay heed to the crackdown on compliance and the technical application of tax rules and regulations.
The importance of voluntary disclosure
Instead of waiting for an unexpected audit, businesses should proactively review their tax compliance. Consulting a tax advisor and making a voluntary disclosure can be beneficial, as IRD offers leniency in penalties for those who come forward.
Shortfall penalties, which can range from 20% for minor mistakes to 150% for tax evasion, may be reduced or waived entirely for voluntary disclosures. A voluntary disclosure takes a lot of heat out of the situation. In contrast, if IRD discovers non-compliance through an audit, businesses could face severe financial penalties or even legal consequences, including imprisonment for serious tax evasion cases.
IRD’s compliance efforts and liquidation trends
Post-COVID, IRD initially adopted a more relaxed approach but has now increased its enforcement. Historically, good businesses struggling due to temporary economic hardship may qualify for instalment plans, but IRD is also targeting “zombie companies” that may have survived the COVID period with government assistance but failed to maintain proper tax practices and may not be viable or sustainable going forward. These businesses may face liquidation to prevent further financial damage.
The number of firms put into liquidation by the IRD has increased 56% to 849 year to date in 2025, up from 549 for the same period in 2024.
From my perspective, putting a company into liquidation is often the right thing to do. An early liquidation due to unpaid taxes and virtual insolvency is better than letting a failing business carry on, doing more financial damage to staff, customers and suppliers.
Inland Revenue appears to be focused on payroll tax compliance, GST, Non-Resident Withholding Tax (NRWT) obligations and industries with a high risk of underreporting income.
Payroll and GST compliance is a particular focus as these are ‘pass-through’ taxes where the business has no right to hold onto the funds. IRD takes a dim view of businesses that knowingly have a GST or payroll liability as these are technically and legally not theirs to keep . That doesn’t mean you shouldn’t pay or delay paying company income tax, but for GST, you’ve already collected the tax so you should have the funds to pay IRD and for PAYE, there are much harsher penalties.
The area of NRWT impacts fewer taxpayers but is also where IRD is finding substantial discrepancies. In a nutshell, NRWT applies to businesses that have borrowed from offshore lenders and are making interest payments to these foreign lenders. These payments generally carry a 15% (or possibly a reduced rate due to treaty relief) withholding tax to IRD. NRWT (at different rates) can also apply to dividends paid to overseas shareholders. Not filing a NRWT return is, let’s just say, problematic for the local borrower.
Inland Revenue is making changes to legislation to help get some of these businesses back on track where they have borrowed from unrelated overseas lenders by allowing them to retrospectively register for ‘Approved Issuer Levy’ which allows the NZ business paying the interest to effectively pay a lower rate.
Take action now
To avoid penalties and ensure compliance, businesses should:
- Conduct a thorough review of all tax obligations.
- Consult with your tax advisor or accountant.
- Make a voluntary disclosure if necessary.
Another feature of the current crackdown is the timeframe. In the past IRD may have only cast back a few years, but we are seeing reassessments going back to 2013 or even 2010 in some cases.
Businesses come to us in shock and say they have big back taxes to pay, plus IRD interest and penalties.
If you have funds and can pay the old tax, plus interest and penalties, that’s ok. But for those that don’t have the funds or want a cheaper option, the best method is to use the services of an IRD-approved tax pool, like TMNZ.
These are funds already paid to IRD for each tax payment date going back, in our case, to 2008. These tax payments are available to businesses to purchase from TMNZ at a significant discount to the IRD penalties and interest.
Any business, providing there is no deliberate tax evasion, can access tax pools. Even companies that owe NRWT and haven’t filed a previous return may be able to use tax pools to pay owed NRWT – an application for IRD discretion to permit the use of tax pooling can be made in the case of a voluntary disclosure –. In fact, you can use TMNZ to fix your reassessed tax for any tax type not just income tax.
How does it work? A business buys backdated tax from the tax pool and instead of paying the IRD interest rate it pays a rate that is always lower than the IRD interest rate. Late payment penalties and the use of money interest will all reverse out if you buy the backdated tax from the pool and get it transferred to your IRD tax account within the stipulated timeframes, which is within 60 days after IRD issues you the reassessment notice (this date is shown on the reassessment notice).
I have been asked that if Inland Revenue is expecting $800 million of reassessments, do you have enough tax payments to cover all of that? Frankly, across all tax pools there is not $800 million available for reassessments. There’s more than enough for current periods (tax years in which tax returns are still able to be filed), because the amount of tax payments steps up exponentially (like in the billions). But because there’s some risk sitting on unrequired funds we don’t hold infinite amounts of tax in those prior periods. It is first come, first served. It’s like land. There’s a limited supply.
As there are people who are proactive, make voluntary disclosures and get the backdated tax first, there’s less for the next person to come along who might get audited by Inland Revenue in two years’ time.
Being proactive can prevent financial and legal repercussions while demonstrating good faith to tax authorities. Stay compliant and avoid the risk of unexpected audits.

Missed your latest provisional tax payment? How you can find relief
Forgot to pay your provisional tax? Or maybe cashflow was tight and you couldn’t quite make the payment work? Either way, you’re not alone. And more importantly, you’re not out of options.
If you own a business, you know provisional tax and its inflexibility all too well. Miss a due date and the penalties and interest start piling up fast. But here’s the thing – there’s relief available, with TMNZ.
Let us show you how we can help.
What happens when you miss that payment?
When you pay provisional tax late or don’t pay enough by the due date, Inland Revenue (IRD) charges penalties and interest on your unpaid amount:
- A 1% late payment penalty (LPP) kicks in the day after the due date
- An additional 4% penalty hits seven days later – and that’s on top of any existing penalties
- 9.89% UOMI (use of money interest) gets charged daily from the day after the due date until you’ve paid everything, including penalties and interest.
The costs add up quickly. But there’s a way around this.
Enter TMNZ – your relief option
TMNZ pioneered tax pooling – a world-first, and IRD-approved solution. Here’s how it works.
We pool provisional tax payments from multiple businesses in an account we hold as a registered tax pooling intermediary. When one business needs more time to pay, another business’s overpayment covers them. Business helping business.
Because we can backpay your unpaid tax, IRD no longer sees it as a ‘late payment.’ Which means you dodge those penalties and fees entirely.
Whether you simply forgot to pay or cashflow got tight, TMNZ gives you breathing room. You can make a one-off payment when it suits you, or set up regular instalments – giving you up to 13 months to pay your provisional tax.
Missed your terminal tax date too? We can still help slash interest costs and wipe out late payment penalties.
The real deal
TMNZ lets you pay when it actually works for your business. There is some interest to pay – but it’s much lower than IRD’s late payment interest or what you’d pay on business overdrafts or unsecured loans. And tax pooling with TMNZ eliminates those late payment penalties entirely.
All you need to do is tell us how much tax is due and when or how you’d like to pay it. We handle the rest and notify Inland Revenue of your arrangement. Simple.
Take control of your tax payments
Whether you forgot to pay or couldn’t make the payment work with your cashflow, you’ve got options. TMNZ can eliminate those late payment penalties and give you the payment flexibility your business needs.
Contact your accountant or tax agent and let them know you want to use TMNZ’s tax pooling product for your missed or underpaid provisional tax. Or get in touch with us directly to explore your options.
Don’t let a missed payment throw your business off track. With TMNZ, you can navigate tax season with confidence and keep your cashflow working for you.

TMNZ: The ultimate cashflow flexibility tool for your business
In tough economic times, it can be hard for businesses to stay on top of cashflow and juggle their tax liabilities. For companies and sole traders dealing with fluctuating cashflow and provisional tax headaches, there’s an easier way to manage your obligations—tax pooling.
Did you know TMNZ’s tax pool can help you manage your tax by matching your cashflow forecasts with your provisional tax payments? And you can use tax pool deposits as an alternative funding source when cashflow is tight.
How we can help
TMNZ is an Inland Revenue (IR)-approved tax pooling provider, meaning you can use us to pay income tax on your behalf at a time that suits you. We offer greater flexibility over how and when you pay provisional tax.
First, you’ll need to think about your cashflow forecast. If you’re unsure how to put one together, read our cashflow management guide.
Once you’ve got your cashflow projection, we can work together to figure out the best time to pay your provisional tax. From there, all you need to do is tell us your tax amount owed, the date it is due, and how you would like to pay.
When your tax bill arrives, we’ll transfer the amount required to IR on your behalf as a time-stamped payment. IR will treat your tax as if it was paid on time, eliminating the risk of being charged interest or late payment fees. Simple.
A working capital solution
TMNZ’s payments to IR mean you can keep money in your business and use it at the times of the year you’ll need it most. You can top up your payments later into our tax pool at any time.
Tax pooling is a perfect solution for businesses worried about future cashflow and looming obligations. By partnering up with us, you’ll have total control over your tax bill, rather than working around IR’s strict deadlines.
With no more late fees and interest charges from IR to think about, you can get on with running your business. There will be no need to scrape together funds in the middle of holidays or quiet periods to meet IR’s deadlines.
TMNZ can also save you money by avoiding penalties and interest charges if you’ve missed or underpaid tax. We charge much lower interest rates than the penalties imposed by IR if you’re overdue.
We’re a line of credit
Another amazing TMNZ feature is that we can be a line of credit for your business.
If you’ve deposited funds into our tax pool but find yourself short on cash, you can withdraw that money whenever you want to use it as working capital.
If you’ve paid provisional tax into our pool, you’ll have access to a working capital facility up to the value of your deposit. This provides even more flexibility for you and your team to get through a cash crunch and stay on top of debt management.
We can offer much cheaper interest rates than bank loans, overdrafts, or unsecured loans, meaning money withdrawn from our pool is better for you and your business, putting you in a stronger position at the end of the year.

How to manage cashflow over Christmas
Everyone loves the middle of summer and spending time with family and friends over Christmas, but it can be a challenging time of year for many small and medium-sized Kiwi businesses.
According to a poll conducted by the Employers and Manufacturers’ Association, more than half of businesses experience cashflow constraints between January and March.
It’s hardly surprising. The period after Christmas is traditionally slow for many companies, with people away enjoying their holidays. Consumers also tend to reduce spending after the expensive Christmas and New Year period.
Businesses can come under pressure for a number of reasons. Earnings will be down if companies shut over the break, while others will feel the pinch if they have paid bonuses before the end of the year.
Considering these facts, it’s understandable that many businesses struggle to manage cashflow and make provisional tax payments on 15 January every year.
Unfortunately, Inland Revenue (IR) doesn’t factor in these seasonal challenges. IR charges taxpayers 5.04% late payment penalties and 10.91% use of money interest (UOMI) if tax is not received on the due date (as at November 2024).
Your options for managing cashflow
What are the best options for businesses that want to manage cashflow and free-up money over the summer?
Tax pooling is IR-approved and can be used to defer provisional tax payments to a time that suits the taxpayer without incurring late payment penalties and UOMI.
This method is cheaper than using many traditional forms of finance. And tax pooling doesn’t affect existing lines of credit. Also, no credit checks or security are required.
The full amount of finance doesn’t need to be paid back if less tax is owed than first thought. The finance arrangement can be easily extended as well.
How tax pooling can help
Say you want to defer a $5,000 provisional tax payment for six months. You would pay TMNZ a one-off, tax-deductible interest amount and TMNZ would arrange the $5,000 provisional tax payment on your behalf.
The interest amount is based on the amount of tax financed and the period of maturity, so in this instance, it would be roughly $205.
The provisional tax payment is held in an IR account administered by the Guardian Trust. Guardian Trust instructs the IR to transfer the tax into your IR account when you repay the $5,000 principal in six months’ time.
The IR treats the $5,000 provisional tax as being paid on time once the transfer is processed. It’s that simple.

How TMNZ tech takes the pain out of tax
As New Zealand’s first ever tax pool, we’re proud of our long history of innovation. It’s at the heart of everything we do, and we’re always looking for new ways to simplify tax.
Technology has been at the forefront of our efforts, whether it’s rolling out new features for our customers, adding new functionality online, or partnering with forward-thinking digital platforms.
Recently, we’ve rolled out some amazing tools to help our customers and their accountants easily manage income tax.
Discover our top tech solutions to help you take the pain out of tax time, including tools to cut down on admin, share data between platforms, and get instant information on things like tax swaps.
Direct Inland Revenue Integration
TMNZ’s online dashboard is fully integrated with Inland Revenue (IR), meaning taxpayer information held by IR can be seamlessly shared on our platform, to make accountants lives easier.
In the past, accountants had to deal with multiple systems and spreadsheets to find accurate IR information. Integration means this admin work is no longer required.
Inland Revenue and TMNZ systems are directly connected so that key IR information is automatically populated on our dashboard. All relevant IR data, including Residual Income Tax figures, filing dates, and direct IR transactions appear on the TMNZ dashboard once you’ve logged in.
Thanks to IR integration, accountants can save time and reduce admin work. Direct IR integration also removes the risk of manual errors as clients populate information from one platform to another, making the process much more efficient.
IR information is fed into our calculator to help you determine your (or your client’s) tax position as quickly as possible.
Kathleen Payne, Partnerships Director at TMNZ, says:
“Following IR integration, all the data you need for your calculations goes straight onto our dashboard. All you have to do is put in the current year’s position that IR might not know yet, and everything is calculated without further data entry.”
If clients need any assistance with our direct IR integration, then TMNZ's friendly support team is on hand to help. And you can find out more about IR integration here.
Taxlab integration
Our systems are also fully integrated with Taxlab, the cloud-based tax software system designed specifically for New Zealand accountants.
Taxlab integration is easy to set up and use. Once you’ve completed the process, TMNZ transactions will appear on the Taxlab platform. Clients no longer need to use different systems to calculate their tax position.
“Accountants will get a complete picture of all TMNZ transactions sitting against their clients’ tax year,” Kathleen says.
Like IR integration, the setup couldn’t be simpler:
- log in to Taxlab, go to ‘Settings’, and add TMNZ as a connection
- you’ll then be directed to TMNZ to log in and confirm
- from there, you’ll be able to view TMNZ tax pooling information, including a full history of purchases, deposits, transfers, and tax payments.
Integration with Taxlab reduces the time and effort spent sharing information across the two platforms, giving tax agents even more time for their valuable client work.
Group Optimiser
If you’re a busy accountant in public practice looking to manage the tax year for groups of clients, TMNZ’s Group Optimiser tool is tailor-made for you.
This innovative feature enables accountants to calculate the position of several taxpayers and create multiple transactions at once.
Used alongside IR integration, Group Optimiser can make tax calculations even simpler.
Kathleen adds:
“Instead of having to prepare spreadsheets for each member in a group and then decide who has overpaid or underpaid tax, agents can use our calculator to enter a small amount of information. Then, at the click of a button, Group Optimiser calculates how to use the tax across the group in the most effective way.”
Group Optimser is ready and waiting on the TMNZ dashboard. All you need to do is log in.
Upcoming Deadlines
The Upcoming Deadlines function on the TMNZ dashboard is another of our top tech features.
For accountants managing several tax pooling clients, the Upcoming Deadlines feature can be used to track taxpayers ahead of key dates.
Offering total visibility over client tax positions as deadlines approach, the tool suggests prompts and actions to finalise the year.
“It also gives accountants a control list to work through their clients and ensure everything has been finalised,” Kathleen says. “It’s a workflow and control function and will remind advisers about everything they need to do for their clients.”
Automated Tax Swaps
TMNZ’s automated Tax Swaps is our latest dashboard feature, enabling clients to get instant quotes and process swaps below the threshold*.
Tax Swaps allow clients to even out their provisional tax payments if they have overpaid on one date and underpaid on another, saving on IR interest costs.
With our automated Tax Swap service, clients will benefit from faster, more efficient processing
The best part? The Tax Swap function is DIY.
“It’s a self-service system,” Kathleen explains. “If a client knows the swap they want to do, our system will automatically say, ‘Yes, you can do it, and this is the interest you’ll get’. You won’t have to interact with us at TMNZ. You can do-it-yourself.”
“It’s super efficient,” she adds. “Clients will have certainty of the outcome, they’ll know how much interest they’ll have to pay, or what they can earn, in an instant.
“At TMNZ, we’re all about flexibility, and empowering our customers to make decisions at a time that suits them.”
Automated Tax Swaps launched recently, following our pilot with TMNZ's Early Adopter community in April.
