How to manage business cashflow over the seasonal period
Summer’s here. A time for family, friends, and well-earned downtime. But for many small and medium-sized Kiwi businesses, it’s also one of the toughest periods for cashflow. The challenge is heightened for many sectors that experience a slow period in January and February, while provisional tax and GST payments are due on 15 January for businesses with a 31 March balance date.
This year brings additional pressure with the 2025/2026 Christmas and New Year public holidays falling midweek on Wednesdays and Thursdays. This creates a fragmented two-week period where many businesses will close or operate at reduced capacity.
Let’s look at why Christmas creates cashflow challenges and what options can help you navigate this seasonal period more smoothly.
Why Christmas creates cashflow challenges for NZ businesses
The period after Christmas is traditionally slow. For sectors like hospitality or retail, there’s a surge in demand before Christmas that makes the January drop-off particularly harsh.
Additional pressures businesses can come under include:
- business closures or reduced capacity over the break – less income generated
- employee incentive schemes and bonuses paid before Christmas – draining cash reserves right before the quiet period
- reduced consumer spending in January and February – as consumers apply more caution after the holiday spending surge
- inventory tied up in stock – particularly challenging for retail businesses with cash locked in unsold summer ranges
- slower bank processing times – public holidays and weekends can delay payments arriving in your account
Together, these create what many business owners know as the “summer squeeze” on cashflow, with added pressure to cash reserves with the 15 January provisional tax deadline.
The 15 January provisional tax deadline
With these seasonal challenges, it’s no surprise many businesses struggle to manage cashflow and meet the 15 January provisional tax deadline.
Unfortunately, Inland Revenue doesn’t factor in these seasonal challenges. They’ll charge 3.27% late payment penalties and 9.89% use of money interest (UOMI) if tax isn’t received on the due date (rates as at May 2025).
Many businesses find this timing particularly challenging given the seasonal slowdown and reduced cash reserves after the holiday period.
Ways to manage your Christmas cashflow
So what are your best options?
Many businesses take a proactive approach to their Christmas cashflow. Here are a few key areas to consider:
Accounts receivable – review outstanding invoices before the holiday period and follow up with customers to improve collection timing. Early December works well to encourage payment before businesses close for the break.
Supplier relationships – if you have good trading relationships and have been a reliable payer, consider discussing your payment schedules with suppliers over the seasonal period.
Planning ahead – create a cashflow forecast covering the December to February period. This helps identify potential gaps in advance, including reduced trading days, holiday bonuses, and the 15 January tax payment.
Every business situation is different. It’s worth discussing your specific circumstances with your accountant or financial adviser.
A smarter way to manage tax payments
Looking at your provisional tax payment timing? TMNZ offers a smarter alternative.
Tax pooling through TMNZ is approved by Inland Revenue and trusted by New Zealand businesses. It lets you defer provisional tax payments to a time that suits you, without incurring late payment penalties and UOMI.
It’s more affordable than many traditional forms of finance, doesn’t affect your existing credit facilities, and requires no credit checks or security.
You only pay back what you actually owe. If your tax liability is less than expected, you don’t need to repay the full amount. And the finance arrangement can be easily extended.
How it works
Say you need to defer a $5,000 provisional tax payment for 6 months. You’d pay TMNZ a one-off, tax-deductible interest amount, and we’d arrange the $5,000 provisional tax payment on your behalf.
The interest amount is based on the tax amount financed and the deferral period. In this instance, it would be roughly $130.
The provisional tax payment is held in an IRD account administered by Guardian Trust. They instruct IRD to transfer the tax into your IRD account when you repay the $5,000 principal in 6 months.
IRD treats the $5,000 provisional tax as paid on time once the transfer is processed. It’s that simple.
Key benefits of tax pooling:
- IRD-approved
- doesn’t impact your existing credit facilities
- no security or credit checks required
- flexibility to adjust if you owe less tax than expected
Planning ahead for the summer period
The businesses that navigate Christmas cashflow most successfully? They start planning early. Consider reviewing your cashflow position in October or November, before the holiday rush begins. This gives you time to understand your position and explore options that work for you.
Your accountant can help you assess your specific situation and what approaches might work for you, including whether tax pooling could be the right solution for managing your 15 January provisional tax obligations.
Take control of your summer cashflow
Christmas doesn’t have to be stressful for your cashflow. With forward planning and the right solutions, you can navigate the seasonal challenges while keeping your business on track.

Why smart CFOs are turning tax into competitive advantage: 10 game-changing benefits for larger businesses
With the 28 November provisional tax deadline approaching, corporate businesses with June balance dates have a choice to make. Pay Inland Revenue directly and lock your funds away. Or turn that tax obligation into a strategic financial tool.
Over 25,000 businesses have chosen the smarter path with TMNZ, saving more than $520 million through our flexible tax payment solutions.
Tax pooling with TMNZ isn’t just about avoiding penalties anymore. It’s a strategic tax management approach that turns a fixed obligation into a flexible financial instrument that gives your company a real competitive advantage.
The Strategic Shift: From Tax Burden to Financial Asset
As the originators of tax pooling, approved by Inland Revenue since 2003, we’ve watched it evolve from a compliance tool to a sophisticated financial strategy suitable for any large business with complex tax obligations.
Here’s how smart CFOs are using TMNZ’s tax pooling solutions to outmanoeuvre their competition:
1. Save significant costs
Large businesses often carry substantial tax liabilities. With TMNZ, these obligations become opportunities for considerable savings on Inland Revenue interest and penalties.
But here’s where it gets interesting: your company can earn more on overpaid tax.
While your competitors tie up funds with IR, earning minimal credit interest, you’re generating higher returns that flow directly to your bottom line.
The numbers speak for themselves; some of our larger clients save hundreds of thousands of dollars annually. That’s real money that can fund growth initiatives, acquisitions, or shareholder returns.
2. Retain working capital
TMNZ lets you retain large sums of working capital for longer periods. Instead of sending substantial payments to Inland Revenue months before they’re actually due, you keep that capital actively working in your business.
You can use that money to fund high-return investments and acquisitions, or maintain liquidity to capitalise on market opportunities.
Your working capital becomes strategic ammunition, rather than locked-away tax payments.
3. Manage risks
Large businesses can face complex tax risks that can challenge even the most prepared finance teams. Unexpected liabilities, reassessments, and penalties can hit at the worst possible times.
TMNZ can help as a valuable part of your company’s corporate tax management strategy. Get protection against financial curveballs and the flexibility to respond quickly when circumstances change.
4. Simplify compliance
Managing compliance across complex tax structures can feel like juggling flaming torches. TMNZ helps alleviate wasted time by simplifying tax management processes across your company.
No more scrambling to meet multiple tax deadlines or managing cash across various entities. One strategic tax management approach that covers all your bases.
5. Improve financial reporting
TMNZ provides more predictable tax expenses, which enhance key financial ratios that matter to stakeholders, lenders, and potential acquirers.
When your business tax management strategy contributes to stronger financial metrics, you’re building value that extends far beyond simple compliance.
6. Protect against market volatility
For businesses heavily impacted by fluctuating markets, TMNZ offers protection against interest rate volatility by allowing you to lock in rates in advance, removing another variable from your financial planning equation.
This is especially valuable during periods of economic uncertainty when interest rate changes can significantly impact your cost structure.
7. Structure flexible payments
Standard Inland Revenue payment dates weren’t designed with your specific business rhythm in mind. TMNZ lets you structure tax payments around your unique cashflow patterns rather than arbitrary government deadlines.
This flexibility gives you real control over your funds. Earn higher interest on overpayments, access funds as a fee-free line of credit or carry them forward to future years. Our strategic tax management services work for your business, not against it.
8. Turn overpayments into assets
Paid too much? Don’t wait months for IRD to process refunds. Access overpaid amounts within 3-5 days without filing returns. Or earn above IR’s credit rate by on-selling surplus tax. Some corporates earn 2-3% above IR rates on excess deposits.
9. Provide scalable growth
As your business grows and evolves, your tax payment solutions scale with you. Whether you’re expanding into new markets, acquiring competitors, or adapting to changing tax landscapes, your tax strategy remains flexible and responsive.
This scalability means you’re not constantly rebuilding your tax approach as your business situation changes. Your foundation remains strong while adapting to new circumstances.
10. Gain expert support
Our expert team of Chartered Accountants, tax lawyers, and customer success specialists provide personal support when you need it most. They understand the complexities of larger business tax situations, and when hundreds of thousands of dollars are at stake, having direct access to expertise that matches the sophistication of your tax challenges makes all the difference.
The 28 November opportunity
Acting before 28 November gives you maximum flexibility and tax efficiency. Here are a few scenarios and outcomes we commonly see in our corporate clients:
- Scenario A: You’re confident about profitability – Deposit your tax payment into TMNZ’s pool to earn higher interest than IRD pays, maintain complete flexibility, and access funds within days if needed.
- Scenario B: Cashflow is tight or better deployed elsewhere – Use Tax Finance to defer payment. Our current rates are significantly cheaper than standard bank overdraft rates. No security required. Approval guaranteed.
- Scenario C: Uncertain about your final position? Swap tax across dates to minimise exposure. Buy tax retroactively if you’ve underpaid. Sell surplus if you’ve overpaid.
Turn tax obligation into tax efficiency
Whatever your current tax position, TMNZ offers more control and better financial outcomes than paying IRD directly. Whether you want to earn more interest on overpayments, need payment flexibility, or want to avoid expensive banking services, the opportunity is clear.
The 28 November deadline is approaching fast. Smart CFOs are already positioning their businesses to turn tax season into competitive advantage season.

TMNZ & CA ANZ IRD Satisfaction Survey 2023
TMNZ and CA ANZ have worked together to bring you the results of the 2023 Satisfaction Survey.

The annual survey is conducted jointly by CA ANZ and Tax Management New Zealand (TMNZ) to provide insight into what tax practitioners think of the way in which IRD administers the tax system.

How tax pooling can help your tax management
Meet Andy, a builder who has run his own business for three years. Things are going well, and he’s set to make a substantial profit in the current financial year. He’s well-paid and smart enough to set aside tax he owes with each payment. But clients don’t always pay him on time, causing some serious headaches.
Like many businesses, Andy experiences cashflow issues. He makes a profit but doesn’t always have enough funds in his account to pay provisional tax when it’s due.
What should Andy do? Grin and bear the Inland Revenue’s late payment penalties and use of money interest charges after missing his payment dates? Or seek a better option?
Luckily, Andy’s accountant Lisa knows all about tax pooling and how it can relieve the financial pressure.
Tax pooling explained
Andy asks his accountant how tax pooling works and some of its main benefits.
Lisa explains that tax pooling has been available to taxpayers for two decades, starting in 2003 when TMNZ became a registered provider with IR.
The accountant says tax pooling has clear benefits over traditional tax management:
- Taxpayers can choose to pay their liabilities in a time and manner that suits them, without having to worry about IR interest and penalties.
- They can make significant savings on use of money interest charged and eliminate late payment penalties if they miss or underpay provisional tax, or if they are reassessed by IR.
- When taxpayers overpay into the TMNZ tax pool, they can earn a much higher rate of interest on overpayment of funds than they would receive from the IR.
Who oversees TMNZ’s tax pool?
Lisa assures Andy that all payments made into TMNZ’s tax pool account at the IR are managed by an independent trustee, Guardian Trust.
Guardian Trust oversees the bank accounts into which taxpayers pay their money, as well as the transfer of funds from the TMNZ tax pool to Andy’s IR account.
Because the tax being transferred has been paid and date stamped as at the original due date, any penalties and interest are wiped once the payment is processed by the IR.
Companies of all sizes can use tax pooling
Tax pooling can help businesses of all sizes, from companies with thousands of employees down to sole traders. TMNZ’s tax pool is the largest and most established in the country.
Lisa’s research found two companies TMNZ has helped.
One company uses tax pooling to counteract fluctuating seasonal revenue:
“It takes away all those stresses. You’re passing it on to somebody else and saying, ‘take care of this for me, I don’t know what to do, we’ve got a shortage of cashflow’ and it’s the best way of putting more energy into your business and doing the things that you’re good at.”
The second company uses a tax pool as they need to invest in equipment regularly.
"With a business like ours, we are investing quite heavily into assets like cars, campers, and boats. Cash upfront is important [for] us to have.”
TMNZ has helped both companies manage working capital and mitigate the risk of fees and penalties.
“What is the cost of this?” Andy asks.
“Just TMNZ interest,” Lisa replies.
Tax pools can help with voluntary disclosures and audits
Lisa looks through Andy’s expected outgoings for the year. These range from the cost of living to many other expenses associated with owning a business.
The accountant realises that in a previous year, Andy made a mistake on one of his returns and must file a voluntary disclosure with the IR.
“How can Andy get ahead with the current year if he now has to pay an additional amount of tax for a past year?” Lisa wonders.
TMNZ can assist taxpayers who owe an increased amount of tax as a result of a voluntary disclosure or audit.
Tax pooling provides 60 days from the date the IR reassessment notice was issued to buy the tax payment he needs and send it to the IR.
The different tax types available to purchase are historic income tax payments, deferrable tax, and agreed delay tax, as well as other tax types such as GST, RWT, PIE, FBT, NRT, and DWT.
Lisa can use TMNZ to reduce the interest and late payment penalties cost of Andy’s voluntary disclosure.
For the current tax year, Lisa can set up either a Flexitax or Tax Finance arrangement to give him more flexibility and time to pay (up to 75 days past his terminal tax date for that tax year).
Lisa has other clients that are medium-large taxpayers with big bills and paydays. TMNZ’s Tax Deposit solution can help them.
Other advantages of tax pooling
There are several other advantages to using a tax pool:
- Excess funds paid into the pool can either be used for future dates and any other tax types where a reassessment has not been issued.
- There’s the option to sell surplus tax to a taxpayer who has underpaid to earn additional interest.
- The refund process is much faster than directly through the IR (within three to five days, and without having to file a return for the year).

Harrison Grierson mitigates provisional tax risk
For Matthew Fleming, provisional tax is risky business as it requires a degree of crystal-ball gazing and guesswork.
However, he chooses to mitigate that risk by depositing these payments into TMNZ's tax pool.
It's a “no-brainer” because it gives him a better return if he overpays provisional tax and reduces his interest and late payment penalty costs if he underpays.
More about Matthew Fleming
Matthew is the chief financial officer at Harrison Grierson, one of New Zealand’s leading engineering and design consultancies.
It has offices throughout Aotearoa and predominately provides services locally, with more than 350 staff on the books.
Remarkably, the firm is blowing out 135 candles this year. No one stands the test of time for that long if they ain’t good at what they do.
And Harrison Grierson is good at what it does. A quick peruse of the significant projects it has been associated with during its lifetime is a testament to that.
Provisional tax is 'difficult to predict'
However, like most businesses, it is not immune to the problems provisional tax poses.
Matthew admits calculating the amount of income tax Harrison Grierson must pay Inland Revenue (IR) requires guesswork as its cashflow is up and down at certain times.
He knows the lay of the land during the first quarter – but the rest of the year can go either way.
Matthew says:
“It’s hard enough to try and guess next month’s results, but when you’re having to guesstimate your final year’s tax liability accurately, [it] does take a certain degree of crystal-ball gazing. We try to project our income and where our costs are going to be and having to pay tax on that sort of basis is a little bit of a risk.”
Even more so when one considers the taxman’s wide interest spread. As at the time of writing, they charge 8.35 percent if someone underpays provisional tax and pay just 0.81 percent if they overpay.
In other words, provisional tax is difficult to get right and very expensive when someone gets it wrong.
How Matthew manages that risk
Matthew chooses to deposit Harrison Grierson's provisional tax payments into TMNZ's tax pool.
It's an account operated by an IR-approved tax pooling provider that allows taxpayers to combine their payments. The overpayments from some can then be used to offset the underpayments by others.
TMNZ's tax pool account sits at IR and is overseen by an independent trustee.
Harrison Grierson keeps its date-stamped tax deposits in this account until Matthew confirms its liability for the year. He then arranges for the transfer of these deposits to the firm's own IR account to satisfy what they owe.
If they have surplus tax remaining, he can earn additional interest by selling this to someone who has underpaid (subject to market demand).
Conversely, if not enough tax has been paid, Matthew can reduce the IR interest cost and eliminate any late payment penalties Harrison Grierson faces through purchasing the tax they require from another taxpayer and applying it against the company’s own liability when he arranges their transfers from the pool.
Matthew: 'TMNZ makes provisional tax easier'
Matthew is a big proponent of the benefit TMNZ delivers when his provisional tax calculations go askew.
He says:
“[Tax pooling’s] such a great service in terms of advantaging taxpayers when they are trying to estimate their liabilities and are struggling with it. The ability to get a return when you have overpaid and the ability not to pay such punitive penalty rates when you have underpaid makes it a no-brainer.”
As someone who is having to estimate revenue and costs a lot, Matthew finds it useful that tax pooling gives him the flexibility and control to make payments “as we see fit” based on how the financial year is unfolding, without any considerable downside.
He also likes that he can access refunds faster – and without having to file a return. TMNZ makes it simple for him to manage the payments of the different entities belonging to Harrison Grierson as well.
Matthew recommends tax pooling to other businesses, particularly those with seasonal or volatile income.
“What makes TMNZ an easy choice is it makes the whole provisional tax regime easier to deal with.”

Jucy Rentals Group say good bye to provisional tax stress
They say you can't make an omelet without breaking some eggs. In this context, a company cannot grow without taking some risks or investing in their business.
Jucy Rentals Group's day-to-day operations highly depend on cash in the bank. It faces a unique challenge when it comes to paying provisional tax. They have to account for two things:
- The seasonality of business with summertime as their peak period
- Investing into their products regularly.
The company's CFO, Jonathan Duncan, found a way to manage cashflow by using TMNZ tax pooling solutions Tax Deposit, Tax Finance and Flexitax to create structure around outgoing payments during the year.
The strategy is simple: Pay into the TMNZ tax pool using Tax Deposit when the cash is available; then if any top ups are required, pay through the tax pool with Flexitax or Tax Finance.
"It gives us the ability to manage our cash flows around that as to what works for us rather than trying to fit in with the timeframes of Inland Revenue and that is a big benefit for us," explains Jonathan.
Jucy Group have settled into the benefits of tax pooling through TMNZ.
How to find a great accountant: six qualities to look for
Thousands of independent business owners have an awful habit.
While steadily pedaling up the mountain of expansion, new hires, building a great brand, and newfound social media fame, these business owners attempt to juggle their tax payments and financial accounts with their little remaining time.
“We know our business best, so we’d may as well sort out the taxes ourselves…”
Maybe you are one of these owners.
Perhaps you’re putting off hiring an accountant due to the perceived expense.
Don’t delay! Your business can run more smoothly and efficiently than ever with an accountant’s help. An accountant with the right expertise will help you meet tax obligations and provide peace of mind at every stage of your business growth.
It’s time to leave the financial headaches to the professionals. We’ve compiled a list of reasons to convince you – as well as six qualities to identify in a great accountant – so you can keep the focus on nurturing and growing your business.
Should I hire an accountant?
The short answer is – YES.
A great accountant will help with:
- Forecasting
- Tax reporting
- Managing cashflow
- Paying provisional tax and assisting with Inland Revenue (IR) compliance
Unless you’re familiar with tax structures, hiring a chartered accountant is crucial to the success and longevity of your business, and is money well spent.
How do I choose the right accountant?
From start-ups to industry giants, all businesses benefit from hiring an accountant who can assist with managing risk and planning for growth. Provisional tax can be a contentious issue for small business owners.
Your accountant can ease the impact of provisional and terminal tax dates on your business by using tax pooling. Tax pooling gives you control over your provisional payments so that you aren’t stung with use of money interest and penalties if you miss or underpay IR.

We recommend you treat your search for an accountant as seriously as you would the recruitment of a new employee. You might seek word-of-mouth referral from peers, friends and family members. Ask them for feedback on your short-listed accountants, you may learn something your research wouldn’t have included.
Look for accounting firms with a similar size to your own company. As a rule, small to medium firms provide a more personalised service specialising in small business work and often have more competitive rates compared to larger accounting firms.
What questions should I ask an accountant?
In your search to find an accountant, look for these qualities:
- Are they registered as a chartered accountant in NZ? These professionals are experts in their field and adhere to the strictest NZICA Code of Ethics.
- How are their communication skills? Jargon is useless to you. Your accountant should be able to explain budgets and financial reporting in layman's terms for you and your team to easily understand.
- How much experience do they have with your business type or industry?
- What are their costs? Will they bill you hourly or monthly? Do they have a fixed fee?
- Do they have an entrepreneurial mindset, think outside the box and embrace innovation?
- Are they flexible and open to change? Your business will continue to grow and evolve. Your accountant needs to help you adapt to this change and manage it financially.
Once you find an accountant in New Zealand who you believe can help your business develop and grow, take the time to establish and nurture a solid, long-lasting business relationship.
Finding the best accountant for your business
Taxes, end-of-year-reports and ever-changing laws and legislation can get complicated. Don’t leave yourself open to penalties and interest. Find an accountant who understands your business and is willing to work with you to meet your goals.
The six qualities listed are a guide to help you find the best fit for your business. A good accountant may be an investment at first, but it is one you will be very grateful for in the long term. Take your time looking for someone who is qualified but also someone you get along well with as the relationship is just as important along the way to success.
Five essential accounting tips for small and medium businesses
Getting the right small business accounting advice is vital for the success and growth of your small business. Here are five essential tips to help organise accounting for your small business.
Keep a record of tax deadlines
Knowing when business taxes are due throughout the financial year is crucial for the health of your small business. If you miss an important deadline, you could receive a costly penalty.
In New Zealand, staying on top of GST returns and paying provisional tax on time is especially important.
Inland Revenue (IR) has resources available to remind you of these important dates. You can also check out our provisional tax calendar to see your terminal tax and provisional tax dates. It is important to be proactive about tracking these yearly deadlines to meet your ongoing tax obligations.
Make the most of automated accounting software
Automated accounting software can be a lifesaver for small businesses. Accounting software covers many of the fundamentals of running a small business. This software helps keep track of expenses and automatically generates forms and reports about your business. This lightens the load of your day-to-day accounting practices.
TMNZ is integrated with accounting software such as Tax Lab to make it that much easier and convenient to use tax pooling if a payment has been missed. To get the most out of accounting software, we would recommend a chartered accountant look over the specifics of your business for any gaps that may have inadvertently been overlooked.
Know your limits and hire a professional when necessary
Many small to medium business owners try to tackle bookkeeping on their own to save costs. But in the end, making errors or filing expenses incorrectly could prove costlier than hiring a professional.
Maintain a relationship with a chartered accountant who can help keep your books tidy. A reliable accountant can help you arrange tax pooling for your business. Tax pooling provides you with more control and flexibility to manage tax payments and can save your business money from late payment penalties and use of money interest.
You may only need your accountant’s services several times a year. However, having a professional on hand for accounting advice gives you precious peace of mind that your accounting is in order.
Don’t get caught out by unexpected costs
The longer your business is in operation, the more likely you are to face a large, unexpected cost. For example, you may find yourself needing to repair or upgrade your business’ equipment. This is costly, but unavoidable for your business to operate.
An unexpected cost could even come in the form of an opportunity to grow your business, such as a market gap that you could fill perfectly. Taking advantage of such opportunities requires up-front investment.
In either case, expect the unexpected and put money aside to cover unforeseen operational costs. Or consider using your tax payments as a line of credit with Tax Drawdown.
This is sound advice for any small business. Doing so will save you the headache of scrambling to cover a significant bill or missing out on the chance to grow your business.
TMNZ is trusted by thousands of Kiwi small and medium-sized businesses. We are the leading tax pooling provider in New Zealand and work closely with IR to ensure our services are secure and reliable.
