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.

Tax Finance: An alternative funding source
Growing a business is hard yakka. More specifically, it costs money.
And therein lies a problem for many small business owners: Cashflow. In fact, it’s not a problem. It’s a major problem. According to Xero’s Small Business Insights, New Zealand business sales fell by over 8% for the year ending June 2024.
Now granted, there are several choices available when it comes to accessing funds you need to. A bank loan, overdraft, credit card and an unsecured loan are just some.
But again, it’s not that simple. There can be a few hoops to jump through as part of the approval process and you will likely have to use assets as collateral, often using your personal house (or the house of a shareholder, for example) as security to get a lower cost of funds. If there is no approval or credit review process, then chances are you will be up for double-digit interest rates. Ouch.
However, there is another option. It’s one you probably have not heard about either.
The other option – Tax Finance
Did you know that your provisional tax payments are also a source of finance? Yes, that’s right – provisional tax. That thing many small business owners loathe paying. That thing that places undue pressure on, you guessed it, cashflow.
Allow us to explain.
An IR-approved tax pooling provider such as TMNZ offers a payment option known as Tax Finance. It lets you free up working capital by deferring a provisional tax payment to a later date, without incurring Inland Revenue (IR) interest of 9.89% (as at 8 May 2025) and late payment penalties.
For an upfront finance fee, you can choose a time in the future you wish to pay what you owe. Essentially, this allows you to use the money you have set aside for income tax more productively.
The finance fee or interest you pay to TMNZ is:
- similar to the interest rate charged by a bank for a residential mortgage; and
- tax-deductible.
So, you could also use the money set aside to repay your mortgage earlier, thereby reducing non-deductible interest costs charged by the banks on your personal house. The cost of Tax Finance is cheaper than using your business overdraft or an unsecured loan. Approval is guaranteed. Moreover, you do not have to provide any security.
Even better, if you already have paid tax deposits into the TMNZ tax pool, you can finance them back out while keeping the original tax date. We call this Tax Drawdown.
Altogether, this effectively treats your tax payments with the TMNZ tax pool as a revolving credit facility.
Who might Tax Finance suit?
Tax Finance will suit those who:
- are looking for funding that does not affect other lines of credit or their General Security Agreement with their bank
- want to keep headroom in their existing lending facilities
- do not wish to go through the rigmarole of the normal lending process
- want a fixed interest cost
- feel there is more to gain financially from being able to keep money in their business instead of paying income tax.
How much does Tax Finance cost?
It depends. The finance fee is based on the amount of tax due and the future date you wish to pay.
As mentioned above, the TMNZ finance fees are similar to the home loan mortgage interest rates charged by banks.
For instance, at current rates¹ it only costs $335 to defer a $10,000 provisional tax payment for six months. That works out to be approximately 6.70%pa².
How does Tax Finance work?
Here’s how Tax Finance works in a nutshell:
- Ahead of your provisional tax payment date, you tell TMNZ the amount of tax you want to finance, the future date you want to finance that to (e.g., the date you think you may be able to pay the tax amount) and pay the finance fee based on the quote TMNZ provides. TMNZ arranges for a bank to make a payment for you in its tax pool account at IR on the provisional tax date. This payment is date-stamped.
- At the agreed upon future date (known as the maturity date), you have a few options:
- settle the full tax amount by paying TMNZ; or
- roll over the financed amount for another period of time – in this case you can get a quote for a further finance fee to pay based on how long you want to finance for;
- settle part of the financed tax and roll over the remaining part;
- settle only the amount you need (if your actual tax liability has reduced).
- Upon settlement of the financed tax, ownership of the tax deposit made by the bank changes to become owned by you and sits in your tax pooling account with TMNZ. You can then request TMNZ to transfer the tax payment it is holding on your behalf to your IR account to clear your tax liability. Once they’ve processed the transfer, IR treats this tax amount as if the tax was paid on your original provisional tax date. It will also reverse any interest and late payment penalties showing on your account.
In the event you choose the fourth bullet in step 2 above, there is no obligation on you for the remaining financed tax (even if you decide to not settle any of the financed tax). You can simply walk away, no questions asked. Or you can ask us to try and sell the residual unused financed amount for you and earn you some interest return, effectively getting some of your finance fee back.
TMNZ offers a competitive rate for Tax Finance. For more information, get in touch.

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).

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.
