How we can help you

With our tax pooling products and services, you can make your tax payments match your cashflow and pay as you go or defer your tax payments and keep the money in your business longer. Our solutions offer up to 30% savings on interest and can eliminate late payment penalties charged by Inland Revenue. Acceptance is guaranteed, and no security is required.

Pay as you go with Flexitax

Pay your provisional tax in lump sums or spread out tax payments over time (up to 75 days after your terminal tax date). The interest charged is tax-deductible and based on competitive lending rates.

Defer your payment with Finance

Make your provisional tax payment in full on a date you choose. We then transfer back-dated tax into your Inland Revenue account, so it’s as if you paid on time. The fee is tax-deductible and based on competitive lending rates.

We’re proud to invest all our profits in local communities and the environment, through our philanthropic partner, the Whakatupu Aotearoa Foundation.

Hear from our clients

Harrison Grierson

Provisional tax is risky business as it requires a degree of crystal-ball gazing and guesswork. Matthew Fleming, CFO at Harrison Grierson chooses to mitigate that risk by depositing these payments into TMNZ’s tax pool account.

“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.”
