About TMNZ

TMNZ is New Zealand’s leading tax payment intermediary. Our clients include thousands of small and medium-sized businesses as well as some of New Zealand’s largest banks, state-owned enterprises and well-known corporate names. TMNZ sets the very highest security standards for reliable and secure management of our clients’ tax payments.

No-one understands tax pooling better than TMNZ. Our founder Ian Kuperus helped to pioneer the industry back in 2001. Since then, he was made a fellow of Chartered Accountants Australia and New Zealand to recognise his contribution.

About Tax Pooling

Tax pooling is an IRD approved service that helps businesses make the right tax payments at the right time.

So instead of paying IRD directly, taxpayers pay into the tax pool when it suits them and TMNZ makes payments to IRD on their behalf. It’s like a balancing act; since some businesses like to overpay tax during earlier dates, this helps to cover those businesses that need more flexible tax payment arrangements. And that’s the tax pool.
