About Smart Donation

Smart Donation is a service provided by Tax Management NZ (TMNZ).

They want to offer a safe, IRD-approved service that gives taxpayers greater flexibility and control around how and when they make provisional tax payments. Who is TMNZ?

  • Pioneers of tax pooling and New Zealand’s largest tax pooling provider.
  • Helped more than 26,000 businesses save over $160 million in IRD compliance costs.
  • Consistent record of innovation and service with unmatched tax pooling knowledge and experience.
  • The only tax pooling intermediary to be led by former corporate tax managers.


TMNZ founder Ian Kuperus helped to pioneer the tax pooling industry and in 2014 he was made a fellow of Chartered Accountants Australia and New Zealand specifically to recognise his contribution to the tax industry.

Today their clients include the majority of New Zealand’s largest taxpaying banks, state-owned enterprises and well-known corporate names, as well as thousands of small and medium-sized businesses.

With the largest and most established tax pool in New Zealand, TMNZ sets the very highest security standards for reliable and secure management of our clients’ tax payments.

All tax payments and deposits to TMNZ go into trust accounts administered by Guardian Trust, New Zealand’s largest corporate trustee. Guardian Trust also oversees the TMNZ tax pool account at IRD.

They offer an innovative platform so clients can manage their provisional tax online, supported by a dedicated client team providing expert advice.
