How we performed

Processing performance measures focus on timeliness and efficiency for the key services and activities that affect customers. Our systems and more automated processes have made IR more efficient in the processing of customers’ returns, registrations, payments and refunds.

In 2024–25, we:

  • processed 12.6 million returns (income tax, GST and employer information)
  • issued 1.3 million refunds (income tax and GST)
  • transferred $10.7 billion to KiwiSaver scheme providers
  • processed 691,000 registrations.

Performance measure results

This year, we achieved 7 out of 8 targets, the same as in 2023–24.
