This year, IR has increased the focus on ensuring high levels of compliance from customers with their tax obligations to maximise revenue and minimise debt.
At the core of our operations has been our compliance approach: the work we’ve done to make it easy for customers to get tax and entitlements right, hard to get it wrong and costly for those who try to avoid their obligations.
In this section
Read about the range of approaches we used to administer tax and payments and to be more effective and efficient in doing it.
You can read more about other aspects of our operations elsewhere in this report:
- The section on Progressing our Strategic Intentions has a medium to longer-term view of how we’re performing and where we’re headed.
- The previous section on Implementing the Government’s Priorities covers the policy and Budget initiatives we progressed.
We met 26 out of our 31 service performance measure targets. You can read more about these in the next section.
