The Minister of Revenue introduced the Taxation (Annual Rates for 2025–26, Compliance Simplification, and Remedial Measures) Bill in August 2025. It includes proposed changes that, if passed, will take effect on or before 1 April 2026.

Our upcoming webinars cover those changes as well as:

  • updates from Budget 2025 coming into effect
  • residual items from the previous Taxation Act
  • regular rate and threshold adjustments
  • other enhancements.

Webinars on changes coming to employers and GST have already been published.
These can be found in the pages below, in this section.
