Tax reform insights from a global policy expert

Tax reform insights from a global policy expert

Author: CPA Australia May 5, 2026 Duration: 20:00

Tax reform. 

It's one of the most hotly debated issues around the world

And as global tax expert Viva Hammer notes, the biggest barrier to tax reform in Australia is not policy  it is the pursuit of perfection. 

In this episode of With Interest, she brings a global perspective shaped by her work on significant tax reforms in recent US history. 

Her message is clear: progress comes from doing something better, not waiting for something perfect. 

Main learnings include: 

  • lessons from US tax reform and what Australia can apply 

  • why "better, not perfect" is critical for improving tax reform 

  • how predictability drives investment more than headline tax rates 

  • how to provide certainty for international investors 

  • the role of GST as a more efficient and sustainable tax base 

  • the fairness of corporate tax versus consumption and land taxes 

  • where Australia sits in the global tax competition landscape 

As we head toward the 2026 Federal Budget, it's clear that governments, businesses, and the accounting profession are grappling with complex and interconnected challenges  from investment certainty to intergenerational fairness and the future of our tax mix. 

This episode is a timely look at a key issue with one of the most respected global voices in tax. 

Tune in now.
