International tax governance is significant societally as it impacts both inequality and the capacity of governments to deliver on their social contracts. Tax experts forma key, under-researched, heterogeneous element of the tax ecosystem, subject to a range of hard and soft governance influences.

Soft governance, including that of the workplace and the profession, is most influential in challenging regimes. Beyond a tipping point of economic freedom, regulatory knowledge and the threat of sanction become less influential.
