About the Large Business Stewardship Group

The Large Business Stewardship Group is one of the stewardship groups operated by the Australian Taxation Office (ATO) to help improve the client experience and administration of Australia’s tax, super and registry systems.

The group provides an opportunity for strategic discussion to improve the administration and operation of the tax, super and registry systems into the future.

The group is focussed on:

identifying opportunities to improve the tax and super systems to make it easy to get things right and hard not to, through an understanding of the effects on the large business sector
gaining insights into issues faced by the large business sector to improve future approaches and processes
providing opportunities to discuss the strategic direction of the tax system, specifically, opportunities for improvements to its administration and supporting key relationships that reflect the broader community
providing an effective and dynamic approach to community consultation and engagement in relation to the design and administration of the tax system by the ATO.
