Our vision

To achieve an internationally competitive and robust corporate tax system under which large corporates willingly meet their tax obligations in a timely and transparent manner

Our objectives

  • To increase community and Government awareness around the effectiveness and integrity of the Australian corporate tax system and the significant and ongoing contribution large business makes to Australia
  • To influence and develop tax policy that contributes to a corporate tax system under which large corporates cooperatively meet their tax obligations within a globally competitive tax system
  • To improve the administration of the corporate tax system and reduce the cost of compliance
  • To facilitate the implementation of best practice among our members by promoting corporate transparency and assisting and supporting them in their interactions with the Australian Taxation Office, the Treasury and Government
  • To provide ongoing peer support and thought leadership through an ongoing program of initiatives aimed at supporting our members’ professional development

How we seek to achieve our objectives

  • By working constructively and maintaining regular contact with the Government and Opposition, the Treasury and the Australian Taxation Office
  • Through the publication and distribution to members of materials relevant to managing a tax function in a large corporation
  • Through the publication of documents to the wider community on the operation of the corporate tax system and the contribution large corporate taxpayers make to the Australian economy
  • By maintaining regular and personal contact between members and the Secretariat
  • By leading discussion group meetings and working groups between members on general tax issues and specific issues
  • Through liaising with other industry associations, the Board of Taxation and other regulatory bodies such as the Inspector General of Taxation
