Voluntary Tax Transparency Code

A set of principles and minimum standards to guide medium and large businesses on public disclosure of tax information.

Last updated 16 November 2021

The Tax Transparency Code (TTC) is a set of principles and minimum standards developed by the Board of Taxation to guide medium and large businesses on public disclosure of tax information.

Adoption of the TTC is voluntary and intended to complement Australia’s existing tax transparency measures. The TTC is designed to encourage greater transparency by the corporate sector, and to enhance the community’s understanding of the corporate sector's compliance with Australia’s tax laws.

Published TTC reports can be accessed at data.gov.auExternal Link The list of TTC reports is updated monthly.

Role of the ATO

We facilitate the TTC by hosting a centralised database of links to published TTC reports provided to us by participating businesses. The links to published reports and details on signatories are available at data.gov.auExternal Link

We don't review or provide any assurance on the accuracy of the information contained in these reports.

Voluntary TTC disclosures by businesses don't change our legislative duty to produce the annual Report of entity tax information.

For businesses wishing to provide us with their published TTC report, refer to the instructions below.

Who should disclose?

Medium or large corporations, including super funds, trusts and partnerships are encouraged to adopt the TTC. Corporations need to register with the Board of Taxation to become a signatory to the TTC.

To become a signatory to the Register, email taxboard@treasury.gov.au.

For the purpose of the TTC:

  • medium businesses are businesses with aggregated TTC Australian turnover of at least $100 million but less than $500 million
  • large businesses are businesses with aggregated TTC Australian turnover of $500 million or more.

Note: 'TTC Australian turnover' is defined in section 5.1 of A Tax Transparency Code (PDF, 996KB)This link will download a file – the Board of Taxation's final report to the Treasurer (February 2016).

Information to disclose

The minimum standard of information required under the TTC depends on the size of the business. Information disclosed under the TTC is divided between Part A and Part B content. It is recommended that:

  • medium businesses adopt Part A
  • large businesses adopt both Part A and Part B.
