Australian business register application programming interfaces

This page provides links and information for software developers (SwDs) in regard to the development of Application Programming Interfaces (APIs) for Australian Business Register (ABR) and Australian Taxation Office (ATO).


Measures for Streamlining business registrations were announced in the 2015 Budget - Growing jobs and small business. These aim to reduce red tape for business owners, making it quicker and cheaper for them to transact online with government so they can concentrate on growing their businesses. The Government is progressing this in three parts:

  1. A simple to use single online business registration space on
  2. A single business identifier
  3. Releasing the Application Programming Interface (API) code for online registrations.

The ATO and ABR are developing APIs to enable third party software vendors to consume and provide a retail offering of ABN and tax role registrations.

This will enable vendors to deliver applications for these registrations within their products giving broader accessibility for business intenders to register through external providers.

This work is scheduled to be completed in early 2017.

The Minister for Revenue and Financial Services commissioned an implementation study to assess the economy-wide impacts of adopting a single business identifier (SBI). This study has shown that the SBI measure would have large transition costs to upgrade existing IT systems and processes that rely on the three generic business identifiers (ABN, ACN and Business TFN).

The study concluded the government could pursue its objectives through its digital transformation. The government will not abolish company numbers and instead progress measures to improve the way it connects with business through digital transformation.
