It is a legal necessity to tell the Registrar of the Australian Business Register within 28 days of any changes in your registered business details, including:
- postal, email or business address
- main business activity
- Australian Company Number (ACN) or Australian Registered Body Number (ARBN)
- public officer (must be in writing)
- name of trustees.
You should also tell the ATO about any changes to your:
- entity name or registered business name (registered with the Australian Securities and Investments Commission)
- official contact person
- financial institution account details.
It is your duty to maintain your Australian business number (ABN) details. You must update your details within 28 days of becoming alert of changes.
Once you are registered your ABN details become part of the ABR. It is important that your details are up-to-date so that other businesses can access and verify your information, for example, that you are operating a business or the status of your GST registration.
Your ABN details are also used by a range of management agencies to plan for community services and infrastructure development that can help business.
What can be updated
- legal name of the entity, except for:
- individuals and sole traders who need to contact the ATO directly and
- companies in the business names register which need to contact the Australian Securities & Investments Commission (ASIC).
(ATO and ASIC will write the changes to update the ABR.)
- addresses – postal, business location, email
- ANZSIC – main business activity and industry code
- entity type – business structure, for example, private company to public company
- contact details
- associate details.
