How to update your business details
Last Updated: 18 October 2019
Find out who you need to notify when you make changes to your business to ensure you comply with your legal and tax obligations.
If you make changes to your business such as your business structure, name, or contact details, you need to tell all the stakeholders in your business and relevant agencies, organisations and governments.
The change in your business circumstance will dictate who you notify.
The Australian Taxation Office (ATO), Australian Securities & Investments Commission (ASIC) and the Australian Business Register (ABR) require you to report changes within 28 days.
3. Update your ABN details
If you’ve made changes to your business you’ll need to change your Australian business number (ABN) details on the ABR.
How to update your ABN details
You can update details:
- online through Australian Business Register
- through your registered tax agent or BAS agent
- by calling the Australian Business Register Infoline on 13 92 26
- by lodging a Change of registration details form (search for NAT 2943)
If you decide to close your business it’s important to cancel your ABN.
