Keeping Your ABN Up-to-date
It's easy to overlook updating your ABN details on the Australian Business Register (ABR), but keeping this information current is essential. Your ABN details are used by government agencies and emergency services to identify businesses in need of support, particularly in times of crisis.
If your details are outdated, you could miss out on grants, financial assistance, or critical updates that impact your business.
Why Updating Your ABN Is Important
Ensuring your ABN details are accurate helps:
The right people have the correct permissions to act on behalf of your business.
Government agencies have up-to-date information to provide relevant support.
Your business is prepared for new government services as they become available.
To stay compliant and avoid missing key opportunities, review and update details such as:
- Authorised contacts
- Business location (not your Tax Agent or BAS Agent’s address)
- Postal address
- Email and phone number
Review Your Business Structure
It’s worth having a chat with your BAS Agent or Bookkeeper about your business structure.
- Do you have multiple ABNs? Are they still active?
- If a business entity is no longer operating, cancel the ABN to avoid compliance issues.
- If your business structure has changed, ensure your ABN is still valid—otherwise, apply for a new one.
Your Obligations as an ABN Holder
As an ABN holder, you must notify the ABR within 28 days of any changes to:
Business name
Address
Contact details
If the ABR contacts you for verification, you’re required to respond promptly. If you’re no longer in business, request ABN cancellation once all tax obligations are met.
