Notify changes to your business
Your business will inevitably change and grow - changes in your business circumstances may result in a need to change your business structure, your legal or trading name, your address and contact details. These changes may affect your tax and other regulatory obligations.
Change of business structure
Changed business circumstances may require you to change your business structure. For example, you might start off as a sole trader, then take on one or more partners and form a partnership, and then later still register as a proprietary limited company. When you change your business structure you are required to apply for a new ABN.
Change of personal details
Depending on the circumstances, you may need to advise the Australian Taxation Office (ATO), the Australian Securities and Investments Commission and your state or territory government. Such changes could be to your postal, email or business address, main business activity, financial institution account information, or authorised contact person details.
Change your ABN details
You can change your ABN details with the ATO through:
- Online transaction, if you have an ATO digital certificate
- Phone the ATO Business Infoline on 13 28 66
- Mail - Obtain a copy of the change of registration details form.
- Through your tax agent.
