Notify changes to your business
Your business will inevitably change and grow over time as you respond to different market opportunities, economic factors and personal issues. For example, changes in your business circumstances may result in a need to change your business structure, legal or trading name, or address and contact details.
These changes may affect your tax and other regulatory obligations.
Change your business structure
Changed business circumstances may require you to change your business structure. For example, you might start 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 your personal details
If your personal details change, you may need to:
- update your registration details with the Australian Taxation Office (ATO)
- update your business name details with the Australian Securities and Investments Commission (ASIC)
- advise 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
- phoning the ATO Business Infoline on 13 28 66
- mail - visit the update your registration details page to order the form
- your tax agent.
Use ABN Lookup to check whether your ABN details are up-to-date.
