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 of 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 of personal details

Depending on the circumstances, you may need to advise the Australian Taxation Office (ATO), the Australian Securities and Investments Commission (ASIC) and your state or territory government when changing your personal details. Such changes could be to your postal, email or business address, main business activity, financial institution account information, or authorised contact person details.
