This page provides an overview of the registrations you may need when starting a business and information about getting a secure online credential for business reporting.
When you start a business you need to get an Australian business number (ABN) and a tax file number (TFN).
You may also need to register for:
- goods and services tax (GST)
- pay as you go (PAYG) withholding
- fringe benefits tax (FBT).
These other registrations depend on the type of business you're running, refer to Registering for GST and other taxes.
If you need help, phone us on 13 28 66.
All businesses need a TFN. If you're operating your business as a sole trader, then you can use your personal TFN. For other business structures, you can get a TFN when you apply for an ABN.
An ABN is the number your business uses when dealing with other businesses, government and us.
You need an ABN to operate in the GST system and claim GST credits. You must include it on your invoices. If you don't, other businesses will withhold tax at the highest rate from any payments they make to you.
To get an ABN:
- Apply onlineExternal Link through the Australian Business Register
- phone us on 13 92 26
- apply through a registered tax or BAS agent.
When you're applying for an ABN, you can register your business name and taxes like GST and PAYG withholding at the same time (if you need to).
If your business details change – for example, if you change your address or authorised contact person – you must advise us within 28 days.
Refer to Update your details.
