  • Registering your business

    When you start a business you need to get an Australian business number (ABN) and a tax file number (TFN) if you don’t already have one.

    It's good to get a secure online credential so you can use our online services for business reporting.

    You may also need to register for:

    • goods and services tax (GST)
    • pay as you go withholding (PAYG)
    • fringe benefits tax (FBT).

    These other registrations depend on the type of business you're running.

    If you need help, phone us on 13 28 66.

    Getting a TFN

    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.

    Getting 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 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.

    Registering your business name

    Most businesses need to apply for a registered business name with the Australian Securities & Investments Commission (ASIC).

    You don’t have to do this if you use your own name as the business name.
