How to Get an ABN for Support Workers: A Complete Guide

If you’re a support worker looking to operate independently, subcontract through agencies, or work directly with NDIS participants, one of the first things you’ll need is an Australian Business Number (ABN). Having an ABN allows you to invoice clients, register as a sole trader, and legally run your support work as a business.

This guide walks you through exactly how to get an ABN, who needs one, and what to do after you receive it.
‍

What is an ABN?

An Australian Business Number is an 11- digit identifier used by the Australian Government to recognise your business. For support workers, an ABN is essential for:

• Issuing invoices.
• Receiving payments directly from participants or agencies.
• Registering as a sole trader.
• Meeting ATO (Australian Taxation Office) requirements.
• Working with online platforms and marketplaces.

It’s important not to confuse an ABN with other identifiers:

• TFN (Tax File Number): For personal tax.
• ACN (Australian Company Number): Only for registered companies.

Most support workers operate as sole traders, so you’ll simply need an ABN.
‍

Who Needs an ABN as a Support Worker?

You need an ABN if you:

• Work independently with NDIS participants (self-managed or plan-managed).
• Subcontract for disability or aged-care agencies.
• Offer private support services outside a standard employment contract.
• Are starting your own small care-support business.

Important: If you are an employee for a registered provider, you do not need an ABN. The provider handles tax, superannuation, and insurance. Only independent contractors or subcontractors need an ABN. You can read in detail about The Price Guide For Sole Traders on our website.

Requirements Before Applying for an ABN

Before you start, make sure you have:

• Your Tax File Number (TFN).
• Full personal details (address, DOB).
• Contact details (phone, email).
• Business structure - for support workers, choose sole trader.
• Business activity information, such as “Disability Support Services”.
• Business commencement date.

You must confirm that you’re running or intending to run a business. Support work is considered an enterprise if you’re providing services directly to clients.

• Track expenses for deductions

4. Get Insurance

Most independent support workers need:

• Public liability insurance
• Professional indemnity insurance

5. Complete Necessary Checks

Depending on your work, you may also need:

Taking these steps ensures that you are fully prepared to operate your business safely and legally.
