What is an ABN?
An Australian Business Number (ABN) is a unique 11-digit identifier for your business. For locum doctors, having an ABN signifies that you are operating as a sole trader or through a company, rather than as an employee. This distinction is crucial for managing your business dealings with hospitals and clinics.
The ABN is essential for invoicing and tax purposes. It allows you to be recognised by the government and other businesses, ensuring that your professional activities are properly documented and compliant with Australian regulations.

Why do locum doctors need an ABN?
Locum doctors require an ABN for several reasons. It allows direct invoicing for services rendered, providing control over income and expenses. This flexibility is ideal for doctors who wish to work with multiple hospitals or clinics without being tied to a single employer.
Without an ABN, locum doctors might be subject to PAYG employment, which can restrict flexibility and potentially lead to higher tax withholdings. Therefore, obtaining an ABN is a critical step for any doctor considering locum work.
💡Tax Planning
Setting aside funds for tax and superannuation is crucial for locum doctors.
How do you get an ABN as a locum doctor?
Step 1: Visit the Australian Business Register (ABR)
Begin by visiting the official Australian Business Register website at abr.gov.au. Click on "Apply for an ABN" and follow the online prompts to start your application.
Step 2: Choose Your Business Structure
Most locum doctors find that registering as a sole trader is the simplest option. However, you can opt to set up a company (Pty Ltd) if you plan to expand or split income for tax purposes in the future.
Step 3: Enter Your Details
You'll need to provide your Tax File Number (TFN), full name, address, and business activity (select "medical services" or "locum doctor"). Also, indicate the date you started or plan to start your locum work.
Step 4: Confirm GST Registration
If your annual income is expected to exceed A$75,000, you must register for GST. This involves adding 10% GST to your invoices and submitting a Business Activity Statement (BAS) quarterly to pay this tax. It's advisable to register for GST upfront to streamline your financial management.
Step 5: Submit and Record Your ABN
Upon approval, you'll receive your ABN instantly. Keep this number secure and include it on all invoices sent to hospitals or agencies.
Registering for GST upfront simplifies financial management for locum doctors.
