An Australian Business Number (ABN) is essential for almost any retail store operating in Australia.
Without an ABN, you cannot issue tax invoices, register for GST, or trade with other businesses.
This step-by-step guide covers everything a retail store owner needs to know about applying for, using, and maintaining an ABN.
What is an ABN and Why Does Your Retail Store Need One?
An ABN is an 11-digit unique identifier issued by the Australian Business Register (ABR) on behalf of the ATO.
It identifies your business to the government and other businesses.
Your retail store needs an ABN if:
- You want to register for GST (mandatory if turnover exceeds $75,000).
- You need to issue tax invoices to customers who claim GST credits.
- You want to register a business name with ASIC.
- You need to open a business bank account.
- You want to hire employees (for PAYG withholding).
- You wish to claim fuel tax credits or other business deductions.
Exception: If you are a hobby (not a business) with no profit motive, you may not need an ABN. But most retail stores are clearly businesses.
Step 1: Check Your Eligibility for an ABN
You are eligible for an ABN if:
- You are carrying on an enterprise (business activity) in Australia.
- Your enterprise has a commercial purpose (profit motive).
- You are not an employee (you are self-employed).
- You have an Australian Tax File Number (TFN) – for Sole Traders. Companies use their ACN.
Your retail store qualifies if you sell physical products (clothing, electronics, groceries, etc.) to customers, whether online, from a physical shop, or at markets.
Step 2: Gather Required Information
Before starting the online application, prepare:
- Your personal details: Full name, date of birth, residential address, TFN.
- Your business details: Proposed start date, business activity description (e.g., 'Retail sale of women's clothing').
- Business structure: Sole Trader, partnership, company (ACN needed), or trust.
- Your principal place of business address: Physical retail shop address (or home address if online-only).
- Your postal address.
- Estimated annual turnover.
- Whether you need to register for GST (if turnover exceeds $75,000, you must).
Step 3: Apply Online via the ABR (Free Service)
Applying for an ABN is free through the Australian Business Register website (abr.gov.au).
- Go to abr.gov.au and click 'Apply for an ABN'.
- Create a myGovID account (if you don't have one) – at least Standard identity strength.
- Answer questions about your business structure, activities, and entity type.
- Provide your personal TFN and identity documents (driver's licence, passport).
- Submit the application.
Most Sole Trader ABN applications are approved instantly or within 24 hours. Company applications may take up to 28 days if manual checks are required.
Step 4: Receive Your ABN and Confirm GST Registration (If Needed)
Once approved, you will receive:
- Your 11-digit ABN (e.g., 12 345 678 901).
- A confirmation letter from the ATO.
- Your GST registration status (if you elected to register).
Important: If your retail turnover is below $75,000, GST registration is optional. However, registering voluntarily allows you to claim GST credits on your business purchases (rent, inventory, utilities). Many small shops choose to register even if not required.
Step 5: Display Your ABN Correctly
Australian law requires you to display your ABN on:
- Tax invoices: Every invoice must show 'ABN: XXX XXX XXX XXX'.
- Receipts: For sales over $82.50 (including GST).
- Business letterhead and contracts.
- Your retail store's website (footer or contact page).
- Order forms and quotes.
You do NOT need to display your ABN on your physical shopfront signage or price tags.
Step 6: Understand Your Ongoing Obligations with an ABN
Having an ABN comes with responsibilities:
- Lodging Business Activity Statements (BAS): If registered for GST, you must lodge BAS monthly, quarterly, or annually. This reports GST collected and paid.
- Reporting income: Sole Traders report business income in their personal tax return. Companies lodge a company tax return.
- Keeping records: Maintain records of all sales, purchases, and expenses for at least 5 years.
- Updating details: Inform the ABR within 28 days if you change address, business structure, or cease trading.
Common ABN Mistakes for Retail Stores
- Mistake 1: Applying for an ABN as a Sole Trader but operating as a partnership. All partners must apply jointly.
- Mistake 2: Forgetting to cancel your ABN when closing the shop. Otherwise, you'll still need to lodge BAS or nil returns.
- Mistake 3: Using an ABN for personal purchases. You cannot claim GST credits on non-business items.
- Mistake 4: Not having an ABN but trading with other businesses. Other businesses must withhold 47% PAYG from payments to you if you don't quote an ABN.
Pro tip: Even if you're a small market stall or online Etsy seller, get an ABN. It costs nothing, adds professionalism, and allows you to buy stock from wholesalers (who almost always require an ABN).
What If Your ABN Application Is Refused?
ASIC/ATO may refuse if:
- You do not have a valid TFN.
- Your business activity is illegal or a hobby (not a genuine enterprise).
- You provide false information.
If refused, you can request a review or apply again with corrected information.
Final Checklist for Your Retail Store's ABN
- ✔ Applied for ABN via abr.gov.au (free).
- ✔ Decided on GST registration (mandatory if turnover > $75k).
- ✔ Display ABN on invoices, receipts, and website.
- ✔ Set up a business bank account using your ABN.
- ✔ Registered your business name with ASIC (if trading under a name other than your own).

With your ABN in hand, your Australian retail store can legally operate, invoice customers, claim tax credits, and grow with confidence.
