What Is an Australian Business Number (ABN)?
An ABN is a unique 11-digit identifier issued by the Australian Business Register (ABR) — the ATO's official business registry. Every enterprise operating in Australia must have one to legally invoice clients, register for GST, and interact with government agencies.
Whether you're a freelancer landing your first client, a tradie setting up sole trader operations, or launching a Pty Ltd company — your ABN is your legal business identity in Australia.
- Invoice clients without PAYG withholding deductions
- Register for GST (mandatory at $75,000+ annual turnover)
- Claim legitimate business tax deductions from the ATO
- Register an Australian business name with ASIC
- Apply for government contracts, grants and tenders
- Access ATO online services and ABR business portals

Who Needs an ABN?
Any entity carrying on an enterprise in Australia is entitled — and in most cases required — to hold an ABN.
Sole Traders
Freelancers, contractors, consultants and self-employed individuals operating under their own name or an ABN business name.
- Invoice clients without PAYG deductions
- ABN links directly to your personal TFN
- Register a business name via ASIC
- Claim legitimate business tax deductions
Companies
All Australian registered companies — Pty Ltd, public companies and incorporated bodies — require an ABN to operate legally and meet ATO obligations.
- Separate from each director's personal ABN
- Required for all ATO company obligations
- Needed to open a business bank account
- Prerequisite for company income tax returns
Partnerships
Business partnerships require their own ABN — independent from each partner's individual ABN — to invoice clients and meet ATO obligations.
- Partnership-specific ABN required
- Separate from each partner's personal ABN
- Required to lodge partnership tax returns
- Needed for GST and PAYG withholding
Trusts
Discretionary, unit, hybrid and family trusts each require their own ABN. The trustee lodges the application on behalf of the trust.
- Trustee registers on behalf of the trust
- Required for SMSF and family trusts
- Separate from the trustee's own ABN
- Needed for trust distributions and GST
GST Registration is Mandatory at $75,000+ Annual Turnover
Once your annual turnover reaches or is expected to reach $75,000 (or $150,000 for non-profit organisations), you must also register for GST. Numberz handles both your ABN and GST registration in a single lodgement — no separate forms, no double handling, no extra cost.
What You'll Need to Register Your ABN

The smarter way to register your ABN
Thousands of Australians have registered their ABN through Numberz. Our expert-guided process eliminates errors, maximises approval rates, and gets your number faster.
Same-Day Processing
Most ABN applications lodged through Numberz are processed by the Australian Business Register on the same business day. You receive instant email confirmation the moment your ABN becomes active.
All Business Structures Covered
Sole trader, Pty Ltd company, partnership, or trust — our guided wizard adapts to your specific structure and prompts only the information the ABR actually needs, reducing errors.
Direct ABR Lodgement
We lodge directly with the Australian Business Register via our registered agent portal — the same channel used by the ATO — so your application enters the system with priority handling.
GST Registration in the Same Application
If your turnover is at or approaching $75,000 ($150,000 for non-profits), we include GST registration in the same lodgement. No separate forms, no double handling, no extra wait.
Transparent Fixed Pricing
No hidden fees or surprise charges. You see the exact cost of your ABN registration service before you begin — and it never changes. Registering directly with the ABR itself is free.
Bank-Grade Security
Your identity and business details are transmitted over TLS-encrypted connections and stored with 256-bit AES encryption. We are bound by Australian Privacy Act 1988 obligations as a registered tax agent.
TPB Registered Tax Agent
Unlike DIY portals, every application is reviewed by a Tax Practitioners Board (TPB) registered professional before lodgement — maximising your approval rate and minimising the risk of manual ATO review.
