What is sole trader setup?
ABN, business name and the registrations that switch on with revenue — the lightest structure, set up without gaps.
A sole trader is the default structure most Australians start in, and for good reason — the identifier that makes it official, an Australian Business Number, is free and usually issued the moment you apply online through the Australian Business Register. There is no separate company, no separate legal entity, no certificate to frame on the wall. The ABN plus your existing individual Tax File Number is the entire registration most sole traders will ever need, which is a genuinely simpler starting point than what founders elsewhere are used to.
The part that trips people up isn't getting the ABN — it's what has to happen around it before the first invoice goes out. If you're trading under anything other than your own legal name (a shopfront name, a brand, a website), that name has to be separately registered with ASIC as a business name, and it lapses if the 1-year or 3-year renewal is missed. If the business is going to turn over more than $75,000 in a financial year, GST registration with the ATO stops being optional. Neither of those triggers announces itself — the ABN application doesn't ask 'will you cross $75,000 next quarter,' and it's on you to be watching.

Sole trader setup in Australia
The ABN is free — anything sold around it for hundreds of dollars is a markup on a free process
Registering an ABN through the official Australian Business Register at abr.gov.au costs nothing and is usually instant. Third-party "assisted registration" services exist and charge for the same free process — worth knowing before paying for something the government hands out at no cost. Our lodgement work is prep and submission, not a paid substitute for a free government form.
GST registration is mandatory at $75,000 turnover, not a suggestion
Below $75,000 in GST turnover (current or projected across any 12-month period, not strictly the financial year), GST registration with the ATO is optional. At or above it, registration is a legal requirement with a 21-day window from when you knew, or reasonably should have known, you'd cross the threshold. We track the turnover trigger and queue the registration; whether a specific supply is taxable, GST-free or input-taxed, and what actually goes on the resulting BAS, is your registered tax agent's determination under TASA 2009 s.90-10.
A business name is a separate registration from the ABN, and it lapses
Trading under any name other than your own legal name — a shopfront brand, a website name — requires a separate ASIC business name registration ($47 for 1 year or $108 for 3 years), on top of and independent from the ABN. It is not renewed automatically; missing the renewal date lapses the name and opens it up for someone else to register. We put the renewal on a calendar rather than leaving it to memory.
Tax advice for a fee needs a TPB-registered agent — this isn't a formality
Preparing and lodging the ABN and business name forms is unregulated document preparation. The moment advice crosses into what deduction to claim, how to structure income, or what a GST treatment should be, it becomes a tax agent service under the Tax Agent Services Act 2009, and giving it for a fee without Tax Practitioners Board registration carries real exposure — a Federal Court case fined an unregistered preparer $230,000. We stop at the facts and the forms; a TPB-registered tax agent gives the advice.
What your registered BAS or tax agent receives from us
- A completed ABN application pack — eligibility confirmation, ANZSIC activity classification, and address details, ready for lodgement or your own review before submission.
- The business name registration, if trading under one, filed with ASIC and its renewal date calendared before the 1-year or 3-year term lapses.
- A turnover tracker flagging the point you are approaching the $75,000 GST threshold, so registration is queued inside the 21-day window rather than discovered after the fact.
- A GST and PAYG withholding registration pack, prepared and ready to lodge once the threshold trigger (turnover, or your first employee) is confirmed.
- An ABN Lookup confirmation once the ABN issues — the same public record a client, bank or supplier will check to verify you.
- A facts-and-documents pack for anything that reads as a tax-treatment question, handed to your registered tax agent rather than answered by us.
