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.

Questions worth asking before you start

Who actually does the work — a person or an AI tool?

A named person on our team owns your file and reviews everything that leaves it. Software does a real share of the grinding underneath it — coding, matching, flagging the obvious gaps — but nothing regulated happens without a person’s judgement, and nothing here is signed or filed by an algorithm.

Is there a filing or lodging step here?

No — sole trader setup is operational work inside your books, not something submitted to ATO. Where a filing does sit downstream of it, inside company formation more broadly, that stays with your registered BAS or tax agent, never with us.

Which software do you work in?

Whatever you already run. Most commonly QuickBooks, Xero, NetSuite, Sage, Zoho Books and a handful of others — we work inside your system rather than moving you onto one of our own.

How does this actually start?

A short, free read-only look at what you already have, and a written note on what we found. A scoping call decides the size of the engagement — nothing here commits you to anything.

What does it cost?

There is no published price for sole trader setup — it depends on volume, how many entities are involved, and how far behind the books are. We quote after the read-only review, which is free.

How does this fit with the rest of company formation?

Sole trader setup sits inside company formation, alongside Pty Ltd company registration, Australian subsidiary of an Indian company, Partnership setup. Most clients end up buying the category as a whole rather than one leaf at a time, but starting narrow is fine.

How much does it cost to register as a sole trader in Australia?

The ABN itself is free through the official Australian Business Register. The only government cost that applies is if you register a business name with ASIC ($47 for 1 year or $108 for 3 years), which is only required if you trade under a name other than your own.

How long does it take to get an ABN?

Most applications through abr.gov.au issue an ABN instantly online. A smaller share get flagged for manual review — usually triggered by an unclear activity description or a details mismatch — which can take up to 28 days.

Do I need a separate TFN as a sole trader?

No. Your existing individual Tax File Number doubles as the sole trader's tax identifier — there is no separate business TFN to apply for.

When do I have to register for GST?

GST registration becomes mandatory once your turnover reaches or is projected to reach $75,000 in any 12-month period, with a 21-day window from when you knew or should have known you'd cross it. Below that, registration is optional.

What happens if I don't register for GST once I cross $75,000?

You're required to register within 21 days of knowing you'll exceed the threshold. Not registering on time can mean owing GST on sales made after the trigger date even without having collected it, plus potential penalties — which is why we track the turnover trigger rather than waiting for it to be discovered later.

Do I need to register a business name?

Only if you're trading under a name other than your own legal name. If invoices, your website and your shopfront all use your own name, no separate business name registration is required. If you trade as anything else, it's a separate ASIC registration on top of the ABN.

Can you tell me whether a particular expense is tax-deductible?

No — that's a tax agent service under the Tax Agent Services Act 2009, and answering it for a fee requires Tax Practitioners Board registration, which we don't hold. We prepare the facts pack; your registered tax agent gives the advice.

Is a sole trader ABN the same as a business registration certificate?

There's no separate certificate — the ABN itself, verifiable on the public ABN Lookup register, is the registration. That's a deliberately lighter setup than jurisdictions where a proprietorship needs a distinct registration document on top of a tax ID.

What do you actually prepare versus what do I have to do myself?

We prepare and can lodge the ABN application, the business name registration if needed, and the GST/PAYG-withholding registrations once triggered. Anything that involves judging a tax treatment or giving structuring advice sits with your registered tax agent, not with us.

Do I need an ABN before I can invoice a client?

Yes, effectively — without an ABN, businesses paying you are required to withhold 47% under no-ABN withholding rules. Getting the ABN in place before the first invoice avoids that withholding entirely.

What if I want to hire staff as a sole trader?

Taking on your first employee is one of the triggers that brings PAYG withholding registration into play alongside GST — we queue that registration once a hire is confirmed rather than leaving it until the first pay run is due.
