BUSINESS REGISTRATION ADELAIDE
Registered Tax Agents who set up your business the right way from day one. Company, trust, partnership, ABN, GST and business name registration, handled in one appointment, with the structure decision worked through before anything is lodged.







GET THE STRUCTURE RIGHT BEFORE YOU REGISTER
The most expensive mistake in business registration is not a filing error. It is registering the wrong structure. A sole trader who should have started as a company pays more tax than they need to. A company set up when a trust was the right call cannot access the asset protection and income flexibility the owner wanted. Unwinding either one later costs far more than getting it right at the start.
Registration itself is the easy part. Anyone can lodge an ABN application or pay ASIC to register a company. What actually matters is the decision that comes before the lodgement: sole trader, partnership, company, or trust, and which combination of ABN, GST, PAYG and business name registration goes with it. That decision depends on your expected income, your liability risk, who else is involved, and what you plan to do with the profit.
We register businesses for Adelaide as Registered Tax Agents under Tax Practitioners Board accreditation. That means we work through the structure decision with you first, then handle every registration the chosen structure needs, in the correct order, in one coordinated setup rather than piecemeal across three providers.
Our pricing is fixed and all inclusive, with the government fees built in. An ABN is $150, a business name is $149 for one year, a company is $1,299 fully registered, and a trust is $660. You get one clear figure with nothing hidden, quoted before any work starts.
WHAT OUR SOLE TRADER TAX SERVICE COVERS
Every sole trader is different. A part-time consultant with one client and a laptop is a different return from a full-time tradie with a ute, tools, a home workshop, and quarterly BAS. What does not change is the standard: every deduction claimed and documented, GST and PAYG handled correctly, and the return lodged on time through the agent channel.
Company Registration
Pty Ltd company registered with ASIC, including the ACN, director IDs, constitution, and share structure. From $1,299 fully registered, ASIC fee included. The right call once profit is consistently high or you need limited liability.
Individual ABN Registration
Australian Business Number registered through the ATO for sole traders and individuals. From $150, with GST and PAYG registration handled at the same time if you need them.
Partnership Registration
Partnership ABN and TFN, partnership agreement guidance, and the business name registered to the partnership. From $599. For two or more people going into business together without incorporating.
Trust Registration
Discretionary, unit, or hybrid trust set up with a compliant deed, independent settlor, ABN and TFN. South Australia charges no stamp duty on trust deeds. From $660.
SMSF Registration
Self-managed super fund registered with a compliant trust deed, corporate or individual trustee, ABN and TFN, and ATO registration within the 60-day window. From $1,150.
Business Name Registration
Business name (formerly trading name) registered with ASIC after a name availability search across three registers. From $149 for one year or $299 for three.
What Our Clients Say (Real Adelaide Stories)
What order do business registrations happen in?
Business registrations follow a fixed order. Completing them out of sequence costs money to unwind.
- Choose the structure. Sole trader, partnership, company or trust. This decision drives tax treatment, liability and every registration that follows.
![icon]()
- Register the entity, where applicable. Companies and trusts must exist before they can hold an ABN.
![icon]()
- Apply for the ABN. No business name can be registered without one.
![icon]()
- Register the business name. Only required when the trading name differs from the personal or company name.
![icon]()
- Register for tax. GST once turnover reaches $75,000, and PAYG withholding once you employ staff.

Changing structure after registration means new registrations, a new ABN in some cases, and potential capital gains tax consequences on transferred assets. Structure advice at step one is the cheapest part of the process.
