Company Registration Services in Adelaide, Done Properly
From $1,299 all-inclusive, with the $636 ASIC fee covered. We work out whether a company is the right structure for you before we register one, so you do not pay for a setup you do not need.
Do You Actually Need a Company Structure?
Most people asking about company registration have already decided the answer is yes. Often it is. Sometimes it is not, and nobody told them before they paid.
A company is a separate legal entity. It gives you limited liability and a flat 25% company tax rate for base rate entities. It also imposes an annual ASIC review fee of $342 for as long as the company exists, a director identification number requirement for every director, and a tax return requirement, whether or not you traded.
For some Adelaide business owners, that trade-off is clearly worth it. For a sole trader turning over $60,000 with no employees and no asset risk, it often is not. As Registered Tax Agents, we tell you which one you are before you commit, then handle the company registration end-to-end if a company is the right answer.
Business Structure and Registration Services
Registration is the last step, not the first. The decision that matters is which structure best fits your turnover, risk exposure, and plans for the next five years. We work through that with you, then register whichever entity the answer points to.
Company Registration
Full Pty Ltd setup for $1,299 all-inclusive, with the $636 ASIC fee covered. You get your ACN, company constitution, share structure, director ID guidance, and ABN and TFN registration. Lodged as a registered ASIC agent, usually within two business days.
Trust Registration
Discretionary and family trust setup from $660. Trusts are well-suited for asset protection and income distribution among family members. We draft the deed, advise on the trustee decision, and register the structure with the ATO.
Partnership Registration
Partnership setup from $599, covering ABN, TFN, and GST registration. Suits two or more people sharing profits and control. We explain joint liability clearly before you sign, because most people underestimate it.
ABN and GST Setup
ABN registration from $150 and GST registration from $55. Required once turnover passes $75,000, and worth registering earlier in some cases. We assess whether voluntary registration helps your cash flow.
Business Name Registration
Business name registration costs $149 for 1 year or $299 for 3. A business name is not a company and does not provide liability protection. If you only need a trading name, we will tell you rather than sell you a company.
Corporate Trustee for SMSF
Corporate trustee company registration for $1,299. Sole-purpose SMSF trustee companies qualify for a reduced $70 ASIC annual review fee, rather than $342. We set the constitution up so the company keeps that concession.
What Company Registration Costs in SA
ASIC increased its fees on 1 July 2026. Registering a proprietary company now costs $636, up from $611, and the annual review fee rose from $329 to $342. Those are government charges, and every provider pays the same amount.
Our company registration is $1,299 all-inclusive, and the $636 ASIC fee is included in that price.
You will find online services that register a company for a service fee of around $34 plus ASIC's $636. If all you need is a form lodged and you are certain a company is right for you, use them. What you are paying us for is the part they do not do: a Registered Tax Agent working out whether the structure is correct, setting the share structure up so you are not restructuring in two years, and being accountable for the advice.

Complex Structures: Trusts, SMSF, and Multi-Entity Setups
Some structures need more than a standard Pty Ltd. Corporate trustees, family trusts holding operating companies, and SMSF structures each carry rules that are expensive to get wrong. We handle the complex end so the structure holds up under ATO scrutiny.
Company as Trustee
A corporate trustee separates trust liability from you personally. Where the company acts solely as trustee of one SMSF, it qualifies for the $70 annual review fee. Start trading through it, and ASIC reclassifies it to $342.
Family Trust with Corporate Trustee
Common for asset protection and income distribution. The setup is the trust deed at $660 plus the trustee company at $1,299. We advise on whether the combined structure earns its ongoing cost.
SMSF Structures
SMSF setup from $1,150, with corporate trustee registration at $1,299 and deed registration at $660. Getting the sole-purpose test right at the constitution stage permanently protects the reduced ASIC fee.
Restructuring an Existing Entity
Moving from sole trader to company, or company to trust, has CGT consequences. We model the tax outcome before you move and apply small business CGT concessions and rollover provisions where available.
Deregistration and Reinstatement
Voluntary deregistration is $52 through ASIC. A dormant company still costs $342 a year, so deregistering is usually cheaper than leaving it on the register. Company reinstatement is $880 if you need one back.
Registered Office Service
Use our office address as your registered office for $110. ASIC correspondence reaches us, so annual review notices do not go missing and late fees of $102 or $428 do not accrue.
