Sole trader vs Pty Ltd: key differences
The two structures differ in one critical way. A sole trader and their business are the same legal entity. A Pty Ltd company is a separate legal entity entirely.
Knowing this is the starting point for changing from a sole trader to a company. As a sole trader, your personal assets are fully exposed if the business encounters trouble. Under a Pty Ltd structure, your liability is generally limited to company assets.
Sole traders pay income tax at personal marginal rates, up to 45%. Eligible small businesses pay a company tax rate of 25%
Signs it is time to make the switch
Not every sole trader needs to incorporate. Here are clear signals that a change from sole trader to company makes sense:
- Your profit is consistently high enough that the company tax rate saves you money
- You're taking on bigger clients or contracts with significant liability exposure
- You want to bring in co-founders, investors, or employees
- Clients or lenders require a company structure before engaging
- You plan to scale, expand, or eventually sell the business
Benefits of moving to a Pty Ltd company
Incorporating offers more than just liability protection. There are strong financial and operational reasons for changing from a sole trader to a company. The key advantages include the following:
- Limited liability protects your personal assets from business debts
- A lower company tax rate of 25% for eligible small businesses
- Improved credibility with clients, suppliers, and lenders
- The ability to issue shares and attract investors
A Pty Ltd structure also makes succession and exit planning cleaner.
Costs to consider before you transition
Transitioning is not free, so budget carefully before you start. Typical costs include:
- ASIC company registration: around AUD $576
- ASIC annual review fee: AUD $310 per year
- Legal and accounting fees: AUD $1,000 or more
- Stamp duty on asset transfers (varies by state)
- Admin costs for updating invoices, insurance, and marketing materials
How to transition from sole trader to Pty Ltd
The process of changing from a sole trader to a company is simpler than it sounds. You cannot convert your existing ABN. You're creating a new legal entity and transferring your business across to it.
Step 1: Get professional advice
Speak with an accountant and a lawyer first. A restructure involves tax events, contract transfers, and compliance obligations. Timing it to the end of a financial year helps simplify the process.
Step 2: Choose and check your company name
Check name availability at asic.gov.au. Your company name must end with "Pty Ltd." Consider filing a trade mark with IP Australia to protect your brand.
Step 3: Register your company with ASIC
Register your Pty Ltd through business.gov.au. You'll need director details, a shareholder structure, and either a company constitution or the Corporations Act replaceable rules. ASIC issues an ACN within 1 to 2 business days.
Step 4: Apply for a new ABN for the company
Once you have your ACN, apply for a new ABN at abr.gov.au. You cannot convert an ABN to an ACN.
Your sole trader ABN is personal. The company must apply for its own as a separate legal entity.
Step 5: Register for GST and other tax obligations
Register for GST if the company's annual turnover is expected to reach AUD $75,000 or more. Register for PAYG withholding if you're paying yourself a salary or employing staff.
Step 6: Open a business bank account in the company name
Your company must have its own bank account. Open a dedicated account in the company's legal name using the new ABN and ACN.
Step 7: Transfer assets, contracts, and licences
Assets like equipment, IP, and goodwill must be formally transferred to the company. Client and supplier contracts need to be novated or re-signed. Licences and permits may need to be re-applied for separately.
Step 8: Transfer or re-register your business name
Transfer your registered business name to the company via ASIC or the ABR. If you don't, it remains under your personal name.
Step 9: Notify clients, suppliers, and stakeholders
Update clients, suppliers, and lenders with the company's new legal name, ABN, ACN, and bank details. Refresh invoices, contracts, and your website. Notify the ATO that your sole trader ABN is no longer trading.
Step 10: Cancel your sole trader ABN
Once all operations have moved to the company, cancel your sole trader ABN through the ABR. Complete all outstanding obligations first.
Tax implications of transitioning
Transferring assets to a new company can trigger Capital Gains Tax (CGT). Depending on how long you've held those assets, the gain could be significant. This is why professional advice is essential before you start.
Companies pay a flat rate of 25% for eligible small businesses. Sole traders pay progressive personal rates up to 45%. You'll also pay yourself a director's salary, which is a separate taxable income event.
Small Business Restructure Rollover (SBRR)
If your business has an aggregated annual turnover under AUD $10 million, the Small Business Restructure Rollover may apply. The SBRR lets you transfer active business assets to a new entity without triggering an immediate CGT liability.
Active assets include CGT assets, trading stock, depreciating assets, and revenue assets. The restructure must be genuine and driven by business reasons, not tax avoidance.
Economic ownership must also stay the same. If you're a sole trader restructuring into a company, you must hold 100% of the shares. Speak with your accountant to confirm eligibility.
