Making the transition from sole trader to company in Australia is one of the most significant structural decisions a business owner can make. Done at the right time and in the right order, it can reduce your tax bill substantially, protect your personal assets, and set you up for serious growth. Done without proper planning, it creates unexpected tax events, contract gaps, and compliance headaches that cost far more to fix than to prevent. This guide walks you through every step — from understanding when to make the switch, to the practical sequence of registrations, asset transfers, and contract novations that make the transition clean.
Why Transition from Sole Trader to Company?
The sole trader to company transition in Australia is driven by four compelling reasons: tax savings (company rate 25% vs personal rate up to 47%), limited liability (personal assets protected), credibility with clients and suppliers, and the ability to attract investors or sell the business.
Key Differences: Sole Trader vs Company Structure
| Feature | Sole Trader | Company (Pty Ltd) |
|---|---|---|
| Legal entity | Not separate — you and the business are the same | Separate legal entity |
| Tax rate | Personal marginal rate (up to 47%) | 25% (base rate) or 30% |
| Personal liability | Unlimited — personal assets at risk | Generally limited to share capital |
| Setup cost | Low — business name registration only | ASIC registration fee $597 + professional fees |
| Ongoing compliance | Minimal | ASIC annual review fee, financial reporting, director duties |
| Ability to sell | Asset sale only (complex) | Share sale or asset sale (more flexible) |

When Is the Right Time to Make the Switch?
Consider making the transition from sole trader to company when your net profit is consistently above $80,000–$100,000 per year; when you are taking on work with significant liability risk; when you plan to bring in a business partner or investor; or when a major client requires you to be a registered company. If profit is modest and liability exposure is low, staying as a sole trader is often the smarter short-term move. Our business advisory team can model the financial impact for your specific situation.
Step-by-Step: How to Transition from Sole Trader to Company in Australia
The sole trader to company transition must follow a specific sequence. Skipping steps creates tax exposure and contract gaps:
- 1Get professional advice first. The order of steps matters. Speak with a Chartered Accountant before you do anything — the tax and legal implications of asset transfers depend on your specific circumstances.
- 2Register your company with ASIC. Choose a company name, appoint at least one Australian resident director, choose a registered office address, and register at ASIC’s online portal. You receive an ACN on registration.
- 3Obtain an ABN and TFN for the company. Apply through the Australian Business Register. The company needs its own ABN separate from your sole trader ABN.
- 4Register for GST and PAYG withholding. If the company’s expected turnover will exceed $75,000, register for GST. Also register for PAYG withholding if you will pay yourself a director’s salary.
- 5Open a company bank account. The company must have its own account. Never mix personal, sole trader, and company funds.
- 6Transfer assets from sole trader to company. Must be done carefully to manage CGT and GST. The “going concern” GST concession and small business CGT concessions may apply — seek advice before proceeding.
- 7Novate existing contracts to the company. Client and supplier contracts are with you personally. They do not automatically transfer. Contact each counterparty and document novation in writing.
- 8Notify clients, suppliers, and your bank. Update invoicing, purchase orders, and bank payment details to the company’s name and ABN.
- 9Cancel sole trader registrations. Cancel your sole trader ABN, GST registration, and business name after — not before — the company is fully set up.
- 10Set up company bookkeeping and payroll. Establish your Xero or MYOB file under the company entity. Our bookkeeping and payroll team can handle this setup for you.
Tax Implications of the Transition
In the financial year you make the transition from sole trader to company, you will likely lodge both a sole trader and a company tax return. Company profits are taxed at 25% (base rate entity) rather than your personal rate — but to access those profits personally, you pay a salary (taxed at personal rates) or declare a franked dividend. The tax benefit accrues when profits are retained within the company. Once you pay yourself a director’s salary, superannuation at the current SGC rate (11.5%) is mandatory.
Transferring Assets: CGT and GST Considerations
CGT on asset transfer
Transferring business assets (equipment, goodwill, client lists) to the company is treated as a disposal by you and acquisition by the company. Small business CGT concessions — 15-year exemption, active asset reduction, retirement concession, rollover — may reduce or defer this liability. Specific eligibility criteria apply.
GST going concern concession
If you are transferring an entire business operation and both parties are GST-registered, the transfer may qualify as a “going concern” — no GST payable. This requires specific written agreement and must be correctly documented. Get advice before assuming it applies.
What Happens to Your Existing Contracts?
A company is a separate legal entity. Your sole trader contracts do not automatically transfer. You need to review every active contract, contact each counterparty, obtain written consent, and execute a deed of novation for each material contract. Update lease agreements, insurance policies, and finance agreements to the company name.
How Much Does the Transition Cost?
| Cost Item | Approximate Cost |
|---|---|
| ASIC company registration fee | $597 |
| ASIC annual review fee (ongoing) | $310/year |
| Accountant fees (transition advice + setup) | $1,000 – $3,000 |
| Solicitor fees (deeds of novation) | $500 – $2,000 |
| Bookkeeping system setup | $200 – $600 |
| Total (estimated) | $2,600 – $6,500 |
Common Mistakes to Avoid
- Registering the company before getting tax advice — the order of steps locks in your tax position.
- Continuing to invoice under the sole trader ABN after the company starts operating.
- Mixing personal and company funds — personal expenses paid through the company can be treated as unfranked dividends or Division 7A loans.
- Forgetting to update insurance — sole trader policies do not cover the company.
- Assuming contracts transfer automatically — they don’t.
Frequently Asked Questions: Transitioning from Sole Trader to Company Australia
When should I transition from sole trader to company in Australia?
When annual profit is consistently above $80,000–$100,000 (company tax rate of 25% beats your personal rate), when you need to limit personal liability, when bringing in a partner or investor, or when planning to grow significantly or sell the business.
Do I need a new ABN when I change from sole trader to company?
Yes. The company is a separate legal entity and requires its own ABN. Cancel your sole trader ABN once the company begins operating. ASIC issues an ACN on registration; you then apply for the company ABN and TFN through the ATO.
Can I transfer my sole trader business name to a company?
Not directly. Cancel the sole trader business name and re-register it under the company’s ACN, or let the company trade under its registered company name.
What are the tax implications of moving from sole trader to company?
Transferring assets can trigger CGT and GST events. Small business CGT concessions may apply. Get advice from a registered tax agent before transferring any assets.
How much does it cost to set up a company in Australia?
ASIC registration is $597. Professional fees for the transition add $1,500–$5,000+. ASIC annual review fees are $310 per year ongoing.
Can I be both a sole trader and have a company at the same time?
Yes, legally. But the activities of each structure must be kept completely separate — separate accounts, invoicing, and bookkeeping. Mixing them creates serious tax and liability risk.
Do I need to re-register for GST when I form a company?
Yes. The company is a new entity and needs its own GST registration. Cancel your sole trader GST registration and register the company if its turnover will exceed $75,000.
What happens to my sole trader contracts when I form a company?
They remain with you personally. You must formally novate each material contract to the company with written consent from the other party — including client contracts, supplier agreements, leases, and insurance.
How long does it take to transition from sole trader to company?
ASIC registration: 24–48 hours. Full transition including asset transfer, contract novations, registrations, and client notification: typically 4–8 weeks when done properly.
Does converting to a company affect my ability to claim tax deductions?
Some sole trader deductions are not available to companies. However, companies access different deductions — instant asset write-off, director salaries, family payroll. A Chartered Accountant can model the net tax impact before you switch.
