The right business structure in Victoria depends on what can go wrong, who shares the profits, whether investors will ever come in and what happens on sale. A sole trader has unlimited personal liability, partners are jointly liable, a company generally limits shareholders' liability to their shares, and a discretionary trust offers flexible income distribution and a layer of asset protection. Here is how they compare, and how we help.

When does trading as a sole trader make sense?
Trading as a sole trader means the business is simply you: an ABN, perhaps a registered business name, and away you go. Setup is near-instant and costs almost nothing; reporting is your personal tax return. The price is unlimited personal liability: every business debt and every claim is yours, reaching your house and savings. Profits are taxed at your marginal rate, with no ability to share income or retain profits at lower rates. Sensible for low-risk services testing an idea; uncomfortable the day you hire staff, sign a lease or supply anything that can fail expensively.
What are the risks of a partnership?
A partnership arises when people carry on business in common with a view to profit, in Victoria under the Partnership Act 1958. It is cheap and flexible, and profits flow straight to the partners' returns. The structural flaw is joint liability: each partner can bind the firm, and each is personally exposed to the partnership's debts, including those created by the other partner. A written partnership agreement covering decisions, money, disputes and exits is not optional paperwork; it is the difference between a disagreement and a catastrophe. Many groups that begin as partnerships mature into companies or trusts once real value exists.
What does a company give you, and what does it ask of you?
A proprietary limited company is a separate legal person. It owns the assets, signs the contracts, employs the staff; its shareholders' liability is generally limited to their shares. Companies pay tax at the corporate rate, which for most trading small businesses is lower than the top personal rates, allowing profits to be retained and reinvested. Ownership is divisible into shares, which is what makes investors, employee equity and staged sales possible.
The obligations are real: registration and annual fees to ASIC, statutory records, and directors' duties. Those duties, care and diligence, good faith and no insolvent trading, carry personal consequences. Every director now needs a director identification number, and must generally apply for one before appointment. And limited liability has practical limits: landlords and banks routinely demand personal guarantees from small-company directors, which quietly re-connects the company's risk to your home unless negotiated. Read our guide to directors' duties in Victoria.
When does a trust suit a business?
A discretionary trust, often called a family trust, does not exist as a person; a trustee, often a company, holds the business or investments for a family group, deciding annually how income is distributed among them. The attractions are flexible income distribution and a layer of asset protection, since beneficiaries own nothing until distributions are made. The constraints: trusts must generally distribute profits each year, since profit kept in the trust is taxed at a penal rate; losses are trapped inside; banks find them fiddly; and outside investors mostly refuse them. Unit trusts suit some joint ventures; discretionary trusts more often hold assets or operate family businesses than scale-up ventures.
How do structures combine as a business grows?
Mature structures are usually combinations: a trading company owned by a family trust; premises or intellectual property held in a separate entity and licensed to the trader; a corporate trustee with a nominal-asset company shielding the humans. The design principle is simple: separate the assets from the risk. The execution is where legal and tax advice must be in the same room. We work alongside your accountant so the legal structure and the tax position pull in the same direction.
How do you choose the right structure?
- What can go wrong, and how expensive is it? Higher operational risk argues for a company sooner.
- Who shares the profits? A family with mixed incomes points towards a trust; a solo founder chasing investors points to a company.
- Will outside money ever come in? Investors buy shares. Structure for the destination, not just the departure.
- What happens on sale? Structure affects both the tax on your exit and how cleanly a buyer can acquire.
- What does simplicity cost you? Sometimes nothing: a low-risk consultant may rationally stay simple for years.
Can you change structure once you are trading?
Most businesses outgrow their first structure. Moving from sole trader or partnership into a company or trust is routine work, and rollover concessions can defer tax on the move when the change is genuine restructuring rather than disguised sale. The worst path is drift: carrying a grown business's risks on a start-up's structure because changing felt like admin. If the last structural conversation predates your current turnover, it is due.

Quick answers for founders
Can I just start as a sole trader and fix it later?
Often, yes: that is a rational sequence for low-risk ventures, and restructure pathways exist. The mistake is not starting simple; it is staying simple after hiring staff, signing a lease or taking real commercial risk.
Does a company protect me completely?
No. Directors remain personally exposed for insolvent trading, unpaid employee entitlements in defined cases, some tax debts under director penalty notices, and anything they personally guarantee. A company narrows risk; conduct and guarantees decide the rest.
Trust or company for my family business?
Usually a question of who takes the profits and how stable they are. Flexible family distributions favour a trust; retained earnings, outside investors and employee share plans favour a company. It is a joint decision for your lawyer and accountant.
What does setting up or changing a structure involve?
We establish companies and trusts, draft the agreements that make co-ownership safe, including shareholder agreements, review leases and supplier terms in the new entity's name, and coordinate the whole move with your accountant. Setting up a proprietary company is a fixed fee of $1,210, including GST and the registration fee charged by the Australian Securities and Investments Commission, whose website sets out the current registration requirements and fees. Other defined work is quoted as a fixed fee before we start, and our commercial law page describes it.
Before the first meeting, it helps to have three things ready: a short description of what the business does and who owns it now, a sense of who might need to come in later, whether that is an investor, a family member or a key employee, and the most recent financial statements, or a realistic forecast if the business is new. Your accountant's view covers tax, and ours covers liability, control and exit, so the best results come when both advisers are in the room from the start and the structure is chosen once, on the full picture.
Is there one right structure?
There is no universally right structure, only the right structure for this business, this family and this risk, reviewed as each of those changes. Choose deliberately at the start, revisit at every growth milestone, and treat the modest cost of restructuring as what it is: insurance priced far below the risks it retires.
