Structure is a tax decision and a governance decision
Australia’s main business structures are sole trader, partnership, company, and trust. The choice affects how income is returned, who is responsible for tax debts, what records must be kept, whether separate tax registrations are needed, and how profits can be extracted. A structure should not be selected solely because one option appears to offer a lower headline tax rate.
A sole trader is generally the simplest structure. Business income and expenses are reported in the individual’s tax return, and the individual remains personally responsible for business debts. This can be suitable for a low-risk business operated by one person, but it may become less attractive as employees, investors, retained profits, or significant commercial liabilities arise.
A partnership generally involves two or more people carrying on a business together. The partnership has its own reporting obligations, but the partners are generally assessed on their shares of the partnership’s net income. A written partnership agreement should address contributions, decision-making, drawings, ownership of assets, dispute resolution, and what happens if a partner leaves.
Companies: separation, administration, and director exposure
A company is a separate legal entity. It generally has its own TFN and tax obligations, may be entitled to an ABN, and must meet additional reporting and governance requirements. A company can distribute profits through dividends, potentially with franking credits, but private use of company money or assets can create tax consequences.
Limited liability is not absolute. Directors may face personal exposure under director-penalty rules for certain unpaid tax and superannuation liabilities. Directors must also obtain a director identification number before appointment. Incorporation therefore requires ongoing compliance systems, not just a one-time registration.
Trusts: flexibility requires disciplined administration
Trusts can provide flexibility in distributing income and holding assets, but the trust deed is central. The deed and variations should be properly executed, retained, and reviewed. Trustees must understand the deed’s rules for calculating income, identifying beneficiaries, and making valid resolutions. A distribution that is inconsistent with the deed or made late can produce unexpected tax outcomes.
Business money should also be handled carefully. Salary, wages, directors’ fees, distributions, loans, and private use of business assets are not interchangeable. Companies and trusts should maintain contemporaneous records, comply with PAYG withholding where required, report through the appropriate channels, and meet superannuation obligations for eligible workers.
A pre-launch decision framework
- Identify whether the business has material personal-liability or asset-protection risks.
- Estimate whether profits will be withdrawn or retained for expansion.
- Consider the number of owners and how ownership may change.
- Map payroll, PAYG withholding, GST, superannuation, and reporting obligations.
- Budget for ASIC, accounting, legal, tax, and annual administration costs.
- Confirm how business assets and intellectual property will be owned.
- Obtain professional advice before transferring an existing business into a company or trust, because the transfer can itself have tax and CGT consequences.
The best structure is the one that fits the commercial purpose and can be administered correctly over time. A structure that is theoretically tax-effective but poorly documented can create greater cost and risk than a simpler alternative.
