Choosing Your Legal Structure in Australia: An Overview

Choosing the right legal structure for your business is one of the first significant decisions you will make. The structure affects your liability, your tax position, your control over the business, and how easy it will be to attract investment or ultimately sell. Different structures suit different stages and circumstances, and the right answer is rarely "the cheapest option to set up.**"

Sole trader

A sole trader is the simplest business structure. As a sole trader, you control and manage the business, and you are legally responsible for all aspects of it. It is inexpensive to set up and gives you full control over your assets and decisions.

Liability. Sole traders are personally liable for their business's debts. If the business fails, your personal assets could be used to pay the business's debts. This is the most significant downside.

Tax. Sole traders pay tax at their individual tax rates and can offset business losses against other income. As income grows, this becomes less efficient than corporate structures.

Control. As a sole trader, you have full control over the business, but you also bear full responsibility.

Sole trader status suits the earliest stage of a business, particularly where the activity is low-risk, the business is testing the model, and significant assets are not at risk.

Partnership

A partnership is an association of people or entities who carry on a business together (or receive income jointly). It is relatively simple to set up and offers more financial resources than a sole trader since profits and losses are shared among partners.

Liability. Similar to sole traders, partners are personally liable for the debts of the business. Each partner can be responsible for the actions of the other partners (joint and several liability). This is a substantial risk.

Tax. Partnerships do not pay income tax themselves. Instead, each partner pays tax on their share of the net partnership income at their individual rates.

Control. Control of the business is shared among partners. Disagreements can affect the business significantly. A clear partnership agreement is essential.

Partnerships are common in professional services and family businesses, but the unlimited liability and the joint-and-several risk make them less attractive in most other contexts.

Company (proprietary limited)

A company is a separate legal entity, which means it has the same rights as a natural person. It can incur debt, sue and be sued. Most Australian businesses are structured as proprietary limited companies (Pty Ltd).

Liability. A company's shareholders have limited liability and are not generally liable for the company's debts (subject to specific exceptions, such as personal guarantees, breach of directors' duties, or insolvent trading).

Tax. Companies pay company tax at the corporate rate, separate from personal income tax rates. This can be more efficient at higher income levels and provides flexibility for retaining earnings.

Control. Control depends on the shareholding structure. Directors manage the company, while shareholders have voting rights on major decisions. There are more regulations and reporting requirements than for sole traders or partnerships.

Pty Ltd companies are the default structure for most growing businesses. They balance limited liability, tax efficiency and recognition by customers, suppliers and investors.

Trust

A trust is an entity that holds property or income for the benefit of others. In a business context, trusts are typically used for asset protection and tax planning, often in combination with a company.

Discretionary trust (also known as a family trust): the trustee has discretion to distribute income and capital among a class of beneficiaries (often family members).

Unit trust: beneficiaries hold defined units, with rights to a defined share of income and capital.

Liability. Depends on the type of trust. In a discretionary trust, the trustee is personally liable for the trust's debts (although usually a corporate trustee is used to limit personal liability). In a unit trust, both trustees and unit holders may have exposure.

Tax. Trusts do not pay tax themselves. They are required to pass on their income to beneficiaries, who pay tax at their personal rates. This provides flexibility for distributing income to beneficiaries on lower marginal rates.

Control. Trustees control the trust and its assets. Beneficiaries do not have direct control over the trust's assets, although they may have rights to enforce the trust deed.

Trusts are commonly used by family businesses, investors, and as part of broader group structures.

Combination structures

Many businesses use combinations: a Pty Ltd trading company with a discretionary trust as its parent, or a corporate group with multiple subsidiaries. These structures balance the benefits of different forms.

Choosing the structure

The right structure depends on:

• The nature of the business and its risk profile
• The industry and any specific regulatory requirements
• The size and growth plans of the operation
• The owners' tax positions
• The need to attract external investors
• The exit pathway (sale, IPO, succession)

There is no single "right" structure. The best answer is tailored to the specific circumstances.

Structures change over time

Most successful businesses change structures as they grow. The structure that works at $500k of revenue is rarely the structure that works at $50m. Plan for evolution.
