Choosing the Right Business Structure: A Guide for Perth Business Owners

Starting a business in Perth involves several important decisions, from developing a business model to managing finances and understanding regulatory responsibilities. One decision that can have lasting consequences is choosing the appropriate business structure.

Whether you are launching a consulting practice, establishing a construction company, opening a retail business or planning to expand an existing operation, your structure can affect taxation, personal liability, administrative costs and how the business operates.

In Australia, four commonly used business structures are sole trader, partnership, company and trust.

Each has different advantages, limitations and compliance requirements.

The right business structure depends on your ownership arrangements, commercial objectives, financial circumstances, risk exposure and future plans. No single structure is suitable for every business.

This guide explains the key differences between common Australian business structures, their general tax and accounting implications and the factors Perth business owners should consider before making a decision.

What Is a Business Structure in Australia?

A business structure is the legal and operational arrangement through which a business is owned, managed and operated.

It determines or influences important matters such as who is responsible for business decisions, how income is taxed, what registrations are required and the extent of potential personal liability.

The four most commonly used Australian business structures are:

• Sole trader: An individual operates the business personally.

• Partnership: Two or more parties conduct business together.

• Company: A separate legal entity operates the business.

• Trust: A trustee holds and manages assets or business activities for beneficiaries under the applicable trust arrangements.

The Australian Government's business structure guidance explains that structure selection should consider costs, control, taxation, liability and administration.

Choosing a structure should therefore involve more than comparing potential income tax rates.

1. Sole Trader: A Common Starting Point for Small Businesses

A sole trader is an individual who owns and operates a business.

It is generally the simplest and least expensive of the four common structures to establish and administer.

Many freelancers, independent consultants, tradespeople and small service providers begin operating as sole traders.

How Does a Sole Trader Structure Work?

A sole trader controls business decisions and is personally responsible for the business's legal obligations.

The business is not a separate legal entity from its owner.

For income tax purposes, the sole trader generally reports business income and expenses through their individual tax return.

Business income is taxed under the applicable individual income tax rules.

Advantages of Operating as a Sole Trader

Straightforward setup

Compared with more complex structures, establishing a sole trader business generally requires less administration.

Direct decision-making

The owner can make business decisions without needing approval from other owners or company directors.

Simpler taxation arrangements

Business income is generally reported through the owner's individual tax return rather than a separate company tax return.

Lower ongoing administrative costs

Sole traders generally have fewer entity-specific reporting and compliance requirements than companies and trusts.

Disadvantages of a Sole Trader Structure

The most significant consideration is personal liability.

A sole trader is generally personally responsible for business debts and legal obligations.

This can expose personal assets to business-related risks.

The structure may also be less suitable for businesses seeking multiple equity owners or particular investment arrangements.

Example: A Perth Freelance Consultant

Consider a Perth marketing consultant starting a business independently.

The consultant has relatively limited startup expenses, does not intend to introduce other owners and wants straightforward administration.

A sole trader arrangement may be worth considering.

However, the consultant should still assess professional liability risks, tax obligations, insurance requirements and future plans before deciding.

2. Partnership: Running a Business With Others

A partnership generally involves two or more parties conducting a business together and sharing its income or losses.

Partnerships are sometimes used by professional service providers, family businesses and owners who want to combine resources.

The legal and taxation arrangements can vary depending on the type of partnership and applicable law.

How Does Partnership Taxation Work?

For a typical Australian tax law partnership, the partnership generally lodges an annual partnership tax return.

The partnership itself generally does not pay income tax on its net income. Instead, each partner reports their relevant share in their own tax return.

The partnership must maintain appropriate records and meet applicable registration and reporting obligations.

Advantages of a Partnership

Shared business responsibilities

Partners can contribute different skills, experience and resources.

Combined capital and expertise

Multiple participants may make it easier to establish and operate certain businesses.

Flexible commercial arrangements

A properly drafted partnership agreement can clarify the partners' respective contributions, responsibilities and profit-sharing arrangements.

Disadvantages of a Partnership

Potential personal liability

In an ordinary general partnership, partners can be personally responsible for partnership obligations, including liabilities associated with another partner's actions.

Disagreements between partners

Differences in commercial objectives, workloads and financial expectations can create disputes.

Ownership changes

Introducing or removing partners can create contractual, taxation and administrative consequences.

Why a Partnership Agreement Matters

A written partnership agreement can address matters such as:

• Ownership and capital contributions.

• Responsibilities of individual partners.

• Profit-sharing arrangements.

• Decision-making procedures.

• Admission of new partners.

• Dispute resolution.

• Exit and succession arrangements.

Legal advice is important when establishing these arrangements.

Example: Two Perth Tradespeople Starting a Business

Imagine two qualified electricians deciding to operate a contracting business together.

One brings established customer relationships, while the other contributes equipment and operational experience.

A partnership may be one possible structure.

However, both owners should understand the potential liabilities, tax obligations and consequences of disagreements before proceeding.

3. Company: A Separate Legal Entity

A company is a legal entity separate from its shareholders and directors.

In Australia, companies are registered with the Australian Securities and Investments Commission (ASIC) and must comply with relevant requirements under the Corporations Act 2001.

Companies can enter contracts, hold assets, incur liabilities and conduct business in their own name.

A proprietary limited company is a common structure used by Australian small and medium-sized businesses.

How Does Company Taxation Work?

A company generally lodges its own income tax return and pays income tax on its taxable income.

The applicable company tax rate depends on the company's circumstances and whether it satisfies the relevant requirements for a concessional rate.

Money received by a company does not automatically become the personal income of its shareholders or directors.

Payments to owners may involve salaries, dividends, loans or other arrangements, each with different taxation and compliance implications.

Advantages of a Company Structure

Separate legal identity

The company can own assets and enter agreements independently of its shareholders.

Generally limited shareholder liability

Shareholders' liability is usually limited, subject to relevant exceptions and circumstances.

Ownership arrangements

Shares can provide a framework for business ownership and introducing investors.

Business continuity

A company can continue operating despite changes in its shareholders or directors.

Disadvantages of a Company Structure

Higher establishment costs

Registering a company generally involves greater upfront expenses than establishing a sole trader business.

Ongoing compliance

Companies have ASIC obligations, corporate record-keeping requirements and other potential reporting responsibilities.

Director responsibilities

Directors must comply with legal duties and may face personal liability in certain situations.

Does a Company Protect Personal Assets?

A company can provide separation between business and personal liabilities, but that protection is not absolute.

For example, directors may become personally responsible for certain liabilities if they breach legal duties or applicable insolvency-related obligations.

Personal guarantees can also expose individuals to particular business debts.

A company should therefore not be viewed as a guarantee that personal assets are protected in every circumstance.

Example: A Growing Perth Technology Business

Consider a software development business planning to introduce additional shareholders and seek external investment.

The owners may consider a company structure because it allows ownership to be represented through shares.

However, the company would also need to comply with relevant corporate, taxation and administrative requirements.

4. Trust: Holding and Managing Business Assets for Beneficiaries

A trust is a legal relationship in which a trustee holds and manages property for beneficiaries according to the trust's terms and applicable law.

Trusts can be used in business and investment arrangements, but they are generally more complex to establish and administer.

Common arrangements include discretionary trusts and unit trusts.

How Does a Trust Work?

The trustee is responsible for administering the trust and acting in accordance with its legal obligations.

A trustee can be an individual or a company.

A trust normally operates under a trust deed that sets out relevant powers, responsibilities and beneficiary arrangements.

Unlike a company, an ordinary trust is not itself a separate legal entity.

How Is Trust Income Taxed?

Trust taxation can be complex.

Tax outcomes may depend on the type of trust, its income, the trust deed, beneficiary entitlements and applicable taxation rules.

In many circumstances, beneficiaries are assessed on relevant shares of trust income, while the trustee may be liable for tax in particular situations.

Business owners should not assume that trust arrangements automatically reduce tax.

Advantages of Trust Structures

Depending on the arrangement, possible features include:

• Flexibility in managing beneficiary interests.

• Separation of legal and beneficial ownership.

• Arrangements for holding business or investment assets.

• Succession and ownership planning possibilities.

These benefits depend on the trust deed, legal circumstances and applicable tax rules.

Disadvantages of Trust Structures

Greater complexity

Trusts generally require careful establishment and ongoing administration.

Trust deed requirements

The trustee must comply with the trust's governing terms and relevant law.

Specialist taxation rules

Trust income, distributions, losses and transactions may be subject to complex rules.

Potential liability considerations

An individual trustee may face personal liability, while using a corporate trustee involves additional corporate responsibilities.

Example: A Perth Family-Owned Business

A family planning to operate a business may consider whether a discretionary trust is appropriate.

However, the potential tax treatment, beneficiary arrangements, commercial risks and administrative costs require careful review.

Trust rules and government tax policy can also change, making current professional advice particularly important.

Sole Trader vs Partnership vs Company vs Trust: Comparison

The following table provides a general comparison of common Australian business structures.

The table is a starting point only. Actual consequences depend on the arrangement, relevant legislation and the business's circumstances.

5. Which Business Structure Is Best for Tax Purposes?

There is no universally best business structure for tax in Australia.

The most appropriate structure depends on business profits, how income will be used, ownership arrangements, eligible concessions and other circumstances.

For example, a sole trader's business income is generally taxed through their individual income tax return.

A company usually pays income tax separately, but distributing company profits to shareholders can create additional tax consequences.

A trust may have different taxation outcomes depending on the beneficiaries, entitlements and applicable law.

Why the Lowest Tax Rate Is Not the Only Consideration

Business owners should also consider:

• Legal liability.

• Setup and maintenance expenses.

• Administration and reporting obligations.

• How profits will be accessed.

• Ownership and succession plans.

• Business growth.

• Potential future restructuring costs.

Selecting a structure solely because one tax rate appears lower can overlook important consequences.

A professional comparison should consider the overall financial and legal implications.

6. How Business Structures Affect Accounting and Compliance

Each structure requires appropriate records, but reporting responsibilities differ.

Sole Trader Accounting

A sole trader generally needs to maintain records supporting business income and expenses and report relevant information through their individual income tax return.

Additional obligations can apply when registered for GST or employing staff.

Partnership Accounting

Partnerships generally need records supporting partnership income, expenses, allocations and partner interests.

Annual partnership tax reporting is commonly required.

Company Accounting

Companies must maintain suitable financial records and comply with applicable corporate and taxation obligations.

Depending on the company and circumstances, requirements may include ASIC registers, company tax returns and other reporting.

Trust Accounting

Trusts generally need records covering income, expenses, assets, beneficiary entitlements and distributions.

The trust deed and taxation rules can significantly affect reporting requirements.

Regardless of structure, accurate accounting records are fundamental to understanding business performance and meeting compliance obligations.

7. When Should a Perth Business Review Its Structure?

A business structure that was suitable at startup may not remain appropriate as operations change.

Reviewing the existing structure can be useful when the business reaches significant milestones.

Common Reasons to Review

Business growth

Revenue, employees and business assets may increase substantially.

Additional owners

The business may introduce investors or new partners.

Changing risk exposure

Contracts, borrowing arrangements and operational activities may create additional liabilities.

Succession planning

Existing owners may want to transfer or sell their interests.

Significant investments

The business may acquire property, equipment or another business.

Changing family or commercial circumstances

The business's ownership and financial priorities may evolve.

A periodic review can help business owners understand whether the current structure continues to support their needs.

8. Can You Change Your Business Structure Later?

Yes. Australian businesses can change their structure as they develop.

However, restructuring is not always straightforward.

For example, moving from a sole trader arrangement into a company may require changes to ownership, registrations, contracts and accounting records.

The transfer of business assets can potentially create tax or duty consequences.

Considerations Before Restructuring

• Whether assets need to be transferred.

• Potential capital gains tax consequences.

• GST implications.

• Western Australian transfer duty rules.

• Changes to business registrations.

• Existing finance and contractual arrangements.

• Employee obligations.

• Additional ongoing administration.

Certain tax rollovers or concessions may be available where specific conditions are satisfied, but they should never be assumed to apply automatically.

Business owners should seek professional advice before completing a restructure.

9. How an Accountant Can Help You Choose a Business Structure

Choosing a structure requires a practical understanding of business finances as well as relevant taxation rules.

An accountant can help owners assess how different arrangements may affect record keeping, tax obligations, reporting and future business decisions.

Areas an Accountant May Review

• Current and expected business income.

• Tax implications of different structures.

• Accounting and reporting responsibilities.

• Expected operating costs.

• Cash flow and financial objectives.

• Ownership arrangements.

• Potential restructuring consequences.

• Relevant tax concessions and eligibility requirements.

Legal advice may also be necessary for asset protection, contractual obligations, trust deeds and other legal matters.

Perth business owners looking for professional assistance can explore business accounting services in Perth through providers such as Investax, which offers business accounting, taxation and advisory support.

A qualified adviser can help explain the available options based on the actual circumstances of the business.

10. Common Mistakes When Choosing a Business Structure

Several misunderstandings can lead business owners to select structures that do not align with their needs.

Choosing Sole Trader Solely Because It Is Easy

Simple administration can be attractive, but business owners should also consider liability and long-term plans.

Assuming a Company Removes Every Personal Risk

Companies are separate legal entities, but directors can face personal responsibilities in certain circumstances.

Establishing a Trust Only to Reduce Tax

Trust taxation is complex, and benefits depend on the arrangement and applicable legislation.

Starting a Partnership Without Clear Agreements

Undefined ownership and responsibility arrangements can create disputes.

Ignoring Ongoing Compliance Costs

More complex structures generally involve additional administration and professional expenses.

Changing Structures Without Advice

Restructuring can create unintended taxation, duty and legal consequences.

Understanding these issues before committing to a structure is important.

Frequently Asked Questions

What is the best business structure for a small business in Australia?

There is no single best structure. Sole traders, partnerships, companies and trusts have different taxation, liability and administration characteristics. The appropriate option depends on ownership, risk, financial circumstances and business objectives.

Is it better to be a sole trader or a company?

A sole trader generally has simpler administration but personal responsibility for business liabilities. A company is a separate legal entity with additional compliance requirements and generally limited shareholder liability. The better option depends on individual circumstances.

Can a sole trader change to a company in Australia?

Yes. A sole trader can establish a company and transfer relevant business operations, subject to applicable requirements. The process can involve tax, duty, contract and registration consequences.

Does a company pay less tax than a sole trader?

Not necessarily. Companies and individuals are subject to different income tax rules. The overall outcome depends on profits, eligibility for applicable rates and how company earnings are ultimately used or distributed.

Is a trust a separate legal entity in Australia?

Generally, an ordinary trust is a legal relationship rather than a separate legal entity. The trustee holds and manages trust property. A corporate trustee is itself a separate legal entity.

Can two people operate a business as a partnership?

Yes. A partnership is one possible arrangement for two or more parties operating a business together. Partners should understand potential liabilities, tax requirements and the importance of clear agreements.

Does a business structure affect GST registration?

A business's GST obligations depend on relevant registration rules and the entity conducting the enterprise. The commonly applicable $75,000 GST turnover threshold is not determined simply by choosing a company, trust or sole trader structure. Special requirements and exceptions can apply.

Should I speak with an accountant before choosing a business structure?

Professional advice can help business owners understand the accounting and tax implications of different structures. A lawyer may also be needed to assess liability, ownership and other legal matters.

Conclusion: Choose a Structure That Supports Your Business Goals

Choosing a business structure is one of the most important decisions involved in starting or expanding a business in Perth.

Sole traders, partnerships, companies and trusts each have different characteristics, benefits and responsibilities.

A structure that works well for a small independent operator may not be suitable for a business with multiple owners, substantial assets or complex commercial arrangements.

Tax considerations are important, but they should be assessed alongside legal liability, operating costs, reporting requirements and long-term objectives.

The most suitable structure is one that supports the business's commercial needs while allowing its owners to understand and manage the associated responsibilities.

Before establishing or changing a business structure, seeking appropriate accounting, taxation and legal advice can help identify relevant risks and consequences.
