Choosing the right business structure isn’t just a legal formality—it’s one of the most important decisions you’ll make as a business owner. The structure you choose affects your taxation, personal risk, growth potential, and even how attractive your business is to investors.
At Symmetry Accounting & Tax Pty Ltd, we often see business owners set up a structure once and never revisit it. But as your business grows, your structure should evolve too. Otherwise, you may be paying more tax than necessary or exposing yourself to unnecessary risk.
Let’s break it down in a way that’s easy to understand.
Why Your Business Structure Matters More Than You Think
Your business structure influences several key areas:
How much tax you pay
How well your personal assets are protected
Your ability to grow or bring in partners
Access to funding or investors
Your long-term exit strategy
Think of your structure like the foundation of a house. If it’s not built correctly, everything else becomes harder to manage later.
The 4 Main Business Structures in Australia
In Australia, there are four common business structures:
Sole Trader
Partnership
Company
Trust
Each has its own strengths and weaknesses. The right choice depends on your income, risk level, and future plans.
Sole Trader: Simple but Risky
This is the easiest way to start a business. You operate under your own name and ABN.
Pros:
Low cost to set up
Minimal paperwork
Easy to manage
Cons:
You are personally liable for all debts
Higher tax rates as income grows
Difficult to scale or attract investors
This structure works well for freelancers or small startups, but it can become inefficient as your income increases.
Partnership: Shared Responsibility
A partnership involves two or more people running a business together.
Pros:
Easy to set up
Shared workload
Flexible profit sharing
Cons:
Each partner is personally liable
Potential for disputes
Profits taxed at individual rates
While partnerships can work well initially, they don’t offer strong protection unless combined with other structures.
Company: A Professional and Scalable Option
A company is a separate legal entity, meaning it exists independently from its owners.
Pros:
Limited liability protection
Lower corporate tax rates
Easier to attract investors
Stronger professional image
Cons:
More complex and costly to manage
Ongoing compliance requirements
Less flexibility in profit distribution
For many growing businesses in Perth, especially those generating higher profits, a company structure can be a smart move.
Trust: Flexibility and Strategic Advantage
Trusts are often used for taxation planning and asset protection.
Pros:
Flexible income distribution
Strong asset protection
Useful for family businesses
Supports long-term wealth planning
Cons:
More complex to manage
Requires careful administration
Needs expert business advisory support
Trusts are particularly useful when combined with other structures, especially for families and growing enterprises.
Company vs Trust: Which One is Better?
This is a common question—but the answer isn’t straightforward.
A company offers stability and lower tax rates
A trust offers flexibility and tax planning opportunities
In many cases, the best solution is a combination of both.
A common structure used by successful businesses is:
A company that runs the business
Owned by a trust
Managed by a corporate trustee
This setup can provide both flexibility and protection when done correctly.
How Taxation Works Across Structures
Understanding taxation is key when choosing a structure:
Sole traders & partnerships: taxed at personal rates (up to 45%)
Companies: taxed at a fixed rate (often 25%)
Trusts: income distributed and taxed at individual rates
Each structure offers different opportunities for tax planning. That’s why working with experienced accounting professionals is essential.
Asset Protection: Often Overlooked but Critical
Many business owners focus only on tax—but asset protection is just as important.
If you’re a sole trader and something goes wrong, your personal assets (like your home) could be at risk.
Structures like companies and trusts help create separation between your personal and business finances.
Planning for Growth, Investors, and Exit
If you plan to grow your business, bring in investors, or eventually sell, your structure matters.
Investors prefer companies
Buyers prefer clear ownership structures
Banks prefer formal entities
A well-structured business is easier to scale and more attractive in the market.
When Should You Change Your Business Structure?
You might need to restructure if:
Your profits exceed $200,000
You’re hiring employees
You’re taking on more risk
You want to bring in investors
You’re planning for succession
Restructuring isn’t a mistake—it’s a natural part of growth.
Common Mistakes to Avoid
Many business owners make these errors:
Choosing the cheapest option without thinking long-term
Copying someone else’s structure
Staying as a sole trader for too long
Not reviewing their structure regularly
Regular reviews with a business advisory expert can help avoid these pitfalls.
How SMSF Can Fit into Your Business Strategy
While not a business structure, an SMSF (Self-Managed Super Fund) can play a role in your overall financial strategy.
For example, some business owners use SMSFs to invest in commercial property used by their business. This can create long-term wealth and tax advantages when structured correctly.
However, SMSFs are complex and require professional guidance.
How to Know If Your Structure Is Right
Ask yourself:
Am I paying more tax than necessary?
Are my personal assets protected?
Can my business grow easily in this structure?
Would investors or buyers find this appealing?
If you’re unsure about any of these, it may be time for a review.
The Strategic Role of Business Advisory
Choosing the right structure isn’t just about compliance—it’s about strategy.

A proactive approach can save you significant time, money, and stress.
