Should You Register as a Company or Sole Trader? A Tax & Accounting Guide for Australian Arborists
Published on January 21, 2026
You started with a business idea, grabbed an Australian Business Number and set up as a sole trader in your own name, handling pruning and stump grinding for locals in Queanbeyan. Fast forward a couple of years: you have a crew, equipment finance, and property managers asking about your business structure before signing contracts. With turnover pushing past the Goods and Services Tax (GST) registration threshold, currently $75,000 in GST turnover for most businesses, questions about sole trader vs company start feeling urgent.
What Actually Changes Between Sole Trader and Company?
Two of the most common business structures in Australia are sole trader and company, and arborists often start with a sole trader structure because it is the simplest and cheapest way to set up and run a business. You trade in your own name or under a business name, with no separate legal entity, which keeps things straightforward at first.
A company structure changes that by creating a separate legal entity, usually a proprietary limited company or Pty Ltd company. This Pty Ltd company can own business assets, enter contracts, hold a business bank account and rack up company debts, all separate from you. This separation is one of the key differences that makes company structures appealing for arborists with growing crews and higher‑risk jobs.

How Tax and Reporting Work for Each Structure
Tax reporting is where sole trader vs company really hits home for arborists juggling fuel costs, equipment write‑offs and crew super. The Australian Taxation Office treats business income differently based on your business structure, affecting everything from personal income tax rates to separate tax returns.
For a sole trader business structure, business income flows straight into your personal tax return, taxed at personal income tax rates on your taxable income. There is no company tax return or separate business tax return, but you still need detailed financial records to claim deductions and meet tax and superannuation obligations.
Company Tax Return and Personal Tax Return
A company structure adds layers to tax reporting:
The company lodges a separate tax return and pays company tax on its profits, often called corporate tax.
Any money you take out as wages or dividends goes into your personal tax return as personal income.
This setup can involve tax planning around company tax rate vs personal rates, but it requires more ongoing compliance, including annual review fees. Both sole traders and companies must register for GST when their GST turnover (current or projected over a 12-month period) reaches $75,000 or more, and registration must occur within the required timeframe set by the ATO. Both structures can claim eligible deductions, but companies usually place more emphasis on separating personal and business assets in practice.
Risk, Liability and Protecting Personal Assets
Arborists know risk: a falling branch, a claims dispute or a slow‑paying contractor can turn into business debts fast. With a sole trader structure, you have unlimited personal liability, meaning you are personally liable and personally responsible for financial or tax debts if the business cannot pay.
Personal assets like your home or savings can be used to settle business debts. There is no legal entity standing between you and creditors, which is why sole trader works best when business scale and risk are low.
Limited Liability in a Company Structure
Switching to a company business structure offers limited liability because the company is a separate legal entity:
Company debts belong to the company, protecting personal assets in many cases.
Directors may still face officers’ liability insurance needs or personal liability for certain tax debts.
For arborists with chippers, loaders and crew, this separation between personal and business assets reduces how much personal risk you carry. It also makes it easier to raise capital or present to insurers who prefer dealing with a Pty Ltd company.
Cash Flow, Banking and Day‑To‑Day Operations
A separate business bank account is essential no matter your structure, but it is even more critical in a company to keep company money distinct from personal income. Sole trader businesses often mix things in one account, making it harder to track business finances and pay tax accurately.
In a sole trader business, you can withdraw money freely, but you must set aside enough for tax obligations and business debts. Company structures treat the business account more formally: payments must be wages, expenses or dividends, not casual draws.
Handling Business Income and Debts
Both structures require you to pay business debts and meet legal obligations, but:
Sole trader: Simpler, with lower ongoing costs but higher personal risk.
Company: Higher ongoing compliance, including ASIC annual review obligations and company registration renewals, but generally better suited to scaling with staff. Regardless of structure, if you employ workers you may be required to hold workers compensation insurance under your state or territory’s rules.
Fringe Benefits Tax (FBT) may come into play where you provide certain non-cash benefits such as private use of vehicles to employees. This can apply whether you operate as a sole trader with employees, a partnership, trust or company, but in practice it is more commonly managed through company or trust structures, often with more formal processes.

Costs, Growth and When to Switch
Ongoing costs are a big factor: a sole trader has minimal setup costs and no ASIC annual review fee, which can be ideal for testing a business idea solo. Company structures have ASIC company registration fees, annual review fees which are indexed annually, and potentially higher accounting costs for a separate company tax return as well as your personal return.
As your arborist business grows, a company can support raising capital, hiring more crew and managing complex business structures. Small business owners often switch when personal liability feels too high for the business assets and income involved.
