Sole Trader Tax Return — Melbourne & Australia-Wide
Optium Accountants prepares sole trader tax returns for self-employed Australians across all industries. Our CPA-qualified team identifies every deduction you are entitled to, ensures your return is ATO-compliant, and lodges accurately — so you keep more of what you earn.
What Is a Sole Trader Tax Return?
As a sole trader, you report your business income and expenses as part of your individual tax return (not a separate business return). Your net business profit is added to any other income — wages, investments, rental — and taxed at individual marginal rates.
This makes the sole trader tax return deceptively straightforward in appearance, but complex in practice. Correctly identifying business deductions, applying the right depreciation methods, handling GST-exclusive figures, and managing PAYG instalments all require care. Getting it wrong costs you money — either in overpaid tax or in ATO penalties for underpayment.
What We Do for Sole Traders
Sole Trader Tax Return Preparation
We prepare your complete individual tax return including all business income, expenses, and deductions — accurately reported in the right labels to avoid ATO queries.
Business Deduction Review
We review your income and expenses systematically to ensure all legitimate deductions are claimed — vehicle use, home office, tools, subscriptions, insurance, marketing, and more.
GST & BAS Reconciliation
If you are registered for GST, we ensure your business income and expenses in the tax return are GST-exclusive and reconcile with your BAS lodgements for the year.
PAYG Instalment Management
We review whether your PAYG instalments are set at the right amount to avoid a large tax bill or overpaying throughout the year.
Depreciation & Asset Write-Offs
We apply the correct depreciation methods for business assets — including the instant asset write-off where eligible — to maximise your deduction in the current year.
ATO Lodgement & Compliance
We lodge your return through our registered tax agent portal, giving you access to extended lodgement deadlines and professional review before submission.
Common Sole Trader Tax Deductions We Claim
Many sole traders miss legitimate deductions simply because they don't know what they can claim. Our accountants review your full expense picture against ATO rules to ensure nothing is left on the table.
Important: Deductions must be directly related to earning your business income and you must have records to substantiate them. We help you understand what qualifies and how to keep your records correctly going forward.
Sole Traders We Work With
We work with sole traders across a wide range of industries and income types, including:
Personal Services Income (PSI) Rules
If you are a sole trader earning income primarily from your personal skills, labour, or expertise — such as a contractor, consultant, or freelancer — the ATO's Personal Services Income (PSI) rules may apply. PSI rules can limit the deductions you are entitled to claim and affect how your income is reported.
Our accountants assess whether PSI applies to your situation and ensure your return is structured correctly. Getting this wrong is one of the most common ATO audit triggers for sole traders — and one of the most avoidable with the right advice.

Frequently Asked Questions — Sole Trader Tax Returns
Do I need an accountant to lodge my sole trader tax return?
You are not legally required to use an accountant, but a registered tax agent ensures you claim all eligible deductions, avoid common errors that trigger ATO queries, and access extended lodgement deadlines. For most sole traders, the tax saved easily outweighs the accounting fee.
What records do I need to provide for my sole trader tax return?
Typically: your income summary or accounting software export, bank statements, receipts for business expenses, vehicle logbook (if claiming car expenses), any ATO pre-fill data from MyGov, and details of any assets purchased or disposed of during the year.
How is a sole trader tax return different from an employee tax return?
A sole trader return includes a business schedule reporting gross business income, allowable deductions, and net profit or loss. Employee returns report salary and wage income. The deduction rules also differ — sole traders can claim a wider range of business expenses not available to employees.
Can I claim my home office if I run my business from home?
Yes. Sole traders working from a home office can claim a portion of occupancy expenses (rent, mortgage interest, rates) or use the ATO's fixed-rate method (67 cents per hour). We assess which method gives you the best outcome.
What is the tax-free threshold and does it apply to sole traders?
The tax-free threshold of $18,200 applies to individuals, including sole traders. However, if your business income pushes you above this threshold — combined with any other income — you will be liable for tax. PAYG instalments are used to pre-pay tax on expected business income throughout the year.
