What is a sole trader tax return?

A sole trader tax return is not a separate return for the business. As a sole trader you and the business are the same taxpayer, so the business income and the expenses incurred in earning it are reported as a business schedule within your individual income tax return, alongside your salary, investment income and personal deductions. Preparing one means reconciling your business records, working out the net business profit, claiming the deductions you can substantiate, coordinating any GST/BAS and PAYG instalments, and lodging the whole individual return through a registered tax agent. What is deductible, and how the rules apply, depends on your circumstances — this is general information only, not personal tax advice.

Scope of work

What's included in your sole trader tax return.

Your business and your personal tax handled as one engagement — the business schedule, the deductions that stand up to scrutiny, the GST and instalment moving parts, and superannuation for the self-employed, all reconciled into a single individual return.

Business schedule within your individual return

Income · expenses · depreciation

Your business income and the expenses that relate to earning it are prepared as the business schedule inside your individual income tax return — reconciled against your bank, invoicing and any BAS already lodged, with depreciation on business assets brought in. Because a sole trader and the individual are the same taxpayer, this sits within one return rather than a separate entity lodgement.

Deductions & substantiation

Home office · motor vehicle · tools

Work-related claims reviewed properly — a home-office portion, motor vehicle running costs for business travel, tools and equipment, and other expenses incurred in earning your income. As a general matter these need to relate to the business rather than be private, and you generally need records to support them, so we test each claim against your circumstances rather than guessing.

GST / BAS & PAYG instalment coordination

Registration · activity statements · instalments

Where you are GST-registered, the BAS position is reconciled so the annual return and the activity statements tell the same story. We also coordinate any PAYG instalments — generally pre-payments of tax on business income — so they are credited correctly at year end. Whether GST registration applies, and how instalments are calculated, depends on your circumstances and the relevant rules.

Superannuation for the self-employed

Concessional contributions · timing

Sole traders generally fund their own superannuation rather than receiving employer contributions, and personal concessional contributions can, in general terms, be deductible where the contribution rules and caps are met. Whether contributing is worthwhile, and how much, depends on your circumstances and the relevant rules, so we raise it as part of the return rather than leaving it for later.

What to gather

Documents usually needed for a sole trader return.

Pulling these together before we start keeps the turnaround quick and the fixed fee tight. Most apply only if they fit your business — we confirm the list for your situation at the scoping stage.

Records checklist

  • Business bank statements for the full year
  • Invoices issued and income records, reconciled to the bank
  • Expense receipts and supplier invoices for business costs
  • A motor-vehicle logbook or business kilometres, and running-cost records
  • Work-from-home hours or floor-area records, where you work from home
  • Asset and equipment purchases, with dates and amounts, for depreciation
  • Any BAS lodged during the year, where you are GST-registered
  • PAYG instalment notices received during the year
  • Personal super contributions and any notice-of-intent paperwork
  • Your prior-year return, where you are a new client

Send through whatever you already have — we will request anything still outstanding. Business deductions generally need to relate to earning your income, with the private portion excluded, and be supported by records.

Suited to

Sole traders we prepare returns for.

ABN sole traders

Anyone running a business under their own ABN — from consultants and allied-health practitioners to online sellers and service providers. The business schedule, deductions, GST position and your individual return are prepared together so the whole picture lines up in one engagement.

Contractors & freelancers

Contractors and freelancers invoicing clients directly, often with irregular income and a mix of work and private expenses to untangle. We sort the deductible from the personal, reconcile any GST, and keep an eye on whether the personal services income rules apply to your circumstances.

BAS & GST

Tradespeople

On-the-tools operators with tools and equipment, a work vehicle, materials and travel between sites. We work through vehicle running costs, depreciation on plant and tools, and the substantiation those claims generally require so the return is defensible rather than optimistic.

Side-business & second-income earners

People earning salary alongside a growing side business — the side income, its expenses and any GST threshold question folded into the same individual return as the day job, so both income streams and the overall tax position are reflected in one place.

Worked example

How business profit flows into your individual return.

A simple illustration of how business income and expenses become net profit, which is then included in your individual return. The figures are general and for explanation only — your result depends on your facts and the rules for the income year.

Gross business income
$120,000
Less deductible business expensesSubject to substantiation, with the private portion excluded
$38,000
Net business profit
$82,000

Illustration only — figures are general and not personal tax advice.

The net business profit of $82,000 is included in your individual return and combined with any other income you have — salary, interest or dividends — to work out your total taxable income. Income tax and the Medicare levy are then calculated on that total, not on the business profit alone, so a sole trader does not pay a separate “business” rate of tax.

This is general information only and not personal tax advice. Which expenses are deductible, and how GST, PAYG instalments and any business loss are treated, depends on your circumstances and the rules for the relevant income year, which we review inside an engagement.

Process

From records to lodgement — one clear sequence.

A document-driven engagement where you always know what is next, what the fixed fee covers and when lodgement happens. We also coordinate with the rest of your accounting work — see all our accounting services.

Records & reconciliation

We gather your business records — bank data, invoicing, expense receipts and any BAS already lodged — and reconcile them so business income and expenses are settled before any deduction work begins. Clean source data is what keeps the return defensible.

Business schedule & deductions review

The business schedule is prepared and each deduction is reviewed against your circumstances and the substantiation behind it — home office, motor vehicle, tools and depreciation — then folded into your individual return alongside your other income.

Lodgement & next-year planning

The return is finalised and lodged through the tax-agent portal. We then flag the year ahead — any PAYG instalment obligations and superannuation contribution timing — so the next year is planned rather than reactive. This is general guidance, not personal advice.

Before we lodge

Sole trader risk areas before lodgement.

On sole trader returns the questions are usually about splitting private from business use and making sure income is complete. The notes below cover what we check first — general information, not advice on your situation.

Private vs business apportionment

Home office · vehicle · phone

Where an expense has both a business and a private use — a vehicle, phone, internet or part of the home — only the business portion is generally deductible, and the split needs to be reasonable and supported by records. We work out the apportionment with you rather than claiming the full amount.

Personal services income (PSI)

May affect deductions and treatment

Where income is mainly a reward for your personal skills or effort, the personal services income rules may affect which deductions are available and how the income is treated. Whether the rules apply depends on the facts, so we review your situation rather than assuming they do not.

GST registration threshold

$75,000 turnover, measured over 12 months

GST registration generally becomes compulsory once turnover reaches the $75,000 threshold, measured over a rolling twelve-month period, and some industries have their own rules. We watch your turnover trajectory so registration happens when it is required rather than after the fact.

Non-commercial business losses

May be deferred to a future year

A business loss cannot always be offset against your other income in the same year. The non-commercial loss rules may defer a loss unless the business meets one of the relevant tests, or an exception applies. We test the position rather than assuming a loss is immediately deductible.

Other areas — substantiation of cash income, depreciation on business assets and superannuation timing for the self-employed — may also need review depending on your circumstances and the rules for the relevant income year.

Frequently asked questions

Sole trader tax return — common questions.

Common questions

What can a sole trader generally claim as a deduction?

As a general guide, a sole trader can generally claim expenses that directly relate to earning their business income — things like materials, tools, software subscriptions, motor vehicle running costs for work travel, and a portion of home-running costs where part of the home is used for the business. Two conditions usually matter: the expense must relate to earning your assessable income rather than being private, and you generally need records to substantiate it. What is deductible, and to what extent, depends on your circumstances and the relevant rules, so we review each claim rather than applying a blanket assumption.

Do I need to register for GST as a sole trader?

In general terms, GST registration becomes compulsory once your business turnover reaches the $75,000 threshold (measured over a rolling twelve-month period), and is otherwise optional below that level. Some industries have their own rules, and there can be reasons to register voluntarily before reaching the threshold. Whether and when you should register depends on your circumstances and the relevant rules, so we look at your turnover trajectory and the practical effect on your pricing and cashflow as part of the engagement.

What is included in a sole trader tax return engagement?

Typically the engagement covers the business schedule within your individual income tax return — business income, the expenses and depreciation that relate to earning it — together with the rest of your individual return, so your salary, investment income and personal deductions are all reflected in one place. Where relevant we coordinate the GST/BAS position and any PAYG instalments, and we review superannuation for the self-employed. The exact scope depends on your situation, and a fixed fee covering that scope is confirmed in writing before work starts.

How do PAYG instalments work for a sole trader?

As a general matter, once a sole trader starts reporting business profit, the ATO can bring them into the PAYG instalments system — pre-paying tax on business income in quarterly (sometimes annual) instalments rather than in one lump sum after lodgement. The instalment amount is generally based on either the ATO-issued figure or a rate applied to your actual income, and it is credited against your final assessment. How the system applies to you, and which option suits your cashflow, depends on your circumstances and the relevant rules, so we walk through it rather than leaving the first notice as a surprise.

I am applying for a home loan — can you help?

Our role here is the accounting: we prepare the sole trader returns and financials that self-employed borrowers are usually asked to provide, prepared accurately and on time, which is what lenders rely on. This is not a sales pitch and the two engagements are kept separate. If a self-employed home loan also happens to be on your agenda, the same practitioner can scope that conversation separately and on its own merits — see Self-employed home loans for how that works.

How is a sole trader tax return priced?

Fees depend on the condition of your records, whether you are GST-registered, the number of income streams and whether there are vehicle, home-office or depreciation claims to work through. We quote a fixed fee in writing, scoped to your situation, after a short scoping call. There is no standard dollar figure because every sole trader differs.

Can a sole trader business loss reduce my other income?

Not always. Where deductible business expenses exceed business income there is a loss, and in some cases that loss can be offset against your other income such as salary — but the non-commercial loss rules can defer the loss to a future year unless the business meets one of the relevant tests, or an exception applies. Whether a loss can be used this year, or is carried forward, depends on your circumstances and the rules for the relevant income year, so we test the position rather than assuming the loss is immediately deductible.

Where this fits in the bigger picture

A sole trader return connects to the rest of your tax and business position — your individual return, any partnership you are part of, the BAS cycle, advisory as the business grows, and lending where it becomes relevant.
