Business Tax Return Guide for Sydney
A business tax return should not be the first time the year is properly understood.
By the time the return is prepared, the business has already made its sales, paid its suppliers, processed wages, lodged BAS, bought assets, taken owner drawings, used company money, borrowed funds, written off old invoices or carried problems forward from the bookkeeping file.
The return brings those pieces together.
That is why a business tax return is not only a lodgement task. It is a review point. It should show whether the business records, structure, tax position, and year-end figures can support what is being reported to the ATO.
This guide is for Sydney business owners who want to know what needs to be ready before the return is prepared, what usually slows the process, and why the structure of the business affects the work.

The Return Depends On The Structure
The first question is simple: What type of business is lodging?
The ATO’s income tax return guidance for businesses explains that the tax return process differs depending on whether the business is a sole trader, partnership, company or trust.
That structure affects how the return is prepared.
A sole trader’s business income is reported through the individual’s tax return. A partnership lodges a partnership return, and each partner’s share flows through to their own tax position. A company lodges its own company tax return. A trust return needs to address trust income, beneficiaries, distributions, and the trust’s records.
That means the same business activity can yield different returns depending on the structure used.
Before preparing the return, I want the structure to be clear because it affects:
- which return needs to be lodged
- who reports the income
- how profit or loss is allocated
- how money taken by owners is treated
- whether company loans or director payments need review
- whether trust distributions need support
- whether partnership drawings and partner balances are clear
- what financial statements are needed
A return should fit the structure. The structure should not be forced around the return.
If you are unsure whether your current structure still suits the business, the broader “Accounting Services in Sydney” page is a useful starting point.
The Year Needs To Be Closed Before The Return Is Prepared
A business tax return should not be built from half-finished records.
Before preparing the return, the year needs to be brought into order. That usually means the bookkeeping file, bank accounts, payroll records, BAS figures, asset purchases, loans and owner payments need to be reviewed.
The ATO’s record-keeping rules for business explain that businesses must keep records of transactions relating to tax, super and registrations.
For a business tax return, those records are not background paperwork. They are the evidence behind the return.
A year-end review should usually check:
- income has been recorded properly
- bank accounts have been reconciled
- supplier bills are complete
- customer invoices and payments are matched
- GST and BAS figures make sense beside the annual accounts
- payroll reports agree with the bookkeeping file
- superannuation records are clear
- loans and finance payments have been treated properly
- asset purchases have been separated from normal expenses
- private or mixed-use costs have been reviewed
- owner drawings, director payments or partner transactions are labelled clearly
If those areas are not ready, the return may be delayed or prepared from weak information.
BAS Figures Should Agree With The Annual Story
A business tax return is not separate from BAS.
If the business is registered for GST or has PAYG withholding, BAS lodgements during the year form part of the tax record. The ATO’s BAS and GST tips are useful because many year-end problems begin with GST coding, missing records or activity statement figures that were not checked carefully enough.
Before preparing the annual return, I want to know whether the BAS figures align with the year-end accounts.
Common issues include:
- GST on sales not matching income records
- supplier bills missing from the BAS periods
- payroll reports not matching PAYG withholding
- asset purchases treated incorrectly for GST
- private-use expenses claimed in full
- transfers coded as sales
- loan repayments coded as ordinary expenses
- prior BAS corrections not reflected properly
- GST credits claimed without strong invoice records
If BAS and annual accounts do not agree, the difference should be reviewed before the return is lodged.
It is much better to find that issue during preparation than after the return is submitted.
If your BAS history is already unclear, my page on the BAS accountant in Sydney explains how I review the activity statement figures behind the lodgement.
Income Needs To Be Complete, Not Just Deposited
A bank deposit is not always the full story of income.
Some businesses receive income through invoices. Others use merchant facilities, platforms, cash sales, subscriptions, delivery apps, online stores, booking systems, marketplaces, deposits, progress claims or multiple bank accounts.
The tax return needs income that reflects the business activity, not just what looks obvious in the bank feed.
A Sydney business may need to review:
- sales invoices
- POS reports
- merchant statements
- Stripe, PayPal, Square or platform payouts
- Shopify or marketplace sales reports
- cash sales
- customer deposits
- progress payments
- refunds and credit notes
- bad debts
- related-party income
- overseas or interstate income where relevant
The key question is not only “what came into the bank?”
The better question is “what did the business actually earn, and has it been recorded correctly?”
This matters because some platforms deposit net amounts after fees. If only the net deposit is recorded, income and fees may both be understated. That can distort the return and the business’s understanding of performance.
Expenses Need Evidence And Correct Treatment
A business expense should be more than a line in the bank account.
The return should be supported by records showing what the expense was, who supplied it, when it was paid and how it related to the business.
The ATO business deductions guide explains the broad principle that business expenses generally need to be directly related to earning assessable income.
At tax return time, I usually review whether expenses have been treated properly.
Some costs are ordinary business expenses. Some are assets. Some include private use. Some relate to loans. Some are capital in nature. Some need depreciation. Some may not be deductible. Some may be deductible, but only if the record is strong enough.
Areas that often need review include:
- vehicles
- tools and equipment
- software
- subscriptions
- professional fees
- insurance
- rent
- repairs and maintenance
- home office costs
- phone and internet
- interest and finance costs
- travel
- entertainment
- staff costs
- subcontractors
- stock and materials
- marketing
- training
A tax return should not claim expenses just because they were paid from the business account. The claim needs to match the business use and the evidence.
Payroll Can Delay A Business Tax Return
Payroll affects more than pay day.
It affects wages, PAYG withholding, superannuation, leave, payroll liabilities, BAS, profit reporting and the year-end return.
Before preparing the business tax return, the payroll records should be checked against the accounting file.
That may include:
- wage totals
- PAYG withholding
- superannuation
- pay runs
- payroll liabilities
- leave balances
- reimbursements
- allowances
- staff costs by period
- Single Touch Payroll records
- year-end payroll finalisation
If payroll reports do not match the profit and loss statement or the balance sheet, the return may be prepared using inconsistent records.
This is especially important for Sydney businesses that started hiring during the year, changed payroll systems, added casual staff, brought on apprentices, processed manual pay runs or had superannuation timing issues.
If payroll is part of the problem, my page on payroll services in Sydney explains how payroll records connect to bookkeeping, BAS and tax.
Assets Should Be Reviewed Separately From Ordinary Expenses
A business may buy equipment, vehicles, tools, furniture, technology, machinery, fit-out items, software systems or other assets during the year.
Those purchases should not be buried inside ordinary expenses without review.
The return may need to consider depreciation, instant asset write-off eligibility, private use, GST treatment, finance arrangements and when the asset was first used or installed ready for use.
For each significant asset, useful records include:
- purchase invoice
- payment record
- finance or lease documents
- date first used
- business-use percentage
- GST treatment
- private-use details
- registration or insurance where relevant
- disposal records if an asset was sold or traded in
The ATO’s instant asset write-off guidance should be checked before relying on the immediate deduction treatment, as timing and eligibility can change.
A business tax return should clearly show the asset position, not just claim the largest number possible.
Loans, Finance And Owner Money Need Clean Labels
Many year-end problems sit on the balance sheet.
The profit and loss report may look reasonable, while loans, director accounts, owner drawings, partner balances or unpaid amounts tell a different story.
Before preparing a business tax return, the movement of money needs to be labelled correctly.
That may include:
- business loans
- vehicle finance
- equipment finance
- credit cards
- director loans
- shareholder loans
- owner drawings
- reimbursements
- partner capital accounts
- trust beneficiary balances
- money introduced by the owner
- private expenses paid by the business
- business expenses paid personally
This is especially important for companies.
A company is separate from the director. If money has moved between the company and the director without clear treatment, the company tax return and the director’s personal tax position may both need review.
If company money has become unclear, my page on corporate tax accountant in Sydney explains how I review company tax, director payments and company records.
Sole Trader Returns Need Business And Personal Details To Meet Properly
A sole trader’s business results usually form part of the individual tax return.
That means business income and expenses need to be prepared properly, but personal tax details also matter. The final result may be affected by salary income, investment income, rental property, deductions, HELP debt, Medicare levy, private health insurance, PAYG instalments and other personal tax matters.
A sole trader’s return can become messy when business and personal spending are mixed.
Before lodgement, I usually want to see:
- business income
- business expenses
- bank records
- personal contributions to the business
- business costs paid personally
- motor vehicle records
- home office records
- GST and BAS records where relevant
- PAYG instalment history
- any other income or deductions affecting the individual return
The business result is only one part of the owner’s overall tax position.
Company Tax Returns Need Director Discipline
A company tax return requires a clean company file.
Income, expenses, BAS, GST, payroll, assets, loans, director payments, retained profits and prior-year balances all need to be reviewed.
The most common issue is the movement of funds between the company and the director.
A director may take funds from the company during the year. The tax treatment depends on what the payment actually was.
Possible treatments include:
- wages
- reimbursement
- dividend
- director loan
- repayment of money owed
- business expense
- private expense paid by the company
These are not interchangeable.
A company tax return should not be lodged while director payments are unclear. If the company has made a profit but cash is low, that also needs explanation. The answer may involve drawings, loans, BAS, payroll, supplier bills, debt repayment or asset purchases.
The return should close the company’s year properly, not leave the director guessing.
Partnership Returns Need Both Partners To Understand The Numbers
A partnership return reports the business result, but the partners also need their own shares of partnership income or loss.
That means partner records need care.
Common areas to review include:
- profit allocation
- partner drawings
- capital contributions
- expenses paid personally by partners
- reimbursements
- partnership assets
- GST and BAS
- loans
- partner balances
- information needed for each partner’s personal tax return
A partnership can create tension when one partner takes more cash than another or when the accounting does not clearly show who contributed what.
The partnership return should make the business result and partner positions easier to understand.
If the partnership records are unclear, my page on partnership accountant in Sydney explains how I review partner drawings, profit sharing and accounting records.
Trust Returns Need Distribution Records
Trust tax returns require proper records of income, expenses, beneficiaries, and distributions.
A trust return may involve business income, investment income, property income, capital gains, company beneficiaries, unpaid present entitlements, loans, trust resolutions and beneficiary tax positions.
The trust deed and distribution decisions matter.
Before preparing the return, I usually want to understand:
- what income the trust earned
- which beneficiaries are involved
- whether the trust deed has been considered
- whether distribution decisions were made properly
- whether unpaid amounts are recorded clearly
- whether a company beneficiary is involved
- whether prior-year balances make sense
- whether legal advice is needed on the deed or trustee issues
I do not treat trust distributions as a casual year-end entry. The return should reflect decisions that are supported by records.
If trust records need review, my page on family trust accountant in Sydney explains the accounting and tax issues that can sit behind a trust return.
The Return Should Explain Tax Payable Before Lodgement
A business owner should not find out what the return means only after it is lodged.
Before submission, the result should be explained.
That includes:
- whether tax is payable
- why the amount looks the way it does
- what deductions were included
- what deductions were limited or left out
- whether records affected the result
- whether PAYG instalments may follow
- whether losses or carry-forward items are involved
- whether BAS, payroll or bookkeeping issues were found
- what should be improved before next year
A tax return can reveal business patterns that were easy to miss during the year.
Maybe profit rose, but cash did not. Maybe wages increased faster than income. Maybe GST was spent before BAS. Maybe the owner’s drawings were too high. Maybe equipment purchases reduced tax but hurt cash flow. Maybe bookkeeping slowed the return down more than necessary.
That explanation is part of the value of properly preparing the return.
What To Prepare Before Speaking To Rafal
You do not need a perfect file to ask for help, but having the right information makes the first discussion more useful.
For a business tax return review, prepare what you can:
- accounting software access, such as Xero, MYOB or QuickBooks
- bank statements or reconciled bank feeds
- profit and loss report
- balance sheet
- BAS lodgements
- payroll reports
- superannuation records
- sales invoices
- supplier bills
- asset purchase invoices
- loan and finance documents
- vehicle records
- stock records where relevant
- prior-year tax returns
- trust, company or partnership documents where relevant
- ATO letters or payment plan details
- notes about anything unusual during the year
If something is missing, say so. Missing information is better identified early than hidden inside the return.
Business Tax Return Preparation Should Improve Next Year
A well-prepared return should do more than close the year.
It should show what needs improvement.
That might mean:
- better bookkeeping habits
- earlier BAS review
- cleaner payroll records
- stronger receipt capture
- more regular financial reporting
- clearer director payment treatment
- better separation of business and private spending
- earlier tax planning
- stronger cash flow forecasting
- a structure review before the business grows further
The return is at the end of one year, but it should also make the next year easier to manage.
That is the difference between lodging a return and learning from it.
Bring The Year Into One Clear Review
If your Sydney business is ready for tax return preparation, start with the year that needs to be closed properly.
Bring the structure, records, BAS history, payroll reports, bookkeeping file, asset purchases, loans and any part of the result that does not make sense.
I’m Rafal Slowinski, Director of Tax Accounting Group Pty Ltd. I can help review what is ready, what is missing and what needs to be understood before the return is lodged.

Frequently Asked Questions
Useful records include access to accounting software, bank reconciliations, BAS lodgements, payroll reports, superannuation records, sales invoices, supplier bills, asset invoices, loan documents, vehicle records, and prior-year returns. The exact records depend on the business structure.
No. BAS is used during the year to report obligations such as GST and PAYG. A business tax return reports the annual income tax position. BAS figures should still be reviewed against the year-end accounts before the tax return is lodged.
Yes, but the bookkeeping may need to be reviewed or cleaned up first. A return should not be rushed from unreliable records. Rafal can identify what is missing and what needs correction before preparation continues.
No. Each structure has different reporting requirements. Companies, trusts, partnerships, and sole traders need tax returns prepared to reflect their structure correctly.
Yes, especially if tax planning, asset purchases, payroll, BAS, director payments, trust distributions or cash flow are likely to affect the result. Some decisions are more useful before the year closes.
