Business Tax Return Guide for Australian Small Businesses

Know what to prepare, what you can claim, and what the deadlines are - so your tax return gets done right, every year.

Tax time catches a lot of small business owners off guard - not because the process is complicated, but because nobody told them what to keep track of during the year. Our tax return service handles the lodgement for you, but this guide will help you understand what is involved, what you need to provide, and what you might be missing.

Know Your Obligations

Tax Returns by Business Structure

Your lodgement obligations depend on how your business is structured. Here is a quick overview of each.

Sole Trader

Individual Tax Return

As a sole trader, your business income is reported in your personal individual tax return. There is no separate business return. You report your business income and claim your business deductions in the business schedule attached to your individual return. Your tax is calculated at individual income tax rates.

Company

Company Tax Return

A company is a separate legal entity and lodges its own company tax return. The company pays tax on its net profit at the corporate tax rate - currently 25% for base rate entities (most small businesses). Directors may also need to lodge individual returns for any salary or dividends received.

Partnership

Partnership Return and Individual Returns

A partnership lodges a partnership tax return to report the partnership's income and expenses, but the partnership itself does not pay tax. Each partner then includes their share of the net income in their own individual tax return and pays tax at their personal rate. Both the partnership return and each partner's individual return need to be lodged.

Trust

Trust Return and Beneficiary Returns

A trust lodges a trust tax return each year. The trust generally does not pay tax itself - instead, the net income is distributed to beneficiaries, who each include their distribution in their own individual or company tax return. Both the trust return and each beneficiary's return need to be lodged. Trust tax obligations can be complex, so contact us to discuss your specific situation.

Note: AffordBooksTax lodges tax returns for all four structures. Pricing for companies, partnerships and trusts is based on your annual business revenue. Sole trader returns are priced separately — see personal tax returns. See our full pricing for details.

Deadlines

Tax Return Lodgement Deadlines

Missing a deadline can mean penalties and interest. Know your dates before the end of financial year.

Self-lodged
31 October
Deadline for individuals and sole traders who lodge their own return. Applies to returns for the year ended 30 June.
Via registered tax agent
Extended deadline
When AffordBooksTax lodges as your registered tax agent, you are typically eligible for an extended lodgement deadline well beyond 31 October. Ask us when you come on board.
Companies and trusts
28 February
Most company and trust returns are due 28 February following the end of the financial year, when lodged through a tax agent.
Turnaround time
1 to 2 weeks
Once we have everything we need from you, we aim to have your return ready for review within 1 to 2 weeks.
Important: Even if you cannot pay the tax owing, you should still lodge on time. The Failure to Lodge penalty applies separately from any tax debt and compounds the longer you wait.

What to Prepare

What You Need to Provide for Your Tax Return

Click each section to expand. The more complete your information, the faster we can turn it around.

1
Personal information

This is the foundation of your return. Make sure all of these are current and correct before we start.

  • Full name, date of birth and current residential address
  • Tax File Number (TFN)
  • Bank account details for any refund
  • Private health insurance details - policy number and annual statement
  • Spouse details if applicable - name, date of birth, income and private health cover status
  • Dependant details if applicable - names, dates of birth and any income they earned
2
Income Most important

All income needs to be declared, regardless of how it was received or which bank account it went into. This is one of the most common areas where things get missed.

  • PAYG payment summaries or income statements from employers
  • Government payments - Centrelink, JobSeeker, Age Pension, parental leave
  • Superannuation income streams and lump sum payments
  • Interest income from bank accounts
  • Dividend statements including franking credits
  • Managed fund annual tax statements
  • Rental property income - annual statement and lease agreements
  • Capital gains from property, shares, crypto or other assets sold during the year
  • Foreign income from employment, investments or pensions
  • Business or contractor income - ABN invoices and bank statements
  • Any other income including tips, scholarships or jury duty payments
3
Deductions Most missed

Deductions reduce your taxable income, so missing them costs you money. The most common issue we see is business owners who paid for work expenses through their personal bank account and never kept a record of it. If you spent money for your business, it may be deductible - even if it came from a personal account.

  • Work-related expenses - tools, uniforms, protective clothing, training courses
  • Vehicle and travel expenses - logbook records, kilometres travelled, public transport for work
  • Home office expenses - electricity, internet, phone, office equipment
  • Work from home hours - total hours worked from home
  • Self-education expenses - course fees, textbooks, stationery related to your current work
  • Union fees and professional memberships
  • Last year's tax agent fees
  • Donations to registered charities with receipts
  • Income protection insurance premiums
  • Personal superannuation contributions with a valid notice of intent to claim
  • Other deductions - subscriptions, industry journals, seminars
4
Rental property If applicable

If you own a rental property, there are specific documents your accountant needs to claim all available deductions and report the income correctly.

  • Annual rental statement from your property manager
  • Council rates, water rates and strata levies
  • Interest on investment loans - loan statements for the year
  • Repairs, maintenance and any capital improvements made during the year
  • Insurance premiums - landlord, building and contents
  • Depreciation schedule if you have one
5
Offsets and rebates If applicable

Offsets directly reduce the amount of tax you pay, not just your taxable income. They are worth checking every year.

  • Private health insurance rebate details
  • Superannuation spouse contribution details
  • Zone or overseas forces offsets if applicable
  • Low income and senior tax offset eligibility
  • Family tax benefit and childcare rebates
6
Other documents

These are less common but important if they apply to you. If the ATO has been in contact with you during the year, that correspondence is always relevant.

  • Any ATO correspondence received during the year - notices, statements, letters
  • HECS or HELP debt statements
  • Medicare levy exemption certificates if applicable

Watch Out For

What Small Business Owners Commonly Miss

These come up regularly. Being aware of them before you gather your documents can save you money.

Expenses through personal accounts

The most common issue we see. If you paid for a business expense from your personal bank account or personal credit card, it is still potentially deductible. Keep receipts and note what each expense was for, even if it did not go through your business account.

Not keeping a vehicle logbook

If you use your car for work, a logbook is the most accurate way to calculate your deduction. Without one, you are limited to the cents per kilometre method, which caps at 5,000 kilometres per year. A properly maintained logbook almost always results in a larger deduction.

Forgetting last year's tax agent fees

The fees you paid AffordBooksTax last year to prepare your tax return are deductible this year. It is a small item but often forgotten. Dig out last year's invoice and include it.

Missing capital gains events

Selling shares, property or crypto during the year triggers a capital gains event that must be reported. Even if you made a loss, it needs to be declared because capital losses can be used to offset future gains. Crypto is an area where many people assume it does not need to be reported - it does.

Not claiming home office correctly

Since 2024 the fixed rate method for home office claims changed to 70 cents per hour. You need to keep a record of actual hours worked from home, not just an estimate. A simple log or diary entry is enough, but you need to have it.

Waiting until July to get organised

The financial year ends 30 June. If you wait until July to start gathering documents, some records will be harder to find and some deductions may not be claimable because the evidence is missing. Start a folder in June and drop documents in as they arrive.

FAQ

Frequently Asked Questions

What is the tax return deadline for small businesses?
If you lodge your own return, the deadline is 31 October for individuals and sole traders. If a registered tax agent lodges on your behalf, you are typically eligible for an extended deadline. Companies and trusts lodged through a tax agent are generally due 28 February. Contact us early in the financial year to lock in your extended deadline.
Do I need to lodge a tax return if my business made a loss?
Yes. Even if your business made a loss, you are still required to lodge a return. Declaring a loss is also important because it may be carried forward to offset income in future years, which can reduce your tax in a profitable year down the track.
How long does it take to get my tax return done?
Once we have all the documents and information we need from you, we aim to have your return ready for review within 1 to 2 weeks. The most common cause of delays is incomplete information from the client, which is why we send a checklist at the start of the process.
Can I claim expenses I paid from my personal bank account?
Yes, you can. The ATO does not require business expenses to be paid from a dedicated business account. What matters is that the expense was genuinely for your business and you have evidence of it -- a receipt, invoice or bank statement showing the transaction. This is one of the most commonly missed deduction opportunities for small business owners.
What is the difference between a tax return and financial statements?
A tax return is the document lodged with the ATO to report your income and calculate your tax liability. Financial statements (profit and loss statement and balance sheet) are a summary of your business finances for the year. They are used for business decisions, loan applications and are required for some business structures. They are separate services billed separately. See our pricing page for both.
Do I need to lodge a tax return for my company even if it had no activity?
Yes. A registered company is required to lodge a company tax return every year regardless of whether it traded or made any income. Failing to lodge attracts a Failure to Lodge penalty from the ATO. If your company is dormant and you want to close it, get in touch and we can help you understand the deregistration process.
