Top Tax Deductions Every Small Business in Australia Should Know
Running a small business in Australia means juggling operations, finances, and compliance. But one of the smartest ways to boost profits is by reducing your tax liability — legally and strategically.
Understanding tax deductions can help you reclaim hundreds or even thousands of dollars each year. In this guide, TSG Accountants explains the key small business tax deductions recognised by the Australian Taxation Office (ATO) — and how professional accounting support ensures you claim every eligible expense.
What Are Tax Deductions and Why They Matter
A tax deduction is any expense directly related to earning your income. By claiming eligible business expenses, you reduce your taxable income, which means paying less tax.
However, the ATO has strict rules on what qualifies. Working with a professional through our Business Accounting service ensures your deductions are compliant, accurate, and well-documented.
Common Tax Deductions Every Small Business Should Know
Here are the top categories every business owner should review when preparing their tax return:
Vehicle and Travel Expenses
If you use your car for business — visiting clients, making deliveries, or attending meetings — you can claim deductions for:
- Fuel and maintenance
- Registration and insurance
- Depreciation or lease payments
- Parking and tolls
Keep a logbook or use the cents per kilometre method for record-keeping.

Home Office Expenses
With remote work on the rise, the ATO allows small business owners and sole traders to claim home office deductions, such as:
- Electricity, internet, and phone costs
- Office equipment (computers, printers)
- Furniture and cleaning expenses
You can claim using either the fixed rate or actual cost method — and our Individual Tax Services team can help determine which option saves you more.
Business Premises Costs
If you operate from a commercial location, you can deduct:
- Rent, water, and electricity
- Council rates and land tax (if owned)
- Repairs, cleaning, and security services
Even if you use part of your home as a workspace, you may still qualify for a partial deduction.
Depreciation of Assets
The instant asset write-off program allows eligible small businesses to claim immediate deductions for the cost of assets like computers, machinery, or office furniture.
The ATO frequently updates asset value limits, so always confirm with a Business Accounting professional before making large purchases.
Employee Wages, Superannuation & Training
If you employ staff, you can claim deductions for:
- Salaries and wages
- Superannuation contributions
- WorkCover and insurance
- Professional training and education
Encouraging development through training is not just good management — it’s also tax-smart.
Marketing & Advertising
Building awareness of your business is essential, and promotional expenses are 100% deductible, including:
- Website design and SEO services
- Online advertising (Google, Meta, LinkedIn)
- Printing, flyers, and signage
- Event sponsorships and promotions
Good marketing grows revenue — and smart accounting ensures you claim the costs properly.
Professional Fees and Business Services
Any professional advice or financial service that directly supports your business operations is tax-deductible. Examples include:
- Accounting and bookkeeping fees
- Legal and business consulting
- Tax planning and audit preparation
If you’re not sure what qualifies, consult our Business Structure experts to ensure your setup and professional costs are fully optimised.
Insurance Premiums
Business insurance costs are typically deductible, including:
- Public liability
- Professional indemnity
- Asset or equipment insurance
- Workers’ compensation
However, keep in mind that personal life insurance is not deductible under ATO guidelines.
Bad Debts
If you’ve made all reasonable efforts to recover unpaid client invoices, you may claim them as bad debts. You must write them off before the end of the financial year and keep proper records.
Our Business Accounting specialists can guide you through documenting and claiming these losses correctly.
Software and Technology Expenses
Modern businesses rely on software — and these costs are deductible too. You can claim for:
- Accounting programs like Xero or MYOB
- Cloud storage services
- Antivirus and cybersecurity tools
- Business-specific software subscriptions
Keeping software expenses organised throughout the year makes end-of-year accounting much easier.
Often Forgotten Tax Deductions
Even the most careful business owners sometimes miss out on smaller claims. Some examples include:
- Bank and merchant fees
- Subscriptions to professional associations or industry journals
- Protective clothing or uniforms
- Mobile and internet bills (business percentage)
- Postage and courier services
Our Individual Tax Services team can help ensure every eligible deduction appears on your return — no matter how small.
Record-Keeping — The Foundation of Good Tax Management
To support your claims, the ATO requires you to keep business records for at least five years. That includes invoices, bank statements, and receipts (digital or paper).
If you’re unsure how to manage these efficiently, our Sole Trader Accounting team offers tailored solutions with automated bookkeeping and cloud integration.
