What Tax Deductions Can a Small Business Claim in Australia?

Understanding what expenses your small business can legitimately claim as tax deductions is one of the most practical ways to manage your tax position. Many business owners miss legitimate deductions because they're unsure what's claimable, while others claim things they shouldn't — creating compliance risk.

This article covers common business deductions for Australian small businesses. Tax treatment can depend on your circumstances and current ATO requirements, so this information is general in nature. For advice specific to your business, business tax return services in Burleigh Heads can help ensure you're claiming correctly.

How Tax Deductions Work

A tax deduction reduces your taxable income — not your tax bill directly. If your business earns $100,000 and has $30,000 in legitimate deductions, your taxable income is $70,000. The tax you pay is calculated on the lower figure.

The key rule is that an expense must be directly related to earning your business income to be deductible. Private expenses, capital expenses (with some exceptions), and expenses not supported by records generally can't be claimed.

Office Expenses

Day-to-day office costs are generally deductible if they're used for business purposes. This includes:

• Stationery, printing, and office supplies
• Phone and internet (the business-use portion)
• Office rent (if you rent a commercial space)
• Cleaning and maintenance of a dedicated office

Motor Vehicle Expenses

If you use a vehicle for business purposes, you may be able to claim the business-use portion of running costs. There are two main methods:

Cents Per Kilometre

A set rate per business kilometre, up to a maximum of 5,000 km per vehicle per year. This covers all running costs — fuel, registration, insurance, servicing, and depreciation. No receipts are needed for the expenses, but you need to be able to show how you calculated the business kilometres.

Logbook Method

You keep a logbook for 12 weeks to establish the business-use percentage, then claim that percentage of all actual vehicle expenses. This method usually results in a larger deduction for vehicles with high business use. For more detail, see our article on vehicle tax deductions for tradies.

Tools and Equipment

Tools, equipment, and machinery used for business purposes are deductible, but how they're claimed depends on cost and useful life. Lower-cost items may be claimed immediately under small business concessions, while more expensive assets are depreciated over their effective life.

Eligibility for immediate deduction depends on current ATO rules and thresholds, which can change. Always check the current position or speak with an accountant before claiming.

Professional Fees

Fees paid for professional services related to your business are generally deductible:

• Accounting and bookkeeping fees
• Legal fees for business matters (not capital-related)
• Business consulting and advisory fees
• Professional memberships and subscriptions

Insurance

Insurance premiums for business-related cover are deductible. This includes public liability, professional indemnity, business interruption, and workers' compensation. Personal insurance (like life or income protection taken out personally) is treated differently — seek advice on your specific situation.

Advertising and Marketing

Costs of promoting your business are deductible, including:

• Website development and hosting
• Online and print advertising
• Social media marketing
• Business signage

Software and Subscriptions

Software used for business — accounting software, CRM systems, project management tools, design software — is deductible. If the software is used partly for private purposes, only the business-use portion is claimable.

Work-Related Travel

Travel directly related to earning your business income is deductible. This includes travel to meet clients, attend business meetings, or visit suppliers. Overnight travel may include accommodation and meals, but the rules are specific — keep detailed records and be clear about the business purpose.

Travel between home and your regular place of business is generally not deductible (it's considered private). Travel between different work sites usually is.

Home-Based Business Expenses

If you run your business from home, you may be able to claim a portion of household running costs. The ATO has specific methods for calculating home-based business deductions, depending on whether you have a dedicated home office or use a shared space.

Common claimable expenses include:

• A portion of electricity and gas (based on floor area or usage)
• Phone and internet (business-use portion)
• Cleaning of a dedicated office space
• Depreciation of office furniture and equipment

The rules are detailed and the method you use affects what you can claim. For more on this, see our article on how to prepare your small business for tax time.

Depreciating Assets

Assets with a useful life longer than one year — computers, vehicles, machinery — are generally depreciated rather than claimed in full. Small businesses may be eligible for concessions that allow immediate deduction for certain assets, but the thresholds and eligibility rules change over time.

Always check the current ATO position before claiming asset purchases, or work with an accountant who can advise based on your circumstances and the current rules.

Record Keeping: The Foundation of Legitimate Claims

Every deduction needs supporting records. The ATO requires you to keep receipts, invoices, and other documents for at least five years. Without records, a claim can be disallowed — even if the expense was genuinely business-related.

For Burleigh Heads businesses, keeping good records throughout the year makes tax time far less stressful. Accounting services in Burleigh Heads can help you set up systems that make record-keeping straightforward and ensure you're claiming everything you're entitled to.
