Tax Deductions for Small Businesses in Australia: Maximise Your Claims in 2026

Tax deductions for small businesses in Australia are expenses you can claim when they are directly connected to earning business income. In 2026, maximising your claims means knowing which operating costs, assets, home office expenses, vehicle costs, digital tools, and other eligible expenses can reduce taxable income while staying within ATO rules.

As tax season approaches, accurate records become just as important as the deduction itself. This blog explains the key deductions small businesses may be able to claim, the records they should keep, and the practical steps they can use to simplify compliance, avoid missed claims, and prepare more confidently for tax time.

Key Tax Deduction for Small Businesses in Australia 2026

Certain tax deductions for small businesses in Australia are available for different expenses, including operating costs, capital expenditures and depreciation, special deductions, and incentives. Below is a breakdown of these categories to help make your tax season smoother and more efficient:

Claiming Ordinary Business Operating Expenses

Ordinary business operating expenses are day-to-day costs a business incurs to earn income. These may include rent, utilities, wages, software subscriptions, marketing, insurance, office supplies, professional fees, and other regular business costs.

To claim these deductions, the expense must be directly related to the business, properly recorded, and supported by invoices or receipts. Here are the operating expenses, in which deductions can be made:

• Premises: Rent for a business office, security, cleaning, utilities, and rates can be deducted so long as they’re not private or personal.
• Staff costs: Wages, salaries, and super payments (as long as paid by the deadlines) are deductible in full, provided they are paid by the deadlines. The Super Guarantee rate for 2025–26 is 12% of ordinary time earnings. To be deductible, super must be received by the fund before 30 June 2026, not just paid, so allow at least two weeks for processing.
• Insurance: Public liability, professional indemnity, and similar insurance types are fully deductible if they’re directly related to business activities.
• Professional services: Accountancy and legal costs connected to business affairs (not private or capital structure changes) qualify for an immediate deduction.
• Advertising, software, and IT: Marketing costs, software subscriptions, web hosting, and related digital services dedicated to earning income are valid deductions.
• Travel and vehicle: Flights, accommodation, meals, and car expenses count where records are kept and the trips are business-related not private trips.
• Repairs and maintenance: Upkeep and repairs for business assets are deductible but building improvements or upgrades need to be claimed as capital expenses over time.
• Finance costs: Interest paid on business-related loans, bank fees, and merchant charges are deductible, but any interest attached to private portions or denied assets is not. Note that General Interest Charge (GIC) or Shortfall Interest Charge (SIC) incurred on or after 1 July 2025 can no longer be claimed as an income tax deduction in 2025–26 or later tax returns. .

Capital Deductions and Depreciation

Capital deductions and depreciation help small businesses claim the cost of assets used to earn income. Unlike everyday expenses, assets such as equipment, vehicles, furniture, and fittings are usually claimed over time unless immediate write-off rules apply.

The right treatment depends on the asset’s cost, use, and ATO rules for the income year. Below are the key capital deductions small businesses should understand before claiming asset-related costs.

• Instant Asset Write-Off: For small businesses with aggregated annual turnover under $10 million, assets costing less than $20,000 each can be written off immediately, provided the asset was first used or installed ready for use between 1 July 2025 and 30 June 2026. Multiple assets can be claimed with no cap on the number of assets, the entire purchase price is deducted straight away, not spread out over several years. As of the 2026–27 Budget, the $20,000 instant asset write-off is proposed to become a permanent feature of the tax system, rather than being extended year by year.
• Simplified Depreciation: Small businesses can bundle most assets into a general pool and claim depreciation at a faster rate of 15% in the first year and 30% in subsequent years. It keeps things simple, just pool and depreciate using the standard rules .
• Uniform Capital Allowance (UCA): Medium and large businesses (or those opting out of simplified rules) must depreciate assets over their effective life, claiming a fraction of the cost each year. Not everything can be written off instantly.

Special Deductions and Incentives

Special deductions and incentives allow small businesses to claim extra benefits for eligible spending on areas such as innovation, staff training, technology, and sustainability. These deductions go beyond standard operating costs and can help reduce taxable income when the business meets ATO eligibility rules.

Because some incentives change between financial years, businesses should check current requirements before claiming. Below are the key special deductions and incentives small businesses should understand before tax time.

• R&D Tax Incentive: Companies investing in eligible research and development can benefit with a reduced tax bill (sometimes refundable, sometimes just a reduced liability), so long as the expenses fit the ATO’s criteria for R&D.
• Technology Investment and Skills & Training Boosts: These provided extra 20% deductions on digital business or employee training expenses (within eligible periods). Both boosts are now closed and no longer available for new claims in 2025–26. However, they remain relevant for businesses reviewing or amending returns for the eligible periods.
• Capital Gains Tax (CGT) Concessions: Small business entities disposing of active assets can access discounts, including a 15-year exemption, 50% asset reduction, and a retirement exemption (up to $500,000), as well as the option to roll over a capital gain into new assets.

Other Key Deductions

After covering the main claim categories, it’s important to take a look at the extra deductions and technical rules that might slip under the radar. Old debts, super payments, prepaid costs, and home office claims each come with their own rules, but can all contribute to reducing your company’s tax. Ticking these items off the list can round out a thorough and effective tax strategy.

• Bad debts: Provided the income from the debt was included in a previous year’s tax return, companies can write off bad debts and claim them as a deduction so long as they’re genuinely irrecoverable and properly documented.
• Superannuation contributions: Super paid for staff is deductible if paid on time and to a complying fund. The concessional contributions cap for 2025–26 is $30,000 per year. Sole traders can also make personal super contributions and claim a deduction, a useful strategy to reduce taxable income while building retirement savings. Penalties and interest for late super are not claimable.
• Prepaid expenses: Items like insurance or subscriptions that cover 12 months or less, and end in the following financial year, may be deducted straight away.
• Home office use: If a business runs from home, a portion of electricity, phone, and internet can be claimed using the ATO’s fixed rate of 70 cents per hour. For occupancy expenses (like rent or the mortgage interest), these are only claimable if the home is used exclusively, or almost exclusively, as a place of business, taking care, as this could affect CGT if the property is sold.

Making Compliance Easy: Best Practices

ATO audits are not that stressful when a company’s records are in order. Here are a few tips:

• Use cloud accounting or digital filing systems to sort, store, and back up documents.
• Review expenses regularly, so nothing is missed or claimed in error.
• Separate personal expenses from business accounts to avoid complications.
• Work with a registered tax agent or accountant, especially for tricky areas like asset write-offs, CGT, and specific incentives.
