Business tax deductions are legal and eligible expenses that a business can subtract from its assessable income. These deductions help reduce the amount of income that is subject to taxation, ultimately lowering the business’s overall tax liability. Deductions are crucial for businesses to optimise their tax planning and minimise their end-of-year tax bill.

Common Business Tax Deductions

Ordinary Business Expenses

Deductible expenses are those directly related to earning assessable income. This includes rent, utilities, office supplies, and employee wages.

Commercial Vehicle Expenses

You can claim deductions for business-related car expenses. This includes fuel, maintenance, and depreciation. Keep a logbook to track the percentage of business use.

Home-Based Business Expenses

If you operate your business from home, you may be eligible to claim a portion of home-related expenses, such as rent, mortgage interest, utilities, and insurance.

Depreciation of Assets

Capital assets, like machinery or office equipment, can be claimed as a deduction over time through depreciation. The Australian Taxation Office (ATO) provides guidelines on how to calculate depreciation.

Travel Expenses

You may claim travel expenses incurred for business purposes, including accommodation, meals, and transportation. Keep detailed records, and note that personal components of travel aren't deductible.

Work-Related Education Expenses

Costs associated with courses or training directly related to your business may be deductible. Ensure the education is relevant to your current business activities.

Bad Debts

If you've declared income but haven't received payment, and it's unlikely you will, you may be able to claim a deduction for bad debts.

Professional Fees

Money spent on professional advice, such as accounting or legal fees, is generally deductible. This includes fees paid for tax advice.

Superannuation Contributions

Contributions made to your employees' superannuation funds are generally tax-deductible. Ensure you meet the Superannuation Guarantee requirements.

Insurance Premiums

Premiums paid for business insurance, such as public liability insurance, may be deductible.


Donations made to deductible gift recipients (DGRs) are generally tax-deductible. Check the ATO's list of approved DGRs.

Repairs and Maintenance

Costs associated with repairing and maintaining business property or equipment are typically deductible. However, improvements and renovations may not be immediately deductible but may be depreciable over time.

Fringe Benefits Tax (FBT) Expenses

If you provide fringe benefits to employees, the expenses associated with these benefits may be deductible.

Common Tax Deduction Mistakes

Australia’s taxation laws are notoriously complex. Here are some common mistakes that Australian business owners might make when claiming tax deductions:

Inadequate Record Keeping

Failing to keep accurate and complete records of all business expenses can lead to missed deductions. Proper documentation is crucial for substantiating claims.

Personal Expenses vs Business Expenses

Claiming personal expenses as business expenses is a common mistake. It’s important to distinguish between personal and business-related expenditure to ensure that only eligible expenses are claimed.

Incorrectly Categorising Expenses

Misclassifying expenses may result in errors and missed opportunities for deductions. Business owners should be aware of the specific categories and criteria for various deductions.

Not Claiming all Eligible Deductions

Some business owners may be unaware of certain deductions they are entitled to claim. Staying informed about the latest tax laws and seeking support from a professional can help ensure that you’re leveraging all eligible deductions.

Overlooking Depreciation

Failing to account for depreciation of business assets can lead to missed deductions. Businesses should be aware of the depreciation rules and claim depreciation on eligible assets over their useful life.

Ignoring Superannuation Obligations

Business owners need to ensure they meet their superannuation obligations for employees. Contributions to employee superannuation funds are generally tax-deductible, and failure to make these contributions on time can result in penalties.

Ignoring Small Business Concessions

Australian tax laws often provide concessions for small businesses. Ignoring these concessions or being unaware of eligibility criteria may result in missed opportunities for tax savings.

It’s important for business owners to stay informed about tax laws, keep detailed records, and seek professional support to ensure compliance and maximise eligible deductions. Tax regulations can change, so staying up-to-date is crucial for making accurate claims.
