Australian Tax Deductions Most People Miss

Thousands of Australians miss out on tax deductions every year. In 2025, new rules and digital record-keeping make it easier to claim—but only if you know what’s eligible.

Claiming overlooked deductions can increase your refund or reduce your tax bill.

Common deductions Australians miss

• Work-from-home expenses: Internet, phone, electricity (ATO fixed rate or actual costs).
• Professional subscriptions: Industry association fees, trade publications.
• Union fees: Annual union dues are deductible.
• Education and training: Courses directly related to your current job.
• Tools and equipment: Small tools under $300 can be claimed immediately.
• Protective clothing: Hi-vis, safety boots, sun protection for outdoor workers.
• Charitable donations: Must be to registered charities and over $2.

Home office expenses are one of the biggest missed deductions.

Keeping proper records

The ATO requires receipts or evidence for claims. Digital banking and apps make this easier than ever. Use your phone to snap receipts and keep them in a cloud folder.

Tip: Keep a mileage log for work-related car trips. Apps can track automatically.

What’s new in 2025?

• ATO fixed-rate for home office expenses updated to 70c/hour.
• Digital record-keeping apps are officially recognised.
• Threshold for immediate write-off of small assets remains at $300.

Accountants can help identify deductions you might miss on your own.

What not to claim

• Commuting costs to your regular workplace.
• Childcare expenses (not deductible).
• Entertainment or meals (unless part of travel for work).

Warning: Over-claiming can trigger an ATO audit. Always stay within the rules.
