Claiming Work-Related Tax Deductions

When the End of Financial Year (EOFY) approaches in Australia, many employees start scrambling to find receipts and figure out how to maximise their tax refund. Understanding how to properly claim work-related tax deductions is an effective way to ensure you are taking home the right amount of your hard-earned pay. Navigating the rules set out by the Australian Taxation Office (ATO) can sometimes feel overwhelming, but with a solid grasp of the basics, you can confidently manage your deductions and potentially increase your net pay. This guide provides a practical overview of what you can claim, what you cannot claim, and the critical importance of keeping accurate records throughout the year.

Understanding Work-Related Deductions and Your Taxable Income

To make sense of work-related deductions, it is essential to first understand how income tax is collected in Australia. Your employer uses a system called Pay As You Go (PAYG) withholding. Under this system, employers deduct income tax on a sliding scale from each of your paychecks and send it directly to the ATO on your behalf. This means that over the course of the financial year, you are incrementally paying your expected tax bill.

For most resident taxpayers, the first $18,200 of income earned in a financial year is generally tax-free. This is known as the tax-free threshold. Provided you actively claim the tax-free threshold with your employer by completing a Tax file number declaration when you start a job, no tax should be withheld until your earnings exceed this pro-rata amount.

When you lodge your tax return at EOFY, the ATO calculates your actual tax liability based on your taxable income. This is where deductions come into play. Work-related deductions reduce your total taxable income. By lowering your taxable income, you effectively lower the overall income tax you are required to pay for the year. If the PAYG tax withheld by your employer throughout the year turns out to be more than this final calculated tax liability, you generally receive the difference as a tax refund.

What You Can and Cannot Claim

The ATO's golden rule for deductions is that the expense must directly relate to earning your income. Employees can claim tax deductions for a variety of work-specific expenses, provided they meet this crucial criterion. Common examples of legitimate claims include the cost of buying and repairing tools of the trade, specific equipment required for your role, and home office running costs if you are required to work from home.

However, it is equally important to understand what the ATO explicitly prohibits. You cannot claim expenses for items that do not have a specific occupational focus. An area of common confusion involves clothing. General everyday clothing—even if your employer requires you to wear a specific colour or style, such as a plain black suit or standard office attire—is not deductible. Deductions are typically restricted to distinctive uniforms, occupation-specific clothing, or protective gear.

Similarly, the cost of standard commuting between your home and your regular place of work is generally considered a private expense and cannot be claimed. There are very limited exceptions to this rule, such as when you are required to carry bulky tools that cannot be securely stored at work, but for the vast majority of employees, the daily commute is strictly off-limits for tax deductions.

Substantiation, the New Standard Deduction, and Keeping Reliable Records

The substantiation rules changed in 2026, and the change simplifies things for most employees. The long-standing exception that relieved small totals of work-related claims from the written-evidence requirement was repealed, and in its place the law now provides a standard deduction for work-related expenses. If you are an Australian resident earning salary or wages, this standard deduction tops your work-related claims up to a fixed ceiling without receipts being required for the topped-up portion. A few deductions — notably union or professional-association membership fees and income-protection insurance premiums — sit outside the top-up calculation entirely, so they remain claimable in full alongside it.

If your actual work-related expenses exceed that ceiling and you claim them individually, the written-evidence rules apply in full. You need a paper or digital trail proving you incurred each expense, what it was for, the date of purchase, and the supplier's name. You must also have actually spent the money yourself and not have been reimbursed — the standard deduction changes what needs receipts, not the basic requirement that a claimed expense be real and work-related.

For itemised claims, the requirement for written evidence is strict. The ATO recommends taking photos of your receipts or using a digital record-keeping app, as thermal paper receipts can fade over time. Maintaining a well-organised folder or digital archive throughout the year can save you from a stressful scramble during EOFY.

Practical Tips for the End of Financial Year

As the End of Financial Year draws near, taking a proactive approach to your work-related deductions can pay off. Start by reviewing your bank statements and credit card history to identify any work-related purchases you might have forgotten to log. Ensure you have the corresponding receipts safely stored.

If you are claiming home office expenses, make sure you understand the current methods allowed by the ATO for calculating running costs, as these can change from year to year. Keeping a logbook or a diary of your working from home hours for a representative period might be necessary depending on the method you choose to apply.

While this guide covers the general principles of work-related deductions, tax laws can be complex and individual circumstances vary wildly. It is often a wise move to consult with a registered tax agent. A professional can provide personalised advice, ensure you are claiming everything you are legally entitled to, and help you avoid the pitfalls of over-claiming, which can lead to penalties from the ATO. By staying organised, understanding the basic rules, and seeking help when needed, you can make the most of your tax return and maximise your net pay.
