Tax time in Australia is more than just a yearly obligation—it’s a chance to reduce your taxable income and potentially increase your refund. The key to making the most of this opportunity is understanding write-offs: the expenses you can claim to lower the amount of tax you pay. As we move into the 2026 financial year, knowing what you can claim and how to do it correctly is more important than ever.
Whether you’re a business owner, a sole trader, or an employee with work-related expenses, being across the latest rules and strategies can help you maximise your tax savings. This guide explains what write-offs are, outlines the most relevant changes for 2026, and offers practical tips to help you claim with confidence.
What Is a Write-Off?
A write-off, or tax deduction, is an expense you can claim to reduce your taxable income. The lower your taxable income, the less tax you pay. Write-offs are available to individuals, sole traders, and businesses, but the rules around what you can claim and how you claim it can differ depending on your situation.
Common Examples of Write-Offs
- Work-related expenses (such as tools, uniforms, or travel)
- Home office costs (including internet, electricity, and equipment)
- Depreciating assets (like laptops or vehicles)
- Interest on business loans
- Charitable donations
Not every expense is eligible, and the rules can change from year to year. That’s why it’s important to stay up to date and keep good records.
What’s New for 2026? Key Write-Off Changes
The 2026 financial year brings several updates that affect what you can write off, especially for small businesses, sole traders, and those working from home. Here are some of the most notable changes:
Instant Asset Write-Off
For the 2026 financial year, eligible businesses with an aggregated turnover below a certain threshold can immediately deduct the cost of assets up to a set limit if they are first used or installed ready for use between 1 July 2024 and 30 June 2026. This can be a significant benefit for businesses planning to invest in equipment or technology. Make sure to check the current threshold and eligibility criteria before making large purchases.
Depreciation Rules
The temporary full expensing measure, which previously allowed businesses to immediately deduct the full cost of eligible depreciating assets, ended on 30 June 2024. From 1 July 2024, most assets will need to be depreciated over their effective life according to standard schedules. This means you may need to spread deductions for larger purchases over several years rather than claiming the full amount upfront.
Home Office Deductions
With remote and hybrid work now common, the Australian Taxation Office (ATO) has updated the fixed rate method for claiming home office expenses. The fixed rate covers energy, internet, phone, and stationery, but you must keep detailed records of your hours worked from home. You can also choose to claim actual costs, but not both for the same expenses. Keeping accurate logs and receipts is essential.
Electric Vehicles and Fringe Benefits
The Fringe Benefits Tax (FBT) exemption for eligible electric vehicles continues in 2026, but there are stricter reporting requirements. If your business provides electric vehicles to employees, ensure you understand the current rules and maintain the necessary documentation.
Strategies to Maximise Your Write-Offs
Getting the most from your write-offs requires planning and attention to detail. Here are some practical steps to help you maximise your deductions in 2026:
1. Keep Detailed Records
Good record-keeping is essential. Store digital copies of receipts, invoices, and bank statements. Consider using accounting software to track expenses throughout the year. This makes it easier to substantiate your claims if the ATO asks for evidence.
2. Don’t Overlook Small Expenses
Small, regular expenses such as office supplies, work-related phone calls, or mileage can add up over the year. Claiming every eligible expense, no matter how minor, can make a noticeable difference to your tax outcome.
3. Time Asset Purchases Carefully
If you’re planning to buy equipment or other assets for your business, check whether the purchase qualifies for the instant asset write-off. Making the purchase before the end of the financial year could allow you to claim the deduction sooner.
4. Maximise Home Office Claims
If you work from home, keep a log of your hours and expenses. The fixed rate method can simplify your claim, but you must have records to back it up. If your actual costs are higher, consider whether claiming actual expenses is worthwhile, but remember you can’t claim both methods for the same costs.
5. Seek Professional Advice for Complex Claims
Some deductions, such as those for vehicles or investment properties, can be complex. If you’re unsure about what you can claim or how to apportion expenses between business and personal use, consider seeking professional advice. This can help you avoid mistakes and ensure you’re claiming everything you’re entitled to.
Common Pitfalls to Avoid
While write-offs can reduce your tax bill, mistakes can lead to missed opportunities or even penalties. Here are some traps to watch out for:
Poor Record-Keeping
If you can’t provide evidence for your claims, you may not be able to claim the deduction. The ATO regularly reviews claims and may request receipts or logs, especially for larger or unusual deductions.
Mixing Personal and Business Expenses
Only the business or work-related portion of an expense is deductible. For example, if you use your phone for both work and personal calls, you can only claim the work-related percentage. Keep clear records to support your calculations.
Claiming Ineligible Expenses
Not all expenses are deductible. Private expenses, or costs not directly related to earning your income, generally can’t be claimed. Stay up to date with the latest ATO guidance to avoid claiming items that aren’t allowed.
Making the Most of Write-Offs in 2026
Write-offs remain one of the most effective ways to reduce your tax bill in Australia. With new rules and thresholds in place for 2026, it’s important to stay informed and keep thorough records. By tracking your expenses, understanding what you can claim, and seeking advice when needed, you can make the most of your tax return this year.
Remember, tax laws and thresholds can change, so always check the latest information or consult a professional if you’re unsure. Taking a proactive approach now can help you avoid surprises at tax time and ensure you’re making the most of every opportunity to save.
