Understand What Expenses You Can Claim

Many Australians miss out on deductions because they don’t know what expenses are eligible. Common deductible expenses include:

• Work-related expenses such as uniforms, tools, and travel costs (excluding commuting).

• Home office expenses if you work from home, including a portion of electricity, internet, and phone bills.

• Self-education costs related to your current job.

• Donations to registered charities.

• Investment expenses like interest on loans for investment properties or shares.

  
  

Keep detailed records and receipts for all these expenses. The Australian Taxation Office (ATO) requires proof to support your claims.

Use the Instant Asset Write-Off for Small Business Owners

If you run a small business or are self-employed, the instant asset write-off allows you to immediately deduct the cost of eligible assets purchased for your business. In 2026, the threshold remains generous, so you can claim items like computers, tools, or office furniture without depreciating them over several years.

For example, if you buy a laptop for $1,500 used exclusively for your business, you can claim the full amount in the same financial year. This reduces your taxable income and improves cash flow.

Claim Work-From-Home Expenses Correctly

With many Australians continuing to work remotely, claiming home office expenses is more relevant than ever. The ATO offers two methods:

• Fixed rate method: Claim 67 cents per hour for running expenses like electricity and depreciation of office furniture.

• Actual cost method: Calculate the exact expenses based on your bills and usage.

  
  

Choose the method that gives you the highest deduction, but keep accurate records such as timesheets and bills. For example, if you worked 1,000 hours from home, the fixed rate method would allow a $670 deduction.

Review Your Investment Income and Expenses

If you have investments, review all related income and expenses carefully. You can claim deductions for:

• Interest on loans used to buy shares or investment properties.

• Management fees for investment funds.

• Costs of maintaining rental properties, including repairs and agent fees.

  
  

For example, if you own a rental property, keep records of repairs like plumbing or painting, as these costs reduce your taxable rental income.

Use Tax Offsets and Rebates

Tax offsets reduce the amount of tax you pay, not your taxable income. Some common offsets include:

• Low and middle-income tax offset for eligible taxpayers.

• Private health insurance rebate if you have hospital cover.

• Superannuation contributions offset if you make after-tax contributions.

  
  

Check your eligibility for these offsets to reduce your tax bill further.

Keep Up to Date With ATO Changes

Tax laws can change yearly. In 2026, the ATO has updated some thresholds and rules, especially around work-from-home claims and small business deductions. Visit the official ATO website or consult a tax professional to stay informed and avoid mistakes.
