What Documents are Needed to Prepare Your Tax Return in 2025?

  • Income statements from employers or payslips
  • Bank statements showing interest earned and deductions
  • Receipts for work-related deductions such as uniforms, tools, or travel expenses
  • Private health insurance statements to determine eligibility for rebates
  • Investment income records, including dividends, rental property income, and capital gains
  • Business income and expense records if you are self-employed or a freelancer

Having these documents ready before starting your tax return helps prevent errors and ensures you claim all deductions legally available to you.

Understanding Tax Deductions in Australia for 2024-2025

Claiming tax deductions can lower your taxable income and increase your refund. However, deductions must be directly related to earning your income and supported by records. Common deductions include:

  • Work-related expenses such as uniforms, safety gear, tools, and vehicle costs for work-related travel (excluding commuting to and from work).
  • Home office expenses if you work from home, covering a portion of electricity, internet, depreciation of office equipment, and work-related phone usage.
  • Self-education costs related to improving your work skills, including course fees, textbooks, and stationery.
  • Investment expenses like interest on loans for investment properties, financial advisor fees, and property maintenance.

Understanding what you can claim helps you avoid over- or under-claiming, which could trigger an ATO review.

How to Get the Most from Your Tax Return

Maximising your tax return starts with good record-keeping. Throughout the year, track all work-related expenses and store receipts digitally or in a folder. The ATO provides deduction guides for different industries, so check what applies to your job to avoid missing potential claims.

Consider all tax offsets and rebates you may qualify for. These could include private health insurance rebates, low-income tax offsets, and deductions for charitable donations. Reviewing available offsets ensures you claim everything you’re entitled to.

Lodging your return correctly also plays a role in optimising your refund. Double-check all figures, ensure your details match ATO records, and seek professional help if your situation is complex. If you are unsure about any claims, a tax agent can help you get the most from your return while ensuring compliance with tax laws.

Step 5: Review and Submit

Check all details for accuracy before submission. Errors can delay your refund or result in ATO audits.

Common Tax Return Mistakes to Avoid

Overclaiming deductions is one of the most common tax return mistakes. Claiming expenses that are not directly related to your work, or failing to keep receipts, can lead to audits and repayment of excess refunds. Ensure all deductions are eligible and have supporting evidence.

Failing to report all income is another frequent issue. The ATO receives financial data from banks, employers, and investment institutions. Omitting bank interest, rental income, or freelance earnings can trigger red flags and lead to penalties.

Simple errors such as incorrect tax file numbers (TFN), bank account details, or employer information can delay processing. Always review your tax return before submitting to avoid mistakes that could hold up your refund.

Tools and Resources to Help with Lodgement

The ATO website has tools that provide official tax lodgement services, deduction checklists, and tax calculators. Tax calculators help estimate refunds and liabilities based on income and deductions.

Record-keeping apps assist with tracking work-related expenses, making tax time easier.
