The Australian Taxation Office (ATO) has advised that it will be increasing its review activity on individual tax returns lodged during the 2026 tax season.

As part of this, many individual taxpayers will receive a letter directly from the ATO before tax time. The purpose of the letter is to remind taxpayers of their obligations and advise that some tax returns may be selected for review before being processed.

While receiving a letter does not mean you have done anything wrong, it does indicate that the ATO will be paying closer attention to work-related expense claims this year.

What is changing?

The ATO has advised that it will be closely reviewing tax returns where work-related expense claims are significantly higher than expected for a taxpayer’s occupation and circumstances.

The ATO’s focus remains on ensuring that:

  • Deductions directly relate to earning income
  • Claims are supported by appropriate records
  • Tax returns are prepared accurately
  • Taxpayers can substantiate their claims if reviewed

This means taxpayers with higher deduction claims may be more likely to have their returns selected for verification.

What happens if your return is selected?

If your return is selected for review:

  • The ATO may stop the processing of your tax return.
  • The ATO will request supporting documentation to substantiate the claims being reviewed.
  • The requested information must generally be provided within 28 days.
  • If sufficient evidence cannot be provided within that timeframe, the ATO may adjust the relevant deductions before issuing your assessment.

The ATO has indicated that extensions will generally not be granted, as the required documentation should already be available when the tax return is lodged.

How can you prepare?

The best way to avoid delays is to ensure you have records to support any deductions you intend to claim before your tax return is lodged.

Depending on the deductions you claim, this may include:

  • Receipts and invoices
  • Logbooks
  • Travel records
  • Working from home records
  • Employer documentation

Remember, to claim a work-related deduction:

  1. You must have incurred the expense yourself.
  2. The expense must directly relate to earning your income.
  3. You must have records to support the claim.
