What's New for Tax Returns in 2026?

This year, the Australian Taxation Office (ATO) has rolled out several changes impacting individuals and small businesses. Some of the key 2026 updates include:

  • Stage 3 Tax Cuts: From July 2024, the new personal income tax brackets mean more take-home pay for most Australians. If you’re earning between $45,000 and $135,000, your marginal tax rate has dropped, impacting your end-of-year assessment.

  • Revised Work-From-Home Deductions: The ATO’s fixed rate method now sits at 67 cents per hour, but only covers running expenses. You’ll need detailed records—think timesheets, rosters, or diaries—to claim this deduction in 2026.

  • Expanded Pre-fill Data: The ATO has broadened its data-matching, so more information (like private health, bank interest, and share dividends) appears automatically in your myGov account, streamlining the lodgement process.

Maximising Your Tax Return: Key Strategies

There’s more to a healthy tax refund than ticking boxes. Here are proven tactics to ensure you claim everything you’re entitled to:

  • Claim All Eligible Deductions: From self-education and professional memberships to work tools and protective clothing, know what counts for your industry. For example, tradies can claim tools, while teachers can claim union fees and classroom supplies.

  • Track Investment-Related Expenses: If you own shares or rental property, remember to include costs like interest on loans, management fees, and even travel (for inspections). With property values fluctuating, capital gains calculations matter more than ever in 2026.

  • Leverage Super Contributions: Voluntary after-tax super contributions can be tax-deductible. With the concessional cap now at $30,000, there’s more room to boost your retirement and your refund.

  • Donations and Gifts: Donations over $2 to registered charities are deductible—just keep your receipts.

Common Tax Return Mistakes and How to Avoid Them

Even experienced filers can slip up, especially with evolving ATO rules. Here’s what to watch for in 2026:

  • Missing Income: The ATO’s data-matching is sharper than ever. Forgetting to declare gig economy income (like Uber or Airtasker) or investment returns is a red flag.

  • Overclaiming Deductions: The ATO is scrutinising work-from-home and car expense claims. Only claim what you can prove—and ensure records match your claim method.

  • Lodging Too Early: Pre-fill data continues to be updated through July. Lodging before all your income data is available can result in errors and ATO amendments.

Tax Return Lodgement: DIY or Use a Pro?

With digital lodgement through myGov, more Australians are self-filing than ever. However, complex tax affairs—investment properties, trusts, or freelance income—may benefit from a registered tax agent. The ATO’s crackdown on incorrect claims means professional advice can pay for itself.

Key lodgement dates for 2026:

  • Self-lodgers: 31 October 2026

  • Tax agent clients: Usually 15 May 2026 (if registered with an agent by 31 October 2026)
