5 Tripping Hazards You Could Encounter During Tax Time

Even the most financially savvy Australians can fall into hidden tax traps. 

On the surface, many tax matters seem straightforward, but subtle complexities in the law can turn an innocent oversight into a costly mistake. That’s why it’s often encouraged for you to look beyond the obvious and be alert to areas where the ATO takes a closer look.

  1. Work-Related Deductions
    Work expenses are one of the most common sources of error. While individuals may assume they can claim items like home office equipment, travel, or clothing, the rules are strict. For example, conventional clothes—even if only worn for work—are not deductible, and travel from home to work is generally private in nature. Over-claiming can attract unwanted ATO attention.
  2. Investment Property Expenses
    Australians love property investment, but rental deductions can be a minefield. Common traps include incorrectly apportioning loan interest when part of the borrowing is used for private purposes, or claiming repairs that are actually capital improvements. The ATO also closely monitors holiday rentals, particularly where private use isn’t properly accounted for.
  3. Capital Gains Tax (CGT)
    Selling assets such as shares, investment properties, or even cryptocurrency can trigger capital gains tax. A common trap is assuming the main residence exemption automatically applies to all home sales, or forgetting to declare gains from digital assets. Even timing the sale incorrectly can cost thousands if concessions are overlooked.
  4. Superannuation Contributions
    Super is a powerful wealth-building tool, but contribution caps are strictly enforced. Accidentally exceeding concessional or non-concessional caps can result in extra tax and penalties. Another trap is assuming contributions are deductible without meeting the required notice and acknowledgment process.
  5. Side Hustles and the Sharing Economy
    Income from platforms like Airbnb, Uber, or online freelancing is taxable. Many individuals mistakenly assume that if payments are small or irregular, they don’t need to be declared. The ATO now receives data directly from these platforms, so undeclared earnings are quickly flagged.

The Bottom Line

Tax in Australia is full of complexities, and even those with a good grasp of the basics can stumble. The safest way to avoid these traps is to seek professional advice early, especially before making big financial decisions.
