Interest on ATO debts are no longer deductible.

Starting 1 July 2025, the ATO will introduce a significant change that will affect small businesses, sole traders, and individual taxpayers with unpaid tax debts. Interest charged on outstanding tax—known as the General Interest Charge (GIC)—will no longer be tax-deductible, creating a potential financial burden for many. 

 

How the change works. 

Currently, interest on unpaid tax debts can be claimed as a deduction, offsetting some of the cost against taxable income. From July 1, 2025, this will no longer be allowed. With the GIC rate at 11.17% per year, a $100,000 tax debt could cost $11,700 annually—entirely non-deductible. For taxpayers already stretched to their limits, this is a substantial new expense.

 

The rule change will particularly affect, small business owners and sole traders, individuals on payment plans who owe personal tax, and property investors who miss BAS or PAYG instalments.

 

Many taxpayers use outstanding tax payments to manage cash flow and fund business operations. Removing the deductibility of GIC adds a layer of financial pressure that could contribute to business failure or, in extreme cases, bankruptcy. If this is you, you should contact us so we can discuss your options with you. 

 

Strategies to manage the impact. 

Some taxpayers may consider borrowing funds to pay off their ATO debt, as interest on the loan could potentially be claimed as a tax deduction. However, the borrowed funds must be used for income-producing purposes, and the loan must be properly structured and documented. Simply taking out a loan to clear a tax debt does not automatically make the interest deductible.

 

In any case, borrowing may not even be an option for you. Those with ATO debts often owe because their finances are already stretched to the limit. 

 

Professional advice is critical. 

With the GIC and shortfall interest charge in play, seeking expert guidance is essential. A qualified tax agent can:

 

  • Review your current tax obligations. 
  • Explore potential strategies to minimise financial impact. 
  • Ensure any loan or payment arrangement is structured correctly for deductibility. 



Early advice and planning can make a real difference in managing cash flow and avoiding unexpected penalties. Don’t wait —let us help you now to protect your business and personal finances.

A new way to claim work-related expenses is coming for the 2027 tax return — but there is an important catch. From 1 July 2026, eligible taxpayers can claim a standard deduction of up to $1,000 for certain work-related expenses, without having to substantiate each expense individually. Sounds simple enough. But before you assume you can claim $1,000 on top of everything else, there are a few things you need to know. The $1,000 Is the Maximum The new standard deduction is capped at $1,000. It is designed to cover certain common work-related expenses, such as work-related phone and internet, home office expenses, stationery and some travel expenses. You can't claim the $1,000 and then claim those same expenses again separately. If you have actual work-related expenses of more than $1,000, you can continue to claim your actual expenses under the existing rules, provided you meet the requirements and have the records to support them. Do I Still Need to Keep My Receipts? Yes: and this is where it is worth being organised. If you use the standard deduction, you don't need to substantiate the individual expenses covered by it. But if you think your actual work-related expenses could be more than $1,000, keeping your receipts and records throughout the year will allow you to claim your actual expenses instead. There are also some deductions that aren't covered by the standard deduction and can still be claimed separately if you are eligible. It's for Your 2027 Tax Return The new deduction applies from the 2026–27 financial year, so you won't use it for the tax return you are preparing now. It will first apply to your 2027 tax return, lodged from July 2027. Is the $1,000 a $1,000 Tax Refund? No. The $1,000 is a deduction from your taxable income. It doesn't mean you'll receive an extra $1,000 back from the ATO. The value of the deduction will depend on your individual tax circumstances. What Should You Do Now? The best thing you can do is keep track of your work-related expenses throughout the 2026–27 financial year. When it comes time to prepare your 2027 tax return, we can look at your circumstances and determine whether the standard deduction or claiming your actual expenses is likely to give you the better outcome.  At Ascent Accountants, we can help you make sense of the new rules and make sure you're claiming the deductions you're entitled to: without claiming the same expense twice!
