Updated: Nov 19, 2025
From 1 July 2025, the rules regarding deductibility of ATO tax debt will undergo significant changes. Businesses will no longer be able to claim deductions on interest incurred from outstanding ATO tax debts. For many businesses already managing cash flow pressures, this shift could mean higher effective costs if tax liabilities remain unpaid.
What Does This Mean for Businesses? - ATO Tax Debt
Previously, interest charged by the ATO on overdue tax debts could be claimed as a business expense. From July 2025, this option will no longer be available. This means that every dollar of interest charged by the ATO will now come straight off your bottom line.
The Financial Implications
The financial implications of this change are significant. Businesses with ongoing or legacy tax debt will see increased costs. Cash flow will become tighter if tax arrears are not managed proactively. Relying on the ATO as a source of short-term credit will become even more expensive.
Preparing for the Changes
To prepare for these changes, businesses should evaluate their current tax obligations. Understanding your tax position now can help you make informed decisions before the new rules take effect.
Why This Matters
Businesses with ongoing or legacy tax debt will see increased costs.
Cash flow will become tighter if tax arrears are not managed proactively.
Relying on the ATO as a source of short-term credit will become even more expensive.
