Changes to ATO Interest Deductions

Interest rate and taxation concept relating to ATO interest deduction changes.

What This Means for Your Business

ATO interest charges are no longer tax deductible.

Here is what this means for your business and how to avoid unnecessary costs.

What Has Changed

Previously, interest charged by the ATO could be claimed as a tax deduction.

This is no longer the case.

The change applies to:

  • General Interest Charge on overdue tax

  • Shortfall Interest Charge on tax underpayments

This means businesses now bear the full cost of these charges without any tax benefit.

Why This Matters for Your Business

Without deductibility, ATO interest charges become more expensive.

This can impact:

  • Cashflow

  • Profitability

  • Overall tax position

What was previously a partially deductible expense is now a direct cost to your business.

Common Situations Where Interest Applies

ATO interest charges may arise when:

  • BAS or tax returns are lodged late

  • Tax liabilities are paid after the due date

  • Amendments result in additional tax payable

  • Payment arrangements are in place with the ATO

Understanding when interest applies can help you avoid unnecessary costs.

How to Reduce Exposure to Interest Charges

To minimise the impact of these changes:

  • Lodge returns on time

  • Pay tax liabilities by the due date

  • Monitor your tax position regularly

  • Address any issues early

  • Seek advice if you are unsure about upcoming obligations

Taking a proactive approach helps reduce risk and maintain control over your financial position.


Need Support Managing Tax Obligations

Managing tax deadlines and cashflow can be challenging, particularly during periods of growth or change.

If you are concerned about outstanding tax liabilities or potential interest charges, early advice can help you stay on track and avoid unnecessary costs.
