Changes To Deductibility of ATO Interest Charges

Attention all taxpayers! The Australian Taxation Office (ATO) has announced significant changes to the rules surrounding the deductibility of interest charges. Set to take effect from 1 July 2025, these changes will impact anyone who incurs General Interest Charges (GIC) and Shortfall Interest Charges (SIC) due to late payments or underpayments.

What’s Changing?

Starting 1 July 2025, any GIC and SIC incurred will no longer be tax-deductible. This means that if you face interest charges for late payments or underpayments to the ATO after this date, you won’t be able to claim a deduction for that interest when filing your taxes.

The ATO has stated that this change is designed to promote fairness and equity among taxpayers, ensuring that those who meet their obligations on time are not disadvantaged.

What’s Staying the Same?

It’s important to note that the ATO’s remission process remains unchanged. Taxpayers can still request the ATO to remit (cancel or reduce) interest charges under certain circumstances. If you believe you have valid reasons for seeking a remission of interest, you can still apply through the appropriate channels.

Understanding the Impact

This change will undoubtedly make interest charges even more expensive for taxpayers who fall behind on their payments. To illustrate the impact, let’s look at an example.

Example Calculation

Currently (as of June 2025), the GIC rate is 11.17%. Suppose a taxpayer owes $1000 and incurs interest for late payment.

1. Calculate the annual interest paid:
   • Interest = $1000 x 11.17% = $111.70
2. Determine the tax savings if the interest were deductible (assuming a 30% tax rate):
   • Tax Savings = $111.70 x 30% = $33.51
3. Calculate the after-tax cost of the interest if it were deductible:
   • After-tax cost (deductible) = $111.70 - $33.51 = $78.19

However, since the interest will no longer be deductible from 1 July 2025, the full interest amount becomes the after-tax cost:

• After-tax cost (non-deductible) = $111.70

As you can see, the change significantly increases (by 42.8%) the financial burden of late payments. Run the same calculation for an individual with a tax rate of 45% and the additional financial burden grows by 81.82%.

What Does This Mean for You?

This regulatory change underscores the importance of meeting your tax obligations on time. To avoid these increased costs:

• Ensure timely payment: Plan ahead and ensure that you pay your taxes by the due dates.
• Stay informed: Keep up-to-date with tax deadlines and any changes in regulations.
• Seek advice: If you are struggling to meet your obligations, seek advice from a registered tax professional or accountant.

This update aims to bring greater compliance and fairness within the tax system. Therefore, being proactive in managing your tax responsibilities is vital to avoid any financial impact due to late payments.
