What the New GIC/SIC Tax Deduction Rules Mean for You

Introduction

Proper tax planning and compliance are crucial for individuals and businesses in Australia. With tax laws continuously evolving, staying informed about changes that impact tax deductions and financial obligations is essential. One significant upcoming change is the denial of tax deductions for General Interest Charge (GIC) and Shortfall Interest Charge (SIC) from 1 July 2025. Understanding these changes and their potential impact can help taxpayers make informed financial decisions and avoid unnecessary costs.

Key Changes to GIC/SIC Deductions

From 1 July 2025, deductions for GIC and SIC incurred on tax debts will be denied. This change is aimed at encouraging timely tax payments and reducing collectable tax debt owed to the Australian Taxation Office (ATO). While the government aims to promote tax compliance, this new measure will significantly increase the financial burden on taxpayers with outstanding tax debts.

Understanding GIC and SIC

Currently, the ATO imposes two types of interest charges on overdue tax debts:
• GIC (General Interest Charge): Applied to unpaid tax liabilities, calculated as the 90-day Bank Accepted Bill rate plus an uplift of 7%.
• SIC (Shortfall Interest Charge): Applied to tax shortfalls due to incorrect self-assessment, calculated as the 90-day Bank Accepted Bill rate plus an uplift of 3%. The current rate for January-March 2025 is 7.42%.
Both charges are compounded daily and updated quarterly to reflect market borrowing rates. Currently, these costs are tax-deductible, reducing the effective financial burden on taxpayers. However, with the proposed changes, taxpayers will bear 100% of these costs, increasing the cost of outstanding tax debts.

Implications for Small Businesses and Individuals

These changes could significantly affect cash flow management and financial planning for businesses and individuals. Key impacts include:
• Higher Cost of Tax Debts: Without tax deductions, the real cost of GIC/SIC will increase substantially, making it more expensive to hold tax debt.
• Strain on Cash Flow: Small businesses, in particular, may struggle to secure alternative financing at more favorable rates.
• Reduced Incentive for Payment Plans: Taxpayers may need to reassess existing ATO payment plans or seek remission of charges to mitigate financial strain.
• Potential for Increased Business Failures: Businesses facing liquidity challenges may find it harder to sustain operations with higher tax-related costs.

Proactive Steps to Take Now

To avoid financial stress and minimise exposure to increased tax costs, businesses and individuals may consider the following strategies:
• Settle Existing Tax Debts: Paying off outstanding balances before 1 July 2025 can help avoid the impact of non-deductibility.
• Stay Up to Date with Lodgments: Ensuring all tax returns and activity statements are lodged on time can prevent unnecessary penalties and interest charges.
• Explore Alternative Financing Options: If tax debts must be carried, securing loans from financial institutions at lower interest rates than GIC/SIC may be a viable option.
• Engage with the ATO Early: Proactively discuss tax debts with the ATO to explore remission options or negotiate more manageable payment arrangements.
• Implement Strong Cash Flow Management: Budgeting and financial planning can help ensure tax liabilities are met on time, reducing reliance on ATO payment plans.

Looking Ahead

While the legislative process is still underway, businesses and individuals should prepare for the likely implementation of these changes. The government estimates that this measure will increase tax revenue by $500 million in 2026–27, indicating a strong commitment to its enforcement. Small businesses, which account for a significant portion of collectable tax debt, will need to carefully evaluate their tax compliance strategies to avoid financial hardship.
