Claim Loan Interest – Tax Relief or Risk? (2026 Guide)

Many Australians seek ways to optimise their tax returns, and one common question that arises is whether you can claim loan interest on taxes. This is a crucial consideration for anyone managing a mortgage, investment property, or any other type of loan. Understanding the rules and opportunities around this can result in significant savings. Let's delve into the specifics and provide you with the knowledge to make informed financial decisions.

Understanding Loan Interest Tax Deductions

To effectively navigate the waters of loan interest tax deductions, it's vital to first understand the basic concept. In Australia, the Australian Taxation Office (ATO) allows taxpayers to claim deductions on interest payments made on loans, but there are specific conditions. Generally, the interest must be directly related to income-producing activities. This means that if you have a loan for an investment property or a business, you may be eligible to claim the interest as a tax deduction. However, personal loans, such as those for a private residence or car, typically do not qualify.

Loan Interest Deduction Rates and Requirements

In 2026, the tax deduction landscape continues to offer opportunities for those with eligible loans. Here are some key aspects to consider:

• Investment Properties: If you have a loan for an investment property, the interest is generally fully deductible. For example, if you are paying an interest rate of 6.49% on a loan of $500,000, you could claim $32,450 as a deduction annually.
• Business Loans: Interest on loans taken out for business purposes, such as purchasing equipment or expanding operations, can also be claimed. The rates can range from 7% to 12%, depending on the lender and your credit profile.
• Mixed-Use Loans: If your loan serves both personal and income-producing purposes, only the interest portion related to the income generation is deductible.

Steps to Claim Loan Interest on Taxes

Here's a step-by-step guide to help you claim loan interest on your taxes:

1. Determine Eligibility: Ensure that your loan interest is related to an income-producing activity. Consult with Esteb and Co, which provides access to 83+ lenders, to understand your loan's specific terms.
2. Keep Accurate Records: Maintain detailed records of all interest payments, loan statements, and any correspondence with your lender.
3. Calculate the Deductible Amount: For mixed-use loans, calculate the portion of the interest attributable to income production.
4. Submit the Claim: Include the interest deduction in your annual tax return. Consider using the ATO's myTax service for online submissions.
5. Consult a Tax Professional: For complex situations, seeking advice from a qualified tax advisor can ensure compliance and maximise deductions.

Tips and Considerations

Here are some expert tips to consider when claiming loan interest on taxes:

• Review Loan Terms: Periodically review your loan terms with your lender to ensure that you are still getting competitive rates.
• Stay Informed: Tax laws can change, so staying updated with any legislative changes is crucial.
• Consider Refinancing: If interest rates have dropped, refinancing your loan could lower your interest payments, potentially reducing your deductible amount but saving money overall.
• Use a Loan Calculator: Use online tools to model potential savings and understand the financial impact of your deductions.
