What’s the Tax Impact of Refinancing to a Lower Rate?
In Australia, refinancing at a lower interest rate is one of the most popular financial decisions, especially when rates shift, and lenders start to provide better offers.
Lower loan repayments give you more money to spend, enable you to pay off your loan sooner than anticipated, or just relieve financial strain. On the other hand, people frequently wonder about the tax implications of refinancing.
How will the ATO handle the new loan? Are the refinance costs Is it deductible? Does it make a difference when money is taken out?
In Australia, the tax impact of refinancing depends not only on the interest rate but also on the type of property linked to the loan (your home or an investment). That’s why this article covers this segment thoroughly to provide valuable insights to the readers.

ATO Refinance Rules: Why Loan Purpose Determines Deductibility
Australian tax law usually uses the use of the borrowed funds as the basis for interest deductibility, not the security used for the loan. To put it in other words, the most important question is: Why was the money borrowed?
- Owner-Occupied Purpose: When the loan is connected to your main house, the interest is not normally tax-deductible.
- Investment Purpose: Interest on loans about income-producing properties, primarily investment properties, is typically deductible as long as the funds are utilized to produce assessable income.
Thus, when you refinance your owner-occupied loan at a lower rate, it is generally a very good financial idea—but it won’t normally have much impact on your tax status since you were not claiming the interest on the loan to begin with.
Refinancing Your Primary Residence (PPOR): Are There Tax Benefits?
For the majority of Australians who are refinancing their Principal Place of Residence (PPOR), the tax result is simple: you cannot deduct the interest, so refinancing does not alter your tax position.
Your monthly repayment may decrease, but as a rule, there is no tax break for paying less interest. It is a real benefit—a cash-flow benefit—but not a tax benefit.
When refinancing entails debt consolidation, homeowners may be caught off guard. Because the intent is still personal, interest on personal debts (such as credit card or auto loans) is not deductible even if you roll them into your home loan.
Interesting Facts
Upfront fees (“points”) paid to get a lower rate might be deductible, either fully in the year paid (if used to buy/improve a home) or amortised (spread out) over the loan’s life, depending on how they’re paid and used.
Refinancing Investment Property: Tax Deductions on Interest
When you refinance a loan secured by an investment property that generates rental income, the interest paid on that loan is usually deductible. While lower interest rates mean you will pay less interest (and thus claim a smaller tax deduction), that is normally a win regardless, since you are saving money overall.
More significant tax matters regarding investment property refinancing are typically:
- How much you raise the loan amount (equity release or cash-out).
- How you spend any additional funds you borrow.
- the handling of loan setup fees and refinance expenses.
This is where maintaining clean records and proper loan structuring is significant.
Tax on Equity Release: Is Cash-Out Refinancing Deductible?
The process of “tapping equity” through a larger loan and cash withdrawal is one of the most popular refinance strategies. The way you use the equity release will determine how much of this additional amount can be deducted as interest in Australia.
Typical outcomes:
- Income Generation: If the additional funds are used to generate income (e.g., purchasing an additional investment property or paying for investment-related expenses), the interest on that specific amount may be deductible.
- Personal Use: Interest on that amount is not deductible if you use the additional cash for personal purposes (e.g., holidays, a personal car, school fees, etc.).
This may form a mixed-purpose loan, where some of the interest is deductible and some is not. The ATO requires you to apportion the interest appropriately, which can become complicated when everything is lumped together in a single large loan balance.
One practical tip is to create separate loan “splits” to ensure that the deductible and non-deductible portions are not mixed.
Are Refinancing Costs and Borrowing Expenses Tax Deductible?
Refinancing involves costs, some paid upfront and others added to the loan. In Australia, most of these amounts are treated as borrowing expenses where they are attributable to income-generating borrowing (such as an investment property loan).
Common borrowing costs may include:
- Loan establishment fees.
- Lender legal fees.
- Mortgage broker fees (where applicable).
- Title search charges involved in establishing the loan.
Where they qualify as borrowing expenses, they are normally deductible over the shorter of:
- 5 years, or
- The term of the loan.
Thus, when refinancing an investment loan with a 30-year term, you usually allocate deductions for eligible borrowing expenses over a period of 5 years.
Other refinance expenses may not be deductible. For illustration, mortgage registration fees are frequently not treated in the same manner as interest, and some expenses can be capital in nature. Treatment may differ depending on the actual cost and circumstances, so it is worth classifying costs in detail using your settlement statement.
Loan Structuring for Tax Efficiency: Managing Mixed-Purpose Loans
Refinancing is also an opportunity to clean up your loan structure—offset accounts, redraw facilities, splits, and repayment distribution. Tax-wise, the most dangerous risk is combining personal and investment borrowing to a level that is difficult to untangle.
Some structure tips that tend to work (particularly for investment property owners):
- Use separate splits: Create specific loan splits for specific uses (e.g., Split A for the investment property, Split B for the private portion).
- Be careful with redraws: Redrawing funds for private spending later can contaminate the tax deductibility of the loan.
- Maintain records: Always document the application of borrowed money.
A good mortgage broker firm can help you plan the structure before you sign, ensuring you do not create a messy loan to apportion at tax time.
To save your accountant the hassle of sorting through your finances (and to make any audit process less stressful), you should retain:
- The refinance approval papers and loan agreement.
- Your itemized refinance costs and settlement statement.
- Break cost statements (where applicable).
- Bank statements showing where any equity release funds were paid and how they were used.
- A distinct record of what each loan split represents.
This is most important for owners of investment properties and anyone with mixed-purpose debt.
When to Seek Professional Tax Advice for Refinancing
If your refinance was for an owner-occupied home and you did not tap into equity, the tax aspect is usually minimal. However, if you refinanced an investment property, took cash out, paid break costs, or have a loan that has become “mixed-purpose,” a misjudgment can be costly.
In these cases, personalised tax advice is especially useful. The correct treatment will vary depending on the purpose of your refinance, your paperwork, and how the costs are classified under ATO guidelines.
Conclusion
In general, the purpose of the loan—rather than the lower rate—determines the tax impact in Australia.
It’s a wise financial decision to refinance to a lower rate, but how you use the borrowed funds and whether the loan is secured by your home or another productive asset will determine the tax ramifications.
Tax changes tend to be insignificant for your PPOR. For an investment property refinance, the interest remains deductible, financing expenses may be deductible over time, and equity release deductibility depends on usage. Therefore, structure and record-keeping are essential.
