Refinancing an investment property is a common strategy used by property investors in Australia. Many people refinance their loans to get a lower interest rate, better loan features, or to access extra money (equity). However, while refinancing can help you financially, it is very important to understand its tax implications.
In simple words, refinancing itself is not taxed, but it can affect how much tax you pay and how much deduction you can claim. If you do not understand the rules properly, you may lose tax benefits or face problems later.
In this blog, we will explain everything in very easy language about Refinancing investment property tax implications Australia, including examples and calculations, so you can clearly understand how refinancing affects your taxes in Australia.
What is Refinancing an Investment Property?
Refinancing means replacing your current home loan with a new loan. This can be done with the same lender or a different lender.
Common reasons for refinancing
- To reduce interest rate
- To lower monthly repayments
- To get better loan terms
- To access extra money (equity)
- To invest in another property
Is Refinancing Taxable in Australia?
The simple answer is:
👉 No, refinancing itself is not a taxable event
You do not pay tax just because you refinance your loan.
However, refinancing can affect:
- Your interest deductions
- Your taxable income
- Your future capital gains tax (CGT)
So, understanding the rules is very important.
The Most Important Rule: Purpose of Loan
In Australia, the most important rule is:
👉 Tax deduction depends on how you use the money, not the loan itself
This means:
- If money is used to earn income → deductible
- If money is used for personal use → not deductible
Interest Deductibility After Refinancing
When Interest is Fully Deductible
You can claim interest as a tax deduction if:
- The loan is used to buy an investment property
- The loan is used for rental property expenses
- The loan is used for property renovation
Example
- Original loan: $400,000 (investment property)
- Interest rate: 6%
- Annual interest: $24,000
👉 This $24,000 is fully deductible.
Now you refinance:
- New loan: $400,000
- Still used for investment property
👉 Interest remains fully deductible.
When Interest is NOT Fully Deductible
If you use part of the loan for personal purposes, you cannot claim full deduction.
Example 2
- Refinanced loan: $500,000
- $400,000 → investment property
- $100,000 → car purchase
Total interest = $30,000 per year
Now calculate deductible portion:
Deductible Interest =
$30,000 × (400,000 ÷ 500,000)
= $30,000 × 0.8
= $24,000 deductible
👉 Remaining $6,000 is NOT deductible.
Cash-Out Refinancing Explained
Cash-out refinancing means borrowing more than your existing loan and taking extra cash.
Scenario 1: Deductible Use
If you use extra money for:
- Buying another property
- Investing in shares
- Renovating rental property
👉 Interest is deductible
Example
- Old loan: $300,000
- New loan: $450,000
- Extra $150,000 used to buy another rental property
👉 Full interest on $450,000 is deductible.
Scenario 2: Non-Deductible Use
If you use extra money for:
- Buying a car
- Going on vacation
- Personal expenses
👉 That portion is NOT deductible
Example
- Loan: $450,000
- $300,000 → investment
- $150,000 → personal use
If annual interest = $27,000:
Deductible =
$27,000 × (300,000 ÷ 450,000)
= $27,000 × 0.67
= $18,090 deductible
Refinancing Costs and Tax Deductions
When you refinance, you pay some fees. The good news is that many of these costs are tax-deductible.
Common Deductible Costs
- Loan application fees
- Legal fees
- Valuation fees
- Mortgage broker fees
- Title search fees
- Lender’s mortgage insurance
How to Claim These Costs
Rule 1
If total cost is more than $100:
👉 Deduct over 5 years or loan term (whichever is shorter)
Rule 2
If cost is less than $100:
👉 Claim full amount in same year
Example
- Total refinancing cost = $2,000
- Loan term = 10 years
You can claim over 5 years:
$2,000 ÷ 5 = $400 per year deduction
Break Fees and Exit Costs
If you refinance a fixed-rate loan, you may pay a break fee.
👉 This fee is also tax-deductible
Example
- Break fee = $3,000
This amount is usually:
- Claimed over 5 years
OR - Added to loan costs
Capital Gains Tax (CGT) and Refinancing
Does Refinancing Trigger CGT?
👉 No, refinancing does NOT trigger capital gains tax.
You only pay CGT when:
- You sell the property
Important Point
Some refinancing costs:
- Cannot be claimed immediately
- Can be added to the cost base
👉 This helps reduce future CGT
Example
- Purchase price = $500,000
- Refinancing costs added = $5,000
New cost base = $505,000
If you sell for $700,000:
Capital Gain =
$700,000 – $505,000
= $195,000
👉 Lower gain = lower tax
Loan Splitting and Tax Planning
Loan splitting means dividing your loan into parts for different purposes.
Why It is Important
If you mix:
- Investment funds
- Personal funds
👉 It becomes difficult to calculate tax deductions.
Example (Bad Practice)
- One loan: $500,000
- Mixed use
👉 Hard to track deductions
Example (Good Practice)
- Loan 1: $400,000 (investment)
- Loan 2: $100,000 (personal)
👉 Easy to calculate deductions
Common Mistakes to Avoid
Many investors make mistakes while refinancing.
Avoid these errors
- Claiming full interest for mixed loans
- Using loan for personal use but claiming deduction
- Not keeping records
- Not splitting loans
- Ignoring tax rules
👉 These mistakes can lead to penalties.
Benefits of Refinancing (Tax Perspective)
Refinancing can provide many benefits:
✔ Tax Advantages
- Continued interest deductions
- Deduction on loan costs
- Better cash flow
- Ability to invest more
Risks of Refinancing
⚠️ Be careful about
- Losing tax benefits
- Incorrect calculations
- Mixed loan usage
- Higher loan amount
Practical Calculation Example (Full Scenario)
Example
- Original loan: $350,000
- Refinance loan: $500,000
Usage:
- $350,000 → investment
- $150,000 → personal
Interest rate: 6%
Annual interest =
$500,000 × 6% = $30,000
Deductible interest =
$30,000 × (350,000 ÷ 500,000)
= $30,000 × 0.7
= $21,000 deductible
Non-deductible = $9,000
