What Are the Rules for Claiming Debt Recycling Interest?

Interest on a debt recycling loan can be tax deductible, but only when the borrowed money is used to buy income-producing investments. The ATO looks at what you did with the money, not which property secures the loan.

For Perth home owners, that one rule shapes how a debt recycling strategy is set up. Get the structure right and the claim is clear. Get it wrong and the deduction can shrink or disappear.

Is Debt Recycling Interest Tax Deductible?

Interest is deductible when the borrowed funds are used for an income-producing purpose, such as buying shares or an investment property. Under the ATO's tracing rule, deductibility depends on how the borrowed funds were used, not the security offered.

That is why debt recycling works as a way to convert non-deductible debt into deductible debt. Your home loan interest is a private cost and is not deductible. A new loan used to invest is a different story. Your home can still be the security, but the purpose of the new borrowing decides the tax treatment.

The deduction applies to the interest only. Principal repayments are not deductible, so you should never treat your full loan repayment as a tax claim.

How a Split Loan Structure Protects Your Deduction

A separate loan split for each purpose keeps your investment interest clear and easy to claim. When the investment split is used only for investing, the interest on it can be claimed in full, subject to your circumstances.

The risk of mixing is real. Using a loan for anything other than its intended purpose makes it a mixed purpose account, and the interest must then be divided among the different purposes. Under TR 2000/2, there is an ongoing need to apportion interest on a mixed purpose loan account.

This is the main reason a debt recycling loan structure usually uses a home loan with several splits instead of one large balance. The trade-off is some extra set-up and admin, and lenders differ in how many splits they allow and in their fees, so check your lender's product terms. Your broker can check what your lender allows.

Debt Recycling Interest Example at 6.75%

In a scenario like this, a Perth home owner moves $50,000 from savings onto their home loan and borrows the same amount through a new split to invest. At an illustrative rate of 6.75% p.a., interest on that $50,000 is about $3,375 over a year.

Here is how it plays out. The owner has a $400,000 home loan and $50,000 in savings. They pay the $50,000 into the home loan, which lowers the non-deductible debt. They then draw $50,000 from a new, separate split and invest it in a diversified share portfolio. Every dollar of that split has one purpose, so the interest of about $3,375 is clearly linked to the investment.

At tax time, the owner gives their accountant the loan statements and investment records. The accountant works out the claim, and the actual tax benefit depends on the owner's income and other circumstances.

The cost is that the $3,375 is still paid out of pocket each year. A deduction reduces the tax bill but does not cover the interest. If the investment earns less than the interest, or falls in value, the owner is still liable for the loan. The illustrative rate is not a forecast, and your own rate will depend on your lender and your loan.

Why Redraws and Refinancing Can Weaken Your Claim

Redrawing from a loan for personal spending can make that loan mixed purpose, and the interest must then be apportioned. Under TR 2000/2, the position can sometimes be fixed by refinancing into separate splits that match the investment and private portions, or by repaying recouped funds. Ask your accountant to confirm what applies to you.

Where redraw is used for investing, the position is different. Interest on a redraw depends on how the redrawn funds are used (TR 2000/2). Redraw can work, but a clean paper trail matters more with it than with a separate split.

Refinancing needs care too. A refinance that rolls investment and private debt into one loan can create a mixed purpose balance that you must apportion every year. If you refinance, ask your broker to keep the investment and home portions in separate splits from the start.

Offset accounts are handled differently. Withdrawing money from an offset account does not impact the deductibility of interest on the loan account. Always confirm how this applies to your loan with your accountant.

What Records Do You Need for ATO Compliance?

You need records showing what each loan split was used for and when the money moved. The ATO matches loan data, so your paperwork should line up with your claim.

In practice, that means keeping the statements for each split, the contract notes or purchase records for the investments, and a note of the dates funds moved between accounts. If you ever change how a split is used, record it at the time.

Claims that do not match the loan purpose or redraw activity can attract attention.

Your accountant should confirm what you can claim. Tax outcomes depend on your personal situation, and nothing here is tax advice.

Who Should Think Twice About Debt Recycling?

Debt recycling suits people with stable income who can cover the loan repayments and ride out falls in investment value. It is less suitable if a market fall or a rise in repayments would put real pressure on your budget.

The approach is for home owners with equity or spare cash, such as those with a growing family or a single high income. The main risks are that investments can lose value, that rates can rise, and that the claim depends on keeping the structure clean. A debt recycling calculator can help you test different repayment scenarios before you commit.
