You’ve been paying off your home for years, and every dollar of interest goes straight out the door. No deduction, no tax benefit, nothing to show for it at tax time. So when someone mentions you can turn some of that debt into tax-deductible debt, it’s worth a closer look.
That’s the idea behind a debt recycling strategy. It’s not a trick, and it’s not for everyone. Done well, it gradually changes the type of debt you carry without adding to the total. Done badly, it can leave you with a messy loan and a deduction you can’t back up.
In this guide we’ll walk through how a debt recycling strategy works in plain English, what the ATO cares about, what has changed in 2026, and what to think about as a Gold Coast homeowner before you speak to your accountant and broker.
General information only. This isn’t tax, legal or investment advice, and it doesn’t take your personal situation into account.
So, what is debt recycling?
The tax rule behind it is simple. Interest on the loan for your own home isn’t deductible. Interest on money you borrow to buy things that earn income, like shares or ETFs, generally is. The ATO says you can claim interest on money borrowed to buy shares or other investments that earn dividends or other assessable income, but only for an income-producing purpose.
A debt recycling strategy simply uses that rule on purpose. You put spare cash into your home loan, then borrow the same amount again through a separate loan and invest it. The total you owe stays about the same, but over time more of it becomes deductible.
If your total debt grows, that’s no longer recycling. That’s borrowing to invest, and it carries a different level of risk.
How it works in real life
Here’s a made-up example. Sam and Jo live in Burleigh Waters. Their home is worth about $1.4 million and they owe $650,000. Sam receives a $50,000 bonus.
First comes the set-up. Before any money moves, they ask their broker to create a separate loan split for investing. Keeping home debt and investment debt apart makes the records much easier to follow.
Next, the $50,000 goes into the home loan, which drops to $600,000. Then they borrow $50,000 through the new split and use it to buy investments. Their total debt is still $650,000, but $50,000 of it is now investment debt.
When more spare cash turns up, they do it again. Most people recycle in stages over years, not in one big move.
The ATO rule every debt recycling strategy hangs on
Here’s the part people skip. The ATO cares about what the borrowed money was used for. It doesn’t care what property the loan is secured against.
In an ATO community reply, the ATO said interest on a new loan used to buy income-producing shares would be deductible, and that a redraw is treated as its own loan, pointing to Taxation Ruling TR 2000/2.
This is why structure matters so much. When one loan is used for more than one purpose, the interest has to be split between the deductible and non-deductible parts, and repayments generally have to be split too. So if you use a single investment split to buy shares and also fund a holiday, you can’t just aim your repayments at the holiday part. Unpicking it later is hard.
Keep your statements for every transaction. If the ATO ever asks, you want to show exactly where each borrowed dollar went.
What the numbers can look like
Let’s use illustrative figures only. Say you recycle $60,000 into an investment split at a hypothetical 6.5% p.a. That’s not a lender rate or offer. The interest is $3,900 a year.
- At a 30% marginal tax rate, the deduction is worth about $1,170, so the net cost is about $2,730.
- At a 37% marginal rate, the deduction is worth about $1,443, so the net cost is about $2,457.
These figures ignore the Medicare levy. The deduction softens the cost of borrowing, but it doesn’t remove it. In this example you’re still paying around $2,500 to $2,700 a year after tax, whether markets rise or fall. Your investments need to beat that after tax, once tax on dividends and gains is counted. Advisers also point out that losses can compound when markets fall, and that interest rates on these facilities are often higher.
Offset or debt recycling?
This one comes up a lot, and it’s a fair question. An offset account reduces the interest on your home loan at the loan rate, and you can pull the money out whenever you need it. That flexibility is worth a lot.
But money in an offset isn’t borrowed money. Advisers give the example of withdrawing offset funds for a rental deposit, which doesn’t make home loan interest deductible, whereas redrawing from the loan itself for that purpose can.
So recycling trades some of that flexibility for a possible deduction and the chance of investment returns, and it brings market risk with it. If you might need the cash for school fees, a renovation or a rainy day, the offset may suit you better. It’s worth being honest with yourself about that.
Why a debt recycling strategy looks different on the Gold Coast
Plenty of owners have plenty of equity. PRD’s market update puts the Gold Coast median house price above $1.4 million in the June 2026 quarter, almost 65% higher than five years earlier. But equity isn’t the same as borrowing capacity.
Lenders are being cautious. The RBA lifted the cash rate to 4.60% on 29 September 2026, the fourth rise this year. APRA has kept the serviceability buffer at three percentage points, so borrowers are being assessed at rates above 9%. A new investment split is usually assessed like any other credit request, even when your total debt isn’t rising. The MFAA’s August survey found 49.2% of brokers were seeing more clients unable to refinance because of serviceability, up from 24.4% six months earlier.
Business owners face extra scrutiny. If you run a business, lenders look closely at how your income is documented. That’s why your bookkeeping can affect your loan approval chances just as much as the loan setup does.
What changed in 2026
Three things sit on top of any debt recycling strategy this year.
Higher rates. Each rise lifts the cost of the investment loan, which raises the return your investments need to beat.
A new CGT regime. Legislation replacing the 50% CGT discount with cost base indexation and a 30% minimum tax on capital gains has passed both houses of Parliament. It applies to all CGT assets, including shares, and only to gains accruing from 1 July 2027. The existing 50% discount still applies to gains made before that date. Controversial CGT changes clear both houses of parliament +2
Negative gearing limits. If you already owned an investment property before 7:30pm on 12 May 2026, nothing changes for you. New builds are unaffected, and so are shares and commercial property. So interest on money borrowed for shares isn’t caught by the residential property rule. If your recycled funds were going into established residential property, different rules and transition dates apply. A second tranche of legislation was also open for consultation until 21 August 2026, so the fine print may still move.
These are tax questions for your accountant or a licensed financial adviser, not something a broker can answer.
What we look at when you’re considering a debt recycling strategy
We can’t give tax advice or tell you what to invest in. What we can do is look at the lending side with you:
- Whether your lender allows separate splits for different purposes, and what they charge for them.
- Whether the new split needs a fresh credit assessment and valuation.
- How the serviceability buffer affects what you can access.
- Whether debt-to-income limits matter for you. Since February 2026, APRA’s limit allows banks and other ADIs to write only 20% of new mortgage lending at six times income or more. Non-bank lenders aren’t subject to that cap. A pure recycling cycle shouldn’t increase your total debt, but a top-up might.
- Whether restructuring means refinancing, and what it could cost, including break costs on a fixed rate.
Lending criteria, rates and policies vary between lenders. Our post on split loans explains how splits work from a lending point of view.
Mistakes we’d steer you away from
Most problems come from a few habits:
- Using one account for everything. If investing and private spending go through the same split, you’ve created a mixed-purpose loan.
- Borrowing extra. Adding debt on top of your mortgage is gearing, not recycling.
- Assuming the home loan makes it deductible. Security doesn’t decide the outcome. Purpose does.
- Thin buffers. In a rising-rate year, a debt recycling strategy only works if you can comfortably cover repayments on the whole loan, not just the investment split.
- Short time frames. Markets can fall while the debt stays exactly where it is.
Is it for you?
A debt recycling strategy tends to suit people with steady income, regular spare cash and a long time frame, who can watch a share portfolio drop without panic-selling. It’s usually a poor fit if repayments are already tight, if your income swings and you hold little in reserve, or if you’d need the money back in a few years.
Sometimes the better move is the simpler one: build your buffer, sort your insurance, or keep the cash in your offset for now.
Quick answers
Is a debt recycling strategy legal in Australia?
Yes. It applies the ordinary rule that interest is deductible when borrowed money is used to earn assessable income. Whether your deduction stands up depends on your facts and your records.
Do I need a separate loan split?
Separate accounts make the transactions easier to follow, but they don’t decide the tax result. The purpose of each borrowing is what counts. A clean split just makes that easier to prove.
Do the CGT changes mean a debt recycling strategy no longer works?
Not automatically. They change the after-tax return on future gains, which is why your accountant should model your own numbers.

The bottom line
A debt recycling strategy can be a smart way to put long-held Gold Coast equity to work, but it rewards careful set-up and punishes shortcuts. The structure, the records and your cash-flow buffer matter as much as what you invest in. With rates higher and the tax rules shifting, it’s worth getting the lending side checked before any money moves.
