The interest on the loan for the home you live in is paid from after-tax income, and none of it is tax deductible. Interest on money borrowed to buy shares or other investments that earn assessable income can be. Debt recycling uses that difference.
Bad debt is non-tax-deductible debt, such as your home loan. Good debt is debt used to buy income-producing assets, where the interest may be deductible. You repay part of your home loan, borrow the same amount back through a separate investment loan, and invest it. Your total debt doesn’t grow, because you only re-borrow what you’ve already repaid.
Debt recycling in Australia is legitimate when it’s set up properly, and it’s easy to set up badly. Here is how the cycle works, what the ATO actually looks at, and when we’d tell a client to leave it alone.
What is debt recycling?
Debt recycling is a financial strategy for turning non-deductible home loan debt into tax-deductible debt over time. You pay down your home loan, redraw the amount you repaid through a separate investment loan split, and use those borrowed funds to invest in income-producing assets such as shares, ETFs, managed funds or an investment property. Income-producing assets are investments that generate income, such as dividends, distributions, or rent.
It suits people who were going to invest anyway. The tax benefits come from changing where the borrowed money sits and how it’s used. If you had no plan to invest, debt recycling adds investment risk you didn’t have before, and the potential tax benefits rarely justify that on their own.
How does debt recycling work? The five-step cycle
Debt recycling usually follows the same cycle, repeated over many years:
- Repay principal. Put surplus cash flow towards your home loan principal.
- Split the loan. Your lender sets up a home split and an investment split, each its own loan account.
- Draw what you repaid. Draw the amount you repaid from the investment split, and no more.
- Invest the borrowed funds. Send the money straight from the investment split to buy income-producing assets.
- Repeat. Put surplus cash flow and any investment income towards the home split, then start the next cycle.
You can run a cycle whenever you’ve built up a meaningful amount for repayment, for example, after a bonus or once a year. Each cycle adds investment exposure, so your investment risk grows with every round. A debt recycling strategy changes the mix of your debt, not its size.
What makes investment loan interest tax deductible?
The ATO’s rule is simple. If you borrow money to buy shares or other investments that earn dividends or other assessable income, you can claim a deduction for the interest. Only interest incurred for an income-producing purpose is deductible. If borrowed money is used for both private and income-producing purposes, the interest must be apportioned, and there’s no deduction against exempt income.
The ATO’s ruling on interest deductions, TR 95/25, explains how that test works. The character of the interest follows the use to which the borrowed funds are put, and tracing the money to an income-producing use shows the connection. What secures the loan doesn’t decide it. That’s why a loan secured against your home can incur deductible interest when the funds are used to buy shares. Interest is no longer deductible if the funds are no longer used to produce income.
Deductible interest reduces your taxable income. The tax savings depend on your marginal tax rate: each dollar of deductible investment loan interest cuts your tax bill by your marginal rate plus the 2% Medicare levy. For someone at a higher rate, that lowers the after-tax cost of investment debt relative to the after-tax cost of the same amount of home loan interest.
A registered tax agent confirms how these rules apply to your loans before you claim tax deductions.
Loan structure: split loans, redraw and offset accounts
The loan structure decides whether the interest on your investment debt stays deductible. Three facilities come up in every debt recycling conversation, and the ATO treats each one differently.
Why a separate investment split matters
Under TR 2000/2, when a loan facility is divided into sub-accounts, each used for a specific purpose, the interest on each sub-account follows its respective purpose. A clean investment split can remain fully deductible, provided the funds drawn from it are used solely for investment purposes.
A mixed account is harder. If a single loan account is used for both private and investment spending, the interest must be apportioned on a fair and reasonable basis, and repayments are applied proportionately across both uses. The ATO’s rental interest guidance is direct on this point: you can’t repay only the private portion, and the ratio continues for the life of the loan.
This is what people mean by “contaminating the loan”. The ATO’s own example is an investment loan redraw used to buy a TV and a lounge suite, which moves part of the loan out of the deductible share for good. The only clean fix TR 2000/2 accepts is refinancing a mixed loan into two separate loans that match the private and investment amounts.
Redraw
A redraw is treated as a new borrowing, and its character depends on how you use the redrawn money, whatever the original loan was for. If you redraw from a home loan to buy income-producing assets, the interest on that portion is typically tax-deductible. The ATO’s example of a home loan redraw used to pay the deposit on a rental property is deductible for that reason.
The catch is the mix. Redrawing into the home loan account itself turns it into a mixed-purpose loan, with the apportionment rules above. That’s why debt recycling uses a separate investment split rather than a redraw on the home loan.
Offset accounts
An offset account is a deposit account. Its balance reduces the interest charged on the linked loan, but it earns no interest of its own (TR 93/6). Because it’s your savings and not a loan, the ATO’s published rulings state that a withdrawal from an offset account is not a borrowing, so what you spend it on doesn’t change the character of the loan interest.
In practice, if you take savings out of your home loan offset and buy shares, you’ve invested your own money. The home loan interest stays non-deductible. To recycle offset savings, the money must first be applied to the home split to reduce the loan balance, then borrowed from the investment split.
The reverse also matters. Parking borrowed investment funds in an offset or savings account breaks the link to an income-producing use. The ATO’s example of a borrower who leaves part of an investment loan in a savings account for private purposes shows that the interest on that portion isn’t deductible. Draw from the investment split only when you’re ready to invest, and send it straight to your broker or platform account.
How debt recycling changes your position over time
With each cycle, the non-deductible home loan decreases and the investment split increases. Your total debt stays about the same while the mix shifts towards tax-deductible investment debt. Investment income can be reinvested in the next cycle.
The value of your investments and the size of your investment loan are separate things. Only the loan is fixed.
When markets rise
If your investments grow, you hold a smaller home loan, a growing investment portfolio and income you can recycle. That’s how the strategy can help some people build wealth over time. Nothing makes that outcome certain.
When markets fall
If your investments fall in value, the investment loan doesn’t fall with them. You still pay interest and repay the loan, and selling in a downturn locks in the loss. If rising interest rates or a drop in income arrive at the same time, cash flow can tighten within months. Managing cash flow through that period decides whether you can hold on. This is the scenario to plan for before you start, as it tests whether the structure suits you.
Pay off your home, invest spare cash or recycle debt?
These are the three realistic options for surplus cash, and each carries a different kind of risk.
Paying off your home reduces non-deductible debt and builds equity with no market risk. Every extra dollar saves interest at your home loan rate, and the savings are certain. It suits people who value certainty or have a short time frame.
Investing spare cash builds an investment portfolio without new borrowing. Your home loan stays where it is, and you take on market risk but no gearing risk. It suits people who want investment exposure but prefer not to borrow to get it.
Debt recycling does both: your home loan falls while your investments grow with borrowed funds. You carry market risk plus gearing risk, and the setup is more complex. It suits people who were investing anyway, with stable income and a long horizon.
If you’re also deciding between paying down your mortgage or adding to super, that choice sits alongside this one.
Benefits and risks of debt recycling
Debt recycling is a way of structuring debt, not an investment in itself, so the same investment risk applies as for any borrowing to invest.
[h3] Debt recycling benefits
- Your non-deductible home loan shrinks over time.
- Interest on the investment split may be deductible, turning bad debt into deductible debt.
- Surplus cash flow and investment income go to work in a diversified portfolio.
- It can support long-term wealth creation for people who would invest regardless.
The benefits of debt recycling rely on a clean structure and years of consistency.
The risks you carry
- Magnified losses. Borrowing to invest magnifies losses as well as gains. When market volatility drives investment values down, the loan balance remains unchanged.
- Interest rates. Rising interest rates increase the cost of the investment split and squeeze cash flow.
- Income. Losing your income while you carry investment debt is the biggest threat to the strategy. Your cash buffer and your income protection insurance matter more once you’re geared.
- Your home as security. The investment split is usually secured by your home equity. If repayments can’t be met, your home is at risk.
- Record-keeping. Errors in how money moves between accounts can reduce the deductible portion, and the ATO requires accurate records to calculate it.
- Behaviour. Selling in a downturn, or drawing more than you repaid, can undo years of work.
- Rule changes. Tax settings change over the life of a strategy that runs for decades, as the negative gearing and CGT reforms show.
Borrowing to invest can increase financial risk in ways that only show up in a bad year. It’s a long-term strategy, and a timeframe of at least five to ten years gives investments time to recover from a fall.
Who a debt recycling strategy may suit, and who it may not
It may suit people with:
- stable income and surplus cash flow each month
- an emergency buffer already in place
- a time horizon of at least five to ten years
- comfort holding investments through market swings
- the discipline to keep clean records.
It may not suit people with:
- tight cash flow or irregular income
- no cash buffer
- retirement close by, or a short time horizon
- low tolerance for losses
- plans to sell the home soon.
Whether debt recycling fits you depends on your personal circumstances, your loan, your financial goals and your comfort holding debt through a market fall. Our investment planning service looks at those together before any money moves.
Debt recycling vs negative gearing, and the rule changes
Debt recycling is about changing the type of debt you hold. Negative gearing describes an investment in which deductible costs, such as interest, exceed the income it earns, with the net loss reducing other taxable income, such as salary. A recycled investment can be positively or negatively geared. We cover the positives and negatives of gearing separately.
Negative gearing and capital gains tax changed in 2026. The ATO confirms that these measures are now law and apply from 1 July 2027. The Treasury explainer sets out the details:
- Negative gearing for residential property is limited to new builds.
- Established residential properties held at 7:30pm AEST on 12 May 2026 can keep being negatively geared until sold.
- Established residential properties bought after that time can be negatively geared only until 30 June 2027. From 1 July 2027, their rental losses can only be deducted against residential property income, including capital gains, with any excess carried forward.
- Shares and commercial property keep existing negative gearing arrangements.
- For individuals, trusts and partnerships, the 50% CGT discount will be replaced by cost base indexation and a 30% minimum tax on real gains from 1 July 2027. This applies to shares as well as property. Gains accrued before that date keep the discount.
For debt recycling, the core rule is unchanged. Interest on money borrowed to buy shares is still deductible under the ordinary rules, and those losses can still reduce your salary income. Property investments are where the changes bite. Recycling into an established residential investment property bought after the cut-off is now less tax-effective, because its rental losses can no longer offset your salary. Gains on any investment that accrue after 1 July 2027 are taxed under the new CGT rules when you sell.
So, can you still debt recycle in Australia? Yes. The reforms changed negative gearing on residential property and the CGT discount, not the tax deductibility of interest on money borrowed to invest.
Selling investments and winding down
Plan the exit as carefully as the start. If you sell investments purchased with the investment split and spend the proceeds privately while the loan remains in place, the borrowed funds are no longer used to generate income, and the interest generally ceases to be deductible. Using sale proceeds to repay the investment split keeps things clean. Every sale is also a CGT event, so the timing matters.
As retirement approaches, most people want their investment debt cleared before their employment income stops. A plan to reduce the investment split over your final working years is part of a sound investment strategy and should be included in the plan from the first cycle.
