How to turn your home loan into a tax-deductible investment strategy — the real mechanics, real numbers, the risks nobody puts in the headline, and a free calculator that models your own numbers in under two minutes.
Debt recycling converts your non-deductible home loan debt into tax-deductible investment debt, without increasing your total debt. You pay down your home loan, then redraw that same amount through a separate, clearly identified investment loan split. That money goes into income-producing assets — typically shares, ETFs, or property. The interest on the investment loan is generally tax-deductible, and the tax refund plus any investment income gets redirected straight back onto your home loan, accelerating its payoff while a portfolio compounds alongside it. It's a long-term, high-discipline strategy best suited to homeowners with stable income, spare equity, and a 10+ year horizon — not a quick win, and not for everyone.
Debt recycling is a strategy that swaps non-deductible home loan debt for tax-deductible investment debt, one dollar at a time, without increasing your total borrowings. Home loan interest on your own house gets you no tax benefit at all. Interest on money borrowed to buy income-producing assets — shares, ETFs, managed funds, an investment property — generally does. Debt recycling exploits that gap: you gradually shift the mix of your debt from the first kind to the second, while building an investment portfolio at the same time.
It is not a way to borrow more. Your total debt stays the same throughout the cycle — what changes is which portion of it is deductible. That single distinction is what separates debt recycling from simply "borrowing to invest" or taking out an equity release: those add new debt on top of what you already owe, while debt recycling converts debt you already have.
From 1 July 2027, negative gearing is restricted for established residential investment properties bought after 7:30pm (AEST) on 12 May 2026 — the night of the 2026 Federal Budget. Investors who buy an existing home or unit after that date can no longer offset rental losses against their salary or wages. Losses can still be claimed, but only against rental income or a future capital gain on that property, with any excess carried forward.
Three groups are exempt from this change: properties already held (or under contract) before budget night, eligible new-build properties that add to housing supply, and every asset class outside residential property — including shares, ETFs, and managed funds.
What this means for debt recycling: a debt recycling strategy built around a diversified share or ETF portfolio isn't affected by the negative gearing restriction at all — it never relied on established-property negative gearing in the first place. For anyone who was planning to negatively gear an established investment property, this is a natural moment to compare that against recycling into shares instead, where the deduction mechanics haven't changed.
One thing that does apply across the board, shares included: from 1 July 2027 the 50% CGT discount is being replaced with cost-base indexation and a 30% minimum tax on gains for assets held more than 12 months. That change affects the tax on your eventual gains, not the deductibility of the loan interest along the way — worth factoring into the numbers, not a reason to avoid the strategy.
| Scenario | Negative gearing from 1 July 2027 |
|---|---|
| Established property held before 12 May 2026 | Unaffected — grandfathered |
| Established property bought after 12 May 2026 | Restricted to rental income / capital gains only |
| Eligible new-build property | Unaffected — still fully deductible against other income |
| Shares, ETFs, managed funds (debt recycling) | Not applicable — was never property negative gearing |

Every debt recycling strategy — regardless of who's running it or which lender is involved — follows the same underlying loop. Here's the five-step cycle at a glance, then the detailed mechanics below it:
Either through extra repayments over time, or equity you've already built through past repayments and property growth. This is the "fuel" for the strategy — the more usable equity you have, the more you can eventually recycle.
Your broker restructures your lending so the investment portion sits in its own loan split with its own account number — completely separate from your home loan. This is what lets you (and the ATO) trace exactly which dollars are for investing and which are for your home.
You draw down the new investment split and send those funds directly to your broker or fund manager. This step matters more than people realise; see redraw vs offset below for why offset withdrawals don't work for this.
Diversified ETFs, listed investment companies, managed funds, direct shares, or an investment property. The asset has to be capable of producing assessable income — that's what supports the tax deduction on the loan used to buy it.
Because the investment loan was used to produce income, the interest is generally tax-deductible under ATO rules. That deduction lowers your taxable income and generates a refund.
Dividends, distributions, rental income, and your tax refund all get redirected back onto your non-deductible home loan — paying it down faster than minimum repayments alone ever would.
As your home loan shrinks and equity grows, you can redraw again and invest further, gradually converting more of your total debt from non-deductible to deductible while your portfolio compounds.

Run My Free Calculator →Debt recycling gets confused with several adjacent strategies. Here's how they actually differ:
| Strategy | What it does | Increases total debt? | Interest deductible? |
|---|---|---|---|
| Pay down mortgage only | Extra repayments reduce your home loan as fast as possible | No | No |
| Invest only (no recycling) | Invest spare cash directly, home loan continues as normal | No | No — no loan is involved |
| Debt recycling | Converts existing home debt into investment debt while investing | No — same total debt throughout | Yes, on the investment portion |
| Negative gearing | Relies on an investment running at a loss to reduce taxable income | Depends on structure | Yes, but the goal is the loss itself |
| Equity release / gearing | Borrows additional funds against equity to invest | Yes | Often yes, but on new, additional debt |
This is the single most misunderstood mechanic in debt recycling, and it's the difference between a compliant strategy and one that quietly falls apart under scrutiny.
An offset account is a separate transaction account linked to your home loan. Money sitting in it reduces the interest charged, but withdrawing it is not borrowing — it's just taking your own cash back. No new debt is created, so there's nothing to make deductible.
A redraw facility lets you pull back extra repayments you've already made. Once you redraw, you are borrowing again — and if that borrowed amount is used to buy income-producing assets, the interest on it can be tax-deductible. This is why debt recycling structures are built around redraw and loan splits, not offset balances.
Tom and Priya own a $950,000 home with a $480,000 mortgage. They have $260,000 in usable equity and want to explore whether recycling makes sense before committing to anything.
They set up a $260,000 investment loan split against their equity, invest it in a diversified share portfolio, and redirect the resulting tax refund back onto their home loan every year, on top of their regular repayments. Modelled over their remaining 30-year loan term at a 37% marginal tax rate:
Their home loan clears 8 years ahead of schedule, and by year 30 they hold a share portfolio funded entirely by equity that was otherwise sitting idle in bricks and mortar. These figures assume steady 8% investment growth and a 3.5% dividend yield — real markets won't move in a straight line, which is exactly why the risk section below matters as much as the upside.

Calculate My Debt Recycling Potential →It isn't. Debt recycling's goal is a faster mortgage payoff and portfolio growth without extra debt. Negative gearing relies on losses to reduce tax. A recycled portfolio can end up negatively geared if it underperforms, but that was never the plan.
Borrowing to invest (gearing) adds new debt. Debt recycling converts debt you already have — your total borrowings don't increase.
It's a legitimate, ATO-recognised structure when set up and documented correctly. The rules aren't secret; they just require accurate tracing and record-keeping.
No investment strategy does. Debt recycling amplifies both gains and losses because it involves borrowing. It rewards patience and discipline over a long horizon — not quick wins.
The most common practical mistake: using redraw or investment-split funds for anything personal. Once purposes are mixed in one account, untangling them for tax purposes is difficult and sometimes impossible.
Just because the equity is technically available doesn't mean the full amount is prudent to redraw. A conservative buffer relative to income and market conditions matters more than maximising the number.
Two principles govern whether the interest on your investment split is deductible:
Dividends and distributions from the portfolio are assessable income in the year received, and franking credits may reduce the tax payable on them. Capital gains or losses on the investments are taxed under normal CGT rules when sold. None of this is a substitute for advice from a registered tax agent who can look at your specific structure — this page is general information, not personal tax advice.
Debt recycling is a small part of what most brokers do. It's the core of what we do — here's who's actually structuring the loan if you work with us.
Founder of Kingfisher Finance Group and the broker behind every debt recycling structure we set up — built around coordinating with each client's accountant and financial planner from the first conversation, not after the loan settles.
Loan splits are matched to the investment plan already in place, and tracing is confirmed before the first dollar is redrawn. With an approval track record clients describe as "we don't have applications declined," Alex is who you want structuring the lending side.
With over 10 years in finance — including years as a senior credit analyst before moving into broking — Jess brings a level of precision to debt recycling structures most brokers don't have. She knows exactly what a lender's credit team will scrutinise, because she used to be that person.
That matters most in debt recycling: a loan split that looks fine but is missing the right paperwork is exactly what causes tracing problems later. Jess's structuring means the loan side is built to hold up, not just to get approved.
Debt recycling rarely fails because the concept is flawed — it fails because the people implementing it aren't coordinated. The strategy touches lending, tax, and investing at the same time, and each of those is a different profession with a different qualification. Getting one of the three wrong doesn't just weaken the strategy, it can unwind the whole thing.
Sets up the loan splits correctly from day one, confirms your lender actually supports redraw and the flexibility the strategy needs, and reviews the structure as rates and equity change. This has to be a broker experienced specifically in debt recycling structures — a generic split loan set up without the strategy in mind is exactly how tracing problems start.
Confirms the purpose test is met, keeps the tracing paper trail defensible, and handles the deduction, dividend, and CGT treatment at tax time. Ideally involved before the first redraw happens, not after — untangling a mixed-purpose loan account retroactively is often impossible.
Selects and manages investments matched to your actual risk tolerance and timeframe — not whatever ETF was trending. Also the person who should be reviewing the strategy against your broader financial plan, insurance, and retirement position, not just the debt recycling loop in isolation.
The sequence matters as much as the personnel. A broker without tax input can build a perfectly compliant-looking loan that still produces a non-compliant deduction. An adviser without broker input can recommend investments funded from the wrong account. An accountant brought in after the fact can find the paper trail impossible to untangle. Engage all three before the first dollar moves — not as an afterthought once something's already gone wrong.
Debt recycling lives or dies on the loan structure. A broker who understands the strategy will:
