In debt recycling the investment you choose is not just a return question — it is a deductibility question. The borrowed money must be used to acquire assets that produce, or can reasonably be expected to produce, assessable income. Get this wrong and the ATO may deny the interest deduction entirely, collapsing the strategy's core benefit.
The deductibility lens: income first, growth second
Under section 8-1 of the ITAA 1997, interest is deductible when borrowed funds are used for income-producing purposes. The ATO looks at the use of the money, not which asset secures the loan. That means a pure-growth stock that pays zero dividends and has no reasonable expectation of producing income in the foreseeable future can put the deduction at risk.
In practice, this steers most debt recyclers toward dividend-paying shares, broad index ETFs that make regular distributions, managed funds, and listed investment companies (LICs). You can still own growth-tilted holdings inside the mix — the portfolio as a whole just needs an income-producing character.
Asset types at a glance
Franked Australian shares
Direct holdings in ASX-listed companies that pay fully franked dividends are a natural fit. Franking credits represent the 30% company tax already paid on the profit behind each dividend, and they flow through to you as a tax offset — or even a cash refund if your credits exceed your tax bill.
A $700 fully franked dividend grosses up to $1,000. You declare the full $1,000 but receive a $300 franking credit against your personal tax. For a debt recycler on a 39% marginal rate (including the 2% Medicare Levy), that credit turns the effective tax on the dividend income well below the headline rate.
Watch out for: concentration risk. Loading up on a handful of high-yield bank or mining stocks to chase franking can leave you dangerously exposed to a single sector. Remember the 45-day holding rule, too — you must hold shares "at risk" for at least 45 days around the ex-dividend date to claim franking credits above $5,000 in a financial year.
Broad index ETFs — Australian and global
Exchange-traded funds tracking the ASX 200 or a global index offer instant diversification and low management expense ratios (MERs), typically 0.03% to 0.25% for mainstream options. Australian-market ETFs pay quarterly or semi-annual distributions, usually partly franked. Global ETFs distribute income too, though franking is generally absent because the underlying companies pay tax overseas, not Australian company tax.
The appeal: you spread your capital across hundreds or thousands of companies, reduce single-stock blow-up risk, and keep fees low — which matters even more under leverage (see below).
Actively managed funds
Managed funds pool investors' money and have a fund manager select securities. They pay distributions (income and sometimes realised capital gains) at least annually. Distributions are assessable income, supporting the deductibility requirement.
Be aware: active funds carry higher MERs — often 0.70% to 1.50% or more — and can distribute capital gains at inconvenient times, triggering a tax bill even when the fund's unit price has fallen. Under leverage, those higher fees and unpredictable capital-gains distributions are amplified.
Listed investment companies (LICs)
LICs are closed-ended investment vehicles listed on the ASX. Many long-established LICs pay fully franked dividends smoothed across years, which suits the steady-income requirement of debt recycling. Because they are closed-ended, the manager is not forced to sell holdings to meet redemptions.
The catch: LICs can trade at a premium or discount to their net tangible assets (NTA). Buying at a significant premium means you are overpaying for the underlying portfolio, and a discount that widens after purchase erodes your return even if the investments inside perform well.
What to be cautious about
- Pure-growth, no-income assets. A company that has never paid a dividend and reinvests all earnings may not satisfy the income-producing expectation. If challenged, the ATO could disallow the interest deduction on the borrowing used to buy it.
- Speculative assets and cryptocurrency. Whether crypto produces assessable income is murky at best. Staking rewards can generate income, but many holdings produce nothing. Speculative stocks with no revenue face the same issue. The safer position is to keep borrowed debt-recycling funds in assets with a clear income track record.
- High-fee products. A 1.5% MER on a leveraged portfolio with a 6% borrowing cost eats into the narrow gap between your after-tax interest cost and your return. Fees are certain; returns are not.
Rule of thumb: if the asset you are considering has no history of paying distributions and no reasonable prospect of doing so, it probably should not be funded with debt-recycling borrowings. Keep it in a separate, non-borrowed allocation instead.
Franking versus global diversification
It is tempting to load a debt-recycling portfolio entirely with high-yielding, fully franked Australian shares to maximise franking credits. The maths looks compelling on paper: a 39% marginal-rate taxpayer effectively receives a 30-cent head start on every dollar of franked dividends.
But Australia represents roughly 2% of global equity market capitalisation. Skewing everything toward the ASX concentrates your portfolio in financials, materials and a handful of other sectors. A global allocation sacrifices franking on the international portion but gains exposure to technology, healthcare and other sectors under-represented on the ASX — and, historically, similar or higher total returns over long periods.
Most advisers suggest a blend: enough Australian exposure to capture meaningful franking benefits, combined with global diversification to manage sector and country risk. The right split depends on your marginal tax rate, risk tolerance and time horizon — there is no universal answer.
Fees matter more under leverage
When you borrow to invest, fees eat into the spread between your borrowing cost and your return. The table below shows the effect of different MERs on a hypothetical $200,000 debt-recycling portfolio, assuming a 6% gross return and a 6% interest rate at a 39% marginal rate (after-tax borrowing cost of 3.66%).
| MER | Annual fee drag | Net return after fees | Spread over after-tax interest |
|---|---|---|---|
| 0.04% | $80 | 5.96% | 2.30% |
| 0.25% | $500 | 5.75% | 2.09% |
| 0.70% | $1,400 | 5.30% | 1.64% |
| 1.50% | $3,000 | 4.50% | 0.84% |
At a 1.50% MER the spread shrinks to under one percentage point — barely enough to justify the leverage risk, especially in a bad year. Low-cost index products preserve the widest gap between borrowing cost and return.
Distribution timing and DRPs
Many investors default to dividend reinvestment plans (DRPs), which automatically use distributions to buy more units. In a debt-recycling context, that habit deserves a rethink.
The primary goal of the strategy is to pay down non-deductible debt as fast as possible. Directing distributions — and any franking-credit refunds — to the non-deductible home-loan split accelerates that paydown. Each dollar that hits the home loan is a dollar you can recycle into the deductible investment split, continuing the loop.
Auto-reinvesting via a DRP does grow your investment balance faster, but it leaves your non-deductible loan untouched for longer. That means you are paying non-deductible interest for longer — the exact cost the strategy is designed to eliminate.
The trade-off is straightforward: DRPs maximise portfolio growth; directing distributions to the home loan maximises the speed of debt conversion. For most debt recyclers, paying down the non-deductible side first is the higher-priority move, but your circumstances may differ.
An illustrative core portfolio
The following is a simplified example of how a debt-recycling portfolio might be structured. It is not a recommendation — just an illustration of the principles above applied in rough proportions.
- 40% Australian equities ETF — broad ASX 200 exposure, partly franked distributions, low MER.
- 40% Global equities ETF — developed-world large- and mid-cap exposure, unfranked distributions, low MER.
- 20% Australian equity income ETF or LIC — tilted toward higher-yielding, fully franked companies to boost franking credits without concentrating in individual stocks.
This blend aims for income generation across the whole portfolio, meaningful franking, broad diversification, and fees well under 0.20% on a weighted basis. Your actual allocation should reflect your risk tolerance, existing super holdings, time horizon and professional advice.
Key takeaways
- The investment must produce — or be reasonably expected to produce — assessable income, or the interest deduction is at risk.
- Franked Australian shares boost after-tax returns, but over-concentration in a few high-yield stocks creates sector risk.
- Low-fee index ETFs preserve the widest spread between after-tax borrowing cost and investment return.
- Directing distributions to the non-deductible home loan usually beats auto-reinvesting via a DRP because it accelerates the debt conversion loop.
- Balance franking benefits with global diversification — Australia is roughly 2% of global equity markets.

Can I use debt-recycling funds to buy property instead of shares?
In principle, yes — if the property produces rental income the interest can be deductible. In practice, direct property is harder to buy in small, recurring parcels the way shares or ETFs are, making the recycling loop cumbersome. Most debt recyclers use listed securities for this reason.
What if my investments drop in value — do I lose the deduction?
No. The deduction is based on the use of the borrowed funds at the time of borrowing, not the current market value of the investment. As long as the original funds were used to acquire income-producing assets, the interest remains deductible even if the portfolio falls.
Should I avoid growth stocks entirely?
Not necessarily. A portfolio can include growth-oriented holdings as long as the overall mix has a genuine income-producing character. The concern arises when borrowed funds are used exclusively for assets with no income history or expectation — that is where the deductibility risk sits.
