On a top marginal rate, every dollar of investment loan interest is worth more back to you. We structure the lending so that value is captured cleanly, year after year.
Home › Debt recycling loans › High-income earners
Debt recycling gradually converts the non-deductible debt on your home into deductible debt used to hold income-producing investments. The mechanics are the same for everyone. What differs is how much the deduction is actually worth, and that depends almost entirely on your marginal tax rate.
A tax deduction reduces your taxable income, so its cash value is set by the rate that applies to your top dollar of earnings. A deduction is worth far more to someone paying tax at the highest bracket than to someone in a lower one. That is the whole reason this strategy tends to suit high-income professionals more than most: you are typically the person for whom deductible investment interest returns the most.
For a PAYG professional on a high salary, the arithmetic is generally straightforward. You already hold equity in your home. You already pay tax at a high rate. Debt recycling aims to put both of those facts to work at once, without increasing your total borrowings.
The core idea in one line. Same investment interest, same loan balance, but the higher your marginal rate, the larger the share of that interest the deduction hands back to you at tax time.
The table below is illustrative only. It shows the approximate value of $10,000 of deductible investment loan interest at different marginal rates, using current-law rates including the 2% Medicare levy. Your actual position depends on your income, offsets and circumstances, so treat these as round examples rather than a calculation of your outcome.
| Marginal rate (incl. Medicare levy) | Value of $10,000 deductible interest | Effective after-tax cost of that interest |
|---|---|---|
| 32% | $3,200 back | $6,800 |
| 39% | $3,900 back | $6,100 |
| 47% (top rate) | $4,700 back | $5,300 |
The pattern is the point. At the top rate, close to half of the interest cost on the deductible split is effectively offset by the deduction, which lowers the return your investments need to earn before the strategy gets ahead. Figures are hypothetical, rounded, and assume the interest is genuinely deductible under the ATO purpose test. See is debt recycling tax-deductible for how that test works.
Hypothetical only, stated assumptions. Take a $40,000 deductible split at an assumed 6% interest rate. That is roughly $2,400 of interest in a year. For someone at the 47% top rate, the deduction is worth about $1,128 back at tax time, which brings the after-tax cost of holding that investment debt down to around $1,272. The investments bought with that split are then expected to produce income and growth over time, while the income and the refund are redirected to pay down the non-deductible home loan faster.
These numbers are illustrative and rounded. They are not a quote, a forecast or a promise of any result, and they ignore the many variables that apply to a real situation. We do not recommend specific investments: your financial adviser recommends the assets, and we structure the loan around that plan.

These do not stop debt recycling from working, but they are part of the picture your accountant will weigh when comparing strategies. In some cases the flexibility of debt recycling, where the investments sit outside super and remain accessible, is part of why high earners consider it alongside, not instead of, their super contributions.
How the interaction plays out is specific to your circumstances, so this is a conversation for your registered tax agent, not a general rule. We handle the lending; your tax adviser confirms what applies to you.
A high marginal rate makes the deduction valuable, but only if the interest is deductible in the first place. That comes down to how the loan is built. If the deductible and non-deductible borrowings are ever mixed in one account, the deduction can be compromised, and at your tax rate that is an expensive mistake to make.
The way we prevent it is deliberately plain: a separate, clean investment split with its own account number, funds drawn by redraw rather than through an offset, and the money traced straight to the investment before a single dollar touches anything private. Done properly, the top-rate deduction you are relying on holds up if it is ever examined. You can read how we build it on the loan structure page.
We check what equity is available and how it fits your broader plan, alongside your adviser.
We arrange a clean, separate deductible split, refinancing where your current loan cannot split cleanly.
You invest the split into the income assets your adviser recommends, then channel the income and tax refund back to the home loan.
The tax saving is a tailwind, not the engine. The strategy works over years, through market ups and downs, and it depends on you staying the course and continuing to redirect income and refunds to the non-deductible loan. High income helps because it usually supports the cashflow to keep recycling in tranches, but a long horizon and steady behaviour do the heavy lifting. Whether it clears the hurdle for you is covered in is debt recycling worth it.
If your income comes from self-employment, a business or a trust rather than a salary, the evidencing and structuring differ, and that is covered on our self-employed and business owners page.
