By the time most people search for a debt recycling strategy, they already know that it works. What they cannot find is a straight answer on how much they can save, and whether thteir existing loan can run it at all.
Most Australian content on debt recycling strategy is written by accountants and financial advisers. It explains the tax logic well, then stops at the words “set up a separate split,” as though a split is a formality your bank will arrange on request. It is not. In practice, the loan structure is where this strategy succeeds or quietly falls apart, and it is the part almost nobody writes about.
With over 20 years of experience and more than $500M settled lending, mostly for investors and high-income professionals, this is a pattern we see often. The tax concept is rarely the problem. The common problem is a lender that charges a fee for every new sub-account, a fixed rate that blocks the re-borrow entirely, or a redraw sitting where an offset should be.
In this article, we’ll walk you through a worked example with real numbers, then the loan structure behind it. How splits are set up, what they cost, which lender rules to check before you commit, and the structural mistakes that cost people their deduction.
(New to the term? Start with our explainer on what debt recycling is and whether it is worth it.)
What a Debt Recycling Strategy Looks Like in Real Numbers
Here is a structure we set up for a high-income client.
They had an $800,000 home loan and had been paying it down hard, taking the balance owing to $200,000. That left $600,000 sitting in the loan as available redraw. Rather than leave it there, they drew the $600,000 back out and used it to buy shares.
The important part is what happened to the character of that debt. The money was still secured against their principal place of residence, but because of what it funded, the $600,000 became deductible debt. The security did not decide the tax treatment. The use of the funds did.
So what does that actually cost?
Let us run it at 6.25 per cent, which sits in the middle of the average variable rates being reported in August 2026. Assume the client is on the top marginal rate of 47 per cent, made up of 45 per cent tax plus the 2 per cent Medicare levy.
The interest on the split is $600,000 multiplied by 6.25 per cent, which comes to $37,500 for the year.
The deduction is worth $37,500 multiplied by 47 per cent, which is roughly $17,600 back at tax time.
The real cost is what is left, so $37,500 less $17,600, which is about $19,900.
Divide that back into the $600,000 and the effective rate lands at roughly 3.3 per cent.
Two things worth saying about those figures. The arithmetic works the same at $60,000 as it does at $600,000, so if your available redraw is smaller, only the amounts change. And this is rarely a single event. Most clients repeat the cycle every year or two as they pay the loan back down, which is why the structure matters far more than the first transaction.
That is the number that matters, and it is not the number most articles quote. Debt recycling is not a tax refund. Nobody hands you $17,600. What changes is your after-tax cost of capital, which in this case falls by nearly half. The strategy only makes sense if you expect the investment to return more than that reduced cost over the time you intend to hold it, and that is a question for your financial adviser rather than your broker.
Illustrative only. Rate based on average variable rates reported in August 2026 with the RBA cash rate at 4.35 per cent. Your rate, tax position and outcome will differ.
How a Redraw Deposit Avoids Cross Securitisation
The real cost is what is left, so $37,500 less $17,600, which is about $19,900.
Divide that back into the $600,000 and the effective rate lands at roughly 3.3 per cent.
The bigger win here was on the lending side, and it is the part nobody writes about. Because the deposit came out as cash, the new lender did not need to take a mortgage over the family home as well. That meant the two properties were never cross secured.
Cross securitisation is when one lender holds both of your properties as security for both loans. It seems harmless when you sign. It stops seeming harmless the day you want to sell one property, refinance one loan, or chase a better rate on just one of them. Every one of those moves now needs that lender’s sign off, and often a fresh valuation of both properties.
Drawing the deposit as cash avoided all of that. The client took the new purchase to the sharpest lender available and left the family home standing on its own. That is the difference between a deposit you have borrowed as cash and a deposit the lender must carve out of your home’s equity.
Offset vs Redraw? Which One Do You Actually Need
Almost every home loan comes with an offset account, a redraw facility, or both. Most borrowers treat them as two versions of the same thing, since either one lets you park spare money against the loan and pull it back out later.
For debt recycling, they are not the same thing at all. One of them creates a tax deduction and the other cannot. Choosing wrong is the most common structural mistake we see.
A redraw creates new borrowing. When you make extra repayments, your loan balance goes down. When you draw that money back out, you are borrowing it again, and the interest on it is treated as fresh debt. What you spend it on then decides whether that interest is deductible. This is exactly what our earlier client did. They paid the loan down to $200,000, redrew $600,000 to buy shares, and because those funds went into an investment, the interest became deductible.
An offset does not. The money in an offset is your own cash. It sits alongside the loan and reduces the interest you are charged, but it never reduces the loan balance itself. So when you take that cash out, nothing about the loan has changed. You have not borrowed anything, which means there is no interest to deduct.
So which one do you need? It usually comes down to a question most borrowers are never asked. Is this your forever home?
If it is, and you plan to recycle into shares or an investment property deposit, a redraw through a dedicated split is the mechanism that makes it work.
If it is not, and this house will eventually be rented out, an offset is usually the better structure. Here is why. Paying the loan down through redraw permanently shrinks the balance. When the property later becomes an investment, only that smaller balance is deductible. Put the same money in an offset instead and the loan balance stays where it is, so the day the property switches to investment use, the full amount is working for you.
We had a client this month on a no-frills loan. Cheapest rate on the market, no offset attached. Once we worked through what they actually planned to do with the property, it was clear the cheap rate was costing them the structure they needed. They changed loans.
What Your Loan Must Let You Do
The strategy only works if your loan can actually perform the re-borrow. Here are the three factors that decide whether it can.
First, you need a separate split. The re-borrowed money must sit in its own account and never mix with anything else. That means one personal transaction into an investment split, and you have already contaminated it. From that point on, you are separating deductible interest from non-deductible interest every year for as long as you hold the loan.
Most lenders will set up a split if you ask. What varies is what they charge. Some want around $400 to restructure. Others do it for nothing. No lender advertises this, and if you repeat the strategy every year or two, the difference adds up.
Now, the biggest obstacle is the fixed rate. If your loan is fixed, you may not be able to run this at all. Here is what four lenders currently allow:
Lender | Fee-free prepayment cap on a fixed loan | Redraw during the fixed term |
Westpac | $30,000 cumulative | Available on prepayments; exceeding the cap can trigger a break cost plus an administration fee |
St.George | $30,000 | Only on extra repayments made during the current fixed term, up to the cap |
BankSA | $30,000 | Only on extra repayments made during the current fixed term, up to the cap |
Pepper Money | Not Applicable | Not available during the fixed period |
Fixing the whole loan also removes your ability to link a 100 per cent offset account with St.George and BankSA. So, a borrower who has fixed the lot and then wants to recycle $200,000 has two options. Wait until the term ends, or refinance out of it and wear the break cost.
Lender terms noted were current as of August 2026 and should be confirmed before acting.
The rest depends on your lender. How many splits you get, whether each one costs you, how quickly they are set up, and whether the split is priced at owner-occupier or investment rates. None of this is published anywhere. These are the questions we work through against our panel before anyone commits to a structure.
One more thing determines whether this is workable, and it sits entirely outside your current loan. Once part of your borrowing is investment debt, the next application is assessed differently, and borrowing power can look very different to what you expect. Here is what changes and why.
The Debt Recycling Mistakes We See Most Often
The most expensive errors have nothing to do with the tax rules. Here are the debt recycling strategy mistakes we see most often.
First, paying the home off and then upgrading. A client owned a house worth $800,000 and wanted to buy a $1.3M home. They were determined to keep the first one and rent it out. Since the original loan was already paid down, they had to borrow the full $1.3M plus costs against the new home, and none of that interest is deductible. Had they kept a loan against the first property at around 80 per cent of its value, that money could have gone into the new purchase as cash, and the deduction would have sat against the property earning the rent. We see this constantly.
Second, moving into your investment property. One client called us recently after moving out of their home and into a property they had rented out for years. All their debt sits against that second property, which is now where they live, while the house they left behind earns modest rent and carries almost no loan. The result is that none of the debt is deductible any more. Once the debt is against the wrong property, there is no way to move it, and the only real fix is to sell.
Third, assuming the strategy suits you. The debt recycling strategy only works if you genuinely save, and if you are willing to borrow against your home again once it is paid down. It also assumes you can live with the investment falling in value while the loan sits at the same balance regardless. Plenty of people want nothing more than to own their house outright and never mortgage it again. That is a perfectly good goal. It is just not compatible with debt recycling, and we would rather say so at the first meeting than build a structure nobody wants to use.
The most expensive errors have nothing to do with the tax rules. Three come up again and again, and the first two are usually only spotted once it is too late to fix them.
Is Your Loan Structured for a Debt Recycling Strategy?
If you have read this far, the tax logic is probably already clear to you. What is far less clear is whether your own loan can carry the strategy, and that is the question worth answering before anything else.
Start with what you already have. Is the loan fixed or variable. Does it have an offset, a redraw, or both. What does your lender charge to create a split, and how many will they give you. Is this house your forever home, or will it become an investment one day. Those answers decide the structure, and the structure decides whether the deduction survives.
This is the part a broker handles. Your accountant confirms the tax treatment. We work out what your lender will actually allow, what a split will cost you, and whether another lender on our panel would serve the strategy better. After 20 years and more than $500M settled, mostly for investors and high income professionals, we have seen how these structures hold up and where they fall over. Eakins Finance provides credit advice only, so we work alongside your accountant and financial adviser rather than in place of them.

Frequently Asked Questions
How much does a debt recycling strategy actually save?
It does not hand you money. It lowers what your borrowing costs. In our worked example, interest of $37,500 with a deduction worth $17,600 brought the real cost down to $19,900, an effective rate of about 3.3 per cent instead of 6.25 per cent.
Is there a debt recycling calculator I can trust?
Most calculators only model the tax side, so they show a saving without asking whether your loan can perform the re-borrow. A result that assumes free splits and a variable rate is meaningless if your loan is fixed or your lender charges for every sub-account.
Can I use my offset account instead of a redraw?
No. Money in an offset is your own cash, so withdrawing it is not new borrowing and there is nothing to deduct. Redraw is what creates the borrowing. Offset is the better structure when the home will later become an investment property.
Can I do this if my home loan is fixed?
Often not. Several lenders cap fee-free prepayments on a fixed loan at around $30,000, and some do not allow redraw during the fixed term at all. You may need to wait out the term or refinance and wear the break cost.
What happens if I use the investment split for something personal?
The split is contaminated. From then on, you are apportioning deductible and non-deductible interest for the life of the loan, which is why the split should be used once, for one purpose, and never touched again.
