Let's get started with our review of the week. This review is from Martin Brown. He writes, "Very impressed with level of service and professionalism I received from Aevum, they made a daunting task extremely easy for me. I highly recommend them." Thanks for the amazing review, Martin. And we are back. Today we are talking about a strategy called debt recycling. This is one of the most requested topics we get. Everyone wants to know: how can I make the interest on my home loan tax-deductible? Because right now, for most Australians, that mortgage is just a black hole. You pay interest, the bank keeps it, and the ATO gives you nothing. That is what we call bad debt. It's debt on a personal asset that doesn't generate income. But what if you could turn that bad debt into good debt? Debt that is tax-deductible just like a business loan. That is exactly what debt recycling does. Now before we dive into the mechanics, we need to make a very important disclaimer. Aevum Accounting provides tax advice; we can tell you how to structure the loans so the interest is deductible. But we do not provide financial advice. That is a crucial distinction. We cannot tell you which shares to buy or which property to invest in. We can explain the tax consequences of the strategy, but for the investment selection and risk assessment, you must speak to a qualified financial planner. Okay, disclaimer noted. So let's start with the definition. What is the difference between debt recycling and just borrowing to invest? Great question. Borrowing to invest—gearing—usually means taking out a new loan on top of your existing mortgage. Your total debt goes up, your risk goes up. Debt recycling is different. You are taking your existing debt level and simply changing its color. You pay down the bad debt and immediately redraw it as good debt. Your total debt stays roughly the same, but the tax-deductibility changes. So walk us through the cycle. How does the wash actually work? It's a four-step process. Step one: save. You save up a lump sum of cash, let's say $10,000. Step two: pay down. You pay that $10,000 directly into your home loan variable account. This reduces your non-deductible debt. Step three: split and redraw. You ask the bank to create a separate loan split for that $10,000. You then borrow that money back out. Step four: invest. You use that borrowed $10,000 to buy an income-producing asset like shares or ETFs. And because the purpose of that new $10,000 loan was to buy investments, the interest is now tax-deductible? Exactly. You have recycled that $10,000. It used to be a home loan; now it's an investment loan. And then you take the dividends from the shares and the tax refund you get from the interest deduction and you use that to pay down the home loan again. That's the snowball effect. Every year your home loan gets smaller, every year your investment loan gets bigger. Eventually, your home loan hits zero and your entire debt is tax-deductible. It sounds brilliant, but Ben De Rosa sees people mess this up all the time. What is the biggest trap? The biggest trap is the mixed-purpose loan, or as Ben calls it, the Lazy Larry approach. This happens when people have a $500,000 home loan, they pay down $50,000 and then they just redraw it from the same loan account number to buy shares. Why is that a problem? Because now you have a contaminated loan. You have one account with $450,000 of private debt and $50,000 of investment debt mixed together like a fruit smoothie. You can't unmix it. When you make a repayment next month, which part did you pay off? You'd want to say you paid off the private part first. Of course you would, but the ATO says no way. If you have a mixed loan, every single repayment must be apportioned. So if you pay $2,000 off the loan, 90% of it goes to the house and 10% goes to the investment. This is a disaster because you are accidentally paying off your deductible debt, which you don't want to do. So you lose the efficiency. That is why Ben insists on loan splits. Exactly. If you want to recycle $50,000, you need a separate loan account number for that $50,000. It must be clean. Loan A: $450,000, home private. Loan B: $50,000, shares deductible. That way every dollar you put into Loan A kills the bad debt, while Loan B stays interest-only to maximize the deduction. Another trap Ben mentioned is the offset account mistake. Oh, this is a classic. People think, "I have $50,000 in my offset account, I'll just transfer that to my CommSec account and buy shares." Stop. Do not do that. Why? It's the same money. No, it's not. Money in an offset account is your savings. You aren't borrowing it; you are just spending your own cash. To make the interest deductible, there must be a borrowing event. You must take the money out of the offset, pay it into the loan so the loan balance goes down, and then redraw it back out so the loan balance goes up. It feels like a magic trick, moving money in and out. It feels like it, but legally it is critical. The redraw creates the new borrowing purpose. The transfer from offset is just spending cash. If you just spend cash, you get zero tax deduction on the interest. That is a subtle but expensive detail. Now let's talk about Part 4A. We can't have a tax podcast without mentioning the anti-avoidance rules. Does the ATO hate debt recycling? The ATO doesn't like schemes. If the only reason you are doing this is to get a tax benefit, they can apply Part 4A and cancel your tax deduction. However, if your dominant purpose is to build wealth and generate income, then it is generally acceptable. So you need to actually invest in something that makes money. Correct. You can't invest in a Ponzi scheme or a non-income producing asset like gold or crypto, unless there's a clear income stream, which is rare. You generally invest in shares or ETFs that pay dividends. The expectation of income—dividends—justifies the deduction of the expense: interest. So buying a holiday home that you never rent out? No deduction. That's private use. Buying a plot of vacant land that sits there for ten years? Risk of no deduction because it generates no income. Buying a diversified portfolio of ASX 200 shares? Generally safe. Let's look at the timeline. People think this is a get-rich-quick scheme. It is definitely not. It is a get-rich-slow scheme. Year one: you might only recycle $20,000. The tax benefit might only be $500. It feels small. You might wonder why you bothered with the paperwork. Year five: maybe you have recycled $150,000. Now your tax refund is $4,000 a year, and your shares have hopefully grown in value. Year ten: maybe your house is paid off entirely. You now own a debt-free home and a $500,000 share portfolio. And that is the goal. To own your home debt-free while holding a massive portfolio of investments. Exactly. And the best part: if you ever sell the shares to pay off the investment loan, you just pay capital gains tax on the profit. But you've spent ten years claiming tax deductions along the way. Let's talk about property versus shares. Because the strategy changes slightly depending on what you buy. Yes. Property is usually the big chunk approach. You create one big split, say $100,000, and use it as a deposit for an investment property. It's clean, it's simple, it happens once. But shares are usually a drip feed. Correct. Most people save $5,000 a month and want to invest it. The problem is, banks hate creating a new loan split every single month. They won't make you twelve new loan accounts a year. So for share investors, you often do it in batches. You might save up $20,000—four months of savings—and then do one recycle transaction. It's less admin. What about the risks? We need to be balanced here. The biggest risk is the market. If you borrow $100,000 against your house to buy shares and the share market crashes by 50%, you still owe the bank $100,000. Your house is on the line. That is why we say, see a financial planner. Do not leverage your family home unless you understand the risks of a margin call or a market crash. And interest rates. Another huge risk. If rates go up, your good debt becomes more expensive. You need to make sure the dividends from your shares can help cover that interest, or you need to have the cash flow to service it. So if a listener wants to start this, what is the checklist? Step one: talk to a mortgage broker who understands loan splits. Not all bankers understand this strategy. You need a structure that allows for multiple splits without huge fees. Step two: talk to a financial planner to design the investment portfolio. Step three: talk to Ben De Rosa at Aevum Accounting to set up the tax structure. He will make sure you don't fall into the mixed-purpose trap or the Part 4A trap. It's a team sport. You need the broker, the planner, and the accountant. Absolutely. Don't try to DIY this on a spreadsheet. The stakes—your family home—are too high. Well, that was a deep dive. I think we are onto a winner provided we stay disciplined. Discipline is key. You have to actually use the tax refunds to pay down the debt, not to buy a jet ski. No jet skis. Got it. Well, that brings us to the end of this episode.
