What Is Debt Recycling and How Does It Work in Australia?
Debt recycling is a strategy where you gradually replace your home loan debt with investment debt. You pay down your home loan, then re-borrow that amount through a separate loan split and use it to buy income-producing investments. Interest on your home loan generally isn't tax deductible, but interest on money borrowed to invest may be. Over time, more of your debt could become deductible while you build an investment portfolio.
It can be a powerful long-term strategy, but it means borrowing to invest against your home. That comes with real risks, which we cover below.
How does debt recycling work in Australia?
The key rule comes from the ATO: whether loan interest is deductible depends on what the borrowed money is used for, not what the loan is secured against. When you redraw or re-borrow, the ATO treats it as a new borrowing, and its use decides the tax treatment (ATO TR 2000/2).
A typical debt recycling cycle looks like this:
Split your home loan. Your lender sets up a separate loan split (or account) that will be used only for investing.
Pay down your home loan. You put extra money, such as savings, a bonus or investment income, into the non-deductible home loan.
Re-borrow through the investment split. You draw the same amount back out through the separate investment split.
Invest in income-producing assets. You use those funds only to buy investments that produce income, such as shares, ETFs or property.
Repeat. Any investment income and extra savings go back onto the home loan, and the cycle continues.
Your total debt stays about the same. What changes is the mix: the home loan shrinks while the investment debt grows.
A simple example
Sarah has a $600,000 home loan. She saves $20,000 and puts it straight onto her home loan. She then re-borrows $20,000 through a separate investment split and uses it to buy shares.
Before | After one cycle | |
|---|---|---|
Home loan (generally not deductible) | $600,000 | $580,000 |
Investment split (may be deductible) | $0 | $20,000 |
Total debt | $600,000 | $600,000 |
Investments owned | $0 | $20,000 in shares |
Sarah owes the same total, but $20,000 of it now funds investments. If she repeats this each year, her home loan could shrink faster while her portfolio grows.
This example is illustrative only and ignores interest, fees, tax and investment returns. Your outcome will depend on your situation.
What are the risks of debt recycling?
Debt recycling is a form of borrowing to invest, which Moneysmart describes as high risk and a medium to long-term strategy of at least five to ten years. The main risks are:
Investment losses. If your investments fall in value, you still owe the full loan. Borrowing magnifies losses as well as gains.
Your home is on the line. The investment debt is usually secured against your home. If you can't keep up with repayments, you could lose your home.
Interest rate rises. Higher rates increase the cost of the investment debt, which can eat into or wipe out any benefit.
Income changes. Job loss, illness or a drop in income could make repayments harder. The strategy relies on steady cash flow.
Mixing funds can cost you the deduction. If money from the investment split is used for anything private, even briefly, the interest on that portion may no longer be deductible. This is often called "contamination", and it's one of the most common mistakes.
The wrong loan setup. Not every home loan or lender supports a clean split structure. Using a single loan with redraw for both purposes can make records messy and deductions harder to prove.
Short time frames. If you plan to sell your home or need the money soon, the strategy may not have time to work.
Borrowing to invest only makes sense if your after-tax return is greater than all the costs of the loan and the investment.
Who might debt recycling suit?
Debt recycling is generally considered by homeowners who:
have built up equity in their home
have a stable income and spare cash flow each month
are comfortable with investment risk and market ups and downs
plan to stay in their home and invest for the long term
It's not suitable for everyone. Because it involves tax and investment decisions, speak with an accountant or licensed financial adviser before you start.
Where a mortgage broker fits
A broker's role is the lending side: making sure your loan is structured correctly from day one. That includes finding a lender whose products support separate loan splits, setting up the right accounts, and checking the structure suits your borrowing capacity. Getting the setup wrong is where many debt recycling plans go off track, so this part matters.
Frequently Asked Questions
Is debt recycling legal in Australia?
Yes. Debt recycling is a way of structuring loans, and the ATO's rules on interest deductibility apply to it like any other borrowing. Interest may be deductible when borrowed funds are used to produce income, so correct setup and record-keeping are essential.
Does debt recycling increase my debt?
Not usually. Your total debt stays about the same. The strategy changes how much of that debt is linked to your home versus your investments.
Can I debt recycle using an offset account?
Withdrawing your own savings from an offset account is not new borrowing, so it doesn't create deductible debt. Debt recycling generally relies on re-borrowing through a separate loan split. Ask your accountant how this applies to you.
What can I invest in with debt recycling?
The funds generally need to go into income-producing investments, such as dividend-paying shares, ETFs or an investment property. Speak with a licensed financial adviser about what suits you.
Is debt recycling the same as negative gearing?
No. Negative gearing is when investment costs exceed the income an investment produces. Debt recycling is about restructuring existing home loan debt into investment debt over time. The two can overlap, but they are different strategies.
Thinking about debt recycling?
Before you start, make sure your home loan is set up to support it. Book a chat with Mario to check whether your current loan structure works for debt recycling, and what your lending options could look like.
