I'm Sam, a finance broker based in Melbourne. This guide explains debt recycling — a strategy some people use to gradually turn part of a home loan into investment debt — without the jargon.

This guide won't make you a financial adviser or a tax agent, and it's not meant to. It's meant to give you the lay of the land, so when you sit down with the right professionals, you know what to ask and what to look out for.

In 30 Seconds

Debt recycling gradually swaps non-deductible home-loan debt for investment debt, using equity you already have. Done properly, the interest on the investment portion may become tax deductible over time. Done without the right structure — or without genuine appetite for investment risk — it can just as easily go wrong. Below: how it works, a worked example, what may qualify, and the risks, before you talk to anyone.

Important

Borrowing to invest can increase gains, but it can also increase losses. You still owe the loan even if the investment falls. When your home is used as security, your home may be at risk.

Big Disclaimer

This guide is general education only. It does not know your income, debts, goals, family situation, tax position or ability to handle losses. It is not a recommendation to borrow or invest.

Before Doing Anything, Speak With the Right People

01
Investment Strategy
Speak with a licensed financial adviser or financial planner. They should decide whether borrowing to invest suits your goals and risk level.
02
Tax Strategy
Speak with a registered tax agent. They should confirm whether the interest may be deductible and how the investment should be owned and recorded.
03
Loan Structure
Speak with a mortgage broker or credit adviser. They can explain loan splits, repayments, lender rules and borrowing capacity.
04
Legal Structures
Speak with a lawyer when companies, trusts, partnerships, guarantees or asset-protection structures are involved.
Remember

A tax deduction does not make an expense free. It only reduces part of the cost. Never buy a bad investment just to get a tax deduction.

Debt Recycling in One Minute

Changing the purpose of debt — not making debt disappear. Most home-loan interest is private and is usually not tax deductible. Interest on money borrowed for an income-producing investment may be deductible when the loan is correctly used and recorded.

The Easy Way to Remember It

The ATO follows the money. What did the borrowed money actually buy? The house used as security does not, by itself, decide the tax result.

The Sequence
Five steps, roughly in this order

Debt recycling may keep total debt similar at first. The goal is to replace some private debt with investment debt over time.

A Simple $100,000 Example

Two ways a person might invest money that is sitting in an offset account. Meet Alex. Alex has $100,000 in an offset account and wants to invest for the long term.

Path A: Take Cash From the Offset

Alex removes the $100,000 and invests it. The offset becomes smaller, so the home loan is charged more interest. That extra home-loan interest usually stays private and non-deductible.

Path B: Use a Clean Investment Split

After getting financial and tax advice, Alex uses a properly separated investment loan. The borrowed money goes directly to the investment. The interest may be deductible.

Very Important

Moving money in the wrong order, mixing private spending into the investment loan, or using the wrong account can damage the tax result. Get the structure checked before moving any money.

What Has Changed?

One Sentence Summary

Debt recycling tries to make the same investment while using a cleaner, income-producing loan purpose.

The 30-Year Maths Example

The difference comes from investing the tax savings and allowing them to grow. The example ignores tax on dividends and capital gains, fees, inflation, changing rates and market falls.

What Investments May Qualify?

There is no automatic master list — the key test is whether the borrowed money is used to earn taxable income.

The General Rule

Interest may be deductible when borrowed money is used to buy or support an investment that earns, or is reasonably expected to earn, assessable income. Only the interest may be deductible — not the amount borrowed.

01
Shares
Australian or overseas shares where it is reasonable to expect dividends or other taxable income.
02
ETFs, LICs and Managed Funds
Funds and trusts that are expected to pay taxable distributions.
03
Interest-Paying Investments
Bonds, notes, term deposits, private-credit funds and similar investments that pay taxable interest.
04
Rental Property
Residential or commercial property that earns rent. Residential-property tax rules are changing, so tax advice is essential.
05
Businesses and Business Assets
A genuine income-producing business, equipment, stock, machinery or other assets used to earn business income.
06
Trust or Partnership Interests
Units or interests expected to pay taxable distributions or business income.
07
Farming and Primary Production
Income-producing farmland, livestock, equipment or other genuine primary-production assets.
08
Royalty-Producing Assets
Some intellectual property or licences that produce taxable royalties.
09
Foreign Investments
Overseas shares, funds, bonds, businesses or rental property that produce taxable income.
10
Income-Producing Loans
In some cases, lending money on commercial terms to earn taxable interest. Related-party loans need specialist advice.

This is a list of common examples, not a guarantee. The exact facts, ownership and records decide the tax outcome.

Special Advice and Common No-Go Areas

Some investments have difficult or uncertain tax rules. Get specialist advice before borrowing for any of these:

01
Start-Ups or Growth Shares
A company may not pay income for years. The expected-income test can become important.
02
Crypto and Staking
The result depends on the activity, purpose, records and type of income. Do not assume the interest is deductible.
03
Gold, Art and Collectibles
Assets held only for price growth may not have a clear income-producing purpose.
04
Vacant Land
Holding-cost deductions can be restricted and special exceptions may apply.
05
Options, Derivatives and Trading
Investor, trader and business rules can produce very different tax results.
06
Your Own Company or Trust
Loans, shares and distributions between related parties need proper documents and may trigger extra rules.
07
Mixed-Use Assets
If something is partly private and partly income-producing, the interest usually needs to be split.
08
Super Contributions
Personal super contributions have separate deduction rules. Borrowing interest should not be assumed deductible.

Borrowing for These Private Uses Is Usually Not Deductible

Do Not Guess

Two people can buy the same asset and receive different tax outcomes because their purpose, ownership, loan use and records are different.

Keep the Loan Clean

Good records and separate accounts are a major part of the strategy.

01
Use Separate Loan Splits
Keep private home debt and investment debt in different loan accounts.
02
Send the Money Directly
Move borrowed money straight to the investment account, settlement account or investment provider where possible.
03
Never Use It for Private Spending
Do not use the investment split for groceries, holidays, personal bills or private renovations.
04
Match the Borrower and Owner
The person or entity paying the interest and the person or entity earning the income must be checked by the tax adviser.
05
Keep Every Record
Save loan statements, bank transfers, purchase confirmations, tax statements and advice documents.
06
Review It Every Year
Check the loan, investment, tax treatment, insurance and cash flow whenever circumstances change.

Redraw

Money taken from redraw is generally a new borrowing. The tax result follows what that new borrowing is used for.

Offset Account

Taking your own cash from an offset usually does not change the original purpose of the home loan. The extra home-loan interest normally stays private.

Golden Rule

Do not move money first and ask the tax question later. Get the transaction order checked before you start.

Everything above assumes the strategy works as planned. It doesn't always.

The Big Risks

Debt recycling is still borrowing to invest.

01
The Investment Falls
A $100,000 investment can fall to $70,000 while the loan may still be close to $100,000.
02
Interest Rates Rise
The loan can become much more expensive. At 10%, interest on $100,000 is $10,000 a year.
03
Your Income Drops
Job loss, illness, parental leave or business problems can make repayments harder.
04
Investment Income Stops
A company may cut dividends, a tenant may leave or a fund may reduce distributions.
05
The Tax Deduction Changes
Tax law, your tax rate or your ability to use the deduction can change.
06
Bad Records Damage the Claim
Mixed spending and unclear transfers may reduce or delay the deduction.
07
You Sell at the Wrong Time
Fear can cause people to sell after a large fall and lock in the loss.
08
Your Home May Be at Risk
When the home secures the loan, missed repayments can put the home at risk.
The Strategy Must Work Without the Tax Benefit

Borrowing to invest only makes sense when the expected after-tax return is worth the cost and risk. A tax deduction should be a side benefit, not the reason for investing.

Before You Take the First Step

A simple checklist to discuss with your professional team.

Best Next Step

Build the strategy as a team: financial adviser for the investment, tax agent for the tax treatment, and mortgage broker or credit adviser for the loan.
