How to Restructure Your Home Loan To Maximise Legit Tax Deductions
Written and reviewed by James Chee, CPA · Last reviewed
Clear, practical steps to restructure your home loan so more interest becomes tax‑deductible over time – without breaking ATO rules or muddling loan purposes.
Key Takeaway
Restructuring a home loan to maximise tax-deductible interest is done by separating non-deductible home debt and deductible investment debt into clean loan splits and strictly matching each split to its purpose, in line with ATO “loan tracing” rules. Interest is deductible only where borrowings are used to produce assessable income, not simply because the loan is secured against a property, so redraw used for private expenses can contaminate deductibility. A practical insight is to channel all surplus cash to non-deductible home splits while using dedicated investment splits and offsets, not redraw, for investing and private cashflow.

Home loan tips for digital creators and freelancers
If you’re reshaping your loan for better tax outcomes, this video explains key home loan basics for digital creators and freelancers.

If you earn your revenue through digital creator platforms or rolling freelance contracts, standard retail banks are programmed to treat you like a high-risk borrower. When their automated systems look for a standard corporate payslip, and find multiple payment platforms instead, they hit 'reject'. We don't use those systems. We use alternative documentation pathways specifically built for modern digital income. We utilise a 12-month smoothing model that verifies your true capacity straight from your bank deposits, entirely bypassing the outdated PAYG paperwork gatekeepers.

Clear, practical steps to restructure your home loan so more interest becomes tax‑deductible over time – without breaking ATO rules or muddling loan purposes.
Read the full guide on tailoredloans.sydneyYou can’t just “make your home loan tax‑deductible”, but you can restructure it so more of your future interest is deductible, by separating home and investment borrowing and following ATO loan tracing rules.
Interest is deductible when the borrowed money is used to produce assessable income (ATO TR 2000/2), not simply because the loan is secured against an investment or your home.
1. The core idea: turn bad debt into good debt, within the rules
At a high level, the strategy is:
- Keep your home loan (non‑deductible) in one clean split.
- Create separate investment and/or business splits.
- Direct extra repayments to the home split.
- Re‑borrow from investment splits for income‑producing purposes only.
Over time, more of your total debt becomes tax‑deductible while your home loan shrinks. This is the engine behind debt recycling – covered in more detail in /insights/beginners-guide-debt-recycling-australian-homeowners.
Quick worked example
- $800,000 owner‑occupied home loan
- $3,000/month surplus after living costs
If you simply pay your minimum and invest $3,000/month from cash, your home loan barely moves.
If instead you:
- Split into $650,000 home + $150,000 investment
- Hammer extra $3,000/month into the home split
- Re‑borrow from the investment split to buy ETFs/property
…you gradually convert non‑deductible home debt into investment debt that may be deductible.
2. Loan tracing: how the ATO decides what’s deductible
The ATO looks at how each dollar was used, not what secures the loan. This is called loan tracing.
Key rules:
- Purpose test – Borrowings must be used to produce assessable income (rent, business income, dividends, interest) to claim interest.
- Mixed‑purpose loans – If a loan funds both investment and private spending, interest must be apportioned.
- Redraw risk – Redrawing from an investment or recycling split for private expenses contaminates the loan and forces messy apportionment (see fact 3 above).
This is why structure matters. Good structure makes loan tracing simple and defensible.
Clean structure usually means:
- One or more home splits – non‑deductible, P&I.
- One or more investment splits – potentially deductible, often IO.
- Optional business split – dedicated to business purposes.
