The offset account is the most misused tool in property finance: linked to the wrong loans, confused with redraw and mistaken for a savings account. Episode 79 of Finance This, Property That explains how offsets actually work and how the right structure protects both interest and tax position.
Offset versus redraw: the difference that matters
An offset is a separate transaction account whose balance reduces the interest calculated on the linked loan. Your money remains yours, available on demand. Redraw is extra repayments sitting inside the loan, accessed on the lender's terms, and withdrawing it can carry different tax consequences for investors. On a statement they look like cousins. In practice, and especially at tax time, they are different species.
The mistakes costing borrowers money
- Offset linked to the wrong loan. Cash offsetting a small or deductible loan while the big non-deductible one charges full interest.
- Savings accounts impersonating offsets. Money earning trivial interest while a loan next to it compounds.
- Cash scattered across accounts that offset nothing.
- Redraw treated as an offset. Fine until the money is needed, or until the tax treatment surprises.
Each mistake is quiet. None of them show up as a fee. They just cost interest every month until someone looks.
Case study: the $1 million restructure
The episode's real client example restructures a $1 million home loan using multiple offsets and equity release strategies, improving the clients' position by over $5,000 a month. The mechanics matter more than the number: the right debts offset, the equity repositioned and the structure aligned with how the household actually banks.
Structure and tax: keep the debts separated
The general principle the episode explains: spare cash belongs against non-deductible debt first, because offsetting an investment loan reduces interest that would otherwise be deductible while the home loan keeps charging in full. Keeping deductible and personal debt cleanly separated is the foundation the debt recycling strategies build on. Specific tax outcomes vary, so the numbers belong in front of your accountant.
Own your banking setup
The closing message is ownership: know which account offsets which loan, route income where it works hardest and review the structure whenever a loan changes. Financial literacy about your own setup is free, and it is the cheapest interest saving available.

Key questions this episode answers
What is the difference between an offset account and redraw?
An offset is your own transaction account reducing interest on the linked loan; redraw is extra repayments inside the loan, accessed on the lender's terms with potentially different tax consequences. Similar on paper, very different in practice.
What are the most common offset mistakes?
Wrong loan linked, savings accounts mistaken for offsets, cash scattered across non-offsetting accounts and redraw treated as an offset. Each costs interest quietly.
Why shouldn't your investment loan usually hold the offset?
Offsetting deductible debt reduces deductible interest while the non-deductible home loan charges in full. Point spare cash at personal debt first and keep the two cleanly separated, with the specifics confirmed by your accountant.
What did the client restructure achieve?
Over $5,000 a month of improvement from restructuring a $1 million home loan with multiple offsets and equity release. One client's outcome, dependent on their position and assessment.
How should investors organise banking around offsets?
Deliberately: know the links, route income to the hardest-working offset and review the structure whenever loans change.
The takeaway
Offsets do not fail people. Setups do. The tool is simple; the structure around it decides whether it saves thousands or quietly does nothing. Check the links, separate the debts and make your cash work against the debt that deserves it.
