Two of the most common features attached to Australian home loans — offset accounts and redraw facilities — both let you reduce the interest you pay by using extra funds against your mortgage, but they work differently in practice, and the right choice often comes down to your financial habits as much as the numbers.
How an Offset Account Works
An offset account is a separate transaction account linked to your home loan. The balance in that account is “offset” against your loan balance when interest is calculated — so if you have a $600,000 loan and $50,000 sitting in a 100% offset account, you only pay interest on $550,000. Your everyday salary, savings, and spending can sit in this account, offsetting interest daily while remaining fully accessible, just like a regular transaction account.
How a Redraw Facility Works
A redraw facility lets you make extra repayments directly onto your loan, reducing the principal (and therefore future interest) immediately, while still allowing you to “redraw” those extra funds back out later if needed. The extra funds effectively become part of the loan itself rather than sitting in a separate account.
Key Practical Differences
- Accessibility: Offset accounts typically function like a normal transaction account with instant access via card or transfer. Redraw access can sometimes involve a short delay, a minimum redraw amount, or occasionally a fee, depending on the lender.
- Tax treatment for investment properties: This is a significant and often misunderstood distinction. Redrawing funds from an investment loan for a private purpose can affect the deductibility of interest on that loan, since the purpose of the funds matters for tax purposes. Offset account balances don’t have this issue, since the loan balance itself never changes. If you have or plan to have an investment property, this difference is worth discussing directly with a tax adviser or accountant before choosing a structure.
- Fees: Full-featured 100% offset accounts sometimes come with a package fee attached to the loan; redraw facilities are more commonly included at no extra cost, though this varies by lender.
Which Suits Which Buyer
An offset account tends to suit buyers who want their everyday savings actively reducing interest while remaining instantly accessible, and is generally the safer default for anyone who currently has or may later have an investment property, given the tax treatment described above. A redraw facility can suit buyers who want to make disciplined extra repayments and are less concerned with instant access, and who don’t currently have investment lending considerations.
Getting the Structure Right From the Start
Because switching loan structures later can involve refinancing costs, application fees, or a new valuation, it’s worth getting this decision right at the outset rather than treating it as easily reversible. A mortgage broker can model both structures against your actual savings behaviour and future plans (including whether the property might become an investment down the track) to help you land on the right fit — this is exactly the kind of structuring conversation firms like Vista Financial Group work through with clients before settlement, not after.

Frequently Asked Questions
Can I have both an offset account and a redraw facility on the same loan?
Many loan products do allow both, though the specific combination and any associated fees vary by lender — worth confirming directly when comparing loan products.
Does a 100% offset account always come with extra fees?
Not always, but many lenders bundle full offset functionality into a package loan that carries an annual fee — it’s worth comparing the fee against the actual interest savings you’d realistically achieve given your typical account balance.
What happens to my offset account if I refinance to a different lender?
You’d generally need to set up a new offset account with the new lender as part of the refinance; any funds in your existing offset account would need to be transferred as part of that process.
Key Takeaway
Both structures can reduce your interest bill, but they behave differently around accessibility, fees, and — critically for investment property owners — tax treatment. Match the structure to your actual saving habits and future plans, not just the headline feature list.
