Mortgage offset errors have led to Australian banks paying $55 million in compensation, and you could be owed thousands. Learn how to check if your home loan offset account has been working correctly and claim what’s rightfully yours.
What Is a Mortgage Offset Account?
A mortgage offset account is a savings or transaction account linked to your home loan. The balance in this account is offset against your outstanding mortgage principal, reducing the interest you pay. For example, if you owe $400,000 on your mortgage and have $50,000 in an offset account, you only pay interest on $350,000.

This mechanism can save you thousands in interest over the life of your loan and help you pay off your mortgage faster. However, when banks fail to properly link or manage these accounts, you may be overcharged interest without knowing.
ASIC Report Reveals Widespread Failures
The Australian Securities and Investments Commission (ASIC) reviewed over 200,000 home loans from eight major banks. The report found weaknesses in how all lenders set up, monitored, and managed offset accounts, leading to customers missing out on promised savings.
In one extreme case, a borrower was overcharged more than $3,500 in interest in a single month. ASIC warns that the total compensation figure of $55 million is likely to climb as more issues are identified.
Which Banks Are Affected?
The report does not name all eight banks, but major lenders including Commonwealth Bank, Westpac, NAB, and ANZ are known to have paid remediation. Smaller lenders and credit unions may also be involved. If you have a mortgage with an offset account, you could be affected regardless of your bank.
How to Check If You’re Owed Money
Checking your mortgage offset account is straightforward. Follow these steps to see if you’ve been overcharged:
- Log into your internet banking or lender’s app and review your mortgage account summary.
- Verify that your offset account balance is correctly reflected as reducing your interest charges.
- Compare your interest charged against what you should be paying based on your offset balance.
- Contact your bank’s customer service and ask for a review of your offset account setup.
If you find discrepancies, you can lodge a complaint with your bank’s internal dispute resolution team. If unresolved, escalate to the Australian Financial Complaints Authority (AFCA).
Data Table: Impact of Offset Errors
| Offset Balance | Mortgage Balance | Interest Paid (Without Offset) | Interest Paid (With Offset) | Monthly Overcharge |
|---|---|---|---|---|
| $0 | $400,000 | $1,800 | $1,800 | $0 |
| $50,000 | $400,000 | $1,800 | $1,575 | $225 |
| $100,000 | $400,000 | $1,800 | $1,350 | $450 |
As shown, even a $50,000 offset balance can save you $225 per month. If your bank fails to apply the offset correctly, you could be losing that amount every month without realising.
