Offset Account vs Redraw Australia 2026: How They Work and Which Saves More
How offset accounts and redraw facilities actually work in Australia in 2026 — the practical differences for accessibility, the tax implications for investment vs owner-occupied loans, and worked examples showing how much interest you actually save on a typical $600,000 home loan.

An offset account is a transaction account linked to your home loan where every dollar in the account reduces the loan balance for interest calculation purposes — without actually paying down the loan. A redraw facility is a feature of your loan that lets you make extra repayments and then withdraw them later if you need the cash. Both achieve the same goal of reducing the interest you pay, but they have important practical and tax differences. With variable mortgage rates around 6% in 2026, even modest sums in an offset account or redraw can save thousands of dollars per year. This guide explains how each works, when to use which, and the tax trap that catches many investment property owners.
How an Offset Account Works
An offset account looks and works like a normal everyday transaction account: you can deposit your salary, pay bills, use the linked debit card, and access internet banking. The difference is that it is linked to your home loan, and the bank treats every dollar in the offset account as if it were being used to pay down the loan for interest calculation purposes — without actually moving the money. Example: $600,000 loan at 6% with $50,000 in the linked offset account. The bank calculates interest on $550,000, not $600,000, saving you $3,000 a year ($250 a month) in interest. The $50,000 remains fully accessible for everyday spending. Most lenders charge a small monthly fee ($0-$15) for offset accounts, usually waived if you pay off the loan annually.
How a Redraw Facility Works
A redraw facility lets you make extra repayments on top of your scheduled minimum, and then withdraw those extra repayments later if you need cash. Example: $600,000 loan with $50,000 of extra repayments made over the years. Your loan balance for interest calculation is now $550,000 (saving the same $3,000 a year as the offset example). If you later need cash, you can request a redraw of up to the available extra repayments. Redraw is a feature built into the loan itself, with no separate transaction account. Most lenders allow free online redraws but some charge $10-$30 per redraw or have minimum amounts ($500-$1,000). Some loans have minimum redraw amounts and waiting periods.
Offset vs Redraw: Side by Side
Both achieve identical interest savings when used correctly. The differences are in accessibility, ownership, and tax treatment.
| Feature | Offset account | Redraw facility |
|---|---|---|
| Interest saving | Same effect | Same effect |
| Daily access | Yes (debit card, BPAY) | Online or call only |
| Money belongs to | You (your bank account) | The bank (you redraw) |
| Ownership status | Your savings | Bank loan balance |
| Monthly fee | $0-$15 typically | Usually free |
| Investment property tax | Safe — money stays yours | Tax trap if you redraw |
| Limit | No limit | Limited to extra repayments |
| Minimum amount | None | Some loans set minimums |
The Investment Property Tax Trap
This is critical for property investors and is the main reason offset accounts are preferred over redraw for investment loans. When you make extra repayments on an investment loan and later REDRAW them for personal use (a holiday, a car, anything not income-producing), the redrawn amount is treated as a NEW LOAN for personal purposes, and the interest on that portion is no longer tax-deductible. Example: $600,000 investment loan, $50,000 extra repaid, then $30,000 redrawn for a holiday. The interest on $30,000 of the loan is now non-deductible. With an offset account, the $50,000 was always your savings sitting separately — you can spend it on anything without affecting the deductibility of the loan interest. Always use offset accounts (not redraw) for investment property loans.
Worked Example: $600,000 Loan with $80,000 Offset
An owner-occupied $600,000 loan at 6.0% variable rate over 30 years has a base monthly payment of around $3,597 and total interest over the life of the loan of about $695,029. With $80,000 sitting permanently in an offset account, the effective loan balance is $520,000 from day one.
| Scenario | Monthly payment | Total interest | Years to pay off |
|---|---|---|---|
| No offset | $3,597 | $695,029 | 30 |
| $30K offset | $3,597 | $571,200 | ~26.5 |
| $60K offset | $3,597 | $461,800 | ~23.5 |
| $80K offset | $3,597 | $396,300 | ~21.5 |
| $100K offset | $3,597 | $334,700 | ~19.5 |
Frequently Asked Questions
What is an offset account in Australia?+
An offset account is a transaction account linked to your home loan where every dollar in the account reduces the loan balance for interest calculation purposes. You can deposit your salary, pay bills and use a linked debit card just like a normal bank account, but the bank calculates your loan interest on the loan balance MINUS the offset balance. A $50,000 offset balance against a $600,000 loan means interest is calculated on $550,000, saving you about $3,000 a year at 6% variable rate.
Is an offset account or redraw better?+
For owner-occupied loans, both save the same interest. The choice depends on accessibility (offset has debit card access, redraw is online only) and fees (offset typically charges $0-$15 monthly, redraw is usually free). For investment property loans, offset is almost always better because of the tax trap with redraw — when you redraw for personal use, the interest on the redrawn portion becomes non-deductible. Money in an offset account remains your savings and can be spent on anything without affecting loan deductibility.
How much interest does an offset account save?+
The interest saving equals your offset balance multiplied by the loan interest rate. A $50,000 offset against a 6% loan saves $3,000 per year, or $90,000 over 30 years. The compounding effect is even greater because the saved interest reduces the loan balance faster, which then reduces interest further. A $50,000 offset on a $600,000 30-year loan typically saves around $130,000-$160,000 in total interest and shortens the loan by 3-5 years compared to no offset.
Should I put my emergency fund in my offset account?+
Yes, almost always. Your emergency fund earns no return in a bank account (or maybe 4-5% in a high-interest savings account, fully taxed at your marginal rate). The same money in an offset account effectively earns the equivalent of your mortgage rate (6%+ in 2026), tax-free, because you are not paying interest on that portion of the loan. For someone in the 30%+ marginal tax bracket, the after-tax benefit of an offset account is roughly twice the after-tax interest you would earn on a savings account.
Can I have multiple offset accounts?+
Yes, with most lenders. Many Australian banks now offer multiple offset accounts linked to a single home loan, letting you create separate accounts for different purposes (everyday spending, savings goals, emergency fund, holiday fund, etc.) while still all reducing the loan interest. This is convenient for budgeting without losing the offset benefit. Some lenders charge per offset account, others bundle them — check the product disclosure statement before signing up.
Does an offset account affect my tax?+
Not for owner-occupied loans (which have no tax implications). For investment property loans, the offset account is the SAFE way to hold extra cash — money in the offset belongs to you and can be withdrawn for any purpose without affecting the loan interest deductibility. By contrast, redraw on an investment loan creates a tax trap: redrawing for personal purposes makes the interest on the redrawn portion non-deductible, sometimes permanently affecting the loan deductibility.
What is the difference between fixed and variable rate offsets?+
Most fixed-rate Australian home loans do NOT allow offset accounts (or only allow partial offsets, which save less interest). Variable rate loans almost always allow full offset accounts. This is one of the biggest hidden trade-offs of fixing your rate — you give up the offset benefit. If you have a substantial offset balance ($30,000+), staying variable can produce more total savings than locking in a slightly lower fixed rate. Some lenders offer split loans where part is fixed and part is variable with offset.
Are offset accounts safe?+
Yes. Money in an offset account is held by your bank under the same regulations as any other deposit account, including the federal government Financial Claims Scheme guarantee of up to $250,000 per ADI (Authorised Deposit-taking Institution) per account holder. Your money is fully accessible at any time and is legally yours (not the bank's). The offset arrangement is purely a calculation method for the loan interest — it does not change the legal ownership of your savings.
