What Is an Offset Account?
An offset account is a transaction account linked to your home loan. The balance in that account is subtracted from your outstanding loan amount before interest is calculated—usually daily. If you have a $600,000 loan and $40,000 in a 100% offset account, you pay interest on only $560,000.
In 2026, the Reserve Bank of Australia (RBA) cash rate sits at 4.35%, with standard variable mortgage rates around 6.0% p.a. for owner-occupiers (APRA-regulated lenders). At that rate, the $40,000 offset example saves approximately $2,400 in interest in the first year and shortens a 30-year loan by roughly 3 years and 10 months if the balance is maintained.
Offsets come in two common forms:
- 100% offset account: The full balance offsets the loan. This is the standard on competitively priced home loans.
- Partial offset account (e.g., 50%): Only a portion of the balance offsets the loan, reducing effective savings. Avoid these unless the interest rate is substantially lower.
Key features:
- No lock on your money; you can withdraw, transfer, and spend as needed.
- May attract monthly or annual package fees (often $8–$15/month or $395/year packaged with other products).
- No change to the original loan contract, preserving the loan’s purpose for tax purposes.
What Is a Redraw Facility?
A redraw facility lets you access extra repayments you’ve made above your minimum required repayments. For example, if your required monthly payment is $2,800 and you pay $3,500, the extra $700 is available to redraw later, subject to the lender’s conditions.
Like an offset, redraw reduces your loan balance for interest calculation purposes. The interest-saving effect is identical as long as the accumulated extra repayments stay in the loan. However, redraw money isn’t “yours” in the same legal sense—it’s the lender agreeing to let you re-borrow the overpaid amount.
In 2026, most major Australian lenders offer free online redraw, but conditions apply:
- Minimum redraw amounts (commonly $500–$1,000).
- Some lenders limit the number of free redraws per year before fees apply.
- Fixed-rate loans often cap redraw (e.g., the greater of $10,000 or 5% of the loan balance per annum) and may charge a break fee.
Redraw can be a strong forced-savings tool because the extra money is slightly out of reach, reducing impulse spending.
Offset vs Redraw: At-a-Glance Comparison Table
| Feature | Offset Account | Redraw Facility |
|---|---|---|
| How it works | Separate linked transaction account; balance offsets loan daily | Access extra repayments made above minimum payments |
| Interest saved | Same effective saving as long as money is maintained | Same effective saving if extra repayments are not redrawn |
| Access to funds | Instant via debit card, transfer, ATM | 1–3 business days; minimum redraw limits |
| Fees (typical 2026) | $8–$15/month or $395/year package fee; may be waived on some basic loans | Usually free for online redraw; fees for branch-assisted redraws |
| Tax impact (investors) | Neutral; loan purpose unchanged | Can mix loan purpose, limiting future interest deductions—per ATO Tax Ruling TR 2000/2 |
| Loan type availability | Variable-rate loans; some fixed-rate loans offer partial offset | Most variable and some fixed-rate loans, but fixed-rate redraw is often restricted |
| Discipline required | Requires cashflow discipline not to spend the offset balance | Acts as a barrier, helping disciplined saving |
Scenarios: Where the Savings Actually Diverge
Scenario 1: Owner-occupier with consistent savings
Sarah has a $750,000 owner-occupied loan at 6.1% p.a. and keeps a $50,000 emergency fund. In an offset account, she saves $3,050/year in interest, always has instant access, and pays a $395 annual package fee. If she instead parks that $50,000 as extra repayments into a redraw, she saves the same $3,050/year interest but loses instant access and may need 48 hours to withdraw. For Sarah, the offset delivers equal savings plus superior liquidity.
Scenario 2: Investor planning to convert a former home to rental
Jake purchased a home in 2022, now valued at $1.2 million, with a $400,000 loan. In 2026 he moves interstate and rents out the property. While living there, he placed $80,000 into a redraw facility, thinking he was paying down the loan. When he later redraws that $80,000 to buy a new home, the ATO sees the redrawn portion as a new borrowing for a private purpose. His deductible interest is now limited to the portion of the loan still attributed to the rental property—potentially costing him $4,000+ per year in lost tax deductions. Had Jake used an offset account, the $80,000 withdrawal would leave the original $400,000 loan intact, fully deductible. For investors and potential investors, the offset account’s tax clarity provides a large long-term advantage.
Scenario 3: Borrower who struggles with spending discipline
Megan knows she will spend money if it’s too accessible. She channels every spare dollar into her loan via redraw, building a $35,000 buffer over three years. The 1–3 day delay to redraw acts as a financial “cooling-off” period. The interest saving is identical to an offset, and she avoids monthly offset fees. In 2026, some no-frills variable loans from mutual banks and online lenders offer free redraw with no offset option, making redraw the better budget-choice for disciplined savers who don’t need daily liquidity.
The 2026 Tax Equation: Why Loan Purpose Matters
The Australian Taxation Office (ATO) treats redraw and offset very differently. Under TR 2000/2, the deductibility of interest depends on what the borrowed money is used for, not the security property. Extra repayments into a redraw facility are treated as permanently reducing the loan balance; a subsequent redraw is a new borrowing. If that new borrowing is for personal use (e.g., buying a car, depositing on a new home), the interest on that portion is not deductible, even if the original loan was for an investment property.
An offset account never changes the loan contract. Withdrawals from offset are simply your own savings, so the underlying loan purpose remains intact. As of the ATO’s 2025–26 compliance focus, data matching with financial institutions has increased, making incorrect apportionment of loan interest a high-risk audit flag.
Data point: According to the ATO’s 2024 Rental Property Schedule data, 85% of rental property owners claimed interest deductions, totalling $18.6 billion. Misclassifying a mixed-purpose loan after redraw can claw back those deductions and incur penalties.
How to Model Your Personal Savings: A Simple Calculation
To compare offset and redraw for your situation, use this formula in 2026:
Annual Interest Saving = Balance in Offset (or Extra Repayments) × Mortgage Rate
Then, compare fees:
- Offset: annual package fee (typically $395) or monthly fee ($8–$15)
- Redraw: usually $0 for standard online redraw
The breakeven point for a $395 annual offset fee at 6% is just $6,583 of average offset balance. If you consistently maintain more than that, the offset pays for itself.
Assumptions and limitations:
- This ignores marginal tax rates (relevant if comparing to investing elsewhere).
- The effective benefit of offset is tax-free, equivalent to earning the mortgage rate after tax—an important yardstick against taxable investments.
Q: Does an offset account really save more than a redraw facility?
In pure interest-saving maths, they can be equal if you leave extra funds untouched. However, offset accounts typically save more for owner-occupiers because they keep money instantly accessible and avoid triggering capital gains tax issues when converting a property to an investment.
Q: Is redraw money taxed differently from offset money?
No, redrawing extra repayments is not directly taxed. The tax issue arises for investors: if you redraw for personal use, the ATO may treat the redrawn portion as a new borrowing, mixing loan purpose and limiting interest deductions. Offset withdrawals do not alter the loan contract, so the full deductible debt remains intact.
Q: Which is better if I plan to turn my home into an investment property?
An offset account is strongly preferred. By keeping savings in offset rather than paying down the loan, you preserve the original loan balance. When the property becomes income-producing, the full loan interest remains deductible. Using redraw to later extract equity for a non-investment purpose can permanently reduce deductible interest.
Q: Can I have both an offset account and a redraw facility?
Yes, many variable-rate home loans in 2026 offer both. You might use offset for daily liquidity and deposit any surplus into the loan via redraw for a forced-savings layer. Just check that the package fee covers both features without duplication.
Q: Are there any credit score implications for using redraw frequently?
No. Using a redraw facility does not create a credit inquiry or directly affect your credit score because you are accessing your own extra repayments, not applying for new credit. Lenders may, however, review your overall account conduct during hardship assessments.
Final Verdict: Which Saves More?
For the majority of residential borrowers in 2026, an offset account provides slightly greater net value because of three factors:
- Liquidity premium – instant access without delays or minimums.
- Tax integrity – no risk of contaminating loan purpose.
- Behavioural flexibility – works well for those who can manage a transaction account, and the fee gap vs redraw has narrowed.
Redraw remains a sharp tool for borrowers who want to minimise fees and need a barrier between savings and spending. It can also be the only option on ultra-low-cost basic variable loans that don’t include an offset.
Choose offset if:
- You are an owner-occupier and value instant access.
- You might convert the home to an investment property.
- You keep a substantial balance (above $7,000 average) that easily offsets the annual fee.
Choose redraw if:
- You are on a tight budget and want to avoid monthly fees.
- You need a psychological barrier to control spending.
- You are certain the property will never become an investment and you don’t need immediate liquidity.
