How to Choose Between Offset and Redraw Facilities

An offset account and a redraw facility both reduce the interest charged on your home loan, but they operate differently and suit different financial structures.

The distinction matters if you plan to convert your property to an investment, need regular access to funds, or want to preserve borrowing capacity for future purchases. Both features reduce the balance on which interest is calculated, but one sits outside your loan as a linked transaction account while the other holds funds within the loan itself. That structural difference affects flexibility, lender control, and tax treatment.

How an Offset Account Reduces Interest

An offset account is a transaction account linked to your home loan. The balance in the offset account is subtracted from your outstanding loan balance when the lender calculates interest each day. If you have a loan balance of $500,000 and $20,000 in your offset account, you pay interest on $480,000. The funds in the offset account remain fully accessible at any time through transfers, direct debits, or card transactions.

Offset accounts are typically available on variable rate loans and some split loan structures. They are less commonly offered on fixed rate products. Lenders may charge a higher interest rate or an annual fee for a loan package that includes a full offset account. In our experience, the cost of the offset feature is often recovered within the first year if you maintain a balance of $15,000 or more, depending on the rate differential and your loan amount.

How a Redraw Facility Returns Paid Funds

A redraw facility allows you to withdraw extra repayments you have made above the minimum required amount on your loan. When you pay more than the scheduled repayment, the excess reduces your loan balance and lowers the interest charged. You can then apply to redraw those additional funds if needed. The application is usually processed online, though some lenders require a phone request or a form. Most lenders do not charge a redraw fee on variable rate loans, but fixed rate products often have restrictions or fees attached.

Redraw is available as paid funds, not as a separate account. Once redrawn, the loan balance increases again and interest is recalculated accordingly. The distinction between available redraw and the minimum balance required can create confusion, particularly when lenders recalculate your loan schedule after a redraw or adjust the available amount without notice.

Access and Control Differences

Offset balances are immediately accessible without lender approval. Redraw requests may be declined, delayed, or restricted depending on your loan terms and the lender's policy. Lenders can suspend or reduce redraw access during periods of economic uncertainty, as occurred in Australia during the early months of the pandemic. Some lenders also impose minimum redraw amounts, maximum redraw frequencies, or restrict redraw entirely if you switch to interest-only repayments.

Consider a buyer who purchases an owner occupied home loan in Deakin with a variable rate and full offset account. They direct their salary into the offset account and leave funds there until needed for expenses. Their loan balance remains unchanged, but the daily interest calculation reflects the offset balance. Six months later, they decide to purchase an investment property. Because the funds were never paid into the loan, the original loan balance has not decreased, and they retain full access to the offset funds without affecting their tax position. If they had used redraw instead, withdrawing those funds after the property converts to an investment use would create a mixed-purpose loan with non-deductible debt.

Tax Treatment When Converting to Investment

If you convert your home to an investment property, interest on the loan becomes tax deductible to the extent the borrowed funds are used to produce assessable income. Funds held in an offset account do not form part of the loan balance, so withdrawing them does not increase the loan or create a tax issue. Redraw works differently. When you redraw funds, you increase the loan balance. If the original loan purpose was private and the redrawn funds are used for private purposes, the additional interest remains non-deductible even after the property becomes an investment.

This creates a tax issue that many borrowers do not identify until they speak with an accountant after settlement. If you plan to retain your current home as an investment and purchase another property to live in, an offset account preserves the integrity of the loan purpose. Redraw does not. The Australian Taxation Office has issued guidance on this point in TR 2023/1, which replaced earlier rulings and clarified that the deductibility of interest depends on the use of borrowed funds, not the security for the loan.

Split Loan Structures with Offset

A split loan divides your borrowing across two or more accounts, typically combining a fixed rate portion with a variable rate portion. Offset accounts can only be linked to the variable portion. The fixed rate portion does not benefit from offset, though it may offer redraw with conditions. In a split structure, you would direct surplus funds into the offset account linked to the variable portion to reduce interest on that component while maintaining rate certainty on the fixed portion.

This approach works well for buyers in Canberra who want partial protection from rate increases but need flexibility for irregular income or planned expenses. A buyer who works in the public service and receives annual bonuses or regular salary increments might offset those amounts against the variable portion and preserve access without triggering break costs or losing redraw if the lender adjusts policy. We regularly see clients in Deakin and Griffith using split structures with offset to manage both certainty and access, particularly when they are building equity toward a second purchase.

Lender Policy Variation on Redraw

Redraw policies differ significantly across lenders. Some allow unlimited free redraws on variable loans with online access. Others impose a fee per redraw transaction, cap the number of redraws per year, or require a minimum redraw amount such as $500 or $1,000. On fixed rate loans, redraw is often restricted entirely or subject to a fee of $300 or more per request. Several lenders also recalculate the loan term when you make extra repayments, which can reduce the available redraw amount if the lender shortens the remaining term rather than reducing the minimum repayment.

If you are comparing home loan features, confirm whether the redraw balance is calculated as total extra repayments or as the amount available after the lender recalculates the loan term. This is not standardised across lenders, and the difference can be several thousand dollars on a loan where you have been making additional repayments for several years.

When Offset Accounts Cost More Than They Save

A loan package with an offset account typically has a higher interest rate, an annual package fee, or both. If the rate difference is 0.15% per annum and the package fee is $395, you need to maintain an average offset balance high enough to generate interest savings that exceed the additional cost. On a $400,000 loan with a 0.15% rate difference, the additional interest cost is $600 per year. Adding the package fee brings the total cost to $995. To break even, your average offset balance would need to save at least that amount in interest. The exact break-even point depends on your loan size and the prevailing variable rate, but in most cases an average offset balance below $10,000 will not justify the additional cost.

If you do not maintain a consistent surplus or you prefer to pay down the loan balance directly, a loan without an offset feature and a lower base rate may deliver lower overall interest. Lenders offering no-frills variable loans often provide redraw at no cost, which may suit buyers who make lump sum repayments irregularly rather than holding a daily transaction balance.

Using Offset to Preserve Borrowing Capacity

Borrowing capacity is assessed on your current loan balance, not your redraw balance. If you reduce your loan balance by $30,000 through extra repayments and then apply for a second loan, your borrowing capacity is calculated based on the lower balance. If you hold $30,000 in an offset account instead, your loan balance remains unchanged and your borrowing capacity reflects the higher debt, which can reduce the amount a lender will approve for a second purchase. However, your offset balance is treated as genuine savings, which may strengthen your application in other ways.

This difference is relevant for buyers planning to retain their current property and purchase another. In that scenario, holding funds in offset preserves the deductibility of interest on the first loan without reducing the assessed debt. For buyers purchasing their first investment property, the approach depends on whether the goal is to reduce the loan balance before refinancing or to maintain separation between owner-occupied and investment debt.
