Offset account vs redraw facility: what's the difference?

Reading time: 10 minutes

When you first start comparing home loans, offset accounts and redraw facilities sound almost identical. Both reduce the interest you pay. Both let you access extra money if you need it. Banks often list them side-by-side as if they're interchangeable.

They're not.

The differences are subtle but genuinely matter, especially for property investors, anyone who might one day rent out their home, and anyone who wants reliable, instant access to their money. Getting this wrong can cost you thousands, and in some cases, create a messy tax problem that's hard to unwind.

Here's a plain-English guide to how each one works, where they differ, and how to figure out which one makes sense for you.

What an offset account actually is

An offset account is a regular transaction account, like your everyday bank account, that's linked to your home loan. The money you keep in it doesn't earn interest the traditional way. Instead, it reduces the loan balance that interest is calculated on.

Here's a simple example:

Home loan balance: $600,000
Money in offset account: $40,000
Interest is charged on: $560,000

That $40,000 sitting in the offset account saves you interest every single day it's there. Because interest on Australian home loans is calculated daily and charged monthly, even having your salary deposited into your offset account for a few weeks before it gets spent is genuinely saving you money.

The offset account functions exactly like a bank account. You get a debit card. You can set up direct debits. You can pay bills from it. Your employer can pay your salary into it. You can transfer money in and out freely, whenever you like.

One in four Australians use a home loan offset account, and as of late 2025 the total balance sitting in offset accounts across Australian lenders topped $327 billion, a figure that's grown more than 23% in just two years. Australians have clearly worked out that parking money in an offset rather than a savings account can save significantly more on home loan interest than a savings account earns.

What a redraw facility actually is

A redraw facility is not a separate account at all. It's a feature that lives inside your home loan. When you make extra repayments above your minimum monthly amount, those additional payments are recorded as "available redraw." You can then withdraw, or redraw, those funds if you need them.

Using the same numbers:

Home loan balance: $600,000
Extra repayments made: $40,000
Effective loan balance for interest purposes: $560,000

Mathematically, the interest saving is identical to having $40,000 in an offset account. The difference is in how you access that money, how quickly you can get to it, and who controls it.

With a redraw facility, you're not swiping a debit card. You're typically logging into your bank's app or website and requesting a withdrawal, which may take one to two business days to process. Some lenders set a minimum redraw amount (say, $500 or $1,000). A small number still charge a fee per redraw transaction.

And here's something that many borrowers don't know: your lender can, in theory, restrict or limit access to your redraw funds. During periods of financial stress, as some lenders demonstrated during the COVID-19 period, institutions have been known to reduce available redraw limits or change the terms of access. With an offset account, that money is yours, held in a separate account, with the same legal protections as any other bank account. The lender can't touch it.

So what's actually different?

Both features save you the same amount in interest for the same dollar amount. That's where the similarity ends.

	Offset account	Redraw facility
What it is	Separate transaction account linked to your loan	Feature inside your home loan
Access speed	Instant, just like any bank account	Usually 1 to 2 business days
Debit card access	Yes	Generally no
Salary deposit	Yes	Not typically
Fees	Often part of a loan package (~$395/yr annual fee)	Usually free
Lender can restrict access	No, it's your account	Yes, lender can change terms
Available on fixed rate loans	Rarely (varies by lender)	Sometimes, with limits
Effect on loan principal	Unchanged, money stays separate	Reduces directly, extra repayments pay down the loan
Effect on loan term	Unchanged (but interest bill shrinks)	Shortens, loan pays off earlier if funds stay in
Tax benefit for investors	Better, keeps money clearly separate	Riskier, can contaminate loan purpose

How each one affects your loan over time

This is a distinction that often gets glossed over, but it matters quite a bit in practice.

Because an offset account sits separately and never touches your loan principal, your minimum repayment stays exactly the same for the life of the loan, regardless of how much money is sitting in the offset. Your actual loan balance, scheduled repayments, and loan term don't change at all. What changes is purely how much interest you're charged each month. More in the offset means less interest; less in the offset means more. The loan itself ticks along on the same schedule as always.

With a redraw facility, the mechanics work differently. When you make extra repayments, that money goes directly into the loan and reduces your actual principal balance. Your minimum repayment doesn't automatically drop (most lenders keep it at the same dollar amount), but because your balance is lower, more of each repayment is now chipping away at principal rather than covering interest. The effect is that your loan quietly pays off earlier than originally scheduled.

Think of it this way: offset is like parking money next to your loan. Redraw is like putting it inside the loan. The interest saving in a given month is the same either way, but the underlying loan structure is different.

There's an important flip side to the redraw approach, too. If you redraw those extra funds back out, to cover an emergency, fund a renovation, or buy a car, you're essentially undoing that progress. The loan reverts toward its original payoff date. With an offset, there's nothing to reverse because the principal was never reduced in the first place. Your flexibility and your loan trajectory stay completely intact.

For borrowers who want to aggressively pay down their loan and are unlikely to need the money back, redraw can actually be a more effective debt-reduction tool. For those who want to keep their options open and maintain full liquidity, the offset's separation of savings from loan is more valuable.

The tax trap investors need to understand

This is the part most articles skip over, and it can be genuinely costly if you get it wrong.

If you currently live in your home and there's any chance you might rent it out in the future (moving in with a partner, buying a new place and keeping the old one, going overseas), the difference between offset and redraw has significant tax implications.

Here's the issue: when an investment property has an outstanding loan, the interest on that loan is generally tax-deductible. The loan purpose matters. If your loan was originally taken out to buy a home you live in and you later convert it to a rental, you need to demonstrate the loan relates to the investment property in order to claim the interest deduction.

With an offset account: Your savings and the loan are clearly separate. The loan balance is what it is, it was used to buy the property. Your savings sitting in the offset don't change the purpose of the loan.

With a redraw facility: When you redraw money from your loan for personal use (a holiday, a car, renovations to a new home), that drawn-down amount technically becomes personal debt, not investment debt. The loan purpose gets "contaminated." If you later try to claim the full loan interest as a tax deduction on a rental property, the ATO may only allow a proportion of it.

This isn't a theoretical risk. It's a real scenario that trips up property investors, and it can be impossible to unwind cleanly without refinancing entirely.

The simple rule of thumb: if you're an investor, or might become one, an offset account generally gives you cleaner tax records and fewer headaches. Speak to your accountant as well as your broker before making this decision.

The offset benefit most people never think about: it's tax-free

Here's a comparison that rarely gets made, but it's one of the most compelling arguments for an offset account, particularly if you're weighing it against keeping money in a high-interest savings account.

When your money sits in an offset account and reduces your home loan interest, that saving is not considered assessable income by the ATO. You don't pay tax on it. It's simply interest that was never charged.

Interest earned in a high-interest savings account, on the other hand, is fully taxable at your marginal rate.

Here's what that looks like in real numbers. Say you have $50,000 sitting somewhere and you're on a 37% marginal tax rate (which applies to income between $135,001 and $190,000):

	High-interest savings at 4.80% p.a.	Offset against a loan at 5.80% p.a.
Annual benefit (gross)	$2,400	$2,900
Tax payable (at 37%)	$888	$0
What you actually keep	$1,512	$2,900

The offset delivers nearly double the after-tax benefit in this example, not because the savings account rate is bad, but because the tax treatment is fundamentally different.

For borrowers on the top marginal rate of 45%, the gap is even wider. And this advantage compounds over time: every year you keep money in an offset rather than a savings account, the tax-free saving accumulates without a cent going to the ATO.

This is why an offset account is one of the most tax-efficient things an everyday Australian can do with their savings. No financial planner, no trust structure, no complexity required. The benefit is automatic from the day you link the account.

One practical note: your home loan rate needs to be competitive for this comparison to hold up. An offset against a high variable rate still outperforms a savings account on an after-tax basis, but it's another reason to make sure your underlying rate is sharp before congratulating yourself on the offset strategy.

What about fixed rate loans?

Here's a common frustration: most fixed rate loans don't offer a full offset account. Some lenders offer a partial offset on fixed rate products, but it's the exception rather than the rule. And redraw on a fixed rate loan typically comes with an annual cap, often around $10,000 in extra repayments before break costs apply.

This is one of the often-overlooked costs of fixing your rate. You gain certainty on your repayments, but you give up some of the most useful tools for reducing your interest bill over time.

If you're considering fixing and you use your offset account actively, meaning you keep a meaningful balance in there, have your salary deposited into it, use it for everyday spending, it's worth factoring in what you'd lose. The interest saved through a well-used offset account can sometimes outweigh the benefit of a lower fixed rate.

Which one is right for you?

Neither is universally better. Here's a practical guide based on your situation:

An offset account probably suits you better if:

You want to use it as your everyday transaction account
You get paid a salary and want it deposited directly (even temporarily, it reduces your interest daily)
You want instant, unrestricted access to your money at any time
You're an investor, or might become one, the cleaner tax position matters
You tend to keep a meaningful amount in savings

A redraw facility probably suits you better if:

You want to keep things simple and avoid a separate account or annual package fee
You're disciplined about making extra repayments but don't need to access the money often
You're an owner-occupier with no plans to ever use the property as an investment
You find the slight "friction" of redraw helpful, it makes dipping in less tempting
Your loan has a competitive rate without needing a full package

And here's something worth knowing: many lenders offer both features on the same loan. If you have a variable rate loan with an offset account, it often also comes with a redraw facility. You don't always have to choose one or the other. It depends on what your loan product includes.

A question worth asking about your current loan

One in ten mortgage holders believe their offset account is automatically linked to their home loan by the lender, but it's not. You need to set it up. Only one in four borrowers have actually confirmed that their offset account is properly linked and working.

If you have an offset account and haven't verified it's correctly connected to your loan, it might be sitting as a standalone savings account earning minimal interest, completely missing the point. Log in to your banking app and confirm the balance of your offset is visibly reducing your "interest-bearing balance." If you're not sure, call your lender and ask them to confirm.

Does your current loan even offer these features?

This is where a lot of borrowers discover they've been on the wrong product for years.

Basic "no-frills" variable rate loans, which sometimes advertise the lowest headline rates, often don't include an offset account. For a borrower who could be keeping $30,000 to $80,000 in an offset, the absence of that feature can actually cost more in interest than the small rate premium on a loan that includes it.

Before assuming your loan is competitive based on rate alone, it's worth checking what features you do and don't have, and whether a different loan structure would serve you better overall.
