The Hidden Risk of Using Redraw on Your Home Loan

Could accessing your redraw today cost you tax benefits tomorrow? For a lot of homeowners, the answer is yes, and they have no idea until it’s too late.

Many of us make extra repayments into the home loan to get ahead faster, which is a smart habit. But if there’s any chance you’ll one day turn your current home into an investment property, how you access those extra repayments matters enormously. This is where the redraw vs offset question stops being a technicality and starts being a decision that can shape your future tax position.

Here’s what every homeowner with an eye on property investing should understand before they redraw a cent.

First, the Difference Between Redraw and Offset

Both a redraw facility and an offset account can save you interest, but they work in fundamentally different ways, and that difference is the whole story here.

A redraw facility lets you pull back extra repayments you’ve made into your loan. When you pay extra, you’re reducing the loan balance, and redraw lets you access that money again later.

An offset account is a separate transaction account linked to your loan. The balance sits against your loan and reduces the interest you’re charged, but legally it’s your savings, not a repayment of the loan.

That legal distinction, repayment versus savings, is exactly what the tax outcome turns on.

Why Redraw Can Create a Tax Problem

Here’s the part most people don’t realise, and it’s the heart of the redraw vs offset question. When you redraw funds from your home loan, the purpose of that redrawn money matters, not the original purpose of the loan.

The Australian Taxation Office, under Taxation Ruling TR 2000/2, treats each redraw as a new borrowing. What determines whether the interest is deductible is how you use the funds at the time you redraw them, not what the loan was originally for or what it’s secured against.

So picture this. You pay extra into your home loan, then later redraw those funds to buy a car, renovate, or take a holiday. That redrawn portion is now borrowing for personal use.

If you later rent out that property, part of the loan may relate to the original property purchase (potentially deductible), while the redrawn amount used for personal expenses is not. Your loan has become what’s known as a mixed-purpose loan, and untangling the deductible portion from the non-deductible portion at tax time is messy, ongoing, and easy to get wrong.

Why Investors Often Prefer an Offset Account

An offset account can give you the same interest-saving benefit while keeping your loan structure clean. Because the money in an offset is legally your savings rather than a repayment, withdrawing it doesn’t change the purpose of your loan, so it doesn’t create the mixed-purpose problem.

The advantages that make offset the preferred choice for anyone who might invest later:

  • Reduced interest costs while your funds sit in the offset
  • Full access to your savings whenever you need them
  • Greater flexibility if the property becomes an investment down the track
  • Simpler loan and tax record keeping

The Key Takeaway

If there’s any chance you’ll keep your current home as an investment property one day, think carefully before using redraw. The redraw vs offset decision you make now could shape both your future borrowing strategy and your tax outcomes, and once a loan becomes mixed-purpose, it’s difficult to undo.

None of this means redraw is bad. For a home you’ll never rent out, it’s a perfectly good feature. The point is simply to match the structure to your plans, and if investing is even a possibility, an offset often keeps your options open in a way redraw can’t.

Frequently Asked Questions

What’s the difference between redraw and offset?

Not always. If you’ll never turn your home into an investment, redraw is a fine feature. In the redraw vs offset comparison, offset tends to be preferred.


Why can redraw affect my tax if I rent out my home later?

Under ATO Taxation Ruling TR 2000/2, each redraw is treated as new borrowing, and its deductibility depends on how you use the funds at that time. If you redrew for personal use, that portion isn’t deductible even after the property becomes a rental, creating a mixed-purpose loan.


Is an offset account always better than redraw?

Not always. If you’ll never turn your home into an investment, redraw is a fine feature. Offset tends to be preferred by those who might invest later, because it preserves the loan’s purpose and future deductibility.


What is a mixed-purpose loan?

It’s a loan where the borrowed funds have been used for both deductible (investment) and non-deductible (personal) purposes. The interest then has to be apportioned between the two, which is complex to track and can reduce your deductions.


Can I fix a loan that’s already mixed-purpose?

It’s difficult, and depends on your circumstances. This is really a question for your accountant, and it’s far easier to structure things correctly from the start than to untangle a mixed-purpose loan later.
