Should you use your home loan redraw or offset savings for the business?

It’s one of the most natural thoughts in small business. A supplier wants paying, a fit-out quote has landed, or a quiet month has left a gap, and you remember the home loan is $60,000 ahead. “Why borrow anything? I’ll just pull it back out.”

Sometimes that really is the sensible answer. But redraw money and offset money aren’t the same thing, and neither is free. One changes the tax character of your home loan. The other quietly spends the family’s safety net. Here’s how to think it through before you click “transfer”.

Redraw and offset: what are you actually using?

They look alike in your banking app. They behave very differently underneath.

• Redraw is extra money you’ve paid into the loan itself. Taking it out means borrowing it again. Your loan balance goes back up.
• Offset is a separate transaction account linked to the loan. The balance reduces the interest you’re charged, but it’s still your savings. Taking it out means spending your own money, and your loan balance doesn’t change, though the interest you pay goes up.

That one distinction drives almost everything else in this decision.

What does the ATO say about redrawing for business?

The ATO’s ruling on these facilities, TR 2000/2, treats a redraw as a fresh borrowing. Whether the interest on it is deductible depends on what the redrawn money is used for, not on the loan’s original purpose or the property behind it.

So if you redraw $50,000 from your home loan and put it into the business, that slice of the loan may now have a business purpose. The rest of the loan is still private. You now have a mixed-purpose loan, and the interest has to be split between the two.

That split isn’t a one-off sum. The ATO’s guidance on interest expenses explains that when one loan covers both private and income-producing purposes, repayments have to be apportioned across both portions for the life of the loan. Every repayment you make reduces both parts, which can shrink the deductible slice faster than you’d like. Add a second redraw for a family holiday or a car, and the arithmetic gets messy quickly.

None of this means redrawing for business is wrong. It means it’s a tax decision as much as a cash one, and it’s much easier to get right before the money moves than to untangle afterwards. It’s a good one to add to your list of questions for your accountant.

Is your lender even happy for you to do it?

Check this first. Redraw is a feature of a home loan, and lenders set the rules for it. At least one major bank’s published redraw terms list using redraw “for business purposes” as a situation where redraw isn’t available. Other lenders are more relaxed, and loans held in a company or trust can have their own process.

Lenders can also limit or suspend redraw under their terms, for example if the loan falls behind. If the business plan relies on redraw being there next month, that’s worth knowing now.

The simplest step: read your loan terms, or ask the lender in writing whether business use of redraw is allowed on your particular loan.

What about just spending the offset savings?

Offset money feels like the cleanest option. No new borrowing, no forms, no lender to ask. And for a modest, short-term need, using your own cash can be perfectly sensible.

Two things to weigh first:

1. The interest on your home loan generally stays private. Because you’re spending savings rather than borrowing, taking money out of the offset doesn’t turn any of the home loan interest into a business expense. Your loan costs more each month, with no tax offset for it.
2. It’s usually the family’s only buffer. For many owners, the offset balance is the emergency fund. Spend it on the business and the household is left with little cash for the mortgage, school costs or a surprise. The risk has moved from the business to the family, without anyone quite deciding that.

If you’d struggle to rebuild the offset within a few months, treat that as a warning sign rather than a convenience.

So which option fits which situation?

Option	Can make sense when	Think again if
Offset savings	The amount is small, you’ll rebuild it within months, and the household keeps a healthy buffer afterwards	It would leave the family with little or no emergency cash
Redraw	Your lender allows business use, your accountant is comfortable with the mixed-purpose loan, and the amount is modest and short-term	Your loan terms exclude business use, or you’ll redraw again for private costs
Separate business-purpose second mortgage	The need is larger or longer, you want the business debt kept apart from the home loan, and there’s a clear exit	The business can’t show how it repays, or the purpose is vague
Unsecured or line-of-credit facility	The business is trading with steady bank statements and you’d rather keep property out of it	The amount needed is beyond what turnover supports
Not borrowing at all	Better debtor collection, supplier terms or timing can close the gap	The gap keeps recurring, which may point to a pricing or margin problem

If a recurring, up-and-down need is the real issue, our page on a business line of credit versus a second mortgage is worth a read. And if you’re weighing a bigger restructure of the home loan itself, see refinancing the home loan or adding a second mortgage.

Why do some owners keep business debt in a separate loan?

Not because a separate loan is always better. It isn’t. But it does three useful things:

• A clean purpose. Every dollar has one job. Your accountant can see exactly what was borrowed and why, and the home loan stays a home loan.
• A clean exit. A separate loan can be paid out from the thing that justifies it, such as a contract’s progress payments, a seasonal stock sell-through or the sale of an asset, without tangling with your home loan repayments. Our exit plan guide walks through how to build that before you sign.
• A protected buffer. Your offset stays where it is, doing its real job as the family’s safety net.

The trade-off is that it’s another loan against the property, with its own costs, documents and a lender’s assessment. That’s worth it for a meaningful, defined business need. It’s rarely worth it for a $10,000 gap you’ll close in six weeks.

A worked example (illustrative only)

Priya runs a small physiotherapy clinic and owns a home worth about $1,000,000. The home loan balance is $420,000, with $70,000 sitting in the offset account and $30,000 of redraw available. The clinic needs $80,000 to fit out a second treatment room and buy equipment.

Option A: use the offset and redraw. Priya could take $50,000 from the offset and redraw $30,000. Total debt against the home becomes $450,000, or about 45% of the property’s value. Sounds fine on paper. But the household’s cash drops from $70,000 to $20,000, the home loan is now part private, part business, and Priya’s lender’s terms turn out not to allow redraw for business purposes anyway.

Option B: a separate business-purpose loan. Priya keeps the offset intact and borrows $80,000 secured on the home for the fit-out. Combined debt is $500,000, or about 50% of the property’s value. That’s comfortably inside a 70% combined LVR band, which would allow about $700,000, so there’s a cushion of roughly $200,000. The household keeps $70,000 in cash, and the business debt sits in its own loan with its own exit: repayment from the second room’s appointment income, with a refinance into an unsecured facility once the clinic has more trading history.

Option C: a blend. Priya uses $20,000 of offset money for the smaller equipment items she can rebuild quickly, and borrows $60,000 separately for the fit-out.

There’s no single right answer here. Option A uses less borrowing overall, but costs the family its buffer and runs into the lender’s terms. Option B costs more to set up but protects the household and keeps the books tidy. The point is that Priya chose on purpose, rather than defaulting to whatever was easiest to click.

Five questions before you touch redraw or offset

1. Does my lender allow business use of redraw on this loan? Get the answer in writing.
2. Has my accountant looked at the tax effect? Especially if the loan already has mixed purposes.
3. What buffer will the household have left afterwards? In months of living costs, not dollars.
4. How and when does this money come back? If you can’t say, that’s the first thing to fix.
5. Does everyone on the home loan know? A redraw on a joint loan affects both borrowers. Our page on protecting the family home has a gentle way to start that conversation.

Your home loan has a job. Let’s see if the business needs its own funding

Reaching for your own redraw or offset is a sensible instinct. It shows you’d rather use what you have than take on new debt. Often, for small and short-lived gaps, that’s exactly right. But when the amount is meaningful, or the business need will run for a while, keeping the family’s money and the business’s borrowing apart tends to be the calmer path.

That’s where we can help. Tell us about the property, the home loan and what the business needs, and a real person will look at your whole picture and call you to talk it through. If the honest answer is “use your offset and keep it simple”, you’ll hear that. Asking takes about a minute, and your credit file stays untouched when you first enquire. Nothing is checked unless you decide to go ahead. Your enquiry stays with one specialist and isn’t passed around to a crowd of lenders, so your phone won’t light up with strangers.

Please fill in the form accurately: the property’s value, what’s owing (including any redraw already used), who’s on the title, how much the business needs, what for, and how you’d repay it. Business purposes only.
