Paying tax debt with a business loan: the honest pros and cons

Borrowing to pay the tax office sounds like robbing Peter to pay Paul. Sometimes it is. Other times it’s the cheapest, calmest way out of a debt that’s about to get much more expensive and much more public. The difference comes down to a handful of things you can check this week: what the debt is made of, what the ATO is about to do next, what security the lender wants and whether the business can carry the repayments alongside its next BAS.

This guide sets out the genuine advantages and the genuine risks, then shows how the same tax bill can lead two owners to opposite answers.

The scorecard at a glance

Pros	Cons
Stops ATO escalation: garnishees, director penalty notices, bureau reporting	Swaps an unsecured creditor for one that may hold your property
Loan interest is generally deductible for business borrowing; ATO interest from 1 July 2025 isn’t	Establishment, valuation and legal costs arrive upfront
Repayments can be spread over a longer, fixed term	A lender runs a credit check; the ATO doesn’t for a plan
One payment to manage instead of stacked ATO instalments plus new BAS	Doesn’t fix whatever caused the debt in the first place
Clears the way for refunds that the ATO would otherwise offset against the debt	A daily or weekly debit can starve next quarter’s GST

Neither column wins automatically. Each row carries different weight depending on the size of the debt and how far the ATO has already moved.

The case for borrowing

The after-tax arithmetic has shifted

For a long time, the go-to advice was simple: the ATO is the cheapest lender you’ll ever have, so take a payment plan. Part of the logic was that the general interest charge could be claimed back at tax time. That stopped for GIC and shortfall interest incurred on or after 1 July 2025. The charge still compounds daily on the unpaid balance, and every dollar of it is now a true after-tax cost.

A commercial loan works the other way. Interest on money borrowed for the business is generally deductible, so the real cost is the headline cost less the tax saving. Whether that holds for a loan that pays a particular tax depends on your entity and what the tax relates to, so get your accountant to confirm it in writing. Even so, the comparison is now closer than most owners assume, especially for a bank facility or a property-secured loan held for a few months.

The ATO debt calculator gives you the plan side in dollars. Ask any lender for the total repayable, including fees, for the loan side.

It switches off the escalation ladder

The ATO’s firmer actions run roughly in sequence: reminder letters, a phone call, then tools with real teeth. A garnishee notice can redirect money from your bank account or your customers. A director penalty notice can make directors personally liable for certain company debts. And once overdue business tax reaches $100,000 for more than 90 days without engagement, the ATO can report it to commercial credit bureaus.

A cleared account takes all of that off the table in one move. When a garnishee is already in place or a DPN has arrived, that speed is often worth more than any saving on interest.

Repayments can be shaped to the business

ATO plans are usually built to clear the debt as quickly as you can manage, and the online self-serve option has limits. A lender can set a fixed term that matches how the business actually earns: monthly for a professional practice, a longer term for a larger property-secured amount, or a line you can redraw to cover the next seasonal dip. Smaller, predictable repayments make it less likely that a bad month causes a default.

Refunds stop disappearing

While a debt sits on your ATO account, refunds and credits, including GST refunds, are generally offset against it. Clearing the debt means a future refund reaches the business rather than vanishing into the old balance.

The case against borrowing

You might be putting the house behind a debt that didn’t need it

This is the con that matters most. The ATO is an unsecured creditor for ordinary business tax. It can pursue a company, garnishee accounts and use the director penalty regime, but it doesn’t hold a mortgage over your home. A second mortgage or caveat loan does. If the loan goes bad, the lender’s remedy is the property.

For a large, escalating debt with directors already exposed, that trade can still make sense. For a $30k BAS shortfall you could clear on a six-month plan, putting your home up as security is usually out of proportion. Read the risks of using your home as business security before you sign anything secured.

Money costs money upfront

A plan has no establishment fee. A loan usually does, and property-secured lending adds valuation and legal costs. On a modest debt repaid quickly, those fixed costs can outweigh the GIC you’d have saved. Short-term products priced on a factor rate can cost a lot more again if you repay early and the full charge still applies.

A lender looks at you more closely than the ATO does

Agreeing a plan with the ATO doesn’t involve a credit check. A lender will check credit, bank statements and, for larger amounts, financials or property. Each application adds an enquiry to your file, so apply once, to the right place, rather than to five lenders in a week.

The cause is still there

Tax debt is usually a symptom: GST spent as working capital, a customer who paid late, a big year followed by an unexpectedly large assessment. Pay the debt with a loan and do nothing else, and in three months you have the loan and a new BAS you can’t pay. That’s the worst of both worlds.

Which tax debts should a loan clear first?

Not every dollar on an ATO account carries the same risk. If you can only fund part of the debt, the order matters.

Debt	Can directors become personally liable?	Priority if funds are limited
PAYG withholding from wages	Yes, under the director penalty regime	High
GST	Yes, since 1 April 2020	High
Super guarantee charge	Yes	High
Company income tax	No, not under the director penalty regime	Lower, often suits a payment plan
PAYG instalments	No	Lower; consider varying future instalments

A common pattern is a loan that clears the withholding, GST and super amounts, with company income tax left on a modest plan. Talk it through with your accountant, because how the ATO applies a payment across your accounts can affect the result.

Directors who’ve already received a notice should read director penalty notice funding, because the timeframes are short.

Two owners, same debt, different answers

These are illustrative scenarios, not client cases.

A joinery company in Geelong owes $85k: $50k in GST and PAYG withholding across three activity statements, plus $35k in company income tax. All statements are lodged. Turnover is steady. The ATO has offered a plan, but the instalments would take most of the monthly surplus, and a GST refund on a new CNC machine is due soon and would otherwise be absorbed by the debt. The directors borrow $55k unsecured over two years, assessed on bank statements, to clear the GST and withholding. The company tax goes on a short ATO plan. The refund lands in the business account. Verdict: borrowing made sense, and no property was involved.

A home-based design consultancy owes $22k after an unexpectedly large assessment. Cash flow is lumpy but positive. A lender offers a caveat loan over the owner’s home to clear it. Fees would eat a meaningful chunk of the debt, and the owner’s family home would sit behind a business tax bill they could clear in eight months on a plan. Verdict: the plan wins. The owner also varies their PAYG instalments so next year’s bill doesn’t arrive in one lump.

Questions to answer before you borrow

1. What exactly is owed, and on which ATO accounts? Download the statements, not just the total.
2. Is everything lodged? Neither the ATO nor a reputable lender will move far while returns or statements are outstanding.
3. What has the ATO already done? A garnishee or DPN changes the urgency completely.
4. What would a plan cost in dollars, after tax? Then do the same for the loan, fees included.
5. What security is being asked for, and is it proportionate? An unsecured or equipment-backed option may exist for smaller amounts.
6. Can you carry the repayment plus the next BAS? Run both through a cash flow forecast for the next two quarters.
7. Will the lender pay the ATO directly? It’s tidy, and it gives you a clear record.

Clearing the ATO without trading one problem for another

A good tax debt loan leaves you with one manageable repayment, a clean ATO account and your home only on the line if that’s genuinely warranted. A bad one does the reverse. We look at tax debt enquiries every week and we’ll say plainly if a plan would serve you better than a loan.

Our form takes about a minute. Sending it doesn’t leave a mark on your credit file, and it isn’t fired off to a list of lenders who’ll all start ringing. One of our team reads the details and calls you back to talk it through. List the debt by type, which statements are lodged and any notices from the ATO; getting those right means the first option we put to you is the one that fits.
