Tax Debt Loans: Clearing Your ATO Debt the Right Way

An ATO debt rarely arrives all at once. It usually builds over a few quarters: a BAS that couldn't be paid in full, a tax bill bigger than expected after a strong year, or cash that went into stock and staff before the assessment landed. By the time the letters start arriving, the general interest charge has been compounding for months.

A tax debt loan pays the ATO in full and replaces the debt with a loan on terms you agree with a lender. The interest charge stops the day the account is cleared, and you repay the lender on a schedule built around your cash flow. For a viable business that has hit a timing problem, that can be the cleanest way back to a clear ATO account.

It isn't always the right answer, though. If the business is still losing money, a loan just swaps one creditor for another. That's why Causbrooks Finance starts every tax debt conversation alongside Causbrooks Chartered Accountants. Before anyone talks about lenders, we confirm what is actually owed, why it built up, and whether borrowing will genuinely help.

This guide explains how tax debt loans work, how they compare with an ATO payment plan, when they make sense and when they don't, and what lenders look for.

What is a tax debt loan?

A tax debt loan is business finance used to pay an ATO debt in one lump sum. The debt might be income tax, activity statement amounts such as GST and PAYG withholding, or the Superannuation Guarantee Charge. Once the lender pays the ATO, the business owes the lender instead, on a fixed repayment schedule.

The term describes what the money is for rather than a particular product. Depending on the size of the debt and the security available, it could be an unsecured business loan, a loan secured against property, a line of credit or invoice finance. Each comes with different costs, terms and approval requirements, so the structure matters as much as the decision to borrow.

Why an ATO debt now costs more to carry

Overdue tax attracts the ATO's general interest charge, or GIC. It accrues daily and compounds, and the rate is reset each quarter at a margin above the short-term bank bill rate. That puts it well above what many lenders charge for secured business lending.

Until recently, businesses could at least claim a deduction for GIC, which softened the blow. That has now changed. Under the Treasury Laws Amendment (Tax Incentives and Integrity) Act 2025, GIC and shortfall interest charge incurred on or after 1 July 2025 are no longer deductible, even where the underlying debt relates to an earlier year (ATO). A business carrying a tax debt now pays the full GIC out of after-tax profit.

The ATO has also been much more active in chasing debts since the pandemic, with more direct contact, more director penalty notices and, for persistent debts, garnishee notices and other recovery action. For most owners, the time and stress of dealing with the ATO is a cost in itself.

Start with the accounts, not the loan

A tax debt is an accounting problem before it is a finance problem. Borrowing to pay the ATO only works if three questions are answered first: how much is really owed, why it built up, and whether the business can carry a loan from here.

The true balance is often unclear. Returns or activity statements may be outstanding, estimates may be sitting on the account, or amounts may be split across income tax, GST, PAYG withholding and super guarantee. Until lodgements are current, nobody knows the real number, and lenders won't either.

The cause matters just as much. PAYG instalments set too low, GST collected and then spent, or growth that outran cash will keep producing new debts if they aren't fixed. Clearing the balance with a loan while the cause is still there just resets the clock.

Because Causbrooks Finance works alongside Causbrooks Chartered Accountants, these questions are answered before we approach a lender. Your accountant brings lodgements up to date, confirms the balance and checks the business is viable. We then find the right lender and structure, and share the proposed loan with your accountant before you sign. If you have a different accountant, we'll work with them in the same way.

Tax debt loan or ATO payment plan?

The main alternative to borrowing is a payment plan with the ATO. Smaller debts can often be set up through ATO online services, while larger debts need to be negotiated with the ATO directly. A plan is quick, costs nothing to arrange and doesn't involve a lender, which makes it the right first step for many businesses. The catch is that GIC keeps accruing on the balance, and if instalments are missed the plan can default, making the full overdue amount payable immediately (ATO).

Neither option wins every time. A short plan for a modest debt the business can clear within a year may be cheaper and simpler than a loan. A larger debt, one that needs several years to repay, or one that is blocking other finance, often suits a loan better. Your accountant can model both against your cash flow so you're comparing real numbers.

When a tax debt loan makes sense

A loan works best when the business is sound and the debt is a timing problem rather than a symptom of something deeper. Common examples are a business that grew fast and spent cash on stock, staff or equipment before the tax bill arrived, a business that had one bad year and has since recovered, and a business hit with a large one-off assessment after an asset sale or an ATO review.

The numbers need to stack up too. If the loan's rate, after any deduction the business is entitled to, is lower than the non-deductible GIC, every month the loan replaces the ATO debt saves money. That is most often true when the loan can be secured against property.

Clearing the ATO can also open other doors. Many lenders won't approve equipment finance, a commercial loan or a refinance while a tax debt is outstanding, so paying the ATO can be the first step towards the finance the business needs to grow. For directors, paying amounts that could otherwise become personal liabilities removes a serious risk.

When a tax debt loan isn't the answer

A loan doesn't make a tax debt disappear; it changes who you owe. If the business is losing money with no clear path back to profit, or the ATO balance grows every quarter because current obligations aren't being met, borrowing adds repayments to a business that already can't meet its commitments. Secured against the family home, that can turn a business problem into a personal one.

The warning signs are a debt that keeps rising despite a payment plan, returns and BAS left unlodged because the numbers are uncomfortable, and suppliers or staff also going unpaid. If those sound familiar, the right first step is a frank conversation with your accountant, not a loan application.

There are other options for businesses in genuine difficulty. Eligible incorporated businesses can use the small business restructuring process to put a plan to creditors, including the ATO, while the directors stay in control. Free, independent help is also available from the National Debt Helpline and small business financial counsellors. We will always tell you if we think a loan isn't the right answer.

Types of tax debt loan

The right loan depends on how big the debt is, how quickly the ATO needs to be paid, what security is available and how long the business needs to repay.

Unsecured business loans

Unsecured loans are the quickest option and don't need property as security, although lenders usually ask the directors for a personal guarantee. They suit smaller debts that can be repaid over a relatively short term, often up to a few years. Rates are considerably higher than for secured loans, so the comparison with GIC needs care.

Loans secured by property

Where the owners have equity in residential or commercial property, a secured loan usually offers the lowest rate and the longest term. It can be the most cost-effective way to clear a large debt, but the property is at risk if repayments can't be met, so it only suits a business that is clearly viable. Approval takes longer because of valuations and legal documents.

Lines of credit and overdrafts

A line of credit lets the business draw what it needs and pay interest only on what it uses. It can suit a tax debt that is part of a wider cash flow squeeze, because the same facility can absorb seasonal swings. The discipline lies in paying it down rather than letting it become permanent debt.

Invoice finance

Businesses with a large debtor book can use invoice finance to release cash tied up in unpaid invoices and pay the ATO from that. Because the facility grows with sales, it can also help prevent the cash gap that caused the tax debt in the first place.

How lenders look at a business with an ATO debt

A tax debt doesn't rule out finance, but lenders will look more closely. The first question most will ask is whether every tax return and activity statement is lodged. Unlodged returns worry lenders more than the debt itself, because they mean no one knows the true balance. Bringing lodgements up to date before applying is usually the single most useful thing a business can do.

Lenders will also look at the size and type of the debt, how long it has been building, and how any payment plan has gone. A plan that has been met consistently shows the business can handle repayments. A defaulted plan, or a string of them, raises questions. They will also ask whether any director penalty notices have been issued and whether the ATO has started recovery action.

Beyond that, the assessment looks like any other business loan: trading history, recent financial statements or BAS, bank statements, existing debts and available security. Specialist and non-bank lenders are generally more comfortable with tax debts than the major banks, which is where knowing each lender's policy makes the difference. When your accountant has prepared the figures, the application usually tells a clearer story.

Director penalty notices and unpaid super

Some tax debts reach beyond the company. Under the director penalty regime, directors can become personally liable for a company's unpaid PAYG withholding, GST and Superannuation Guarantee Charge. The ATO enforces this by issuing a director penalty notice.

Timing is critical. Where these amounts were reported to the ATO on time, directors generally have more options for dealing with a notice. Where they weren't reported within the required timeframes, the options narrow sharply and the liability can stay with the director whatever happens to the company. It's one of the strongest reasons to keep lodging activity statements on time even when the business can't pay.

Unpaid super deserves particular attention. It affects employees directly, attracts its own charges and is a priority for the ATO. Using a loan to clear PAYG withholding, GST and super guarantee amounts removes a personal risk for directors as well as a business debt. Director penalties are complex, so if you've received a notice or think you may be exposed, speak to your accountant or a lawyer before doing anything else.

How Causbrooks Finance arranges a tax debt loan

Preparation makes the biggest difference to how quickly the ATO gets paid.

1. Review the position with your accountant. Confirm the full amount owed, which ATO accounts it sits in, why it built up, and whether borrowing is the right move.
2. Bring lodgements up to date. Any outstanding returns and activity statements are lodged so the debt is final. Lenders will usually insist on this.
3. Get a current ATO statement. This shows the exact balance including GIC, and any payment plan in place.
4. Compare lenders. We compare lenders that accept tax debts, recommend the loan type and structure, and set out the total cost against staying on a payment plan.
5. Check the structure with your accountant. The proposed loan and repayments are reviewed against your cash flow and tax position before you sign.
6. Apply and get approved. We lodge the application with your financials, BAS, bank statements and ATO statement, and handle the lender's questions.
7. The lender pays the ATO. In most cases the lender pays the ATO directly using your payment reference, so the money goes exactly where it should.
8. Confirm the account is clear and stay current. Your accountant checks the ATO account shows a nil balance and any payment plan is closed, then helps keep future lodgements and payments on track.

The last step is the one most often skipped. A loan clears today's debt; staying current with the ATO is what stops the business needing another one.
