An unpaid ATO tax debt is one of the few business liabilities that gets more expensive every single day. Interest compounds daily, it is no longer tax deductible, and once a debt passes certain thresholds it can appear on your commercial credit file where lenders, suppliers and insurers can see it.
Many Australian business owners deal with this using an ATO payment plan. Others use a business loan to pay the debt out in full and repay the lender instead. Both are legitimate approaches, and the right one depends on the size of the debt, your cashflow and what the debt is currently costing you.
This guide explains how ATO tax debt funding works, what the debt actually costs while it sits unpaid, and how to decide between a payment plan and external finance.
Quick Answer
An ATO tax debt loan is a business loan used to pay out an overdue tax debt in full, so the business repays a lender on agreed terms instead of carrying a compounding ATO balance. It is generally worth considering when the tax debt is holding up finance approvals or supplier credit, when the ATO general interest charge is higher than the cost of borrowing on an after-tax basis, or when the ATO will not agree to a payment plan the business can realistically afford.
An ATO payment plan is usually the cheaper first option for smaller, recent debts where the business can clear the balance quickly. External finance becomes more compelling as the debt gets older, larger, or starts to block other funding.
What Is an ATO Tax Debt Loan?
An ATO tax debt loan is not a special product offered by the ATO. It is a business loan where the stated purpose of the funding is to pay a tax liability.
The funds are used to pay out overdue amounts such as income tax, GST reported on a BAS, PAYG withholding, PAYG instalments or superannuation guarantee charge. The business then makes repayments to the lender under the loan agreement.
Tax debt funding can be structured in several ways depending on the amount required and the security available:
- An unsecured business loan repaid over a fixed term
- A secured business loan using property or business assets
- A business line of credit drawn as needed
- Invoice finance, where funding is advanced against unpaid customer invoices
- A short-term working capital facility to bridge a single quarter
Because many businesses need tax debt funding before their latest financials are finalised, these applications are often assessed on a low doc basis using recent bank statements and trading history rather than full accountant-prepared reports.
What an Unpaid Tax Debt Actually Costs
This is the part most business owners underestimate. The ATO applies the general interest charge (GIC) to overdue tax, and it is calculated daily on a compounding basis.
Two features make GIC more expensive than a headline percentage suggests. First, daily compounding means interest accrues on previously accrued interest. Second, and more significantly, GIC incurred on or after 1 July 2025 can no longer be claimed as a tax deduction. The same rule applies to the shortfall interest charge.
| ATO interest charge | Annual rate (quarter commencing 1 July 2026) | How it is applied | Deductible? |
|---|---|---|---|
| General interest charge (GIC) | 11.43% p.a. | Daily compounding on any overdue tax balance | No, for amounts incurred on or after 1 July 2025 |
| Shortfall interest charge (SIC) | 7.43% p.a. | Daily compounding on a shortfall from an amended assessment | No, for amounts incurred on or after 1 July 2025 |
The ATO reviews the GIC rate every quarter, with the next quarter’s rate usually announced around two weeks before it starts. Always check the current rate on the ATO website before making a decision.
A Simple Illustration
Take a $50,000 tax debt at a GIC rate of 11.43% per annum, compounding daily.
- Left unpaid for 12 months with no repayments, the balance grows to roughly $56,050. That is around $6,050 in non-deductible interest.
- Paid down in equal monthly instalments over 12 months, the interest cost is roughly $3,150, still non-deductible.
These figures are illustrative only and exclude any upfront payment the ATO may require, any penalties, and any change in the GIC rate during the period. They are included to show the shape of the cost, not to provide a quote. The ATO publishes a payment plan estimator that will calculate figures for your specific debt.
The key comparison is not the loan rate versus the GIC rate in isolation. Where interest on a business loan is deductible because the borrowing is for business purposes, and GIC is not, the effective after-tax gap can be wider than the two headline rates suggest. Whether the interest on any particular loan is deductible depends on your circumstances, so confirm this with your accountant or registered tax agent before relying on it.
When Tax Debt Starts Affecting Your Credit File
Under the Disclosure of Business Tax Debts measure, the ATO may report a business tax debt to credit reporting bureaus where all of the following apply:
- The business has an ABN and is not an excluded entity
- At least $100,000 of tax debt is overdue by more than 90 days
- The business is not engaging with the ATO to manage the debt
- There is no active complaint with the Tax Ombudsman about the intent to report
The third criterion is the important one, because it is entirely within the business’s control. The ATO has stated it will not report a debt where the business is effectively engaging with it, even where the balance is $100,000 or more. Before any disclosure occurs, the ATO issues a formal notice of intent to disclose, which gives the business 28 days to act.
This matters commercially because a disclosed tax default sits on the commercial credit file that banks, equipment financiers, trade insurers and suppliers review. The practical consequences can include declined finance applications, reduced supplier credit limits, tighter trading terms or a shift to cash-on-delivery arrangements.
Disclosure is not the only escalation available to the ATO. Depending on the circumstances, the ATO may also issue garnishee notices to redirect funds owed to the business, issue director penalty notices that can make directors personally liable for unpaid PAYG withholding, net GST and superannuation guarantee charge, or commence recovery action through the courts.
ATO Payment Plan Vs. Tax Debt Loan
Most businesses with an overdue tax debt are choosing between these two paths, or using a combination of both.
| Consideration | ATO Payment Plan | Tax Debt Loan |
|---|---|---|
| Cost of interest | GIC applies to the outstanding balance and continues to accrue for the life of the plan | Interest and fees are charged by the lender under the loan agreement |
| Tax treatment of interest | GIC incurred on or after 1 July 2025 is not deductible | Interest on borrowings for business purposes is generally deductible, subject to your circumstances |
| Setup | Businesses owing $200,000 or less may be able to set up a plan through ATO online services or the self-help phone line. Larger or more complex debts require direct negotiation | Application through a lender or broker, assessed on revenue, cashflow, trading history and security |
| Effect on ATO position | A plan being complied with is generally treated as effective engagement, which helps avoid credit reporting | The debt is paid out, so the ATO liability is removed entirely |
| Effect on credit file | The tax debt is not reported while the plan is on track, but the liability remains on the balance sheet | The ATO liability is cleared, though the new loan is a commercial debt that other lenders will consider |
| Flexibility | Plans are commonly set over shorter periods and the ATO assesses affordability case by case. Missing payments can default the plan | Terms are negotiated with the lender and may extend longer than the ATO would allow |
| Risk if it goes wrong | A defaulted plan can make the full remaining balance immediately payable and reopen escalation | Default is a breach of the loan agreement, and any security provided is at risk |
One point worth being clear about: a payment plan does not pause GIC. Interest continues to accrue at the full rate on the outstanding balance for the entire life of the plan. A longer plan means more non-deductible interest.
Some small businesses may also be eligible for an interest-free payment plan for certain overdue activity statement amounts, subject to ATO turnover and debt thresholds and keeping the plan on track. Where a business qualifies for this, it is usually the cheapest option available and should be assessed first.
When a Tax Debt Loan May Be Worth Considering
External finance is not automatically the better answer. It tends to make the most sense in these situations:
- The tax debt is blocking a finance approval, a lease, a tender or a supplier credit application
- A notice of intent to disclose has been received and the debt needs to be resolved inside 28 days
- The ATO will not agree to a repayment period the business can actually afford
- A previous payment plan has defaulted, making a new plan harder to negotiate
- The debt is large enough that the non-deductible GIC cost outweighs the cost of deductible borrowing
- The business needs a longer repayment runway than the ATO typically permits
- Multiple separate tax accounts need consolidating into one repayment
When an ATO Payment Plan Is Likely the Better Option
A payment plan is often the stronger choice where:
- The debt is relatively small and can be cleared within a few months
- The business qualifies for an interest-free activity statement plan
- Lodgements are up to date and there is no history of defaulted plans
- Cashflow is timing-related rather than structural, for example a large receivable landing next month
- The business does not want to add a commercial debt to its balance sheet
There is also a middle path. Some businesses use a payment plan to stabilise the ATO position immediately, then arrange working capital funding to clear the balance faster and reduce total non-deductible interest.
Can You Get Business Finance With an Existing Tax Debt?
Yes, in many cases. A tax debt does not automatically disqualify a business from finance, but it does change how lenders assess the application.
Lenders will generally want to understand:
- The size of the debt relative to annual revenue
- How long the debt has been outstanding
- Which tax types make up the balance, with unpaid PAYG withholding and superannuation usually viewed more seriously
- Whether lodgements are up to date
- Whether a payment plan exists and is being complied with
- Whether the debt has been disclosed to credit reporting bureaus
- Recent trading performance and cashflow through bank statements
One practical point that often gets missed: outstanding lodgements are frequently a bigger obstacle than the debt itself. A business with an ATO balance but current lodgements is generally easier to assess than one with unlodged BAS or overdue returns, because no lender or tax agent can accurately size a liability that has not been reported yet. Bringing lodgements up to date is usually the first step worth taking.
A Practical Sequence for Dealing With Tax Debt
- Confirm the exact balance for each tax account through ATO online services rather than working from an estimate
- Bring any outstanding lodgements up to date so the full liability is known
- Check whether the business qualifies for an interest-free activity statement payment plan
- Engage with the ATO promptly, particularly if a notice of intent to disclose has arrived, as the 28-day window is short
- Use the ATO payment plan estimator to calculate the real interest cost of the plan you are considering
- Compare that cost against funding options on an after-tax basis with your accountant
- Address the underlying cause, whether that is tax not being set aside, margin pressure or slow debtor collection
That last step matters most. Funding a tax debt without fixing the reason it accumulated tends to produce the same problem again next quarter, with a loan repayment now sitting alongside it.
