Beyond the Balance Sheet: ATO Tax Debt vs. Commercial Working Capital for Australian SMEs

For Australian small and medium-sized enterprises (SMEs), cash flow can make the difference between keeping a business running and struggling to meet everyday obligations. Even a profitable business can run short on cash when customers delay payments, operating expenses increase, or unexpected costs arise (Australian Government, n.d.-b). When tax payments become difficult to manage, business owners must decide whether to arrange a payment plan with the Australian Taxation Office (ATO) or use commercial finance to settle the debt.

Both options can provide relief, but they work differently. The better choice depends on the business’s financial position, how quickly it can recover, and whether it can manage the cost of repayment.

The Risks of Leaving Tax Debt Unpaid

Delaying tax payments may seem like a practical short-term solution, especially when cash is needed for payroll, suppliers, and other operating expenses. However, unpaid tax can become more expensive over time.

The ATO applies a General Interest Charge (GIC) to overdue tax, calculated daily and compounded. GIC incurred on or after 1 July 2025 can no longer be claimed as a tax deduction, which increases the real cost of carrying tax debt (Australian Taxation Office, 2026).

There can also be consequences for the business’s credit standing. The ATO may report business tax debts of $100,000 or more to credit reporting bureaus when certain conditions are met, including the debt being more than 90 days overdue and the business not keeping to a payment plan. Directors may also become personally liable for certain unpaid amounts, such as PAYG withholding, GST and super guarantee, through Director Penalty Notices (Australian Taxation Office, 2024; Australian Taxation Office, n.d.-c).

This means tax debt is not simply an outstanding balance. If left unmanaged, it can affect a company’s ability to secure finance, maintain supplier relationships, and protect its financial position.

Option 1: An ATO Payment Plan

An ATO payment plan allows a business to repay its tax debt in instalments rather than paying the entire amount upfront. It can be a practical option when the cash flow problem is temporary, such as when the business is waiting for a major customer to settle an invoice.

The main advantage is that the business can manage its existing liability without taking out another loan. A plan the business keeps to also counts as working with the ATO, so the debt is not reported to credit reporting bureaus (Australian Taxation Office, n.d.-a). However, GIC continues to accrue, and the business must still lodge and pay new tax obligations on time, including future Business Activity Statement (BAS) liabilities and PAYG withholding. If the plan defaults, the full overdue balance can become payable straight away (Australian Taxation Office, n.d.-b).

A payment plan works best when the business has a realistic recovery plan and can afford both its agreed instalments and its ongoing expenses. Otherwise, it may simply postpone the problem.

Option 2: Commercial Working Capital

A commercial working capital facility allows a business to borrow money to pay its ATO debt in full, replacing the tax liability with a commercial loan.

This can be useful when the business needs to settle a substantial tax balance and would benefit from spreading repayments over a longer period. Depending on the lender, the facility may offer a structured repayment schedule that makes it easier to forecast cash flow and budget for operating expenses.

However, refinancing does not eliminate the debt. The business must still repay the loan, including interest and any fees, and the total cost can be higher than the GIC it replaces. Lenders may also ask for security or a director’s guarantee, so the personal risk does not disappear; it changes form. The business must also continue meeting future tax obligations. Before borrowing, management should assess projected income, operating expenses, repayment commitments, and the total cost of the finance (Australian Government, n.d.-a).

Paying the debt in full does bring benefits beyond the balance itself. Once it is paid, the ATO has any listing removed from the business’s credit report, and paying the company’s debt in full also remits director penalties for that debt (Australian Taxation Office, n.d.-a; Australian Taxation Office, n.d.-c). The trade-off is that the business now owes a lender instead, on the lender’s terms.

Which Option Makes More Sense?

An ATO payment plan may be more appropriate for a business experiencing a temporary cash flow shortage with a clear path to recovery. Commercial finance may be worth considering when immediate settlement is necessary and the business can comfortably support the new repayments.

The key is to compare the total cost and risks of both options rather than focusing only on the interest rate. Your accountant is the best person to start that conversation with.

The Bottom Line

Choosing between an ATO payment plan and commercial working capital is ultimately a decision about managing risk and protecting the business’s long-term financial health.

An ATO arrangement can provide breathing room when a cash flow problem is temporary. Commercial finance can offer another route when a business needs to settle its tax debt immediately and has the capacity to repay the loan.

Neither option is automatically better. What matters is whether the business can meet its current obligations without creating another financial problem down the line.

The goal is not just to clear today’s tax debt. It is to put the business in a position where it can meet tomorrow’s obligations without relying on another financial arrangement to stay afloat.
