Quick answer: Do not empty the operating account simply to reduce the ATO balance if doing so leaves the business unable to meet wages, suppliers or current tax. Model the minimum operating cash buffer first, then decide how much cash can safely reduce the ATO debt and whether finance should replace part of the liquidity.
This is a capital-allocation decision. Paying the ATO faster reduces the debt and future GIC, but cash used for tax is no longer available for payroll, stock or supplier commitments. The wrong decision can turn a manageable tax problem into an operating cash-flow problem.

Worked example: do not compare the ATO balance in isolation
Illustrative only.
| Item | Illustration |
|---|---|
| Cash available today | $80,000 |
| ATO debt | $120,000 |
| Near-term stock / supplier need | $45,000 |
| Payroll + fixed-cost buffer | $30,000 |
| Cash apparently available for ATO after buffer | $5,000 |
| Decision point | A larger ATO payment may require replacement working capital almost immediately |
Calculate the operating cash floor first
Start with the next eight to twelve weeks of committed cash outflows: payroll, rent, suppliers, insurance, GST/PAYG, equipment repayments and any seasonal stock purchases. The business should know the minimum cash balance it needs before deciding what is genuinely “spare”.
Compare the economic value of the working capital
If $40,000 of stock reliably produces margin and turns quickly, preserving that liquidity can be economically different from holding idle cash. But projected sales are not the same as collected cash, so use conservative timing.
The same logic applies to payroll or project costs that must be funded before customer receipts arrive.
Do not finance an unresolved tax leak
If new BAS, PAYG or income-tax liabilities are still not being provisioned, another facility can simply postpone the problem. The business needs a plan for both the historic ATO balance and current tax.
Structures worth comparing
Partial cash payment to the ATO while retaining a minimum buffer.
ATO payment plan plus a separate working-capital facility.
Full ATO refinance where the replacement repayment materially improves cash flow.
Receivables or invoice finance where the real problem is customer payment timing rather than the tax debt itself.
What to do next
If the business has to choose between paying the ATO and funding operations, request a working-capital assessment before making a formal lender application.
Frequently asked questions
Should I use all available cash to pay the ATO?
Not automatically. First calculate the minimum cash buffer required to keep trading and meet current obligations.
Can I keep an ATO plan and borrow for working capital?
Potentially. The lender will still assess the ATO liability and both repayment commitments.
Is refinancing the ATO always the best working-capital solution?
No. Sometimes the better structure is to keep the plan and finance the underlying cash-conversion gap.
What should I bring to the assessment?
ATO statements, the payment-plan schedule, recent bank statements, aged receivables/payables where relevant, and a short cash-flow forecast.
