tl;dr: Many SMEs accumulate significant tax liabilities through PAYG withholding, GST and super. The ATO has become one of the largest unsecured creditors for small businesses due to delayed payments, deferred pandemic‑era debts and increased enforcement. Rising insolvencies show that ignoring tax obligations can lead to business failure. This article explains how the ATO became such a large creditor and what businesses can do to avoid falling behind.
Pandemic legacy
During the COVID‑19 pandemic the ATO paused debt collection and allowed businesses to defer tax payments. Some businesses built up large liabilities that were never repaid. When pandemic support ended, the ATO resumed enforcement. The RBA notes that the removal of pandemic support and rising costs have contributed to a rise in insolvencies.
Components of ATO debt
- PAYG withholding: Employers must withhold tax from employee wages and remit it to the ATO. Delaying these payments effectively uses employees’ income tax as working capital.
- GST: Many businesses collect GST on sales but delay remitting it. Because GST is charged on revenue and credits are claimed on expenses, failure to lodge BAS on time can quickly build a debt.
- Super guarantee charge: Failing to pay super on time triggers the SGC, which includes interest and administration fees. The SGC was historically not tax deductible, but from 1 July 2026 it becomes deductible.
Why ATO debt grows
- Cash‑flow pressures: SMEs use withheld taxes to fund operations, especially when cashflow is tight. Without proper budgeting, PAYG and GST debts mount.
- Lack of separation: Business owners sometimes mix tax liabilities with general funds. The ATO recommends keeping separate accounts for GST, PAYG and super.
- Delayed lodgements: Failing to lodge BAS or SGC statements on time triggers lockdown DPNs and can lead to penalty interest.
- High interest: GIC rates are often higher than commercial loan rates. Interest compounds daily, causing debts to snowball.
- Disclosure: New laws allow the ATO to disclose significant tax debts to credit bureaus, which can restrict access to finance.
Avoiding the trap
- Lodge and pay on time: Even if you cannot pay in full, lodge on time to avoid lockdown DPNs.
- Set aside funds: Separate bank accounts for GST, PAYG and super create discipline.
- Monitor your accounts: Regularly check ATO portals for outstanding amounts.
- Seek finance early: Use working‑capital facilities to meet tax obligations when cashflow is tight. Refinancing tax debt can lower interest costs.
FAQs
Why does the ATO charge high interest? The GIC is designed to compensate the community for the time value of money and ensure fairness among taxpayers.
Can the ATO negotiate a debt compromise? In exceptional circumstances the ATO may agree to a compromise, writing off part of the debt. However, businesses must provide evidence of hardship and inability to pay.
Will the ATO publish my debt? If you owe more than a certain threshold and fail to engage with the ATO, your debt may be disclosed to credit reporting bureaus.
