In Australia, GST debt is treated as an unsecured liability in liquidation, ranking behind secured creditors and employee entitlements. However, the ATO can issue a Director Penalty Notice (DPN) making directors personally liable for unpaid GST where Business Activity Statements are not lodged within three months of the due date, and that personal liability can survive the company’s liquidation. We have seen this scenario play out for SME owners and founder-led businesses who assumed winding up a company would draw a line under their tax obligations. It does not.
Key facts to understand before taking any action:
- GST debt in an Australian liquidation is unsecured and ranks behind secured creditors and priority employee claims
- The ATO can issue a DPN within 21 days of a statutory demand, converting a company debt into a personal director liability
- Where a Business Activity Statement (BAS) is not lodged within three months of the due date, the DPN becomes “lockdown” and cannot be remitted by placing the company into administration or liquidation
- The ATO has broad recovery powers including garnishee orders, credit reporting disclosure, and winding-up applications
- Early engagement with the ATO, before a statutory demand is issued, preserves the most options
How the ATO Classifies GST Debt in an Insolvency
GST debt in Australia sits as an unsecured creditor claim in a liquidation. Unlike some jurisdictions, the ATO does not hold preferential creditor status for GST in the way that, for example, the UK’s HMRC does for VAT.[1] In practice, this means GST arrears are distributed from whatever is left after secured creditors, liquidator fees, and priority employee entitlements are satisfied. For many insolvent SMEs, that pool is empty.
The classification matters because it shapes what the ATO will recover through a liquidation, and what it will instead pursue through other mechanisms. The ATO is a sophisticated creditor. It understands exactly where GST sits in the waterfall, and it has built statutory tools specifically designed to reach beyond the company’s assets when those assets fall short.[2]
The A New Tax System (Goods and Services Tax) Act 1999 governs how GST obligations are handled when an external administrator is appointed. Once an insolvency practitioner steps in, the company becomes an “incapacitated entity” and the practitioner assumes reporting obligations in their own right.[1] The GST period is effectively split at the date of appointment, creating two separate tax periods and two sets of obligations.
Director Penalty Notices: When GST Debt Becomes Personal
This is where the risk becomes acute for directors of SMEs and privately owned groups.
The ATO’s Director Penalty Notice regime converts a company’s unpaid GST into a personal liability of each director. The mechanism is set out in Division 269 of Schedule 1 to the Taxation Administration Act 1953. A DPN is not a warning letter. It is a formal legal notice that starts a 21-day clock, after which the ATO can commence recovery proceedings against the director personally.[2]
There are two types of DPN, and the distinction is critical.
Non-lockdown DPNs apply where the BAS has been lodged, even if the GST remains unpaid. A director served with a non-lockdown DPN can remit the penalty by placing the company into voluntary administration or liquidation within the 21-day window.
Lockdown DPNs apply where the BAS was not lodged within three months of the due date. Once a lockdown DPN is issued, placing the company into administration or liquidation does not extinguish the director’s personal liability. The debt follows the director. It can survive the company’s winding up and, in some circumstances, can survive personal bankruptcy as well.[2]
For directors of founder-led businesses or family-owned and operated businesses who have been using unremitted GST as working capital, this is the scenario that causes the most damage. The company may be wound up, but the director’s personal financial position remains exposed.
We have written in detail about how DPNs are coming faster and more often than ever, and the ATO’s enforcement posture has hardened further since then.
What the ATO Can Do Before Liquidation
The ATO does not wait for a formal insolvency appointment to act. Its debt recovery toolkit is broad, and it deploys these tools progressively as arrears age.[2]
Garnishee notices allow the ATO to redirect funds from a company’s bank accounts or debtors directly to the ATO, without a court order. This can stop trading operations overnight.
Credit reporting disclosure is a more recent escalation tool. The ATO can notify credit reporting bureaus of a tax debt above a threshold, damaging the company’s ability to obtain finance or supplier credit. A notice of intent to disclose is a serious warning sign that the ATO has moved beyond reminders.
Statutory demands under the Corporations Act 2001 require the company to pay, secure, or compound the debt within 21 days. Failure to comply creates a presumption of insolvency, which the ATO can then use to support a winding-up application in the Federal Court or Supreme Court.[2]
The ATO does not require director consent to commence winding-up proceedings. It can apply to the court in the same way as any other creditor, and it does so with increasing frequency.
Understanding how the ATO selects who to audit and how its debt recovery methods escalate gives directors a clearer picture of where they sit on the ATO’s priority list before formal action begins.
GST Debt and Insolvency: Options That Remain Open
The options available to a director facing GST debt narrow sharply as the debt ages and as lodgement deadlines pass. The earlier you engage, the more levers remain available.
Payment arrangements are the most common outcome for SMEs that engage with the ATO before a statutory demand is issued. The ATO has a formal process for negotiating instalment arrangements on tax debts, and it will generally consider these where the company demonstrates a genuine capacity to pay and a commitment to future compliance. General interest charge (GIC) continues to accrue on outstanding amounts, so a payment arrangement does not stop the clock on interest costs.
Voluntary administration preserves the option to remit a non-lockdown DPN and may allow a Deed of Company Arrangement (DOCA) to be negotiated with creditors, including the ATO. The ATO participates in voluntary administrations as a creditor and will vote on any proposed DOCA. The ATO retains full discretion to reject any offer, and will give genuine consideration to proposals where the return exceeds what would be recovered in liquidation.
Small business restructuring under Part 5.3B of the Corporations Act 2001 is available to companies with liabilities under $1 million. This process allows directors to retain control while a restructuring plan is developed and voted on by creditors. GST arrears can be addressed through a restructuring plan, and the ATO has engaged with this process since its introduction in January 2021.
Objections and disputes remain available where the GST assessment or DPN itself is incorrect. If the ATO has assessed GST on a transaction that was not a taxable supply, or has issued a DPN based on incorrect lodgement records, a formal objection can be lodged. The six stages of a tax dispute and the process for lodging an ATO objection are areas where specialist advice makes a material difference to the outcome.
What Happens to GST Debt at the End of Liquidation
When a company is wound up with outstanding GST arrears, the debt does not automatically disappear. The liquidator must lodge all outstanding BAS returns and account for GST on any asset realisations during the winding-up process.[1]
GST collected on post-appointment supplies is a priority obligation of the liquidator in their capacity as representative of the incapacitated entity. Pre-appointment GST arrears rank as an unsecured creditor claim and are paid from whatever funds remain after higher-priority claims are satisfied.
Where the company’s assets are insufficient to cover the GST debt, the ATO’s recourse is the DPN regime. Directors who received a lockdown DPN remain personally liable for the unpaid amount regardless of the outcome of the liquidation. The ATO can and does pursue directors personally after a company is wound up.[2]
For sole traders, the position is more direct: there is no corporate veil. GST debt is a personal liability from the outset, and insolvency proceedings address the individual’s estate directly.
Frequently Asked Questions
Can I get my GST bad debts written off?
GST registered businesses can claim a decreasing adjustment for bad debts under section 21-5 of the A New Tax System (Goods and Services Tax) Act 1999, where a debt has been written off as bad or remains unpaid for 12 months. This reduces your net GST liability, but it does not extinguish a GST debt already assessed and owing to the ATO. Writing off a bad debt in your accounts and resolving a GST liability with the ATO are two separate processes.
What are the consequences of bad debts under GST?
When a creditor writes off a bad debt, they can claim a decreasing adjustment to recover the GST component previously remitted. The debtor, if GST-registered, must make an increasing adjustment to repay any input tax credit claimed on the original purchase. In an insolvency context, the liquidator must account for these adjustments in the BAS lodgements filed during the winding-up period, which can affect the net GST position of the estate.[1]
What debt cannot be forgiven in Australia?
In personal insolvency, most unsecured debts, including GST arrears owed personally by a sole trader or director under a lockdown DPN, are provable debts in bankruptcy. However, certain debts survive bankruptcy and cannot be discharged: these include court-ordered fines, child support obligations, and debts incurred by fraud. A lockdown DPN liability sits in a complex position and specialist advice is essential before assuming bankruptcy will extinguish it.
What happens if you never pay your tax debt in Australia?
The ATO has broad powers to recover unpaid tax debts and will escalate through a structured sequence: reminders, payment plan offers, garnishee notices, credit reporting disclosure, statutory demands, and winding-up or bankruptcy applications. General interest charge accrues daily on outstanding amounts, compounding the total owed. For directors, the DPN regime means personal liability can be imposed before the company reaches formal insolvency. Sustained non-engagement is the highest-risk position a director can take.[2]
Can the ATO force a company into liquidation over GST debt?
The ATO can apply to the Federal Court or a Supreme Court to wind up a company that has failed to comply with a statutory demand within 21 days. The company’s failure to pay, secure, or compound the debt creates a presumption of insolvency under the Corporations Act 2001, and the ATO uses this mechanism with increasing frequency. Directors who receive a statutory demand should seek specialist advice within days of receipt.[2]
