A non-lockdown DPN applies where the company lodged its PAYG, GST or SGC obligations on time but failed to pay. This preserves restructuring or remission options. A lockdown DPN arises where lodgements were late or not made, meaning directors may remain personally liable even if the company later enters insolvency proceedings.

Introduction
If a company falls behind on PAYG, GST or superannuation obligations, directors may eventually receive a Director Penalty Notice (DPN) from the Australian Taxation Office (ATO). One of the first things to check then, is whether it is a lockdown or non-lockdown DPN.
That distinction can significantly affect what options may still be available. In some situations, directors may still have time to consider restructuring or insolvency options. In others, the liability may already be personally locked in.
This guide explains the difference between lockdown and non-lockdown DPNs, why reporting deadlines matter, how the 21-day rule operates, and what directors should understand if they receive a DPN from the ATO.
What Is a Director Penalty Notice?
A Director Penalty Notice (DPN) is a formal notice issued by the ATO before it begins recovery action against a director personally for certain unpaid company tax debts.
A DPN may relate to unpaid:
- PAYG withholding,
- Goods and Services Tax (GST), and
- Superannuation Guarantee Charge (SGC) liabilities.
Note that the director penalty itself can arise before the DPN is issued. The DPN is the formal notice the ATO must provide before it can begin recovery proceedings against the director personally. Where the debt remains unpaid, the ATO may commence legal proceedings against directors personally.
This means company directors may already be personally exposed before the notice physically arrives.

Lockdown vs Non-Lockdown DPN: Quick Comparison
| Feature | Non-lockdown DPN | Lockdown DPN |
| What usually causes it? | Company lodged required BAS/GST/PAYG or SGC statements on time, but did not pay | Company failed to lodge required statements within the required timeframe |
| Main issue | Debt is unpaid | Debt is unpaid and was not reported on time |
| 21-day period | Yes | Yes |
| Can appointing a voluntary administrator, SBR practitioner or liquidator help? | Potentially, if done within the 21-day period and requirements are met | Generally no, for the locked-down component |
| Is payment still an option? | Yes | Yes |
| Is a defence possible? | Potentially, but only in limited circumstances | Potentially, but only in limited circumstances |
| Risk level | Serious | Usually more serious |
The most important distinction is that a non-lockdown DPN may preserve restructuring and remission options that can be lost once the liability becomes locked down.
What Is a Non-Lockdown DPN?
A non-lockdown DPN generally applies where the company reported the relevant PAYG, GST or SGC liabilities to the ATO within the required timeframe but failed to pay the underlying tax debt.
This distinction is important because timely lodgement may preserve options that can later help directors manage or remit personal liability.
Depending on the circumstances, a director receiving a non-lockdown DPN may still have time to consider options such as:
- Paying the debt,
- Appointing a voluntary administrator,
- Entering Small Business Restructuring (SBR), or
- Beginning liquidation.
What Is a Lockdown DPN?
A lockdown DPN generally applies where the company failed to lodge required PAYG, GST or SGC reporting within the required timeframe.
This usually means the company either:
- Did not lodge the required statements at all, or
- Lodged them too late.
Once a liability becomes locked down, appointing a voluntary administrator, Small Business Restructuring practitioner or liquidator may no longer remit the director penalty for that locked-down amount.
When a director receives a Lockdown DPN, their options are limited, and the only way to avoid personal liability is to pay the debt in full, either by the company if it is still solvent, or by the director personally. Even if the company later enters external administration, the director remains liable for locked-down amounts.
This means the director may not be able to escape personal liability even if the company later enters voluntary administration or liquidation.
When Does a DPN Become Lockdown?
The reporting timeline is one of the most important parts of the DPN regime because it often determines whether directors still have restructuring options available.
- For PAYG withholding and GST liabilities, the key issue is generally whether the required statements were lodged within three months of the due date.
- For Super Guarantee Charge (SGC), the rules are stricter.
| Liability type | Reporting timeframe | Reporting timeframe |
| PAYG withholding | Generally, report/lodge within 3 months of the due date | Late reporting can lock down the penalty |
| GST | Generally, report/lodge within 3 months of the due date | Late reporting can lock down the penalty |
| SGC | Lodge the SGC statement by the SGC statement due date (check table below) | SGC is stricter and can lock down faster |
For SGC, the current quarterly due dates are:
| Quarter | SG payment due date | SGC statement due date |
| 1 July – 30 September | 28 October | 28 November |
| 1 October – 31 December | 28 January | 28 February |
| 1 January – 31 March | 28 April | 28 May |
| 1 April – 30 June | 28 July | 28 August |
From 1 July 2026, Payday Super reforms are expected to change how employers calculate, pay and report super guarantee obligations. Directors should check current ATO guidance before relying on older quarterly assumptions.
What is The 21-Day Rule?
Once a DPN is issued, directors generally have 21 days before the ATO can begin recovery proceedings against them personally.
Importantly, the 21-day period usually starts from when the notice is sent to the director’s address registered with ASIC — not from when the director actually opens or reads the letter.
Directors should understand that:
- A single DPN may include multiple liabilities,
- Some amounts may be lockdown while others are non-lockdown, and
- Different parts of the notice may have different consequences.
What Directors Should Do If They Receive a DPN
If you receive a Director Penalty Notice, acting quickly is critical — especially if there is uncertainty about whether the notice contains lockdown or non-lockdown amounts.
Directors should:
- Read the notice carefully,
- Identify the 21-day deadline,
- Review the company’s financial position and BAS, GST and SGC lodgement history,
- Check whether liabilities may be lockdown or non-lockdown,
- Avoid assuming the DPN is automatically lockdown or automatically remittable,
- Assess whether restructuring or remission options may still exist, and
- Obtain professional advice before taking action.
Importantly, some DPNs may contain both lockdown and non-lockdown components, meaning different parts of the notice may have different consequences.
Common Mistakes Directors Make After Receiving a DPN
Ignoring the Notice
One of the most common mistakes is assuming the issue can wait or will resolve itself later.
A DPN is time sensitive. The 21-day period continues running whether or not the director responds immediately, and delays can significantly reduce available options.
Ignoring a lockdown Director Penalty Notice (DPN) accelerates enforcement actions by the ATO, which can include garnishee notices to seize funds from personal bank accounts.
Assuming unpaid PAYG, GST or SGC liabilities Are Only a Company Debt
A DPN is specifically designed to make directors personally liable for certain unpaid company tax debts. This means personal exposure can arise even where the company itself is struggling financially.
Thinking Resigning as a Director Solves the Problem
Former directors may still remain liable for debts connected to periods when they were directors. Resignation does not automatically erase existing DPN exposure.

Assuming New Directors Are Automatically Protected
New directors can still become personally liable if existing PAYG, GST or super obligations remain unresolved after they join the company. Before accepting a directorship, it’s important to understand the company’s tax position and any outstanding ATO liabilities.
Lodging Late Because the Company Cannot Pay
Some directors stop lodging BAS, GST or SGC obligations once the company experiences severe cash flow problems.
This can be a major mistake because late lodgement may cause liabilities to become locked down, potentially removing restructuring or remission options that may otherwise have remained available.
Even where payment is impossible, timely lodgement may still preserve important options.
Waiting Too Long to Get Advice
DPN risk can escalate quickly, particularly where lockdown liabilities are involved.
Early advice can help directors:
- Understand whether liabilities are lockdown or non-lockdown,
- Assess restructuring options,
- Identify possible defences, and
- Reduce unnecessary personal exposure.
If a director fails to act on a lockdown DPN, the ATO can obtain a judgment against the director personally, enabling enforcement against their assets. Seek specialist advice at the earliest.
Next Steps
A lockdown and non-lockdown DPN may look similar when they arrive, but they can leave directors with very different options.
Timely lodgement of PAYG, GST and SGC obligations may preserve restructuring pathways that can otherwise be lost once liabilities become locked down. Even where a company cannot pay its tax liabilities, timely lodgement may preserve options that late reporting can remove.
For directors facing ATO debt pressure, understanding whether a DPN is lockdown or non-lockdown is often one of the most important early steps to assess the risk and consider available restructuring options and remission pathways to remove personal liability.

FAQs
What is the difference between a lockdown and non-lockdown DPN?
A non-lockdown DPN generally applies where the company lodged its PAYG, GST or SGC reporting obligations on time but failed to pay the debt.
A lockdown DPN generally applies where the company failed to lodge the required reporting within the required timeframe.
This distinction is important because non-lockdown DPNs may preserve restructuring or remission options that can be lost once liabilities become locked down.
How long do I have to respond to a DPN?
Directors generally have 21 days from when the DPN is given before the ATO can begin recovery proceedings.
Importantly, the timeframe usually starts from when the notice is posted or issued — not from when the director actually opens or reads the letter.

Can voluntary administration stop a DPN?
Yes, but it depends on whether the DPN is lockdown or non-lockdown.
Voluntary administration may help remit certain non-lockdown DPN liabilities if action is taken within the relevant timeframe.
However, it generally will not remit locked-down amounts.
Can Small Business Restructuring help with a DPN?
Potentially, yes.
Small Business Restructuring (SBR) may help with certain non-lockdown DPN liabilities if implemented within the required timeframe.
However, SBR generally will not remove locked-down liabilities.
Can liquidation stop a DPN?
Liquidation may help remit certain non-lockdown DPN liabilities if action is taken within the relevant timeframe.
However, liquidation generally does not remove liability for locked-down amounts.
Does a payment plan remove a DPN?
Not necessarily.
An ATO payment plan may affect recovery action or repayment arrangements, but directors should not assume it automatically remits the director penalty itself.

Can former directors receive a DPN?
Yes.
Former directors may still remain personally liable for certain company liabilities connected to periods when they were directors.
Resigning does not automatically remove DPN exposure.

Can a DPN include both lockdown and non-lockdown amounts?
Yes.
A single DPN may contain multiple liabilities or reporting periods, and different parts of the notice may have different consequences.
Some liabilities may be lockdown while others remain non-lockdown.
Can multiple directors receive a DPN for the same debt?
Yes.
If a company has multiple directors, the ATO can issue DPNs to more than one director for the same unpaid tax debt. Other directors should not assume someone else is handling the issue simply because responsibility is shared.
Can late lodgements create a lockdown DPN?
Yes.
Late lodgement of PAYG, GST or SGC obligations may cause the liability to become locked down, potentially removing restructuring or remission options that may otherwise have existed.
This is one of the main reasons timely reporting remains important even during severe financial distress.
Is GST included in a Director Penalty Notice?
Yes.
DPNs may relate to unpaid GST liabilities, along with PAYG withholding and Super Guarantee Charge (SGC) liabilities.
Can you defend a DPN?
Yes, but DPN defences are limited and often evidence-heavy.
In some situations, statutory defences may apply, including certain cases involving:
- Serious illness,
- Not participating in management for good reason,
- Taking reasonable steps to ensure compliance, or
- Certain GST or SGC-related circumstances.
