Lockdown vs Non-Lockdown DPNs: The One Thing That Decides Your Personal Liability

Lockdown vs Non-Lockdown DPNs: The One Thing That Decides Your Personal Liability
Two directors get a Director Penalty Notice for the exact same amount on the exact same day. One of them can still walk away clean. The other is already personally on the hook and there's nothing a liquidator can do about it. The difference between them isn't how much they owe. It's when the company lodged its BAS. That's the single fact that decides everything, and almost no director knows it until it's too late.
If you're not yet clear on what a DPN is or how the 21-day clock works, start with the primer — Director Penalty Notices Explained — then come back here. This article is about one thing only: the lodgement line that decides whether you're exposed.
Non-lockdown: lodged within 3 months
A non-lockdown DPN is what you get when the company lodged its BAS within three months of the due date. The debt might still be unpaid — that's fine for this purpose. What matters is that the ATO was told about it on time.
Because the reporting was done, you still have room to move. You get 21 days from the date of the notice to take one of four actions and remit the penalty:
- Pay the company's outstanding amount in full.
- Appoint an administrator (Voluntary Administration).
- Appoint a Small Business Restructuring (SBR) practitioner.
- Begin winding the company up.
Do one of those inside the window and the personal liability comes off. This is the DPN you can work with. It's tight, but it's survivable — the doors are open, and part of my job is helping you pick the right one before the 21 days run out.
Lockdown: not lodged within 3 months
A lockdown DPN is a different animal. It's what you get when the BAS wasn't lodged within three months of the due date. And here's the hard part: by the time the notice arrives, the personal liability is already locked in.
That means:
- Appointing an administrator won't remit it.
- Appointing an SBR practitioner won't remit it.
- Liquidating the company will not, by itself, remove it.
Three of the four escape routes are gone. The only way to remit a lockdown penalty is to pay the company's debt in full. Closing the company down doesn't extinguish it — the debt follows you personally, and it will follow you into bankruptcy if it gets that far.
Let that sink in, because it's counter-intuitive. Directors assume liquidation is the emergency exit. With a lockdown DPN, it isn't. The exit was locked the day the lodgement passed the three-month mark — long before the notice ever hit the letterbox.
ATO estimates are treated as lockdown
There's a second way to end up locked in, and it catches the directors who go quiet.
If the company doesn't report PAYG, GST or SGC by the due date, the ATO can estimate the amount itself and issue a notice of that estimate. The estimated amount is due the day the estimate is issued, and director penalties apply immediately. Because nothing was ever reported, an estimate is treated the same as a lodgement that was never made — which puts it squarely in lockdown territory.
So burying your head doesn't buy time. It removes options. Silence gets treated as the worst-case version of late.
Lodgement behaviour, not the size of the debt
This is the point I want every director to hold onto: your exposure is decided by lodgement behaviour, not by how big the debt is.
A company that owes a modest amount but never lodged is in a worse position than a company that owes far more but lodged on time. The one that reported keeps all four options. The one that went dark has one — pay in full — and that's usually the option nobody can afford.
In practice, that flips how you should think about a company in trouble. When cash is tight, the instinct is to stop lodging because you can't pay. That's the exact move that turns a manageable problem into a personal one. Lodge on time even when you can't pay. Lodging keeps you on the non-lockdown side of the line, where the four options live. A late lodgement that crosses the three-month mark quietly converts a company debt into a debt that can take your house.
The defences exist — but they're harder than they sound
There are limited statutory defences to a director penalty, and they're worth knowing so you don't pin your hopes on them without understanding what they demand. You won't be liable if, for the entire period the obligation existed, one of these held:
- You couldn't take part in management because of illness or another acceptable reason, or
- You took all reasonable steps to make the company pay, appoint an administrator, appoint an SBR practitioner, or begin winding up, or
- For GST or SGC, the company applied the relevant law in a way that was reasonably arguable and took reasonable care.
The courts have made these genuinely hard to run. Relying on your co-directors or your accountant is not a defence. The defence has to cover the whole period, not just the tail end when things went wrong. Resigning doesn't help. And any defence has to be lodged in writing with the Commissioner. If the ATO rejects it, you have 60 days from a garnishee or recovery action to seek judicial review. These are real doors, but they're narrow, and they're not a substitute for acting inside the 21 days.
The honest read: don't build your plan around a defence. Build it around getting on the right side of the lodgement line, and around using the 21-day window while it's live. That's where the leverage is.
