A director penalty notice (DPN) is the mechanism the ATO uses to make company directors personally liable for certain unpaid company debts. It's the single biggest reason "just let the company go dormant" is worse advice than it sounds.
What a DPN covers
DPNs can apply to three types of unpaid company liabilities: PAYG withholding, GST (net amounts under the estimated GST liability rules), and superannuation guarantee charge. If these remain unpaid and unreported for long enough, the ATO can issue a notice making each person who was a director during the relevant period personally liable for the amount — separate from whatever happens to the company itself.
Lockdown vs non-lockdown DPNs
If the liability was reported (lodged) within the required timeframe but simply not paid, a director generally has options to avoid personal liability — paying the debt, entering payment arrangements, or placing the company into administration or liquidation within 21 days of the notice. If the liability was never reported at all, it becomes a "lockdown" DPN — the only way to avoid personal liability is to pay the debt in full. There's no administration or liquidation escape hatch once it's lockdown.
Why this matters specifically when closing
This is precisely why our eligibility check flags unpaid PAYG withholding and super guarantee before anything else — a company can look simple and debt-free on the surface while carrying exactly the liabilities that turn into personal risk for directors. Voluntary deregistration doesn't extinguish a DPN already on foot, and it doesn't stop the ATO issuing one after the fact if the underlying debt was never properly reported and paid.
If you've already received a DPN
This isn't a self-service situation — get advice from a registered tax agent or lawyer immediately. The 21-day window to act is a hard deadline, not a guideline.
This is general information, not legal or tax advice — DPN rules are detailed and time-sensitive; get advice specific to your notice before doing anything else.
