Most tradies who set up a company did it for one reason above all others: to put a wall between the business and themselves. If the business hits trouble, the theory goes, it's the company on the hook, not the family home. For most debts that's true. For three specific tax debts it isn't, and the mechanism the ATO uses to knock that wall down is called a Director Penalty Notice.
This used to be a rare piece of paper. It isn't anymore. In the 2024-25 financial year the ATO issued more than 84,000 Director Penalty Notices to directors of roughly 64,000 companies — a 136 per cent increase on the year before. The Tax Ombudsman has flagged a review of how the ATO administers them, due to start in September 2026, precisely because the volume has jumped so sharply. If you run your trade business through a company and you're carrying any tax debt, this is no longer a remote risk. It's a live one, and the difference between it costing you nothing and costing you personally often comes down to something you do on the day the BAS is due, not the day the notice arrives.
What a DPN actually does
A Director Penalty Notice makes you, personally, liable for three of your company's unpaid tax obligations: PAYG withholding (the tax you take out of your employees' wages), net GST, and the super guarantee charge (unpaid super, plus interest and an admin fee, once it's overdue). These are the amounts the law treats as money you were holding on someone else's behalf — your workers' tax, your workers' super, and the GST you collected for the ATO. Fail to pass them on, and the company's debt can become your debt.
Note what's not on that list: company income tax, ordinary trade creditors, the ute finance. A DPN reaches the three "held on trust" amounts specifically. But for a trade business with a couple of employees, PAYG withholding and super are a big slice of what you owe the ATO in a bad quarter — and now they can follow you home.
The 21-day clock, and the trap inside it
When the ATO issues a DPN, you have 21 days to act. The Commissioner can't start court action to recover the penalty from you personally until those 21 days are up. That sounds like a reasonable window. Here's the catch that ruins people: the 21 days runs from the date the notice is issued and posted, not the date you read it. And it's posted to the address the ATO has on record for you — usually the address on the ASIC register.
If you moved and never updated ASIC, the notice can be sitting in a letterbox at your old place, the clock can be running, and you can find out only when the window has already closed. The ATO has no obligation to make sure you actually received it.
Gold nugget. Spend ten minutes today confirming your address on the ASIC company register is current, and set a rule that any letter that even looks like it's from the ATO gets opened the day it lands, not left on the bench. The single most expensive way to deal with a Director Penalty Notice is to not know you got one until day 22. Every option below depends on acting inside 21 days, and the clock doesn't wait for you to notice.
Lockdown vs non-lockdown: the part that's actually in your control
This is the distinction that matters most, and almost no trade business owner knows it exists.
There are two kinds of DPN, and which one you get is decided long before the notice is written — it's decided by whether you lodged on time.
A non-lockdown DPN is issued when the company reported the debt to the ATO on time (broadly, PAYG withholding and GST reported within three months of the BAS due date, and super guarantee charge statements lodged by their due date) but simply hasn't paid it. With a non-lockdown notice, you have real choices inside the 21 days. You can pay the debt, appoint a voluntary administrator, appoint a small business restructuring practitioner, or appoint a liquidator — and doing any of those remits the penalty, meaning it comes off you personally. The company might still be in trouble, but you're not carrying its tax debt on your own name.
A lockdown DPN is issued when the company didn't lodge on time — it fell more than three months behind on the BAS, or never lodged the super statements. Here the penalty "locks down" onto you, and the only way to remove it is to pay the debt in full. Putting the company into administration or liquidation does not wipe it. You are personally on the hook, full stop.
Read that difference again, because it flips the usual instinct on its head. When cash is tight, the temptation is to not lodge — to go quiet and hope. Not lodging is exactly what converts a manageable, remittable, non-lockdown situation into a lockdown one that follows you personally no matter what happens to the company. Lodging on time, even when you can't pay, is what preserves every option you've got. It's the same lesson as not sitting on a BAS you can't pay, except here the price of silence isn't just interest — it's your own liability.
What to do if one lands on your desk
Don't panic, and don't ignore it — those are the two failure modes. Ring your accountant or an insolvency adviser the same day, because 21 days disappears fast and a couple of the options (appointing an administrator or a restructuring practitioner) take days to set up properly. Work out first whether it's a lockdown or non-lockdown notice, because that decides whether you have four options or one. If it's non-lockdown and the debt is payable, paying it is the cleanest exit. If it isn't, the restructuring and administration paths exist specifically so that directors of viable-but-struggling companies aren't personally ruined by a bad run — but they only work if you move inside the window.
The real fix is upstream, as always
A DPN is a late-stage symptom. The disease is unremitted PAYG and super sitting in a trading account, looking like money you can use, until it isn't. The fix is the same unglamorous one that fixes most trade-business cash problems: the moment wages are paid, move the PAYG withholding and the super into a separate account you don't touch, and lodge every BAS and super statement on time without fail — because on-time lodgement is the thing that keeps any future DPN in the survivable, non-lockdown category. A 13-week cash flow forecast puts super and PAYG on the calendar as line items weeks out, so the money's there when the obligation lands. And if unpaid super is the specific worry, the payday super first-month checklist covers what to verify now that super rides with every pay run.
If you've been carrying tax debt for a while and you're not sure whether you're exposed personally, that's exactly the kind of thing the Trade Business Health Check surfaces — a fixed-price review of your numbers, your obligations and your cash cycle, with a written plan of what to fix first. Or start with the free Business Health Scorecard to see where you stand before you talk to anyone. Either way, this is not a letter you want to be reading for the first time on day 22.
