What Is a Director Penalty Notice — and What Does It Mean If You're Selling Your Business?

Most business owners don't hear about Director Penalty Notices until it's too late.

You're running a business. You've kept staff employed through tough periods. Occasionally, when cash was tight, you delayed a BAS payment or let superannuation fall behind for a quarter. You told yourself you'd catch up. The business has been getting back on track.

Then a letter arrives from the ATO.

A Director Penalty Notice — commonly called a DPN — is one of the most serious enforcement tools the ATO has. It makes you personally liable for your company's tax debts. Not the company. You.

If you're thinking about selling your business, a DPN sitting in the background can kill a deal before it gets to contract. Here's what every business owner needs to understand.

What is a Director Penalty Notice?

A Director Penalty Notice is a formal notice issued by the Australian Taxation Office (ATO) that transfers personal liability for certain company tax debts to the company's directors.

The debts covered by a DPN are:

• PAYG withholding tax — the tax you're legally required to withhold from employee wages and remit to the ATO
• Superannuation Guarantee Charge (SGC) — the penalty that arises when you fail to pay compulsory super contributions for employees by the quarterly deadline
• GST — under the newer rules extended from 2020, unpaid GST can also be subject to a DPN

The legislation that enables DPNs is the Taxation Administration Act 1953. The ATO can issue a DPN to any current director, and in some cases to former directors, if obligations arose during their time in the role.

Two types of DPN — and why the difference matters enormously

Not all DPNs are the same. There are two types, and the options available to you depend entirely on which one you've received.

Non-lockdown DPN (the one you can work with)

A non-lockdown DPN is issued when your company has reported the relevant obligations (lodged the BAS or SGC statement) but hasn't paid them. You've told the ATO what you owe — you just haven't paid it yet.

When you receive a non-lockdown DPN, you have 21 days to take one of three actions:

1. Pay the debt in full
2. Place the company into voluntary administration
3. Wind up the company (commence liquidation)

If you do one of those three things within 21 days, the personal liability is lifted. If you don't act within 21 days, the DPN becomes locked down — and your options narrow dramatically.

Lockdown DPN (the serious one)

A lockdown DPN is issued when the company has not reported by the due date — meaning the BAS was never lodged, or the SGC statement was never filed.

This is significantly worse. With a lockdown DPN, the only way to escape personal liability is to pay the debt in full. Voluntary administration and liquidation do not extinguish the liability.

The logic is deliberate: the ATO views a director who failed to even report the obligation as more culpable than one who reported and struggled to pay.

Feature	Non-Lockdown DPN	Lockdown DPN
Triggered when	Reported but unpaid	Unreported (not lodged)
Response window	21 days to act	21 days — but options are limited
Voluntary admin escape?	Yes — can extinguish liability	No — does not extinguish liability
Liquidation escape?	Yes — can extinguish liability	No — does not extinguish liability
Only escape route	Pay, admin, or wind up	Pay in full

How does a DPN affect a business sale?

If you're thinking about selling your business and there's a DPN in the background — or the conditions that would trigger one — it affects the sale in four distinct ways.

1. Disclosure obligations

In any business sale, you have an obligation to disclose material liabilities. A DPN is a material liability. If you receive one and don't disclose it to a buyer, you're potentially exposed to claims of misrepresentation after the deal closes.

In a share sale (where the buyer acquires the company itself rather than just its assets), unpaid PAYG and SGC obligations come with the company. A buyer's solicitor doing proper due diligence will find these liabilities in the company's BAS history, the ATO running balance, and any correspondence from the tax office.

2. Deal structure pressure

Buyers who find ATO debt during due diligence don't typically walk away. They renegotiate. Common approaches include:

• A price reduction equal to the outstanding ATO debt (plus interest and penalties)
• Holdback provisions — money held in escrow after settlement until the ATO liability is confirmed resolved
• Indemnity clauses requiring you to personally cover any additional ATO claims that emerge after settlement

The later a buyer discovers the liability, the more aggressively they'll use it as leverage. If they find it after heads of agreement are signed, you've already mentally committed to the deal — and they know it.

3. Personal liability doesn't disappear at settlement

This is the part that surprises most people.

Selling your business does not extinguish a DPN. The notice attaches to you personally as a director — it doesn't sit with the company or its assets. Even after settlement, even after you resign as a director, the ATO can still pursue you for the outstanding debt.

In practice, this means the proceeds from your business sale may be the only asset you have left once the company is gone — and the ATO can come directly after those proceeds.

4. Timing of your sale may be critical

If you've received a non-lockdown DPN and have 21 days to respond, the sale of your business is almost certainly not going to close within that window. This creates a problem: if you miss the 21-day window without acting, the DPN locks down and your only option is full payment.

This is why DPN discovery during a sale process often triggers an emergency — and why it's far better to deal with it before you go to market than during negotiations.

What can you do if you have an outstanding DPN?

The right path depends on the type of DPN, the amount owed, and where you are in the sale process.

Option 1: Pay it out before the sale

The cleanest solution is to clear the ATO debt before listing or before entering heads of agreement. This removes it from the equation entirely. You approach the sale with clean books, clean disclosure, and no leverage point for a buyer to exploit.

If you don't have the cash to pay it outright, you may be able to negotiate a payment plan with the ATO. The ATO generally prefers a payment arrangement to collecting nothing. However, any arrangement needs to be fully disclosed to a buyer — it's still a liability, just a managed one.

Option 2: Negotiate the sale price to account for the debt

In some cases, especially in asset sales, the ATO debt stays with the company shell and the buyer acquires only the business assets. The seller retains the liability. The sale proceeds reflect the agreed business value, and separately the seller deals with the ATO from those proceeds.

This structure requires careful documentation and good legal advice — but it can allow a sale to proceed cleanly when the debt is known and quantified.

Option 3: Dispute the notice

There are limited grounds to dispute a DPN — primarily that you were not actually a director during the period in question, or that you took reasonable steps to avoid the liability (which has a narrow legal definition). Disputes require specialist tax law advice and must be initiated quickly.

Option 4: Address it through voluntary administration (non-lockdown only)

If the DPN is non-lockdown and the business is genuinely insolvent or near-insolvent, voluntary administration may be the appropriate path. It's not appropriate for a viable business simply trying to manage a tax payment — but if the situation has deteriorated significantly, it may be the right framework.

If you've resigned as a director — you may still be liable

A common misconception is that resigning as a director removes your exposure to a DPN. In many cases, it doesn't.

The ATO can issue a DPN to a former director if:

• The obligation arose while you were a director
• You resigned less than 30 days before the obligation was due but unreported
• In some circumstances, if the company continued to incur liabilities while you were taking steps to exit the directorship

The safest approach is never to assume that resignation has cleared the liability. Get formal advice before proceeding.

What does this look like in practice?

Imagine a family-owned manufacturing business with eight staff. Over two difficult years, the owners fell behind on superannuation — they paid wages first and intended to catch up on super when cash improved. The BAS was always lodged, but the SGC statements for three quarters were never filed.

When they eventually decide to sell and engage a business adviser, the due diligence process reveals $140,000 in unremitted SGC plus penalties and interest. Because the SGC statements were never lodged, any DPN the ATO issues will be a lockdown notice — payable in full, no way out through voluntary administration.

The buyer's adviser finds it in the first week of due diligence. The buyer uses it to demand a $175,000 price reduction (the debt plus a contingency buffer). The seller, who had mentally committed to the deal, accepts.

The outcome could have been different if the obligation had been discovered and disclosed — or better still, resolved — before the sale began.

Practical checklist: what to do before you sell

Before you take a business to market, run through these checks:

1. Get an ATO running balance. Your accountant can access your ATO portal to confirm the current position on PAYG, SGC, and GST. Do this before you talk to a broker or buyer.
2. Check for unreported obligations. If any BAS or SGC statements are unfiled, lodge them immediately. Unreported obligations are the trigger for a lockdown DPN — which is far harder to deal with than a reported-but-unpaid one.
3. Quantify the liability fully. Include principal, general interest charge (GIC), and penalties. The ATO calculates GIC daily, so a debt that looks manageable can grow quickly.
4. Get tax advice before listing. A tax lawyer or experienced business accountant can advise on the best approach — whether that's a payment plan, dispute, or restructure — before the liability becomes a buyer's leverage point.
5. Disclose early and cleanly. If there is an ATO liability, disclose it to your adviser upfront so it can be factored into the asking price and deal structure, rather than used as a renegotiation tool mid-process.

The broader point about clean books

A DPN is an extreme version of a more general issue: tax and payroll obligations that haven't been managed cleanly over time. Buyers look hard at this.

Even without a formal DPN, a history of late BAS lodgements, irregular super payments, or ATO payment plans sends a signal to buyers about how the business has been run. It creates uncertainty about what else may have been deferred or managed loosely.

The businesses that attract the best buyers — and the highest multiples — are the ones with clean, transparent financials and no pending ATO complications. That standard is worth working toward years before you intend to sell.

If you're not sure where your business sits, the most useful thing you can do is understand what a buyer's due diligence would find. That starts with knowing your own numbers — including what the ATO knows about you.
