Director Penalty Notices (Lockdown vs 21-Day Notice)

The difference between a standard DPN and a lockdown DPN decides whether a director can still act — and how much time they have.

What a DPN is

Under Australian tax legislation, the Australian Taxation Office (ATO) has statutory powers to pierce the corporate veil and recover certain corporate tax debts directly from company directors. The primary instrument used for this purpose is the Director Penalty Notice (DPN).

While an Australian proprietary limited company is a separate legal entity that normally shields directors from corporate debt, Division 269 of Schedule 1 to the Taxation Administration Act 1953 establishes an ongoing personal duty for directors to ensure the company pays its PAYG withholding, Goods and Services Tax (GST), and Superannuation Guarantee Charge (SGC) on time.

Director penalty: Under Division 269 of Schedule 1 to the Taxation Administration Act 1953, company directors have a personal statutory obligation to ensure the company pays its PAYG withholding, GST, and Superannuation Guarantee Charge (SGC), or promptly enters formal insolvency. If the company fails to do so, a penalty equal to the unpaid company liability is automatically imposed on each director personally.

When a company fails to pay or report these liabilities, the ATO issues a DPN setting out the unpaid amounts. Whether the director can escape personal liability depends entirely on which type of DPN is issued: a standard 21-day notice or a lockdown DPN.

The 21-day notice

A 21-day notice, commonly called a standard or non-lockdown DPN, is issued when a company has lodged its Business Activity Statements (BAS) and SGC statements within the required statutory reporting timeframes, but has been unable to pay the underlying liabilities.

Because the company complied with its statutory disclosure duties by reporting the debt on time, Commonwealth law grants directors a strict 21-day grace period to avoid personal liability. To remit (extinguish) the penalty under a 21-day notice, the director must ensure the company takes one of four statutory actions within 21 days:

  1. 1.Pay the full outstanding tax debt to the ATO.
  2. 2.Appoint a Small Business Restructuring (SBR) practitioner under Part 5.3B of the Corporations Act 2001.
  3. 3.Appoint a voluntary administrator under Part 5.3A of the Corporations Act 2001.
  4. 4.Place the company into creditors’ voluntary liquidation.

Crucially, entering an informal ATO payment plan or simply negotiating with an ATO case officer does not remit a 21-day DPN. The statutory appointment or full payment must be legally executed before the 21 days expire.

How long have you actually got?

Enter the date printed on the notice, not the day it arrived. A notice is taken to have been given when the ATO posts it, and it goes to the address ASIC holds for you — which is often out of date.

Which kind of notice is it?

This is a calendar-day estimate based on the date you entered, provided as general information. It is not advice about your notice, and it does not account for anything specific to your company. Confirm the position with a registered liquidator or your adviser. Nothing entered here is sent anywhere or stored.

The lockdown DPN

A lockdown DPN is issued when a company has failed to both pay and report its liabilities within the statutory deadlines. Specifically, this occurs when BAS or instalment activity statements remain unlodged for more than three months after their due date, or SGC statements remain unlodged past their statutory reporting date.

Under lockdown conditions, the personal penalty is deemed to have attached to the director automatically on the day the reporting deadline expired. The physical notice issued by the ATO serves merely as a formal demand for payment, not an opportunity to restructure.

Once a lockdown penalty has attached, appointing an administrator, liquidator, or restructuring practitioner will not remit the director’s personal liability. The penalty remains permanently attached to the individual until paid in full or discharged via statutory defence.

How the two differ

Understanding which type of notice applies to your company dictates the legal remedies and restructuring strategies available. The statutory comparison below highlights the operational differences:

Feature21-day DPN (standard)Lockdown DPN
When it is issuedLodgements reported within 3 months of statutory due date, but liabilities remain unpaid.Lodgements unreported more than 3 months past due date (or 28 days for SGC).
How liability arisesConditional penalty created automatically; enforcement held in abeyance during notice period.Permanent personal liability locks onto directors immediately once reporting window lapses.
Whether it can be remittedYes. Remitted in full by restructuring, administration, liquidation, or payment within 21 days.No. Cannot be remitted by appointing a restructuring practitioner or liquidator.
The director’s optionsAppoint an SBR practitioner, appoint an administrator, liquidate, or pay company debt in full.Pay the penalty in full personally or establish narrow statutory defences under s 269-35.
The deadlineStrictly 21 calendar days from the date printed on the notice (not the date received).Immediate upon issue. No grace period exists to avoid personal liability.

What happens if you do nothing

Allowing a 21-day DPN to lapse without taking statutory action produces irreversible legal consequences. On day 22, the conditional penalty becomes an absolute personal debt due and payable by each director to the Commonwealth.

At this stage, the ATO can commence immediate personal enforcement without further warning. Standard recovery measures include:

  1. 1.Issuing Section 260-5 garnishee notices against your personal bank accounts or wages.
  2. 2.Offsetting future personal tax refunds and credits against the corporate penalty balance.
  3. 3.Commencing civil court proceedings to obtain judgment debts over personal real estate.
  4. 4.Issuing formal bankruptcy notices against the director individually.

Resigning as a director after the debt accrued does not extinguish liability. Furthermore, newly appointed directors become personally liable for historical unlodged debts after just 30 days in office.

Where restructuring changes the outcome

For directors holding an active 21-day notice, the Small Business Restructuring (SBR) process under Part 5.3B provides the most viable commercial resolution. Appointing an SBR practitioner on or before day 21 immediately remits the director penalty in full.

Unlike liquidation or voluntary administration, SBR allows the directors to remain fully in control of the business and its banking facilities throughout the restructuring period. The practitioner certifies the restructuring plan, which commonly compromises historical ATO debts to a fraction of their face value.

The 21-day clock begins on the date the ATO deposits the notice in the post to your registered ASIC residential address. Because postal transit counts toward your 21 days, immediate engagement is essential to safeguard personal assets while protecting commercial enterprise value.
