The Australian Taxation Office has a letter. Every small-business director in the country should know what it is, what it says, and what it forecloses. Most do not, until the letter arrives.
The Director Penalty Notice is the legal instrument that allows the ATO to pursue a company’s unpaid GST, PAYG withholding and superannuation guarantee charge amounts from the personal balance sheet of its directors. It has been on the books for decades. For most of the past ten years it was used sparingly; through 2020 to 2022 the ATO suppressed it almost entirely. Since mid-2023 it has been one of the ATO’s primary collection tools.
In the 2023-24 financial year, per the ATO’s own annual reporting, more than 26,000 DPNs were issued. Insolvency firms including McGrathNicol and Worrells reported DPN-related enquiries up sharply through the 2024 and 2025 calendar years. The Commissioner, Rob Heferen, signalled in a June 2024 address to the Tax Institute that the office would “firm up” its debt-collection stance. That signal has been implemented.
The two variants, stated plainly
There are two DPN variants, and the difference between them is the entire story.
The standard DPN is issued after a company has lodged its activity statements or super contribution forms on time, but not paid the associated debts. The director receives a notice that gives them 21 days to take one of a small number of actions: pay, enter into a payment arrangement acceptable to the ATO, appoint a small-business restructuring practitioner, appoint a voluntary administrator, or liquidate the company. If they do any of those within 21 days, the director’s personal exposure lapses.
The lockdown DPN is issued where the company has failed to lodge activity statements or super forms within three months of the due date. A lockdown DPN does not offer the 21-day escape. It converts the company’s debt into a personal director’s debt with immediate effect, and the only way to reduce it is to pay.
The Tax Institute and the Law Council of Australia have both flagged in 2024-25 that the lockdown variant is poorly understood even by directors who have been in business for decades. The common assumption, one that held under the pre-2023 collection posture, is that if the company is wound up the director is relieved of the associated liability. For the lockdown variant that assumption is wrong.
Who is being hit
The sectoral pattern is consistent with the broader insolvency wave. Construction and hospitality directors are over-represented in the DPN cohort, partly because those sectors are over-represented in the underlying tax-debt pool, and partly because their cashflow profile makes on-time lodgement harder in bad quarters. ASIC’s insolvency statistics showed company collapses exceeding 14,000 in the twelve months to March 2025, a record. A material fraction of those collapses were precipitated by DPN activity.
The ASBFEO, Bruce Billson, publicly called in 2025 for the ATO to engage earlier with small businesses before the DPN is issued, a request that implicitly concedes that for many of the businesses receiving one, the letter is the first substantive ATO communication about a debt that has been accruing for two or three years.
Earlier engagement by the ATO with small business, before the DPN, would turn fewer viable companies into insolvencies and fewer viable directors into personal bankrupts.
The collectable debt number behind it
The macro number that explains the shift is the ATO’s collectable debt, which stood at roughly $52.4 billion at 30 June 2024, up from $44.8 billion a year earlier. Small business represented approximately two-thirds of that total. The ATO’s forbearance through 2020 to 2022 was, in effect, an interest-free loan to the small-business sector of a meaningful multiple of the annual instant-asset-write-off programme. The DPN wave is, partly, the clean-up of that arrangement.
What directors are doing about it
Three patterns are visible in the insolvency-practitioner commentary for 2024-25.
The first is earlier engagement. Directors who receive a standard DPN are more likely than in prior cycles to enter a payment arrangement within the 21-day window rather than let the clock run out. That is partly a function of publicity and partly a function of better advice from the accounting profession, which has itself come up the learning curve.
The second is increased use of the small-business restructuring process, introduced in 2021 for companies with liabilities under $1 million. SBR has proved operationally more viable than voluntary administration for the single-director companies most exposed to the DPN programme. Its uptake has been rising through 2024 and 2025.
The third, less visible, is personal bankruptcy. The Australian Financial Security Authority’s bankruptcy data through 2025 shows a rising share of personal bankruptcies with company-director-related tax liabilities as a stated cause. Many of these are the end-point of a DPN that the director could not answer in time.
The practical note
For a director whose company has any level of overdue GST, PAYG or super, the practical note is short. Lodge on time, even if you cannot pay. Lodgement is what preserves the 21-day escape route on a DPN; non-lodgement is what triggers the lockdown variant. That is the single most important operating discipline in a small-company tax environment in 2026. It is also the one most commonly abandoned in a cashflow crisis, at exactly the moment it matters most.
The Commissioner has made the posture clear. The DPN is not a warning. It is an instrument the ATO now uses routinely. The small-business sector is still adjusting to that fact.
