Construction businesses are carrying record ATO debt. Most don't know how close they are to enforcement.

The ATO isn't waiting for EOFY to pass. For construction businesses carrying debt, the enforcement clock is already running – and the distance between "we're managing it" and a garnishee notice on your bank account is shorter than most directors realise.

Here's the thing that doesn't get said enough: the ATO's escalation to enforcement is driven largely by silence. Not inability to pay. Silence. Businesses that haven't responded to ATO correspondence, that have let lodgements slip, that have been managing the debt informally and hoping for a better month – these are the businesses that move to the front of the enforcement queue. Engaging early, even when the debt is significant and you can't pay it in full, preserves options that disappear once formal action begins.

The gap between the headline data and reality

If you looked only at the headline figures for Australian construction this year, you'd be reasonably optimistic. ABS data for the March 2026 quarter showed sales up and profits up. The sector appears to be moving in the right direction.

Those numbers reflect the top of the market. For small and medium construction businesses – the builders, subbies, and sole traders who make up the overwhelming majority of the sector – the picture looks nothing like that.

New tax debt default disclosures for construction businesses spiked 49% in the first quarter of 2026. Business exits were 10% higher year on year. Construction accounts for $4.3 billion in disengaged collectable debt – more than double the next closest industry. Since 2021–22, insolvency appointments in the sector have almost tripled.

The top line is holding. The bottom half is under serious pressure.

Why construction businesses end up here

It's worth being honest about how this happens, because it's rarely the result of poor management or bad intentions.

Fixed-price contracts signed before material costs spiked left many businesses locked into jobs they couldn't complete profitably. Thin margins left no buffer when subcontractor costs rose or payment timelines slipped. GST collected on progress payments got used to fund operations before the BAS fell due. PAYG withholding got deferred. Super got stretched.

The business kept moving. The ATO account kept falling behind. And because the work was still coming in, it never felt like the right moment to stop and deal with it.

That's the pattern. It's common, it's understandable, and it doesn't make the consequences any less serious.

What happens when the ATO moves

The ATO has publicly committed to deploying its full enforcement powers – director penalty notices, garnishee action, and where necessary, wind-up proceedings. Between July 2024 and March 2025 alone, it issued more than 59,000 director penalty notices and over 10,000 garnishee notices.

A garnishee notice served on your bank requires the bank to redirect funds directly to the ATO – no court order, often with very little warning. For a business running on normal working capital, that can make it impossible to meet wages or supplier payments within days.

Once a lockdown director penalty notice has been issued, personal liability for unpaid PAYG, GST, and super is fixed. No subsequent corporate action changes that. The question stops being "can we resolve this?" and becomes "how much of this follows me personally?"

From 1 July 2025, GIC and SIC are no longer tax-deductible – meaning every additional month a debt sits unresolved costs more than it did the year before.

What early engagement actually looks like

Payment arrangements can be negotiated. Debt quantum can be disputed. Formal restructuring tools exist that allow a business to trade through a difficult period without liquidation. These are real pathways – but they require early engagement to work.

The new financial year is when the ATO refreshes its enforcement focus. Businesses that haven't engaged through 2025–26 move to the front of the queue. The next three weeks represent a genuine window.

In 17 years of insolvency and restructuring work, the one thing that separates the businesses that get through this from the ones that don't is almost always the same: they made the call before the ATO did.

If your construction business is carrying ATO debt – whether it's an arrangement under pressure, an overdue BAS, or a liability you've been managing month to month – now is the time to get a clear picture of where you stand.
