Construction company ATO debt: funding for builders and subcontractors

Why is construction so exposed to tax debt?

Building is one of the few industries where a business can be busy, profitable on paper and still short of cash every week. The reasons are structural:

• Progress claims. Work is billed in stages, and payment can take weeks after each claim — longer if a head contractor or developer is struggling.
• Retentions. A slice of each payment is held back for months, sometimes until well after practical completion.
• Fixed outgoings. Wages, PAYG withholding and now super under Payday Super fall due on the same timetable whether or not a claim has been paid.
• Materials. Suppliers want paying on account terms that rarely match the claim cycle.
• GST timing. Depending on how the business accounts for GST, it may be payable on invoices issued before the cash arrives.

It’s no surprise that ASIC’s October 2026 insolvency update showed construction accounted for 24.5% of the 14,153 companies that entered external administration for the first time in 2025–26 — the largest share of any industry. Many of those businesses had tax debt at the centre of the story.

Which ATO debts hurt builders most?

Debt	Why it matters for a builder
PAYG withholding	Large wage bills mean large withholding — and director penalty exposure
Super guarantee charge	Payday Super means super is due within 7 business days of each payday; misses attract an uplift starting at 60%
GST	Can be payable before progress payments are received
Income tax	A big project year can produce a big assessment

PAYG withholding, super and GST are all covered by the director penalty regime. If any of them is reported more than three months late — or the ATO estimates it — only full payment remits the director’s personal liability. For a builder with a big crew, that exposure grows fast. See PAYG withholding debt and super guarantee charge debt.

How can funding help a builder?

The aim is usually to clear the taxes that create personal exposure, then give the business enough room to collect what it’s owed:

• Property-secured funding ($20,000 to $5,000,000) against a home, yard or investment property. Funding is possible in as little as 24 hours for urgent deadlines.
• Unsecured funding (typically $5,000 to $500,000) for builders and subbies with strong deposits.
• A split approach — fund PAYG withholding, GST and super; put income tax on an ATO plan.

Where arranged, the ATO is paid directly at settlement. Lenders will want to see your order book, aged debtors and how retentions will flow back, because those are your exit. An illustrative example: a carpentry subcontractor owed the ATO for three quarters of withholding and super after a head contractor collapsed owing it money. A second mortgage over the director’s home cleared the director-penalty debts within the DPN window; the loan is being repaid from new contracts with prompter-paying builders.

What should a builder do this week?

1. Lodge every BAS on time, even if you can’t pay. It keeps withholding and GST out of the lockdown.
2. Pay super with every pay run — set it up so it goes out automatically.
3. List aged debtors and retentions with expected release dates.
4. Pull your ATO statement of account.
5. Talk to your accountant about which ATO amounts carry director exposure.
6. Call us if a DPN or garnishee notice has arrived. Deadlines decide what’s possible.

Is restructuring the better option for builders?

Construction is one of the industries where small business restructuring is often discussed. It can work for some, but read the fine print: employee entitlements including super must be paid and lodgements up to date before a plan goes to creditors, the company’s total liabilities must not exceed $1 million, and a successful plan doesn’t remit a lockdown director penalty. There are practitioner fees too — ASIC’s 2025 review found median remuneration of around $16,000 for the restructuring stage alone. Our honest SBR explainer covers it in full.

Watch out for cold calls

Builders whose companies appear in published wind-up notices are a target for unsolicited “advisers”. The ATO warns about anyone who contacts you after a creditor starts court action, or who charges a fee based on a percentage of your debt. Check our warning-signs checklist before you sign anything.

What do lenders look at for builders?

Expect questions about the order book, aged debtors, retentions owed to you, major supplier accounts, licensing, and any disputes. A builder with signed contracts and reliable clients presents a strong exit even when the current ATO balance is large.

A note on security of payment

Every state and territory has security of payment laws that give subcontractors rights to claim progress payments and resolve disputes quickly. If slow or withheld payments from a head contractor are behind your ATO debt, ask your lawyer or industry association about using those rights. Recovering what you’re owed may reduce how much you need to borrow — and it strengthens the exit for any loan you do take.

Could funding keep your business building?

If your construction business is viable but the ATO debt is getting ahead of you, see if you qualify. There’s no credit check to enquire, your details stay with one team instead of being scattered to lenders, and a real person who understands progress claims and retentions will call you back. Give us accurate figures for the ATO balance, debtors and any notices — that’s how we find the right structure on the first call.
