A $636 Company Doesn't Shield Its Directors From the Tax Office

What the $636 company fee buys, and the tax debts it leaves out

ASIC charges $636 to register a proprietary company with share capital from 1 July 2026, according to ASIC's fee data. NowInfinity's indexation notice puts the 2025-26 fee at $611. Most founders pay it for limited liability, so a failed business takes the company's assets and leaves the house alone. For trade creditors, suppliers and lenders who hold no guarantee, that is broadly how it works.

Tax law cuts a hole in that protection. The ATO says a director can become personally liable for the company's unpaid PAYG withholding, GST and super guarantee charge. The Inspector-General of Taxation and Taxation Ombudsman says the ATO issued more than 84,000 Director Penalty Notices in 2024-25, up 136% on the year before, and has opened a review of how the ATO uses them.

A director signs a personal guarantee on a lease or loan. The tax liability needs no signature. It comes with the job title, and it attaches to GST, PAYG withholding and super, money the company holds for the ATO and its staff.

Big business still leaves nearly a third of small-business invoices unpaid at 30 days

The Payment Times Reporting Regulator tracks how large companies pay their small suppliers. In the six months to December 2025, they paid 69.8% of small-business invoices within 30 days, the regulator's August 2026 update shows, which left nearly a third waiting longer.

The averages look tidy. The regulator puts the average common payment term at 29 days, and large payers meet it on average. Paying 95% of small-business invoices took 55 days.

Some industries run slower again. Manufacturing took 68 days to pay 95% of its small-business invoices, the regulator found.

Late invoices measured in days of cash

A supplier on 29-day terms who gets paid at the 55-day mark carries the customer for an extra 26 days. On our arithmetic, a business billing $250,000 a year that waits 55 days for its money has about $38,000 owing to it at any time. At 29 days the same business would have about $20,000 out, so the slow tail ties up roughly $18,000 more of cash the owner has already earned.

Xero's own research, drawn from its Small Business Insights data, puts the average time to be paid at 22.9 days in the June 2026 quarter, with invoices paid 6.0 days late on average. Xero's figures cover all of its small-business customers' invoices and the regulator's cover only large payers, so the two sets do not combine.

Monthly bookkeeping ($1,400) adds up to $16,800 over a year at Going Rate's prices. That pays someone to chase overdue invoices, reconcile the bank account and lodge the activity statement on time. Customers still pay when they choose.

Small-business debt ends up with the Tax Office

Financial Counselling Australia says its Small Business Debt Helpline assisted a record 7,237 small businesses in 2025-26, and ATO debt appeared in 66% of those cases. The release warns that when business lending goes wrong, owners can lose the business and their home.

In its February 2026 release on demand during 2025, Financial Counselling Australia put the median ATO debt among the helpline's clients at $70,000. That figure describes businesses that sought help, not all small businesses. At Going Rate's prices, $70,000 equals 50 months of monthly bookkeeping ($1,400) and about 11 times a year of business insurance ($6,300).

No source here measures how many of those debts began with a slow customer. A business short of cash can pay wages and suppliers first and leave the GST and PAYG it collected for the ATO sitting in the account. The director penalty regime reaches that money.

Director penalty notices and the warning signs before them

CreditorWatch data reported by Accountants Daily puts the insolvency rate over the past 12 months among businesses with ATO debts over $100,000 at 21.9%. By CreditorWatch's measure, a single registered trade payment default lifts a business's likelihood of insolvency to more than 10 times the national average over the following 12 months.

CreditorWatch also found late payments at a six-year high in April 2026, IT Brief reported. In food and beverage services, 11.37% of invoices were more than 60 days past due.

Hall & Wilcox reports that the ATO has issued some notices in error, because its systems did not always check whether a company had already entered external administration, and that the firm is starting to see those notices revoked. A director who receives a notice should still respond. The ATO gives 21 days from the notice to take one of the options to remit the penalty, so advice from an accountant or insolvency practitioner has to come inside that window.

Lodging on time keeps a director's options open

The ATO says the options to remit a director penalty depend on when the company reported the debt. If the company reports unpaid PAYG withholding or GST within 3 months of the due date, the penalty can be remitted within 21 days of the notice by paying in full, appointing an administrator or small business restructuring practitioner, or winding the company up. If the company reports later than that, or never, only paying the debt in full remits the penalty. For super, the cut-off is the SGC due date.

That makes bookkeeping a liability control as well as an admin cost. One month of outsourced bookkeeping ($1,400) costs about 2.2 times the $636 company fee at Going Rate's prices, and a year of it about 26 times.

ASIC applies the same logic at a smaller scale. A proprietary company pays a $342 annual review fee, ASIC's fee data shows, plus a $428 late fee if it pays more than a month late. Missing a date costs more than meeting it, for the ASIC review and the BAS alike.

The other personal obligations a director signs up for

A company that rents premises adds a second layer of personal exposure. Landlords can ask directors to guarantee the lease, and make-good clauses can require the tenant to remove a commercial fitout ($510,000) and return the space at the end. Paying for a lawyer to review a commercial lease ($3,300) before signing costs about five times the company fee at Going Rate's prices.

Lenders want security too. The Reserve Bank says the share of SME credit that is unsecured has stayed below 5% in recent years. Insolvency firm Jirsch Sutherland, citing Alares data, reports that court actions by lenders outside the big four banks hit a record in the September 2026 quarter. One of its case studies is a transport business director who personally guaranteed a $75,000 short-term loan.

Formal failure is still uncommon. ASIC counted 14,153 companies entering external administration for the first time in 2025-26, 0.38% of registered companies. A director's first-year budget should cover business insurance ($6,300), a bookkeeper who reports the BAS inside 3 months, a lease review and enough cash to carry customers who pay at 55 days.
