Tax Debt Options for Australian Small Businesses

Owing money to the ATO is more common than most business owners realise. It’s easy to creep up after a quiet quarter, a customer who pays late, or a BAS that gets pushed back a fortnight. 

What makes tax debt different from other debts is how quickly it compounds and how much power sits on the other side of it. The ATO doesn’t need to go to court to start collecting, and in some circumstances it can pursue directors personally.

Before you commit to a path, it helps to see all the options laid out. Below we cover what tax debt actually is, why it grows the way it does, the four broad options available, and how to work out which one fits your situation.

 

<h2>What Counts as Tax Debt for a Small Business

Interest compounds daily

The general interest charge applies to overdue amounts and is calculated daily on a compounding basis, so you pay interest on the interest. For the July to September 2026 quarter, it sits at 11.43% a year. That’s well above most commercial lending, and it doesn’t pause while you sort things out.

Interest is no longer deductible

General interest charge incurred from 1 July 2025 can’t be claimed as a tax deduction. Carrying an ATO debt is now meaningfully more expensive than it was two years ago. 

Directors can become personally liable

Where a company falls behind on PAYG withholding, GST or super guarantee charge, the ATO can pursue directors personally through a Director Penalty Notice. This is the single biggest reason tax debt behaves differently from a supplier account. Company structure does not protect you from it

Large debts can become public

Where a business has an ABN, has at least $100,000 overdue by more than 90 days, and is not engaging with the ATO about it, the debt can be reported to credit reporting bureaus. Once that happens, it shows up when banks, financiers, insurers and suppliers check your file. Businesses that are actively engaged with the ATO about their debt are not reported.

The ATO has powers ordinary creditors don’t

A supplier chasing an invoice has to sue you first. The ATO doesn’t need to.

 

 

What Happens After a Letter of Demand Escalates

One of the most serious escalations after an unanswered letter of demand is a statutory demand. A statutory demand is a formal notice demanding payment of a debt of $4,000 or more within 21 days.

 

Unlike a letter of demand, a statutory demand carries real legal weight. If your company doesn’t respond within that window, whether by paying the debt, negotiating a settlement, or applying to the court to have the demand set aside, the law presumes your company is insolvent.

That presumption lasts for three months and gives the creditor grounds to apply to the court to have your company wound up.

 There’s very little flexibility once a statutory demand has been issued. Courts are strict about the 21-day deadline, and extensions are rarely granted.

If you’ve received one, or you’re worried a letter of demand might turn into one, it’s worth reading our full guide to statutory demand notices and getting advice sooner rather than later.

 

 Can Ignoring a Letter of Demand Lead to Liquidation?
Yes, although it’s rarely a single, direct step. A more accurate way to think about it is that ignoring a letter of demand removes the earliest and lowest-cost opportunity to resolve the debt, which increases the chance that things escalate to a point where liquidation becomes a real possibility.

 

The typical chain looks something like this:

 

• Letter of demand

• Court judgment

• Statutory demand

• Winding up application

• Liquidation

 

 Not every unanswered letter of demand ends this way. Plenty are resolved with a payment plan, a negotiated settlement, or a simple conversation. But the longer a debt goes unaddressed and the more formal the creditor’s response becomes, the closer a company moves toward that outcome.

 If your company is already under pressure from multiple creditors, or you suspect it may be insolvent, it’s worth understanding your options sooner rather than later. Creditors’ Voluntary Liquidation is one path if liquidation does become the right outcome, but it’s not the only one. Small Business Restructuring allows eligible companies to negotiate a plan with creditors while directors stay in control, and it’s often a far better outcome than waiting for a creditor to force the issue.

 

 What to Do Right Now If You’ve Received a Letter of Demand and Haven’t Responded

 

If a letter of demand has been sitting in your inbox, the most useful thing you can do today is stop avoiding it. Read it carefully, note the deadline, and start working through your options, ideally before that date passes.

If your business is under broader financial pressure and the letter of demand is just one part of a bigger problem, it’s also worth reading our guide on what to do if your company can’t pay its debts.
