What Happens If You Ignore ATO Debt? Don’t Risk Your Future

Falling behind on your tax obligations is more common than many realise. Job losses, illness, natural disasters and cash‑flow hiccups can leave anyone – from sole traders in Brisbane to families in Perth – staring down an unexpected Australian Taxation Office (ATO) bill. The National Debt Helpline notes that many people get into tax debt because of redundancy, illness or other issues, and stresses that you’re not alone. Yet one of the worst things you can do is ignore the problem. Tax debts won’t disappear; interest compounds daily, refunds are seized, and the ATO will eventually use its full powers to collect. This guide explains what happens if you ignore ATO debt and how you can take control before matters spiral into legal action.

Why Ignoring Tax Debt Is Risky

Interest grows every day

When you don’t pay on time, the ATO automatically adds a general interest charge (GIC) to your unpaid amounts. Interest compounds daily, meaning your debt grows larger each day it remains unpaid. An Inspector‑General of Taxation report warns that compounding GIC can cause small debts to balloon and sometimes exceed the original tax owed.

Refunds and credits are offset

The ATO is legally obliged to use any future tax refunds or credits – including credits from other government agencies – to pay off your outstanding debt. If you count on a refund to cover expenses or child support, you may find it disappears.

You’ll be contacted and referred to collection agencies

Soon after your due date, the ATO will reach out via SMS, myGov messages, letters or phone calls to remind you. If you still don’t respond, your debt may be referred to an external collection agency, which will contact you directly. Ignoring those calls can damage your credit rating and lead to further enforcement.

Firmer action kicks in when you refuse to engage

The ATO reserves firmer actions for taxpayers who refuse to engage, default repeatedly on payment plans or deliberately avoid paying. Such behaviour triggers targeted measures including:

• Garnishee notices. The ATO can instruct your employer, bank or people who owe you money to pay part of your income or funds directly to the ATO. Garnishees can apply to salary, bank accounts or property sale proceeds.
• Director penalty notices (DPNs). Company directors become personally liable for unpaid PAYG withholding, GST or superannuation. A DPN gives 21 days to pay before personal divisible property are pursued.
• Disclosure to credit reporting bureaus. Business tax debts may be reported to credit bureaus if you meet the criteria. You’ll receive a notice of intent to disclose and can stop it by engaging with the ATO.
• Other enforcement measures. These include directions to pay super guarantee charges, departure prohibition orders preventing overseas travel, freezing orders over divisible property and securities.

Legal action escalates your risk

If firmer actions don’t resolve the debt, the ATO can initiate legal proceedings. While we couldn’t access the full ATO page due to technical issues, our previous research shows the ATO may file a statement of claim or summons, seeking a judgment debt. Unpaid judgment debts can lead to a bankruptcy notice, requiring payment within 21 days, and eventually a creditor’s petition to bankrupt you or wind up your company. Bankruptcy can result in losing control of your divisible property, restrictions on travel and credit, and long‑term credit score damage. Even if the ATO obtains a judgment, you can still negotiate a payment plan or seek an instalment order, but your options narrow significantly.

Stress on mental health and relationships

Debt problems rarely exist in isolation. The ATO’s personal crisis support page acknowledges that mental health and wellbeing may make it hard to meet tax obligations and encourages taxpayers to contact them early. The Law Council of Australia points out that natural disasters, loss of loved ones, chronic health conditions and financial crises – all exacerbated by the pandemic – have made many Australians vulnerable. Left unchecked, tax debt can strain relationships, impact your business and cause anxiety or depression.

Real‑World Examples: What Happens When You Ignore

In mid‑2025 the ATO announced it was stepping up efforts to recover around A$50 billion in collectable debts, mainly from small businesses. ATO Commissioner Rob Heferen told a Senate committee that the agency is moving urgently to use all available powers, including garnishee notices, director penalty notices and winding‑up actions. CPA Australia warns that business owners treated tax debt like an interest‑free loan during the pandemic but that the ATO is now recovering those amounts through credit reporting, director penalties, garnishees and liquidation. More than 30,000 businesses have defaulted on tax debts worth over A$100,000.

Accountants say that ignoring ATO letters is the worst move. Early contact gives you more options, but once the ATO starts winding‑up proceedings your choices are limited. Partners at accounting firms report that the ATO is less willing to grant payment plans or remit penalties when taxpayers have avoided contact. However, they also note that when clients engage early and present a realistic plan, the ATO still offers 12‑ to 24‑month payment plans and even remits interest.

Steps to Take Before It’s Too Late

Ignoring ATO debt is not a strategy; it simply transfers control to the tax office. Here are proactive steps to take instead:

1. Do a budget and start paying what you can

The National Debt Helpline advises first working out what you can afford by completing a simple budget. If you can pay even a small amount, start paying and contact the creditor immediately. If you genuinely cannot afford anything, call the Helpline for advice.

2. Contact the ATO as soon as possible

The longer you wait, the fewer options you have. The NDH emphasises contacting the ATO early; there is a dedicated financial hardship team that can arrange long‑term payment plans, temporarily stop interest or waive fines. The ATO will want details of your income, expenses, divisible property and liabilities, so prepare these ahead of the call.

3. Set up a payment plan

A payment plan spreads your debt into manageable installments. The ATO’s payment plan estimator helps you calculate upfront payments and monthly installments and shows how paying more reduces interest. Choose an amount you can stick to – failing to meet the plan will trigger firmer actions like garnishees.

4. Apply for interest or penalty remission

If unforeseen circumstances delayed your payment, ask the ATO to remit some or all of the GIC. Provide evidence (medical certificates, disaster declarations) and explain the steps you took to address the debt. Dispute Assist can help people with vulnerabilities, and case studies show that interest and penalties are remitted when taxpayers provide proof.

5. Request release on grounds of serious hardship

If paying your tax debt would leave you unable to afford basic necessities – food, accommodation, medical treatment or education – you can apply for serious financial hardship release. The ATO will consider your household income and expenses and may release some or all of your debt. Even if your application is refused, you have the right to appeal the decision to the Administrative Appeals Tribunal.

6. Seek an independent review if you disagree

If you can’t reach an agreement with the ATO or believe their decision is unfair, you can seek a free review through the Taxation Ombudsman. The Ombudsman can assist with payment extensions, review recovery actions, investigate delays and make sure the ATO considered all relevant information.

7. Talk to a financial counsellor

Financial counsellors offer free, confidential guidance and can help you negotiate with the ATO, prepare budgets and explore options like debt agreements or bankruptcy. You can call the National Debt Helpline on 1800 007 007 (weekdays 9:30 am–4:30 pm) or use live chat. Counsellors can also help you get mental health support if debt anxiety is overwhelming.

8. Keep filing and setting aside money

Even if you can’t pay, always lodge your tax returns and BAS to avoid penalties. NDH advises lodging returns, setting aside money for untaxed income and keeping good records. The ATO recommends businesses use digital tools, set aside money for GST and PAYG withholding and pay on time to avoid interest. Individuals should put aside money for contractor income, capital gains and investment earnings.

9. Consider formal debt arrangements only as a last resort

If you’ve tried all other options and still can’t pay, you might consider a Part IX debt agreement or bankruptcy. Debt agreements are an act of bankruptcy and should only be considered as a last resort. They may be suitable if you have divisible property to protect, need to remain a company director or can afford repayments. Agreements generally run for up to 3 years, with up to 5 years possible in certain circumstances. but if creditors reject your proposal or you default, they can petition to bankrupt you. Seek independent advice before entering any insolvency arrangement.
