ATO payment plan refused or defaulted? What happens and what to do next

Can the ATO really refuse a payment plan?

It can. Payment plans are an arrangement the ATO agrees to, not a right. Most straightforward requests for modest debts are accepted, particularly online, but the ATO looks harder when something in the picture worries it. In our experience the most common sticking points are:

• Outstanding lodgements. If returns or activity statements haven’t been lodged, the ATO can’t see the whole debt.
• Instalments too small. A plan that would take years to make a dent may be declined, especially where GIC is growing faster than the repayments.
• Past defaults. A history of broken plans makes the ATO less willing to agree again.
• Debts above the online limit. For debts of $200,000 or more, the ATO generally wants financial information before agreeing.
• Viability doubts. If the business looks unable to pay new tax as well as the old, the ATO may conclude a plan simply delays the inevitable.

What makes a plan default?

The ATO’s own list is short and specific. A plan can default if you:

1. miss an agreed instalment by its due date;
2. don’t act on an arrears letter; or
3. don’t pay an additional tax obligation — a new BAS, an assessment — on time.

That third point catches many businesses. You can make every instalment perfectly and still default because next quarter’s BAS went unpaid.

What happens after a default?

The ATO says that when a plan defaults, the whole overdue balance becomes immediately payable and it may take firmer action. That can include:

Action	What it does
Garnishee notice	Requires your bank, customers or merchant facility provider to pay money owed to you directly to the ATO
Director penalty notice	Starts a 21-day clock on directors’ personal liability for GST, PAYG withholding and super
Credit-reporting disclosure	For $100,000 or more overdue by more than 90 days, after a 28-day warning
Statutory demand	Requires the company to pay or enter an arrangement within 21 days

A default also affects future options. The ATO’s interest-free plan for small business requires no more than one plan default in the previous 12 months.

What should you do in the next few days?

1. Read the letter carefully and note any dates.
2. Pull your statement of account so you know the exact balance now due.
3. Call the ATO. Explain what happened and what has changed. Renegotiation is sometimes possible, especially if you call before firmer action begins.
4. Lodge anything outstanding — it’s the first thing the ATO will ask about.
5. Get free advice from the Small Business Debt Helpline on 1800 413 828 if you’re unsure.
6. Look at the alternatives below, quickly.

What are the alternatives if a new plan isn’t possible?

• A secured ATO plan. Where a standard arrangement can’t be reached, the ATO may accept security — preferably a registered mortgage over freehold property or an unconditional bank guarantee from an Australian bank — for an instalment arrangement or deferral.
• Funding. A loan pays the ATO in full, ends the default, and replaces it with a lender’s terms. Property-secured loans run from $20,000 to $5,000,000; unsecured options typically $5,000 to $500,000. See loan to pay ATO debt.
• A split. Fund the director-penalty taxes (GST, PAYG withholding, super) and ask the ATO for a plan on the income tax only.
• Independent advice. If the business can’t sustain any repayment, speak to a free financial counsellor or a registered liquidator you’ve checked — before firmer action, not after.

Why did the plan fail — and will a loan fail the same way?

It’s worth asking honestly. If the plan defaulted because a single large customer paid late, or a seasonal dip hit harder than expected, funding with a longer term may fix it. If it defaulted because every quarter adds new tax debt, a loan will meet the same fate unless something changes in pricing, costs or tax set-asides. A lender will ask the same question, so having an answer helps both of you.

How do you rebuild a payment plan the ATO will accept?

If you want another plan with the ATO, approach it as if you were applying to a lender:

1. Lodge everything outstanding before you call.
2. Pay something now if you can — it shows commitment and reduces the balance.
3. Propose instalments you can genuinely meet, with a simple budget showing new BAS and super as well.
4. Explain the default in one or two sentences and what has changed.
5. Offer direct debit so instalments can’t be missed by oversight.
6. Consider offering security for larger debts.

If the ATO still says no, that’s a strong signal to look at funding or independent advice quickly, before firmer action builds.

Don’t let new debt build up meanwhile

While you sort out the refused or defaulted plan, keep lodging and paying new BAS, PAYG withholding and super on time. New debt makes every option harder — and for directors, late-reported GST and withholding can add locked-down amounts to the problem.

Ready to look at funding?

If your ATO plan has been refused or has defaulted and the whole balance is now due, start a quick enquiry. There’s no credit check to enquire, your details stay with one team rather than being sent out to a list of lenders, and a real person will call to work out whether funding or another path fits. Please tell us about the default and any notices accurately — it helps us act fast.
