How to talk to the ATO about a business tax debt

Most owners put off the call to the tax office for the same reason: they expect a lecture, or worse, a demand for the full amount by Friday. In practice, the first conversation with the ATO about a business debt is usually businesslike and procedural. The officer wants three things: everything lodged, a believable explanation, and a payment proposal you can actually keep. Turn up with those and the call is often over in twenty minutes.

This guide is about that conversation: how to prepare for it, what to say, what to ask for, and how to keep the arrangement alive afterwards. For the wider picture of every option, including finance, our guide on how to deal with an ATO debt covers the ground.

Why does the timing of the call matter so much?

The ATO treats a business that picks up the phone very differently from one that goes quiet. Early on, you’re a taxpayer who needs time. Once letters go unanswered, you become a collection case, and the toolkit shifts: a garnishee can be issued to your bank or a customer who owes you money, directors can receive penalty notices, and the debt can be passed to the credit bureaus.

That last one deserves attention. The ATO can report an unpaid business balance once it reaches $100,000 and stays outstanding beyond 90 days, provided the business hasn’t been engaging with it. It writes first and gives 28 days to act. Keep instalments flowing on an agreed plan and you sit outside that net. A debt sitting on your company’s credit file makes every future loan, lease and supplier account harder, so a phone call now protects a lot more than this quarter. Our guide on how the ATO reports tax debts to credit bureaus explains the process step by step.

The best time to call is before the due date. The second best is today.

What should be on the desk when you ring?

A short burst of preparation sets the tone for everything that follows. Gather these first:

Have ready	Why it matters
Every BAS and income tax return lodged	Plans generally aren’t offered while lodgements are outstanding
The exact balance from Online services for business	Quoting a figure from memory makes you sound unsure of your own position
Which accounts the debt sits in	Activity statement and income tax debts are separate accounts and may need separate plans
A short cash flow forecast	For larger debts the ATO may ask how you arrived at your offer
A one-line reason the debt built up	A lost customer, a bad debt, illness, a slow season; the ATO wants context, not a story
What’s changed since	Price rises, a new contract, a cost you’ve cut; this is what makes the plan believable
Your ABN, your myGov or Online services access and a pen	Identity checks take time; notes protect you later

If a return or BAS is missing, lodge it before the call, even if you can’t pay a cent of it. Lodging is separate from paying. An unlodged BAS can also matter personally for company directors, because unreported PAYG withholding and super can lock in director penalties that can’t be escaped later by placing the company into administration. The details are in our guide on what a director penalty notice means for you.

How do you work out a realistic offer?

This is where most arrangements fail, months after the call. Owners under pressure offer a number that sounds responsible rather than one their bank account can sustain. Then a quiet month hits, an instalment bounces and the plan defaults.

Work it out from cash, not hope:

1. Take your average monthly bank receipts over the past three to six months.
2. Subtract the payments that can’t move: wages, super, rent, loan repayments, core suppliers, and your own minimum drawings.
3. Subtract the BAS and PAYG instalments that will keep arriving while the plan runs. The ATO will expect new obligations to be paid on time alongside the old debt.
4. What’s left is the ceiling. Offer something below it, with a margin for a bad month.

A simple weekly forecast makes this far easier. Our guide on how to build a 13-week cash flow forecast shows a layout you can finish in an afternoon, and the ATO debt calculator shows how instalment size and timeframe change the total.

Weekly or fortnightly instalments often suit a business better than monthly. They match how cash actually arrives and make each payment smaller and less likely to bounce.

Online, by phone, or through your tax agent?

Online. Where a business owes $200,000 or less, a plan can usually be set up through Online services for business without speaking to anyone. If your proposal fits within the ATO’s standard parameters, this is the quickest route.

By phone. Above that amount, or when you need a longer timeframe than the online tool will accept, you’ll be talking to a person. Expect questions about your cash position, what other debts you carry, why the debt arose, and whether you’ve considered other ways to pay, including borrowing. For larger debts, the ATO may ask for bank statements, a profit and loss statement or a forecast before agreeing.

Through a registered tax agent. Agents can set up plans for clients, though there are limits; the agent channel won’t accept a new plan online for an account that already has one, or where that account has seen three or more defaults within the last 24 months. An agent is also now the channel for requests to remit the general interest charge: since January 2026, agents lodge these through their own portal. If your debt grew because of something genuinely outside your control, such as the sudden collapse of a major customer or serious illness of a key person in a small business, ask your agent whether a remission request is worth making.

What should you actually say on the call?

Keep it short, factual and forward-looking. Something along these lines works:

• Who and what: “I’m calling about the activity statement debt on our ABN. Everything is lodged. The balance is $48,600.”
• Why: “We lost our largest customer in March and it took four months to replace the revenue.”
• What’s changed: “We’ve signed two new contracts and cut a part-time role. Receipts are back to where they were last year.”
• The offer: “We can pay $1,900 a fortnight while staying current with new BAS. That clears it in about 13 months. I can send a forecast showing how.”
• The ask: “Can we set that up today, and can you confirm what happens to the general interest charge while the plan runs?”

Then listen. If the officer pushes for a shorter term, ask what they need to see to accept yours rather than agreeing to a number you can’t sustain. It is far better to negotiate for an extra ten minutes than to default in three months.

Things to avoid: promising a lump sum you haven’t secured, guessing figures, blaming the ATO, and agreeing to anything you haven’t checked against your forecast. And note the officer’s name, the date, the reference number and the precise terms you settled on.

If the conversation suggests a loan could clear the debt faster or for fewer total dollars, you can send us a short outline and a person will talk you through what’s realistic, and asking won’t touch your credit file.

How do you keep the arrangement alive afterwards?

Getting a plan is half the job. Keeping it is the other half, and the ATO is unforgiving about silent defaults.

Lodge and pay new obligations on time. A plan covers the old debt. A new BAS left unpaid while the plan runs is one of the fastest ways to have it cancelled.

Set up direct debit. It removes the risk of forgetting an instalment. If your plan is currently paid by credit card, act now: the ATO has said card payments will stop after 30 November 2026, and card payments attempted after that date will fail. A failed instalment can push a plan into arrears or default. Switch to direct debit, BPAY or another method before your next instalment due after that date.

Call before you miss, not after. If an instalment looks like falling short, contact the ATO first and ask to vary the plan. A request to adjust is treated very differently from a dishonoured payment with no explanation.

Remember the interest is no longer deductible. From the 2025–26 income year onwards, interest the ATO charges on late tax (GIC and shortfall interest alike) stopped being deductible. A long plan therefore costs more in real terms than it once did, which is why some owners revisit whether to refinance the balance. Our comparison of a business loan vs an ATO payment plan sets out how to compare them fairly.

A worked example: two owners, the same debt

This is an illustration, not a real case.

Two Brisbane businesses each owe $85,000 on their activity statement accounts after a slow year.

Owner A leaves the reminder letters unopened for three months. By the time they call, the debt has crossed 90 days overdue, a disclosure warning has arrived, and two quarterly BAS are unlodged. The ATO won’t discuss a plan until the lodgements are done. While the accountant catches up, a garnishee notice lands on the business bank account.

Owner B calls two weeks before the due date. Everything is lodged. They explain a large customer paid 70 days late, show that receipts have recovered, and offer $1,650 a week through direct debit. Because the debt is under $200,000, the plan is set up online that afternoon. Six months later, a bank refinances the balance on a term loan, because the owner’s credit file is clean and the plan has never missed.

Same debt, same industry. The difference was a phone call and an afternoon of paperwork.

What if the ATO won’t accept what you can afford?

Sometimes the gap between what the ATO wants and what your cash flow can carry is too wide. You have a few realistic paths:

• Ask what evidence would change the answer. A detailed forecast or accountant’s letter sometimes shifts an officer’s view.
• Pay a lump sum to shrink the debt, then put the balance on a plan the ATO will accept.
• Refinance part or all of the debt. Banks will lend to businesses with ATO debt when the arrangement is current and the business services comfortably, and when you fit their criteria that is often the cheapest money available. Where a bank declines, specialist lenders offer tax debt loans, either unsecured on your trading figures or secured against property. Our page on ATO tax debt business loans walks through what lenders look at.
• Get advice early if the business can’t recover. A registered liquidator or restructuring practitioner can explain options while you still have choices, especially if director penalties are possible.

Ready to look at clearing the debt rather than carrying it?

Plenty of the owners who come to us have an ATO balance hanging over them, and it doesn’t put us off. Sometimes a plan is the right answer and we’ll say so. Other times, rolling the debt into one loan with a clear end date removes the interest that can no longer be claimed, keeps your credit file clean and stops the letters.

Telling us your situation takes about a minute, and simply enquiring leaves your credit report untouched. Your details stay with us rather than being shopped around to a crowd of lenders, so your phone stays quiet. A member of our team looks at your numbers and rings you to talk it through. Please give us the real balance and your genuine monthly figures; accurate details let us point you at the right option on the first call.
