Can the ATO tell a credit bureau how much tax my business owes?

The business is still trading. Invoices are going out, staff are being paid, and the work is there. What has not happened for a while is the payment side: a couple of activity statements were lodged but not paid, then an income tax assessment landed on top, and the balance has been sitting there long enough that nobody looks at it any more. Then a supplier asks a question about a credit check, or the broker preparing an equipment finance application mentions something showing against the ABN.

The question that follows is usually the same one: is the ATO allowed to tell anyone what I owe? The answer is yes, in defined circumstances, and those circumstances are published rather than discretionary.

The four criteria, in full

The ATO may disclose business tax debt information to registered credit reporting bureaus where all four of the following are true. You have an Australian business number and are not an excluded entity. You have one or more tax debts of which at least $100,000 is overdue by more than 90 days. You are not engaging with the ATO to manage the debt. And you do not have an active complaint with the Tax Ombudsman about the ATO's intent to report your debt information.

An excluded entity is a deductible gift recipient, a complying superannuation fund, a registered charity or a government entity. Every other ABN holder is inside the population — a company, a trust running a business, a partnership, and a sole trader too.

Two details in the threshold do more work than people expect. It is $100,000 across one or more debts, not one debt of $100,000, so an income tax balance and an unpaid activity statement debt are counted together. And the clock is on the overdue amount: it is the portion overdue by more than 90 days that has to reach the threshold, not the total balance on the account.

"Effectively engaging" is a defined term, not a feeling

The third criterion is the one you can actually control, and the ATO has published what satisfies it. You are effectively engaging if you have a payment plan and you are complying with its terms, if you have applied for release from the tax debt, if you have an active objection against a taxation decision the debt relates to, if you have an active review at the Administrative Review Tribunal or an active court appeal, or if you have an active complaint with the Tax Ombudsman about the debt.

Note the four words attached to the payment plan: and you are complying. A plan that was agreed and then missed is not engagement. Phone calls in which you explain the situation are not on the list either, however reasonable the explanation. The list is made of arrangements that exist on the ATO's systems.

If you are effectively engaging, the ATO will not report the debt even where it is $100,000 or more. That is the mechanism in a sentence: the threshold decides who is in scope, engagement decides who is reported.

The notice, and the 28 days

Nothing is reported without warning. Where the ATO plans to disclose, it sends a written notice of intent. The notice states that you meet the criteria, sets out the information it intends to report, explains the steps available to avoid the reporting, and tells you that you have 28 days from receiving it to act.

What is reported is ABN-level: your ABN, your legal name and business name, your entity type, and the amount of the overdue debt. Six bureaus have registered with the ATO and signed a deed of agreement to receive it — Equifax, Experian, CreditorWatch, Access Intell, Alares and CreditProtect. Sole traders should read that list of reported details carefully, because the legal name attached to a sole trader's ABN is the individual's own name.

It also comes off. The ATO removes the information from the bureau's report when you no longer meet the criteria — that is, when the debt is paid in full or you are effectively engaging with the ATO to manage it.

Two things commonly got wrong

The first is assuming that cash flow trouble is the exception that saves you. The ATO can decide not to report where there are exceptional circumstances outside your control, and it gives family tragedy, serious illness and natural disasters as the kind of thing it means. It then says directly that cash flow issues or financial hardship are not generally considered exceptional circumstances. The reason is not unsympathetic: hardship is precisely what a payment plan is for, and a plan being complied with already stops the reporting.

The second is treating the payment plan as a phone call you make later. If the amount is $200,000 or less, an individual or sole trader can set a plan up in ATO online services and a company through Online services for business, and a registered agent can do it on your behalf. But you have to phone the ATO where the amount is $200,000 or more, where you have defaulted on or cancelled two or more plans in the past 12 months, where you need longer than two years, or where you have had a warning of firmer recovery action in the past six months. If income tax and activity statement debts are both outstanding, they need separate plans — combining the figures is a common reason an online attempt fails.

The general work here is arithmetic before it is anything else. Take the amount that is overdue by more than 90 days, across all accounts, and see where it sits against $100,000. Check whether there is a live arrangement of a kind on the ATO's list and, if it is a payment plan, whether every instalment has actually gone out. And if a notice of intent has already arrived, treat the 28 days as the whole of the available time, because the notice only issues once the criteria are already met.

Credit reporting is one of three firmer actions the ATO names, alongside garnishee notices and director penalty notices; we have written separately on when a director becomes personally liable for a company's PAYG withholding, GST and super. Interest is running underneath all of it, and since 1 July 2025 the general interest charge is no longer deductible, which our earlier piece covers.

This is general information current as at 10 September 2026 and not advice about your business or your debt. Getting lodgments current so the balance is at least a real number, and getting an arrangement in place that meets the definition, is ordinary work — it is what our companies, trusts and bookkeeping service does.
