ATO debt on hold: why an old tax debt has turned up in your account balance

Here’s a scene we hear about a lot. The tax return is lodged, a refund is expected, and then the refund shrinks or vanishes. When the bookkeeper logs in, there’s a line on the ATO account nobody remembers: an amount from 2018 or 2019, marked as a debt that was “on hold”.

If that’s you, the short answer is this. A debt on hold is old tax the ATO stopped chasing because it wasn’t worth the effort at the time, but it never went away. Since August 2025 the ATO has been moving these debts back into account balances, and once they’re there the clock starts on interest. Businesses that check now get to choose how to deal with it. The rest find out from a missing refund or a lender’s question.

What exactly is a debt on hold?

When a tax debt looks uneconomical to collect, maybe because it’s small, the business looked like it had nothing to pay with, or the owner couldn’t be found, the ATO can park it. Collection stops. Letters stop. For years, the debt didn’t even appear in the account balance you saw in online services.

What didn’t stop was the legal liability. The ATO’s debts on hold page is clear that a debt on hold is still owed, and that refunds and credits can be used to pay it down. So for many business owners, a debt on hold was an invisible deduction waiting to land on a future refund.

Why is it showing up in my balance now?

The invisibility drew a lot of complaints. The Tax Ombudsman and Commonwealth Ombudsman criticised the way people were learning about debts they couldn’t see, and the ATO changed course. In its notice to tax professionals, the ATO said that from August 2025 it would progressively include debts placed on hold in account balances.

The scale is not small. SmartCompany reported in November 2025 that around 160,000 small businesses were affected, with about $2.9 billion of debts expected to appear. More than half were under $5,000, and the median was $3,450. Some were tiny, including one example of $8.65 from 2014.

How you hear about it depends on the amount:

• $100 or more: you, or your tax agent, should get a letter before the debt is added to your balance.
• Under $100: no letter. It simply appears in the account.
• Already on a payment plan for something else: the ATO has said it will contact you before adding the debt on hold to your balance.

If your accountant changed during the past decade, or you moved address, there’s a real chance the letter went somewhere you never saw it.

The six-month window most owners miss

This is the part worth circling. The ATO says it will keep remitting general interest charge (GIC) for six months after a debt on hold is included in your account balance. After that, GIC applies and compounds daily, and you’d need to contact the ATO to ask for any further relief.

For debts added in late 2025, that six months has already run out. Interest on many of them started in the first half of 2026. And because GIC has no longer been tax deductible since 1 July 2025, it’s a true after-tax cost.

Think of the six months as a free period to decide what to do. Leaving the debt alone past that point turns an old, sleepy amount into a live debt that grows every day.

What about debts from before 2017?

Debts placed on hold before 1 January 2017 are treated separately. The government announced in the 2024–25 Budget that the Commissioner would be given discretion not to offset refunds and credits against these older debts on hold, for individuals, small businesses and not-for-profits. The ATO’s page on changes to offsetting debts on hold still describes it as a proposed measure that isn’t law yet.

In practice, the ATO has paused offsetting against most pre-2017 debts on hold while that change is pending. The Australian National Audit Office’s audit of small business collectable debt looked closely at this pool. The important thing for you: a pause isn’t a wipe. Until the law changes, older debts remain owed. Check with your tax agent before assuming one has disappeared.

How to check your ATO account in ten minutes

You don’t need to wait for a letter. Here’s a quick routine you or your bookkeeper can run:

1. Log in to Online services for business (or online services through myGov if you’re a sole trader) and open your accounts summary.
2. Widen the date range. Debt-on-hold transactions can be years old, so set the filter to show everything from an early date rather than the default recent period.
3. Look for on-hold entries and any new lines dated from August 2025 onwards that you can’t match to a recent BAS or assessment.
4. Check every account. A company can have an income tax account and an activity statement account, and separate entities in a group each have their own.
5. Ask your tax agent to confirm the amount is right. Old debts sometimes relate to lodgements that were later amended, or to entities that were deregistered and reinstated.

Write down the date each debt was added to your balance. That date starts your six-month interest-free window.

Your options once you’ve found it

Option	Works best when	What to watch
Pay it now	The amount is small and correct	Make sure it’s allocated to the right account
Let a refund absorb it	A refund is coming soon anyway	Interest may start before the refund lands
Add it to a payment plan	You’re already on a plan or have other tax owing	GIC keeps compounding on the plan balance
Ask for GIC remission	Interest has started and you have a good reason	Remission isn’t automatic, so put it in writing
Fund it with a loan	It lands on top of a larger ATO debt	Compare the loan’s total cost with GIC honestly

For small debts on hold, paying is almost always the simplest answer. The interesting cases are the bigger ones, particularly when the old debt arrives on top of a current BAS, PAYG withholding or company tax bill. Suddenly the total ATO balance is far larger than you planned for, and that changes which options are open to you. Our ATO payment plan guide covers how plans are set up and what makes them default, and if interest has already been charged, our page on GIC remission walks through how to ask for it back.

Why lenders and buyers care about debts on hold

Most specialist lenders ask for an ATO portal statement when a business applies for funding. Before 2025, debts on hold weren’t in that statement. Now they are. That has a few practical consequences:

• A refinance or new facility can stall while the lender asks what an unexplained balance is. Finding it yourself first means you can turn up with the answer and a plan.
• Selling the business means a buyer’s accountant will see the balance during due diligence, and will want to know who pays it.
• The overall size of your ATO debt matters for things like credit reporting rules and the ATO’s payment plan thresholds, so it pays to know your true total rather than the figure you remember.

None of this is a disaster. A debt you discovered and dealt with is a non-event. A debt the lender discovers is a delay.

A worked example: the electrician’s missing refund

This is an illustrative scenario, not a real client.

An electrical contractor in Newcastle runs a small company with four staff. In 2018 the business went through a rough patch, and a quarter’s worth of activity statement debt, a little under $9k after part-payments, was put on hold.

The owner changed accountants in 2021 and had no idea the amount still existed. In late 2025 the ATO’s letter went to the old accountant’s address. In mid-2026 the company’s tax return showed a refund of around $6k, and the owner was counting on it for a new work ute.

Instead, the refund went towards the old debt. When the new accountant pulled the full transaction history, there was a remaining old balance, plus a current BAS debt of about $35k that the owner was already planning to pay over a few months.

The owner had three choices: a payment plan covering everything, paying the old amount from cash flow, or combining the lot. They chose to fold the whole ATO balance into a single unsecured business loan sized on the company’s turnover and bank statements. The ATO account went to nil, the interest stopped and they had one repayment to budget for. The ute was delayed by a quarter, but the business went into its busy season with a clean ATO statement.

Old tax debt back on the books? Let’s look at it together

A debt you thought was long gone turning up again is frustrating, especially when it lands on a refund you’d already earmarked. We help business owners with tax debt every week, old and new, and we’re one of the few funders who actually like this kind of file.

Where the numbers make sense, we can arrange property-secured funding from $20,000 to $5,000,000, or unsecured and cash-flow options for trading businesses, typically $5,000 to $500,000. If it’s set up at settlement, the money can go straight to the ATO. Our refinance ATO debt page shows how old and current tax debts can be rolled into one facility.

Checking costs you nothing. The enquiry form takes about 60 seconds and there’s no credit check when you first enquire. We don’t send your details to a pile of lenders, so your phone won’t light up with brokers you’ve never heard of. A real person who understands ATO debt reads your enquiry and calls you about your situation.

Please fill the form in accurately: your full ATO balance including any debt on hold, what else you owe the ATO right now and whether you own property. With those three facts we can tell you on the first call whether a loan is the right move, or whether paying it yourself is the smarter play.
