Quick answer
No. An ATO debt doesn't expire. State limitation laws, including the six-year rule that applies to ordinary business debts, don't apply to tax owed to the Commonwealth, and the tax laws set no cut-off date. The ATO can pause collecting a debt, but it stays on the books, interest keeps building and it can be re-raised years later. Debts end through payment, a plan, release in hardship or a formal insolvency outcome.
Key points
- There's no limitation period on collecting a tax debt. The six-year rule you've heard about is a state law for ordinary debts and doesn't reach the ATO.
- 'On hold' or 'written off' inside the ATO's systems is a decision not to chase for now. It isn't forgiveness, and the debt can be re-raised.
- General interest charge keeps accruing on the unpaid balance, and from 1 July 2025 it's no longer tax deductible.
- The genuine exits are payment, an ATO payment plan, release for individuals in serious hardship, or a formal insolvency outcome.
- Old, unmanaged debts are the ones that drift towards credit reporting and firmer action. Clearing the balance with a loan can be cheaper than waiting.
A letter arrives about a BAS you stopped thinking about years ago. Or you check your ATO account and find an old amount sitting there. The hopeful question follows: surely it’s past the point where they can still chase me for this?
It isn’t. ATO debt doesn’t expire. The six-year limit you may have heard about is a state-law rule for ordinary debts, and it doesn’t apply to tax owed to the Commonwealth. The debt can go quiet, but it stays on the books, interest keeps building, and it can come back at the worst moment. Below is what’s actually true, the four real ways an old debt ends, and how to decide between waiting and clearing it.
Why doesn’t the six-year limit apply to the ATO?
For most business debts, a supplier who waits more than six years to sue loses the right to do so. That comes from the state and territory Limitation Acts. People understandably assume the same clock runs for tax.
It doesn’t. Those state laws don’t reach liabilities owed to the Commonwealth, and the tax laws themselves don’t set an expiry date for collecting a tax debt. Insolvency practitioners Worrells make the point in their note on why tax debts are not time-barred: no state limitation period can extinguish an ATO debt, and the Commonwealth’s financial management rules place a duty on agencies to pursue what is owed unless a specific exception applies.
That’s the legal picture. The practical one is also worth knowing: the ATO’s collection effort is intense right now. The Auditor-General’s June 2026 report found small business accounted for $35.9 billion of the ATO’s $54.2 billion in collectable debt at 30 June 2025, and the ATO accepted recommendations to set reduction targets. An old debt isn’t being forgotten. It’s part of a very large pile the ATO has been told to shrink. See the ANAO report.
What about “on hold” and “written off”?
This is where the myth gets its energy. Owners are told, or see in their account, that a debt has been put on hold or written off, and they reasonably conclude it’s gone.
It hasn’t. In ATO language, an administrative write-off or hold is a decision not to spend effort chasing the debt for now, usually because it wasn’t cost-effective. The liability stays. It can be set against a future refund or credit, and it can be re-raised later, with interest added. We cover how this plays out in our guide to ATO debt on hold, including the way these debts have been added back into account balances since August 2025.
The practical rule: if the debt still appears anywhere in your ATO account, or you’ve been told it was paused, treat it as owed.
What does an old debt cost while it sits there?
Time doesn’t cancel it, but it does add to it. The general interest charge is applied daily to the unpaid balance and compounds. The ATO resets the rate each quarter, and you can see the current figure on its GIC rates page.
Two things make this worse than it used to be:
- It’s no longer deductible. GIC incurred from 1 July 2025 can’t be claimed as a tax deduction, so every dollar of interest costs its full face value. Our page on ATO interest and deductibility explains the change.
- Old debts attract firmer action. A balance that’s been ignored for years, particularly one over $100,000 and more than 90 days overdue, can be disclosed to credit reporting bureaus if you aren’t effectively engaging with the ATO. The ATO’s disclosure rules require a 28-day warning first. Our page on ATO debt and your credit file covers the exceptions.
An illustration, with made-up numbers: a sole trader with a $60,000 income tax and BAS balance leaves it alone for several years because “it’ll time out”. Over that period interest is added every day, none of it deductible, and the original $60,000 is no longer the number that matters. When a lender or the ATO asks for the payout figure, it’s materially higher, and the owner has lost the years in which a plan or funding would have capped the growth.
What are the real ways an old ATO debt ends?
Waiting isn’t one of them. These are:
| Exit | Who it suits | The catch |
|---|---|---|
| Pay it in full | Anyone who can fund the payout from cash, an asset sale or a loan | Needs the cash. Ends GIC and ends any credit-reporting risk |
| ATO payment plan | Businesses that can pay over time and are lodging on time | GIC keeps running while you pay. A default can lead to firmer action |
| Release in serious hardship | Individuals only, where paying would cause serious hardship | Companies, trusts and partnerships can’t apply, and GST, PAYG withholding and super guarantee charge can’t be released. Not common |
| Formal insolvency outcome | Companies where the business can’t be saved | Liquidation, a deed or small business restructuring ends the company’s debt but has practitioner costs and personal consequences for directors |
Two smaller levers sit alongside these. You can ask the ATO to remit some of the interest through GIC remission, and you can read our plain-English take on what “forgiveness” does and doesn’t mean in ATO debt forgiveness. The ATO’s own release from tax debt page lists who is excluded.
We’re a funder, not an insolvency firm, so we’ll be straight: an insolvency outcome is a legitimate option for a business that’s genuinely finished. For one that’s still trading, it’s usually a heavy way to solve something funding can solve.
Is it worth waiting to see if the ATO leaves it alone?
Sometimes owners get lucky. A debt goes quiet for years. But think about what you’re betting on:
- that the ATO won’t re-raise it when you’re about to sell, refinance or apply for a loan;
- that it won’t be set against a refund you were counting on;
- that interest, which is compounding and non-deductible, won’t outgrow the original amount;
- that it won’t be disclosed to credit bureaus once it crosses the threshold.
Against that, the upside of waiting is that you keep your cash for a while. If the debt is small and you’re on a genuine plan, that can be a reasonable choice. For a larger balance with no plan, it rarely is.
When does funding beat waiting?
A loan makes sense when the business is viable, the debt is growing faster than you can pay it down, and you want it gone before it triggers something. The sums to run are simple:
- Get your current statement of account and ask for the payout figure to a specific date.
- Compare what the debt will cost over the next 12 months, with interest that isn’t deductible, against the cost of a loan whose interest may be deductible (ask your accountant).
- Check that you can service the loan from trading, or that a sale or refinance will clear it.
Our payment plan vs loan tool walks through the comparison. If the numbers favour funding, a property-secured loan from $20,000 to $5,000,000 or an unsecured facility for a trading business can be sized to the full payout. Where it’s arranged at settlement, funds can be paid straight to the ATO. Our page on a loan to pay ATO debt explains how it works, and if you’re curious what it would look like for your balance, you can check your options in about a minute.
What should you do this week?
- Log in and look. Check your ATO online account for every debt, including any marked as on hold.
- Confirm what’s lodged. Missing BAS and returns are the fastest way to make a manageable debt a firmer-action one.
- Get the payout figure. Ask for the amount to a set date, interest included.
- Decide between a plan and payout. If you can’t clear it from cash, compare a plan with funding.
- Don’t pay a stranger to “make it expire”. Nothing legitimate does that. Our guide on who to call first covers the red flags.
An old tax debt doesn’t have to stay a worry
Plenty of the owners we speak to have a balance they’ve been quietly carrying for years, hoping the calendar would sort it out. It won’t, but a clear payout figure and a funding option often will. We help business owners with ATO debt every week, and we don’t shy away from the old, awkward ones.
Enquiring takes about 60 seconds and there is no credit check when you enquire, so asking what’s possible leaves your credit file exactly as it is. We don’t send your details to a pile of lenders: a real person looks at your situation and calls you. Please fill the form in accurately, including the debt type and roughly what you owe, so we can match the right option first time.
Frequently asked questions
Is there a statute of limitations on ATO debt?
No. The six-year limitation periods in state and territory Limitation Acts apply to ordinary contract debts, not to tax owed to the Commonwealth. The tax laws don't set a date after which the ATO has to stop pursuing a liability. Legal commentary from insolvency practitioners reaches the same conclusion. Time alone never extinguishes the debt.
Does ATO debt go away after 6 or 7 years?
No. Six years is the usual limit for suing on ordinary debts under state law, and seven years is how long some information stays on a personal credit file. Neither cancels a tax debt. A listing falling off a credit file doesn't mean the debt has been written off.
What happens if the ATO puts my debt on hold?
The ATO has paused chasing it, usually because collection wasn't practical at the time. The debt remains legally owed, can be applied against future refunds and credits, and can be re-raised later with interest. Treat it as unresolved, not finished.
Can the ATO chase a debt that's more than 10 years old?
Generally yes, because there's no expiry date. In practice the ATO weighs cost, the likelihood of recovery and fairness, and reviewers have questioned pursuing very old debts that were left alone for years. Don't rely on that. If you are trading or own assets, an old debt is usually still collectable.
How can an ATO debt actually be cleared without paying all of it?
For individuals, release from the debt in serious hardship, which excludes debts such as GST, PAYG withholding and super guarantee charge. For companies, a formal insolvency outcome such as liquidation, a deed of company arrangement or small business restructuring. Interest and penalties can sometimes be remitted. Each route has costs and consequences, so compare them honestly before choosing.
Does ATO debt keep growing the longer I leave it?
Yes. General interest charge is added daily to the unpaid balance and compounds, and it is no longer deductible for amounts incurred from 1 July 2025. Penalties for failing to lodge or pay can also apply. The ATO publishes the current rate quarterly, so check it against your own balance.
Can I borrow to clear an old ATO debt?
Often, yes. A property-secured or unsecured business loan can be sized to the full payout on your ATO statement of account, and where it's arranged, funds can be paid to the ATO at settlement. Lenders look at whether the business is viable, what security is available and how the loan will be repaid.
