The business is closed — so why is the ATO still chasing me?

Closed is not the same as cleared

The ATO tracks debts by tax accounts and ABNs, not by whether a business is still trading. Cancelling an ABN, ceasing to trade, or even having ASIC deregister a company changes nothing about what was already owed — it just changes who the ATO looks to for payment. What that means depends entirely on how the business was structured, so start there.

Sole traders and partnerships: the debt was always yours

A sole trader and their business are the same legal person. Income tax, BAS and PAYG withholding debts from your trading years are personal debts, exactly like a personal credit card — they follow you into employment, into your next venture, and against your personal assets and tax refunds. The same applies to your share of a partnership's debts (and in a general partnership, potentially all of them). Closing the business removes the income that was servicing the debt without touching the debt itself.

That doesn't make the position hopeless. Payment plans, interest remission and — at the serious end — insolvency options all remain available; the full picture is at sole trader ATO debt.

Companies: what died with the company, and what didn't

A company is a separate legal person, so its ordinary tax debts die with it — if it's properly wound up. But three things routinely survive:

1. Director penalties. Unpaid PAYG withholding, net GST and super (SGC) can be made personally yours through a director penalty notice — and the ATO can and does issue DPNs after a company has stopped trading or been deregistered. Worse, if BAS were lodged more than 3 months late or SGC statements late, the penalty is lockdown: only payment clears it. And because a deregistered company can't be put into liquidation or restructuring, the usual 21-day remittance options for a non-lockdown DPN may be practically out of reach unless the company is first reinstated.
2. Reinstatement. Deregistration isn't necessarily final. ASIC or a court can reinstate a company — and creditors, including the ATO, can seek reinstatement so a liquidator can be appointed and claims pursued. Letting a company with tax debt drift into ASIC deregistration is not the quiet ending it appears to be.
3. Guarantees and other personal strings. Director guarantees to financiers and suppliers, unpaid loans you owe the company (Division 7A loan accounts), and liability questions from how the closure was handled can all outlive the company. Overview: company director liability.

Unlodged final returns: the debt you can't see yet

Many closed businesses have outstanding final BAS, income tax returns or SGC statements. Two reasons to fix that even if you can't pay:

• If you don't lodge, the ATO can raise a default assessment — its own estimate of what you owe, which is frequently higher than reality and harder to unwind than simply lodging accurate figures.
• For directors, lodgment timing controls DPN type. BAS lodged within 3 months of their due dates keep PAYGW and GST penalties in non-lockdown territory; unlodged amounts can be estimated and treated as lockdown. Lodging late is still far better than never.

Getting lodgments current also tells you the real number — and you can't negotiate a debt you can't see.

"I closed years ago and they're only chasing me now"

Common, and legal. Tax debts don't expire — there's no statute of limitations on ATO recovery — and the ATO has spent recent years re-activating old debts it had quietly put on hold, offsetting them against tax refunds or handing them to external debt collectors. If a years-old amount has suddenly resurfaced on your account or eaten a refund, that's its own topic: old ATO debt reappeared. Before paying anything, check the amount is actually yours and correctly calculated — old debts on old accounts are where errors live.

Getting to a clean position

The sequence that works for most people:

1. Map what exists. Every ABN, every tax account, every outstanding lodgment, any notices received. Your accountant or a specialist can pull this from ATO systems quickly.
2. Lodge everything. Accurate figures, even without payment, cap the damage and preserve options.
3. Deal with the debt that's personally yours. A payment plan sized to your new income; interest remission for periods where the debt sat growing; and where the numbers simply don't work, structured insolvency options exist for individuals too.
4. Get advice before ASIC or the ATO makes the next move for you — especially if the company still exists, or a DPN could be coming. Not sure where you sit? Two minutes with what's my situation? will narrow it down.
