Behind on Tax Payments in Australia? Here's What to Do First

Why This Happens to Good Businesses

Being behind on tax isn't always a sign of a business in trouble. For most small businesses, it starts with cash flow timing — a big job that paid late, a slow quarter, an unexpected GST bill from a higher-than-expected revenue period. Payroll tax, PAYG withholding, and quarterly BAS obligations all land at different times, and for businesses without a dedicated bookkeeper watching the numbers, it's easy for one or two to slip.

Sometimes it's a series of missed BAS lodgements where the business just kept operating and the paperwork piled up. Other times it's a once-off income spike — a large contract, a property sale — that triggered a tax bill nobody planned for.

Whatever the reason, the situation is manageable. The ATO deals with businesses in arrears every day. What matters now is the order in which you act.

Step 1: Don't Ignore It

This sounds obvious but it's where most businesses lose ground. The ATO's General Interest Charge (GIC) compounds daily. What starts as a $15,000 BAS debt at the beginning of the year can be $16,500 or more by the time you open the letter. Ignoring it doesn't pause the clock — it just means the ATO escalates while the debt grows.

More seriously, for PAYG withholding and superannuation guarantee obligations, directors of companies can become personally liable through a Director Penalty Notice (DPN). This means the ATO can pursue you as an individual — not just the company — for those debts. That liability does not disappear if the company is wound up.

Step 2: Get Your Numbers Clear

Before you call the ATO, know exactly what you owe. The ATO's online services (via myGov or the Business Portal) will show your running balance across all tax obligations — income tax, BAS, PAYG, super guarantee charge. If you have a bookkeeper or BAS agent, ask them to pull an ATO account summary for you.

You need to know:

• Which obligations are overdue (and by how much)
• Which periods have lodgements outstanding vs lodged-but-unpaid
• Whether any Director Penalty Notices have already been issued
• The total including GIC that has already accrued

Walking into a conversation with the ATO without these numbers means you can't negotiate effectively. And the ATO will always know more about your account than you do unless you've done your homework first.

Step 3: Lodge Everything First — Pay Later

This is the single most important thing most people don't know: the ATO treats an unlodged return far more seriously than a lodged-but-unpaid debt.

If your BAS returns are up to date but you just haven't been able to pay, the ATO will almost always work with you on a payment arrangement. If your returns haven't been lodged at all, the ATO doesn't know what you owe — and they're much less willing to negotiate. Unlodged returns also expose you to failure-to-lodge (FTL) penalties on top of the debt itself.

Lodge every outstanding BAS, income tax return, and PAYG summary first. Even if you're lodging late. Even if you can't pay yet. Getting lodged is the single most important thing you can do to improve your position with the ATO.

Step 4: Contact the ATO Proactively

Once everything is lodged, call the ATO before they call you. The ATO has a small business tax debt line (13 72 26) and is generally more willing to work with businesses that make first contact. When you call:

• Have your ABN, TFN, and account summary ready
• Know what you can realistically pay — both as an upfront amount and as a monthly repayment
• Ask specifically about GIC remission — partial interest remission is available to businesses with a good history of compliance, and it's worth asking even if you're not sure you qualify
• Request a formal payment arrangement in writing once agreed

The ATO will assess your lodgement history, your payment history, and your current financial position. If you've been mostly compliant in the past and this is a one-off problem, they will generally work with you. If you have a pattern of late lodgements and missed payments, the conversation will be harder.

Step 5: Engage a Registered BAS Agent or Tax Agent

If the debt is substantial, if there are multiple years of outstanding lodgements, or if DPNs have already been issued, don't try to navigate this alone. A registered BAS agent or tax agent can:

• Access your ATO account directly and understand your full position
• Negotiate payment arrangements on your behalf
• Apply for GIC remission formally (which carries more weight than a phone call)
• Ensure all outstanding lodgements are correct before filing — lodging incorrect returns to rush a resolution creates new problems
• Help you understand whether insolvency advice is needed

Registered agents have an ongoing relationship with the ATO and, in many cases, achieve better payment terms than businesses negotiating directly.

Director Penalty Notices Explained

If your business is a company (Pty Ltd), directors need to understand Director Penalty Notices specifically. The ATO can issue a DPN to make directors personally liable for unpaid PAYG withholding and superannuation guarantee obligations.

There are two types:

• Non-lockdown DPN: Issued where lodgements were filed within 3 months of the due date. Directors have 21 days to pay, appoint a voluntary administrator, or appoint a small business restructuring practitioner. Acting within this window prevents personal liability.
• Lockdown DPN: Issued where lodgements were made more than 3 months late, or not at all. The 21-day options are not available — personal liability is locked in. The only escape is paying the debt in full.

This is why lodging on time — even when you cannot pay — is so important for company directors. The personal liability risk from a lockdown DPN can follow a director into future businesses and cannot be discharged through company liquidation.

When It's Beyond a Payment Plan

If your total ATO debt is substantial, the business is continuing to accrue new obligations it cannot meet, or creditors beyond the ATO are involved — a payment plan may not be the right solution. At that point, you need to understand your options: small business restructuring, voluntary administration, or in some cases, an orderly wind-down.

If you're not sure which category you're in, a clean set of accounts is the starting point. See our guide to ATO payment plans for small business if you're at the payment arrangement stage, or read about the difference between liquidation and debt restructuring if the situation is more serious.
