BAS Overdue? Here's What Happens Next
Overdue BAS lodgements trigger an escalating chain of ATO enforcement actions — from penalties to lockdown Director Penalty Notices. Understanding the timeline is the first step to protecting your business and your restructuring options.
BAS Lodgement Is a Critical SBR Eligibility Requirement
Tax lodgements must be substantially up to date to be eligible for Small Business Restructuring. If your BAS is overdue, you cannot enter SBR until it is brought current. Every day of delay risks crossing the 3-month lockdown DPN threshold, which permanently removes your ability to discharge that liability through restructuring.
Why BAS Matters for SBR
BAS lodgement status directly controls whether you can access Small Business Restructuring.
Tax lodgements must be substantially up to date
Under Part 5.3B of the Corporations Act, a company entering SBR must have tax lodgements substantially up to date. BAS, income tax returns, and PAYG statements all count. If they are not current, the restructuring practitioner cannot accept the appointment.
Lodgement is the gatekeeper
Even if you have a viable business and can afford an SBR plan, overdue BAS blocks access entirely.
Catch up first, then appoint
The fastest path to SBR when BAS is behind: engage a BAS agent, lodge outstanding returns, then appoint a practitioner.
Every day counts
Each day BAS remains unlodged moves you closer to the 3-month lockdown DPN threshold, which cannot be undone.
What the ATO Does When BAS Is Overdue
The ATO follows a predictable escalation path. The further along you go, the harder it is to recover.
Reminder Notices
The ATO sends automated reminders that your BAS is overdue and needs to be lodged.
Failure to Lodge Penalties
Penalties of $313 per 28-day period (per statement) begin accruing, up to a maximum of 5 periods.
GIC Accrual on Unpaid Amounts
General Interest Charge begins compounding daily on any underlying tax liability, currently at ~11% per annum.
Lockdown Director Penalty Notices
If BAS is 3+ months overdue, any DPN issued becomes a lockdown DPN. Cannot be discharged by SBR, VA, or liquidation. Payable in full only.
Garnishee Notices
The ATO can issue notices to your bank or debtors to redirect funds directly to the ATO.
Legal Action and Wind-Up
The ATO may apply to the court to wind up your company, ending the business entirely.
Step 4 is the critical threshold. Once a lockdown DPN is issued, it cannot be reversed. Act before reaching this point.
Consequences of Overdue BAS
The financial and legal consequences compound quickly. Here is what you face.
Failure to Lodge Penalties
$313 per 28-day period
Charged per overdue statement (BAS, IAS, PAYG). Compounds across multiple periods up to 5 units, meaning a single overdue BAS can attract up to $1,565 in penalties.
General Interest Charge (GIC)
~11% per annum
GIC accrues daily on any underlying tax liability from the original due date. From July 2025, GIC is no longer tax deductible, making the effective cost even higher.
Lockdown DPNs
Personal liability — no discharge
The most severe consequence. If BAS is 3+ months overdue, any subsequent DPN is a lockdown type. Directors become personally liable and cannot discharge this liability through SBR, voluntary administration, or liquidation. Only payable in full.
Loss of SBR Eligibility
Restructuring blocked
Tax lodgements must be substantially up to date to enter Small Business Restructuring. Overdue BAS can disqualify a business from this pathway entirely.
The Lockdown DPN Trap
This is the #1 reason to stay current on your BAS. Once you cross this line, the damage is permanent.
What Is a Lockdown DPN?
When BAS or PAYG obligations remain unreported for 3 or more months past the due date, any Director Penalty Notice issued by the ATO becomes a lockdown DPN.
Unlike a standard DPN (which can be resolved through SBR, voluntary administration, or liquidation), a lockdown DPN can only be satisfied by paying the full amount. There is no other way out.
This means directors become personally liable for the company's PAYG and super debts, with no restructuring pathway available to discharge that liability.
Standard DPN
BAS lodged within 3 months of due date
Can be discharged via: SBR, VA, liquidation, or payment
Lockdown DPN
BAS 3+ months overdue when DPN is issued
Only discharged by payment in full. No restructuring. No liquidation. No escape.
This is irreversible. Lodging the BAS after the DPN is issued does not convert it back to a standard DPN.
How to Catch Up on Overdue BAS
A step-by-step approach to getting your BAS current and restoring your restructuring options.
Prioritise the oldest overdue BAS first
Work backwards from the earliest outstanding period. This stops the clock on penalty accrual and prevents further BAS periods from crossing the 3-month lockdown threshold.
Use estimates if records are incomplete
The ATO accepts estimated BAS lodgements. An estimated lodgement is always better than no lodgement. You can revise later if needed.
Lodge even if you cannot pay
Lodging and paying are separate obligations. Lodging on time (even without payment) avoids failure-to-lodge penalties and prevents lockdown DPNs.
Contact the ATO proactively
Call the ATO before they call you. Proactive engagement often results in penalty remission and more favourable payment arrangements.
Engage a BAS agent or tax practitioner
A registered BAS agent can lodge on your behalf, negotiate penalty remission, and help you get current as fast as possible. They can also advise on SBR eligibility.
The fastest path: engage a BAS agent, lodge everything outstanding, then appoint an SBR practitioner. Practitioners can advise on the optimal sequence.
BAS and SBR Eligibility
Understanding the connection between lodgement status and your restructuring pathway.
SBR requires that all tax lodgements are substantially up to date at the time of appointment. This is not discretionary — it is a statutory requirement. If your BAS is behind, the practitioner cannot accept the appointment until lodgements are brought current.
BAS Overdue = SBR Blocked
You cannot enter SBR while BAS obligations remain outstanding. The eligibility check happens at appointment.
Catch Up First, Then Appoint
Lodge all outstanding BAS (using estimates if needed), then engage a restructuring practitioner. This is the fastest viable path.
Practitioners Advise on Sequence
An SBR practitioner can guide you on the fastest sequence to meet eligibility requirements and protect your options.
Do not wait until enforcement action begins. The earlier you catch up on BAS, the more restructuring options remain available to you.
Overdue BAS Is the Biggest Threat to Your Restructuring Options
Get your lodgements current and check whether SBR could help resolve your ATO debt before lockdown DPNs close the door.
