Avoiding ATO Penalties: What Happens When You Miss Your BAS Due Date in 2025
With penalty units increasing from $313 to $330 as of November 2024, understanding the consequences of late Business Activity Statement (BAS) lodgements has never been more important for protecting your business’s financial health and reputation. This guide will help you navigate the 2025 BAS landscape, understand potential penalties, and implement strategies to ensure you remain compliant with ATO requirements.
Understanding the Importance of BAS and its Obligations
Business Activity Statements (BAS) are essential tax reporting tools for GST-registered businesses in Australia. They allow businesses to report and pay obligations such as Goods and Services Tax (GST), Pay As You Go (PAYG) withholding, and PAYG instalments. Staying on top of your BAS obligations ensures effective cash flow management, compliance with the Australian Taxation Office, improved eligibility for loans and contracts, and confidence in financial planning.
Since October 2024, the ATO has intensified enforcement efforts, making it crucial to lodge your BAS on time. Missing a BAS due date can result in immediate penalties, emphasizing the need for timely compliance.
Due Dates for Lodging and Paying Your BAS in 2025
Understanding your reporting and payment cycles is vital. The due dates for lodging and paying your BAS depend on whether you report monthly, quarterly, or annually.
Quarterly BAS Due Dates
If lodging yourself:
Quarter 1 (July–September): 28 October 2025
Quarter 2 (October–December): 28 January 2026
Quarter 3 (January–March): 28 April 2025
-Quarter 4 (April–June): 28 July 2025
If lodging through a registered tax or BAS agent:
Quarter 1: 25 November 2025
Quarter 2: 25 February 2026
Quarter 3: 26 May 2025
Quarter 4: 25 August 2025
Monthly BAS Due Dates
For businesses with a GST turnover above $20 million or those mandated by the ATO, monthly reporting applies. Monthly BAS is due by the 21st day of the following month. For example, the July monthly BAS must be lodged and paid by 21 August 2025.
If a due date falls on a weekend or public holiday, lodgement and payment can be made on the next business day.

Consequences of Missing Your BAS Due Date
Failing to lodge your Business Activity Statement (BAS) by the due date can lead to several consequences, whether you are lodging your own BAS or working with a registered agent. Missing deadlines for BAS reporting, whether quarterly or monthly, can result in significant financial and reputational repercussions.
Failure to Lodge (FTL) Penalties
The ATO imposes Failure to Lodge penalties based on your business’s annual turnover and how overdue the lodgement is. As of November 2024, penalty units have increased to $330 each. For small entities with an annual turnover under $1 million, one penalty unit ($330) applies for every 28 days late, capped at five units ($1,650). Medium entities with a turnover between $1 million and $20 million incur two penalty units ($660) per 28 days late. Large entities with a turnover over $20 million face five penalty units ($1,650) per 28 days late. These penalties apply regardless of whether you lodge BAS quarterly or annually.
Additional Financial Impacts
Late lodgement triggers other consequences such as General Interest Charges (GIC) on unpaid tax liabilities, including amounts related to luxury car tax, wine equalisation tax, and fuel tax. It can also lead to the loss of tax compliance status, affecting eligibility for government contracts or benefits for not-for-profit bodies. Strain on cash flow may occur due to mounting penalties and delayed payments, potentially delaying any BAS refund you may be entitled to. Additionally, reputational damage with suppliers or lenders can arise if you fail to pay GST or meet other obligations like submitting payment summaries on time.
To avoid these issues, it’s crucial to lodge BAS by the required due date and consider strategies like making payments early when possible. Whether preparing a December activity statement or managing a more complex reporting cycle, staying proactive helps maintain compliance and protects your business’s financial health.
ATO’s Compliance Focus in 2025
For this year, the ATO has identified key compliance areas:
Misuse of small business concessions.
Incorrect use of business funds for personal purposes.
Non-compliance in industries like ride-sourcing services.
Staying informed about these focus areas can help businesses proactively address potential issues before they escalate.
Strategies to Avoid Missing Your BAS Due Dates
Avoiding penalties begins with proactive planning. Here are practical strategies:
Set Calendar Reminders for Key Dates
Mark all relevant lodgement periods in a dedicated calendar. Set multiple reminders—14 days, seven days, and three days before each due date—to avoid last-minute stress.
Maintain Accurate Records
Organized bookkeeping simplifies GST reporting and ensures all transactions are accounted for during your reporting period. Consider using accounting software that tracks GST obligations automatically.
Engage a Registered Tax or BAS Agent
Working with a registered tax professional or BAS agent provides:
Extended due dates for quarterly activity statements
Expert guidance on GST reporting and payment cycles
Reduced risk of errors during preparation
Strategic advice tailored to your business’s annual tax period
Leverage Financial Management Software
Modern software solutions streamline GST tracking, PAYG instalments, and other aspects of BAS reporting. Many platforms also include automated reminders for lodgement periods.
What If You Miss a Lodgement Period?
If you’ve missed a due date, take immediate action to minimise penalties and maintain compliance. Lodge your BAS immediately, whether it’s monthly BAS reporting or annual reporting, as the sooner you lodge, the fewer penalties you’ll incur. Contact the ATO to explain any extenuating circumstances that caused the delay, especially if your business is voluntarily registered for GST. Pay any outstanding amounts promptly to reduce additional interest charges and request penalty remission by providing documentation supporting your request if applicable. Finally, review your processes to identify gaps in your current system and implement improvements to ensure timely submissions, whether you lodge BAS annually or follow a monthly reporting cycle.
