How to Avoid Penalties for Non-Compliance with STP Phase 2 Reporting in 2025
Avoiding penalties for non-compliance with Single Touch Payroll (STP) Phase 2 reporting in 2025 is a critical priority for Australian businesses. With the Australian Taxation Office (ATO) now fully enforcing STP Phase 2 requirements, employers must ensure their payroll systems and processes meet the expanded reporting obligations. Non-compliance can lead to financial penalties, increased scrutiny, and disruptions to business operations. This article provides a clear roadmap to help businesses avoid penalties by understanding STP Phase 2 requirements and implementing effective compliance strategies.
What Is STP Phase 2 and Why Does It Matter?
STP Phase 2 builds on the original Single Touch Payroll framework introduced in Australia to simplify payroll reporting. This phase requires employers to submit additional payroll data to the ATO with each pay run, including detailed information about employees’ salaries, wages, super contributions, and tax treatments. The goal is to streamline reporting across multiple government agencies, reducing the need for separate submissions such as payment summaries or group certificates
Key Changes in STP Phase 2 Reporting
Under STP Phase 2, employers must provide:
Detailed income breakdowns: Categorising payments such as regular wages, overtime, allowances, and salary sacrifices.
Employment conditions: Reporting whether employees are full-time, part-time, casual, or working under concessional reporting options.
Tax treatment codes: Specifying how payments are taxed.
Termination details: Including reasons for employment cessation and final pay amounts.
These changes aim to improve data accuracy and reduce duplication by sharing payroll information with other government agencies such as Services Australia.
Why Compliance Matters in 2025
By 2025, the transitional grace periods for STP Phase 2 have ended. Employers are now expected to fully comply with these requirements. The ATO has shifted its focus from education to enforcement, meaning businesses that fail to meet their obligations could face significant penalties. Compliance is no longer optional—it is essential for avoiding fines and maintaining smooth business operations.

Consequences of Non-Compliance with STP Reporting
Non-compliance with STP Phase 2 can result in various penalties and complications for businesses.
Financial Penalties
The ATO imposes fines for late or incorrect STP reports based on the size of the business:
Small businesses (19 or fewer employees): Up to $1,050 per missed report.
Medium businesses: Up to $2,100 per missed report.
Large entities: Up to $5,250 per missed report.
Significant global entities: Penalties can reach $525,000.
These fines accumulate quickly if multiple pay runs are affected.
Increased Scrutiny from the ATO
Repeated errors or omissions in STP reports may trigger broader audits of your business’s tax affairs. This could lead to additional investigations into PAYG withholding, super contributions, or other payroll-related obligations.
Operational Disruptions
Failing to comply can disrupt your ability to process payroll efficiently. Errors in STP data may delay tax returns for employees or create complications when interacting with government agencies like Services Australia.
Common Challenges Businesses Face with STP Compliance
Even well-intentioned employers can encounter challenges when meeting their STP obligations. Recognising these common issues is the first step toward addressing them effectively.
Outdated Payroll Software
Some businesses rely on accounting software that is not fully updated or certified for STP Phase 2. Without an STP-enabled payroll system, generating accurate reports becomes nearly impossible.
Data Accuracy Issues
Errors in employee information—such as incorrect tax file numbers or misclassified income types—are among the most frequent causes of non-compliance. These mistakes can occur during data entry or when transitioning between payroll systems.
Lack of Staff Training
Payroll staff may not fully understand the expanded requirements of STP Phase 2. This knowledge gap can lead to incomplete or incorrect reporting.
Complex Employment Arrangements
Businesses with diverse employment types (e.g., casual workers, family members on payroll) often struggle with categorising payments correctly under the new rules.
Practical Steps to Avoid Penalties in 2025
Staying compliant with Single Touch Payroll reporting requires a proactive approach. Here are actionable steps businesses can take to avoid penalties:
Step 1: Upgrade Your Payroll Software
Ensure your accounting software is certified for STP Phase 2 reporting. Look for features such as:
Automatic updates aligned with ATO requirements.
Pre-submission validation checks to identify errors before reports are sent.
Integration capabilities for seamless data sharing across systems.
If you’re unsure whether your current system meets these standards, consult your software provider or a registered tax agent.
Step 2: Conduct Regular Data Audits
Regularly review your payroll data to ensure accuracy:
Verify employee details such as tax file numbers and employment types.
Check that all payments are correctly classified (e.g., separating wages from allowances).
Reconcile your payroll reports against financial year records to catch discrepancies early.
Step 3: Train Your Payroll Team
Invest in ongoing training for your payroll staff:
Educate them on the specific requirements of STP Phase 2.
Provide clear guidelines on how to process payroll accurately.
Encourage them to stay informed about updates from the ATO and other government agencies.
Step 4: Establish Error Correction Procedures
Mistakes happen—but addressing them promptly can prevent penalties:
Monitor ATO notifications for rejected reports or flagged issues.
Implement a clear process for correcting errors within the ATO’s recommended timeframe (usually 14 days).
Keep detailed records of all corrections made.
Step 5: Seek Professional Support
If compliance feels overwhelming, consider partnering with experts:
Registered tax agents can help you navigate complex requirements and resolve issues efficiently.
Outsourcing payroll processing may be a cost-effective solution for small businesses lacking internal resources.
What To Do If You’re Already Non-Compliant
If you’ve fallen behind on your reporting obligations, it’s essential to act quickly:
Contact the ATO: Inform them of your situation and request guidance on rectifying errors.
Rectify Past Reports: Submit corrected reports as soon as possible using your accounting software.
Develop a Compliance Plan: Work with a professional advisor to implement systems that prevent future issues.
The ATO often takes a lenient approach toward businesses that demonstrate genuine efforts to comply. Proactive communication and timely action can help minimise penalties.
