Common Payroll Mistakes Leading to Underpayments

Ensuring wage compliance is crucial for businesses to avoid costly errors, legal penalties, and reputational damage. Unfortunately, payroll mistakes are common, often resulting in employee underpayments. These errors can lead to legal disputes and even allegations of wage theft. Regular wage audits and payroll audits help businesses stay compliant and prevent financial liabilities.
Below are the most common payroll mistakes that can lead to underpayments and how to avoid them.
1. Incorrect Employee Classification
One of the biggest payroll errors occurs when businesses misclassify workers. Incorrectly classifying employees as independent contractors or casual workers instead of full-time or part-time staff can lead to underpayments due to missed entitlements such as annual leave, sick pay, and superannuation. Conducting legal audits ensures proper employee classification and compliance with labour laws.
2. Miscalculating Overtime and Penalty Rates
Failing to pay correct overtime rates or penalty rates is a common cause of wage theft. Many awards and agreements have specific rules for overtime and weekend work. Employers must ensure payroll systems are updated to reflect these rates correctly. Running routine payroll audits can help identify discrepancies and ensure employees receive the correct compensation.
3. Ignoring Changes in Wage Laws
Minimum wage rates and award conditions frequently change. Businesses that do not keep up with these updates risk underpaying employees. Employers should stay informed about Fair Work regulations and conduct wage audits regularly to ensure ongoing wage compliance.
4. Payroll System Errors
Automated payroll systems help streamline processing but can also lead to errors if not configured correctly. Common issues include incorrect tax calculations, missing pay items, or failing to account for changes in employee working hours. To prevent errors, businesses should review their payroll system settings and schedule payroll audits to verify calculations.
5. Failing to Track Hours Accurately
Errors in timekeeping often result in underpayments. If businesses rely on manual timesheets or outdated tracking systems, they risk underreporting employee hours. Investing in a reliable time-tracking system and verifying records during wage audits ensures accuracy and prevents wage disputes.
6. Deducting Wages Incorrectly
Employers must be cautious when making deductions from employee wages. Unauthorized or incorrect deductions—such as for uniforms, meals, or equipment—can violate wage compliance laws. Before deducting wages, businesses should review employment contracts and industry standards. Legal audits can help identify improper deductions and prevent disputes.
7. Missing Superannuation Payments
Failing to pay the correct superannuation contributions is a frequent payroll mistake. Employers must ensure super is paid on time and at the correct rate. Conducting regular payroll audits can help detect and rectify missing or incorrect super payments before they become a compliance issue.
How to Complete a Wage Audit and Avoid Underpayments
To ensure wage compliance, businesses should conduct wage audits by:
- Reviewing payroll records, including timesheets and payslips.
- Verifying employee classifications and ensuring correct entitlements.
- Checking compliance with award wages, overtime, and penalty rates.
- Running payroll reports to identify discrepancies.
- Rectifying any underpayments immediately and keeping detailed records.
By prioritising payroll audits, legal audits, and wage audits, businesses can avoid wage theft, maintain compliance, and build trust with employees.
