Why are Certified Payroll Audits Conducted?
Certified payroll audits are conducted by the Department of Labor (DOL) to verify compliance with the Davis-Bacon and Related Acts. These laws require contractors to pay workers the prevailing wage rate for their specific job classification. The DOL examines payroll records to confirm accurate reporting of hours worked, wages paid, and fringe benefits provided.

What to Expect During Certified Payroll Audits
A certified payroll audit can be a stressful experience. The DOL requests various documents, including payroll records, timecards, employee classification documents, and project-specific information. Auditors interview employees and supervisors to verify payroll data accuracy.
The audit process can take several weeks or months. The DOL thoroughly reviews your records, potentially requesting additional documentation or clarification. If discrepancies arise, you’ll have an opportunity to explain your position.
Potential Findings of Certified Payroll Audits
Common audit findings include:
- Incorrect Wage Rates: Determining the correct wage rate is complex due to factors like location, job classification, and fringe benefits. Applying the wrong wage rate to an employee is a common mistake. For example, paying a laborer a carpenter’s rate.
- Fringe Benefit Calculations: Fringe benefits, such as health insurance, pension contributions, and vacation pay, can be challenging to calculate accurately. Errors in determining their value or applying them correctly can lead to audit findings.
- Employee Misclassification: Distinguishing between employees and independent contractors is crucial. Misclassifying employees as independent contractors to avoid payroll taxes and benefits is a common violation. Understand IRS and Department of Labor guidelines for worker classification.
- Overtime Pay Errors: Calculating overtime pay correctly can be complex, especially for employees with varying work schedules. Mistakes in determining the regular rate of pay or calculating overtime hours can result in audit findings.
- Kickbacks: Employees being required to return a portion of their wages to the employer is illegal and can lead to severe penalties.
- Withholding of wages: Failing to pay employees for all hours worked or for accrued benefits is a serious violation of labor laws.
Penalties for Violations of Certified Payroll Audits
Penalties for certified payroll violations can be very severe. The DOL can assess back wages, liquidated damages, and give civil penalties. Additionally, the DOL may debar your company from bidding on future federal contracts. In severe cases, criminal charges can be brought against individuals responsible for the violations.
How to Prepare for Certified Payroll Audits
Maintaining accurate and complete payroll records is crucial for preparing for a certified payroll audit. This involves:
- Accurate timekeeping: Ensure all employees accurately record their hours worked, including start and stop times, meal breaks, and overtime.
- Proper employee classification: Classify employees correctly as hourly, salaried, or exempt, following federal and state labor laws.
- Accurate wage calculations: Calculate wages and overtime pay correctly, considering all applicable wage rates and premium pay requirements.
- Complete payroll records: Maintain detailed payroll records, including timecards, pay stubs, pay registers, and employee classification documents.
- Regular reviews: Conduct regular internal audits of your payroll records to identify and correct potential problems.
Additional Tips for Preparing for Certified Payroll Audits
- Train your employees: Educate employees about the importance of accurate timekeeping and potential payroll error consequences.
- Document your wage determination process: Keep detailed records of how you determine prevailing wage rates, including sources and calculations.
- Maintain good communication with subcontractors: Ensure subcontractors comply with certified payroll requirements and provide necessary documentation.
- Consider payroll software: Invest in payroll software to maintain accurate records, generate compliant reports, and assist with audit preparation.
Common Audit Mistakes
Understanding common audit mistakes helps proactively address potential issues. Frequent errors include:
- Timecard discrepancies: Inaccurate or incomplete timecards are a major red flag. Ensure timecards are clear, accurate, and include necessary job information.
- Missing or incomplete payroll records: The absence of essential documents can hinder the audit process. Maintain complete payroll records.
- Subcontractor issues: Ensure subcontractors understand certified payroll requirements and provide necessary documentation.
- Math errors: Double-check wage rates, overtime calculations, and fringe benefit contributions for accuracy.
- Record retention: Retain payroll records for the required period to avoid penalties.

The Importance of Recordkeeping
Meticulous recordkeeping is essential for a smooth audit. Document everything, including:
- Timecards with detailed job information and hours worked
- Payroll registers with employee names, rates, deductions, and fringe benefits
