What is Prevailing Wage in Illinois?
Illinois requires contractors and subcontractors in the construction industry to pay prevailing wages on all public works projects regardless of project cost. Unlike many states, Illinois does not set minimum project thresholds, meaning prevailing wage requirements apply to:
- All state government construction contracts
- All local government construction contracts
- All school district construction contracts
- All public works construction projects of any value
Under this law, construction workers must receive minimum hourly wages plus fringe benefits based on local standards for similar work within each Illinois county as determined by the Illinois Department of Labor (IDOL).

Setting Initial Rates
The Illinois Department of Labor (IDOL) has several crucial responsibilities related to establishing and maintaining prevailing wage rates. These ensure fairness throughout the contracting process.
The IDOL must:
- Determine appropriate prevailing wages, including hourly rates and benefit rates for each county
- Publish these rates annually for use in public works projects
- Update rates by July 15th each year based on June surveys
- Ensure rates reflect current local conditions and wage standards
Rate Calculation Method
The IDOL follows a structured approach to determine fair and accurate compensation rates by county. They establish rates by analyzing:
- Collective bargaining agreements in each locality
- Actual wages paid on similar construction projects in each county
- Various sources of wage information for specific geographic areas
- Survey data collected from ongoing public works projects
Prevailing Wage Requirements
Prevailing wage laws establish minimum compensation standards for workers on public projects. These requirements ensure fair labor practices and create a level playing field for all contractors bidding on government work.
- Contractor
Contractors bear significant responsibility for ensuring project compliance with prevailing wage regulations. These requirements apply throughout the entire project lifecycle:
- Understanding that all public works projects are subject to prevailing wage requirements
- Paying prevailing wages to all covered workers regardless of project size
- Ensuring all subcontractors comply with prevailing wage requirements
- Maintaining detailed payroll records and documentation
- Submitting required certified payroll reports
How to Submit Prevailing Wage Proof
Illinois's prevailing wage law requires contractors and subcontractors to maintain comprehensive records and submit certified payroll documentation for all public works projects.
This documentation process involves comprehensive record-keeping of worker information, ensuring transparency and accountability on federal projects.
Information needed for prevailing wage compliance includes:
- Detailed certified payroll records for each pay period
- Worker classification documentation
- Proof of wage payments meeting or exceeding county rates
- Fringe benefit payment verification
- Overtime calculation documentation
- Project-specific wage determination records
To maintain compliance, contractors need certified payroll records and evidence of proper wage payments throughout the project duration. The WH-347 Form is commonly used for certified payroll reporting.
The Illinois Prevailing Wage Act requires contractors to certify that they:
- Pay prevailing wages to all covered workers
- Maintain accurate payroll records
- Submit required documentation upon request
- Comply with county-specific wage determinations
- Provide proper worker classifications
This documentation must be maintained throughout the project and available for inspection by IDOL representatives.
Enforcement and Penalties Under Illinois Prevailing Wage Law
The Illinois prevailing wage system relies on robust compliance mechanisms and meaningful penalties to ensure all parties adhere to established standards. These measures protect workers' rights, ensuring compliance with wage standards while maintaining the integrity of public projects.
Wage Payment Rules
Prevailing wage laws establish minimum compensation requirements that cannot be circumvented. This ensures workers receive fair pay for their labor on public projects.
The rules surrounding wage payment include:
- Workers must receive county-specific prevailing rates for their job classification
- Rates include both actual wages and fringe benefits
- Rates are updated annually and vary by county
- Employers cannot pay below these rates, even with worker consent
- All public works projects are covered regardless of value
Violation Consequences
Significant operational and financial repercussions await contractors who fail to comply with prevailing wage requirements, potentially jeopardizing their entire business.
Construction businesses are at risk of penalties, including:
- Investigation and enforcement action by IDOL
- Assessment of unpaid wages plus interest
- Civil penalties and administrative fines
- Potential debarment from future public contracts
- Legal action for willful violations
- Joint liability between contractors and subcontractors
Prevailing Wage Whistleblower Protections
Illinois law includes anti-retaliation provisions specifically designed to protect workers who report violations of prevailing wage requirements or certified payroll discrepancies.
Employees are protected from retaliation when reporting prevailing wage violations:
- Protection from termination
- Protection from disciplinary action
- Protection from discrimination
- Protection from threats or harassment
These protections apply specifically to matters involving prevailing wage compliance. They allow workers to safely report underpayment, misclassification or certified payroll record falsification without fear of employer retaliation.
Penalties
The legal framework includes substantial financial penalties and establishes clear liability structures to encourage compliance.
Financial consequences include:
- Back wage payments plus interest charges
- Administrative penalties for violations
- Joint liability between contractors and subcontractors
- Potential criminal charges for intentional violations
- Loss of eligibility for future public contracts
A contractor or subcontractor found to have violated the Act on two occasions in a five-year period may be disbarred from public works projects for four years

Prevailing Wage Exceptions
Illinois's prevailing wage laws apply to virtually all public works construction projects. However, certain specific exemptions exist under limited circumstances.
These exemptions don't release contractors from fair wage obligations. Instead, the exemptions allow them to follow alternative regulatory frameworks that still maintain worker protections and compensation standards.
Projects may be exempt from Illinois prevailing wage requirements if they:
Follow federal Davis-Bacon Act requirements because the job receives federal funding:
- The Davis-Bacon Act establishes its own prevailing wage determination system
- Contractors must still maintain detailed, accurate records for payroll
- Federal wage classifications may differ from state calculations but maintain worker protections
- Compliance with federal standards requires the same rigorous documentation and enforcement
Qualify for specific statutory exemptions such as:
- Certain maintenance work performed by public employees
- Emergency repair work under specific conditions
- Work performed by volunteers in limited circumstances
- Specific projects explicitly exempted by statute
Fall under specialized categories with different requirements:
- Certain renewable energy projects with specific guidelines
- Projects with unique federal or state funding structures
In all cases, contractors remain responsible for understanding which wage standards apply to their projects. When in doubt, following the higher wage standard ensures compliance with all applicable regulations.
