The Illinois Prevailing Wage Act (IPWA) is a union-driven statute that imposes significant compliance responsibilities on construction contractors, developers, property owners, and public entities throughout the state. The law is notoriously complex, frequently amended, and strictly enforced by the Illinois Department of Labor (IL DOL).
Core Compliance Duties for Contractors
Contractors performing qualifying work on projects covered by the IPWA must meet several key requirements:
- Pay laborers the prevailing wage (base hourly pay plus applicable fringe benefits);
- Display prevailing wage rates at the job site;
- Notify subcontractors and lower-tier contractors in writing of prevailing wage requirements;
- Keep and preserve detailed payroll and timekeeping records; and
- Submit certified payrolls to the IL DOL through its online portal.
Required Payroll Records
Contractors must carefully maintain documentation for every worker employed on a prevailing wage job. These records must include:
- Name, address, and, if available, phone number;
- Last four digits of the Social Security number;
- Gender, race, ethnicity, and veteran status;
- Job classification(s) and skill level (e.g., apprentice, journeyman);
- Gross and net wages per pay period;
- Hours worked each day, along with start and end times;
- Hourly base and overtime pay rates;
- Hourly fringe benefit rate;
- Name and address of fringe benefit funds, and if applicable, the plan sponsor and administrator.
Each month, contractors must upload a certified payroll report covering the prior month’s work. The report should include all of the above data—except daily start and end times, which may be omitted.
Certification Requirements
Certified payrolls must be accompanied by a declaration, signed by an employer representative, attesting that:
- The submitted records have been reviewed and are accurate;
- All workers were paid no less than the required prevailing wage rate; and
- The signer understands that knowingly submitting false records is a Class A misdemeanor.
Major Changes Effective June 30, 2025
Under SB1344, beginning June 30, 2025, new civil penalties apply for failing to submit certified payrolls on time. Specifically:
- A first violation can trigger a fine of up to $1,000.
- A second (or subsequent) violation within five years may incur a penalty of up to $2,000.
- A repeat violation occurring after five years is treated as a first offense.
- Each month that a certified payroll is not submitted counts as a separate violation.
Violations can be contested by requesting an administrative hearing within 10 business days of receiving notice. However, if the contractor missed the filing deadline, the IL DOL is presumed to have acted with “good cause.” Simply claiming ignorance of the rules won’t suffice.
Beyond the fines, repeated noncompliance can carry more severe consequences. Two separate violations within five years can lead to DEBARMENT from performing work on Illinois prevailing wage projects for up to four years.
Bottom Line
The IPWA remains a high-stakes, high-risk law for those in the construction industry. With each revision, the law becomes more burdensome and difficult to navigate. Contractors, developers, and public entities must stay vigilant and thoroughly understand both the substantive and procedural requirements—or risk costly penalties and prolonged exclusion from public work opportunities.
