Illinois Employer HR Compliance Guide

Illinois is among the most active states for employment legislation, enacting new obligations nearly every year. The 2026 compliance landscape includes pay transparency enforcement, a new NICU leave law, AI hiring disclosure rules, and Workplace Transparency Act amendments. Employers operating in Chicago face additional layers beyond state law, including stricter paid sick leave rules and a tip credit phase-out.

Key Facts — Illinois

Minimum Wage: $15.00/hour statewide effective January 1, 2023 (held at that rate through 2026). Chicago rises to $16.60/hour with a further adjustment on July 1, 2026. Employers should monitor Chicago and Cook County schedules separately as they exceed the state floor.
Pay Transparency: Illinois requires tiered compliance under the Equal Pay Act (820 ILCS 112/10(b-25)). All employers must provide wage notification at hire and protect wage discussions. Employers with 15+ employees must include pay scale and benefits in job postings and notify employees of internal promotion opportunities within 14 days of external posting. Employers with 100+ Illinois-based employees must also obtain an Equal Pay Registration Certificate; enforcement and penalties are administered by the Illinois Department of Labor.
Paid Family & Medical Leave: No state PFML program. Illinois does not have a state-run paid family and medical leave insurance program. However, the Illinois Paid Leave for All Workers Act requires most employers to provide up to 40 hours of paid leave annually (see leave_laws).

Priority Compliance Actions

1Audit all job postings to include pay scale and benefits information if you have 15 or more employees, and establish a 14-day internal notification process for promotional opportunities.
2Update paid leave policies to ensure compliance with the Illinois Paid Leave for All Workers Act (40 hours annually, any reason), and add NICU leave provisions ahead of the June 1, 2026 effective date.
3Review independent contractor classifications using the applicable ABC or common law test, and audit any non-compete or non-solicitation agreements against Illinois salary thresholds.
4Confirm ban-the-box hiring procedures delay criminal history inquiries until after a conditional offer, and update AI/automated hiring tool disclosures to meet 2026 requirements.
5If operating in Chicago, track compliance with the city's tip credit phase-out schedule and verify paid sick leave policies meet the stricter Chicago Paid Sick Leave Ordinance requirements.

Leave Laws

Federal FMLA applies to employers with 50+ employees. The Illinois Paid Leave for All Workers Act (effective January 1, 2024) requires employers of all sizes to provide up to 40 hours of paid leave per year, usable for any reason, accruing at 1 hour per 40 hours worked. A new NICU leave law takes effect June 1, 2026, granting additional leave for parents of hospitalized newborns. Chicago employers must also comply with stricter city-level paid sick leave ordinances.

Wage & Hour

Illinois follows federal FLSA overtime rules, requiring 1.5x pay for hours over 40 per week; the most common violation is misclassifying employees as exempt based on job title rather than duties. Chicago is phasing out the tip credit under the One Fair Wage Ordinance, requiring employers to track compliance with city-specific tipped wage schedules. Final paychecks are due on the next regular scheduled payday under the Illinois Wage Payment and Collection Act. Pay frequency must be at least semi-monthly for most employees.

Worker Classification

Illinois is an at-will employment state, though exceptions exist for public policy and implied contract. For independent contractor classification, Illinois generally applies a stringent ABC test under the Employee Classification Act for construction and related industries, while other sectors may use common law or economic reality tests. Non-compete agreements are enforceable only for employees earning more than $75,000/year (rising to $80,000 by 2037), and non-solicitation agreements require earnings above $45,000/year; both require adequate consideration and reasonable scope.

Hiring & Onboarding

Illinois has a statewide ban-the-box law (Job Opportunities for Qualified Applicants Act) prohibiting criminal history inquiries until after a conditional offer is made for employers with 15+ employees. Salary history inquiries are banned under the Equal Pay Act. Employers using AI or automated tools in hiring must provide disclosure to applicants, with updated rules effective 2026. New hires must be reported to the Illinois New Hire Reporting Center within 20 days of the hire date.
