Chicago, Illinois employers must follow a mix of city ordinances, state rules, and federal requirements when running payroll.

Use this guide to confirm licensing, withholdings, paid sick leave and minimum wage compliance, recordkeeping periods, reporting deadlines, and where to get official forms or file complaints.

Payroll compliance checklist

• Register your business and obtain required Chicago business licenses; confirm license type on the City of Chicago licensing page^[2].
• Set up employer withholding registrations with the Illinois Department of Revenue for state income tax withholding^[3].
• Obtain a federal Employer Identification Number (EIN) from the IRS and determine federal deposit schedule.
• Confirm compliance with Chicago minimum wage and paid sick leave ordinances and post required notices for employees^[1].
• Establish pay periods and payroll tax deposit/calendar controls to meet federal, state, and local deadlines.
• Maintain payroll records (hours, wage rates, deductions, tax forms) for the period required by applicable law.
• Implement an internal review and an annual external payroll audit or tax filing review.

Penalties & Enforcement

Enforcement for payroll-related city ordinances in Chicago is primarily handled by the Department of Business Affairs and Consumer Protection (BACP) and other designated city offices; state and federal agencies may enforce their own withholding and tax rules. Exact fine amounts and schedules are sometimes set in ordinance text or administrative rules; if a fine or range is not shown on the cited official page, this text states that fact and cites the page.

• Monetary fines: specific dollar amounts for city ordinance violations are not specified on the cited page when the ordinance summary or enforcement page does not list amounts; see official ordinance or enforcement notice for amounts^[1].
• Escalation: many enforcement paths allow initial warnings, civil fines, and increased penalties for repeat or continuing offences; exact escalation ranges are not specified on the cited summary page^[1].
• Non-monetary sanctions: orders to pay back wages, administrative orders, license suspension or revocation, permit conditions, and referral for civil litigation or criminal prosecution are possible under city enforcement regimes^[1].
• Enforcer and complaints: BACP handles many workplace and licensing complaints; employees and employers may file complaints through BACP’s complaint portal or contact pages^[2].
• Appeals: administrative appeal routes and timelines depend on the specific ordinance or licensing code; the cited city pages describe complaint submission and review processes but may list specific appeal time limits only within full ordinance text or formal orders^[2].
