| Ban-the-Box scope | Statewide (Job Opportunities for Qualified Applicants Act) |
| Salary history | Banned (820 ILCS 112) |
| Cannabis testing | CRTA off-duty protection |
Lookback period
Illinois follows the FCRA window. Sealed and expunged records under 20 ILCS 2630/5.2 must be suppressed.
Ban-the-Box and Fair Chance rules
Employers with 15+ workers may not inquire about criminal history until after the candidate is selected for an interview or, where no interview occurs, until after a conditional offer.
Salary history
The Equal Pay Act bars salary-history inquiries and, as of 2025, requires pay scale and benefits in job postings for employers with 15+ workers.
Cannabis & drug testing
The Cannabis Regulation and Tax Act (820 ILCS 55) protects off-duty use; impairment must be demonstrated by articulable symptoms.

Frequently asked questions about Illinois background checks
How long does a background check take in Illinois?
Most SafestHires Illinois background checks complete in under 24 hours when the county courts of record are electronic. Manual-access counties in Illinois typically add 1–3 business days, and verification-heavy packages (employment, education, professional license) usually land in 1–3 business days end-to-end. See the state-by-state turnaround guide for county-level detail.
What shows up on a Illinois employment background check?
A standard Illinois employment background check returns an SSN trace and address history, national criminal database scan, sex offender registry, county criminal records for every Illinois county lived or worked in during the FCRA lookback window, federal criminal records, and OFAC/global sanctions. Common IL add-ons include employment and education verification, professional license verification, motor vehicle records, and drug screening.
How much does a Illinois background check cost?
SafestHires prices Illinois background checks per component — no platform fees, no seat licenses, no minimums. A standard county criminal + national database + SSN trace package for Illinois typically falls in the $20–$45 range depending on how many IL counties are searched and which add-ons are included. Use the pricing calculator for a IL-specific quote.
Do I need consent to run a background check on a Illinois candidate?
Yes. Federal FCRA §1681b(b)(2) requires a stand-alone written disclosure and the candidate's written authorization before any consumer report is procured, and Illinois follows that federal baseline. Additional IL-specific disclosures may apply — SafestHires builds the correct Illinois disclosure package into every order automatically. See the sample forms library for templates.
Can Illinois employers run a Financial Risk Search?
Yes. The SafestHires Financial Risk Search (bankruptcies, civil judgments, and tax liens from public records) is available for Illinois hires in fiduciary, finance, cash-handling, and other roles with a documented permissible-purpose need. It is a public-record search — scoped and adverse-actioned like any other component under FCRA §§615 and 604.
How far back can a Illinois employer look at criminal records?
Illinois follows the FCRA window. Sealed and expunged records under 20 ILCS 2630/5.2 must be suppressed.
