In Illinois, almost every company that regularly collects consumer debts owned by someone else must hold a license issued by the Illinois Department of Financial and Professional Regulation (IDFPR) under the Illinois Collection Agency Act (225 ILCS 425). Collecting a consumer debt in Illinois without that license is not just a rule violation, it is a crime, and a collector that is not properly licensed generally has no right to pursue you at all. That licensing requirement, which the federal Fair Debt Collection Practices Act (FDCPA) does not impose, is one of the most powerful and least-known protections Illinois gives consumers.
The Illinois Collection Agency Act: licensing comes first
The federal FDCPA sets a national floor: it bars harassment, false statements, and unfair practices by third-party collectors. Illinois builds a second, higher wall on top of it. The Illinois Collection Agency Act requires collection agencies, debt buyers, and most collection law firms acting as agencies to be licensed by IDFPR before they can demand payment from an Illinois resident. The Act also defines a long list of prohibited practices that closely track, and in places exceed, the FDCPA.
Why does the license matter to you? Because if a collector is unlicensed, you can challenge its standing to collect or sue. You can also report the unlicensed activity to IDFPR, which has authority to investigate, fine, and shut down violators. You can verify whether an agency holds a current Illinois license through IDFPR's online license lookup before you pay a dollar.
Protections that go beyond the FDCPA
Illinois layers several consumer protections on top of the federal baseline:
Broader conduct rules. The Collection Agency Act prohibits threats, deception, harassment, and unfair collection tactics. Many of these mirror the FDCPA, but they apply through a state agency that can pull a collector's license, giving Illinois consumers a second enforcement path even when a federal claim is hard to bring.
The Consumer Fraud and Deceptive Business Practices Act. Illinois's broad consumer-fraud statute (815 ILCS 505) reaches deceptive and unfair collection conduct and lets the Attorney General, and in many cases private consumers, seek damages, including the possibility of attorney's fees. This statute can apply even to original creditors that the FDCPA usually does not cover.
A tighter wage-garnishment cap. This is one of the clearest places Illinois beats federal law. Federal law (the Consumer Credit Protection Act) generally lets creditors garnish up to 25% of disposable earnings. Illinois law (735 ILCS 5/12-803) limits a wage deduction to the lesser of 15% of gross weekly wages, or the amount by which disposable earnings exceed 45 times the Illinois (or federal, whichever is higher) hourly minimum wage. In practice that 15% ceiling protects far more of your paycheck than the federal 25% rule.
Protected income and exemptions. Illinois shields certain funds from collection, and federal benefits such as Social Security generally remain exempt. Illinois also provides personal-property and wildcard exemptions that protect a portion of your assets from a judgment.
How long can an Illinois debt be sued on?
The statute of limitations controls how long a creditor or debt buyer has to file a lawsuit. In Illinois the clock generally runs 10 years for written contracts (735 ILCS 5/13-206) and 5 years for oral or unwritten contracts (735 ILCS 5/13-205). Many credit-card collection cases are treated under these provisions, though the exact category can be disputed. Once the limitations period has run, the debt is "time-barred" and a collector cannot win a lawsuit on it, though under the FDCPA a collector may still ask you to pay voluntarily. Be careful: making a payment or even acknowledging the debt in writing can sometimes restart the clock, so get advice before you respond to an old account.
The minimum wage that drives your garnishment math
Because Illinois ties the garnishment exemption to the state minimum wage, the protected floor rises as the wage rises. As of 2026 the Illinois minimum wage is $15.00 per hour for most employees statewide, following the schedule that brought it to $15.00 on January 1, 2025. Some municipalities, such as Chicago and parts of Cook County, set higher local minimums. Because these figures can change and local rates vary, confirm the current minimum wage with the Illinois Department of Labor before relying on a specific garnishment calculation.
How to enforce your rights and file a complaint
If a collector harasses you, lies about a debt, tries to collect more than Illinois allows, or appears to be unlicensed, you have several options:
Demand verification in writing. Under the FDCPA you can dispute a debt and request validation, generally within 30 days of the collector's first written notice. Send your request by a method you can document.
File with the Illinois Attorney General. The Office of the Illinois Attorney General runs a Consumer Protection Division (its Consumer Fraud Bureau) that accepts complaints about abusive debt collection and deceptive practices. You can file online or by mail; the office can mediate disputes and, in appropriate cases, pursue enforcement under the Consumer Fraud Act.
Report licensing problems to IDFPR. Complaints about an unlicensed agency, or about misconduct by a licensed one, go to the Illinois Department of Financial and Professional Regulation, which oversees the Collection Agency Act.
Use the federal regulators too. You can also complain to the Consumer Financial Protection Bureau and report FDCPA violations, and you may have a private right of action for damages.
Where to verify the law
Statutes and dollar figures change, and individual cases turn on their facts. Confirm the licensing status of any collector through IDFPR, verify current minimum-wage and garnishment figures with the Illinois Department of Labor, and review collection-complaint procedures through the Office of the Illinois Attorney General's consumer-protection pages. For a disputed lawsuit, a time-barred debt, or a garnishment you believe is too high, consult an Illinois consumer attorney or a legal-aid organization before acting.

Frequently asked questions
Do debt collectors have to be licensed in Illinois?
Yes. Under the Illinois Collection Agency Act (225 ILCS 425), most agencies and debt buyers collecting consumer debts in Illinois must be licensed by the Illinois Department of Financial and Professional Regulation (IDFPR). Collecting without a required license is unlawful, and you can verify a collector's license through IDFPR's online lookup and report unlicensed activity.
How much of my wages can be garnished in Illinois?
Illinois caps wage garnishment at the lesser of 15% of your gross weekly wages or the amount your disposable earnings exceed 45 times the minimum wage (735 ILCS 5/12-803). That 15% limit is more protective than the federal cap of up to 25% of disposable earnings.
How long can a creditor sue me for a debt in Illinois?
Generally 10 years for written contracts (735 ILCS 5/13-206) and 5 years for oral or unwritten contracts (735 ILCS 5/13-205). After the period runs, the debt is time-barred and cannot be enforced in court, but making a payment or written acknowledgment can sometimes restart the clock, so seek advice first.
How do I file a debt collection complaint in Illinois?
File with the Office of the Illinois Attorney General's Consumer Protection Division (Consumer Fraud Bureau), online or by mail. For licensing problems, complain to IDFPR. You can also report FDCPA violations to the federal Consumer Financial Protection Bureau.
Does Illinois protect me more than the federal FDCPA?
Yes. On top of the FDCPA's national floor, Illinois requires collector licensing, applies the Consumer Fraud and Deceptive Business Practices Act, and imposes a tighter 15% wage-garnishment cap. These give Illinois consumers extra state enforcement paths beyond federal law.
