Illinois unemployment fraud has two very different readers: the person who just got a letter or a 1099-G for a claim they never filed, and the claimant who wants to know what the state counts as fraud and what it costs.
This guide covers both — how to report Illinois unemployment fraud, the identity-theft steps, how to get a corrected 1099-G, what counts as claimant fraud, the penalties and disqualification, and when it becomes a criminal case. Verified against Illinois Department of Employment Security (IDES) as of October 2026.

How to Report Illinois Unemployment Fraud
Report it at https://ides.illinois.gov/unemployment/fraud-id-theft/reporting-unemployment-insurance-fraud.html or call 800-814-0513. Reports can be made anonymously; the agency investigates both claimant and employer fraud.
Illinois Unemployment Fraud in Your Name: If Someone Else Filed
- Report the claim to IDES online or call 800-814-0513 and choose the identity-theft option
- Do not activate any debit card or cash any check IDES mails for a claim you did not file
- Tell your employer, even if you think the employer already told IDES
- Check your credit report and place a fraud alert
- File a report with your local police
Getting a Corrected 1099-G
If you got an IDES 1099-G for benefits you never received, IDES asks you to call 800-244-5631 right away so it can shut down the fake claim and deal with the form (ides.illinois.gov/1099G). IDES says fraudulent payments are not reported to the IRS as your income.
The IRS says that if a corrected form does not arrive in time, you should still file and report only the income you actually received.
What Counts as Illinois Unemployment Fraud by a Claimant
Under 820 ILCS 405/901, fraud means knowingly making a false statement, or knowingly hiding an important fact, to get benefits you are not eligible for. This generally includes not reporting earnings while you claim, working while you certify that you are unemployed, giving a false work-search report, or giving a false reason for losing your job.
Illinois Unemployment Fraud Penalties and Disqualification
You must repay all benefits gained through fraud (820 ILCS 405/901). On top of that, a civil penalty equal to 15% of that amount applies (820 ILCS 405/901.1), and IDES has collected it since December 2019. IDES may also take up to 100% of future benefits and other money the state owes you, and unpaid fraud debt stays on your record with no time limit.
Under 820 ILCS 405/901, a first offense brings 6 penalty weeks, plus 2 more weeks for each additional week you were wrongly paid (for example, 10 weeks of fraud means 6 + 9 x 2 = 24 weeks). The total is capped at 26 weeks, and it must be served within 2 years from when the ineligibility began.
You serve those weeks by certifying for weeks in which you would otherwise be eligible.
When Illinois Unemployment Fraud Becomes a Criminal Case
Making a false statement to get benefits is unlawful under 820 ILCS 405/2800. Under the State Benefits Fraud statute (720 ILCS 5/17-6), it is a Class 4 felony, or a Class 3 felony when more than 300 is obtained. IDES also sends unemployment fraud cases to the U.S. Department of Labor Office of Inspector General. Confirm the exact charge that applies with the state agency or an attorney.
Employer-Side Illinois Unemployment Fraud
Under 820 ILCS 405/2800, an employer that knowingly files a false quarterly wage report commits a Class 4 felony if less than 300 in contributions is owed for that quarter, or a Class 3 felony if 300 or more is owed. A worker who is misclassified as an independent contractor can file a complaint through the Illinois Department of Labor’s misclassification portal under the Employee Classification Act.

Honest Mistakes Are Not Illinois Unemployment Fraud
An honest mistake is treated as a non-fraud overpayment. You still repay it, but IDES generally takes only 25% of each future weekly benefit, has 5 years to collect, and adds no fraud penalty or penalty weeks. You may qualify for a waiver of recoupment if you gave no false information and repaying would cause financial hardship.
If you made an error on a weekly claim, contact IDES promptly to correct it.
The 15% fraud penalty applies in addition to repayment and penalty weeks (820 ILCS 405/901.1). Fraud overpayments can be collected with no time limit and through a 100% benefit offset, while non-fraud overpayments are limited to 5 years and a 25% offset. IDES says it will never send a text message asking for your Social Security or driver’s license number.
Related: if the state says you were overpaid on your own claim, that is a different process — see the Illinois overpayment guide for waivers, repayment plans and the appeal deadline.
Illinois — the bottom line
- Report Illinois unemployment fraud the same day you suspect it — an unreported claim in your name becomes an overpayment in your name.
- Illinois unemployment fraud by a claimant means a knowing false statement; an honest mistake corrected promptly is not fraud.
- Penalties for Illinois unemployment fraud stack: repayment, a monetary penalty, penalty weeks, and in large cases a criminal referral.
