USA State Payroll Rates + Resources: State of Illinois: Unemployment Insurance Reporting & Payments


The purpose of this documentation is to outline the processes and requirements associated with Unemployment Insurance Reporting & Payments to the proper authorities in the state of Illinois.

Unemployment Insurance Reporting & Payments

The Rules of the Illinois Department of Employment Security (56 Ill. Code 2760.140) require that employers with 25 or more employees during the prior calendar year file their Quarterly Employer’s Contribution and Wage Report (UI 3/40) electronically on the MyTax Illinois website.

Employers with fewer than 25 employees, can use the UI 3/40 Employer's Contribution and Wage Reporting form. 

Whether you have fewer than 25 employees or more than 25 employees, filing due dates for the UI 3/40 electronic and paper forms are:

QuarterMonths In QuarterDue Date
1st QuarterJanuary - MarchApril 30th

4th QuarterOctober - DecemberJanuary 31st

Also, Pursuant to Public Act 97-0689, employers with a cumulative total of 25 or more employees in the prior calendar year are required to submit monthly wage reports electronically.

Employers will continue to submit quarterly contribution and wage reports as outlined in the above schedule, but you will also submit eight additional MONTHLY wage reports per year as outlined in the below schedule.

  • Monthly Reports are filed electronically through MyTax Illinois only, the Department's online tax filing/wage reporting application. 

  • Monthly Reports are required for the first and second months of each quarter: January and February; April and May; July and August; October and November.

  • Please Note: There is NOT a manual entry option for the monthly wage reports.

  • Your monthly wage reports should contain only employee names, social security numbers, and each employee’s total wages for the period being reported.

  • Unemployment insurance contributions are not calculated or remitted.

  • Failure to submit in an electronic format through MyTax Illinois will result in a penalty.
