Illinois TaxNet

 
 
Illinois TaxNet is a program for Illinois businesses to electronically file and pay your unemployment Insurance Tax and Wage Reports (UI-3/40), and make your IL-501 payments by direct debit via a bank account registered with Illinois TaxNet. Visit Illinois Department of Employment Security to register and obtain digital certification.

Note: The Illinois Withholding Income Tax Return (Form IL-941) can no longer be filed using TaxNet.  Please use the department’s MyTax Illinois program to file this return.
