Relief for Eligible Employers from Penalties and Interest in Wage Reporting

To fight theft in and abuse of benefit programs such as Medicaid and unemployment insurance, Illinois lawmakers required certain employers to submit wage reports on a monthly basis. Previously, all employers were required to report wage information quarterly. Electronic and monthly wage reporting have the potential to stop improper payments before they are issued and save Illinois taxpayers hundreds of millions of dollars each year. These savings help reduce unemployment insurance tax rates.

The Department adopted rulemaking, agreed to by the business and labor communities, which required the electronic submission of monthly wage reports from employers of 25 or more in 2013 and phased in the Medicaid reform legislation’s monthly reporting requirement through July 2014.

Though the Department had informed employers through direct mail, email, media reports and through trade groups of this rule change, some employers genuinely misunderstood the implementation schedule for the new electronic reporting requirement and assumed it was the same as the schedule for monthly reporting. Additionally, some employers experienced problems transitioning to monthly reporting, despite their good faith efforts, and many incurred penalties and associated interest charges as a result.

To address this issue, the Department has implemented new rules to help employers with wage report submissions:
These rules:

  • Remove penalties and interest employers incurred as a result of confusion over the new electronic reporting requirement’s implementation schedule. The rule retroactively implements requirement on the same schedule as that for the monthly reporting requirement.

  • Waive up to the first two quarters’ worth of penalties, along with any related interest, for late monthly reports, as long as the employer timely submitted quarterly reports.

The Department will automatically remove penalties and interest to the extent the new rules permit. The Department’s IT division is expected to implement the automated system within the next six months. In the interim, some employers will continue to see the penalties and interest on their quarterly Statements of Account. Once the system change is complete, the Department will notify Employers of any penalties and interest that were waived or otherwise removed. If the employer already paid the penalties and interest, the payment can be credited towards future liabilities. If an employer has requested a waiver of a penalty but the new rules do not permit automatic removal of that penalty, the Department will process the waiver request to determine if there is some other basis for a waiver. The employer will have the right to appeal any unfavorable decision.

To expedite the removal of the penalties and interest, employers should use TaxNet. We appreciate your patience and your help in fighting unemployment insurance benefit fraud. For further information please call the Employer Hotline at (800) 247-4984.


The Medicaid Reform "SMART" Act was designed to root out waste, fraud and abuse in the State's Medicaid program.  It requires monthly wage reports from employers who are required to submit their contribution and wage reports electronically.  ​​
