Relief for Filers of Form ST-556 and ST-556-LSE on Computerized Vehicle Registration Outage

To: All retailers filing Forms ST-556, Sales Tax Transaction Return, and ST-556-LSE, Transaction Return for Leases

The Illinois Department of Revenue (IDOR) is granting relief for taxpayers impacted by the outage of CDK Global’s Computerized Vehicle Registration (CVR) system for filing Forms ST-556, Sales Tax Transaction Return, and ST-556-LSE, Transaction Return for Leases.

What relief is being granted?

IDOR is waiving penalties and interest for late filing and late payment of tax and ensuring that affected taxpayers can claim the retailer’s allowance for timely filing and payment.

Who can claim this relief?

This relief is for taxpayers who normally use the CVR system to file Forms ST-556 or ST-556-LSE and is allowed for returns due June 19, 2024, up to and including July 16, 2024.

How does an affected taxpayer claim this relief?

To be granted relief, all returns impacted by the CVR system outage must be filed electronically or postmarked no later than August 5, 2024. Any taxpayer filing a paper Form ST-556 or ST-556 LSE must clearly write “CVR OUTAGE” at the top of the paper return to indicate that the taxpayer is requesting relief. An affected taxpayer also may request to have IDOR review the taxpayer’s account for impacts related to the outage to determine the taxpayer’s eligibility for relief.

Requests may be sent by calling 217 785-6606 or emailing REV.salestaxcorrespondence@illinois.gov.
