Illinois Sales Tax Exemption Program
This guide explains how CoreSite customers in Chicago can take advantage of a 10.25% Illinois sales tax exemption on IT equipment, software, and deployment costs through a state-supported incentive program. Available to all customers in the CH2 facility, the program supports both new and existing deployments and is renewable in five-year increments through 2040. To qualify, organizations must provide capital investment and employment projections, designate accounting or HR contacts, and complete a participation agreement with CoreSite and ILDCEO. Ongoing compliance requires annual reporting of employee data, wages, and investment levels. The program significantly reduces infrastructure costs while encouraging long-term growth and investment in data center operations.
