Retailers selling to Illinois customers will face new tax obligations starting January 1, 2025. Previously, these retailers were required to collect and remit the Illinois Use Tax on sales made outside of the state but delivered within Illinois. The change means they will now be subject to a destination-based Retailers' Occupation Tax.
For additional details, refer to FY 2025-10, Retailers’ Occupation Tax Guidance for Out-of-State Retailers and Certain Illinois Retailers.
