ILLINOIS SALE TAX

You will be charged sales tax unless proper documentation is filed with our Business Office. For purchases for resale, we must have a copy of your current Certificate of Resale on file. For exempt organization, we must have a copy of the state issued letter with your tax exemption # (E...) on file. Companies working on tax exempt projects must provide an exemption letter or form for each tax exempt project. Please inform us of your tax exempt status when you place your order.
