We do work with many sales tax exempt and reseller organizations. Midwest Salt is required by the Illinois Department of Revenue to maintain records proving its non-sales tax customers are exempt or reselling the goods. If you meet the requirements as a sales tax exempt organization fax us your exempt certificate. If you are a reseller of goods then complete, sign, and fax us form IL-CRT-61, Certificate of Resale. Upon receipt of either form we will remove the sales tax from your order. Please contact us if you have any questions.
