Sales tax exemption certificates (Michigan and Indiana institutions)

MCLS is required to have a tax exemption certificate on file for each tax-exempt institution purchasing taxable products (bibliotheca products for example). If no form is on file, MCLS must add sales tax to your order at time of invoicing. If your institution is exempt, please complete the appropriate tax exemption form (linked below), print, and fax the form to MCLS at 269-210-7250.
