Sales tax must be paid to a vendor when an employee makes a purchase with personal funds or a personal credit card. Since CWM is a tax-exempt organization, sales tax is not paid to a vendor when an employee uses a CWM Purchasing Card. It is recommended that CWM Purchasing Cards be used whenever possible to take advantage of our tax-exempt status. Reimbursement to employees for purchases made with personal funds or a personal credit card should only occur for emergency situations or for situations where the use of a CWM Purchasing Card is prohibited. In these instances, reimbursement of Sales tax is prohibited.
