The University of Massachusetts Lowell is exempt from paying Massachusetts state sales tax. The tax-exempt number appears on the front of each ProCard. This number must be given to all vendors by the cardholder at the time of the transaction to exempt payment of state sales tax. It is the cardholder's responsibility as an agent of the university to ensure proper use of the university's tax-exempt number.
If sales tax is billed incorrectly to the cardholder's account, it is the responsibility of the cardholder to dispute the charge with the vendor.
