TO OUR CUSTOMERS:  In order to comply with the majority of state and local sales tax law requirements it is necessary that we have in our files a properly executed exemption certificate from all of our customers who claim sales tax exemption. If we do not have this certificate, we are obligated to collect the tax for the state in which the property is delivered.
If you are entitled to sales tax exemption, please complete the certificate and send it to us at your earliest convenience. If you purchase tax free for a reason for which this form does not provide, please send us your special certificate or statement.
This form of certificate has been determined to be acceptable to the following states as of January 31, 1997:
Alabama   Maryland   South Carolina
Alaska   Michigan   South Dakota
Arkansas   Minnesota   Texas
District of Columbia   Missouri   Utah
Georgia   Nevada   Vermont
Idaho   New Mexico   Virginia
Illinois   North Dakota   Washington

NOTE: ILLINOIS DOES NOT HAVE AN EXEMPTION ON SALES OF PROPERTY FOR SUBSEQUENT LEASE OR RENTAL.
CAUTION TO SELLER: In order for the certificate to be accepted in good faith by the seller, the seller must exercise care that the property being sold is of a type normally sold wholesale, resold, leased, rented, or utilized as an ingredient or component part of a product manufactured by the buyer in the usual course of his business.  A seller failing to exercise due care could be held liable for the sales tax due in some states or cities.
Misuse of this certificate by the seller, lessor, buyer, lessee, or the representative thereof may be punishable by fine, imprisonment or the loss of right to issue certificates in some states or cities.
