Instructions
This exemption certificate is to be completed by the purchaser claiming exemption from tax and given
to the seller. The seller must retain this certificate as proof that exemption has been properly claimed.
The certificate must be complete to be accepted by the seller. The seller can accept an exemption
certificate only on property that is qualified (see the exemptions below) or based on the nature of the
buyer. If property or services purchased for resale or processing are used or disposed of by the
purchaser in a nonexempt manner, the purchaser is then responsible for the tax.
