(a) There shall be exempted from the sales and use tax imposed by this chapter any sales of interstate telecommunication and international telecommunication services to a business for use in the operation of one (1) or more call centers. “Call center” means a single location that utilizes telecommunication services in one (1) or more of the following activities: customer services, soliciting sales, reactivating dormant accounts, conducting surveys or research, fund raising, collection of receivables, receiving reservations, receiving orders, or taking orders. A call center shall have at least two hundred fifty (250) employee jobs engaged primarily in such call center activities.

(b) No dealer shall sell any such interstate telecommunication and international telecommunication service under the claim that the service is exempt from the sales or use tax levied by this chapter, where the exemption from taxation is claimed because the vendee or user is entitled to an exemption as a call center, unless the vendee or user shall have issued to it by the commissioner an exemption certificate declaring that such call center is entitled to the exemption. In the event a business operating a call center uses its exemption authorization to purchase other services not exempted, the business shall be liable for applicable tax, penalty, and interest. The dealer shall maintain a copy of such exemption in the dealer's records to document that the purchaser was entitled to the exemption.
