Ind. Code § 6-2.5-8-8
(b) The following are the only persons authorized to issue exemption certificates:
(d) A seller that accepts an incomplete exemption certificate under subsection (a) is not relieved of the duty to collect gross retail or use tax on the sale unless the seller obtains:
(2) the relevant data to complete the exemption certificate;
within ninety (90) days after the sale.
(e) If a seller has accepted an incomplete exemption certificate under subsection (a) and the department requests that the seller substantiate the exemption, within one hundred twenty (120) days after the department makes the request the seller shall:
(f) A power subsidiary (as defined in IC 6-2.5-4-5 ) or a person selling the services or commodities listed in IC 6-2.5-4-5 (b) who accepts an exemption certificate issued by the department to a person who is exempt from the state gross retail tax under IC 6-2.5-4-5 is relieved from the duty to collect state gross retail or use tax on the sale of the services or commodities listed in IC 6-2.5-4-5 (b) until notified by the department that the exemption certificate has expired or has been revoked. If the department notifies a power subsidiary or a person selling the services or commodities listed in IC 6-2.5-4-5 (b) that a person's exemption certificate has expired or has been revoked, the power subsidiary or person selling the services or commodities listed in IC 6-2.5-4-5 (b) shall begin collecting state gross retail tax on the sale of the services or commodities listed in IC 6-2.5-4-5 (b) to the person whose exemption certificate has expired or been revoked not later than thirty (30) days after the date of the department's notice. An exemption certificate issued by the department to a person who is exempt from the state gross retail tax under IC 6-2.5-4-5 remains valid for that person regardless of any subsequent one (1) for one (1) meter number changes with respect to that person that are required, made, or initiated by a power subsidiary or a person selling the services or commodities listed in IC 6-2.5-4-5 (b). Within thirty (30) days after the final day of each calendar year quarter, a power subsidiary or a person selling the services or commodities listed in IC 6-2.5-4-5 (b) shall report to the department any meter number changes made during the immediately preceding calendar year quarter and distinguish between the one (1) for one (1) meter changes and the one (1) for multiple meter changes made during the calendar year quarter. Except for a person to whom a blanket utility exemption applies, any meter number changes not involving a one (1) to one (1) relationship will no longer be exempt and will require the person to submit a new utility exemption application for the new meters. Until an application for a new meter is approved, the new meter is subject to the state gross retail tax and the power subsidiary or the person selling the services or commodities listed in IC 6-2.5-4-5 (b) is required to collect the state gross retail tax from the date of the meter change.
