Ind. Code § 6-2.5-8-8
(b) The following are the only persons authorized to issue exemption certificates:
(e) 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.
(f) 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:
(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 , unless the department revokes the exemption certificate. 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 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. A power subsidiary or a person selling the services or commodities listed in IC 6-2.5-4-5 shall maintain records sufficient to document each one (1) to one (1) meter change. A person may request the department to reissue an exemption certificate with a new meter number in the event of a one (1) to one (1) meter change. 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 is required to collect the state gross retail tax from the date of the meter change.
