Indiana Code Title 6. Taxation § 6-6-1.1-408

Sec. 408. (a) If the administrator reasonably determines that the amount of the existing bond, letter of credit, or cash deposit is insufficient to insure payment to the state of the tax and any penalty and interest for which the distributor is or may become liable, then the distributor shall upon written demand of the administrator file a new bond or letter of credit, or increase the cash deposit.  The administrator shall give the distributor at least fifteen (15) days to secure the new bond or letter of credit or make the increased cash deposit.

(b) The new bond, letter of credit, or cash deposit must meet the requirements set forth in section 406 of this chapter.

(c) If the new bond, letter of credit, or cash deposit required under this section is unsatisfactory, the administrator shall cancel the distributor's license certificate.
