Ind. Code § 20-42-1-8

Sec. 8. The payment of annual interest must be full and complete every year. The payment must appear in the county auditor's report to the state superintendent. The state superintendent shall, at any time when the state superintendent discovers from the report, or otherwise, that there is a deficit in the amount collected, for want of prompt collection or otherwise, direct the attention of the board of county commissioners and the county auditor to the fact. The board of commissioners shall provide for the deficit in their respective counties.
