Ind. Code § 5-13-9-8
Any investing officer of a political subdivision that makes a deposit in any deposit or other account may be required to pay a service charge to the depository in which the funds are deposited, if the depository requires all customers to pay the charge for providing that service. However, the service charge imposed must be considered in the computation of the interest rate for determining which depositories are entitled to investments as prescribed by sections 4 and 5 of this chapter. If the total service charge cannot be computed before the investment, the investing officer shall estimate the service charge and adjust the interest rate based on this estimate. The service charge may be paid:
If the manner described in subdivision (2) is used to pay the service charge, the political subdivision must report the net interest deposited in the political subdivision's financial records, and the political subdivision is not required to report the amount of the service charge subtracted in the political subdivision's financial records.
