Indiana Code Title 6. Taxation § 6-1.1-10-2

Sec. 2. (a) Except as otherwise provided by law, the property owned by this state, a state agency, or the bureau of motor vehicles commission is exempt from property taxation.

(b) Real property leased to a state agency is exempt from property taxes if the lease, regardless of the commencement date, requires the state agency to reimburse the owner for property taxes.  If a state agency leases less than all of a parcel of real property, the exemption provided by this subsection is a partial exemption that is equal to the part of the gross assessed value of the real property attributable to the part of the real property leased by the state agency.
