Ind. Code § 6-6-1.1-801
Until a distributor pays the license tax on gasoline he receives, the tax money he collects on the sale of gasoline is state money. A distributor who collects such license tax money shall hold it in trust for the state and for payment to the department as provided in this chapter. In the case of a corporate or partnership distributor, every officer, employee, or member of the employer who in that capacity is under a duty to collect the tax, is personally liable for the tax, penalty, and interest. Taxes collected on gasoline, except those collected at a taxable marine facility, shall be used only for highway purposes and for payment of any part of the cost of traffic policing and traffic safety incurred by the state or any of its political subdivisions, as may be authorized by law.
