The Samharta was the chief revenue collector and was responsible for the income and expenditure of the state treasury. This position was crucial for the administration of the vast Mauryan Empire, making the Samharta one of the highest-ranking administrative officers dealing with state finance. Rajukas were important officers, especially in administering justice and dispensing rewards and punishments in districts, but the Samharta's role in central finance administration was arguably more encompassing at a higher level. Amatyas was a general term for officials or ministers.
