The Mauryan administration had a hierarchical structure for revenue collection. The Samharta was the chief revenue collector at the central level. Pradesika were high-ranking officers, often heading large administrative divisions and supervising revenue collection within their charge. Rajukas were initially responsible for revenue collection and surveying land, later acquiring judicial powers, operating at a level below Pradesikas. Sthanikas were district-level officers responsible for revenue collection within their respective districts, reporting to the Pradesika or Rajuka. Thus, the ascending order of rank from lowest to highest is Sthanika, Rajuka, Pradesika, and Samharta.
