In this article, we tried to analyze administrative- Financial barriers of economic rationalization by utilizing the theoretical approach of Max Weber. In this regard, firstly, we analyzed the characteristics of the public finance organization based on the collective commitment (Liturgical) of the villages, ils (tribes) and guilds in the period Qajar. Then we studied components such as the domination of the livelihoods economy; the suppression of individualism and the expansion of the economy and the division of labor; the lack of competitiveness of the economy in the world system; the weak social mobility as the outcomes of the general tax system governing this period. In the end, based on research findings, the concept of Communal Rationalism has been presented as a theoretical modification with the historical particularity of Qajar Iran.
