This article deals with the process of decision-making in the sphere of taxation in Argentina between 1920 and 1945, focusing on the possible influence of the economic elites in that process. Given the central role of decisions over taxation in any fiscal policy and the momentous transformations that occurred in the Argentine system during this period, analysis of this subject can provide a better understanding of the political role that economic elites in Argentina played between the first presidency of Hipólito Yrigoyen (1916–22) and the ascent of Juan Domingo Perón to the presidency in 1946. Drawing on three key episodes in Argentina policy-making – the attempt to introduce an income tax in 1923, the response to the Depression in 1931–32, and the crisis of 1942–43, this article suggests that parliamentary institutions had stronger resilience in Argentina than is usually believed, and corporatist arrangements became rooted in Argentina only with difficulties.
