Abstract(s)
Ao longo do tempo, a carga fiscal tem vindo a ganhar grande peso na vida das empresas portuguesas, tornando-se crucial o estudo da taxa efetiva de imposto (ETR) e dos seus determinantes. A presente dissertação tem, assim, como objetivo analisar os determinantes da ETR em Portugal. Para este propósito, extraiu-se do Sistema de Análise de Balanços Ibéricos (SABI) uma amostra composta por um painel não equilibrado de 352.816 empresas portuguesas e 1.051.947 observações de quatro exercícios económicos (2019 a 2022). Os resultados deste estudo sugerem que as empresas de maior dimensão, mais rentáveis, mais intensivas em capital e em inventário suportam uma menor ETR. Para além da estimação principal, realizaram-se ainda duas análises de robustez que demonstraram, de forma geral, resultados diferentes. Esta investigação tem importância a nível académico, contribuindo para a literatura deste tema; a nível de gestão fiscal, interessante para gestores e investidores; e, a nível político, para o Estado e decisores políticos.
Over the years, the tax burden has been gaining weight in the lives of the Portuguese companies, making it crucial to study the effective tax rate (ETR) and its determinants. The aim of this dissertation is therefore to analyze the determinants of the ETR in Portugal. For this purpose, a sample consisting of an unbalanced panel of 352,816 Portuguese companies and 1,051,947 observations from four financial years (2019 to 2022) was extracted from the Sistema de Análise de Balanços Ibéricos (SABI). The results of this study suggest that larger, more profitable, more capital-intensive, and inventory-intensive companies have a lower ETR. In addition to the main estimation, two robustness analyses were also carried out, which generally showed different results. This research is important at an academic level, contributing to the literature on this subject; at a fiscal management level, interesting for managers and investors; and at a political level, for the State and policy-makers.
