Abstract

This research aims to verify whether firms that operate in several different business sectors are more tax aggressive in comparison to firms that operate in a single or a few segments. The study analyzes a sample of 4,280 firms/year, listed in the Brazilian stock exchange B3 in the period from 2010 to 2017. It was observed that most of the companies operate in one or two business segments. To verify the existence of a relationship between diversification and tax aggressiveness, we used a multiple linear regression model with fixed effect panel data for firm and year. Also, we used the logit model with binary response for the explanatory variable. Two measurements of tax aggressiveness were applied, the ETR (effective tax rate) and the ETR LONG (long-run effective tax rates). This type of research is an innovation in Brazil, not yet explored in the literature. The results showed that more diversified firms are more likely to be tax aggressive, in comparison to single-segment firms. Therefore, the results indicate that among Brazilian listed companies, there is a positive relationship between the number of segments in which they are listed and the level of tax aggressiveness. Among the main contributions of the research, we emphasize the better understanding of the phenomenon of tax aggressiveness, its causes and determinants, implications for information users (particularly tax regulators), and implications for the management that identifies a possible tax advantage in corporate diversification.
