Effects of the electronic invoice program on the increase of state collection

Abstract

This article aims to verify if the implementation of the Electronic Invoice program (EI), generated an increase in the collection in the state of Goiás, Brazil. For the research, means test analysis (t-test) was used along with the estimation of regressions difference-in-differences. The results indicated that the average collection in the state of Goiás was statistically higher in the period after the implementation of EI and that the increase in the collection from companies required to issue EI was superior to the collection from those not required to during the period of investigation. Therefore, although the main focus of EI is not the increase in tax collection, it can be observed that the institutionalization of a program of standardization and sharing of fiscal documents included improvements in the inspection processes of the tax administration, increasing the collection of state taxes through the reduction of tax default.
