Avaliação da arrecadação dos principais impostos estaduais - ICMS e IPVA - em relação ao Produto Interno Bruto

Abstract

Aiming to understand the relationship between the collection of the major state taxes - ICMS (VAT) and IPVA - and GDP in all units of the Federation in the period 1997 to 2006, it is an expression statistic for estimating this relationship and a ranking showing the degree of affinity between the collection of taxes mentioned state and GDP statistics for the equation, using the simple linear regression with its main premises in order to understand this relationship, whereas the GDP reflects the size of the economy of each state. The data concerning the current GDP was taken from the IBGE site which was used for comparison with the collection of IPVA. The current GDP, also served as a basis for calculating the adjusted GDP, of which exports were removed (free of VAT) and imports added (taxed by ICMS) to compare with the ICMS through simple linear regressions, while the values of the collections the ICMS and IPVA were taken from the site CONFAZ, organ of the Ministry of Finance to disclose such data. In the results, the equations are seen statistics that could estimate the tax, in addition to providing the development of the ranking. The survey results showed that 77.78% of the units in the Federation there is a greater increase in the collection of VAT and IPVA on the increase in GDP, ie, in most states to collect such taxes had a greater proportional increase that the increase of wealth in their economies.
