Abstract

The aim of this paper is to provide a generalization of the Pfähler (1990) and Lambert (1989, 2001) decomposition that allows us to overcome some limitations of the original methodology. In particular, our proposal allows avoiding the problem of sequentiality when the tax has several types of deductions or allowances, sch edules or tax credits. In addition, our alternative decomposition is adapted to the dual income class of tax structures. Moreover, in order to adapt this methodology to real - world taxes, our alternative includes the re - ranking effects of real taxes, caused by the existence of differentiated treatment s based on non - income attributes. This theoretical proposal is illustrated with an empirical analysis for the Spanish Personal Income Tax reform enforced in 2007
