De entre os impostos que integram o nosso sistema fiscal, o imposto sobre o rendimento das pessoas singulares, ocupa um lugar de destaque na arrecadação de receitas. A sua im-portância coloca este imposto sobre pressão, pondo em confronto a tributação dos rendi-mentos de capitais e a tributação dos rendimentos do trabalho. O modelo de base compreensiva em que assenta o imposto pessoal está semi dualizado, dado tributar de forma diferente os rendimentos com origem em investimentos financeiros, subtraindo-os ao englobamento com os restantes rendimentos. Com a presente dissertação, pretende-se averiguar se o imposto pessoal, face ao recorte constitucional, pode adoptar um modelo de base semi-dual. Esta configuração permitiria simplificar o imposto, assumir duas bases e coloca-lo em linha com os modelos de tributação pessoal adoptados em alguns países europeus. O estudo realizado permitiu concluir que é possível a adopção de um modelo de base semi-dual, desde que se mantenha, por opção do contribuinte, o regime do englobamento com os restantes rendimentos. A dúvida que manifestamos relaciona-se com a oportuni-dade da concretização da reforma. O momento delicado de finanças públicas que o nosso país atravessa, traz tarefas acrescidas aos políticos, fruto dos compromissos internacionais assumidos, o que pode obstar ao agendamento da reforma do imposto pessoal que muitos reclamam. Daí que o caminho a seguir seria o do aperfeiçoamento do actual modelo.

This Work Project analyzes the evolution of the Portuguese personal income tax system’s progressivity over the period of 2005 through 2013. It presents the first computation of cardinal progressivity measures using administrative tax data for Portugal. We compute several progressivity indices and find that progressivity has had very modest variations from 2005 to 2012, whilst from 2012 to 2013 there has been a relatively stronger decrease, excluding the impact of the income tax surcharge of the years 2012 and 2013. When this latter is included, progressivity of 2012 and 2013 decreases considerably. Analyzing the effective average tax rates of the top income percentiles in the income scale, we find that these rates have increased over the period 2010–2013, suggesting that an analysis of effective tax rates is insufficient to assess progressivity in the whole tax scheme.

We extend the linear reforms introduced by Pf¨ahler (1984) to the case of dual taxes. We study the relative effect that linear dual tax cuts have on the inequality of income distribution -a symmetrical study can be made for dual linear tax hikes-. We also introduce measures of the degree of progressivity for dual taxes and show that they can be connected to the Lorenz dominance criterion. Additionally, we study the tax liability elasticity of each of the reforms proposed. Finally, by means of a microsimulation model and a considerably large data set of taxpayers drawn from 2004 Spanish Income Tax Return population, 1) we compare different yield-equivalent tax cuts applied to the Spanish dual income tax and 2) we investigate how much income redistribution the dual tax reform (Act ‘35/2006’) introduced with respect to the previous tax.

The Scottish Parliament has the authority to make a balanced-budget expansion or contraction in public expenditure, funded by corresponding local changes in the basic rate of income tax of up to 3p in the pound. This fiscal adjustment is known as the Scottish Variable Rate of income tax, though it has never, as yet, been used. In this paper we attempt to identify the impact on aggregate economic activity in Scotland of implementing these devolved fiscal powers. This is achieved through theoretical analysis and simulation using a Computable General Equilibrium (CGE) model for Scotland. This analysis generalises the conventional Keynesian model so that negative balanced-budget multipliers values are possible, reflecting a regional “inverted Haavelmo effect”. Key parameters determining the aggregate economic impact are the extent to which the Scottish Government create local amenities valuable to the Scottish population and the extent to which this is incorporated into local wage bargaining.
