Taxing hard-to-tax markets

Tax enforcement costs constrain the government s ability to observe economic transactions, giving rise to hard-to-tax (HTT) markets. In these markets transactions are untaxed and consumers are better o¤ than in taxed markets. This paper studies a novel approach to combat evasion in HTT markets: consumer auditing, which rewards consumers for re- questing transaction receipts. We develop a Hotelling-type spatial model of sales taxation to analyze the welfare and distributional e¤ects of the implementation of this policy. We and that consumer auditing allows for a lower tax rate and greater provision of the public good in the economy. We show that this policy not only can enhance welfare, but also equalize utilities of consumers across markets

The effects of small firm tax incentives on employment levels

This paper aims to evaluate the impact on employment growth of a tax incentive program targeting Brazilian manufacturing small businesses (SIMPLES). This evaluation is conducted for two distinct periods: for the year 1997, when the program was first implemented, and for the year 1999, when the eligibility rule was modified to allow the eligibility of a broader group of firms. The evaluation takes into account two distinct channels through which the charted effects operate. The first is the employment variation in the firms that became eligible for the incentives, and the second is the change in the survival probability experienced by the same group of firms. Moreover, each of these channels can be activated either by the tax reduction dimension of the program or by its dimension of red tape simplification. Our results identify positive effects on employment growth for the tax incentive program only in the dimension of red tape simplification and its effects on the 1997 sample.

Yet another reason to tax goods

When, in a dynamic model, choices by an agent : i) are not observed, and; ii) affect preferences conditional on the realization of types, new and unexpected features come up in Mirrlees’ (1971) optimal taxation frame- work. In the simplest possible model where a non-trivial filtration may be incorporated, we show how these two characteristics make it neces- sary for IC constraints to be defined in terms of strategies rather than pure announcements. Tax prescriptions are derived, and we are able to show that uniform taxation prescription of Atkinson and Stiglitz fails to hold, in general. Clean results regarding capital income taxation are not easy to come about because usual assumption on preferences do not allow for determining which constraints bind at the optimum. However, in the most ’natural’ cases, we show that return on capital ought to be taxed.

Tax reform under fiscal stress: a CGE analysis of the Brazilian tax reform

In spite of a general agreement over the distortion imposed by the current Brazilian tax system, attempts to reform it during the last decade have faced several restrictions to its implementation. Two of these restrictions were particular binding: a) fiscal adjustment restriction (public sector debt cannot increase), b) fiscal federalist restriction (revenues from individual states and municipalities cannot decrease). This paper focuses on a specific reform that overcomes in principle the fiscal federalist restriction. Using Auerbach and Kotlikoff (1987) model calibrated for the Brazilian economy, I analyze the short and long run macroeconomic effects of this reform subject to the fiscal adjustment restriction. Finally, I look at the redistributive effects of this reform among generations as a way to infer about public opinion’s reaction to the reform. The reform consists basically of replacing indirect taxes on corporate revenues, which I show to be equivalent to a symmetric tax on labor and capital income, by a new federal VAT. The reform presented positive macroeconomic effects both in the short and long run. Despite a substantial increase in the average VAT rate in the first years after the reform, a majority of cohorts experienced an increase in their lifetime welfare, being potentially in favour of the reform.

The distribution of average and marginal effective tax rates in European Union member states

Macro-based summary indicators of effective tax burdens do not capture differences in effective tax rates facing different sub-groups of the population. They also cannot provide information on the level or distribution of the marginal effective tax rates thought to influence household behaviour. I use EUROMOD, an EU-wide tax-benefit microsimulation model, to compute distributions of average and marginal effective tax rates across the household population in fourteen European Union Member States. Using different definitions of ‘net taxes’, the tax base and the unit of analysis I present a range of measures showing the contribution of the tax-benefit system to household incomes, the average effective tax rates applicable to income from labour and marginal effective tax rates faced by working men and women. In a second step, effective tax rates are broken down to separately show the influence of each type of tax-benefit instrument. The results show that measures of effective tax rates vary considerably depending on incomes, labour market situations and family circumstances. Using single averages or macro-based indicators will therefore provide an inappropriate picture of tax burdens faced by large parts of the population.

Flypaper effect revisited : evidence for tax collection efficiency in Brazilian municipalities

This paper has two purposes. First, to construct efficiency scores in tax collection for Brazilian municipalities in 2004, taking into consideration two outputs: amount of per capita local tax collected -tax revenue- and the size of local informal economy- tax base. This methodology eliminates the price- effect of tax collection. Second, using the rules established on the Brazilian Constitution in 1988 to transfer unconditional funds among municipalities as instrument, to estimate the relationship between intergovernmental transfers and efficiency in tax collection. We conclude that transfers affect negatively the efficiency in tax collection, leading to a reinterpretation of the flypaper effect.

Do brazilian states engage in the fiscal war of ports? An empiric study of tax competition and an analysis of a natural experiment: the brazilian senate resolution 13/2012

O fim do ano de 2014 marcou o segundo aniversário da Resolução 13/2012 (R13) do Senado brasileiro. Grosso modo, R13 constituiu-se de um normativo do Senado cujo objetivo era o de por um fim na Guerra Fiscal dos Portos (FWP), uma competição fiscal entre os estados que se dá através da concessão de benefícios fiscais sobre operações interestaduais com mercadorias importadas de modo a atrair empresas importadoras para o território do estado concedente. R13 diminuiu o nível da tributação sobre tais operações, esperando com isso diminuir os lucros auferidos e a propensão das firmas de aceitarem tais regimes especiais de incentivação fiscal. Nada obstante, R13 gerou uma grande discussão sobre se os benefícios da atração de investimentos para um estado em particular superariam ou não os custos que esse estado incorreria em renunciar receitas tributárias em razão concessão desses benefícios fiscais. O objetivo do presente trabalho é o de dar uma contribuição a essa discussão, testando se um comportamento de interação estratégica entre estados, tal como aquele que supostamente ocorre no contexto da FWP, de fato emerge dos dados de importação coletados de janeiro de 2010 a maio de 2015, e, também, testando se a R13 de fato afetou tal comportamento de interação estratégica. Utiliza-se aqui um modelo de econometria espacial, no qual se especifica uma matriz de pesos que agrega o nível de importação das jurisdições concorrentes, organizando os dados em um painel de efeitos fixos. Os resultados sugerem que existe um comportamento de interação estratégica entre os estados e que a R13 de fato impactou tal comportamento.

Cash-cum-in-kind transfers and income tax function

This paper investigates income tax revenues response to tax rate changes taking into consideration that cash-cum-in-kind transfers are used as a redistributive package to the community. First, we show that when cash and in-kind transfers are not tied to be substitute instruments, a marginal income tax increase may unambiguously decrease the quantity supplied of labor (and tax revenues therein). Next, we show that whenever the government chooses the optimum provision for the publicly provided good the tax revenue function has a negatively-sloped part with respect to tax rates except for one case. Last, we consider Brazilian data - PNAD - from 1976 to 2008 to test our theoretical implications. Our estimations suggest a weak evidence in favor of the existence of a La er-type curve for Brazilian income tax revenues data. Moreover, wend that the actual average income tax rate seems to be below the estimated optimum level. In a shorter sample from 1996-1999, we nd evidence that labor supply decreases with tax rate when cash and in-kind transfers are in play. Using a pseudo-panel from the same shorter sample, we try to estimate the elasticity of taxable income, following Creedy and Gemmell (2012) and Saez et al. (2009). We explore a small tax reform between 1997 and 1998 that a ected only the higher income tax bracket, and evidence that Brazil is on the revenue reducing side of the La er Curve, at least for individuals in the higher income tax bracket.

A boa-fé objetiva na concessão dos incentivos fiscais / Humberto Antônio Barbosa Lima

This essay analyzes tax incentives concepts and existing discussions on national and foreing doctrine, especially in countries that influence our legal culture, such as Germany, United States of America, Spain, Italy and England, providing a detailed study about the requirements that must be observed to ensure that there be a legitimate concession of the same. All this using as argument the Constitutional Charter and the development of the Law, mainly through the principle of objective good faith, which acts as the limiting principle of administrative discretion in granting such tax incentives, as well as creative element of the new duties for the public managers in order to be more effective, efficient and transparent compliance with the pact between the government and society and the objectives pursued by the last. Always chasing a strong argument through a broad historical and philosophical analysis of the institutes discussed. Thus, through studies that reveal the necessary incidence of objective good faith in granting tax incentives to achieve the constitutional purposes, this work does not merely disclose what is wrong, but provides solutions to modify reality hitherto existing, ie, introduces ways to reduce the encumbrance of the odious and ineffective tax incentives in society and to redirect these values unjustly destinated for obscure interests to achieve the real reasons for the existence of tax incentives, especially economic development through the reduction of regional and social inaqualities and poverty eradication

Desvios de finalidade no Direito Constitucional Tributário brasileiro: aspectos estruturais e teleológicos da tributação na Constituição Federal de 1988

This work deals with considerations regarding common types of tax misuse that are present in the 1988 Brazilian Constitution. Thus, the work aims to unveil dogmatic features present in these practices that are considered illegal and are beset with vices such as power misusage. The research also aims to acknowledge the unconstitutionality issues regarding other guidance on behalf of goods that are responsible for the gradual positive approach realized by the 1988 Brazilian Federal Constitution. Thus, the work systematically used methodological procedures that aim to interpret the logical premises present as in the structure proposed by incidence rule matrix as in Ihering´s correction criteria considered as effective in itself. This is done also considering themes such as the Brazilian Public Tax legal matters. The work also performs a teleological debate of the Brazilian National Tax System as well as other related themes. It is understood that power misusage or any regards increase in aliquots. This can be observed in the quantitative criteria present in central aspects regarding taxes that are described in the constitutional regime either regulatory or induced nature, such as §1º, of the normative information present in article number 153 which is considered predominantly as tax raising such as pointed out in the 1988 Brazilian Constitution. On the other hand, it is seen that the type of misguidance with goods is understood as a practice that deviates as well as cuts connection with (rectius, unattaches) tax resources that are gathered and destined to specific constitutional purposes. At the end, the work deals with issues that aim to identify possible causes that lead to the use of norms and patterns that regulate such deviations. The research emphasizes ratio issues that are present in tax inspection proposals and invalidation that aim to restore the logical compatibility of these normative actions included in the Constitutional Tax Legal matters that was put forth by the 1988 Brazilian Federal Constitution
