Effects of flat tax reforms in Western Europe on equity and efficiency

The flat income tax has become increasingly popular recently, yet its implementation is limited to Eastern Europe. We analyse the distributional and e? ciency effects of flat tax scenarios for Western European countries. Our simulations show that flat tax rates required to attain revenue neutrality with existing basic allowances improve labour supply incentives. However, they result in higher inequality and polarisation. Flat rates necessary to keep the inequality levels unchanged allow for some scope for flat taxes to increase both equity and e? ciency. Our analysis suggests that Mediterranean countries are more likely to benefit from flat taxes. --Flat tax reform,income distribution,work incentives,microsimulation

Income underreporting based on income expenditure gaps: Survey vs tax records

We estimate the extent of income underreporting among working households, using data from an income survey linked with individual tax records for Estonia. Income underreporting is inferred from consumption propensities, following and extending the method by Pissarides andWeber (1989). Our dataset allows us to assess the validity of the key assumption in related studies that survey income corresponds to income reported to the tax authority. Our results show large underreporting of earnings by the self-employed and also substantial underreporting of earnings by private sector employees on the basis of register income, while a much smaller scale of non-compliance is detected for self-employed and no underreporting for private employees using survey incomes. This suggests that previous studies applying this methodology to survey data have underestimated the extent of non-compliance

The Distributional Impact of In Kind Public Benefits in European Countries

International comparisons of inequality based on measures of disposable income may not be valid if the size and incidence of publicly-provided in kind benefits differ across the countries considered. The benefits that are financed by taxation in one country may need to be purchased out of disposable income in another. We estimate the size and incidence of in kind or "non cash" benefits from public housing subsidies, education and health care for five European countries using comparable methods and data. Inequality in the augmented income measure is dramatically lower than in disposable income, with the effects of the three components varying in importance across countries. Adapting equivalence scales to take proper account of differences in needs for health care and education across population members reduces the scale of the effect, but does not eliminate it.inequality, in kind transfers, cross-national comparisons

The distributional effects of taxes and transfers under alternative income concepts: The importance of three 'I's

This paper investigates how the distribution of income changes when the standard definition of disposable income is replaced by an extended income concept which takes into account the three 'I's: indirect taxes, imputed rent, and in-kind benefits. Second, it assesses how sensitive the distributional effects of each tax-benefit instrument are to the choice of income concept. The analysis covers three European countries (Belgium, Greece and the UK) characterised by substantially different tax-benefit systems, giving a stronger base for generalising the results. The main findings are that the overall redistributive effect of the tax-benefit systems depends heavily on the income concept considered and the differences across countries are smaller when considering the extended income distribution. Moreover, the common use of a narrower income concept, such as the disposable income, can lead to the overestimation of the redistributive effect of the cash tax-benefit instruments (in relative terms), the extent of this varying across countries, due to the size and distribution of three 'I's and the adoption of the needs-adjusted equivalence scale

Europe Through the Crisis: Discretionary Policy Changes and Automatic Stabilizers

Tax‐benefit policies affect changes in household incomes through two main channels: discretionary policy changes and automatic stabilizers. We study their role in the EU countries in 2007–14 using an extended decomposition approach. Our results show that the two policy actions often reduced rather than increased inequality of net incomes, and so helped offset the inequality‐increasing impact of growing disparities in gross market incomes. While inequality reductions were achieved mainly through benefits using both routes, policy changes to and the automatic stabilization response of taxes and contributions raised inequality in some countries and lowered it in others

Tax evasion and measurement error: An econometric analysis of survey data linked with tax records

We use income survey data linked with tax records at the individual level for Estonia to estimate the determinants and extent of income tax compliance in a novel way. Unlike earlier studies attributing income discrepancies between such data sources either to tax evasion or survey measurement error, we model these processes jointly. Focussing on employment income, the key identifying assumption made is that people working in public sector cannot evade taxes. The results indicate a number of socio-demographic and labour market characteristics, which are associated with non-compliance. Overall, people in the bottom and the top part of earnings distribution evade much more and about 12% of wages and salaries in total are underreported, which is very substantial for a major income source subject to third party reporting and tax withholding
