The aim of this work is the analysis of anti-crisis measures in taxation in the European Union and their impact on the tax burden for the following years. The work is focused on all twenty-seven European members' states and for better illustration were chosen four member states, namely France, Germany, Spain and Romania. At the work are used the latest data available and practical examples are given too. For determination of tax systems before the crisis in selected countries are used descriptive methods, analysis of anti-crisis measures in fiscal policy and an analysis of changes in taxations for the years 2009 and 2010 and their comparison with the year 2008 followed with the focusing on changes in the tax burden. The result of description of tax systems for 2008 is the claim that relatively high tax burden is in analyzed countries except in Romania.The reaction to negative changes in the economy, financial crisis caused, were changes in the tax systems in most of European Union countries especially in modification in tax bases and tax rates. These changes have led to reductions of tax burden in the EU. This trend is expected for next years too, but it is expected the lack of tax revenues will be replaced mainly by raising indirect taxes.

Le début du siècle connaît une forte accélération des mouvements de capitaux et de personnes à l'échelle planétaire. Les transferts de résidence fiscale des personnes physiques fortunées se multiplient entre les pays à fiscalité élevée et les juridictions offrant un système fiscal attractif. Les délocalisations physiques croissantes entre la France et la Suisse en sont une démonstration concrète. L'objectif de ce travail de recherche est de traiter en détail les problématiques de transfert de résidence des personnes fortunées entre la France et la Suisse et leurs conséquences fiscales. Le dispositif fiscal français, souvent perçu comme inique motive parfois des décisions d'expatriation qui ne sont plus simplement fiscales. Il convient de confronter cette perception à une réalité objective. L'établissement de la résidence fiscale en Suisse permet de bénéficier d'un dispositif fiscal différent, dont l'imposition sur la dépense est une démonstration particulièrement attractive pour les grandes fortunes. Malgré tout, le transfert de résidence en Suisse ne résout pas l'ensemble des problématiques fiscales ou patrimoniales des personnes fortunées. Il présente également des contraintes et limites. Pour cette raison, un certain nombre d'expatriés va décider un éventuel retour en France ou un transfert subséquent dans une juridiction alternative, plus attractive encore que la Suisse. Nous examinerons ces juridictions concurrentes et adopterons un point de vue critique sur les dispositifs fiscaux français et suisses en présence, avec des propositions de réforme ou d'adaptation en vue de restaurer ou préserver la compétitivité de ceux-ci sur un plan international. / The beginning of the 21th century witnessed a prodigious acceleration of the movements of capital and persons on a worldwide scale. Transfers of tax residence by High Net Worth lndividuals dramatically increased in particular, from high tax countries to jurisdictions offering attractive levels of taxation. The sheer number of French residents expatriating to Switzerland is a testimony of this trend. The objective of this research work is to cover precisely the issues related to the relocations of High Net Worth Individuals from France to Switzerland and their tax consequences. The French tax system, often perceived as complex, inequitable sometimes motivates decisions of expatriation which are not only related to fiscal reasons. It is the author's belief that it is necessary to confront this perception with the legal and factual reality and to explore i which conditions an expatriation from France can be managed. The transfer of domicile to Switzerland enable wealthy individuals to benefit from an at1ractive tax regime. Nevertheless, moving to Switzerland does not solve all of a wealthy expatriate's tax or patrimonial issues. Relocation entails constraints and limits. For that reason, some French expatriates will decide on a possible return to France or alternatively to jurisdiction even more attractive than Switzerland. We shall examine these rival jurisdictions and compare with a critical eye the French and Swiss tax systems in presence, with proposals for reform or adaptation with a view to restore or preserve their respective competitiveness on an international scale.
