This study of entrepreneurship in Europe is a greatly expanded and updated version, in English, of the author's thesis published in Dutch in 1996. Its analysis focuses on bottlenecks and cross-border problems confronting European entrepreneurs in the areas of income tax, corporate income tax, and value-added tax. Four countries are chosen as representative of all the tax systems existing within the EC: The Netherlands, Germany, France and the United Kingdom. The author spares no detail in his examination, explaining such important elements and distinctions as the following: how the entrepreneur is viewed under the varying tax regimes and in the different countries; entrepreneurship and the professions; incentives; sources of income; partnerships; companies and shareholders; calculation of taxable profit; justification for a separate corporate income tax; taxation of foundations and societies; and the possibility of fiscal unity among Member States for VAT purposes.
