The rules of the European Union suppose the value added tax as the only general excise tax. The need for harmonization of this tax in the existing EU member states is obvious, but the results in this field are not entirely convincing. Also the provision of services is a problematic field among others in the implementation of value added tax. It is essential to examine the issue of the value added tax, in this case, both the possibilities of the use of the self assessment system of the value added tax by the recipient of the service compared to the accounting of service including the value added tax by a provider of this service, even if the provider of service from the EU member state shall have a permanent establishment in other member state of the customer, but this establishment is not involved in the provision of the service, as well as the inclusion of services within the so-called extended guarantee to the taxable or exempt fulfilment, when the subject provides the technical support and the assistance to its customers, such as in the case of failures of agricultural machinery, which the provider had supplied to a subject in other member state. On the basis of empirical research, it is needed to assess the results of the harmonization efforts, to identify and recommend the direction in which the European Union should take in this field. The comparison of the individual European Union countries is important here. Value added tax is, regarding its features, still an unsurpassed excise tax, even if it has some weaknesses. The technique of the selection of this tax enables to discover the paid tax at all stages of treatment and it is very appropriate, due to its features for the use in international trade. It is therefore necessary to ensure the sufficient clarity, lucidity and equal conditions for players from the European Union on the basis of the development and adaptation of the rules of the value added tax set at the European Union level within each European Union country.
