ENThe purpose of this paper is to carry out a comparative analysis of the reporting obligations of SMEs in selected Eastern-European countries (Latvia, Lithuania, Poland, Russia, Ukraine). These are countries with different levels of economic development, but with a common political-economic ground, where the principles of market economy were introduced at a similar time. Micro, small and medium enterprises are an important element of European economies, both those within the EU as well as those outside it. The results of the analysis of macroeconomic data, which are presented in the article, will indicate signifi cance of this sector in Latvia, Lithuania, Poland, Russia and Ukraine. Literature studies and analysis of the national legal regulations allowed to indicate different ranges of the mandatory elements of the fi nancial statements and of the additional information which the entities from the SME sector must prepare in individual countries. The differences also exist in case of tax evidence and tax reporting. As a result, the scope of the fi nancial information for decision-making and for evaluation of the enterprises is not homogenous in the researched Eastern-European countries. This impedes comparability, however, it can also be a prerequisite to seek the best solutions and practices, not only for the reporting purposes, but also for constructing effective information systems meeting the needs of the managers.
