Through the accession negotiations and accession to the European Union, Croatia has been offered numerous opportunities for financing from pre-accession and European structural and investment funds, and thus new opportunities for economic growth and development. Micro enterprises play a significant role in the economy because they are generators of employment, drivers of development and innovation, contribute to increasing the competitiveness of the entire economy and represent the majority of all registered companies in Croatia. In Zadar County, micro-enterprises accounted for 91.5% of the total number of registered business entities in 2018., employing 35.5% of employees. Although grants have been available for a relatively long time, micro-entrepreneurs in Zadar County have not utilized enough given possibilities. Only recently, Zadar entrepreneurs have been increasingly applying for grants. This paper analyzed the income and the number of employees, micro-enterprises in the Zadar County area that were granted EU grants, to determine the impact of grants in the years following the withdrawal. The analysis covers micro companies that are required to make public the annual financial statements, and in order to test the hypotheses, the necessary data were collected from FinInfo. In addition, the paper provides an overview of EU programs and funds, with an emphasis on entrepreneurship opportunities, and an overview of the role and importance of micro-entrepreneurship as a whole, and in particular of Zadar County.
