Abstract: This paper analyzes the legal, economic, and practical effects of implementing the Fiscalization 2.0 reform in the Republic of Croatia, with a particular focus on micro and small enterprises. The legal framework of Fiscalization 2.0 is defined by the proposed new Fiscalization Act from 2025, which clearly outlines obligations and deadlines for entrepreneurs, aligning national legislation with European standards. However, it simultaneously creates additional regulatory burdens for micro and small enterprises. A qualitative analysis was conducted using semi-structured interviews with a sample of 15 micro and small entrepreneurs operating across various sectors. The primary objective of this research was to identify key challenges, costs, benefits, and institutional support during the implementation of the new fiscalization system based on electronic invoices (e-invoices). The findings indicated the main barriers to digital fiscalization implementation, such as technical system complexity, additional financial costs, and insufficient education and informational support. Concurrently, micro and small entrepreneurs highlighted benefits like increased business transparency, reduced administrative burden, faster invoice processing, and enhanced digital literacy. Despite initial challenges, the long-term potential of the fiscal system's digital transformation is significant, provided that adequate institutional support and timely education for entrepreneurs are ensured.
