The digitalization of public administration through e-government represents a significant transformation in how citizens access services and information, enabling faster, more secure, and efficient administrative procedures. By introducing information and communication technologies (ICT), e-government reduces bureaucratic barriers, speeds up administrative processes, and cuts costs, benefiting citizens, businesses, and public institutions. Key advantages include improved access to services, reduced administrative costs, increased efficiency and transparency, and minimized human errors. However, challenges such as low digital literacy and data security threats require additional investments in education and data protection. The European Union plays a crucial role in harmonizing administrative procedures among member states, providing a framework for secure and efficient data exchange and cross-border business. Examples from Croatia and Austria demonstrate the success of e-government implementation through projects such as e-Citizens, the ZUP IT system, and the oesterreich.gv.at platform, which facilitate easier access to services, greater transparency, and reduced bureaucracy. E-government is the foundation for the modernization of public services, reducing costs and increasing efficiency, but its success depends on continued investment in infrastructure, education, and data security.
