The document discusses the significant issue of smuggling and illicit trade in Ukraine, estimating that shadow imports could account for up to 15% of official imports, particularly in certain goods. It emphasizes the inadequacy of traditional customs enforcement methods, pointing out that only a small percentage of shadow imports are identified, and proposes a unified electronic tax invoice system to enhance monitoring and control over the introduction of goods into commerce. The proposed system aims to minimize smuggling by automating data exchanges between tax and customs authorities, thereby facilitating better regulation and reducing unfair competition.
