The tweet read: “Charla virtual: Declaremos juntos: Presentación de la Declaración Resumen Mensual de Clientes, Proveedores y Gastos EspecĆficos que no estĆ©n amparados en un comprobante electrónico

These communications form part of ongoing efforts by the Ministerio de Hacienda to inform stakeholders about procedural changes and compliance requirements. SIECA is an intergovernmental body that promotes economic integration among Central American countries. The DUCA-T document referenced in the first tweet is required for cross-border customs transit operations within Central America and must be generated and transmitted by drivers after prior registration.
Costa Rican tax authorities frequently offer educational sessions to clarify regulatory obligations for businesses and individuals. These webinars aim to increase compliance with tax rules such as proper declaration of transactions not backed by electronic invoices and understanding updated VAT regulations.
