As of April 2026, the Dominican Republic’s fiscal ecosystem has been fundamentally reshaped by the full implementation of Law 51-23 on Electronic Billing. The Dirección General de Impuestos Internos (DGII) has transitioned to a “Digital-First” administration, where the validation of tax identifiers is no longer a periodic check but a real-time requirement for every transaction. The most critical change this year is that the “Large Taxpayer” transition period has concluded, making the issuance of e-CF (Comprobante Fiscal Electrónico) mandatory for nearly all commercial sectors. In this high-stakes environment, your 9-digit RNC is the mandatory anchor for compliance and operational legitimacy.
