The Servicio de Impuestos Internos (SII) unveiled a newly designed portal dedicated to Territorial Tax, aimed at simplifying complex concepts and providing direct support to taxpayers throughout Chile. The portal, launched on June 24, 2026, consolidates a wealth of information, including detailed explanatory guides, interactive tools, and FAQ sections that address common compliance questions. By presenting material in a user‑friendly format, the SII hopes to reduce confusion surrounding territorial taxation rules, which have become increasingly relevant as businesses expand their operations across borders. Key features of the portal include step‑by‑step calculators that help users determine their tax liabilities based on the source of income, as well as a searchable database of recent rulings and interpretative notes. In addition, the portal offers a live chat service staffed by tax specialists who can answer queries in real time, ensuring that taxpayers receive timely and accurate assistance. The launch forms part of a larger initiative to modernize digital services offered by the SII, reflecting its commitment to accessibility and transparency. Early feedback from users indicates that the portal has already contributed to more efficient tax planning and reduced the likelihood of inadvertent non‑compliance, thereby supporting both taxpayers and the overall integrity of the tax system.
