The Indonesian Tax Authority (DJP) is proactively encouraging state-owned banks to activate their Coretax system through an online socialization event held on December 12, 2025. The initiative aims to facilitate the annual tax return reporting for 2025, starting January 1, 2026. Key participants include major state-owned banks such as Bank Mandiri, BRI, BNI, and BTN through their association Himbara.
In preparation for the 2025 annual tax return reporting through the Coretax system starting January 1, 2026, the Indonesian Tax Authority (DJP) under the Ministry of Finance has taken proactive measures. The DJP organized an online socialization event on December 12, 2025, specifically targeting major state-owned banks through their association Himbara.
The socialization event included key state-owned banking institutions: Bank Mandiri, Bank Rakyat Indonesia (BRI), Bank Nasional Indonesia (BNI), and Bank Tabungan Negara (BTN). The primary focus was on encouraging these institutions to complete the activation of their taxpayer accounts and create authorization codes/electronic certificates (KO/SE) through the Coretax system.
The Coretax system represents a significant modernization effort by DJP to streamline tax reporting processes. By activating this system, banks and other corporate taxpayers will be better prepared for the upcoming tax reporting season. The initiative demonstrates DJP's commitment to improving tax compliance through digital infrastructure.
For the participating state-owned banks, this proactive engagement with DJP is crucial for ensuring compliance with upcoming tax regulations. Successful activation of the Coretax system will enable these institutions to efficiently manage their tax obligations, potentially setting a precedent for other corporate taxpayers in Indonesia.
