Penguatan Literasi Coretax: Peran IKPI Sidoarjo sebagai Knowledge Center dan Mitra Strategis DJP dalam Pelaporan SPT Tahunan
Abstract
The implementation of the Core Tax Administration System (Coretax) represents an innovative step by the Directorate General of Taxes (DGT) to modernize tax administration in Indonesia. The transition of reporting from the legacy DJP Online system to Coretax in 2026 presents significant challenges for taxpayers, particularly regarding the understanding of complex data automation mechanisms. This community service activity aimed to provide practical knowledge to individual taxpayers and tax practitioners, specifically tax consultants, to accelerate self-reliance in filing Individual Income Tax Returns (SPT Tahunan). The implementation process was conducted systematically, beginning with internal capacity building through a Training of Trainer (ToT) program organized by the IKPI National Board, followed by an online technical briefing on March 7, 2026, via the Zoom platform. The results indicated that comprehensive material presentations and technical simulations of Coretax-based tax filing were highly effective in increasing participants' confidence and reducing psychological barriers toward new technology. The success of this technical briefing reaffirms IKPI Sidoarjo’s position as a knowledge center and a strategic partner of the DGT in ensuring the success of the national digital transformation agenda to support state revenue.
