Digital transformation in tax administration through the Coretax Administration System demands Civil Servants (ASN) possess adequate technical competencies. The Regional Human Resources Development Agency (BPSDMD) of South Sumatra Province organizes Tax Technical Guidance for treasurers and ASN. This study aims to analyze the implementation of Tax Technical Guidance in enhancing ASN competency at BPSDMD of South Sumatra Province. Using a qualitative descriptive approach, data were collected through observation, interviews, questionnaires, and documentation. Analysis was based on George C. Edward III's policy implementation theory (communication, resources, disposition, bureaucratic structure). Findings indicate that implementation has been moderately successful. Communication was clear, resources were supported by competent instructors and adequate facilities, disposition reflected commitment, and bureaucratic structure followed SOPs. However, technical disruptions in the Coretax system, participants' inadequate device readiness, and limited training coverage remain challenges. The study recommends improved training readiness, strengthened coordination with the Directorate General of Taxes, and expanded program implementation.
