The article describes how the Directorate General of Taxes (DJP) has partnered with the West Java provincial government to reinforce fiscal synergy that safeguards regional surplus and enhances tax collection performance. The collaboration focuses on improving the efficiency of tax administration, expanding the tax base, and adopting data‑driven strategies to identify revenue gaps. By integrating DJP’s analytical tools with provincial financial planning, the agencies aim to sustain the already‑observed surplus in West Java, ensuring that the region retains a healthy fiscal buffer while still delivering public services. A key outcome highlighted is the 18.5 percent growth in tax receipts for West Java’s third‑tier tax categories, reflecting the positive impact of coordinated policies such as streamlined registration processes, targeted outreach to small‑and‑medium enterprises, and stricter enforcement against under‑reported incomes. The article also underscores the commitment of both parties to maintain transparent reporting and to continuously monitor tax trends, which enables proactive adjustments to tax rates and incentives. Additionally, the partnership includes capacity‑building programs for local tax officials, training on modern audit techniques, and the adoption of digital platforms for filing and payment, which together are expected to further boost compliance and reduce evasion. Overall, the joint effort is portrayed as a model for other provinces seeking to strengthen their fiscal resilience through public‑private cooperation and strategic use of technology.
