The 2025 Tax Volunteers for the Nation (Renjani) Program at Politeknik Negeri Batam involved 389 volunteers from the D3 Accounting and D4 Managerial Accounting study programs, who participated in four main activities: Annual Tax Return (SPT) assistance, Business Development Services (BDS), digital public relations, and additional supporting tasks. The program was implemented through close collaboration between the Polibatam Tax Center and the Regional Office of the Directorate General of Taxes (DJP) of Kepulauan Riau, with assigned duty schedules for morning-class volunteers and independently managed activities for evening-class and industry-based students. Throughout the implementation period, the program achieved notable outcomes, including 13,272 SPT assistance activities, 238 BDS activities, 22,676 digital public relations outputs, and 272 supporting activities. These achievements reflect Polibatam’s significant contribution to expanding tax education services, supporting MSMEs, and providing comprehensive practical learning experiences for students. This impact also positioned the Polibatam Tax Center third nationally among 565 Tax Centers in Indonesia. Despite the impressive results, several challenges emerged, including unequal contributions due to limited duty hours, variation in digital content quality, and the need for enhanced technical guidance. Additionally, some students lacked Renjani accounts or did not participate in activities. These findings underline the importance of strengthened coordination, administrative discipline, and improved internal monitoring. Overall, the Renjani 2025 program provides substantial benefits for the DJP, the public, MSMEs, students, and the Polibatam Tax Center in advancing national tax literacy and compliance.
