Indonesian Finance Minister Tackles Coretax Challenges, Promises System Improvements

Background on Coretax Implementation

The Indonesian Ministry of Finance, led by Minister Purbaya Yudhi Sadewa, has been addressing recent challenges with the new Coretax system. The Coretax platform is a critical component of Indonesia's tax reporting infrastructure for the 2025 tax year.

Activation Challenges and Ministerial Response

Minister Purbaya acknowledged that independent activation of Coretax accounts has proven problematic for some taxpayers. He revealed receiving complaints from individuals who struggled with the self-activation process. In response, Purbaya has instructed the Directorate General of Taxes (DJP) to develop clearer guidelines and provide comprehensive training to assist taxpayers.

Key Features of Coretax Implementation

1. Mandatory Activation: All taxpayers must activate their Coretax accounts before submitting their 2025 tax returns
2. Multiple Activation Methods: Taxpayers can activate accounts either independently or through tax offices
3. Technical Support: DJP has promised assistance for those facing technical difficulties
4. Security Measures: The system requires Kode Otorisasi/Sertifikat Elektronik (KO/SE) for secure access

Official Guidance and Deadlines

The DJP issued circular PENG-54/PJ.09/2025 on December 29, 2025, outlining specific guidelines for Coretax activation. The circular emphasized that while there's no strict deadline for activation, taxpayers are encouraged to complete the process early to avoid congestion during peak reporting periods.

Ministerial Oversight and System Management

Minister Purbaya confirmed that the Coretax system has been under the direct supervision of the Ministry of Finance since mid-December 2025. The ministry is working to resolve remaining technical issues while maintaining system integrity.

Implications for Taxpayers

The successful implementation of Coretax is crucial for Indonesia's tax administration modernization efforts. While initial challenges have arisen, the ministry's proactive response aims to ensure a smoother experience for taxpayers in the long run.
