The implementation of the Coretax system in Indonesia’s tax reform continues to draw criticism. Chairman of the National Economic Council (DEN), Luhut Binsar Pandjaitan, has even urged President Prabowo Subianto to audit the system.

However, this situation raises a fundamental question: is Coretax truly effective in boosting state revenue, or does it instead pose structural weaknesses that hinder tax optimization?
