Defining Coretax and the 2026 Rollout Timeline
The Directorate General of Taxes recently launched a unified digital platform. This system is known as the Core Tax Administration System. It integrates every aspect of the revenue cycle.
The platform became operational for monthly periods in early 2025. The most significant change arrives with the 2026 reporting season. All annual returns must now use this system.
Legacy channels like DJP Online are phased out. You can no longer submit manual forms for returns. Electronic filing is the only legal pathway for taxpayers now.
Taxpayers registered before 2025 were urged to verify their data. If you missed this window, activate your account immediately. Statutory deadlines are approaching for all registered entities.

KEP-67/PJ/2025 allows for the nullification of administrative penalties. If technical issues within Coretax cause a late filing, you are exempt. You must prove the delay was not your fault.
This relief is time-limited and tied to specific periods. You must still file and pay by the extended dates. Missing the extended deadline will result in standard fines.
Authorities may cancel penalty letters at the regional level. This means the government can remove fines without a request. This happens if the system failure is widespread.
