Coretax Offline for Six Hours Starting Night of Dec 9

The Directorate General of Taxes (DGT) announced that the Coretax application will be inaccessible from 23:00 WIB on Tuesday, 9 December 2025 until 05:00 WIB on Wednesday, 10 December 2025. During this period, all Coretax services are disabled.

The downtime is intended to increase system capacity and improve service reliability for taxpayers. Coretax is a new system that replaced SIDJP at the start of 2025 under Presidential Regulation No. 40/2018.

This temporary shutdown may affect taxpayers who normally file or check data via Coretax, so they should adjust their schedules accordingly. DGT apologizes for the inconvenience and will restore the service once maintenance is completed.
