How to Activate Coretax in Sukabumi: Verify Email and Phone

The Tax Service Office (KPP) Pratama Sukabumi held an assistance session on 14 Oct 2025 to guide taxpayers in activating their Coretax account and obtaining a DJP authorization code. The event took place at the Sukabumi tax office and included participants from the Balai Besar Perikanan Budidaya Air Tawar Sukabumi.

Coretax activation is a prerequisite for filing the next year’s Annual Tax Return; the registered email and mobile number must match tax records, otherwise taxpayers must first request a data change. Activation steps involve visiting ., entering the taxpayer’s ID (NIK), email, phone number, uploading a selfie, then validating and saving the information.

The DJP authorization code serves as an electronic signature for the tax return, making its acquisition essential for taxpayers. The assistance session aims to improve filing readiness and reduce data mismatches in future submissions.
