Coretax Account Activation Starts with Correct Email and Phone
December 5, 2025 • Ben Asmadeus

The Tax Office Pratama Kotabumi, together with KP2KP Menggala and the West Tulang Bawang Education Office, held a Coretax activation briefing on 13 November 2025 in Panaragan. The session targeted all school financial operators.
Tax educator Fadhlan Zalza Ridhallah explained that activating a Coretax DJP account is required for annual tax return filing from next year, replacing the DJP Online system. He urged taxpayers to verify that the email address and mobile number registered with DJP match their current contact details, as these are needed to receive the password‑creation link.
Once activated, taxpayers must obtain a DJP authorization code, valid for two years, to sign electronically under the ministerial tax regulation. Compliance with these steps is expected to streamline tax reporting and reduce reliance on the legacy DJP Online platform.
