Activation of a corporate Coretax account can only be done if the 16-digit NPWP (Tax Identification Number) has been registered in the Directorate General of Taxes system. The process is 100 percent online through the official DGT portal, with contact data and digital identity verification. If the data is synchronized, activation can be completed within minutes.
As tax consultants, we at vOffice frequently assist corporate clients, including foreign-owned limited liability companies (PT PMA), in understanding the activation stages to prevent failures during the process.
What Is Coretax and Why Must It Be Activated?
Coretax is the latest tax administration system developed by the Directorate General of Taxes to integrate tax reporting, payment, and administration into a single digital platform.
For corporate taxpayers, a Coretax account serves as the primary access point for filing Annual and Periodic Tax Returns (SPT), generating a DGT Authorization Code, and applying for VAT-registered status (PKP).
Requirements for Activating a Corporate Coretax Account
Before starting, make sure you meet the following requirements:
- A valid and active 16-digit corporate NPWP
- An email address and mobile number registered in the DJP Online system
- Camera access for selfie verification
If your email address or mobile number is not updated, you can contact Kring Pajak 1500200 to update your data.
For new companies that do not yet have an NPWP, registration must be completed separately by attaching the deed of establishment, the legalization decree from the Ministry of Law and Human Rights, and notary details.

Required Documents for New Registration
If you do not yet have an NPWP, prepare:
- Company deed of establishment
- Legalization Decree from the Ministry of Law and Human Rights
- Notary/PPAT NIK details
- Business location documents for VAT registration (PKP)
The system will validate the data through integration with AHU and Dukcapil.
Common Issues and How to Solve Them
Below are common issues encountered during corporate Coretax activation and their solutions:
- Data Mismatch: Differences in names or numbers in the NPWP may cause activation failure. Ensure your data matches the Dukcapil database.
- Email Not Received: Check your spam folder or ensure your email account is still active.
- Account Already Registered: Use the Forgot Password menu to reset your account.
- Server Overload: Avoid peak periods from March to April during tax reporting season.
After activation, generate a DGT Authorization Code for electronic SPT signing. Without this code, tax filing cannot be processed.
