Cortex DJP Tax Billing Guide

Jul 9, 2025

Overview

This tutorial explains how to create a billing code for tax payments using the Cortex DJP application, effective starting January 2025, replacing the previous DJP Online system.

Introduction to Cortex DJP

  • Cortex DJP launches in January 2025 as the new platform for annual SPT reporting and PPNPH billing code generation.
  • Unlike DJP Online, Cortex DJP uses email and phone number for login, without requiring a PIN.
  • Users must activate their taxpayer account if they do not already have a user ID.

Account Access and Login Process

  • Access the platform via corteekdjp.co.id.
  • Log in with nickname or NPWP, password, and security code.
  • The e-profile page displays sensitive taxpayer information such as profile, NIK, representatives, and NPWP status.

Creating a Billing Code

  • Navigate to the payment menu and select “billing code self-service.”
  • Confirm taxpayer details, including name and address.
  • Choose the appropriate KAP KJS based on the tax to be paid.
  • Select the tax period starting from January 2025 (previous years are not available).
  • Input the tax amount and optionally add a description.
  • Download the billing code for further use.

Managing and Paying Billing Codes

  • Unpaid billing codes can be accessed in the “list of unpaid billing codes.”
  • Details include currency, total tax amount, and active period (e.g., until February 7, 2025).
  • Expired billing codes cannot be used for payment.
  • Payments can be made through PT Bank Mandiri, PT Bank Negara Indonesia, or PT Bank Rakyat Indonesia.

Payment Process Details

  • Download and review the billing code containing taxpayer information, payment amount, description, and billing code itself.
  • Payment can be completed via Brimo or Lipin Bay Mandiri apps under the tax payment or tax store sections.
  • Enter the billing code as prompted and follow the payment instructions.

Key Dates / Deadlines

  • Cortex DJP is effective for tax periods beginning January 2025.
  • Example billing code active period: valid until February 7, 2025.
