Confused about where to start registering for a Taxpayer Identification Number (NPWP) with Coretax? This application helps you UNDERSTAND and PRACTICE before registering for real on the official website coretaxdjp.pajak.go.id — so that when you fill out the actual form, you already know the process and won't get confused mid-way.
WHAT'S IN THIS APP:
Document Checklist
List of documents required before registering — different for Employees/Individuals and Businesses/MSMEs. Check them off one by one, and your progress will be saved automatically.
Step-by-Step Guide
A step-by-step explanation of the Coretax registration process, compiled based on official DGT documentation — from opening the portal to issuing your NPWP.
Form Filling Simulator
Practice filling out the complete registration form (Identity, Contact, Economic Data, Address, Photo Verification, etc.) in simulation mode. NO data is saved or sent anywhere — this is purely a practice session to help you familiarize yourself with the actual form.
FAQ & Help
Solutions to common registration issues (validation failure, selfie rejection, etc.), plus official contact numbers for Kring Pajak and Halo Dukcapil if you need further assistance.
