The DGT strives to create a strong, credible and accountable tax institution with effective and efficient business processes to increase state revenue. In early 2025, DGT has officially launched CORETAX to simplify tax reporting in Indonesia through digitalization. CORETAX has been implemented for reporting tax obligations starting from the 2025 tax year. Are you interested about CORETAX and how to operate it? Let’s explore the detail further!

What is CORETAX System?

To simplify tax reporting in Indonesia, the Directorate General of Taxes developed a system called CORETAX. Furthermore, this policy is governed by Presidential Regulation Number 40 of 2018 concerning the Tax Administration System Update. Hence, the government hopes that this system will enhance taxpayer compliance and increase state revenues.
