Coretax System: Key Benefits and Step-by-Step Guide to Efficient Tax Administration

Coretax System or CTAS is a tax administration system that is part of the government's efforts to implement tax reform in Indonesia. Referring to the official website of the Direktorat Jenderal Pajak (DJP), tax reform includes five main pillars, namely simplification of organizational structure, provision of human resources with integrity, utilization of data-based information technology, simplification of business processes, and legal certainty through simplification of tax regulations.

Starting in 2025, the Direktorat Jenderal Pajak (DJP) will implement the Coretax Administration System (Coretax System) to improve efficiency and transparency in tax administration in Indonesia. As the legal basis for the implementation of this system, the Ministry of Finance (MoF) has issued Minister of Finance Regulation No. 81 Year 2024, which regulates various aspects of taxation related to the implementation of the Coretax System.

This digital transformation is expected to simplify business processes in the implementation of tax administration, both for the Directorate General of Taxes (DGT) in carrying out its duties and for taxpayers in fulfilling their tax obligations.

The benefits of the Coretax Administration System (CTAS) include:

• Simpler, because it uses an omnichannel and borderless approach, users can access the system through various channels such as desktop, mobile, and other devices without any regional restrictions.
• More practical, because the system used is universal, a single platform can meet the various needs and functions required by an organization.
• Faster, because the system and data have been integrated, reduce delays and errors, so that administrative processes can be carried out more quickly and responsively.
• More effective, because access to the system becomes easier, users can quickly find the necessary information and perform tasks without a hitch.

With CTAS, the main difference compared to the previous tax administration system lies in a more automated and integrated process, so that tax administration becomes more efficient and easier to run.
