Coretax Officially Becomes Indonesia’s Main Tax Administration System

Starting in July 2026, Indonesia’s Directorate General of Taxes (DGT) has officially designated Coretax as the primary platform for tax administration. As a result, nearly all tax-related administrative processes are now being carried out through a single integrated system.

Director General of Taxes Bimo Wijayanto stated that Coretax has become the backbone of Indonesia’s tax administration. Over time, legacy systems will be phased out, and all tax administrative activities will be conducted exclusively through Coretax.

What Tax Services Are Now Available Through Coretax?

Coretax integrates a wide range of tax administration services into one centralized platform, including:

• Tax filing and reporting
• Taxpayer monitoring and supervision
• Tax collection
• Tax audits and law enforcement
• Tax objections and appeals

These services are being gradually migrated from legacy systems, with Coretax becoming the sole platform for processing tax administration in the future.

Benefits of Coretax for Taxpayers

Coretax is designed to simplify tax administration by providing digital access to tax data and documents anytime and anywhere. Users can securely access the system through laptops, tablets, or smartphones without relying on physical documents or office-based systems.

This digital approach improves efficiency, enhances accessibility, and streamlines the overall tax compliance process for both individuals and businesses.

Positive Impact Since the Implementation of Coretax

Since its implementation, Coretax has shown encouraging results across several key tax administration indicators:

• Tax invoice issuance increased by 4.62%.
• Unified Withholding Tax (PPh Unification) certificates rose by 110.72%.
• Article 21 withholding tax certificates increased by 17.79%.
• Individual Income Tax (PPh) revenue surged 272.26%, reaching IDR 8.78 trillion.
• Corporate Income Tax gross revenue increased 56.8% to IDR 25.11 trillion.

Coretax also enables seamless data sharing across units within Indonesia’s Ministry of Finance, allowing tax supervision to become faster, more accurate, and better integrated.

In addition, the platform has successfully supported the filing of approximately 13.6 million Annual Tax Returns (SPT), with an average of 82,000 tax returns submitted each day.

A Major Step Toward a Modern Digital Tax Administration

The nationwide implementation of Coretax marks a significant milestone in Indonesia’s tax administration reform. By consolidating tax services into one integrated platform, the government aims to deliver a system that is more efficient, transparent, user-friendly, and capable of providing greater legal certainty for taxpayers.

For individuals and businesses alike, understanding and adapting to Coretax will be essential to ensuring smooth tax compliance under Indonesia’s evolving digital tax ecosystem.

Conclusion

As of July 2026, Coretax has become the central platform for Indonesia’s tax administration. This transition represents a significant step toward a smarter, more integrated, and digitally driven tax system.

Taxpayers are encouraged to familiarize themselves with Coretax and begin using the platform to ensure efficient, compliant, and seamless tax administration in the years ahead.
