MUC BIJAK Vol. 6: A Comprehensive Guide to Filing Corporate Annual Tax Returns via Coretax
JAKARTA. As the 2025 Fiscal Year nears its end, the Directorate General of Taxes (DGT) has officially released guidelines for completing the Annual Income Tax Return (SPT) for both individual and corporate taxpayers.
These guidelines respond to the significant changes introduced with the rollout of Coretax, the integrated tax administration system that took effect in early 2025. The system brings major updates to tax reporting, including new forms, attachments, and various technical details, marking a departure from the previous system.
Since its implementation, Coretax has served as a milestone in Indonesia’s digital tax administration transformation. However, the system has also introduced several challenges for both the tax authority and taxpayers.
The DGT continues to make adjustments and improvements to ensure optimal system performance. Nevertheless, without proper understanding and adequate education, the risk of errors in filing the Annual Tax Return remains, especially for corporate taxpayers with complex transactions.
To support taxpayers in adapting to these changes, MUC Consulting is hosting the 6th edition of its MUC Bicara Pajak (MUC BIJAK) webinar, titled “A Step-by-Step Walkthrough of Filing Corporate Annual Tax Returns via Coretax.”
Why This Topic Matters
The implementation of Coretax brings fundamental changes to tax reporting processes. These changes are not only administrative but also affect reporting workflows, data validation, and attachment synchronization.
For both companies and individuals, understanding the new formats and reporting flow is essential to ensure compliance and avoid data input errors.
Early preparation is key. Understanding how to complete the Annual Tax Return through Coretax will help taxpayers reduce mistakes and maintain proper tax compliance.
