The Shift to Coretax and TAM
Since January 1, 2025, the fiscal landscape has transformed completely. The launch of Coretax, or the Core Tax Administration System (CTAS), marks the end of legacy systems. Old portals like DJP Online are being phased out for current reporting.
The updated filing requirements demand immediate attention from all corporate entities. Every PT PMA must now operate within this unified digital ecosystem to remain compliant. This is not just a cosmetic update to the website interface.
It is a fundamental structural change to how tax data is processed and stored. Taxpayer Account Management (TAM) is the heart of this new system. It consolidates every interaction your company has with the tax office into one “tax account.”
This account links your registration data, payment history, and filing records. It provides a single source of truth for both you and the authorities regarding your compliance status. Accessing this system requires updated authentication protocols.
You must link your NIK to your NPWP and set up secure Coretax credentials immediately. Without this integration, you cannot access critical filing menus. The Directorate General of Taxes has published technical guidelines for this process.
For tax years starting 2025, you must discontinue using the old e-Filing channels. The current tax form requirements now mandate using the Coretax portal for all annual submissions. The substantive form remains the familiar Formulir 1771.
However, it is now presented in a structured XML format directly within the Coretax interface. The filing workflow has changed significantly from previous years. You must now complete the Induk SPT (main form) first.
This action then triggers the specific attachment fields required by the system. These attachments are critical for a compliant PT PMA operating in Bali. You must prepare full annual financial statements, including your balance sheet and profit and loss report.
The system also requires detailed summaries of your Master File and Local File. This applies if your entity engages in significant related-party transactions under transfer pricing rules. Failure to upload these specific structured attachments will block your submission.
The system automatically validates data completeness before allowing you to finalize the return. For the tax year 2025, the deadline remains April 30, 2026. Late filing triggers an administrative penalty of IDR 1,000,000 plus daily interest.
The monthly reporting cycle has also migrated fully to Coretax. The updated filing rules have integrated various monthly returns into streamlined menus. The SPT Masa PPh 21/26 covers employee and non-resident withholding.
This form reflects the calculations mandated by PMK 168/2023 regarding benefits in kind. You must report cash salaries and taxable facilities provided to staff. This includes housing or transport provided to your employees in Bali.
Value Added Tax (PPN) reporting has shifted significantly under the new system. The standalone e-Faktur application is now integrated into the Coretax PPN reporting module. This integration simplifies the crediting of input VAT against output VAT.
The system automatically pulls data from your transaction ledger to populate the return. Withholding taxes like PPh 23 and PPh Final are now grouped together. You will use the SPT Masa PPh Unifikasi for these various withholding obligations.
This unification reduces the number of separate forms you need to file monthly. However, it requires precise classification of each transaction code to ensure accuracy. The OSS system provides additional resources for understanding these classifications.
TAM provides a 360-degree view of your fiscal health under the new regime. It displays a real-time ledger of your debits (obligations) and credits (payments). Under the current DGT compliance forms, this ledger is the definitive record.
It automatically reconciles your payments with your filed returns in real-time. This transparency is a double-edged sword for business owners in Bali. It makes it easier to track your standing, but it also highlights errors instantly.
If your internal books do not match the TAM ledger, you have a problem. Discrepancies can trigger automated flags that lead to compliance inquiries. You can download your data for internal reconciliation purposes regularly.
We recommend doing this monthly to ensure your records align with the DGT’s view. Unfamiliarity with the system is not a valid defense in this new digital era. You must actively monitor your TAM dashboard to stay ahead of potential issues.
Proactive monitoring helps identify discrepancies before they become official problems. The system sends notifications directly to your account for any unresolved matters. Responding promptly to these alerts prevents escalation to formal audits.
A unique feature of Coretax is the “user delegation” or “representation” mechanism. This allows authorized users to act on behalf of the corporate entity. The DGT filing requirements require you to define these roles clearly.
You must assign specific permissions to your directors, accountants, or external consultants. Without these permissions, your tax consultant cannot file for your company. They will not be able to access the specific menus needed for SPT submission.
This security measure ensures that only authorized personnel handle sensitive data. It replaces the old method of simply sharing a generic password with advisors. You must set these permissions up well before the filing deadline.
Waiting until the last minute can result in being locked out of the system. Ensure the user hierarchy in Coretax accurately reflects your current organizational structure. Remove access for former employees immediately to maintain data security.
The system allows for multiple user levels with varying access rights. You can grant view-only access to some staff while reserving filing rights for others. This flexibility helps maintain internal controls while enabling efficient operations.
For Federica, the shift to Coretax wasn’t just a UI update; it was a permission crisis. Managing a boutique export business in Sanur since early 2023, she assumed the old ways worked perfectly. The 46-year-old from Padua, Italy, thought she could simply share her login credentials with her accountant.
This was standard practice in the old DJP Online days, but times have changed dramatically. She didn’t realize that Coretax requires a formal “delegation” setup for all users. Without this formal delegation, her accountant had zero access to her corporate dashboard.
Her filing status remained in limbo just hours before the critical deadline approached. The stress of potentially missing the cutoff was overwhelming for her business. Federica feared the automated penalties that would compound daily if she failed.
Consequently, she engaged a local tax consultant to configure her TAM settings properly. They established the correct user hierarchy, ensuring her compliance remained intact. She now monitors her dashboard monthly to prevent future access issues.
The biggest mistake is assuming legacy systems still apply to current filings. Continuing to use old forms for 2025 will result in invalid submissions. Another error is incomplete data migration during the initial registration process.
Ensure all your NIK and NPWP data is correctly linked in the new profile. Many PT PMA owners overlook the attachment requirements for financial statements. The DGT form rules are strict about the XML structure of these attachments.
Uploading a simple PDF scan is often no longer sufficient for compliance. The system demands structured data that can be analyzed automatically. Ignoring the TAM ledger is a recipe for disaster under the new regime.
If Coretax shows an unpaid balance, the system will calculate interest penalties daily. Do not wait for a physical letter to arrive at your office. The notifications in your digital account are considered official legal notices.
Failing to adapt to the new VAT (PPN) reporting workflow is also common. Ensure your staff understands how e-Faktur integrates with the Coretax reporting menu. Regular training on system updates prevents costly mistakes during filing season.
The Coretax system is designed specifically to enhance audit capabilities. The DGT can now cross-reference data across all tax types instantly. This integrated approach makes discrepancies much easier to identify.
The new system facilitates automated data matching for all submitted returns. Inconsistencies between your VAT and Income Tax returns become easily detectable. For example, your reported revenue in PPh Badan must match your VAT output.
Any variance needs to be explained by valid fiscal reconciliations in your records. The system also monitors your lifestyle and asset data through integration. Integration with other government databases makes it harder to hide wealth.
Audits will likely become more targeted and data-driven in the coming years. Officials will focus on taxpayers with significant ledger discrepancies. This shifts the focus from random checks to risk-based enforcement strategies.
Maintaining accurate, real-time records is your best defense against scrutiny. Proactive compliance is significantly cheaper than retroactive correction after audits. Invest in competent accounting support to navigate this transparent new world.
The Directorate General of Taxes continues to refine the system’s capabilities. Future updates will likely include even more sophisticated analytical tools. Staying informed about these developments is essential for long-term compliance.
