Indonesia transitions from e-Faktur to Coretax e-invoice clearance mandate
Indonesia’s Directorate General of Taxes (DJP) is entering the final phase of a major overhaul of its VAT compliance infrastructure. By 31 December 2025, the long-standing e-Faktur electronic invoicing system will be formally replaced by Coretax, a centralised digital tax platform that introduces a stricter, real-time VAT invoice clearance model for almost all VAT-registered businesses (Pengusaha Kena Pajak – PKP).
Following an initial rollout in early 2025, the DJP has confirmed that Coretax will become fully enforceable nationwide, marking a significant escalation in Indonesia’s digital tax control strategy.
From e-Faktur to Coretax: what has changed?
Indonesia was an early adopter of clearance-style VAT invoicing. The e-Faktur system, introduced in 2015 and completed in 2016, already required tax authority validation and QR-coded invoices. However, Coretax goes substantially further by consolidating invoicing, validation, and reporting into a single, mandatory platform with real-time controls.
Under Coretax, VAT invoices are no longer merely registered post-creation. Instead, clearance becomes a legal precondition for invoice issuance. An invoice that has not been successfully validated by Coretax is not recognised for VAT purposes and cannot support input tax recovery.
Scope of the Coretax mandate
The Coretax obligation applies broadly and consistently across transaction types:
-
Domestic B2B and B2G taxable supplies
-
Export invoices
-
Corrective documents, including credit notes and debit notes
With limited exceptions, all PKP taxpayers are required to issue VAT invoices through Coretax, making it a near-universal mandate rather than a phased or sector-specific obligation.
Clearance-based invoicing workflow
Coretax introduces a structured clearance process that must be followed for every VAT invoice:
-
Invoice creation
Invoice data must be generated in the prescribed local XML format, either via the Coretax web portal or approved technical channels.
-
Submission and validation
The XML file is uploaded to Coretax, where the DJP validates the invoice content in real time.
-
Authorisation
Once validated, Coretax assigns:
-
A Tax Invoice Serial Number (NSFP)
-
A QR code confirming approval
-
-
Legal issuance
Only after these elements are assigned can the invoice be issued to the customer. Invoices lacking clearance are invalid for VAT deduction purposes.
This model reinforces Indonesia’s move towards transactional-level VAT control, reducing reliance on post-audit enforcement.
Channels for invoice submission
While Coretax is a single platform, the DJP continues to allow multiple technical access routes:
-
Web portal – mandatory for most small and medium-sized taxpayers
-
Desktop client – retained for certain operational use cases
-
Host-to-Host (H2H) integration – available for high-volume and enterprise taxpayers, enabling direct ERP connectivity
The continued availability of H2H integration is critical for businesses issuing large volumes of invoices or operating complex supply chains.
Compliance timing and enforcement
The DJP has confirmed that full enforcement applies by 31 December 2025. From that point onward:
-
Invoices must be successfully cleared by Coretax within the statutory issuance deadline
-
Non-cleared invoices will not be recognised for VAT purposes
-
Buyers will be unable to deduct input VAT unless the supplier’s invoice has been validated by Coretax
This places increased operational pressure on invoice generation, system uptime, and data accuracy.
