How PER-11/PJ/2025 Changes Tax Invoice Processing Coretax in Indonesia
The implementation of the Coretax system represents a substantial change in Indonesian tax administration. Many foreign business owners in Bali are accustomed to the legacy desktop e-Faktur application for managing Value Added Tax (VAT) obligations. However, this new regulation effectively retires standalone systems and integrates everything into a single web-based platform.
This transition forces a PT PMA in Indonesia to overhaul its daily invoicing workflows to remain compliant. Failure to adapt to these digital protocols exposes your company to administrative sanctions and disrupts your ability to claim input VAT credits effectively.
The specific regulation driving this transformation is PER-11/PJ/2025, which came into effect on 22 May 2025. This regulation fundamentally alters how tax invoices are created, uploaded, and corrected within the Indonesian tax jurisdiction. It introduces stricter validation rules for buyer identities while simultaneously offering a different timeline for upload deadlines.
Understanding how PER-11/PJ/2025 Changes Tax Invoice processing is mandatory for finance teams to ensure operational continuity. The regulation aims to provide legal certainty and full digitalization, but it creates technical risks for the unprepared investor.
Navigating these changes requires a detailed understanding of the new transaction codes and the elimination of manual serial number requests. You must prepare your internal systems to handle the auto-generation of invoice numbers directly through the Coretax portal.
This guide provides a breakdown of the new rules, ensuring your business transitions without triggering warnings. We will explore the practical steps every foreign investor must take to align with the Directorate General of Taxes requirements. Implementing these updates ensures your business operations in Bali continue without fiscal interruptions.

The Shift to Single Coretax Platform in Indonesia
The era of using disjointed applications for tax reporting is officially over under the new framework. The regulation mandates that all VAT invoices must be issued through the unified e-Faktur module within the Coretax system. This replaces the desktop e-Faktur app and the separate VAT Refund for Tourists application used previously.
This unification simplifies software requirements for a PT PMA in Indonesia. You no longer need to maintain local databases or manage backup procedures for desktop application data. Everything is stored centrally on government servers, ensuring real-time data synchronization.
However, this shift means that internet connectivity is now a critical dependency for billing. The regulation explicitly prohibits manual off-system invoices for normal business conditions. Intangible goods and services must also be recorded directly in the system.
A “digital-first” approach now governs how PER-11/PJ/2025 Changes Tax Invoice workflows. Finance teams can no longer draft invoices offline and upload them later in batches without an active internet connection. Real-time connection to the government server is required to generate any valid tax document.
One of the most relieving updates is the removal of the manual Tax Invoice Serial Number (NSFP) request process. Previously, businesses had to request a block of numbers from the tax office and monitor their usage carefully. Running out of numbers often meant a halt in billing operations until a new batch was approved.
Under the Coretax ecosystem, the system automatically assigns a serial number when the invoice is uploaded. This automation eliminates the administrative burden of tracking unused numbers at the end of the year. Your finance team can focus on transaction accuracy rather than number management.
To utilize this feature, a PT PMA in Indonesia only needs a valid Electronic Certificate (Sertel) and an Authorization Code. These credentials authenticate your company identity within the Coretax portal. Ensuring your Sertel remains active is now the primary prerequisite for invoicing.
This change reduces the risk of human error in numbering sequences. In the past, skipping a number or reusing one could trigger a compliance warning. The automated system ensures perfectly sequential issuance compliant with regulations.
The regulation introduces an adjustment to the timeline for uploading electronic tax invoices. The deadline has been extended from the 15th to the 20th of the following month. This extension provides additional time for businesses with high transaction volumes to finalize their records.
This five-day extension aligns the upload deadline with the monthly tax payment deadline. It simplifies the monthly closing calendar for accountants working for a company in Bali. You now have a unified target date for both finalizing invoices and preparing the tax payment.
However, this new deadline is firm and strictly enforced by the system. Uploading an invoice after the 20th will likely result in the rejection of the document by the portal. The system’s ability to lock out late uploads is much more effective than in previous versions.
New deadlines are a core part of how PER-11/PJ/2025 Changes Tax Invoice processing for better legal certainty. If you upload by the 20th, you have a strong legal basis to avoid late-upload disputes in audits. This clarity is a major improvement for businesses operating across the archipelago.
A subtle but impactful change is the introduction of the new transaction code “10”. This code is specifically designated for “other supplies” where VAT is collected by the seller. Previously, these transactions were often grouped under code 06, leading to classification errors.
For a PT PMA in Indonesia, this means you must review your product and service mapping. If your business engages in transactions that fall into this residual category, you must update your accounting software. Using the old code 06 for these supplies will cause validation errors in the Coretax module.
This change aims to improve the classification of taxable supplies in the national database. It allows the tax authority to distinguish between specific special schemes and general supplies more effectively. Accurate coding is essential to avoid questions during automated compliance checks.
Finance managers must train their staff on when to apply code 10 versus other codes. Misclassification remains a common trigger for tax office inquiries. The way PER-11/PJ/2025 Changes Tax Invoice coding structures demands precision during the initial data entry phase.
The government recognizes that shifting to Coretax is a complex process for businesses. To ease this transition, the regulation offers specific relaxations for the January to March 2025 period. During this window, invoices printed or saved as PDFs that miss certain fields are still considered valid.
This is critical for companies that may struggle to update their invoice templates immediately. As long as the missing information exists in the government system, the invoice remains compliant. This prevents operational bottlenecks during the early months of adoption.
Importantly, the input VAT on these invoices remains creditable for the buyer. This protects your B2B clients from losing their tax credits due to your administrative delays. It maintains commercial trust while software systems are being upgraded.
However, this relaxation is strictly limited to the first quarter of 2025. From April onwards, the way PER-11/PJ/2025 Changes Tax Invoice rules applies becomes strict. Incomplete invoices issued after March will be subject to standard sanctions and potential rejection.
The regulation significantly tightens the rules regarding errors in buyer identity. If you issue an invoice with the wrong NPWP or NIK, you can no longer simply issue a “replacement invoice”. The new rule mandates that you must cancel the incorrect invoice entirely.
After cancellation, you must create a completely new invoice with the correct identity details. This change aims to prevent irregular accounting practices often seen in the past. It forces businesses to verify the buyer’s tax details before the document is generated.
Replacement invoices are still permitted for other types of errors, such as price adjustments. However, these replacements must now explicitly reference any notes of return or cancellation. The system links the replacement directly to the net value calculation.
This stricter control ensures that auditors have a clear and linear history of transaction corrections. For a PT PMA in Indonesia, this means your customer database must be accurate before you bill. Validation occurs in real-time within the Coretax interface.
Meet Lars, a 42-year-old Swedish national who owns a high-end furniture export business in Seminyak. His company, a registered PT PMA, had used the old desktop e-Faktur application for five years without issue. When the Coretax transition began, Lars assumed his finance staff could continue using the same correction methods.
In late May 2025, his finance manager attempted to issue a replacement invoice for a client who had provided the wrong NPWP. Under the old rules, this was a simple fix. However, the Coretax system repeatedly rejected the replacement due to the new PER-11/PJ/2025 protocols regarding identity errors. Storage fees at the port began to accumulate while the team struggled with the system.
The shipment was stuck because the commercial invoice did not match the tax documents held by customs. Lars realized his team had not updated their internal procedures to reflect the “cancel and reissue” mandate. He contacted Balivisa.co for urgent consultation on the new regulations.
The team guided his staff to cancel the erroneous invoice and generate a new one with a fresh serial number. They also helped update the customer database to prevent future errors. The cargo was released three days later, and Lars immediately retrained his team on the new Coretax workflows.
To manage this transition, you must prioritize the validity of your digital credentials. Ensure your Electronic Certificate is active and accessible to your finance team. Without this, your access to the Coretax e-Faktur module is completely blocked.
You should also conduct an audit of your product codes. Ensure that any transaction falling under the new code 10 is correctly mapped in your internal systems. Relying on default codes from previous years will lead to immediate compliance flags.
Internal controls must be established to monitor the 20th-of-the-month deadline. Do not leave uploads until the last minute, as server traffic may be high. Implement a policy to finalize all uploads by the 18th to ensure compliance.
Finally, educate your B2B clients about the changes. Explain that you cannot issue replacement invoices for identity errors and request their updated tax details upfront. Clear communication prevents disputes and payment delays in Indonesia.
No. The regulation mandates the use of the web-based Coretax e-Faktur module for all invoices.
The system will reject it, and you will face late reporting penalties and potential audit scrutiny.
You must cancel the existing invoice and issue a new one. Replacement invoices are not allowed for identity errors.
Yes. Coretax automatically assigns the serial number when you upload and approve the invoice.
Yes. All supplies, including intangible goods and services, must use the Coretax e-Faktur system.
