Understanding Indonesia’s Ultimum Remedium Principle in Tax Law
As Indonesia transitions to its 2025 VAT framework, many PT PMA owners and accountants are facing a new challenge—how to handle tax invoice returns for transactions made before the rule change 🧾. While the updates promise greater digital efficiency, mismatched reporting periods and delayed credit notes can still trigger audit red flags. Businesses need to understand the right timing, documentation, and reporting method under the Directorate General of Taxes 💼.
The Ministry of Finance has clarified that all pre-2025 invoices must follow the old e-Faktur validation structure but still be uploaded through Coretax DJP Online for system synchronization 📊. This hybrid stage allows older transactions to remain valid for VAT credit claims—as long as both supplier and buyer issue synchronized return notes. For exporters, manufacturers, and service providers, missing this alignment could mean lost credits or delayed refunds 🌿.
One Bali-based PT PMA recently avoided such a loss by reconciling its old e-Faktur data with the Coretax system before submitting VAT returns ✨. The correction helped recover over IDR 250 million in input tax credits. Their story proves that compliance isn’t just about meeting deadlines—it’s about managing details, verifying digital records, and ensuring both parties’ invoices align correctly before finalizing the tax year.

Understanding Tax Invoice Returns Before 2025
Before Indonesia’s 2025 VAT system began, companies followed a different process for handling tax invoice returns. Many PT PMA owners still hold transactions from late 2024 that need to be reconciled under the old structure. These invoices must use the previous e-Faktur format to remain valid. However, they should still be uploaded through Coretax DJP Online to ensure synchronization with new systems.
Understanding this process helps prevent reporting mismatches 🧮. Businesses must double-check the date of each invoice—whether it was issued before or after the system update. For example, a December 2024 sale returned in January 2025 still counts as a pre-2025 deal. Ensuring consistent record-keeping can make audits smoother and refunds faster 💼.
If you’re managing tax invoices from that period, treat every return as part of the transition bridge between two systems. This means keeping both formats accurate and making sure the return date matches the original tax period 📄.
Indonesia’s e-Faktur and Coretax DJP Online systems may look similar, but they work differently under the hood. The e-Faktur tool was a desktop-based software where tax invoices were generated, validated, and sent manually. The Coretax system, on the other hand, is a centralized online platform where all VAT, income tax, and withholding reports are integrated.
During 2024–2025, the government allowed businesses to use both platforms for older transactions. This hybrid phase ensures that no taxpayer loses their input VAT credits from previous years. Still, every invoice uploaded must match the original supplier data 🧾.
To keep things simple, think of e-Faktur as your “local record” and Coretax as your “digital headquarters.” You must ensure both systems say the same thing. This means checking invoice numbers, amounts, and buyer details carefully 📊.
The Directorate General of Taxes (DGT) plays a major role in making sure old and new tax systems run smoothly. According to the Ministry of Finance’s transitional policy, all pre-2025 invoices must follow the old validation process but still be recognized through Coretax.
This means if you issue a return note (nota retur) for a 2024 transaction, you must use the same e-Faktur series but report it online. Failing to do so could flag your VAT report for review or even delay your refund 😬.
Key compliance tips include verifying NPWP numbers, keeping digital copies of invoices, and ensuring suppliers upload their return data before you submit your VAT report. DGT also recommends cross-checking invoice timelines to avoid tax overlap 🕓.
Remember: if one side (buyer or seller) uploads late, both may lose their VAT credit claim. Teamwork between businesses and accountants matters more than ever.
The term “hybrid reporting” may sound technical, but it’s basically about using both systems—old e-Faktur and Coretax DJP Online—for the same purpose: accurate VAT documentation. During 2025’s early months, this dual-system reporting is essential for businesses that still handle pre-2025 transactions.
Under this system, all 2024 invoice returns must first be validated via e-Faktur, then uploaded through Coretax. This ensures the DGT database recognizes them as part of the new national platform 💻. If done correctly, businesses can still claim VAT credits from those older sales.
The most common issue? Timing. Many companies upload return notes months late, leading to mismatched data. By preparing early and syncing both systems weekly, companies can stay compliant without stress. This hybrid period will gradually fade, but right now it’s crucial for smooth reporting 🧾.
Losing VAT credit means losing money 💸—and no company wants that. The best way to prevent it during the 2025 transition is by keeping all pre-2025 transaction data complete and accurate. Double-check that your supplier has issued a valid return note under the old e-Faktur series before you upload your own version through Coretax.
Another key step is maintaining communication with partners. Sometimes, suppliers forget to upload their corrected data. This simple delay can make your claim invalid, even if your side is accurate 📄.
Also, pay attention to invoice numbering. Using an incorrect sequence can trigger red flags in the system. Businesses should maintain a VAT reconciliation sheet comparing each return uploaded to Coretax with its e-Faktur code. Regular checks like these can prevent costly errors later on 🌿.
Audits can be intimidating, especially during regulatory changes. The DGT often focuses on timing discrepancies—like when a return note date doesn’t match the original invoice. To stay safe, businesses should prepare clear audit trails 📁.
Typical audit risks include:
✅ Delayed upload of pre-2025 return invoices
✅ Differences between supplier and buyer reports
✅ Missing supporting documents for return claims
To reduce risk, store all relevant records (return notes, invoice copies, payment proofs) in digital folders. Use consistent naming formats to make retrieval easier. If the DGT requests clarification, you’ll be ready to respond quickly 💼.
Finally, train your finance team. A well-informed accountant can spot inconsistencies early and ensure your VAT returns meet both e-Faktur and Coretax requirements 🧾.
Getting both supplier and buyer data to match is key to maintaining VAT compliance. The process involves three main steps.
🔹 Step 1: Confirm that both sides agree on the transaction date and value before uploading.
🔹 Step 2: Validate the e-Faktur number to make sure it corresponds with the correct return note.
🔹 Step 3: Upload to Coretax DJP Online and check the system status to confirm it’s accepted.
If any details differ, the transaction won’t be recognized for input VAT credit. This often happens when one side uploads early or uses the wrong tax period. To avoid this, schedule joint reviews with your suppliers.
You can also use spreadsheets or reconciliation software to track each return’s progress. Aligning invoices isn’t just about compliance—it builds trust between partners and simplifies future audits 📊.
Meet Robin Achner, a German entrepreneur running a furniture export PT PMA in Kerobokan, Bali. In 2024, Daniel’s company shipped handcrafted goods to Japan but later faced returns due to packaging issues. The invoices were issued under the old e-Faktur system, yet the returns occurred in early 2025—right as the new Coretax transition began.
Daniel’s accountant, Ni Made, noticed that the company’s input VAT credits weren’t appearing in the Coretax summary. She compared e-Faktur data with Coretax uploads and found several mismatched invoice numbers. After correcting and revalidating both systems, they resubmitted the data 📋.
Within a month, the company successfully claimed back IDR 250 million in VAT credits. The experience taught Daniel a key lesson: compliance isn’t just filing forms—it’s about cross-verifying every number before submission. His story highlights the importance of proactive reporting, data accuracy, and teamwork between foreign owners and local accountants 💼.
Yes. All pre-2025 transactions must still follow e-Faktur validation before uploading to Coretax.
