Coretax and Legacy Tax Systems: Indonesia’s Strategy for 2025 Stability
The debate over Indonesia’s 2025 tax direction is heating up as businesses prepare for tighter digital oversight and fewer “loophole” days. With Coretax taking center stage and legacy platforms still hanging on for stability, many PT PMA owners feel the system is becoming more complex than ever 😅. There’s real concern among foreign investors about whether this transition will create room for tax errors, late filings, or even unexpected penalties — especially when rules shift faster than most teams can adapt.
But here’s the good news. The government isn’t abandoning familiar systems like e-Billing or e-Faktur immediately — instead, they’re combining both Coretax and existing tools to keep the transition manageable for business taxpayers ✅. Officials from the Directorate General of Taxes have confirmed that a phased approach is in motion, ensuring smoother tax filing without forcing companies to overhaul their processes overnight. That means PT PMA owners in Bali and Jakarta still have time to adjust, train their teams, and upgrade systems without feeling rushed.
Meanwhile, Indonesia’s broader fiscal targets for 2025 are being coordinated through policy roadmaps led by the Ministry of Finance, signaling that tax digitalization will play a major role in stabilizing state revenue 📊. Some tax consultants have already tested the new Coretax flow and report that filing monthly VAT and withholding tax feels more structured and automated 🤖. They’ve seen fewer errors in the dashboard and faster updates on payment status — a promising sign for companies that rely on precise reporting.
If you’re running a global-minded business in Indonesia, now is the moment to stay one step ahead by blending old habits with the new digital workflow before Coretax becomes the only option. And yes — the sooner you get your staff trained, the smoother 2025 will feel ⚙️. Strategic updates shared by Bank Indonesia also hint that stronger digital tax infrastructure will support macroeconomic stability, making this shift not just a tax issue, but a national growth priority.

Why Indonesia Needs Both Coretax and Legacy Tools in 2025 ⚙️
Indonesia is making big moves toward a more digital future for its tax system, but that doesn’t mean the old tools are going away just yet. Coretax is the new engine that powers online reporting, offering more automatic features and fewer manual errors than legacy tools. But for 2025, both systems will still work side by side to help foreign-owned PT PMA companies adjust smoothly 🛠️. Businesses that rely on older software like e-Faktur or e-Billing can still use them during the transition period.
Keeping both systems running at the same time helps prevent sudden disruptions in tax payments or filings, especially for companies that haven’t fully switched to Coretax yet. It also reduces the pressure on teams who need time to train and update their workflows. This dual system might sound complicated, but it’s actually meant to prevent panic — not create it 😅.
Coretax gives business owners more control and visibility over monthly filings, payments, and document history. PT PMA owners can submit VAT, income tax, or withholding tax reports in a single login, making life easier and faster 🖥️. The new dashboard lets you see status updates in real time, and even shows if your payment code is about to expire — which helps avoid late fees.
Plus, Coretax is designed to reduce errors. When you enter numbers or choose a tax type, the system can auto-fill or validate fields to prevent wrong submissions. This means fewer mistakes, fewer penalties, and less stress for your accountant ✅. And in the long run, Coretax improves the government’s overall tax data accuracy — something both businesses and the country benefit from.
Even if you’re using Coretax, you’ll still generate payment codes (ID Billing) using e-Billing for now. First, log into the Coretax dashboard and select the type of tax you want to file. The system will walk you through filling out your report, and once it’s done, it’ll prompt you to create an ID Billing code.
Then, switch over to the e-Billing page, enter the code, and make your payment using online banking or an approved payment channel 💸. The process may sound like extra work, but it still saves time compared to manual bookkeeping and bank visits. Once the transition is complete, Coretax will fully handle both submission and payment — but for now, both tools are still part of the journey.
PT PMA owners in Indonesia should start preparing for the shift to Coretax by updating internal systems and team training. You’ll need to make sure your tax officer or finance team knows how to use Coretax and e-Billing together, especially for monthly tax workflows. It’s also smart to review your tax calendar and keep backups of all previous tax files before making the jump ⚙️.
In 2025, some tax forms may be retired and replaced by Coretax-only formats. That means staying updated with tax announcements, especially if you work in sectors like hospitality, digital business, or manufacturing. Set up clear roles and access rights for your team members, and start organizing everything digitally — Coretax loves clean data more than paper stacks 🗂️.
Ignoring Coretax during 2025 might not cause immediate penalties, but it will create problems in the future. If you stick only to old systems, you could miss important deadlines, fail to upload the right forms, or lose access to tax payment history. That could lead to tax disputes, audits, or even fines 😬.
Another risk is data mismatch. If your e-Billing, e-Faktur, and Coretax records don’t match, the system will flag you for potential investigation. And since Coretax is becoming the main hub for tax oversight, companies that refuse to adapt now may find themselves scrambling when legacy systems finally shut down. Better to take small steps early than panic later!
Some monthly and annual forms will still use the old systems until Coretax fully replaces them. For example, most VAT (PPN) reports and invoice uploads use e-Faktur, while payment codes for PPh21 and PPh23 still require e-Billing. Meanwhile, Coretax handles tax form submissions but uses legacy platforms for payment and invoice processing.
This hybrid setup allows companies more time to adapt without shutting down existing workflows. The Ministry of Finance has confirmed that the full switch will happen gradually, not overnight. So for now, keep checking which parts of tax reporting are Coretax-ready — and which ones aren’t quite there yet 🔄.
Meet Daniel, a 41-year-old entrepreneur from Australia who runs a PT PMA cafe in Canggu. In 2024, his accountant still used e-Faktur and e-Billing for all filing. But once Coretax started rolling out, Daniel’s finance team got confused — which system should they use? Why are there two dashboards? Where do you upload documents?
To fix the confusion, Daniel hired a tax consultant in Denpasar. Together, they switched monthly PPh reports to Coretax while keeping VAT in e-Faktur. They created a checklist of filing steps and taught the accountant how to match ID Billing codes with Coretax submissions. The result? No missed deadlines, fewer mistakes, and a happier tax office 👍.
Daniel’s story shows that mixing old and new systems isn’t the problem — not knowing how to sync them is. With the right plan, Coretax can make filing easier, not harder.
Coretax won’t fully replace legacy systems in 2025, but it will take over most tax functions by 2026–2027. The government is giving companies enough time to migrate without disruption. That means PT PMA owners still have time to test the platform, update staff skills, and shift tax files into a cleaner digital workflow.
Legacy tools like e-Faktur and e-Billing will still run but may stop being updated or supported sooner than expected. So the question isn’t whether you should use Coretax — but how soon you’ll make it part of your business strategy 📈.
Yes, for now. Coretax handles reporting, but e-Billing still generates payment codes.
Not recommended. The sooner you adapt, the less stressful 2025 will be.
Real-time tracking and fewer filing errors.
It helps. Your accountant or tax officer should get familiar with the new interface.
Yes, likely before 2027, once full integration is completed.
