Have you ever felt that managing a restaurant's operations is an emotional rollercoaster?
On one hand, you’re thrilled to see the tables always full and daily revenue climbing.
But on the other hand, a headache instantly kicks in the moment tax reporting season arrives.
For culinary business owners, dealing with taxes is often considered a massive hassle.
Especially if your business already has several branches, tasks like filing your Annual Tax Return (SPT), paying employee income tax (PPh 21), and handling commercial rent taxes can drain a lot of your productive time.
If you’ve been active on social media lately, you’ve probably noticed that netizens and entrepreneurs alike are buzzing about a new term: Coretax DJP.
Many say this new system will make tax reporting much easier, but quite a few are still confused about this new tax filing concept.
As a smart business owner, you certainly don't want to miss out on crucial information directly related to your business's legal compliance.
No need to panic or get confused! In this article, we will thoroughly break down the DJP Coretax tax system using easy-to-understand language.
Let's dive into the complete Coretax guide specifically tailored for you, F&B entrepreneurs, so your tax affairs become seamless and swift!
What is Coretax (Core Tax Administration System)?
Before we go any further, let's get on the same page regarding the basic concept of Coretax.
Simply put, Coretax (Core Tax Administration System) is the latest integrated digital tax system from the Directorate General of Taxes (DJP), designed to automate the entire tax administration process in Indonesia.
This advanced system is also known as the Core Tax Administration System (SIAP) and is regulated under Presidential Regulation Number 40 of 2018.
Officially launched on January 1, 2025, Coretax acts as a "hero" that saves taxpayers from the headache-inducing old systems.
Why is it confusing? Remember the days when you had to open the e-Faktur app to handle supplier invoices, switch to the e-Bupot app for withholding tax, and then log into DJP Online to file your tax return (SPT)? Everything was completely disjointed!
Now, through Coretax, all those scattered applications are unified into a single, integrated web-based portal.
In fact, our Minister of Finance mentioned that this system is designed to resemble a mobile banking app on your smartphone, making paying taxes as easy as topping up your phone credit.
In essence, Coretax is a massive digital transformation step so you no longer need to run back and forth to the Tax Service Office (KPP) just to sort out paperwork.

Key Features of the Coretax Portal for Taxpayers

As a modern system, DJP has injected various advanced features guaranteed to make the workload of your restaurant's finance or HR team much lighter.
Here are some of the flagship features of the Coretax system:
1. Taxpayer Account Management (Integrated Account)
This system provides one main dashboard that displays your entire business tax profile in real-time. Here, you can view your tax rights and obligations, general ledger, and more.
2. Pre-populated Tax Returns and Invoices
Pre-populated means the system will automatically fill in the data on your tax return (SPT) report. Data from e-Faktur (e.g., when you buy raw materials from large suppliers) and e-Bupot will instantly connect to your report. You just need to review it, ensure the numbers match your cash register books, and click confirm.
3. Tax Deposit Account
Coretax now has a feature that functions similarly to a digital wallet (e-wallet). You can deposit a certain amount of funds or top-up a balance into this system. Later, you can use that balance at any time to pay various types of your restaurant's tax bills. It’s highly practical for managing cash flow!
4. One Billing (One Code for All)
Previously, different types of taxes meant different billing codes, forcing you to make multiple transfers. Now, thanks to the One Billing feature, you can pay several different tax obligations at once using just a single billing code. The risk of transferring to the wrong account or using the wrong code drops drastically.
5. AI Chatbot and Top-Tier Security
Aside from its user-friendly design, Coretax is also equipped with an Artificial Intelligence (AI)-based chatbot assistant ready to answer your questions. Plus, your data is guaranteed to be safe because this system is based on cloud computing with advanced encryption to prevent data leaks from cyberattacks.
Access Guide and How to Use the Coretax System for Beginners
Even though the system is advanced, the reality is that many SME players and F&B business owners are still confused about where to start.
One absolute requirement you must complete before accessing this portal is ensuring that your National Identity Number (NIK) has been validated against your Taxpayer Identification Number (NPWP) into the new 16-digit format.
Once the data validation is sorted out, here is how to log into the system:
- For Those Who Already Have a DJP Online Account: You simply enter the Coretax portal, then select the "Forgot Password" (Lupa Kata Sandi) menu to reset your old password. Follow the instructions on the form, then log back in using your ID and the new password.
- For Those With an NPWP But No DJP Online Account: Click the "Activation Request" (Permohonan Aktivasi) menu on the main page. Fill in your personal data and the required business details, then wait until your account is active.
- For New Taxpayers: If your culinary business was just established, you can directly click "Register here" (Daftar di sini) on the main page to create a 16-digit NPWP and gain direct access to Coretax.
After successfully logging in, you will be immediately welcomed by "My Portal" (Portal Saya). From this dashboard, you can directly select menus like "e-Faktur" for supplier matters, or "Payment" (Pembayaran) to settle bills.

F&B Business Tax Reporting Mechanism with the Coretax System
Now, let's discuss the most important part: How is it actually applied to the daily operations of an F&B business?
The culinary business is unique. The cash flow is very fast, there are many raw material suppliers, and it often has more than one branch location.
The arrival of Coretax brings three highly impactful mechanism changes for culinary entrepreneurs, namely:
1. Leave Behind Branch NPWPs, Welcome NITKU
For those of you who have many outlets or franchise branches, you used to be required to manage a Branch NPWP for each location. This obviously gave the administration department a headache.
The good news is, in the Coretax system, Branch NPWPs are officially abolished! In its place, DJP uses the Business Location Identity Number (NITKU).
This means all tax reporting and payment affairs from all your restaurant branches are now centralized and pulled to the Central NPWP. Administration becomes tidy, and it's easy for you to monitor the tax performance of all branches from a single dashboard.
2. Synchronization of Raw Material Purchase Invoice Data
In the culinary business, you definitely frequently buy raw materials from large suppliers (like meat, vegetables, or packaging).
Suppliers who already have the status of Taxable Entrepreneurs (PKP) will issue withholding tax slips or e-Fakturs for your store. With the pre-populated feature in Coretax, invoices from these suppliers automatically enter and are recorded in your account.
However, the challenge is if your restaurant's inventory or cashier recording system is still a mess, you will struggle to match your actual expenditure data with the numbers that automatically appear in Coretax. Transparent synchronization is the key so you don't pay more tax than you should.
3. Manage Restaurant Cash Flow via Tax Deposit
Restaurant operations have many daily tax components, ranging from PPh 21 for barista and chef salaries to building rent tax (PPh Article 4 paragraph 2).
Instead of bothering with different transfers every month, you can allocate part of your busy weekend revenue to the Tax Deposit Account balance in Coretax. When the due date arrives, the system simply deducts your deposit balance automatically. Daily cash flow is safe, and late penalties can be avoided!
FAQ (Frequently Asked Questions)
Still have a few doubts? Here are quick answers to some of the questions most frequently asked by entrepreneurs regarding this new tax system:
1. When is this Coretax system mandatory for entrepreneurs to use?
Coretax was officially launched and has been applicable nationwide since January 1, 2025. This system is gradually replacing the functions of old applications like e-Faktur and e-Bupot.
2. Do I still have to go to the tax office if my restaurant opens a new branch?
Not anymore! All forms of registration for new business locations (NITKU), data updates, to NPWP deletion can now be submitted completely online via the "Data Change" (Perubahan Data) menu in the Coretax Portal.
3. What if the pre-populated feature pulls incorrect supplier invoice data?
Don't worry, this pre-populated data acts as an automatic draft. Before submitting, you still have the right to verify, change, or reject the data if it turns out the numbers do not match your restaurant's bookkeeping receipts.
4. What should I do if the Coretax web is experiencing an error or is hard to log into?
At the beginning of its release, obstacles like errors during profile validation did frequently occur due to the data migration process of millions of residents. However, DJP continues to make improvements. Ensure your internet connection is stable, turn off your VPN (if any), and use the "Forgot Password" feature if your access gets suddenly locked.
CRITICAL WARNING: Input Errors Now Carry Huge Risks!
There is a strict new rule you must pay attention to. Under the old system, if you overpaid or deposited the wrong Income Tax amount (for instance, when filing your Unified Periodic Tax Return or SPT Masa PPh Unifikasi), you could instantly request a correction through a "Book-Entry Transfer" (Pemindahbukuan or Pbk).
Under Coretax, this practice is strictly prohibited!
Any overpayment that has already been submitted in your Periodic Tax Return can no longer be transferred.
Instead, you must go through a lengthy bureaucratic procedure called the Refund of Tax That Should Not Have Been Paid (Pengembalian Pajak yang Seharusnya Tidak Terutang / PPYSTT), which requires an investigation period of up to 3 months before your money is finally refunded.
This means your company's cash flow could be tied up for months simply because of a typo!
Conclusion
So, after dissecting the Coretax system, it’s clear that future administration demands data transparency and neatness, right?
With the pre-populated system pulling data automatically, you can no longer rely on manual bookkeeping.
If there happens to be a recording discrepancy between your internal daily reports and the Coretax data, the consequences can certainly drag on.
