Synchronizing Coretax and OSS 2026 is very practical and easy. You just need to log in to your company’s OSS RBA account. After that, go to the profile menu and click the tax synchronization button. The system will automatically pull data from the latest Coretax portal.
Make sure your Population Identification Number or NPWP is valid. This process ensures that your business license is not blocked by the government.
Let’s discuss the technical steps in more detail!
Complete Guide to Coretax and OSS 2026 Synchronization
The government continues to update the country’s administrative system every year. In 2026, the Directorate General of Taxes launched the Coretax system. This advanced system replaces the old tax application. Therefore, tax data must be connected to licensing. The licensing system is called Risk-Based OSS which aims to prevent tax evasion of entrepreneurs.
Here is a step-by-step guide that you must follow:
A. Mandatory Preparation Before Starting the Process
You can’t just press the synchronization button. There are several important things that you must prepare beforehand. First, make sure the company tax account is active in Coretax. You must first match the NIK to a personal NPWP.
Second, prepare the password for the company’s OSS RBA account. Also, make sure that the office internet connection is stable and smooth. System failures often occur due to sudden connection drops. Careful preparation will definitely speed up the process of merging valuable data.

B. Technical Steps for Linking Company Accounts
Let’s get into the execution stage of data pooling. First, open the official OSS RBA website via a browser. Then, log in using your company account access rights. Once the main page opens, look for the company profile menu.
Next, scroll down the screen to the bottom of the profile. You will find a special button for linking tax data. Click the button and wait for the system to process your request. The OSS system will communicate directly with the Coretax system server.
C. Verification of Tax Data Conformity
The system does not immediately approve the data union request. The screen will display the details of your company’s tax data. You must check the correctness of the data very carefully. Make sure the company name and address match the official documents.
Also check the correctness of the company’s tax identity number. If there is incorrect data, you must correct it immediately. You can correct the data through the Coretax portal directly. Never agree to the withdrawal of erroneous or false data.
D. Overcoming Data Unification Failure Obstacles
Sometimes, the data withdrawal process experiences temporary technical failures. You don’t need to panic if you see this failure notification. The cause of the failure is usually due to a difference in the format in which the name is written. Or, the government server is undergoing routine network repairs.
The first step is to try repeating the process a few hours later. Also clear your browser’s history or cache. If it still fails, contact the official state government helpline. You can call the tax officer’s official contact service.

The Great Benefits of Integrated Administration
The unification of this system provides many conveniences for obedient entrepreneurs. You no longer need to upload tax documents manually. The OSS system will automatically read your company’s tax compliance level. This greatly speeds up the process of applying for a new business license.
You can participate in government project tenders with peace of mind. Your company will be listed as a credible business entity. This good reputation will surely attract many investors. Administrative compliance always brings blessings to the growth of business operations.
What happens if you don’t activate Coretax?
KH Friend, ignoring the activation of this new tax system is very dangerous. The government will restrict all access to your company’s tax administration services. You will not be able to issue tax invoices for client transactions. This will certainly paralyze the company’s cash inflow. Clients will refuse to pay without an official invoice document.
In addition, the OSS system cannot pull compliance data. As a result, the government has the right to freeze your Business Identification Number. The company also has the potential to receive penalties for late reporting of tax periods. These cumulative sanctions are sure to destroy a business’s reputation and finances. Therefore, activate your Coretax account immediately without delay.
FAQs About Coretax Data Unification
KH friends, the new administration system must have raised many questions. Let’s discuss the various technical obstacles that often occur.
Q: Is the data unification process subject to an official fee?
A: The data unification process is completely free of charge. The government provides this digital administration service free of charge. You only need a computer device and a stable internet network. Never trust anyone who asks for payment for this process. Illegal levies are pure fraud.
Q: What if the company is in arrears with annual tax payments?
A: The Coretax system will record your company’s tax arrears status. This poor compliance data will flow directly to the OSS system. As a result, the OSS system will delay the issuance of a new business license. You must pay off the tax arrears first. Once paid, the compliance status in OSS will return to green.
Q: How long does this data unification take?
A: The system withdrawal process is usually very fast. You only need to wait a few seconds to minutes. The computer system works in real time. However, it may take longer if the server is full. Make sure you do this during off-peak hours.
Q: Does the managing director have to do this process himself?
A: The managing director can delegate this task to administrative staff. However, the staff must have company account access rights. Ensure that the administrative staff understands how to use the OSS system. The managing director still bears full responsibility for the correctness of the data. Internal supervision is essential to avoid fatal errors.
Q: Is company data safe from cyber hackers?
A: The government has equipped the Coretax system with very tight security. Your company data is stored on official state-owned servers. The system uses secure high-level encryption technology. However, you must also keep your account password confidential. Never share the password with any outside party.
