OSS stands for Online Single Submission. It is Indonesia’s government-run digital system for business registration and licensing. Through OSS, a company obtains its business identification number, applies for permits, and confirms the activities it is legally allowed to conduct.

In 2026, OSS is no longer just a website for registering a company. It is the system through which the government sees the structure of the business: permitted activities, address, risk level, investment plan, licenses, tax data, and the company’s ongoing compliance obligations.

An error in OSS may lead to a situation where the company is formally registered, but cannot operate legally, safely, or efficiently in practice.

OSS is Indonesia’s government online system for business registration and licensing. Through OSS, a company obtains its core documents, applies for permits, and manages part of its ongoing business compliance.

NIB is the main business identification number in Indonesia. A company obtains it through OSS. However, NIB by itself does not give the company the right to conduct any business activity it wants.

For simple activities, NIB may be sufficient. For many other business models, additional documents may be required, such as certificates, approvals, PB UMKU, or separate licenses.
As of 2026, OSS operates under the new rules of PP 28/2025. PP means Government Regulation of Indonesia. This regulation replaced the previous framework under PP 5/2021.
Since December 2025, Indonesia has also used the new KBLI 2025 classification. KBLI is the official list of business activity codes in Indonesia. It is how the government identifies what a company actually does.

If a company is registered under an old code, or if its actual business activity does not match the new KBLI, the company data must be reviewed and brought into compliance by 18 June 2026.

OSS stands for Online Single Submission. It is Indonesia’s central government online system for business registration and business licensing.

Through OSS, a company obtains its main registration and licensing documents. For PT PMA companies, this system is especially important because it records:

• the company’s business activity;
• KBLI;
• NIB;
• business address;
• business risk level;
• licensing requirements;
• investment structure;
• data that may later be used by other government systems.

After the reform under PP 28/2025, OSS is integrated with the tax system and the Ministry of Investment.
In practical terms, OSS is the system through which the government understands what a company does and whether its activity meets the applicable requirements.

NIB stands for Nomor Induk Berusaha, or Business Identification Number.

It is the company’s main number in the OSS system. It combines several registration functions and allows the company to move further through the system: apply for permits, open a corporate bank account, confirm its business activity, and interact with government institutions.

However, NIB is an entry point into the system, not a universal permit for any business activity.
If a company has received an NIB, this does not automatically mean that it can immediately operate in full. Everything depends on the selected KBLI, the risk level, and the additional requirements that apply to the specific business activity.

In 2026, OSS works as a business control system.

It records not only the fact that a company has been registered, but the entire structure of the company’s activity:

• which KBLI was selected;
• where the business is located;
• what risk level applies to the activity;
• which licenses are required;
• what investment structure was declared;
• whether the company meets PT PMA requirements;
• what obligations arise after registration.

Therefore, it is not enough to simply open a PT PMA, receive an NIB, and assume that the legal part is complete.
In practice, NIB is only the beginning. After receiving it, the company must understand which permits are required, how reporting must be submitted, and which data must match across OSS, the tax system, and corporate documents.

KBLI is the official business activity code of a company. It tells the government what exactly the business does.

Since December 2025, Indonesia has used KBLI 2025 under BPS Regulation No. 7/2025. The new classification contains 1,559 codes instead of 1,789.
This means that some old codes disappeared, while others were changed or split into new codes. For example, KBLI 6312 was completely abolished.

If a company was registered before December 2025, it is necessary to check:

• whether the old KBLI is still valid;
• whether it was abolished;
• whether the business activity description changed;
• whether the actual business corresponds to the new classification;
• whether the OSS data needs to be updated.

The KBLI update deadline is 18 June 2026.
If the code is not checked in advance, the problem may not appear immediately. Such issues often surface later: during a bank compliance review, corporate data amendment, visa extension, OSS review, or scheduled inspection.

PT PMA stands for Perseroan Terbatas Penanaman Modal Asing, an Indonesian limited liability company with foreign investment.

Under Article 212 of PP 28/2025, for foreign investment / PMA, the minimum investment must be more than IDR 10 billion, excluding land and buildings, for each 5-digit KBLI and for each business location.

This means that a company cannot simply open a PT PMA, add several KBLI codes, and present one general investment plan for all activities.

OSS looks at the structure in more detail:

• which exact KBLI was selected;
• how many locations the business has;
• where the activity is conducted;
• what investment is declared for each activity;
• whether the structure complies with PP 28/2025.

However, there are exceptions. Article 212 of PP 28/2025 provides special rules for certain sectors, including:

• wholesale trade;
• food and beverages;
• construction;
• manufacturing within one production line involving different 5-digit KBLI codes.

For these sectors, the calculation may not strictly follow the formula “each 5-digit KBLI × each location.” Instead, the special logic stated in the regulation may apply.
Therefore, the investment plan must be reviewed based on the specific KBLI, location, and business model.

OSS operates under a risk-based approach.

RBA means Risk-Based Approach. This means that the company’s requirements depend on how risky the government considers the specific activity to be.
After PP 28/2025, the number of PB UMKU permits was reduced from 1,006 to 357.

PB UMKU refers to additional permits that support business activities.
The general logic remains the same: the higher the risk of the activity, the more requirements apply to the company.

A common mistake is choosing an “easier” KBLI in order to fall into a lower risk category and receive NIB faster. In practice, this only creates delayed problems and increases the overall risk for the business.

Before filing in OSS, it is necessary to review not just one document, but the entire business structure.

The address can no longer be treated as a formality. OSS must show the real address of the business activity, and this address must match the selected KBLI and zoning rules.

For Bali, this is especially important because the same business may be allowed in one zone and problematic in another. For villa rental, coworking, tourist accommodation, trade, or restaurant business, it is necessary to check not only the KBLI, but also the location.

If the address does not match the activity, the problem may appear:

• during registration;
• when updating NIB;
• during licensing;
• during an OSS review;
• when opening a bank account;
• when changing corporate data.

In practical terms, if the address does not meet the requirements and restrictions for the specific activity, the entire structure may become problematic.

The main problem with OSS is not that the system is complicated.

The main problem is that an error in OSS rarely stays within one document. It may affect the entire company structure.

Incorrect data in OSS may affect:

• NIB;
• licensing;
• PB UMKU;
• LKPM;
• tax data;
• corporate bank account;
• Investor KITAS;
• Director KITAS;
• amendments to corporate documents;
• company operations after registration.

If the data in OSS does not match the company’s actual business activity, the problem may appear later: during bank compliance review, tax review, immigration procedures, licensing, or the first inspection.

In other words, an OSS mistake may cost not just one form, but the entire business structure.

Sunrise Business does not begin the process by filing in OSS. We first review how the business model is structured and whether it fits the system requirements.

To do this, we need to understand:

• what exactly the company will do;
• which KBLI corresponds to the actual activity;
• whether the code is valid under KBLI 2025;
• whether the old code has been abolished;
• what risk level applies to the activity;
• which permits are required after NIB;
• whether the address matches RDTR zoning;
• whether the data in Akta, OSS, and NPWP is consistent;
• whether the investment threshold has been calculated correctly;
• what obligations will arise after registration;
• whether there are risks for Investor KITAS or Director KITAS.

After the review, it becomes clear what must be corrected before filing, updating data, or reaching the 18 June 2026 deadline.

Contact Sunrise Business.
We first analyze your business model, then check the KBLI, NIB, address, RDTR, investment threshold, risk level, licenses, Akta, NPWP, and post-registration obligations.

If you already have a company, we can help determine whether its OSS profile corresponds to KBLI 2025 and which discrepancies should be corrected before 18 June 2026.

This helps you avoid spending money on a structure that exists on paper, but may later create problems with banks, licensing, visas, reporting, or inspections.
