How to Register Changes in a Polish Company?

Q: How to change company details in Poland?

To change company details in Poland, any corporate modifications must comply with applicable laws and be registered with the National Court Register (KRS). This application process must be handled exclusively in an electronic format via official online portals, ensuring that the company's public registry data remains accurate and legally binding for third parties.

Q: When Is KRS Registration Required?

KRS registration is required for both declaratory entries, which merely confirm corporate changes that have already taken place (such as board or address updates), and constitutive entries, which only become legally effective once registered (such as name changes or share capital amendments). Understanding this distinction is critical for company management, as it determines exactly when a specific corporate modification becomes legally binding.

Q: How to register company changes with the KRS business register?

To register company changes, you must submit an electronic application along with required supporting documents and fee payments (PLN 300–350) to the relevant registry court via the Court Registers Portal or the S24 platform. This mandatory online process requires a qualified electronic signature or trusted profile, and it typically takes several weeks to months for the court to fully process the update.

How to change company details in Poland?

Running a business in Poland often presents foreign investors with various challenges, but also offers numerous benefits. As a member of the European Union, Poland provides not only a stable legal and economic environment, but also broad access to the European market. However, a dynamically changing business environment may require a company to adapt its operations to new circumstances.

In the course of a company’s operations, the company’s management board or shareholders may need to implement changes, such as recapitalising the company by increasing its share capital, changing the ownership structure, changing the registered office or reorganising the management bodies. Sometimes these decisions are driven by a change in strategy, while in other cases they result from market or regulatory requirements.

Any change in a company must comply with applicable laws and take into account the relevant registration procedures before the National Court Register (KRS). The KRS functions as a nationwide database and a Polish business register and plays a key role in the Polish legal system, as its entries are subject to the presumption of accuracy.

The National Court Register (KRS) functions as a central, nationwide database that plays an essential role in Poland's commercial framework. Crucially, all data published in this register is legally subject to a strict presumption of accuracy.

This means that the data contained in the register is binding on third parties. For this reason, ensuring that entries remain up to date is of great importance for the transparency and security of commercial transactions.

In this article, we focus on the key aspects of changes in companies with share capital, such as limited liability companies (sp. z o.o.) and joint-stock companies (S.A.), as well as the process of registering such changes with the KRS.

Changes in a Polish Company: When is KRS Registration Required?

Changes in companies with share capital can be classified according to their legal effects and the moment at which they become effective. There are two types of entries in the National Court Register: declaratory and constitutive.

Declaratory Entries in the KRS

Declaratory entries serve only to confirm changes that have already taken place within the company. This means that the legal effect of a given change arises before its registration, while the entry in the KRS merely confirms the existing state of affairs vis-à-vis third parties.

Examples of declaratory entries include:

change of the company’s address without changing the town or city of its registered office,
changes in the composition of the company’s governing bodies, such as the appointment of a new management board member, or changes affecting the supervisory board,
change of shareholders as a result of the sale of shares,
granting of commercial proxy,
commencement of the company’s liquidation.

Constitutive Entries in the KRS

Constitutive entries have a creating effect. This means that a given change produces legal effects only once it has been entered in the KRS. Without such an entry, the change does not exist in law.

Examples of constitutive entries include:

amendment to the articles of association, such as an increase or reduction of the share capital,
change of the company’s name,
transformation of the company,
registration of a newly formed company in the KRS.

Understanding the difference between declaratory and constitutive entries is of great importance for proper company management, as it determines the order and scope of actions required in a given case.

How to Register Company Changes with the KRS Business Register

Registering changes with the KRS is a process that requires diligence and compliance with specific formal requirements. The registration process may differ depending on the legal form of the entity and the type of change being reported

Where Should the KRS Application Be Submitted?

The application should be submitted to the registry court with jurisdiction over the company’s registered office. In Poland, registry courts operate within district courts.

Any update application must be directed to the registry court that has geographic jurisdiction over the company's registered office address. In the Polish legal system, these specific registry units operate within the district courts.

How to Submit an Application to the National Court Register?

Since 1 July 2021, all applications to the KRS business register have been submitted exclusively in electronic form via the Court Registers Portal or the S24 platform. Applications must be signed with a qualified electronic signature or a trusted signature (trusted profile), or personal signature (e-ID).

Required Documents to Change Company Details in the KRS

The application must be accompanied by the relevant documents, depending on the type of change being registered, such as:

resolutions of the company’s governing bodies,
consolidated text of the articles of association,
list of shareholders in the case of a limited liability company,
proof of payment of court fees,
financial documents or financial statements, if they are relevant to the registration of the specific change.
power of attorney if the application is submitted by an attorney, usually an advocate or attorney-at-law.

KRS Registration Costs and Waiting Time

The costs related to the application vary depending on how it is submitted:

PLN 350, including PLN 250 for the entry in the register and PLN 100 for publication in the Court and Commercial Gazette,
PLN 300 when using the S24 system, including PLN 200 for the entry in the register and PLN 100 for publication in the Court and Commercial Gazette.

The time required for the registry court to process the application usually ranges from several weeks to several months, depending on the court’s workload and the correctness of the submitted documents.

Liability for Failure to Report Changes to the National Court Register

Failure to comply with the obligation to report changes to the KRS may lead to serious legal and financial consequences.

Compulsory Proceedings Before the Registration Court

The registry court may impose a fine on members of the management board in order to compel them to report the changes. Such fines may amount to up to PLN 15,000 and may be imposed repeatedly.

To enforce reporting compliance, the registry court can penalize management board members who fail to submit company updates. These fines can reach up to PLN 15,000 and can be issued multiple times until the changes are reported.

Civil Liability of the Company’s Management Board

Members of the management board may be liable for damage caused by a failure to update data in the KRS if third parties suffer losses as a result of inaccurate data.

Deletion of the Company from the KRS

This sanction may be applied where, despite two requests from the registry court, the company has failed to submit the relevant application for registration of changes.

Risk of Losing Business Credibility

Out-of-date data in the KRS may harm the company’s reputation and negatively affect its relations with business partners.

Summary: Updating Company Details in the KRS

Managing a company requires its structure to be continuously adapted to changing needs and regulations. Registering changes with the KRS is a process which, when carried out with due diligence, helps avoid potential legal and financial problems.

What is the National Court Register in Poland?

The National Court Register, commonly referred to as the KRS, is the main national register containing basic data on companies, partnerships, associations, foundations and other legal entities operating in Poland. It includes information such as the entity’s identification data, legal form, legal status, registered address, business activity and details of the company’s management board.

What information can be found in the KRS business register?

The KRS business register contains key information needed to verify an entity involved in economic transactions. This may include the company’s name, registered office, tax identification number, contact details, e-mail address, company’s articles, bank account numbers and information on persons authorised to represent the company.

Which entities are subject to registration in the KRS?

Entities subject to registration in the KRS include commercial companies and partnerships, foundations, associations, trade unions, professional and other social organisations, independent public healthcare institutions and other legal entities required by law to be entered in the register. The KRS also includes, in specific cases, branches of foreign entrepreneurs operating in Poland.

Why is it important to keep KRS data up to date?

Keeping KRS data up to date is important because the register is used by contractors, banks, public authorities and the tax office to verify the company’s legal status and representation. Outdated data may create practical difficulties, for example with a bank account, tax matters or social security contributions.
