In 2025, an updated PKD classification entered into force. If you run a business and have not checked your codes yet, do so now. Outdated PKD codes mean a risk of problems with public authorities, loss of access to grants and tax complications. Below you will find specific information on what changed, the risks of doing nothing and how to update your codes step by step.
What is PKD?
PKD, the Polish Classification of Business Activities, is the official system of codes describing the type of your business activity. Every business, regardless of its legal form, must have PKD codes assigned that correspond to what it actually does.
Why does PKD matter for your business?
PKD is how public authorities, banks and contractors classify your business activity. Incorrect or outdated codes create specific risks:
- Risk of problems when registering with CEIDG or KRS. Codes that are too general can lead to misunderstandings with public authorities. Missing the appropriate PKD code may force you to make changes later, and these are not always quick or simple.
- Risk of additional tax inspections. Some business activities are subject to special rules. Online retail follows different rules from advisory services. An incorrect code may trigger an inspection and complications.
- Risk of losing access to grants. PKD determines whether you qualify for EU and national funds. If your code does not match a grant programme, you will not receive funding.
- Risk of losing public contracts. Many public procurement procedures and projects require specific PKD codes. Without them, you lose the opportunity to participate in tenders.
- Risk of higher ZUS contributions and document corrections. An unsuitable code affects the amount of contributions and reporting. The result may be higher charges or the need to correct documentation.
What changed in the PKD codes in 2025?
The update responded to economic and technological changes. The new classification aligns Polish codes with European standards.

Removal of outdated codes
Codes that no longer reflected market realities were discontinued.
What does this mean for you?
If you are already in business
Check your PKD codes in CEIDG or KRS and make sure they comply with the current classification. Failure to update them may lead to:
- problems with tax authorities and other public bodies,
- loss of the opportunity to participate in tenders,
- loss of access to grant programmes and financial support.
Updating your PKD codes is also an opportunity to reconsider the scope of your business and enter new areas.
If you are planning to start a business
The updated PKD classification helps you match the scope of your business to current market realities. The new code descriptions make registration easier and allow you to define the nature of your business precisely from the outset.
How to check and update PKD, step by step
- Check your current codes. Log in to CEIDG if you run a sole proprietorship, or KRS if you have a company, and review the codes assigned to your business.
- Compare them with the current classification. The full list is available on the website of Statistics Poland (GUS).
- Make changes. If you notice discrepancies, update the codes in CEIDG or KRS.

Summary
Changes to PKD codes are not a formality. They are a real risk if you ignore the update, and a real opportunity if you use it to organize the scope of your business. Check your PKD codes and adapt them to the applicable regulations. The sooner you do this, the fewer problems you may face in the future.
Frequently asked questions
What are PKD codes, and why are they important for my business? PKD (the Polish Classification of Business Activities) is the official system of codes describing the type of business activity. Every business in Poland, regardless of its legal form, must have codes assigned that correspond to what it actually does. PKD directly affects registration with CEIDG or KRS, eligibility for EU and national grants, participation in public procurement, the amount of ZUS contributions, and how public authorities, banks and contractors classify your business activity. Incorrect or outdated codes create a risk of tax inspections, loss of funding and registration complications.
What changed in the PKD classification in 2025? In 2025, an updated PKD classification entered into force, aligning Polish codes with European standards in response to economic and technological changes. New codes were introduced for innovative industries, the names of existing categories were clarified (for example, transport and logistics services received more detailed descriptions), and outdated codes that no longer reflected market realities were discontinued.
What risks do I face if my PKD codes are outdated or incorrectly selected? Outdated or incorrect PKD codes mean a risk of problems with tax authorities, additional tax inspections, loss of access to EU and national grants, and exclusion from tenders and public procurement. An unsuitable code also affects the amount of ZUS contributions and may require document corrections, which means higher charges and additional administrative work. Missing the appropriate PKD code at registration may also force later changes in CEIDG or KRS, which are not always quick or simple.
How can I check and update my PKD codes in CEIDG or KRS? Log in to CEIDG if you run a sole proprietorship, or KRS if you have a company, and review the assigned codes. Then compare them with the current classification on the Statistics Poland (GUS) website. If you notice discrepancies, make changes in the relevant register. If in doubt, consult an expert who can help select codes that meet current requirements and update the register.
Do the new PKD codes cover areas such as artificial intelligence, e-commerce and renewable energy? Yes. The updated 2025 PKD classification introduces new codes for services related to artificial intelligence and machine learning, e-commerce and digital platforms, and the production of renewable energy source (OZE) technologies. If you operate in these industries, check whether your current codes correspond to the new categories. This affects access to grants, tenders and correct registration.
