CEIDG or KRS: Where to Register Your Business in Poland?

The short answer: CEIDG vs KRS, which one to use

Register in CEIDG if you are starting a sole proprietorship (jednoosobowa działalność gospodarcza, often abbreviated JDG) or if you are an individual partner in a civil partnership (spółka cywilna). Register in KRS (Krajowy Rejestr Sądowy, the National Court Register) if you are setting up a company or commercial partnership such as a spółka z ograniczoną odpowiedzialnością (sp. z o.o.), spółka akcyjna (S.A.), spółka jawna (sp.j.), or spółka komandytowa (sp.k.), as well as foundations and associations.

Choose the register based on your legal form and your eligibility to operate as a sole proprietor in Poland. If in doubt, verify with the official CEIDG and KRS portals or consult a qualified adviser. This article gives general guidance, not legal or tax advice.

Which legal forms belong to each register

CEIDG (Centralna Ewidencja i Informacja o Działalności Gospodarczej) is a public register of natural persons conducting business. You use CEIDG to start, suspend, resume, or close a sole proprietorship. Partners in a spółka cywilna each have their own CEIDG entry; the civil partnership itself also obtains identifiers for tax and statistics, but it is not a company under the Code of Commercial Companies.

KRS (Krajowy Rejestr Sądowy) is run by commercial courts and covers entities that are separate from their owners. This includes limited liability companies (sp. z o.o.), joint-stock companies (S.A.), limited partnerships (sp.k.), general partnerships (sp.j.), professional partnerships (sp.p.), simple joint-stock companies (Prosta Spółka Akcyjna, P.S.A.), cooperatives, foundations, and associations. These entities file to KRS either via the online eKRS system or the S24 portal for template-based incorporations.

Can a foreigner use CEIDG? What many founders choose instead

Eligibility to run a sole proprietorship in CEIDG depends on your citizenship and the type of residence rights you hold in Poland. Some non-Polish citizens can register a JDG if they have specific residence statuses. Others may not be eligible. Because these rules can change and hinge on personal circumstances, verify your situation with the official CEIDG guidance or an immigration/legal adviser before you start.

KRS-based companies such as a sp. z o.o. are commonly chosen by foreign founders because they offer limited liability and do not require the owner to qualify for sole proprietorship status. Incorporation can be done online in many cases, and ownership can be held by individuals or other companies. If you plan to bring on co-founders or investors, hire staff, or separate personal and business liability, a KRS-registered company is often the practical route.

What the registry entry contains and why partners check it

A CEIDG entry displays the entrepreneur’s identifying data, business name, PKD activity codes (Polish classification of activities), addresses, and status (active/suspended). Since it links to a natural person, counterparties often treat a JDG as lower-complexity but higher personal liability for the owner.

A KRS extract shows a company’s registered details: name, KRS number, seat address, management board members and representation rules, share capital information, and any appointed proxies. It also indicates liquidations or bankruptcy status. Banks, suppliers, and public authorities regularly verify KRS data to confirm who can sign contracts and make binding declarations. Expect to be asked for a recent KRS extract and the company’s NIP (tax number) and REGON (statistical number) when opening accounts or bidding for contracts.

What to prepare before you file (CEIDG and KRS checklists)

For CEIDG (sole proprietorship): prepare your identification data, addresses, and contact email/phone; your business name (often your surname is required to appear in the name); PKD codes that describe your activities; preferred tax form and accounting method (these have legal and tax effects—get professional advice if unsure); ZUS social insurance selections; and bank account details if already available. If you plan to register for VAT (VAT-R), collect the supporting documents your tax office may request. Many filings are made online via a Trusted Profile (Profil Zaufany) or qualified signature.

For KRS (companies/partnerships): decide the legal form; propose a company name; determine the registered seat and service address; define the scope of activity (PKD) and representation rules; identify shareholders/partners and management board members; prepare the articles of association (umowa spółki/statut)—either with a notary or via S24 templates; and gather identification data for ultimate beneficial owners (for CRBR, the Central Register of Beneficial Owners). After KRS entry, NIP and REGON are typically assigned via data exchange with tax/statistics authorities, but you will still need to file supplementary data on official forms (for example, NIP-8) within the required timeframe. If VAT registration is needed, plan it early; some banks or clients will ask for VAT status. Requirements and timelines can vary by form and local office, so always check current official instructions.

Worked scenarios: which register fits

Freelance IT consultant living in Poland: If you have a residence status that allows a sole proprietorship and you want a simple setup with minimal formalities, CEIDG for a JDG can be suitable. You’ll file CEIDG with your PKD codes (e.g., software-related codes) and select your tax form. Remember that liability is personal; your own assets back the business.

Non-EU founder planning to hire and raise investment: A sp. z o.o. registered in KRS is typically the practical choice. It provides limited liability, accommodates multiple shareholders, and is familiar to investors. You will incorporate via eKRS or S24, obtain KRS/NIP/REGON, appoint a management board, and report beneficial owners to CRBR. Budget time for bank account opening and any VAT registration your model requires.

Two friends opening a small café: A spółka cywilna seems easy because each partner registers in CEIDG, but it does not create a separate legal person and partners bear full liability. Many cafés instead choose a spółka jawna (KRS) or a sp. z o.o. (KRS) to separate business liabilities from personal assets. Which is better depends on financing, lease obligations, and risk tolerance—get tailored advice.

Avoid these common mistakes when choosing CEIDG or KRS

Trying to register a company in CEIDG or a sole proprietorship in KRS. The register follows the legal form, not your preference for paperwork simplicity.

Overlooking CRBR. Most KRS-registered companies and partnerships must report their ultimate beneficial owners shortly after registration. Missing this can lead to penalties—check the official CRBR guidance and deadlines.

Confusing personal and company identifiers. A JDG uses the owner’s NIP; a company gets its own NIP. Make sure invoices and contracts show the correct legal party and numbers.

Choosing a civil partnership without understanding liability. A spółka cywilna is based on the Civil Code and is not a separate legal person. If you need clearer liability separation or plan to scale, consider a KRS-registered entity.

Skipping PKD planning. Incomplete or inaccurate PKD codes can complicate VAT, licensing, or tenders. Review PKD codes carefully and update them if your activities change.

How to file and verify: next steps

Decide your legal form based on liability, eligibility, funding plans, and administration burden. If you are unsure, speak with a licensed legal or tax professional.

Check eligibility and documents. For CEIDG, confirm you meet residency/citizenship conditions for a JDG. For KRS, prepare your articles, shareholder data, and management board appointments.

Prepare PKD codes and addresses. Verify that your intended activities do not require additional permits or notifications. When needed, obtain professional translations or notarizations.

File online. Use the CEIDG portal for sole proprietorships and eKRS/S24 for companies and partnerships. After KRS registration, complete supplementary filings such as NIP-8 and the CRBR report within the official timelines, and handle VAT registration if required for your model.

Open a bank account and set up accounting. Banks may ask for KRS/CEIDG extracts, company documents, and identification of beneficial owners. Arrange bookkeeping and ZUS registration steps as applicable.
