Quick answer: KRS or CEIDG depends on your legal form
Use CEIDG (Centralna Ewidencja i Informacja o Działalności Gospodarczej) if you operate as a sole proprietorship (jednoosobowa działalność gospodarcza) or as partners in a civil partnership (spółka cywilna, where each partner registers their own sole proprietorship in CEIDG). Use KRS (Krajowy Rejestr Sądowy, the National Court Register) if you are forming a commercial company or partnership under the Commercial Companies Code, such as a sp. z o.o. (limited liability company), S.A. (joint-stock company), spółka jawna (registered partnership), spółka komandytowa (limited partnership), or foundation/association conducting business.
If you are a foreigner, eligibility to register a sole proprietorship in CEIDG depends on your citizenship and residence basis. Rules can vary with your permit or status, so check current conditions with an official source before choosing the form.
What is CEIDG and who can use it?
CEIDG is the central online register for sole proprietors in Poland. When you file a CEIDG-1 application, you create or update your entry as an individual entrepreneur. Partners of a spółka cywilna each file their own CEIDG entry; the civil partnership itself is not entered in KRS.
You typically file CEIDG applications online using a Profil Zaufany (trusted profile) or a qualified electronic signature. Some foreigners without a PESEL may need to submit via a municipal office (urząd gminy/miasta) or use a qualified signature; practical options depend on your identity documents and access to eID. The CEIDG form also lets you indicate tax form preferences, PKD activity codes, and social security (ZUS) payer status.
After submission, NIP (tax identification) and REGON (statistical number) are usually assigned through connected systems. If you plan to be a VAT payer or trade services/goods with other EU countries, you make a separate filing to your tax office for VAT-R and, where relevant, VAT-UE registration.
What is KRS and who needs it?
KRS is the court-maintained register for commercial companies and partnerships. If you are creating a sp. z o.o., S.A., spółka komandytowa, spółka jawna or similar forms, you submit your incorporation and registration application to KRS. Many founders use the electronic S24 portal with standard templates or the e-KRS (PRS) filing system after signing notarial documents.
A typical KRS filing includes the company’s articles, registered address, management board details, share structure (for companies), PKD codes, and statements required by law. The process also covers requesting NIP and REGON allocation via integrated systems; however, tax, VAT, and other registrations may require separate or follow-up filings depending on your case.
Most KRS-registered entities must also report beneficial owners to the Central Register of Beneficial Owners (CRBR) shortly after registration. This is a separate online obligation with deadlines set by law; check the current rules before or immediately after you register.
Identifiers you get: NIP, REGON, KRS — and what they are for
KRS number: Assigned only to entities registered in the National Court Register. It is your court register ID and appears on official extracts (odpis KRS). Sole proprietors do not have a KRS number.
NIP: The tax identification number used for invoices, tax filings, and VAT. Both CEIDG and KRS entities use NIP. If you have never had a NIP, it is typically assigned during or just after registration. If you had a personal NIP previously, that number generally continues for your sole proprietorship.
REGON: The statistical number issued by GUS for identification in national statistics and some administrative processes. Both CEIDG and KRS entities have REGON. Your bank, clients, and portals may request it.
VAT-R and VAT-UE: These are separate tax registrations. You register as a VAT payer (VAT-R) if your activity requires or you choose to be a VAT taxpayer; VAT-UE enables intra-EU VAT identification. Thresholds and exemptions can change, and sector-specific rules apply, so verify with your tax office or a licensed adviser before you invoice.
How to choose: a practical decision checklist
Liability tolerance: CEIDG exposes your personal assets to business liabilities. A sp. z o.o. created via KRS can limit shareholder liability to contributions, but directors still have duties and risks. If limiting liability is a priority, consider KRS forms.
Ownership and funding: If you need multiple shareholders, investor participation, employee shares, or structured governance, KRS companies (notably sp. z o.o. or S.A.) are usually more suitable than CEIDG.
Taxes and accounting: CEIDG offers individual income tax methods and simplified accounting options subject to limits and activity types. KRS companies are subject to corporate income tax (CIT) and typically have full accounting. Your optimal route depends on expected margins, reinvestment plans, and distribution needs; get professional tax advice before choosing.
Operational perception: Larger clients, tenders, or cross-border contracting sometimes prefer company forms (e.g., sp. z o.o.) for continuity and risk management. On the other hand, freelancers and micro-businesses often value CEIDG for speed and low overhead.
Administrative access: Do you have PESEL, Profil Zaufany, and a Polish address for service? CEIDG is smooth with eID. For KRS, you will sign before a notary or use S24/e-KRS with qualified e-signatures. Foreign directors may need apostilled documents or translations; check requirements early.
Exit and growth: If you plan to add co-founders, raise capital, or sell the business, starting with a KRS company may reduce restructuring later. If you are validating a solo service, CEIDG may be a faster first step.
Common pitfalls and what to prepare before filing
Names and PKD: Check your proposed business name for uniqueness (KRS) and clarity (CEIDG). Choose PKD codes that actually match your planned activities; some regulated activities require permits. Misaligned PKD can delay VAT or cause banking questions.
Digital identity and signatures: Ensure you have Profil Zaufany or a qualified signature well before your target filing date. Foreign directors without PESEL should plan for notarial acts or qualified e-signatures and any required sworn translations.
Registered address: You need a registered office or correspondence address. Virtual offices are common but confirm they accept official mail and KRS/CEIDG service. Some banks and counterparties prefer physical addresses.
Post-registration obligations: Do not forget ZUS payer registration when you hire or when contributions apply, VAT-R if needed, CRBR for KRS entities, and any sector licences (e.g., BDO for certain waste-handling activities). Bank account opening can require KRS/CEIDG extracts, NIP/REGON confirmations, and UBO declarations.
Scenarios: which registry fits these real cases?
Solo IT consultant billing Polish and EU clients: If eligible to register a sole proprietorship, CEIDG can be the fastest route. You would obtain NIP/REGON via CEIDG, consider VAT-R and VAT-UE if your clients require VAT invoices or you exceed exemption thresholds, and open a business bank account with CEIDG confirmation. If you anticipate liability risks or plan to onboard co-founders soon, forming a sp. z o.o. via KRS may be wiser despite higher setup and accounting formality.
Two co-founders building a product with outside investors: Go directly to a KRS company, typically a sp. z o.o. Define shareholdings, management board, vesting arrangements in the articles or shareholder agreements, file KRS via S24 or a notary, obtain NIP/REGON, register in CRBR, and handle VAT/CIT registrations as required. Prepare cap table documents early; investors and banks will ask for a clean KRS extract and UBO filing.
Non-EU national on a temporary stay planning to start quickly: Before assuming CEIDG is possible, verify your residence basis allows a sole proprietorship. If not, a KRS form like sp. z o.o. is often used by foreign founders. Check director/shareholder documentation, signatures, and translation needs in advance to avoid resubmissions.
