A German technology company wants to establish a Polish subsidiary before the end of the quarter. Its CFO asks: how fast can we actually incorporate? The answer depends entirely on the route chosen. Through the S24 online portal operated by the Ministerstwo Sprawiedliwości (Ministry of Justice), a spółka z ograniczoną odpowiedzialnością (private limited liability company, sp. z o.o.) can be registered in the National Court Register (KRS) within 24 hours of submitting the application – sometimes faster.

The S24 system allows founders to incorporate a sp. z o.o. entirely online, without a notarial deed, using a standardised articles of association template. Registration takes place through the KRS electronic portal, with the court obliged to process the application within one business day of receiving a complete filing. The minimum share capital is PLN 5,000, divided into shares of at least PLN 50 each, and the statutory fee is PLN 250 plus a court announcement charge of PLN 100.

This guide walks through the S24 procedure step by step: who qualifies, what documents are required, where the process typically stalls, and how three different business scenarios – a Polish entrepreneur, a foreign investor, and a technology startup – each approach the same 24-hour window. The FAQ section addresses the questions we hear most often from clients setting up a company in Poland for the first time.

What is S24 and who can use it?

S24 is the Ministry of Justice's dedicated online incorporation system. It was designed to remove the notarial deed requirement from standard sp. z o.o. formations, reducing both cost and time. The system is integrated with the KRS portal, the Central Register of Beneficial Owners (CRBR), and the tax identification system. Founders create an account, authenticate via a trusted profile (profil zaufany) or qualified electronic signature, and submit the entire application digitally.

The key condition for using S24 is acceptance of the standardised articles of association. The template covers the essential elements: company name and registered office, object of business (selected from a list of PKD activity codes), share capital amount, number and value of shares, and the composition of the management board. Founders who need bespoke provisions – drag-along rights, reserved matters, veto rights for minority shareholders – cannot use S24. Those provisions require a notarial deed and the standard KRS registration track, which takes up to seven business days.

Eligible founders include natural persons and legal entities. However, a single-person sp. z o.o. cannot be formed by another single-person sp. z o.o. – Polish corporate law imposes this restriction to prevent circular sole-ownership structures. Foreign individuals can authenticate using a qualified electronic signature issued in any EU member state under the eIDAS regulation. Non-EU individuals without a Polish trusted profile face a practical barrier: they typically need a Polish attorney acting under a notarised and apostilled power of attorney, which adds two to five business days.

One further condition: share capital under S24 must be contributed in cash only. In-kind contributions – intellectual property, equipment, real estate – require the notarial route. This distinction matters for technology founders who intend to contribute a software licence or patent portfolio at the point of formation.

What are the step-by-step requirements for S24 registration?

The S24 procedure unfolds in five distinct stages, each with its own timeline and potential failure point. Understanding the sequence in advance prevents the delays that most commonly push registration beyond the 24-hour window. The court's one-business-day obligation begins only once a complete, fee-paid application is received – incomplete submissions restart the clock.

Stage one is account creation and authentication. Each founder – and each management board member – must hold a verified S24 account. Authentication via a trusted profile is free and takes up to 15 minutes for Polish nationals with a PESEL identification number. Foreign nationals using a qualified electronic signature must ensure it is compatible with the Polish system; incompatibilities are the single most common cause of delays we see in practice.

Stage two is drafting the articles of association within the S24 template. Founders select PKD activity codes, set the share capital (minimum PLN 5,000), allocate shares, and appoint the management board. The system validates entries in real time. A common mistake at this stage is selecting an overly narrow range of PKD codes, which later requires a costly amendment to the articles.

Stage three is signing. All founders sign the articles electronically within the S24 system. All management board members sign the statement confirming they meet the statutory requirements to serve as directors. Both sets of signatures must be completed before submission.

Stage four is payment. The court fee of PLN 250 and the announcement fee of PLN 100 are paid via the integrated payment module. The application is formally lodged only after payment confirmation is recorded.

Stage five is KRS review. The registry court – a dedicated department of the district court (sąd rejonowy) for the company's registered office – must process the application within one business day. Upon registration, the company receives its KRS number, NIP tax identification number, and REGON statistical number simultaneously. The company exists as a legal entity from the moment of registration, not from the moment of signing the articles.

How do three business scenarios play out in practice?

The 24-hour promise looks different depending on who is using it. Three scenarios illustrate the range of outcomes – and the specific risks each type of founder should anticipate before submitting.

Scenario one: Polish entrepreneur. A sole trader in Mazowieckie decides to convert her consulting practice into a sp. z o.o. She holds a trusted profile, has a Polish PESEL number, and is contributing PLN 10,000 in cash. For her, S24 is straightforward. She completes the articles template in under an hour, signs electronically, pays the fees, and receives KRS confirmation the following morning – within 18 hours of submission. The main post-registration task is opening a corporate bank account, which typically takes three to five business days depending on the bank's AML procedures. We assisted a client in a comparable situation in Mazowieckie (winter 2025), and registration was confirmed within 14 hours of submission.

Scenario two: Foreign investor entering Poland. A Czech manufacturing group wants a Polish subsidiary to bid on a public contract beginning in 60 days. The parent company is a legal entity, so it must be represented by an authorised person in S24. That person needs either a Polish trusted profile or a compatible qualified electronic signature. If neither is available, the group's Polish counsel can act under a notarised and apostilled power of attorney – but preparing that document takes at least five business days, consuming a significant portion of the available window. For clients in this position, we often recommend beginning the power of attorney process in parallel with internal corporate approvals. For background on acquisition-related due diligence considerations in Poland, see our analysis of red flags in Polish M&A for Czech Republic buyers.

Scenario three: Technology startup with two founders. Two Polish nationals are forming a software company. They plan to contribute a software licence as part of their equity – but under S24 rules, only cash contributions are permitted. They must either contribute PLN 5,000 in cash now and transfer the licence post-registration as a subsequent transaction, or use the notarial route from the outset. Choosing S24 for speed and then attempting to bring in the licence informally creates a valuation and tax risk that can surface during any future due diligence process. Our team helped a Małopolska-based IT startup restructure exactly this arrangement (spring 2026), avoiding a PLN 80,000 tax exposure identified during a pre-investment review.

The decision matrix is straightforward: if all founders can authenticate electronically, share capital is cash only, and standard articles are acceptable, S24 delivers a registered company in one business day at a total statutory cost of PLN 350. Any deviation from those three conditions shifts the analysis toward the notarial route.

What are the most common mistakes and how do you avoid them?

Speed creates its own risks. The S24 system is designed to be self-service, but the standardised template cannot anticipate every commercial situation. The mistakes described below account for the majority of post-registration amendment filings we review – each amendment costs PLN 250 in court fees and takes up to three business days to process.

  • Insufficient PKD codes. Selecting only one or two activity codes at formation is the most frequent error. Adding codes later requires an amendment to the articles and a new KRS filing. Founders should list all foreseeable activities from the outset.
  • Wrong registered office address. The registered office determines which district court holds jurisdiction over the company. Entering a temporary or incorrect address creates complications when the company later moves – a formal amendment is required each time.
  • Delayed share capital payment. Under S24, founders must contribute the full PLN 5,000 minimum within seven days of registration. Failure to do so is a breach of the management board's obligations under the Kodeks spółek handlowych (Commercial Companies Code, KSH) and can expose directors to personal liability.
  • Missing CRBR notification. Within seven days of KRS registration, the company must report its beneficial owners to the Central Register of Beneficial Owners. Failure to file triggers a fine of up to PLN 1,000,000 – one of the most severe penalties in Polish corporate compliance.
  • Overlooking VAT registration. S24 registration does not automatically register the company for VAT. A separate application to the relevant tax office must be submitted, typically before the company issues its first invoice.

The CRBR deadline is the one that surprises foreign investors most. Many assume that KRS registration completes the incorporation process. It does not. The beneficial ownership report is a separate obligation, and the PLN 1,000,000 ceiling on penalties makes it one of the highest-stakes compliance steps in Polish corporate law. For companies with complex ownership chains – common in M&A Poland transactions – identifying the ultimate beneficial owner requires careful analysis before the seven-day window closes.

ESG and governance reporting obligations are increasingly relevant from the point of formation as well. Companies with international investors or supply chain relationships should consider their reporting framework early. Our ESG and compliance practice provides guidance on ESG compliance in Poland for companies at every stage of development.

What to prepare before submitting your S24 application?

A complete S24 filing requires the following items to be ready before the session begins. Assembling them in advance is the single most effective way to stay within the 24-hour window. Missing any element forces the founder to abandon a partially completed session and restart.

  • Verified S24 accounts with active authentication for all founders and all proposed management board members
  • Agreed company name (checked against the KRS database for conflicts) and registered office address in Poland
  • Final list of PKD activity codes covering all planned business activities
  • Share capital amount (minimum PLN 5,000, cash only) and agreed share allocation among founders
  • Payment method ready for the PLN 350 statutory fee (PLN 250 court fee plus PLN 100 announcement fee)

Foreign founders should add two further items: confirmation that their qualified electronic signature is compatible with the Polish S24 system, and – if acting through counsel – a notarised and apostilled power of attorney prepared in advance. Building these steps into the project timeline, rather than treating them as afterthoughts, is what distinguishes a smooth 24-hour registration from a ten-day process.

Frequently asked questions

Q: Can a foreign company be the sole shareholder of a Polish sp. z o.o. formed via S24?

A: Yes, a foreign legal entity can be the sole shareholder, provided it is not itself a single-person sp. z o.o. The foreign company's authorised representative must hold a compatible electronic signature or a notarised power of attorney. The representative signs the articles of association and the management board statement on behalf of the foreign entity. The process adds at least five business days if the power of attorney needs to be prepared and apostilled abroad.

Q: How long does it take and what does it cost to amend the articles of association after S24 registration?

A: An amendment to the standardised S24 articles requires a resolution of the shareholders' meeting and a new KRS filing. The court fee is PLN 250, and the announcement fee is PLN 100. The registry court must process the amendment within three business days of receiving a complete filing. More substantive amendments – such as adding a supervisory board or introducing bespoke share rights – require conversion to a notarial deed, which adds notarial fees typically ranging from PLN 600 to PLN 2,000 depending on share capital.

Q: Is it a misconception that S24 registration automatically handles all tax registrations?

A: Yes, and it is a costly one. S24 registration with the KRS triggers automatic assignment of a NIP tax number and REGON statistical number. However, VAT registration is entirely separate. The company must submit a VAT registration form (VAT-R) to the relevant tax office before conducting any VAT-taxable activity. Failing to register before issuing the first invoice can result in denial of input VAT deduction rights on early purchases – a loss that cannot always be recovered retroactively.
