Corporate Law in Poland: A Complete Guide for Foreign Investors and Expats (2026)

Company formation, mergers, acquisitions, joint ventures and corporate governance in Poland.

Poland has one of the most active corporate legal markets in Central and Eastern Europe. For foreign investors setting up a business, acquiring a company or navigating a joint venture, understanding the local corporate law framework is essential — and finding a lawyer who can communicate in English is the first practical step.

Company Types Available to Foreign Investors

Polish corporate law, governed primarily by the Commercial Companies Code (Kodeks spółek handlowych), offers several vehicles for doing business. The most common choice for foreign investors is the spółka z ograniczoną odpowiedzialnością (sp. z o.o.), equivalent to a limited liability company. It requires a minimum share capital of PLN 5,000 (roughly €1,100), can be formed by a single shareholder including a foreign company, and offers liability limited to contributions.

For larger operations, a joint-stock company (SA) is appropriate, particularly if capital markets access is anticipated. The minimum share capital is PLN 100,000. Both structures allow 100% foreign ownership — Poland has no restrictions on foreign shareholding under EU law.

Branches (oddział) and representative offices (przedstawicielstwo) are also available but carry more limitations: branches can trade but must use the parent company's name; representative offices can only promote and advertise, not generate revenue.

Company Registration: The S24 System

Since 2012, Poland has offered online company registration through the S24 system, which can incorporate a standard sp. z o.o. in 24 hours. However, using S24 is only practical for simple structures with standard articles of association. Most foreign investors engage a law firm to prepare tailored articles, negotiate shareholders' agreements and manage the notarial process. For companies with non-standard provisions — veto rights, drag-along/tag-along clauses, dividend preferences — notarial deed formation is necessary.

Registration ultimately takes place at the National Court Register (KRS). A Polish lawyer will manage correspondence with the KRS, obtain a REGON statistical number and NIP tax identification number, and set up a company bank account on your behalf.

Mergers and Acquisitions

Poland's M&A market has been robust, with Warsaw-based firms consistently appearing in Mergermarket's top-10 European deal tables by volume. White & Case and Clifford Chance are consistently ranked Band 1 by Chambers Europe for M&A transactions.

Key steps in a Polish M&A transaction include: due diligence (legal, financial, tax), share purchase or asset purchase agreement (SPA/APA), regulatory filings (competition clearance from UOKiK if thresholds are met), and KRS registration of new ownership. Cross-border transactions involving EU-regulated sectors (energy, financial services, defence) may also require Polish government approval under the FDI screening law introduced in 2020.

Corporate Governance and Ongoing Obligations

A sp. z o.o. requires annual financial statements filed with the KRS, a shareholders' meeting at least once a year to approve those statements, and (if the supervisory board threshold is triggered) a supervisory board of at least three members. For foreign-owned entities, appointing a Polish-resident management board member is not legally required but is practically advisable for day-to-day bank and administrative interactions.

Polish corporate law was significantly updated by the Simple Joint Stock Company (PSA) introduced in 2021, designed for startups and technology companies. The PSA allows share capital as low as PLN 1, digital share ledgers, and flexible governance — it has become the vehicle of choice for venture-capital-backed businesses.

Finding the Right Corporate Lawyer in Poland

For corporate work, the leading international firms (White & Case, Clifford Chance, Linklaters, Dentons) offer the deepest bench and are best suited to complex cross-border transactions. For mid-market deals and ongoing corporate housekeeping, top Polish independents — Wardyński & Partners, Rymarz Zdort, SK&S — offer comparable quality at lower hourly rates.

When selecting a firm, confirm that the lead partner is admitted to practice in Poland (member of the Polish Bar or Law Society), that the engagement letter is in English, and that the firm has prior experience acting for clients from your home jurisdiction.

Costs and Timelines

Legal fees for a standard sp. z o.o. formation run from PLN 3,000 to PLN 8,000 for a reputable firm, depending on complexity. M&A transactions are typically billed at hourly rates (senior partners: €350–€600/hour at international firms, €200–€350 at Polish independents) or on a deal-value percentage basis for smaller transactions. Company registration with the KRS takes 2–4 weeks for notarial-deed incorporations, or 24 hours via S24.

Setting Up a Company in Poland

Poland offers several business structures for foreign investors, with the limited liability company (spółka z ograniczoną odpowiedzialnością, or sp. z o.o.) being the most popular for expat entrepreneurs. The sp. z o.o. can be formed with a minimum share capital of PLN 5,000 and can be established online through the S24 system or before a notary.

A corporate lawyer can advise on the optimal structure for your business, taking into account taxation, liability, governance requirements, and exit options. For larger ventures, a joint-stock company (spółka akcyjna, or S.A.) may be more appropriate, particularly if you plan to raise external investment or list on the Warsaw Stock Exchange.

The registration process typically involves preparing the articles of association, registering with the National Court Register (KRS), obtaining a NIP tax number and REGON statistical number, and potentially registering for VAT. A lawyer familiar with Polish company formation can streamline this process considerably.

Corporate Governance and Compliance

Once established, Polish companies must comply with ongoing governance requirements including annual financial statements, shareholder meetings, and director registration updates. Foreign shareholders and directors should be aware that Polish corporate law imposes fiduciary duties on management board members that differ in some respects from common law jurisdictions.

Corporate lawyers assist with drafting shareholders' agreements, managing board composition and decision-making procedures, handling dividend distributions, and advising on related-party transactions. For companies with foreign shareholders, transfer pricing documentation and substance requirements have become increasingly important under Polish and EU tax rules.

Data protection compliance under GDPR is another area where many foreign-owned Polish companies need legal assistance, particularly around cross-border data transfers and employee data processing.

Mergers, Acquisitions and Restructuring

Poland is one of the most active M&A markets in Central and Eastern Europe, with deal activity across technology, manufacturing, real estate, and financial services. Foreign acquirers should be aware that certain sectors require regulatory approvals, and that national security reviews may apply to acquisitions of Polish strategic assets.

A comprehensive M&A transaction in Poland will typically involve due diligence (legal, financial, and tax), negotiation and drafting of transaction documents, regulatory filings, and post-closing integration. Polish corporate lawyers experienced in cross-border transactions can manage these processes efficiently and ensure the transaction achieves the intended commercial objectives.

Common structures include share deals, asset deals, and mergers. Each has different implications for liability assumption, tax treatment, and third-party consents. Your legal adviser should work closely with tax advisers and, where applicable, employment lawyers to ensure a comprehensive approach.
