EU Inc. in Poland: what it means for foreign investors?

EU Inc. is a new harmonised limited liability company form proposed by the European Commission, with core corporate rules designed to apply across all EU Member States, including Poland. The proposal includes fully online registration within 48 hours at a maximum cost of EUR 100 under the fast-track procedure, no minimum share capital, a digital register of shares and simplified investment procedures. However, EU Inc. would not replace national tax systems, labour law or all local administrative obligations. For businesses operating only in Poland, its advantages over existing Polish company forms may be limited. For companies expanding simultaneously across several EU markets, however, the new model could significantly reduce certain legal and corporate costs.

EU Inc. in Poland is intended to address a specific problem faced by businesses scaling across Europe: the Single Market covers 27 Member States, yet companies still operate under many different national company-law systems. The European Commission points out that more than 60 national company forms exist across the EU, while differences in registration, share structures, financing and corporate documentation increase the cost of cross-border expansion.

For an investor planning to operate in Poland, the key question is therefore not simply “what is EU Inc.?”, but whether the new company form will genuinely make it possible to operate in Poland and other EU countries under one common set of corporate rules.

What is EU Inc. and how would the EU’s 28th regime work?

EU Inc. would be an optional EU company form operating alongside national company forms, rather than replacing them. Entrepreneurs would still be able to choose a Polish limited liability company (sp. z o.o.), a simple joint-stock company (PSA) or another legal form available under Polish law.

The term 28th regime refers to an additional set of common rules available alongside the 27 national legal systems. Under the European Commission’s proposed Regulation COM(2026) 321, EU Inc. would be a limited liability company with legal personality and shareholders who are not liable for the company’s obligations. It could be established by one or more natural or legal persons. Founders would be able to choose the EU Member State in which the company is registered. Once entered in the relevant business register, the EU Inc. company’s legal personality would be recognised across all Member States. This would not, however, mean that national law ceases to apply. The proposal expressly provides that an EU Inc. would be governed by the Regulation and its articles of association and, for matters not regulated at EU level, by the applicable law of the Member State of its registered office.

Can an EU Inc. company be incorporated in Poland?

Yes. If the Regulation is adopted in the form proposed by the Commission, an EU Inc. could also be registered in Poland and operate as an alternative to Polish company forms.

The proposal provides for an EU central interface based on the Business Registers Interconnection System (BRIS). Under the fast-track procedure using harmonised articles of association, registration would be completed within 48 hours and at a maximum cost of EUR 100. The entire procedure would be available online.

The proposal also extends the once-only principle. Following registration, the competent business register would electronically transmit registration data to authorities responsible for matters including tax and VAT identification numbers, social security and beneficial ownership registers. As a rule, the company would not have to submit the same information again.

For a foreign entrepreneur choosing Poland, this could reduce some of the administrative work required when starting operations. It should not, however, be confused with a single European tax system or a single set of rules for employing staff.

What would EU Inc. actually simplify for a company operating in Poland?

Area	Proposed EU Inc. model	Business relevance
Registration	fully online procedure; fast-track registration within 48 hours and at a maximum cost of EUR 100	faster market entry and fewer formalities
Capital	no minimum share capital; capital may be set at EUR 0	lower formal barrier to entry
Shares	digital register of shares, different classes of shares and investment instruments	simpler structures for investors and funding rounds
Documents	harmonised templates and an EU central interface	less need to adapt corporate documentation to different Member States
Management	board of directors consisting of one or more directors; at least one must be resident in the EU	greater flexibility in building an international management structure
Registry data	use of BRIS and the once-only principle	less repetitive submission of the same information to public authorities

The proposal is therefore about considerably more than fast registration. The Commission proposes common rules covering a substantial part of the company lifecycle, including corporate organisation, shares, share transfers, raising capital, reorganisations and dissolution.

The investment dimension may be particularly important. The proposal provides for a digital register of shares and mechanisms supporting financing instruments commonly used by venture capital investors. The Commission also proposes a common EU employee stock option plan (EU-ESO).

According to the Commission’s impact assessment, the total reduction in administrative burden could amount to EUR 328–440 million over 10 years, assuming approximately 308,000 companies use the 28th regime. This is an estimate for the EU as a whole, with startups and rapidly scaling companies expected to benefit most.

What would EU Inc. not simplify? Taxes remain a key issue

EU Inc. would not create a single tax system for companies operating across the European Union. This is one of the most important limitations for investors assessing the proposed company form.

The European Commission treats tax harmonisation as a separate area, including initiatives such as the Head Office Taxation System and Business in Europe: Framework for Income Taxation (BEFIT). Choosing EU Inc. would therefore not, in itself, remove the need to analyse tax residence, permanent establishments, VAT, transfer pricing or the taxation of operations conducted in individual Member States.

The same applies to employment. EU Inc. is designed to harmonise part of company law, not to create a single European labour code. A business employing staff in Poland would still have to comply with Polish labour law applicable to work performed in Poland, as well as the relevant social security rules.

Taxation, applicable law and jurisdiction, and the relationship between EU Inc. and national employment rules have been among the practical issues raised during discussions on the proposal. During the May debate in the Council of the European Union, delegations also highlighted the need for safeguards concerning areas including taxation, anti-money laundering requirements and labour rights.

Businesses should therefore not treat EU Inc. as a mechanism allowing them to “register once and operate everywhere without local obligations”. What is intended to be harmonised is primarily the company’s corporate-law foundation, not the entire regulatory environment in which the business operates.

Would EU Inc. be better than a Polish limited liability company or joint-stock company?

Not for every business. The strongest case for EU Inc. is likely to arise where there is a cross-border element from the outset: foreign shareholders, investors from several countries or plans for rapid expansion into additional EU markets.

For a business operating solely in Poland, familiarity with the Polish limited liability company (sp. z o.o.), established legal practice and well-developed accounting and administrative procedures may continue to offer significant value. EU Inc. would not in itself provide a lower corporate income tax (CIT) rate or remove obligations arising under Polish tax and employment law. Before selecting a structure, investors may therefore also wish to compare the main legal forms available to companies in Poland.

Another natural point of comparison is the Polish simple joint-stock company (PSA). Polish legal analysis highlights several similarities between the PSA and the proposed EU Inc. model, including a flexible approach to capital and digital recording of shareholder rights. The key difference, however, is scale. The PSA is a company form governed by Polish law, whereas EU Inc. is intended to provide a single recognisable corporate standard for investors from France, Germany, the Netherlands or any other EU Member State. For funding rounds or groups operating across several countries, this could reduce the need to analyse a different national company-law structure each time.

Can an existing Polish company be converted into an EU Inc.?

The proposal provides for this possibility. EU Inc. is intended to be available not only to newly established businesses but also to existing companies.

The Commission’s proposal allows an EU Inc. to be formed through, among other routes, a domestic conversion, merger or division of an existing company, as well as through specified cross-border reorganisations. For domestic operations, however, the proposal introduces a condition: at least two years must have passed since the company’s registration, or its first two annual financial statements must have been approved. The domestic reorganisation procedure itself would remain subject to the applicable national law. This does not mean that converting a Polish company into an EU Inc. would always be tax-neutral. The CIT, VAT, tax-loss, relief, asset and group-reorganisation consequences would have to be assessed under the rules applicable at the time of the transaction.

For international groups, this may become one of the most important considerations when assessing EU Inc.: the benefits of a simpler corporate structure will need to be weighed against the costs and consequences of migrating from an existing national structure.

When will EU Inc. enter into force?

There is currently no binding launch date for EU Inc. Companies cannot yet be registered in this form in Poland or in any other EU Member State.

The European Commission presented the proposal on 18 March 2026. The legislative procedure is registered as 2026/0074(COD) and is being conducted under the ordinary legislative procedure. According to the European Parliament’s current Legislative Observatory data, the proposal is awaiting a decision by the Committee on Legal Affairs (JURI), while 5 October 2026 is listed as the indicative date for the first plenary reading.

Negotiations are also continuing in the Council. A first Presidency compromise text was prepared on 17 July 2026 and subsequently discussed by the Working Party on Company Law.

The EU institutions have indicated a political objective of reaching agreement by the end of 2026, but this would not automatically mean that EU Inc. companies could be established from the beginning of 2027. Importantly, the Commission’s current proposal provides for the Regulation to apply only 12 months after its entry into force.

It would therefore be premature to present any specific launch date for EU Inc. as final. The timetable will depend on when the Regulation is adopted and on the wording of the final legislation.

Should investors planning to enter Poland wait for EU Inc.?

No. EU Inc. may make European expansion easier in the future, but at the current stage it is not a reason to delay an investment in Poland.

A company planning to enter the Polish market should first determine where its actual business activities will take place, where employees will work, where management decisions will be made and where revenues will be generated. These factors — together with the country of registration and chosen legal structure — largely determine tax, payroll and administrative obligations. Under the EU Inc. proposal, the accounting rules of the Member State in which the company has its registered office would apply.

EU Inc. will be particularly worth monitoring for businesses that:

• plan to operate simultaneously in several EU Member States,
• intend to raise capital from international investors,
• are building a European holding or technology structure,
• expect frequent funding rounds and changes in ownership,
• compete internationally for highly skilled employees.

For foreign investors, Poland would remain one of the possible Member States in which an EU Inc. could be registered and operate. The new company form would not, however, change the fundamental principle that the choice of legal form is only one part of an investment-location decision. Taxation, labour costs and availability, infrastructure, financing and the wider regulatory environment will remain equally important.

What is the practical conclusion for investors considering EU Inc. in Poland?

EU Inc. is one of the most far-reaching initiatives in recent years aimed at simplifying company law within the Single Market. If the final Regulation retains the core elements of the Commission’s proposal, entrepreneurs will be able to use one legal form, digital procedures and a more consistent corporate structure regardless of the Member State selected for registration.

The greatest value may arise for businesses where the Polish market forms part of a broader European strategy. EU Inc. could reduce fragmentation in company law, but it would not eliminate fragmentation in taxation, employment or day-to-day operations. When choosing in the future between EU Inc. and a Polish limited liability company or PSA, the decisive factor should therefore be the target operating model across the EU, rather than registration speed alone.
