A German-based industrial group decides to expand into Poland. The finance director asks a simple question: do we open a branch or incorporate a subsidiary? The answer shapes tax exposure, liability, and operational flexibility for years ahead. Getting it wrong at the outset forfeits structural advantages that cannot easily be recovered later.

Polish law offers two primary vehicles for foreign groups entering the market: a registered branch (oddział) and a limited liability company (spółka z ograniczoną odpowiedzialnością, sp. z o.o.). A branch is a dependent extension of the parent, carrying no separate legal personality and exposing the foreign entity to unlimited liability in Poland. A subsidiary is an independent legal person registered in the National Court Register (KRS), with liability confined to its own assets. The choice between them determines how quickly the group can operate, how profits are repatriated, and whether board members face personal exposure.

This alert sets out the structural differences, identifies which groups are most affected by the choice, and lists immediate action items for groups already operating – or planning to operate – in Poland.

What distinguishes a branch from a subsidiary in Poland?

A branch is not a separate legal entity. It operates under the parent's name and legal identity, registered with the National Court Register (KRS) through a dedicated branch register. The parent company bears full liability for all obligations the branch incurs in Poland. Registration typically takes four to eight weeks, and the branch must appoint a representative authorised to act in Poland.

A sp. z o.o. subsidiary, by contrast, is incorporated as a standalone Polish company. Minimum share capital stands at PLN 5,000. The subsidiary has its own management board, its own tax identification number, and its own legal standing before Polish courts and the Polish Financial Supervision Authority (KNF) where regulated activities are involved. Shareholders' liability is capped at their contribution – a fundamental protection for the parent group.

Three structural differences matter most for group planning:

  • Liability – branch liability flows directly to the parent; subsidiary liability stays within the Polish entity
  • Tax treatment – a branch is taxed on income attributable to Polish activities; a subsidiary files its own corporate income tax return as a separate taxpayer
  • Exit – closing a branch is administratively simpler than liquidating a subsidiary, which requires a formal liquidation process of at least six months

Groups with significant contract risk or regulatory exposure in Poland almost always prefer the subsidiary. The branch suits short-term market testing or liaison functions where the parent is comfortable retaining full liability.

Who is affected – and what are the thresholds that matter?

The choice is not academic. Under Polish corporate legislation, board members of a sp. z o.o. face personal liability for company debts if insolvency filing is delayed beyond 30 days of the company becoming insolvent. That risk does not arise for a branch representative in the same way, but the parent entity bears the underlying exposure directly instead. Both paths carry liability – they simply allocate it differently.

We secured a restructuring outcome protecting assets worth over PLN 8m for a manufacturing client in the Mazowieckie region (autumn 2025) – a case where the original branch structure had created unexpected parent-level exposure that a subsidiary would have ring-fenced. The group had underestimated how quickly Polish contract liability could aggregate.

For groups considering the subsidiary route, due diligence Poland-side is essential before incorporation. Key thresholds include:

  • Share capital minimum of PLN 5,000 – low barrier, but articles of association must be carefully drafted
  • KRS registration timeline of two to four weeks for a sp. z o.o. via the online S24 system
  • Permanent establishment risk – a branch automatically creates a permanent establishment for corporate income tax purposes; a subsidiary may or may not, depending on activity
  • Transfer pricing documentation obligations arise once intra-group transactions exceed PLN 10m annually

Foreign investors from outside the European Union face additional restrictions. Non-EU nationals may not always set up company Poland structures in all legal forms without additional permits. EU-domiciled groups generally enjoy the same rights as Polish nationals under freedom of establishment principles. For a detailed comparison of share capital structures, see our analysis of sp. z o.o. vs SA decision matrix for Slovakia investors.

Our team obtained registration and full operational clearance for a technology group's Polish subsidiary in Lower Silesia within three weeks (spring 2026), avoiding a permanent establishment exposure that the branch alternative would have triggered immediately.

What should Poland groups do now?

Groups already operating through a branch should review their structure against current activity levels. If the Polish operation has grown beyond a liaison or representative function – signing contracts, employing staff, holding inventory – the branch may now create unintended tax and liability consequences. Conversion to a subsidiary is possible but requires careful sequencing to avoid gaps in operational continuity.

Board liability under Polish corporate law is a parallel concern for subsidiary structures. Directors who allow a subsidiary to trade while insolvent risk personal exposure for the full shortfall. For a detailed treatment of that exposure, see our guide on board liability under Polish corporate law – personal exposure.

Immediate action checklist for Poland groups:

  • Audit current Polish presence: branch, subsidiary, or unregistered activity
  • Confirm whether existing branch activity triggers permanent establishment under the applicable double tax treaty
  • Verify transfer pricing documentation is in place if intra-group flows exceed PLN 10m
  • Review articles of association of any existing sp. z o.o. for shareholder protection clauses
  • Assess M&A Poland pipeline – target due diligence should map the counterparty's structure before heads of terms are signed

For groups evaluating entry from the United Kingdom specifically, the post-Brexit framework introduces additional considerations around establishment rights. Our dedicated analysis covers the sp. z o.o. vs SA decision matrix for United Kingdom investors.

The window to restructure before a Polish tax audit or contract dispute arises is finite. A branch that has outgrown its original function – and has not been converted – is one of the more common structural oversights we encounter in M&A Poland due diligence. Waiting until a transaction or dispute surfaces the issue precludes the cleaner restructuring options available today.

Frequently asked questions

Q: Can a foreign group convert a branch into a subsidiary without interrupting operations in Poland?

A: Yes, conversion is possible but must be planned carefully. The process involves incorporating a new sp. z o.o., transferring contracts and assets, and deregistering the branch from the National Court Register. The typical timeline is two to four months. Contracts with Polish counterparties often require consent to assignment, so early engagement with key clients and suppliers is essential.

Q: How long does it take to register a sp. z o.o. in Poland, and what does it cost?

A: Registration through the online S24 system takes two to four weeks from submission of complete documents. Court fees amount to PLN 350 for the standard procedure. Legal and notarial costs vary depending on the complexity of the articles of association. A straightforward single-shareholder sp. z o.o. can be incorporated for under PLN 3,000 in total out-of-pocket costs, excluding share capital.

Q: Is it a misconception that a branch is always simpler to run than a subsidiary?

A: Yes – this is a common misunderstanding. A branch avoids incorporation formalities, but it does not reduce ongoing compliance obligations significantly. The branch must maintain separate accounting records for Polish activities, file Polish corporate income tax returns, and comply with local employment law. The parent also remains fully liable for all branch obligations. For groups with meaningful Polish activity, the subsidiary's liability ring-fence typically outweighs the modest administrative savings of the branch form.
