A Madrid-based industrial group decides to expand into Poland. The commercial team wants speed. The CFO wants cost control. The legal department wants to know: branch or subsidiary? On paper, the choice looks simple. In practice, the two structures carry different tax profiles, liability exposures, and administrative burdens that will shape the group's Polish operations for years.

Spanish groups entering Poland may register either a branch (oddział) of the Spanish parent or a separate legal entity – most commonly a limited liability company (spółka z ograniczoną odpowiedzialnością, sp. z o.o.). A branch is not a separate legal person: the Spanish parent bears unlimited liability for its obligations. An sp. z o.o. is an independent legal entity with liability capped at the share capital, minimum PLN 5,000. Registration of both structures is handled by the National Court Register (Krajowy Rejestr Sądowy, KRS), and the choice between them determines the group's tax position, governance obligations, and exit options from day one.

This page compares the two structures across the dimensions that matter most to Spanish groups: formation timeline, ongoing compliance, tax treatment, liability allocation, and strategic flexibility. It also flags the pitfalls that most often catch foreign investors off guard during the first 12 months of Polish operations.

What does a branch in Poland actually mean for a Spanish parent?

A branch is a registered presence of the Spanish parent, not a new company. It carries out the parent's business in Poland under the parent's name. The parent is directly and fully liable for every obligation the branch incurs – commercial, tax, and employment. There is no capital buffer. That single fact drives most of the risk analysis.

Registration with the KRS takes roughly four to eight weeks from the submission of a complete application. The branch must appoint a representative resident in Poland (the pełnomocnik oddziału). Required documents include a certified copy of the Spanish parent's deed of incorporation, a certificate of good standing from the Spanish Mercantile Registry (Registro Mercantil), and a Polish-language translation of each document prepared by a sworn translator. The KRS filing fee is PLN 500 for registration and PLN 100 for announcement in the Court and Commercial Gazette (Monitor Sądowy i Gospodarczy).

A branch must keep separate accounting records in Polish, comply with Polish bookkeeping standards, and file annual financial statements with the KRS. It registers for VAT with the relevant tax office and obtains a NIP (tax identification number). Corporate income tax (CIT) applies only to profits attributable to the Polish branch – a concept that requires careful transfer pricing documentation when the branch and parent share functions or costs. The Polish tax authority (Krajowa Administracja Skarbowa, KAS) pays close attention to attribution of profits to permanent establishments.

The key advantage of a branch is operational simplicity at the group level. There are no shareholders' meetings, no share capital requirements, and no dividend formalities. Profits flow directly to the Spanish parent. For a group testing the Polish market with a defined project or a time-limited contract, the branch can be wound up without the full liquidation procedure required for an sp. z o.o. – though dissolution still requires a KRS filing and a formal closure of tax registrations.

We secured a successful KRS registration and full tax onboarding for a branch of a Spanish engineering group in Mazowieckie (spring 2025), completing the process in six weeks from receipt of the apostilled Spanish documents.

When does a subsidiary become the better choice for Spain groups?

An sp. z o.o. is the default entry vehicle for most foreign investors in Poland. Minimum share capital is PLN 5,000, divided into shares with a nominal value of at least PLN 50 each. The company is incorporated before a Polish notary, registered with the KRS, and becomes a separate taxpayer from the moment of registration. Formation typically takes two to four weeks when using the standard notarial route, or as little as one to two business days via the S24 online system for straightforward structures.

Liability is the central argument for the subsidiary. The Spanish parent's exposure is limited to its equity contribution. Polish law does not pierce the corporate veil except in narrow circumstances – primarily where the subsidiary's board fails to file for insolvency within 30 days of the company becoming insolvent, triggering personal liability of directors. The parent itself remains protected. For groups with significant contract exposure, product liability risk, or regulated activity in Poland, this separation is not a formality – it is the foundation of the group's risk architecture.

Tax treatment differs meaningfully. An sp. z o.o. is a separate CIT taxpayer at 19% (or 9% for small taxpayers with revenue below EUR 2 million in the prior year). Dividends paid to a Spanish parent benefit from the EU Parent-Subsidiary Directive, which eliminates withholding tax on qualifying distributions where the parent holds at least 10% of the subsidiary's shares for an uninterrupted period of two years. Interest and royalty payments also benefit from the EU Interest and Royalties Directive. These treaty benefits do not apply to a branch, because a branch has no separate legal personality through which distributions are made.

Governance adds cost. An sp. z o.o. requires at least one management board member, annual financial statements filed with the KRS, and – above certain thresholds – a statutory audit. The company must maintain a share register, hold annual shareholders' meetings, and comply with the Kodeks spółek handlowych (Commercial Companies Code, KSH). For a group accustomed to Spanish sociedad de responsabilidad limitada (S.L.) governance, the KSH requirements are broadly familiar, though the procedural details differ.

How do tax and transfer pricing rules differ between the two structures?

Tax is where the branch-versus-subsidiary choice produces the sharpest practical differences. Both structures pay Polish CIT, but the mechanics – and the compliance burden – diverge significantly. Getting this wrong in year one creates problems that take years to unwind.

A branch is treated as a permanent establishment (PE) of the Spanish parent under the Poland-Spain Double Taxation Treaty. Polish CIT applies to profits attributable to the PE. Attribution requires the branch to be treated as a hypothetically independent enterprise, applying arm's length pricing to transactions with the head office. This means transfer pricing documentation is mandatory even for internal cost allocations – shared services, management fees, IP licences, and group financing. The KAS has intensified PE audits since 2023, with particular focus on Spanish, German, and French groups operating through branches in Mazowieckie and Silesia.

An sp. z o.o. is a separate taxpayer. Transfer pricing rules still apply to transactions with the Spanish parent, but the framework is cleaner: the subsidiary is an identifiable legal entity with its own profit and loss, and the arm's length analysis is straightforward. The 9% reduced CIT rate for small taxpayers – those with annual revenue below EUR 2 million – can materially reduce the effective tax burden in the first two to three years of operation, when revenue ramps slowly. A branch cannot access this rate because it is not a separate taxpayer.

VAT registration is required for both structures from the first taxable transaction in Poland. There is no registration threshold for non-established entities. A branch and an sp. z o.o. both obtain a Polish VAT number and file JPK_VAT reports monthly. The Polish VAT group regime, available since 2023, is open only to separate legal entities – so a branch cannot join a Polish VAT group that the wider group might establish. For groups with multiple Polish entities, this is a relevant structural consideration.

What are the main compliance pitfalls for Spanish groups in Poland?

Experience across dozens of Spanish-group matters in Poland reveals a consistent pattern of avoidable mistakes. Most arise not from ignorance of Polish law but from assuming that Spanish S.L. or S.A. governance translates directly. It does not. Polish corporate law has its own logic, and the KSH is unforgiving of procedural shortcuts.

The most common pitfall for branches is inadequate documentation of the representative's authority. The branch representative (pełnomocnik oddziału) acts under a power of attorney granted by the Spanish parent's competent body. If that body is a collective management organ – a board of directors (consejo de administración) – Polish law requires evidence that the board resolution authorising the power of attorney was adopted in accordance with the parent's statutes. KRS examiners routinely reject applications where this chain of authority is not documented in full.

For subsidiaries, the most frequent error is under-capitalisation relative to the planned activity. PLN 5,000 is the statutory minimum, but it is not a commercial minimum. A subsidiary bidding for public contracts, entering long-term leases, or seeking bank financing will be assessed on its actual equity base. Groups that incorporate with PLN 5,000 and then need to raise equity six months later face a notarial amendment, a KRS update, and a delay that damages commercial credibility.

Both structures face compliance risk around beneficial ownership registration. Poland's Central Register of Beneficial Owners (Centralny Rejestr Beneficjentów Rzeczywistych, CRBR) requires disclosure of ultimate beneficial owners within seven days of registration and within seven days of any change. Failure to register on time carries a fine of up to PLN 1,000,000. Spanish groups with complex holding structures – particularly those involving trusts or foundations at the ultimate ownership level – should conduct due diligence on the Polish CRBR disclosure requirements before registration.

We assisted a Spanish retail group in restructuring its Polish sp. z o.o. after a CRBR non-compliance was identified during a KAS audit in Małopolska (autumn 2024), avoiding the maximum penalty through voluntary disclosure and prompt remediation.

Spanish groups considering cross-border structures should also review our analysis of how Cyprus-based groups approach the same branch-versus-subsidiary choice, as the EU-law framework is shared but the tax treaty terms differ.

What should a Spanish group prepare before registering in Poland?

Preparation reduces formation time and eliminates the most common causes of KRS rejection. The checklist below applies to both branches and subsidiaries, with structure-specific items noted. Allow four to six weeks to gather and apostille Spanish documents before the Polish registration process begins.

  • Apostilled Spanish corporate documents – deed of incorporation (escritura de constitución), current statutes, and a certificate of good standing from the Mercantile Registry, each apostilled under the Hague Convention and translated by a Polish sworn translator.
  • Board resolution authorising Polish registration – for a branch, authorising the representative and defining the scope of activity; for a subsidiary, authorising the shareholder to sign the notarial deed and subscribe shares.
  • Identification of the Polish representative or management board member – a natural person with a Polish PESEL number (or a NIP, for non-residents) is required; KRS registration cannot proceed without this.
  • Beneficial ownership analysis – map the full ownership chain to the ultimate beneficial owner(s) before registration; CRBR disclosure must be filed within seven days of KRS registration.
  • Tax structure review – confirm the CIT rate applicable (19% or 9%), VAT registration obligations, and transfer pricing documentation requirements before the first commercial transaction.

For groups with M&A Poland ambitions – acquiring an existing Polish business rather than greenfield registration – the preparation list expands to include due diligence Poland on the target's KRS filings, tax history, employment contracts, and real estate encumbrances. A set up company Poland approach and an acquisition approach have different timelines and risk profiles, and the choice between them deserves separate analysis.

Every Spanish group entering Poland will face commercial disputes at some point. Understanding how Polish courts and arbitration tribunals handle cross-border claims – and how Spanish judgments are enforced in Poland – is part of the entry planning. Our dedicated resource on dispute resolution for Spanish companies doing business in Poland addresses these questions directly.

The specific structure your group chooses will shape its Polish tax position, liability exposure, and exit options for the next five to ten years. These consequences are not easily reversed once the first commercial contracts are signed. To receive an expert assessment of your group's entry structure options, contact info@kordeckipartners.com.

Frequently asked questions

Q: Can a Spanish group convert a branch into an sp. z o.o. after registration?

A: Polish law does not provide a direct conversion procedure from a branch to an sp. z o.o. In practice, the group must incorporate a new sp. z o.o., transfer the branch's assets and contracts to the new entity, and then deregister the branch. This process takes a minimum of three to four months and may trigger VAT and stamp duty on asset transfers. Groups that anticipate growth should therefore choose the subsidiary structure from the outset rather than planning a later conversion.

Q: How long does KRS registration take, and what are the costs?

A: For an sp. z o.o. incorporated via notarial deed, KRS registration typically takes two to three weeks from submission of a complete application. The S24 online route can reduce this to one to two business days for straightforward structures. For a branch, allow four to eight weeks. Court fees are PLN 500 for registration and PLN 100 for gazette publication. Notarial fees for an sp. z o.o. incorporation depend on share capital but typically range from PLN 1,000 to PLN 3,000. Legal and translation fees are additional and vary by complexity.

Q: Does a Spanish parent need a Polish resident director for an sp. z o.o.?

A: No. The Commercial Companies Code does not require management board members of an sp. z o.o. to be Polish residents or Polish nationals. A Spanish national residing in Spain can serve as the sole management board member. However, the board member must obtain a Polish NIP (tax identification number) for KRS registration purposes. For day-to-day operations – signing contracts, managing employees, dealing with Polish authorities – a local point of contact is strongly advisable, even if not legally required.
