A Swedish group preparing to enter the Polish market faces a decision that shapes tax exposure, liability, and operational flexibility for years ahead. The choice between registering a branch (oddział) and incorporating a subsidiary (spółka z ograniczoną odpowiedzialnością, or sp. z o.o.) is not merely administrative. It determines how Polish corporate law, tax authorities, and the National Court Register (KRS) will treat your Polish presence from day one.

A branch in Poland is a legally dependent extension of the Swedish parent, carrying no separate legal personality and exposing the parent to unlimited liability for Polish operations. A subsidiary – typically a sp. z o.o. – is a distinct Polish legal entity, registered with the National Court Register (KRS), with liability capped at the share capital contributed. The registration timeline for a branch runs approximately 4–6 weeks; a sp. z o.o. can be incorporated digitally in as little as 24 hours via the S24 system, though full KRS registration takes 7–14 business days.

This alert outlines the structural differences, the compliance obligations each form triggers, and the immediate steps Swedish groups should take before committing to either structure. The analysis covers tax treatment, the Polish Financial Supervision Authority (KNF) requirements where relevant, and the practical pitfalls that surface most often in cross-border entry mandates.

What are the core structural differences between a branch and a subsidiary in Poland?

The branch carries no independent legal personality. It acts in the name of the Swedish parent, which means every contract, liability, and regulatory exposure flows directly to the parent's balance sheet. Polish commercial legislation requires the branch to register with the KRS and appoint a representative resident in Poland – a step that often surprises Swedish groups expecting a lighter touch. The branch must also mirror the parent's corporate name, appending the phrase "oddział w Polsce."

A sp. z o.o. is a separate Polish legal entity. Minimum share capital is PLN 5,000 – a threshold so low it rarely drives the decision. What matters more is that the subsidiary can contract, sue, and be sued in its own name. The parent's exposure is limited to its equity contribution, unless a court pierces the corporate veil under Polish corporate legislation. That protection is meaningful when entering markets with uncertain counterparty risk.

The branch structure suits Swedish groups testing the Polish market with a defined, time-limited project. The subsidiary suits groups planning sustained commercial activity, local hiring, or future M&A Poland transactions. Consider three scenarios:

  • A manufacturing group deploying a single project team for 18 months – branch may suffice.
  • An IT company building a Polish product hub with 20+ employees – subsidiary is the standard choice.
  • A Swedish investor acquiring a Polish target – the subsidiary is the required vehicle for post-acquisition integration.

We secured a smooth KRS registration for a Malmö-based technology group entering the Mazowieckie region (autumn 2025), resolving a representative-appointment dispute that had stalled the branch filing for six weeks. The lesson: branch registration is not simpler than incorporation – it is differently complex.

How does tax treatment differ – and where does the risk concentrate?

Tax treatment diverges sharply. A branch is taxed in Poland on income attributable to it as a permanent establishment (PE) under the Polish-Swedish double tax treaty. The branch does not file a separate corporate income tax (CIT) return as a legal entity – the parent does, allocating Polish-source income. This allocation exercise requires transfer-pricing-quality documentation even though no intercompany transaction formally exists. The Polish tax authority (Krajowa Administracja Skarbowa, KAS) has intensified scrutiny of PE profit attribution since 2024.

A subsidiary files its own CIT return. The standard CIT rate is 19%, with a reduced rate of 9% available to small taxpayers with annual revenue below EUR 2m. Dividends paid to the Swedish parent may qualify for exemption under the EU Parent-Subsidiary Directive, provided the parent holds at least 10% of the subsidiary's shares for an uninterrupted period of two years. Failure to satisfy the holding period forfeits the exemption – an irreversible consequence that cannot be corrected retroactively.

VAT registration obligations apply equally to both structures. A branch and a subsidiary must register for VAT before the first taxable transaction. There is no minimum-revenue threshold for foreign-entity branches. Personal liability of the branch representative for tax arrears is a real risk under Polish tax law – one that Swedish groups frequently underestimate during due diligence Poland exercises.

What immediate steps should Swedish groups take before registering?

The decision window matters. Polish registration procedures are sequential – errors in the initial KRS application extend timelines by 4–8 weeks and may require notarised corrections apostilled in Sweden. Acting before the operational launch date, rather than concurrently, avoids penalties for conducting business without registration. Operating in Poland without a registered presence exposes the Swedish parent to fines and, in regulated sectors, to KNF enforcement.

We obtained interim protection for a Swedish retail group's Polish assets exceeding EUR 3m in Lower Silesia (spring 2025), after a premature branch launch triggered a KAS inquiry. Early-stage structuring advice would have cost a fraction of the remediation.

Immediate action items for Swedish groups:

  • Confirm whether planned Polish activity constitutes a PE under the double tax treaty – this determines whether a branch creates unintended tax exposure.
  • Obtain a Polish tax identification number (NIP) and VAT registration before the first invoice.
  • Appoint a KRS representative with a Polish address at least 30 days before the intended launch.
  • Run a set up company Poland checklist covering AML, beneficial ownership (CRBR register), and employment law obligations.

Swedish groups with existing Polish suppliers or customers should also review whether prior commercial activity has already created a PE – a question that surfaces regularly in M&A Poland due diligence and can generate back-tax assessments covering up to five prior fiscal years. Comparing the sp. z o.o. vs SA decision matrix is also useful context; see our analysis at sp. z o.o. vs SA decision matrix for France investors.

Specific circumstances require specific advice. Choosing the wrong structure at entry stage precludes certain tax optimisations and may require a costly restructuring within 12–24 months.

Frequently asked questions

Q: Can a Swedish group convert a branch into a subsidiary later without tax consequences?

A: Conversion is possible but not tax-neutral. Polish tax law treats the transfer of branch assets to a newly incorporated sp. z o.o. as a taxable event unless specific restructuring relief conditions are met. The relief requires that the transaction is conducted for genuine commercial reasons and not primarily for tax avoidance – a standard that KAS examines closely. Planning the structure correctly at entry avoids this conversion cost entirely.

Q: How long does KRS registration take, and what documents are required from Sweden?

A: A sp. z o.o. incorporated via the S24 digital system can receive its KRS number within 7–14 business days. A branch registration typically takes 4–6 weeks. Both require certified translations of Swedish corporate documents (articles of association, extract from the Swedish Companies Registration Office) and, for the branch, a notarised power of attorney for the Polish representative. Apostille certification adds 5–10 business days in Sweden.

Q: Is a law firm Warsaw engagement necessary, or can Swedish in-house counsel manage the registration?

A: Polish KRS filings require documents in Polish and compliance with formal requirements that differ materially from Swedish company law. In-house teams regularly underestimate the beneficial ownership (CRBR) filing obligation, the AML declaration, and the VAT pre-registration steps. Errors trigger rejection notices that restart the timeline. Engaging a law firm Warsaw with KRS experience typically reduces total elapsed time and eliminates the risk of a defective registration that creates gaps in legal capacity.
