Corporate governance for Poland subsidiaries

A German parent company establishes a Polish subsidiary, appoints a local management board, and assumes the governance frameworks used at home will transfer automatically. Six months later, the subsidiary misses a mandatory filing at the National Court Register (KRS), the management board acts without a required shareholder resolution, and the parent discovers it has no contractual mechanism to recover the resulting loss. This pattern repeats across industries and entry structures. It is avoidable.

Corporate governance for a Polish subsidiary is governed primarily by the Kodeks spółek handlowych (Commercial Companies Code, KSH), which sets mandatory rules for board composition, decision-making authority, and shareholder oversight. A spółka z ograniczoną odpowiedzialnością (private limited liability company, sp. z o.o.) must register any change to its management board at the KRS within seven days of the resolution. Failure to maintain compliant governance exposes board members to personal liability for company obligations and can invalidate material corporate decisions.

This guide covers four areas: the structural building blocks of Polish subsidiary governance, the decision-making framework and reserved matters, common mistakes that foreign parents make in the first 24 months of operation, and a practical checklist for bringing an existing subsidiary into compliance. Each section includes at least one concrete figure and a scenario drawn from our practice.

What does the KSH require for a Polish sp. z o.o. governance structure?

The Commercial Companies Code sets a baseline that every subsidiary must meet, regardless of what the parent's group policy says. A sp. z o.o. requires at least one management board member (zarząd), who holds full executive authority. A supervisory board (rada nadzorcza) is optional unless the share capital exceeds PLN 500,000 and the company has more than 25 shareholders – in that case, one is mandatory. Most foreign-owned subsidiaries fall below that threshold but choose to install a supervisory board voluntarily for group oversight purposes.

The KRS, operated by the Polish court system, is the public register of legal entities. Every board appointment, resignation, and change of registered address must be filed there. The filing window is seven days from the triggering resolution. The Polish Financial Supervision Authority (KNF) becomes relevant where the subsidiary operates in regulated sectors – financial services, insurance, or capital markets – and imposes additional fit-and-proper requirements on board members. The Office of Competition and Consumer Protection (UOKiK) matters when the subsidiary is party to transactions that may require merger control clearance.

Foreign parents frequently underestimate the formality of Polish corporate documents. A board resolution must be recorded in a written protocol signed by all members present. A shareholders' resolution requires a notarised deed if it amends the articles of association. Both documents must be kept in the company's registered office and made available for inspection. Missing even one protocol can complicate a future due diligence Poland process and delay a planned exit.

Minimum one management board member; no maximum set by statute
Supervisory board mandatory above PLN 500,000 capital and 25 shareholders
KRS filing deadline: seven days from resolution
Notarial form required for articles of association amendments
Board meeting protocols must be signed and retained on file

We helped a Mazowieckie-region IT subsidiary of a Dutch group reconstruct three years of missing board protocols and regularise its KRS filings ahead of a planned acquisition (autumn 2024). The process took eight weeks and cost a fraction of what a failed transaction would have.

How should reserved matters and shareholder authority be structured?

The KSH grants shareholders of a sp. z o.o. a defined set of reserved matters – decisions that require a shareholder resolution regardless of what the management board prefers. These include approval of the annual financial statements, profit distribution, disposal of the enterprise or a significant part of it, and amendment of the articles of association. Beyond this statutory floor, parents routinely expand reserved matters through the articles themselves or through a separate shareholders' agreement.

A well-drafted reserved matters list is the primary governance tool available to a foreign parent. Typical additions include capital expenditure above a set threshold (commonly EUR 100,000 for mid-size subsidiaries), entering into related-party transactions, granting or receiving loans above a defined amount, and hiring or dismissing the CEO. Each threshold should be expressed in PLN to avoid currency disputes. The articles of association can also require a qualified majority – 75% or even unanimity – for sensitive decisions, which protects minority shareholders in joint ventures.

One structural choice deserves attention: the difference between a single-tier and a two-tier model. Polish law defaults to a single-tier structure (management board only). Adding a supervisory board creates a two-tier model closer to German or Dutch practice, which many European parents find familiar. The supervisory board can be granted approval rights over the reserved matters list, making it an active governance body rather than a formality. However, supervisory board members cannot simultaneously serve on the management board – a rule the KSH enforces strictly.

For a practical comparison of how these structures interact with group-level reporting lines, see our analysis of branch vs subsidiary in Poland, which addresses capital structure choices relevant to the same governance decisions.

What are the most common governance mistakes in the first 24 months?

The first two years of a Polish subsidiary's life produce a predictable set of errors. Each carries a specific legal consequence. Understanding them in advance is cheaper than remedying them after a KAS tax audit or a shareholder dispute.

The most frequent mistake is failing to update the KRS promptly. A board member who resigns but remains on the register continues to bear legal responsibility for the company's acts. Personal liability under Polish corporate legislation extends to unpaid taxes and social security contributions, with no cap. The seven-day filing window is short. Parent companies that route all KRS filings through their group legal team in another jurisdiction routinely miss it.

The second common error is operating under an outdated or generic articles of association. Many subsidiaries are set up using a standard template available through the online S24 registration system. That template contains no reserved matters, no conflict-of-interest rules, and no provisions for deadlock resolution. It is adequate for registration. It is inadequate for governance. Amending the articles requires a notarised shareholder resolution and a KRS update – a process that takes four to six weeks from instruction to registration.

Third: ignoring the requirement for annual shareholder meetings. The KSH requires an ordinary shareholder meeting within six months of the end of each financial year. Where the financial year follows the calendar year, the deadline is 30 June. Missing this meeting does not automatically invalidate the financial statements, but it exposes the management board to liability and complicates the company's standing in subsequent M&A Poland transactions.

We identified a pattern of undocumented shareholder instructions given verbally to the management board of a manufacturing subsidiary in Silesia (spring 2025). The parent had treated the subsidiary as an internal department rather than a separate legal entity. Regularising the governance structure required a full internal review – a process described in our guide on internal investigations methodology for Polish companies.

A bridge note for foreign buyers: governance defects discovered during due diligence are treated as price-adjustment items or deal-breakers. For an overview of what acquirers look for, see our article on red flags in Polish M&A for United Kingdom buyers.

How do three business scenarios illustrate the governance framework in practice?

Abstract rules become clearer through concrete situations. Three scenarios – manufacturing, IT services, and a foreign investor entering through acquisition – each expose a distinct governance pressure point.

Manufacturing subsidiary (Wielkopolska region). A German parent operates a production facility through a Polish sp. z o.o. The management board consists of two Polish nationals appointed by the parent. The articles contain no reserved matters beyond the statutory minimum. The board enters into a five-year supply contract worth EUR 2.4m without seeking parental approval. Under Polish law, the contract is valid. The parent has no legal recourse against the counterparty. Its only remedy is against the board members – and only if it can show the decision breached a fiduciary duty. A reserved matters clause covering contracts above EUR 200,000 would have prevented this entirely.

IT services subsidiary (Mazowieckie region). A British group sets up a Polish sp. z o.o. to employ software developers and bill the parent for services. The sole board member is also the group's CFO, based in London. He resigns from the Polish board without triggering a KRS update. For 11 weeks, the company has no registered board member. During that period, the company signs two employment contracts and a lease. Polish law treats those acts as valid but holds the person who acted without authority personally liable for any resulting loss. The gap in the KRS record also triggers a compliance flag during a subsequent set up company Poland review by a potential acquirer.

Foreign investor entering through acquisition. A Dutch holding company acquires 100% of a Polish sp. z o.o. through a share purchase. The due diligence Poland review identifies three years of missing annual meeting resolutions and an undocumented shareholder loan of PLN 800,000. The buyer conditions closing on a governance clean-up: updated articles, retrospective resolutions where legally permissible, and a new shareholders' agreement. The clean-up adds six weeks to the timeline. A pre-acquisition governance audit would have surfaced these issues earlier and allowed the seller to remedy them before the process began.

What should a compliance checklist for an existing subsidiary include?

Bringing an existing subsidiary into governance compliance is a structured process. It does not require a full legal overhaul in every case. It does require a methodical review against the KSH baseline and the company's own articles of association. The following checklist applies to any sp. z o.o. with a foreign parent and at least 12 months of operating history.

Verify that all current board members are correctly registered at the KRS and that no former members remain on the register
Confirm that the articles of association contain a reserved matters list aligned with the parent's group policy and expressed in PLN thresholds
Check that annual shareholder meeting resolutions exist for each completed financial year, with the 30 June deadline respected
Review all related-party transactions for the past three years to confirm they were authorised by shareholder resolution where required
Ensure board meeting protocols are complete, signed, and stored at the registered office

Each item on this list is a potential deal-breaker in an M&A process. Each is also remediable before a transaction begins, provided the parent acts before a buyer's advisers arrive. The cost of remediation is almost always lower than the cost of a price reduction or a failed deal.

A specific governance risk worth flagging: where the management board has fewer than two members, the company cannot validly represent itself in disputes against the sole board member personally. Polish corporate legislation requires a supervisory board or a proxy appointed by the shareholder meeting to act in that situation. Many subsidiaries lack both.

The specific situation of your subsidiary requires tailored advice. Governance defects that appear minor in isolation can become irreversible liabilities once a transaction or a regulatory review is underway.

Frequently asked questions

Q: How long does it take to amend the articles of association of a Polish sp. z o.o. and update the KRS?

A: The shareholder resolution amending the articles must be made in notarial form. Scheduling a notary appointment typically takes one to two weeks. The KRS registration of the amendment takes a further three to five weeks under current court processing times. The total timeline from instruction to completed registration is therefore four to six weeks. Acting before a transaction or regulatory deadline is essential – the KRS does not offer expedited processing for commercial reasons.

Q: Is a supervisory board required for a typical foreign-owned sp. z o.o.?

A: Not automatically. Under Polish corporate legislation, a supervisory board is mandatory only where share capital exceeds PLN 500,000 and the number of shareholders exceeds 25. Most single-parent foreign subsidiaries fall below both thresholds. However, many European parents install a supervisory board voluntarily to replicate the two-tier model they use at home. A common misconception is that a supervisory board provides an additional layer of protection against management board liability – in fact, supervisory board members can themselves incur liability if they approve decisions that breach the law or the articles.

Q: Can a foreign parent give binding instructions directly to the management board of its Polish subsidiary?

A: This is one of the most misunderstood points of Polish corporate governance. The management board of a sp. z o.o. is legally obliged to act in the interests of the company, not the parent. Verbal or informal instructions from the parent have no binding legal force and do not transfer liability. The correct mechanism is a reserved matters clause in the articles or a shareholders' resolution. Instructions given outside these channels may expose the management board to personal liability if they follow them and the company suffers a loss. Structuring the governance framework correctly – through the articles and a shareholders' agreement – is the only reliable way for a parent to maintain control.
