A Warsaw-based technology company receives a winding-up demand from its largest creditor. The management board has known for three months that the company's liabilities exceed its assets. No insolvency filing has been made. Under Polish insolvency law, each board member now faces personal liability for the company's unpaid debts – a consequence that cannot be reversed once the filing window closes.

Polish corporate law imposes direct personal liability on board members of a spółka z ograniczoną odpowiedzialnością (private limited liability company, sp. z o.o.) who fail to file for insolvency within 30 days of the company becoming insolvent. Liability extends to tax arrears, unpaid social security contributions, and unsatisfied creditor claims. The same framework applies to joint-stock companies registered in the National Court Register (KRS) and governs directors of foreign subsidiaries operating in Poland.

This page sets out the full liability framework: when personal exposure arises, which statutory defences are available, how cross-border structures complicate the picture, and what a sitting director should do today to reduce risk. The analysis draws on Polish corporate legislation, insolvency law, and tax enforcement provisions that together create overlapping – and sometimes unexpected – exposure for management board members.

When does board liability arise under Polish law?

Polish law creates liability through three distinct channels. First, corporate legislation makes board members of a sp. z o.o. personally liable for the company's obligations when enforcement against the company itself proves ineffective. Second, insolvency law triggers liability when the filing deadline is missed. Third, tax and social security statutes impose joint and several liability on board members for the company's public-law debts. All three channels operate simultaneously.

The insolvency filing deadline is 30 days from the moment the company becomes insolvent. Insolvency occurs when the company either stops meeting its monetary obligations as they fall due (liquidity insolvency) or when its total liabilities exceed the value of its assets for more than 24 months (balance-sheet insolvency). The 30-day clock runs from whichever trigger occurs first. Missing that deadline is the single most common source of personal exposure for Polish directors.

Tax liability works differently. The Polish Tax Ordinance holds board members jointly and severally liable for the company's tax arrears when the company cannot satisfy those arrears from its own assets. A director escapes this liability only by proving one of three things: the insolvency petition was filed on time; no fault can be attributed to the failure to file; or the director identified specific company assets sufficient to cover the debt. The Polish Financial Supervision Authority (KNF) may also impose separate regulatory sanctions on directors of supervised entities who breach governance obligations.

Social security contributions follow a parallel track. The Social Insurance Institution (ZUS) applies the same framework as the Tax Ordinance: board members become personally liable once the company defaults and enforcement fails. ZUS claims frequently surface two or three years after a company ceases trading, long after the relevant director has resigned. Resignation does not extinguish liability for obligations that arose during the director's tenure.

  • Liquidity insolvency: failure to pay two or more monetary obligations as they fall due
  • Balance-sheet insolvency: liabilities exceed assets for more than 24 consecutive months
  • Tax arrears: joint and several liability attaches once company enforcement fails
  • ZUS contributions: same framework, with claims surfacing years after resignation
  • Regulatory sanctions: KNF may act independently of civil or criminal proceedings

What defences can a director raise against personal liability?

Polish law provides three statutory defences, but each carries strict conditions. A director who filed the insolvency petition within the 30-day window, or who can show that no fault is attributable to the failure to file, or who identified specific recoverable company assets, may escape personal liability. In practice, the burden of proof rests entirely on the director. Courts apply these defences narrowly.

The "no fault" defence is the most frequently argued and the most frequently rejected. Polish courts have held that a director who was absent, ill, or excluded from management by a co-director cannot automatically rely on that exclusion as a defence. The director is expected to take active steps – including seeking legal advice, calling a shareholders' meeting, or resigning – within the 30-day window. Passive inaction does not qualify as absence of fault.

We secured a reversal of a personal liability assessment exceeding PLN 1.8m for a manufacturing client in the Mazowieckie region (autumn 2025). The director had resigned four months before the insolvency trigger but had identified specific receivables sufficient to cover the outstanding ZUS contributions. The Social Insurance Institution accepted the identified-assets defence after we provided a forensic cash-flow analysis prepared at the time of resignation.

The identified-assets defence requires precision. The director must point to assets that were specific, identifiable, and recoverable at the time the liability arose – not hypothetical future claims. A vague reference to "accounts receivable" without documentation of debtor identity, amount, and collectability will not satisfy the standard. Directors who anticipate financial difficulty should commission a formal asset inventory no later than the moment they first suspect insolvency.

Resignation strategy matters enormously. A director who resigns before the insolvency trigger arises escapes liability for obligations created after the resignation date, but remains exposed for all obligations that arose during tenure. The resignation must be filed with the KRS promptly. A resignation that sits in a drawer, unregistered, provides no protection whatsoever.

How do cross-border structures affect director exposure in Poland?

Foreign investors who set up company Poland operations through a sp. z o.o. subsidiary often appoint home-country executives as board members. Those executives become subject to Polish corporate liability rules from the moment of registration in the KRS – regardless of their nationality, residence, or the law governing their employment contract. Polish insolvency and tax liability provisions apply in full.

For a German investor entering the Polish market through a wholly owned subsidiary, the parent company's assumption that German GmbH law governs its Polish directors' obligations is a costly misconception. Polish law governs the subsidiary's board. The parent company itself may face liability if it exercised de facto control over the subsidiary's management decisions while allowing the subsidiary to slide into insolvency. Polish courts have increasingly examined economic unity arguments in cross-border groups.

Holding structures routed through Cyprus or other EU jurisdictions create additional complexity. Our analysis of branch versus subsidiary considerations – including liability implications for group directors – is set out in detail at branch vs subsidiary in Poland: comparison for Cyprus groups. The choice of entry vehicle directly affects which directors bear personal exposure and under which law.

Sanctions exposure adds a further layer. Board members of Polish subsidiaries that maintain commercial relationships with sanctioned counterparties face regulatory liability that is independent of corporate insolvency rules. The interaction between EU sanctions frameworks and Polish enforcement is examined at EU sanctions framework: impact on Polish businesses. A director who oversees a transaction later found to breach sanctions restrictions may face personal criminal liability under Polish law.

M&A Poland transactions involving the acquisition of a sp. z o.o. require careful due diligence Poland on the target board's historical liability exposure. Unpaid ZUS contributions and tax arrears from a previous board can surface after closing and, depending on deal structure, may create unexpected obligations for the acquiring entity's newly appointed directors. Thorough pre-acquisition review of KRS filings, ZUS accounts, and tax authority correspondence is essential.

What practical pitfalls do directors most commonly overlook?

The most frequent pitfall is miscalculating the 30-day insolvency filing window. Directors often measure the window from the date a formal demand letter arrives, rather than from the earlier date on which the company objectively stopped meeting its obligations. Polish courts assess the trigger date retrospectively, using financial records. A director who believed the window had not yet started may find that it closed weeks before the filing was made.

A second common error involves multi-member boards. Where a sp. z o.o. has three or four board members, each director assumes that one of the others is monitoring solvency. No formal allocation of responsibility eliminates personal liability. Polish corporate law holds every board member individually responsible for the insolvency filing obligation. Internal delegation to a CFO or a co-director is not a defence recognised by Polish courts.

We obtained interim measures protecting assets worth over EUR 3m for a foreign investor's Polish subsidiary in Lower Silesia (spring 2026). The client's newly appointed CEO had discovered that the outgoing board had failed to file for insolvency within the statutory window. Swift action – including a criminal complaint against the former directors and an emergency KRS filing – prevented the client from inheriting personal exposure.

A third pitfall is ignoring the interaction between corporate liability and personal tax exposure. When a director is also a shareholder and receives dividend payments or shareholder loans during a period of concealed insolvency, those transactions may be challenged as fraudulent preference under insolvency law. The director then faces both personal liability for the company's debts and a claim for repayment of the distributions received. The financial consequences compound rapidly.

  • Confirm the solvency trigger date from financial records, not from demand letters
  • Document board-level solvency monitoring at every meeting
  • Register resignations with the KRS immediately – not after the next board meeting
  • Audit shareholder loans and dividend payments during any period of financial stress

The law firm Warsaw practitioners at KORDECKI & Partners have observed that directors of foreign-owned subsidiaries are disproportionately affected by these pitfalls. The combination of unfamiliar Polish procedural rules, language barriers, and reliance on group-level legal teams that lack Polish-specific expertise creates a dangerous gap. Closing that gap before a crisis arises is far less expensive than defending personal liability proceedings after the fact.

What should directors do now? A self-assessment checklist

Every sitting board member of a Polish company should complete a solvency self-assessment at least once per quarter. The assessment requires access to current balance-sheet data, aged creditor listings, and a cash-flow forecast for the next 90 days. If any of the following conditions is present, the 30-day filing window may already be running.

  • Two or more monetary obligations have been unpaid for more than 30 days
  • Total liabilities exceed total assets on the most recent balance sheet
  • The company has deferred ZUS or tax payments without a formal instalment agreement
  • A creditor has obtained an enforcement title against the company in the past 12 months
  • The company has missed payroll or reduced salaries due to cash constraints

Directors should also verify their KRS registration status. A director whose appointment has lapsed – because the term expired and no renewal resolution was passed – may still be treated as a de facto director by tax authorities and insolvency courts. The KRS records the formal position, but Polish law can pierce that record where actual management conduct is inconsistent with the registered status.

Internal governance documentation is a practical shield. Board resolutions that explicitly address solvency monitoring, identify the person responsible for financial oversight, and record the board's assessment of the company's financial position create a contemporaneous record that can support a "no fault" defence. Resolutions drafted after a crisis begins carry far less evidentiary weight than those prepared as a matter of routine governance.

For companies operating in multiple jurisdictions, the Polish board's obligations do not diminish simply because group-level decisions are made elsewhere. If your group's M&A Poland strategy involves Polish entities with active boards, those boards must function independently on Polish-law compliance matters. KORDECKI & Partners advises on structuring board governance for cross-border groups, including clients active in Spain – further detail is available at our corporate M&A practice for Spain.

Frequently asked questions

Q: Can a director escape liability by resigning from the board before the company becomes insolvent?

A: Resignation before the insolvency trigger date eliminates exposure for obligations arising after resignation. However, the director remains fully liable for tax arrears, ZUS contributions, and creditor claims that arose during the period of tenure. The resignation must be registered with the National Court Register without delay – an unregistered resignation has no legal effect against third parties, including the Tax Office and ZUS. Directors considering resignation should obtain a written legal opinion on the timing before acting.

Q: How long does a personal liability proceeding typically take, and what are the likely costs?

A: A ZUS or tax authority liability assessment is typically issued within 12 to 24 months of the company's enforcement failure. The director then has 14 days to appeal to the relevant administrative authority, followed by a further appeal to the administrative court (WSA) and, if necessary, the Supreme Administrative Court (NSA). The full cycle, from first assessment to final judgment, commonly takes three to five years. Legal costs depend on the amount in dispute and the complexity of the factual record, but directors should budget for professional representation from the moment the first assessment is received.

Q: Does the 30-day insolvency filing deadline apply to foreign directors of Polish subsidiaries in the same way as to Polish nationals?

A: Yes. Polish insolvency law applies to all members of the management board of a Polish-registered company, irrespective of nationality or residence. A German, French, or Ukrainian national serving on the board of a sp. z o.o. is subject to exactly the same 30-day filing obligation and the same personal liability consequences for breach. Foreign directors who are unfamiliar with Polish insolvency procedure should seek local legal advice immediately upon joining a Polish board, and should ensure they receive regular financial reporting in a language they can assess.
