If enforcement against a Polish limited liability company (sp. z o.o.) proves unsuccessful, the members of its management board become personally and jointly liable for the company’s outstanding obligations — with no upper limit on the amount. This is the core rule of Article 299 § 1 of the Polish Commercial Companies Code (KSH). The liability is personal, subsidiary, and unlimited in value. A director can escape it, but only by proving one of three statutory defences under Article 299 § 2 KSH.
What is liability under Article 299 KSH?
Article 299 KSH is a creditor-protection mechanism. It allows creditors to pursue payment directly from board members when the company itself has no assets to cover its debts. The legal basis is compensatory: a director is liable for the damage suffered by the creditor as a result of the board’s failure to file for insolvency in time.
This is not an automatic assumption of the company’s debt. The creditor must establish two things: that the company owes them a debt (evidenced by an enforceable title — a court judgment or payment order) and that enforcement against the company has failed (typically a court bailiff’s order terminating enforcement). The creditor does not need to prove fault on the part of the directors — the law presumes a causal link between the board’s inaction and the creditor’s loss.
Key features of Article 299 KSH liability
- Personal — the director’s entire private estate is at risk: real estate, vehicles, savings, salary.
- Joint and several — the creditor may sue one, some, or all board members. Each is liable for the full amount.
- Subsidiary — the creditor can only pursue directors after demonstrating that enforcement against the company has failed.
- Unlimited in value — covers the full unpaid amount, including interest and enforcement costs.
Which debts trigger director liability?
Directors are liable for all monetary obligations of the company that the creditor could not recover from company assets. The source of the debt is irrelevant — it may be unpaid invoices, tax arrears, social security contributions, contractual penalties, damages, or court costs.
Liability covers obligations that existed while the director held office. In our experience at Progress Holding, creditors most frequently pursue directors for unpaid trade invoices and tax arrears owed to the Polish tax authority.
Public-law obligations
Alongside Article 299 KSH, Article 116 of the Polish Tax Ordinance operates in parallel. On that basis, a director can be held personally liable for the company’s tax arrears — corporate income tax (CIT), VAT, and payroll income tax (PIT) — under the same conditions: failed enforcement against the company and no applicable exculpatory grounds. The same logic applies to unpaid social security (ZUS) contributions under the Social Insurance System Act.
When does liability arise — and who is affected?
Article 299 KSH applies to any person who served as a board member at the time the company’s obligation arose. What matters is the date of formal appointment by shareholders’ resolution — not the date of registration in the National Court Register (KRS). KRS registration is declaratory, not constitutive.
Resignation does not end liability
This is one of the most common misconceptions we encounter at Progress Holding. Resigning from the board does not close the book on liability for obligations that arose during the director’s term. If a debt came into existence while the person was on the board, they remain liable for that debt even after leaving — provided that the grounds for filing insolvency existed while they were still in office.
Being a “figurehead” director offers no protection
An internal division of duties within the board has no bearing on Article 299 KSH liability. A director who “did not handle finances” is just as exposed as one who did. Lack of access to financial records is not a valid defence — Polish law imposes on every board member a duty to monitor the company’s financial health.
How to escape liability — the 3 defences under Article 299 § 2 KSH
A director can avoid liability by proving at least one of three statutory defences. The burden of proof rests entirely on the director.
Defence 1: Insolvency or restructuring petition filed in time
This is the most common and most effective line of defence. The director must show that an insolvency petition was filed, or that restructuring proceedings were opened or an arrangement approved, within the statutory time limit.
The deadline is 30 days from the date on which grounds for insolvency arose — that is, the date on which the company became insolvent (Article 21(1) of the Polish Insolvency Law). A company is insolvent when it has lost the ability to pay its due monetary obligations (delay exceeding 3 months) or when its liabilities exceed the value of its assets (and this condition has persisted for more than 24 months).
The petition need not have been filed by the director being sued — it is sufficient that another board member or another authorised person filed it.
Defence 2: No fault in failing to file
The director must prove that the failure to file for insolvency occurred without their fault — due to circumstances beyond their control. Examples: serious illness preventing the performance of duties, hospitalisation, force majeure. This is a difficult defence to make out. Lack of business or financial education, ignorance of the law, or an internal division of duties are not recognised as grounds for absence of fault.
Defence 3: No loss to the creditor
The director shows that even if the insolvency petition had been filed on time, the creditor would still not have been satisfied — because the company had no distributable assets. This requires detailed financial analysis and typically an expert opinion.
| Defence | What the director must prove | Practical effectiveness |
|---|---|---|
| Insolvency / restructuring petition in time | Petition filed within 30 days of insolvency | Highest — most frequently used |
| No fault in failing to file | Objectively impossible to act (illness, force majeure) | Low — narrow range of accepted grounds |
| No loss to the creditor | Creditor would not have been satisfied even with timely petition | Medium — requires expert opinion |
What did the Constitutional Court ruling of 12 April 2023 change?
Poland’s Constitutional Tribunal (Trybunał Konstytucyjny), in its ruling of 12 April 2023 (case ref. P 5/19), held that Article 299 § 1 and § 2 KSH is partially incompatible with the Polish Constitution. The incompatibility lies in the fact that the provision did not allow a former director to challenge the very existence of a debt established by a court judgment issued after they had left the board.
In practical terms: if the judgment ordering the company to pay was issued in proceedings commenced after the defendant had already ceased to be a director, that former director can now argue in their defence that the underlying debt does not actually exist. Prior to this ruling, such a defence was unavailable — the court was bound by the final judgment against the company.
This is a significant development for all former CEOs and board members. The ruling does not abolish Article 299 KSH liability, but it expands the available defences in specific circumstances.
What is the limitation period for claims under Article 299 KSH?
Claims under Article 299 KSH are time-barred after 3 years. Since director liability is tortious in nature (damages for a wrongful act), the limitation period under Article 4421 of the Civil Code applies.
The limitation period begins on the date the creditor learned of the unsuccessful enforcement against the company — typically the date the bailiff’s order terminating enforcement was served. In any event, the claim extinguishes no later than 10 years from the event giving rise to the loss.
In our work at Progress Holding, we regularly see creditors delay suing directors, hoping for voluntary payment. This is a mistake — the 3-year clock runs regardless of negotiations. A director can raise a limitation defence in court.
How to protect yourself against Article 299 KSH liability
The most effective protection is prevention: continuous monitoring of the company’s financial position and immediate action at the first signs of insolvency. At Progress Holding, we recommend the following steps to our clients.
Ongoing financial monitoring
The board must regularly review the balance sheet, cash flows, and the timeliness of payment obligations. If the company starts missing payments — delays exceeding 3 months, or total liabilities approaching or exceeding total assets — these are warning signals that must be acted on.
The 30-day deadline — do not wait
From the moment insolvency arises, you have 30 days to file an insolvency petition. This deadline is absolute. Every day of delay increases your personal liability exposure. If the company cannot recover — file. If there is a realistic chance of turnaround — consider formal restructuring, which also qualifies as an exculpatory ground.
Document your decisions
Keep board meeting minutes, financial reports, correspondence with your accountant, and professional advisers’ opinions. In litigation under Article 299 KSH, evidence determines the outcome. A director who can demonstrate they actively responded to the company’s financial difficulties is in a far stronger position.
D&O insurance
Directors and Officers (D&O) liability insurance covers the cost of legal defence and any damages awarded to creditors. For companies with annual turnover above PLN 1–2 million, a D&O policy is a sound investment.
The most common board mistakes we see at Progress Holding
Based on our analysis of over 200 sp. z o.o. companies whose accounting we manage at Progress Holding, we have identified three recurring patterns that lead to director liability problems.
Mistake 1 — ignoring tax arrears. The company stops paying VAT or corporate income tax instalments for 3–4 months, expecting incoming client payments to cover everything. The Polish tax authority does not wait — it initiates enforcement, and when that fails, issues a decision on director liability under Article 116 of the Tax Ordinance. We see this particularly often in single-member sp. z o.o. companies run by foreign founders who do not track Polish tax deadlines closely.
Mistake 2 — resigning from the board without resolving the underlying problem. A director sees mounting debts, submits a resignation, and considers the matter closed. It is not. They remain liable for obligations that arose during their term. Resignation only protects against liability for debts incurred after the date of departure.
Mistake 3 — no communication with the accountant. The board does not review financial reports sent by the accounting firm. No one checks outstanding liability balances or responds to warnings about insufficient funds for tax payments. Yet ignorance of the company’s finances is not a defence in court — directors have a legal duty to know.
At Progress Holding, every client running an sp. z o.o. receives a monthly report on the status of their tax and social security obligations. When we see a company approaching the insolvency threshold, we notify the board in writing. This does not substitute for the board’s own responsibility, but it gives directors the tools to make informed decisions.
Frequently asked questions
Can a shareholder of an sp. z o.o. be personally liable for company debts?
No. A shareholder risks only their contributed capital (Article 151 § 4 KSH). Personal liability under Article 299 KSH applies exclusively to board members — not shareholders. Exception: if a shareholder also serves on the board, they are liable in their capacity as a director, not as a shareholder.
Does Article 299 KSH apply to a commercial proxy (prokurent)?
No. Article 299 KSH applies exclusively to board members. A prokurent (commercial proxy) does not bear liability on this basis — even if they effectively managed the company. A proxy may face liability under other provisions (e.g. Article 415 of the Civil Code), but not under Article 299 KSH.
What is the deadline for filing an insolvency petition?
30 days from the date on which grounds for insolvency arose (Article 21(1) of the Polish Insolvency Law, Journal of Laws 2024, item 794). Insolvency arises when the company fails to meet its due monetary obligations for more than 3 months, or when its monetary liabilities exceed its assets for more than 24 months.
Can a director file for personal bankruptcy to avoid Article 299 liability?
They can, but timing is critical. Personal bankruptcy discharges only obligations existing on the date of the declaration of bankruptcy. If a director files too early — before enforcement against the company has been shown to be unsuccessful — the Article 299 KSH claim does not yet formally exist and will not be discharged. Precise legal advice is essential.
How long do creditors have to sue a director?
3 years from the date the creditor learned of the unsuccessful enforcement against the company. The limitation is tortious in nature (Article 4421 of the Civil Code). In all cases, the claim extinguishes no later than 10 years from the event giving rise to the loss.
Does director liability apply to companies on Estonia-model CIT?
Yes. The choice of tax regime (Estonian CIT, standard CIT) has no effect on Article 299 KSH liability. The provision applies to all sp. z o.o. companies regardless of their tax treatment. Our analysis at Progress Holding confirms that companies on Estonian CIT are subject to exactly the same rules of director liability as those under the standard CIT regime.
Article 299 KSH liability is a real and serious risk for anyone serving on the board of a Polish sp. z o.o. The best protection is not resignation — it is active financial monitoring and prompt action at the first signs of insolvency. The 30-day deadline for filing an insolvency petition is absolute: every day of delay increases your personal exposure.
