How to Transfer Shares in Poland (M&A): Notarised SPA, 1% Transfer Tax, Uokik & Filing Steps (2026)

Last updated: 19 May 2026

Understanding how to transfer shares in Poland M&A transactions is essential for any buyer, seller or corporate counsel executing a private company deal in 2026. Poland’s legal framework requires that share purchase agreements for a spółka z ograniczoną odpowiedzialnością (sp. z o. o. ) be executed in writing with notarised signatures, that the buyer settle a 1% tax on civil law transactions within 14 days, and that parties assess whether UOKiK merger-control or foreign-investment screening filings are triggered before closing. Refreshed practitioner guidance issued in early 2026 has consolidated several procedural expectations around notarisation protocols and regulatory timelines, making a single, step-by-step checklist more valuable than ever.

This guide walks buyers and sellers through every stage, from letter of intent to KRS (National Court Register) post-closing filings, so that nothing falls through the cracks.

TL;DR, Six core steps to complete a share transfer in Poland:

1. Conduct due diligence and negotiate the share purchase agreement (SPA).
2. Execute the SPA in writing with notarised signatures before a Polish notary.
3. Obtain any required regulatory clearances (UOKiK, FDI screening).
4. Pay the 1% transfer tax (buyer) within 14 days and file the PCC-3 return.
5. Update the target company’s shareholders register (book of shares).
6. File amendments with the KRS and update internal corporate documents.

This article focuses primarily on the transfer of shares in a Polish sp. z o.o., by far the most common private M&A structure in Poland. Where key differences apply to joint-stock companies (spółka akcyjna, S.A.) or partnerships, these are noted explicitly.

1. How to Transfer Shares in Poland M&A, Quick Transactional Checklist

The table below distils the entire share transfer process into eight sequential steps. It answers the most common practitioner question: how do I transfer shares in a corporation under Polish law? Use it as a master reference, then read the detailed sections that follow for the procedural granularity behind each step.

Pre-signing: LOI, due diligence and the decision tree

Most Polish M&A transactions begin with a non-binding letter of intent that sets headline price terms, an exclusivity period, and the scope of due diligence. Buyers should treat due diligence as the foundation of all downstream risk allocation: the findings feed directly into reps and warranties, price-adjustment mechanisms, and indemnity clauses in the SPA. For a share transfer in Poland, due diligence typically covers corporate records, the company’s book of shares, employment and social security compliance, environmental permits, real-estate titles, and material contracts. Any restriction on transferability, such as pre-emption rights, board-consent clauses, or tag-along/drag-along rights embedded in the articles of association, must be identified at this stage, because failure to honour them may invalidate the transfer.

Signing and closing day

Polish deals may be structured as simultaneous sign-and-close or as split transactions with conditions precedent (CP) between signing and closing. In a simultaneous transaction, the SPA is executed with notarised signatures and the purchase price is transferred on the same day. In a split deal, the SPA is signed first (still with notarised signatures), and closing occurs once all CPs, regulatory clearances, third-party consents, waiver of pre-emption rights, have been satisfied. The notarisation requirement applies at the moment of signing, not closing; the share purchase agreement Poland practitioners rely on must bear notarised signatures from the outset to be valid.

Immediate post-closing filings

Once closing has occurred, three parallel workstreams start: (a) the target company’s management board must update the company’s book of shares (the shareholders register); (b) the management board files amendments with the KRS to reflect the new shareholder; and (c) the buyer must pay the 1% transfer tax and file the PCC-3 return. Each of these has its own deadline, and missing any one of them creates compliance exposure.

2. Legal Formalities: Written Form, Notarised Signatures & Representation for Share Transfer in Poland

Polish law imposes specific form requirements for a valid transfer of shares in a sp. z o.o. Understanding, and complying with, these requirements is the single most critical step in any share deal.

Why Polish law requires notarised signatures for sp. z o.o. share transfers

Under the Polish Commercial Companies Code (Kodeks spółek handlowych), a share purchase agreement transferring shares in a sp. z o.o. must be concluded in writing with notarised signatures (z podpisami notarialnie poświadczonymi). This is a mandatory form requirement; failure to comply renders the agreement null and void. The requirement extends to any ancillary agreement that forms an integral part of the SPA, for example, a preliminary agreement (umowa przedwstępna) that itself effects or commits to a transfer. Note that this is not the same as a full notarial deed (akt notarialny); the parties may prepare their own SPA document and then have their signatures notarised, which is a lighter (and less expensive) procedure than execution of a full notarial deed.

Notary procedure: what the notary certifies

When notarising signatures on a share purchase agreement in Poland, the notary public (notariusz) performs the following:

• Identity verification. The notary confirms the identity of each signatory using a valid identity document (passport, national identity card, or residence card for foreign nationals).
• Capacity check. If a signatory is acting under a power of attorney or as a corporate representative, the notary verifies the underlying authorisation document, the POA itself must be in the form required for the main agreement (i.e., with a notarised signature).
• Signature certification. The notary confirms that the signature was placed in the notary’s presence (or, in some cases, that the signatory acknowledged a previously placed signature). A notarial clause (klauzula poświadczeniowa) is affixed to the agreement, stating the date, place, identity of the signatory, and the notary’s registry reference number.
• Notarial register entry. The notarisation is entered into the notary’s official register (repertorium), creating an independent evidentiary record.

Powers of attorney, corporate representation and foreign parties

Cross-border M&A transactions frequently require at least one signatory to act through a representative. The following requirements apply:

• Power of attorney (POA). A POA authorising someone to sign the SPA on behalf of a party must itself bear a notarised signature. If the POA is executed abroad, it typically requires an apostille (for Hague Convention countries) or consular legalisation (for non-convention countries) to be recognised in Poland.
• Corporate signatories. Where a legal entity is the buyer or seller, the notary will verify that the individuals signing on its behalf have the authority to represent the company, usually through a current excerpt from the relevant corporate registry (e.g., KRS extract for a Polish entity, or the equivalent foreign registry document with a certified translation).
• Foreign-language documents. Documents in a language other than Polish presented to a Polish notary typically require a sworn translation (tłumaczenie przysięgłe) prepared by a translator certified in Poland.
• Remote execution. Polish law does not currently permit electronic signatures to satisfy the notarised-signature requirement for sp. z o.o. share transfers. Where a party cannot travel to Poland, the most common workaround is to execute the SPA before a Polish consul abroad who holds notarial powers, or to grant a POA (with notarised signature and apostille) to a Poland-based representative.

3. Transfer Tax Poland 1%: What It Is, Who Pays, Timing and Valuation

The tax on civil law transactions (podatek od czynności cywilnoprawnych, or PCC) is one of the most important compliance obligations in any Polish share deal. The transfer tax on the sale of shares is set at 1% of the market value of the shares transferred, and it is payable by the buyer.

Tax base and calculation

The PCC is levied under the Act on Tax on Civil Law Transactions. The tax base is the market value of the shares at the date of the SPA, not the contractual purchase price. Where the contractual price materially deviates from fair market value, the tax authority may challenge the declared value and reassess the tax base. In practice, transaction advisers often commission or rely on a valuation report to support the declared value, particularly in related-party deals or transactions with earn-out or deferred-payment mechanisms.

It is important to distinguish the 1% PCC transfer tax from capital-gains tax. The PCC is a transaction tax payable by the buyer at the point of share transfer. Separately, the seller may be liable to pay 19% flat-rate income tax (PIT or CIT) on any capital gain realised on the disposal. These are two distinct obligations borne by different parties.

Buyer’s payment obligation and the 14-day deadline

The buyer must file a PCC-3 tax return and pay the 1% transfer tax to the competent tax office within 14 days from the date on which the SPA is concluded. The filing and payment obligation rests exclusively on the buyer; it is not the notary’s responsibility, and it is not collected at the point of notarisation. The PCC-3 return can be filed electronically through the Polish tax administration’s e-filing system or in paper form at the local tax office.

Common exemptions and practical valuation tips

Certain transactions may be exempt from PCC. Key exemptions include:

• VAT-taxable transactions. If the sale of shares is subject to VAT (which is rare for share sales, as they are typically VAT-exempt), the PCC does not apply, PCC and VAT are mutually exclusive.
• Capital contributions. Contributions of shares to a company’s share capital (as an in-kind contribution) are treated differently and may attract PCC at 0.5% on the capital increase rather than 1% on the share value.
• Certain restructuring transactions. Mergers, demergers and transformations governed by the Commercial Companies Code have their own tax treatment and may not trigger 1% PCC in the same manner as a straightforward sale.

Practical valuation tips: in arm’s-length transactions between unrelated parties, the agreed purchase price is typically accepted as reflecting market value. In group-internal transfers or transactions with non-standard price mechanisms (earn-outs, seller loans), independent valuation support is strongly recommended to mitigate the risk of a tax-authority challenge.

4. Regulatory Filings: UOKiK Notification, Foreign Investment Screening & Sectoral Notifications

Before (or, in some cases, concurrently with) closing a share transfer in Poland, buyers must determine whether the transaction triggers any regulatory filing obligations. The three principal regimes are: UOKiK merger control, foreign direct investment (FDI) screening, and sector-specific ministry notifications.

UOKiK notification, thresholds, timing and penalty risks

Poland’s Competition and Consumer Protection Act requires mandatory pre-closing UOKiK notification for concentrations that meet the applicable turnover thresholds. The obligation applies where the combined worldwide turnover of the undertakings concerned exceeds EUR 1 billion, or where the combined turnover generated in Poland by the undertakings concerned exceeds EUR 50 million. The notification must be filed by the acquiring undertaking before closing. Implementation of the concentration before UOKiK clearance is prohibited (the “standstill obligation”).

UOKiK has two review phases. Phase I lasts up to one month from the date on which UOKiK confirms the notification is complete. If the case is complex, UOKiK may open Phase II proceedings, which extend the review period by up to four additional months. In practice, straightforward transactions are typically cleared within the Phase I timeline.

The consequences of failing to notify, or of closing before clearance, are severe. UOKiK may impose fines of up to 10% of the undertaking’s annual turnover and may order the reversal of the concentration (structural remedies). Even where the substantive outcome would be clearance, a “gun-jumping” penalty can be imposed for procedural non-compliance.

Foreign investment screening, triggers and authorities

Poland’s FDI screening regime, introduced under the Act on the Control of Certain Investments, requires prior notification and approval for acquisitions by non-EU/EEA investors (and, in certain circumstances, EU/EEA investors) in companies operating in strategic sectors. These sectors include defence, energy, telecommunications, chemical manufacturing, and other activities designated as critical infrastructure. The competent authority for FDI screening is the President of UOKiK (acting in a separate capacity from the merger-control function).

The screening obligation is triggered when the foreign investor acquires a “significant participation”, generally defined as acquiring shares representing 20% or more of total votes, or attaining a dominant position, in a protected entity. Transactions subject to FDI screening cannot close until clearance is obtained, and clearance may be subject to conditions.

Sectoral ministry filings

In addition to the UOKiK and FDI regimes, specific sectoral rules may apply. For example, transfers of shares in companies that hold agricultural real estate may trigger obligations under the Agricultural Land Act, potentially requiring notification to the National Support Centre for Agriculture (KOWR). Similarly, transactions involving companies with licences or concessions in regulated sectors (banking, insurance, energy, mining) may require the consent of the relevant sectoral regulator (KNF for financial services, URE for energy).

5. Post-Closing Registry Steps: Shareholders Register, KRS and Corporate Records

Once the share transfer is effective and the purchase price has been paid, several corporate housekeeping steps must be completed to formalise the change of ownership in the target company’s records and in public registries.

Updating the shareholders register (book of shares)

Every Polish sp. z o.o. is required to maintain a book of shares (księga udziałów) that records the name and address of each shareholder, the number and nominal value of their shares, and any encumbrances. Following a share transfer, the management board must update the book of shares to reflect the new shareholder. While there is no specific statutory deadline for this update, it should be completed promptly, industry observers expect most management boards to action this within a few business days of closing.

KRS (National Court Register) notifications

The target company’s management board is obliged to file an updated list of shareholders with the KRS. The general obligation to report changes to the registry court applies within seven days of the event. The filing must include a new shareholders list signed by all management board members, together with the relevant KRS amendment forms (submitted electronically via the S24 system or the Portal Rejestrów Sądowych). The court may also require a copy of the SPA (with notarised signatures) or the shareholders’ resolutions approving the transfer, if applicable.

Amendments to company documents

If the share transfer requires amendments to the articles of association, for example, because the articles name specific shareholders or because the transaction coincides with changes to governance provisions, a shareholders’ resolution must be adopted in notarial-deed form and filed with the KRS. Other corporate records to update include:

• The shareholders’ resolution register.
• The CRBR (Central Register of Beneficial Owners), if the share transfer changes the ultimate beneficial owner, a CRBR update must be filed within 14 days.
• Internal stakeholder notifications (banking relationships, contractual counterparties with change-of-control clauses, and insurers).

6. SPA Negotiation and Protective Clauses in Polish Share Deals

The share purchase agreement is the commercial heart of the transaction. While Polish law does not prescribe a mandatory SPA template, market practice and case law have established a set of clauses that sophisticated parties expect to see. Proper drafting at the SPA stage minimises post-closing disputes and protects both buyer and seller.

Key SPA clauses to include

Sample short clause language

The following illustrative clauses are provided for reference only and must be adapted to the specific transaction:

Notarised-signature execution clause: “This Agreement shall be executed in writing with signatures notarised by a Polish notary public (z podpisami notarialnie poświadczonymi) in accordance with Article 180 of the Commercial Companies Code. Each Party shall appear before the Notary in person or through a duly authorised representative holding a power of attorney in the form required by law.”

PCC transfer-tax clause: “The Buyer shall bear and promptly pay all tax on civil law transactions (podatek od czynności cywilnoprawnych) arising from the execution of this Agreement and shall file the PCC-3 return within the statutory 14-day period. The Seller shall provide reasonable cooperation in connection with any valuation queries raised by the competent tax authority.”

7. Timeline and Sample Checklist for Buyers and Sellers

The following indicative timeline assumes a mid-market Polish M&A transaction with a single regulatory filing (UOKiK Phase I). Timelines for larger or more complex deals, particularly those involving FDI screening or multiple sectoral consents, will be longer.

30–60 day sample timeline

Closing day flow

On closing day itself, the parties typically follow a choreographed sequence: (a) the buyer’s counsel confirms that all conditions precedent have been satisfied or waived; (b) the purchase price is transferred by wire to the seller’s designated account (or released from escrow); (c) the seller delivers any original share certificates and corporate documents; (d) the management board of the target acknowledges the transfer and begins updating the book of shares; and (e) the parties exchange signed closing confirmations. Where the SPA was signed in advance (split signing/closing), the notarised signatures are already in place and no additional notarisation is required on closing day.

Conclusion

Successfully completing a share transfer in a Polish M&A transaction demands careful coordination across legal, tax and regulatory workstreams. The core compliance architecture, notarised signatures for the SPA, the buyer’s 14-day window to pay the 1% transfer tax, and the pre-closing obligation to assess UOKiK and FDI screening requirements, has remained consistent, but the practical expectations around execution have been refined in 2026 practitioner guidance. For anyone navigating how to transfer shares in Poland M&A, the safest approach is to treat this as a sequenced checklist rather than a series of isolated steps: due diligence feeds the SPA, the SPA form feeds notarisation logistics, regulatory clearances dictate the closing timeline, and post-closing filings lock in the change of ownership.

Missing any link in the chain creates avoidable risk.
