ESOP in a Polish Company: A Plan That Retains Key People

You promised a key developer “a share in the company’s success.” Eighteen months have passed. Now they want to know exactly what they will receive. You have no answer, and they have an offer from a competitor with a clear equity package.

This scenario comes up in Polish startups and scale-ups more often than you might think. About 25% of Polish startups offer employees an option program, and another 30% plan to introduce one. Yet the vast majority operate without consistent rules, relying on verbal promises and slides from team presentations.

ESOP (Employee Stock Option Plan), an incentive program based on participation in a company’s capital, is one of the most effective ways to retain key people in technology companies. That is, when it is designed well. A poorly designed plan creates ownership confusion, disputes, and obstacles to future investment rounds.

This article explains how ESOP works under Polish law, which models are available, how company legal forms differ for incentive programs, the tax consequences for participants, and how to make a program retain people rather than create problems.

Key terms you need to know

Before getting into the details, let’s establish a shared vocabulary. These terms come up in every discussion about incentive programs, with both lawyers and investors.

Why an ESOP in a Polish company needs careful attention

Polish law does not have one statute governing ESOPs. The term “ESOP” does not appear in the Polish Commercial Companies Code or the Personal Income Tax Act. An incentive program must be assembled from several sources:

1. Polish Commercial Companies Code (KSH): rules on ownership structure, share issues, subscription warrants, and authorized capital
2. Personal Income Tax Act: Articles 24(11) to 24(12b), which define an “incentive program” solely for tax purposes
3. Polish Civil Code: freedom of contract (Article 353¹) as the basis for phantom shares and SARs
4. Employment law: when program participants are employees hired under employment contracts

This means every program requires coordination across corporate, tax, and contractual documentation. Leave out one element and the program either does not work or creates risk.

About 90% of Polish startups operate as limited liability companies (sp. z o.o.), a form expressly excluded from ESOP tax preferences. This creates a fundamental asymmetry that many founders learn about too late.

How to choose an incentive program model for your company

Not every incentive program requires giving away actual shares. The right model depends on three things: the company’s legal form, its stage of development, and how much control you want to retain as founder.

Actual shares or stock (equity)

The participant becomes a shareholder and gains corporate rights, including voting and dividend rights. In a joint-stock company (S.A.) or simple joint-stock company (PSA), this can be implemented through a conditional increase of share capital and the issue of subscription warrants (Articles 448 to 451 KSH, Article 453 § 2 KSH).

When this model makes sense: the company plans an exit or financing round and wants key people “on board” as co-owners.

Risk: dilution of founder control. Each share issue reduces the existing shareholders’ percentage ownership on the cap table.

Phantom shares (virtual shares)

The participant does not become a shareholder. They receive a claim, or right to a cash payment linked to the company’s value. The arrangement is based only on a civil-law contract (Article 353¹ of the Polish Civil Code). It is not regulated in the KSH.

When this model makes sense: you want to retain full ownership control, operate as a sp. z o.o., or avoid complicating the cap table before a financing round.

Risk: tax uncertainty, with two competing lines of interpretation (details in the tax section).

Subscription warrants

Securities issued by an S.A. or PSA that entitle the holder to subscribe for shares at a specified price and by a specified date, no later than 10 years. The resolution issuing them must specify: eligible persons, issue price, number of shares per warrant, and exercise deadline.

When this model makes sense: an S.A. or PSA plans a multi-stage program with shares granted at a later date.

Risk: uncertainty about tax classification. Warrants under Article 453 § 2 KSH fall under letter (a) of the Act on Trading in Financial Instruments, while Article 24(11b) of the Personal Income Tax Act refers to letter (b). A literal reading may exclude warrants from the tax preference even though they ultimately lead to shares.

Company legal form and ESOP implementation options

Your company’s legal form determines which instruments are available and whether the program can benefit from tax preferences. The differences are significant.

Limited liability company (sp. z o.o.): limitations to know in advance

A sp. z o.o. is the most common legal form for Polish startups, but it is also the most limited for ESOP:

1. No tax preference: shares in a sp. z o.o. do not meet the definition of an “incentive program” under Article 24(11b) of the Personal Income Tax Act
2. No authorized capital or subscription warrants: every capital increase requires an amendment to the company agreement and an entry in the National Court Register (KRS)
3. Work cannot be contributed as an in-kind contribution (Article 14 § 1 KSH)
4. Limits on preferred shares: at most 3 votes per share (Article 174 KSH); preferred dividends may not exceed 150% of ordinary dividends (Article 196 KSH)
5. Formal transfer requirements: a written agreement with signatures certified by a notary

If you operate as a sp. z o.o. and want to introduce an ESOP, the realistic options are phantom shares, which are contractual and have no tax preference, or converting into an S.A. or PSA before launching the program.

Simple joint-stock company (PSA): structurally the best fit for ESOP

The PSA, available since July 1, 2021, was designed with startups and incentive programs in mind:

1. Minimum share capital: PLN 1, with no entry barrier
2. Work or services may be contributed: the only type of company in which this is possible. The contribution does not increase share capital but entitles the contributor to shares.
3. Non-par-value, dematerialized shares: flexible trading and documentary form, such as email, instead of a notarial deed
4. Founder shares (Article 300²⁶ KSH): guarantee a minimum ratio between the founder’s votes and total votes, automatically increasing the number of votes with each new issue
5. Tax preference since January 1, 2022, identical to that for an S.A. (Article 24(12b) of the Personal Income Tax Act)
6. Broad freedom to set share preferences, with no fixed statutory limits

Joint-stock company (S.A.): a full set of instruments at higher cost

An S.A. offers the broadest range of corporate tools: authorized capital (Article 444 KSH), conditional capital increases (Articles 448 to 451 KSH), and subscription warrants (Article 453 § 2 KSH). Minimum share capital is PLN 100,000, which is a barrier for early-stage startups. The tax preference under Articles 24(11) to 24(12b) applies without limitations.

ESOP tax consequences: what founders and participants need to know

Tax treatment determines whether a program is attractive to participants. A poorly chosen structure may mean a key person pays tax when they receive shares, before selling them and before seeing any profit.

A program meeting Article 24(11) to 24(12b) of the Personal Income Tax Act

If your program meets all four of these conditions, the participant can defer taxation:

1. The program is a compensation system, not a one-time award
2. It is established under a shareholders’ meeting resolution of an S.A. or PSA
3. Benefits are linked to income sources under Article 12 or Article 13 of the Personal Income Tax Act, employment or personally performed activities
4. The participant actually subscribes for or acquires shares in an S.A. or PSA

Supreme Administrative Court judgment of November 28, 2025 (II FSK 262/23) confirmed that the shareholders’ meeting resolution requirement is formal and cannot be replaced by a management board resolution; the provision must be interpreted strictly.

When these conditions are met, the tax sequence is:

The company is not responsible for withholding PIT advance payments. Program income does not form the basis for ZUS social security contributions.

Phantom shares: two competing interpretations

This is where the problem starts. The Minister of Finance has not issued a general interpretation on the tax treatment of phantom shares. Two lines of interpretation exist:

Line 1 (some tax authority interpretations): income from exercising phantom shares is classified as capital income, taxed at 19% PIT, with no ZUS contributions and no withholding agent role for the company.

Line 2 (administrative court decisions, including the Regional Administrative Court in Gdańsk): phantom shares granted for incentive purposes are not financial instruments. The income is taxed under the progressive tax scale (12%/32%), the company withholds advance payments, and the benefit is subject to ZUS contributions.

The disagreement continues. If you plan a phantom share program, consider applying for an individual tax ruling from the National Revenue Information Service (KIS). Following it provides protection: no late-payment interest and exclusion of fiscal criminal liability under Articles 14k to 14m of the Tax Ordinance.

How to design an ESOP that really retains people

An incentive program on a slide and one that works are two different things. The difference is in the mechanics: vesting, exit clauses, and consistency with company documentation.

Set the business goal before choosing the legal model

Before engaging a lawyer, answer five questions:

1. Who do you want to retain? Founders, C-level executives, key employees, B2B contractors: each group may have different program terms under one framework
2. For how many years? Standard vesting is 3 to 4 years, but if you plan an exit in 2 years, the schedule needs to reflect that
3. What should motivate participants? Loyalty through time-based vesting, results through KPI-based vesting, or both through a hybrid model
4. How much ownership control do you want to retain? Actual shares dilute control; phantom shares do not
5. What is your legal form, and do you plan to change it? A sp. z o.o. without tax preference versus a PSA with full flexibility

Design vesting mechanics and exit clauses

Market standards in Polish startups:

Note: Polish law has no standardized definitions of good leaver or bad leaver. These clauses are created by contract alone. Their precision in program documents determines whether they can be enforced in a dispute.

Check consistency with the company’s existing documents

The ESOP must not conflict with:

1. The company agreement: check transfer restrictions on shares or stock, consent requirements, and rights of first refusal
2. The shareholders’ agreement (SHA): drag-along, tag-along, anti-dilution, and lock-up clauses may limit or block new share issues for an ESOP
3. The cap table: the ESOP pool should be a separate category and updated with each capital transaction
4. Management board rules: if the board has authority over authorized capital (Article 444 KSH), check the scope of that authority

Put informal equity promises in order

If you have ever told someone “we’ll figure something out” or “you’ll share in the company’s success,” gather those promises in one place: emails, presentations, and meeting notes. Assess which of them may create legal claims.

An informal equity promise is a ticking time bomb, especially when a key person leaves or an investor examines your cap table during due diligence.

Plan how you will communicate the program to the team

Even a well-designed program loses value if participants do not understand the rules. Prepare one plain-language summary, not a legal memo, explaining:

1. Who is covered by the program and on what terms
2. How vesting and the cliff work, with specific dates or a schedule
3. What happens when someone leaves, good leaver versus bad leaver
4. What happens during a financing round or exit
5. When and how participants exercise their rights

Appoint one program owner within the company, such as the CEO, CHRO, or Head of Legal, to implement and manage the program and enforce its rules. Without a clear owner, the program stalls.

ESOP implementation costs: what to expect

Public-law charges connected with implementing an incentive program depend on the company’s legal form and the chosen model:

Legal and tax advisory costs vary with the program’s complexity, the number of participant groups, and the company’s legal form. The perspective is straightforward: the cost of designing and implementing a consistent program is many times lower than the cost of losing a key person, blocking a financing round, or entering a years-long legal dispute with a departing participant.

We can help

Designing an ESOP is a process that combines corporate law, tax, contracts, and internal communications. Downloading a template from the internet is not enough. The program must fit your company’s legal form, stage of development, investment plans, and team structure.

At Sawaryn & Partnerzy, we combine corporate law with business context, from reviewing the cap table and choosing a program model to designing vesting mechanics and good leaver/bad leaver clauses, preparing corporate documents, and communicating with participants.

We work with founders, boards, and CFOs at technology companies who need an incentive program that:

1. Is consistent with the company agreement, SHA, and cap table
2. Uses available tax preferences
3. Does not block a future financing round
4. Has clear rules for departures, role changes, or transactions
5. Is understandable to participants, not just lawyers

ESOP is a growth tool, not a legal formality

An incentive program can be one of the strongest retention arguments at your company. It can also create more confusion than value if the company grows faster than its ownership and corporate governance.

If you promise key people a share in the company’s success, formalize those promises before they become a source of disputes. If you are planning a financing round, organize the cap table and equity commitments before an investor does it for you during due diligence.

Frequently asked questions

Can I introduce an ESOP in a sp. z o.o., or do I have to convert to an S.A. or PSA?
You can introduce an incentive program in a sp. z o.o., but with limitations. Shares in a sp. z o.o. do not qualify for the tax preference under Articles 24(11) to 24(12b) of the Personal Income Tax Act. You cannot use authorized capital or subscription warrants. The realistic options are phantom shares, a contractual arrangement without the tax preference, or converting to a PSA or S.A. before launching the program. If you plan a financing round, VC investors generally expect an S.A. or PSA form anyway.

What percentage of the cap table should I allocate to an ESOP?
At the seed stage, the market standard in Poland is a pool of around 5% to 10% of capital on a fully diluted basis. Industry articles indicate a range of 10% to 15% for VC-funded companies. The pool size depends on the company’s stage, hiring plans, and investor expectations. The ESOP pool should be a separate category on the cap table and updated with every capital transaction.

How are participants taxed under an ESOP: when do they pay, and how much?
If the program meets Articles 24(11) to 24(12b) of the Personal Income Tax Act, shares in an S.A. or PSA, a shareholders’ meeting resolution, and a compensation system, tax is deferred until the shares are sold for consideration. The rate is 19% PIT on the gain, reported on PIT-38, with no ZUS contributions. Phantom shares are uncertain: the Minister of Finance has issued no general interpretation, and two competing interpretations exist, 19% versus the 12%/32% progressive scale plus ZUS contributions. Consider applying for an individual KIS ruling.

What should I do about informal equity promises I have already made to key people?
Gather all promises in one place: emails, presentations, and meeting notes. Assess which may create legal claims. Then decide whether to formalize them in a consistent ESOP, with clear vesting, a cliff, and exit clauses, or negotiate new terms with participants. Do not ignore the issue. Unresolved promises can block a financing round or lead to a dispute when a key person leaves.

How does a PSA differ from an S.A. for ESOP purposes?
A PSA has a lower entry threshold (PLN 1 in capital versus PLN 100,000), allows work or services as a contribution, has non-par-value and dematerialized shares, and permits transfers in documentary form, such as email. Since January 1, 2022, a PSA has the same tax preferences as an S.A. Another advantage is founder shares (Article 300²⁶ KSH), which automatically protect the founder’s votes with each new share issue. An S.A. offers a broader set of corporate instruments, including warrants and authorized capital, but at higher cost and with more formalities.

How does an ESOP affect a future financing round?
VC investors expect an organized cap table with a separate ESOP pool. Unresolved equity commitments can delay or block a transaction. Check that the program does not conflict with SHA clauses such as drag-along, tag-along, and anti-dilution. Decide whether the ESOP pool is calculated pre-money or post-money, as this affects who “pays” for dilution. Plan vesting acceleration on exit, single-trigger versus double-trigger, before an investor imposes their own terms.
