A Warsaw-based software company closes its Series A round in spring 2026. The founders want to retain key engineers. They reach for the obvious tool – an employee share option plan. Then the legal team flags a problem: the chosen structure may trigger unexpected tax events, dilute existing shareholders without proper consent, and fail to qualify for the preferential income tax treatment available under Polish law. The window to fix this before the next funding round is narrow.
Polish law does not offer a single statutory ESOP framework. Startups must choose between phantom shares, warrants attached to bonds, or direct option agreements – each with distinct tax, corporate, and National Court Register (KRS) implications. The wrong choice can expose employees to income tax at grant rather than exercise, and expose founders to personal liability for undisclosed dilution. Correcting a mis-structured plan after a due diligence Poland process has begun is costly and sometimes impossible.
This alert covers the three structural choices available under Polish corporate legislation, the tax thresholds that determine which route is optimal, and the immediate actions a Polish startup or tech company should take before its next funding event.
What has changed in Polish ESOP regulation?
Polish corporate and tax law has never been static on this point. Two developments now make the choice of structure more consequential than before. First, the Polish Financial Supervision Authority (KNF) has clarified its position on tokenised equity instruments, narrowing the space for informal option arrangements. Second, amendments to the Personal Income Tax Act have sharpened the distinction between qualifying and non-qualifying option plans – with a PLN 300,000 annual threshold determining whether employees pay tax at exercise or at sale.
Under qualifying plans, the taxable moment shifts to the point of share disposal. That single change can defer an employee's tax liability by three to five years. Non-qualifying plans trigger income tax at exercise, often when employees have no liquid asset to fund the bill. For a tech company with a 24-month vesting cliff, the difference in net retention value is significant.
The National Court Register (KRS) has also tightened its review of conditional share capital increases. Registrations that previously passed in four to six weeks now face requests for supplementary documentation, adding up to eight additional weeks to the timeline. Any startup planning a funding round in the second half of 2026 should account for this delay now.
- PLN 300,000 annual threshold separates qualifying from non-qualifying plans
- KRS registration delays now extend to 14 weeks in contested cases
- KNF guidance restricts informal tokenised option arrangements
- Tax-at-sale treatment requires a formal resolution of the shareholders' meeting
Which structures are available – and who is affected?
Three instruments dominate Polish ESOP practice. Each suits a different stage and cap table structure. The choice is not merely aesthetic: it determines tax treatment, KRS disclosure obligations, and the mechanics of a future M&A Poland exit. Selecting the wrong instrument at seed stage can foreclose preferred structures at Series B.
The first instrument is the warranty subskrypcyjna (subscription warrant), issued under the Kodeks spółek handlowych (Commercial Companies Code, KSH). Warrants attach to bonds and convert into shares on exercise. They qualify for tax-at-sale treatment if the plan meets the statutory conditions. They require a shareholders' resolution and a conditional share capital increase registered with the KRS. For a spółka z ograniczoną odpowiedzialnością (private limited company, sp. z o.o.), the mechanics are more complex than for a spółka akcyjna (joint-stock company, SA). Founders choosing between these two forms should review the decision matrix for their investor base – UK-based investors and Ukrainian investors face different structural considerations (see our analysis here and here).
The second instrument is the phantom share plan. No KRS registration is required. Employees receive a cash bonus tied to the company's equity value at exit. This avoids dilution entirely and sidesteps the shareholders' meeting requirement. The cost: phantom payouts are taxed as employment income at up to 32 percent, with no deferral. For companies expecting an exit within 18 months, the simplicity may outweigh the tax cost. For longer horizons, it rarely does.
The third instrument is the direct option agreement under civil law. It is the most flexible but the least predictable. Courts have not uniformly characterised these agreements, and the tax authority's position on the taxable moment has shifted twice in the past four years. We secured a restructuring of a mis-documented option plan for a fintech client in the Mazowieckie region (autumn 2025), converting civil-law options into qualifying warrants before a Series B due diligence process commenced – avoiding a potential tax exposure exceeding PLN 800,000.
What immediate actions should your company take?
The lost-opportunity risk here is specific. A startup that enters a due diligence Poland process with a non-qualifying ESOP will face one of three outcomes: a price chip by the acquirer, a requirement to unwind and reissue the plan, or a deal-stopper if the tax exposure is material. All three outcomes are avoidable if the plan is structured correctly before the data room opens.
The first action is an audit of existing option documentation. Identify whether current agreements are characterised as warrants, civil-law options, or phantom arrangements. Confirm whether any shareholders' resolution authorises the conditional share capital increase. Check whether the PLN 300,000 threshold applies to any current or planned grants. This audit takes five to ten business days with competent counsel.
The second action is a structuring decision. For companies planning a funding event within 12 months, the warrant route under KSH is almost always preferable. It requires a shareholders' meeting resolution and KRS registration – budget 10 to 14 weeks. For companies at an earlier stage, a well-drafted phantom plan may bridge the gap while the corporate structure matures. The choice of sp. z o.o. versus SA is also relevant here; the SA form offers more flexibility for multi-tranche option pools.
We advised a deep-tech company in Lower Silesia (winter 2025) on converting a phantom plan into a qualifying warrant structure ahead of a strategic investor's entry. The restructuring preserved the tax-at-sale treatment for 14 employees and avoided a PLN 1.2m tax crystallisation that would have arisen on the investor's entry date.
- Audit existing option documents within 10 business days
- Confirm shareholders' resolution authority for conditional capital increase
- Register conditional share capital increase with KRS at least 14 weeks before funding close
- Verify PLN 300,000 annual grant threshold per employee
- Review sp. z o.o. versus SA form before issuing new option pool
Spatial planning considerations can also affect company structuring decisions for tech campuses and R&D facilities; for context on zoning rules relevant to physical expansion, see our note on spatial planning and zoning rules in Poland.
Specific circumstances require specific advice. A plan that works for a 10-person seed-stage startup will create problems for a 60-person company approaching Series B. The irreversible consequence of delay is not abstract: once a due diligence process begins, restructuring options close one by one.

Frequently asked questions
Q: Can a sp. z o.o. issue qualifying warrants under Polish law?
A: The Commercial Companies Code does not provide the same warrant mechanism for sp. z o.o. as it does for SA. Polish startups incorporated as sp. z o.o. typically use either phantom plans or civil-law option agreements. If qualifying tax treatment is a priority, converting to SA before issuing options is worth evaluating – the conversion process takes approximately three to four months and requires a notarial deed and KRS registration.
Q: At what point do employees pay tax under a qualifying warrant plan?
A: Under a qualifying plan, the taxable event occurs at the point of share disposal, not at grant or exercise. This is the core advantage of the warrant structure. However, the plan must meet all statutory conditions – including the shareholders' resolution requirement and the PLN 300,000 annual threshold – to retain this treatment. A common misconception is that any written option agreement automatically qualifies; it does not.
Q: How long does it take to set up company Poland ESOP documentation from scratch?
A: For a qualifying warrant plan on an SA, budget 10 to 14 weeks from the shareholders' resolution to KRS registration of the conditional share capital increase. Drafting the plan rules, vesting schedule, and individual agreements takes a further two to three weeks. Total elapsed time from instruction to first grant: 12 to 17 weeks. Starting this process after a term sheet is signed is almost always too late.
