The EU-ESO is a proposed European employee stock options scheme that would defer all income tax on developer equity until the moment you actually sell your shares — ending the practice of owing tax on gains you have not yet received in cash. It comes bundled with EU Inc., a new optional corporate form the European Commission proposed on 18 March 2026 (COM(2026) 321 final).
Legislative status: EU-ESO is a Commission proposal under the ordinary legislative procedure — not yet enacted law. The Commission’s own timetable projects adoption in 2026/27 and application no earlier than 2028. Everything described here is what the scheme would do if adopted as proposed. Any equity offer you receive today operates under existing national rules, not EU-ESO.
TL;DR:
- If adopted: no tax at grant, no tax at vesting, no tax at exercise. Tax only at disposal.
- Minimum 24-month waiting period from grant before options can be exercised (Art. 78.3(c)).
- Available only to EU Inc. companies — a new €0-capital corporate form, proposed with 48-hour digital registration at a maximum €100 fee.
- Eligible only to employees and board members of EU Inc. and its subsidiaries (Art. 78.2). Contractors and advisors are outside the scheme.
- No EU-level regulatory cap on grant value (each company sets its own maximum by shareholder vote).
- Not yet law — target agreement end of 2026; earliest application ~2028.
The Problem EU-ESO Is Solving
European startups have long struggled to attract and retain top engineering talent when competing against US offers. A large part of the gap is not salary — it is equity. US incentive stock options (ISOs) defer taxation to disposal and qualify for lower long-term capital gains rates. European schemes, by contrast, are a patchwork:
- Germany: The most relevant German regime for startup equity is §19a EStG, introduced by the Fondsstandortgesetz (2021) and extended by the Zukunftsfinanzierungsgesetz (2024): qualifying employees of eligible startups can receive actual equity participations whose taxation is deferred for up to 15 years from grant, or until employment ends or the stake is sold — whichever comes first. This defers the income tax event but does not eliminate it; the gain is still taxed as employment income when it crystallises. For the standard case where a developer holds options and exercises them, the exercise-date gain is taxable immediately under §19 EStG as ordinary income. Germany also has a §3 Nr. 39 EStG allowance of €2,000 per year for equity grants broadly available to all employees — but that scheme applies to all-employee equity grants, not to selective startup option pools.
- France: BSPCE warrants (CGI Article 163 bis G) offer disposal-only taxation and are restricted to companies under 15 years old. Following the 2026 Finance Act (effective 1 January 2026), natural persons must hold at least 15% of the share capital — meaning institutional or corporate investors can hold up to 85% while the company retains BSPCE eligibility (a liberalisation from the prior 25% natural-person floor). Most mid-stage and late-stage scale-ups still lose eligibility due to the 15-year age cap, not the ownership threshold.
- Spain, Italy, Netherlands, and most others: No harmonised tax-advantaged scheme. Options are taxed as employment income at exercise — the worst possible moment for liquidity.
The result: a developer offered options in a Berlin startup pays income tax on paper gains the moment they exercise, potentially years before an IPO or acquisition. A developer in San Francisco exercises ISOs and pays capital gains only when they sell — if at all (with careful planning).
EU-ESO is designed to eliminate this structural disadvantage in one cross-border regulation.
What EU-ESO Actually Does
Under COM(2026) 321, any company incorporated as EU Inc. could opt into the EU-ESO scheme. Options granted under EU-ESO would be subject to one core rule: taxation happens only when you dispose of the underlying shares — that is, when you sell them.
Under Article 79.2 of the proposal, income from warrants “shall be deemed not to have accrued at the time of grant of the warrant, at vesting, nor when the holder of the warrant exercises his/her right for the acquisition of shares. It shall be deemed to arise and thus be subject to taxation only at the time when the shares obtained by exercising the warrant are disposed of.”
At disposal, Article 79.3 specifies the taxable amount as the difference between the fair market value of the shares at disposal and their acquisition price. Critically, Article 79.3 then adds: “It shall be subject to taxation in accordance with national law.” This means EU-ESO harmonises when the taxable event occurs, but not at what rate. A Member State could still tax the gain as ordinary employment income at the individual’s marginal rate (potentially 45–55% in high-tax countries) rather than a preferential capital gains rate. Social security contributions are also entirely outside the proposal’s scope and remain governed by national law.
If adopted as written:
- You accept a warrant grant → no tax.
- Your warrants vest after 24+ months → no tax.
- You exercise your warrants → no tax (even if there is a large spread between acquisition price and current FMV).
- You sell your shares at exit → tax is due on the gain, at your national rate.
No more dry-tax charge on illiquid shares — but the rate applied at disposal is still a question for each Member State’s tax law.
The 24-Month Minimum: What It Means in Practice
The proposal sets a minimum holding period of 24 months before employees can exercise EU-ESO options. This is a floor, not a standard vesting schedule.
Individual companies remain free to impose longer periods — a 4-year vest with a 1-year cliff is still valid and common in VC-backed startups. The 24-month minimum simply prohibits schemes that vest faster than two years. In practice, most VC-backed companies will continue to use 4-year schedules. The significance is that EU-ESO cannot be used for very short-term retention grants that vest in under two years.
For developers evaluating offers: if a company tells you it operates under EU-ESO rules, your minimum vesting commitment before any options can be exercised is 24 months. Ask for the specific vesting schedule — 24 months is the minimum the law allows, not what you should expect to negotiate.
EU Inc.: The Vehicle EU-ESO Requires
EU-ESO is not available to companies incorporated under existing national law. It only applies to EU Inc. entities — a new “28th regime” corporate form that the Commission proposes alongside EU-ESO.
Key EU Inc. facts:
| Feature | Detail |
|---|---|
| Minimum share capital | €0 (zero) |
| Registration time | 48 hours via digital EU central interface |
| Registration cost | Maximum €100 |
| Minimum shareholders | 1 |
| Minimum directors | 1 |
| Board meetings | Online or hybrid permitted |
| Available to | Any company incorporating in an EU member state |
This is a significant departure from existing European corporate forms. A GmbH requires €25,000 minimum share capital. A Spanish SL requires €3,000. EU Inc. lowers the barrier to formally incorporating across the EU substantially.
For developers, the practical question is whether your employer is an EU Inc. or not. Most existing companies will not automatically become EU Inc. — conversion is an optional process (once transposed). If you are joining a startup being incorporated in 2027 or later, ask explicitly whether it will incorporate as EU Inc.
How EU-ESO Compares to Existing Schemes
| Scheme | Jurisdiction | Tax trigger | Annual cap | Who can receive it |
|---|---|---|---|---|
| EU-ESO (proposed) | EU Inc. (all 27 states) | Disposal only | Company sets own cap by vote (no EU-level value ceiling) | Employees + board (not contractors) |
| UK EMI | United Kingdom | Disposal (grant at market value); Exercise (if granted at discount) | £250,000/employee, £6m company-wide (2026 limit) | SMEs under 500 employees (post-2026 Budget) |
| French BSPCE | France | Disposal | None | Companies under 15 years old; natural persons hold ≥15% |
| German §19a EStG | Germany | Employment termination, sale, or 15 years from grant | None specified | Qualifying startup employees |
| US ISO | United States | Disposal (qualifying); Exercise (AMT preference item) | $100,000/year exercisable | Employees only |
| Most EU national schemes | Varies | Exercise | None or very limited | Varies |
EU-ESO’s two decisive advantages over the German scheme: no cap and disposal-only taxation. Its decisive advantage over BSPCE: no restriction to young or small startups. Its competitive position vs UK EMI: no per-employee value ceiling.
The one open question — and it is significant — is tax rate at disposal. UK EMI qualifies for 10% Entrepreneurs’ Relief (now Business Asset Disposal Relief). US ISOs qualify for 15% or 20% long-term capital gains rates. EU-ESO leaves the rate to member states, which could mean ordinary income rates in some countries. The Commission’s intent is “no less favourable treatment,” but until member states transpose and clarify, this remains unresolved.
What This Means When You Negotiate Equity Today
EU-ESO is not yet law. Any option offer you receive today operates under the national regime of your employer’s country of incorporation. Here is how to use the proposal in your current negotiations:
Ask whether your company plans to incorporate or convert to EU Inc. Some startups founded in 2026 are deliberately waiting for EU Inc. transposition. If your prospective employer plans to convert, your option terms today may include a clause about EU-ESO adoption when it becomes available.
Push for the most EU-ESO-like terms you can get under current national law. In Germany, that means asking whether the company has structured its options to maximise use of the €2,756 annual allowance. In France, ask explicitly whether BSPCE applies and what the qualification criteria are. In Spain or Italy, ask for extended post-departure exercise windows (10 years is increasingly common) to mitigate the liquidity problem.
Know that contractors are excluded. If you work as a freelancer or via a company structure, EU-ESO will not apply to you even once enacted. Employment contract, not services contract, is the prerequisite for EU-ESO eligibility under Article 78.2.
Model the disposal-only tax impact before comparing offers. Even today, a €50k equity grant in France (via BSPCE, if the company qualifies) may be worth substantially more than the same nominal grant in Germany (taxed as employment income when the event crystallises), depending on your expected hold period. Build a simple model: options × (expected exit price − exercise price) × (1 − applicable tax rate at disposal) vs the same at exercise or deferral trigger.
For US ISO offers, model the Alternative Minimum Tax. If you receive ISOs, the spread at exercise (FMV at exercise minus exercise price) is an AMT preference item — even if no regular income tax is due at exercise. For large pre-IPO option packages with substantial unrealised gains, exercising ISOs can trigger a significant AMT bill before you receive any cash. This is a known liquidity trap for startup employees that “tax at disposal” language can obscure.
