Why are ESOPs important for Czech startups and fast-growing companies?

Employee options allow employees to acquire a stake in the company at a preferential price set at the time the option is granted (the so-called strike price), with the real value only becoming apparent at the time of a future sale of the stake or the company's exit. 

Before the amendment effective from 2026, the Czech legal regulation of ESOPs was disadvantageous. Employees had to pay income tax and social and health insurance contributions at the moment the option was exercised, i.e., at a time when they had not yet received any cash income from the shares. This structure discouraged startups from using options, and the Czech Republic lagged significantly behind foreign markets.

The new regime of qualified employee options sets more competitive conditions. Taxation occurs only upon the sale of shares, when the employee actually receives money, and the income is also exempt from social and health insurance contributions. ARROWS helps startups and growing companies with the comprehensive setup of ESOP programs to ensure they meet legal requirements and maximize tax advantages.

What are the basic legal conditions for qualified employee options?

The new preferential tax regime is not automatically available to all companies or all employees. The law sets strict conditions that must be met by the employer (qualified employer), the employee (qualified employee), and the option itself (qualified employee option).

The conditions on the employer's side (qualified employer) require that the company has an annual turnover not exceeding CZK 2.5 billion and total assets up to CZK 2 billion. These limits are assessed at the level of the entire group if the employer is part of a consolidation unit. Furthermore, the company must not be a bank, insurance company, law firm, auditing firm, or tax advisory firm.

The conditions on the employee's side (qualified employee) stipulate that the employee must have a gross monthly salary of at least 1.2 times the minimum wage at the time the option is granted. Furthermore, the employee must have an employment relationship or be a member of a statutory body for a period of at least 12 months of uninterrupted work.

The conditions concerning the option itself (qualified employee option) are the most extensive. The option must be granted to the employee free of charge and must be non-transferable. The minimum holding period condition is also key – the employee can exercise the option and acquire shares no earlier than 3 years after the option is granted. An exception is a significant transaction, such as the sale of a controlling stake (at least a 67% share in the company) or the company's listing on a stock exchange.

In practice, however, it is not just about formally meeting the legal conditions. The entire structure of the ESOP program must be thought out to correspond to the company's business goals, fairly distribute shares among key employees, and at the same time protect the interests of founders and investors. ARROWS prepares complete legal documentation for ESOP programs, including option agreements, amendments to the articles of association or memorandum of association, and negotiation of terms with investors.

How does vesting work and why is it key for ESOPs?

Vesting is a mechanism for the gradual earning of an employee's right to a stake in the company over time or upon meeting pre-determined goals. Without properly set vesting, there is a risk that employees who leave after a few months will hold significant stakes in the company, which complicates corporate governance and makes it impossible to offer these stakes to new key people.

The basic terminology for vesting includes several terms. Grant size refers to the total size of the stake or the number of options promised to the employee. The cliff period is the minimum time an employee must work for the company before the first options begin to vest. A one-year cliff period is commonly used, meaning an employee who leaves before the year is up will not receive any options.

The vesting period is the time frame within which the employee gradually earns the promised options for smaller parts of the grant size. The most common is a four-year vesting with a one-year cliff, which means that after the first year, the employee receives 25% of the promised options at once, and the remaining 75% vests monthly or quarterly over the remaining three years.

The strike price (exercise price) is a pre-determined price at which the employee will be able to buy one share in the future after exercising the option. The strike price must be set at the Fair Market Value (FMV) at the time the option is granted; otherwise, there is a risk of an immediate tax assessment on the difference between the strike price and the FMV.

In practice, vesting structures are much more complex than they might seem at first glance. In addition to time-based vesting, it is possible to combine performance milestones, acceleration of vesting upon a change of control, reverse vesting for founders, or differentiated vesting schedules for different positions. Each of these measures has legal and tax implications that need to be carefully considered.

ARROWS has experience with dozens of ESOP structures for both Czech and international startups. Thanks to the ARROWS International network, we regularly handle cases where a Czech startup has employees in different jurisdictions or where a foreign investor requires a specific ESOP structure corresponding to their home market. Our lawyers are ready to help you.

How to correctly notify the tax authority of the choice of tax regime?

A key administrative obligation for using the preferential tax regime for qualified employee options is to notify the locally competent tax administrator of this choice. This notification must be made within the deadline for filing the employer's Uniform Monthly Report (JMHZ) for the month in which the employee acquires the option.

The General Financial Directorate has issued a non-binding model form for this notification. If the employer fails to notify the choice, or notifies it late, the qualified tax regime will not apply, and the income will be taxed in the standard way, including social and health insurance contributions.

In practice, this administration requires coordination between the company's legal, HR, and accounting departments. Startups, in particular, which often do not have a dedicated HR department, frequently overlook this obligation, leading to a situation where the ESOP program works, but employees do not receive the promised tax benefits.

In addition to notifying the choice, it is necessary to keep detailed records of all granted options, vesting, option exercises, and share sales, as this information will be needed for the tax returns of both employees and the employer. Proper record-keeping and timely fulfillment of notification duties are critical for preserving the tax advantages of the ESOP program.

ARROWS not only prepares the legal documentation for the ESOP but also coordinates with accountants and tax advisors, trains the HR department on administrative duties, and continuously monitors compliance with notification obligations towards the tax authorities. Our lawyers are ready to help you.

What are the tax consequences for employees in different scenarios?

The tax consequences for employees differ depending on whether the company uses the new regime of qualified employee options or applies the standard regime.

Under the regime of qualified employee options, effective from January 1, 2026, taxation occurs only at the moment of the sale of shares acquired by exercising the option. The income is defined as the difference between the market price of the share at the time the option is exercised and the higher of the market price of the share at the time the option was granted and the agreed option price (strike price).

Crucially, this income is considered for tax purposes to have been earned in the tax period in which the sale of the thus acquired share occurs, but no later than in the tax period in which 15 years have passed since the option was exercised. If the employee does not sell the share within 15 years, they must tax the income even without a sale.

It is also important that income from qualified employee options is taxed only with income tax under Section 10 of the Income Tax Act (other income) and is not subject to social or health insurance contributions. This represents a significant saving compared to the standard regime.

In the standard regime (for companies or options not meeting the conditions of the qualified regime), taxable income arises at the moment the option is exercised as the difference between the market price of the shares and the agreed price. This income is subject to both income tax and social and health insurance contributions, which means a total tax burden of over 40%.

Upon the subsequent sale of the shares, the employee realizes further taxable income as the difference between the sale price and the acquisition price increased by the already taxed discount. The total taxation of the employee in the standard regime can thus reach several tens of percent of the total profit from the options.

In practice, it is therefore advantageous for startups and fast-growing companies to structure their ESOP to meet the conditions of the qualified regime. If a company does not meet the conditions (for example, it has a turnover above CZK 2.5 billion), it may consider alternative incentive programs such as phantom shares or RSUs (Restricted Stock Units), which have different tax consequences. ARROWS deals with the tax and legal aspects of ESOPs daily, which can significantly shorten the time for the client and minimize the risk of errors.

What alternative incentive programs exist besides ESOPs?

Not all companies can or want to use traditional ESOPs with transfers of actual shares or stocks. For certain situations, alternative incentive programs such as phantom shares, RSUs (Restricted Stock Units), or SARs (Stock Appreciation Rights) are more suitable.

Phantom shares are virtual shares that do not represent actual ownership in the company but give the employee the right to a cash settlement corresponding to the value of the share at the time of payment. Thus, the employee does not receive actual shares but a financial reward equivalent to the growth in the company's value. The advantage of phantom shares is that they do not dilute existing shareholders and do not require changes to the ownership structure.

RSUs (Restricted Stock Units) are promises of a future transfer of shares to an employee after vesting conditions are met. Unlike options, where the employee must buy the shares at a strike price, with RSUs, the employee receives the shares directly after vesting. RSUs are suitable for situations where the company wants to provide value to the employee without requiring them to invest their own funds in purchasing shares.

SARs (Stock Appreciation Rights) give the employee the right to be paid the difference between the current value of a share and its value at the time the SAR was granted. They function similarly to options, but the employee does not have to actually buy the shares – they simply receive the cash difference.

The tax consequences of these alternative programs differ from standard options. Phantom shares and SARs are usually taxed as regular income from dependent activity at the time the cash reward is paid, including social and health insurance contributions. RSUs may be subject to deferred taxation similar to qualified employee options, but it depends on the specific structure.

In an international context, especially if a Czech startup has employees abroad or a foreign investor, structures common in the US or Western Europe, such as ISOs (Incentive Stock Options) or NSOs (Non-Qualified Stock Options), may be preferred. Thanks to the ARROWS International network, ARROWS can design and implement ESOP structures that respect both Czech law and the requirements of foreign investors and employees.

How to prepare comprehensive legal documentation for an ESOP program?

Implementing an ESOP program requires the preparation of several interconnected legal documents that must be mutually consistent and comply with both Czech law and investor requirements.

The ESOP Plan is a framework document describing the rules of the entire program. It contains the definition of eligible employees, the size of the option pool (the total number of shares or stocks reserved for the ESOP), vesting mechanisms, conditions for exercising options, and the rights and obligations of participants. The ESOP Plan is usually approved by the General Meeting.

Option Agreements concluded with individual employees specify the particular conditions for that employee. They must include the identification of the parties, the grant size (number of options allocated), the strike price, the vesting schedule, the cliff period, the conditions for exercising the option, and provisions on what happens to the options upon termination of employment.

Amendments to the articles of association or memorandum of association are necessary if the ESOP program involves an increase in share capital or the creation of a new class of shares. For joint-stock companies, it is possible to create non-voting shares specifically for the ESOP, which protects the founders' control.

A Shareholder Agreement governs the mutual relationships between all shareholders, including employees who acquire shares by exercising options. It should include the right to repurchase shares (buyback), tag-along rights (the right of minority shareholders to sell their shares along with a majority shareholder), and drag-along rights (the right of a majority shareholder to force minority shareholders to sell).

A company valuation (409A valuation or independent appraisal) is key for setting the strike price at Fair Market Value. If the strike price is set below FMV, there is a risk of an immediate tax assessment on the difference.

In practice, however, preparing these documents requires coordination with investors who may already have concluded term sheets or shareholder agreements containing provisions about a future ESOP. An ESOP is not an isolated document; it is the pinnacle of a legal pyramid that must stand on a solid foundation – clean relationships between founders and securely structured investment rounds.

What will the Startup Act bring and how will it affect ESOPs?

The Ministry of Industry and Trade is preparing a comprehensive Startup Act, which is intended to fundamentally change the business environment for innovative companies in the Czech Republic. The act aims to provide a clear legal definition of a startup, including a certification mechanism, and to offer certified firms a range of benefits.

The planned pillars of the Startup Act include defining a startup using hard conditions (company size, turnover, number of employees) and soft conditions (scalability and innovativeness). Inspiration is being drawn from successful examples in Spain, Austria, France, and Romania, where startup acts have significantly supported the growth of the innovation ecosystem.

The second pillar will be the introduction of tax and administrative relief for certified startups. Plans include, for example, a reduction in social security contributions for employees, a reduced income tax rate for startups, tax incentives for investors (business angels), and the possibility of tax deferral.

The third pillar is intended to be more flexible labor law, allowing startups to collaborate more effectively with self-employed individuals and specialists without the risk of disguised employment (the 'švarcsystém'). A flexi-contract is being introduced – a legal form of cooperation between an employment contract and self-employment, which will allow startups to scale their teams quickly.

The Startup Act is also intended to fine-tune the conditions for ESOPs to make them even more competitive. For example, this includes expanding the possibility of participation in ESOP programs to contractors and self-employed individuals, not just employees in an employment relationship.

The goal is to increase the number of startups founded by hundreds per year, raise the median valuation of Czech startups in the Series A phase by 50% within three years, and increase the number of seed investments by 100% within two years. The act is also intended to reverse the negative trend where 43% of startups with a value higher than $50 million move abroad.

Thanks to our experience in providing long-term services to more than 150 joint-stock companies and 250 s.r.o.s, we can quickly adapt ESOP structures to changing legislation.

Conclusion: Secure a competitive ESOP with professional legal support

Employee Stock Option Plans (ESOPs) represent a key tool for Czech startups and fast-growing companies to motivate and retain talent in a competitive environment. The new preferential tax regime, effective from January 1, 2026, fundamentally improves the conditions by introducing the "no tax before cash" principle and exemption from social and health insurance contributions.

However, implementing a functional ESOP program requires much more than just formally meeting legal conditions. The legal issues are more complex in practice than they might seem at first glance. Vesting mechanisms, setting the strike price at Fair Market Value, coordination with investment documentation, notification duties to tax authorities, alignment with investor rights, and preparation of buyback mechanisms – these are all steps that look simple but have hidden exceptions, procedural details, connections to other regulations, and risks that a layperson often does not see.
