More and more senior executives, tech professionals and international talent are moving to Spain with a significant part of their compensation paid outside the traditional payroll. In many cases, that compensation is linked to shares, options or long-term incentives granted by the parent company or another group entity. That is where one of the most sensitive questions in international mobility arises: how are stock options taxed in Spain, and what changes if the Beckham Law applies?
The short answer is this: it is not enough to know that an equity plan exists. You need to look at what right the individual actually received, when it was earned, when it became exercisable or payable, in which countries they worked during that period, and what their tax position is in Spain. A small mistake in any of those points can lead to a tax bill that is far higher than expected. In this guide, you will see when these incentives are actually taxed, which part may fall outside Spanish taxation, and which mistakes should be avoided so you do not pay more than necessary.
Why the Beckham Law and stock options lead to so many tax mistakes
Cross-border equity taxation rarely goes wrong because of one major misunderstanding. It usually goes wrong because of several smaller ones.
The first is assuming that every type of incentive is taxed in the same way. That is not the case: stock options, RSUs, phantom shares, free shares and ESPPs do not all receive exactly the same treatment.
The second is believing that everything depends on the date on which the executive arrives in Spain. That is not right either. In practice, a proper analysis requires a full timeline: grant, vesting, relocation, exercise, sale and, where relevant, a later move to another country.
The third is confusing two different layers of taxation. One thing is the employment-related income, which arises because the plan forms part of the employee’s remuneration. Another is the possible financial return that appears later if the shares increase in value after the employment element has already been taxed.
And the fourth mistake, probably the most expensive one, is assuming that the Beckham Law automatically covers the entire gain. In reality, where the right has been earned across different countries, the key question is what part of that income is actually linked to work carried out in Spain.
What exactly is the Beckham Law in 2026?
The so-called Beckham Law is the common name for the special tax regime set out in Article 93 of the Spanish Personal Income Tax Law. It allows certain individuals who move to Spain to be taxed under special rules, while still remaining Personal Income Tax taxpayers but under a framework that is closer to the Non-Resident Income Tax system.
Since the reform introduced by the Startups Law, the regime is now broader than it was a few years ago. It is no longer limited to the classic posted employee. Subject to the legal requirements being met, it may also apply to certain international remote workers, entrepreneurs, highly qualified professionals and some family members linked to the main taxpayer.
In very simple terms, this regime is attractive for three reasons:
- it may apply for a total of six tax years;
- it offers a more predictable tax framework for employment income;
- it requires a very careful analysis of which income is treated as sourced in Spain.
In practice, for an executive with equity compensation, the benefit does not lie in a general exemption. It lies in a special tax treatment that can be highly efficient if the plan and the timeline are analysed properly from the outset.
And that is exactly where this regime connects with stock options and other international incentives. The Beckham Law can reduce the overall tax burden in some cases, but it also forces you to determine which part of the income is truly connected to Spain and which part was earned before or outside the relocation. In plans with international vesting, that distinction is critical. It is precisely what can turn the same incentive into income that is fully taxable, partly taxable or even not taxable in Spain.
What are stock options, and how do they differ from other equity plans?
Before getting into the tax side, it is worth separating the different concepts, not so much from a purely theoretical perspective, but from a practical one: what exactly does the executive receive, and at what point can taxation arise?
Five common structures and why the distinction matters
Stock options
These give the holder the right to buy shares at a pre-agreed price. In practical terms, the key moment is usually the exercise, because that is when the economic gain arises if the market value is higher than the agreed price.
RSUs
These do not give a right to buy shares. Instead, they promise a future delivery of shares if certain conditions are met. Here, the key question is not exercise, but when the shares actually vest or are delivered.
RSAs or restricted shares
The shares may be transferred from the outset, but with restrictions relating to continued service, repurchase rights or forfeiture. In these cases, the analysis usually focuses on whether there has already been a real acquisition or whether the plan remains conditional.
Phantom shares
These do not involve real shares at all. Instead, they provide a cash amount linked to the value of the company. So rather than focusing on the purchase or sale of shares, the key issue is usually the payment date and its treatment as employment-related income.
ESPPs
These allow employees to buy company shares, usually at a discount. The practical issue here is to separate the initial discount, which may have an employment-related nature, from any later increase in value.
The difference that really matters
For tax purposes, it is not enough to know that there is an equity plan. You need to identify what type of incentive it is, what event triggers the taxable income, and whether there may later be a second layer of taxation when the shares are sold or increase in value.
That is exactly why the same compensation package can lead to very different tax outcomes under the Beckham Law. It is not just the name of the incentive that changes. The timing of taxation changes, the way the income is valued changes, and the way it is allocated can also change if the individual has been internationally mobile.
When are stock options taxed in Spain?
This is one of the most common questions, and one of the most poorly answered online. For non-transferable stock options, the critical point is usually not the grant, but the exercise, meaning the moment the beneficiary exercises the option and acquires the shares.
At that point, employment income in kind will usually arise, equal to the difference between:
- the market value of the shares on the exercise date; and
- the price the employee pays to buy them.
Put simply, if you can buy for 10 what is worth 50 on that date, the economic gain is not 50 but 40 per share. That difference is, broadly speaking, the amount that falls within the sphere of employment income.
From that point, two things may happen:
Exercise and sell
The executive exercises and sells almost immediately. In that case, the employment element still arises at exercise, but the later capital gain is usually small or even negligible if there is little or no difference between exercise and sale.
Exercise and hold
The executive exercises and keeps the shares. In that case, tax first arises on the employment element and, later, when the shares are sold, a second tax layer may appear: a capital gain or loss resulting from the change in value between the exercise date and the sale date.
This distinction is essential in order not to confuse employment income with a later investment return.
How to calculate the portion taxable in Spain under the Beckham Law
This is the real heart of the issue.
When someone moves to Spain with stock options that have already been granted, the question is not just whether the exercise takes place while they are under the Beckham regime. The real question is what portion of the right was earned while they were working in Spain.
That is why, in many cases, it is not correct to tax 100% of the gain in Spain. The right approach is to analyse the earning or vesting period and allocate the income according to the time worked in each jurisdiction.
A practical formula is the following:
Taxable employment income in Spain = total employment income × (days worked in Spain during the vesting period / total days in the vesting period)
If this is calculated properly, it can completely change the tax result.
Three basic scenarios
- Options fully earned before the move
If the entire vesting period took place before the individual arrived in Spain, the general logic is that the income should not be treated as income obtained for work carried out in Spain. - Mixed vesting
If part of the vesting period took place outside Spain and another part already in Spain, only the fraction linked to the work performed in Spain should fall within the Spanish tax treatment. - Options granted and fully earned in Spain
If grant, vesting and exercise all take place within the period of residence in Spain, the connection with Spain will be much stronger and, as a general rule, the employment income will be fully taxable here.
The key position taken by the Spanish tax authorities and why it changes the outcome
For years, many international mobility cases involving stock options were analysed too rigidly. The real practical shift came when the Spanish Directorate-General for Taxation (DGT) made it clear that the full amount arising on exercise should not always be taxed in Spain.
The idea that now drives the analysis is very clear: employment income derived from stock options should not be looked at only through the date of exercise, but also through the period of work that the incentive is intended to reward.
That has a decisive consequence: if the right was earned during a multinational vesting period, the part linked to work performed before the move should not receive the same treatment as the part earned while working in Spain.
In practical terms, this gives stronger support to a conclusion that was already reasonable in many structures, but needed technical backing: time apportionment matters, and it matters a great deal.
That does not make the analysis automatic. Quite the opposite. It requires better documentation. But it also makes it possible to defend positions that are much more closely aligned with the economic reality of the plan.
Practical examples with numbers
Let us look at three simple examples.
Example 1. Vesting completed before the move
- Grant: January 2022
- Vesting: January 2022 to December 2024
- Arrival in Spain: January 2025
- Exercise: June 2025
- Total gain on exercise: €300,000
Here, the option is exercised in 2025, but the earning period ended before the move. If the right was fully earned while working outside Spain, the logic of time apportionment leads to a clear conclusion: the income attributable to that vesting period should not be treated as having been earned for work carried out in Spain.
Key point: exercising in Spain does not, by itself, mean that the entire gain is taxable in Spain. If the right was fully earned before the move, the tax outcome may be radically different from what many people assume.
Example 2. Mixed vesting
- Grant: January 2023
- Vesting: January 2023 to December 2025
- Arrival in Spain: January 2025
- Exercise: March 2026
- Total gain on exercise: €240,000
If the total vesting period was 36 months and 12 of those months were spent in Spain, a basic approach would be:
- Spanish portion: 12/36 = 33.33%
- Taxable employment income in Spain: €240,000 × 33.33% = €79,992
The difference between taxing €79,992 and taxing the full €240,000 is substantial.
Key point: this shows very clearly why time apportionment can change the result so dramatically. This is not a minor technical nuance. It is a major economic difference.
Example 3. Exercise and hold
- Gain on exercise: €100,000
- The executive does not sell the shares
- One year later, they sell and obtain an additional €40,000 in appreciation
Here there are two layers:
- €100,000 with the nature of employment income at the time of exercise;
- €40,000 potentially treated as a capital gain on the later sale.
Where this happens in an international structure, each layer may require a different analysis.
Key point: the tax story does not end at exercise. First, employment income may arise. Later, a separate capital gain may arise, with its own rules and, in an international context, potentially tax consequences in more than one country.
What happens if vesting took place in several countries?
This is the real-life situation in a great many international moves.
There is not always just one home country and Spain. There may be a grant in the United States, part of the vesting period spent in the United Kingdom, a later move to Spain, and a final sale once the executive is resident in yet another country.
In those cases, the correct analysis requires a full timeline and five separate questions:
- What type of incentive is it?
- What is the actual period over which the right was earned?
- In which countries was the work performed during that period?
- Where was the individual tax resident on the exercise date?
- Which double tax treaty may apply?
Where vesting has taken place in several countries, it is important to avoid two very common mistakes: attributing everything to Spain just because the exercise happened there, or ignoring the fact that the original country may try to tax part of the income as well.
The problem is not only which country taxes first. The real question is how double taxation is avoided and which part of the income can reasonably be defended as unrelated to work carried out in Spain.
Mergers, plan conversions and liquidity events
The theory looks straightforward until real life intervenes.
Many equity plans change part-way through because the company:
- merges with another business;
- is acquired by a third party;
- replaces the original plan with a new one;
- accelerates vesting because of an IPO or exit;
- triggers good leaver or bad leaver clauses.
Each of these events may alter one of the elements that determine the tax treatment: the moment when the right becomes available, the valuation, the continuity of the vesting period, or even the entity that ultimately bears the cost of the compensation.
What should be reviewed in these cases?
- whether the options are cancelled, exchanged or converted;
- whether acceleration makes the right immediately exercisable or payable;
- whether the new plan preserves the traceability of the original one;
- whether the event results in payment in shares or cash;
- whether the employee’s departure changes the exercise timetable.
In this type of structure, there are rarely standard answers. The name of the plan matters less than how it actually works.
The Startups Law, RSUs and other incentives: what changes in 2026?
Since 2023, the legal environment has become more favourable for certain compensation plans used by start-ups and growth companies. That does not mean every issue has been solved, but the framework is more flexible than it used to be.
Here it is worth separating two different dimensions.
A. Access to the Beckham regime
The Startups Law broadened the types of individuals who may access the special regime: international remote workers, entrepreneurs, certain highly qualified professionals and, in some cases, related family members.
B. Specific tax treatment of equity in start-ups
The law also improved the treatment of certain share or equity awards in emerging companies. This is especially relevant for start-ups and scale-ups that use equity as a central part of compensation.
In addition, where the incentive is not a classic stock option but an RSU, restricted share or phantom share, the point at which tax arises may change:
- for RSUs, the key point is usually vesting or actual delivery;
- for phantom shares, the focus is usually the cash payment;
- for shares delivered by start-ups, special rules on exemptions and timing of taxation may apply.
That is why an article on stock options should also leave room for other plans. Many readers use these concepts interchangeably, and in practice the real issue often lies not in the label, but in the specific design of the incentive.
Formal obligations and documentation you should keep
This is where many perfectly defensible tax positions are lost in practice.
Form 149
This is the notification used to opt into the regime. The general deadline is six months from the start date of the activity shown in the Spanish Social Security registration or equivalent documentation.
Form 151
This is the annual tax return for individuals taxed under the special regime. It is filed within the standard annual filing period for each tax year.
Documents it is advisable to retain
- grant letter;
- plan rules;
- original vesting schedule and any later amendments;
- communications from HR or the compensation committee;
- evidence of exercise and, where relevant, of sale;
- company valuations, especially where the company is unlisted;
- tax certificates or withholding certificates from other countries;
- evidence of the mobility timeline and of the employing entity at each stage.
The point is not to keep paperwork just in case. The point is to be able to reconstruct a coherent tax history if the Spanish tax authorities ask questions.
Common mistakes that can be expensive
These are some of the mistakes that come up most often:
Assuming everything is taxed at exercise and that is the end of it
That is incorrect. A second tax charge may arise later when the shares are sold.
Assuming the Beckham Law covers 100% of the gain
Not necessarily. If the vesting period was partly outside Spain, part of the income may not be attributable to work carried out in Spain.
Failing to document vesting by country
Without a clear trail, defending time apportionment becomes much harder.
Overlooking the liquidity issue
Some executives exercise and trigger tax before selling a single share. If there is no sell-to-cover, net settlement or similar mechanism, the cash cost can be painful.
Relying only on Spanish payroll
In international plans, the real tax position can rarely be understood by looking only at the local payroll. You need to review the global plan, the paying entity, residence status, the treaty position and the earning period.
Filing Form 149 late or incorrectly
Losing access to the regime because of a formal mistake can be far more expensive than any technical discussion about the plan itself.
What companies should review before moving an executive to Spain
This is not only an employee issue. It is also a business issue, especially for multinationals, scale-ups and groups with internationally mobile talent.
Before relocating an executive to Spain, it is worth reviewing at least the following:
- whether the individual may qualify for the special regime;
- which equity incentives are still outstanding and on what terms;
- what portion of the vesting period has already been earned outside Spain;
- whether there will be a change of employer within the group;
- which entity will operate withholding or payments on account;
- whether there is a double taxation risk;
- whether the employee will have sufficient liquidity to bear the cost of exercise;
- which team will retain which documentation.
Experience shows that the most serious problems arise when legal, tax, payroll and global mobility teams work to different timelines or from different versions of the plan.
Good coordination does not just prevent mistakes. It can also preserve a very significant part of the net value of the compensation package.
Frequently asked questions about stock options and the Beckham Law
Are my stock options taxable in Spain if they were granted before I moved?
They may be fully taxable, partly taxable or not taxable in Spain at all, depending on when the right was actually earned and where the work was carried out during the vesting period. The grant date alone does not resolve the issue.
Does the Beckham Law apply to the entire gain?
Not always. If the vesting period was international, the usual approach is to analyse what portion of the income relates to days worked in Spain.
What if I worked in two or three countries during vesting?
It will usually be necessary to apportion the income according to the earning period in each jurisdiction and also review the relevant double tax treaty.
What happens if I leave Spain before selling the shares?
You need to separate the employment income that already arose at exercise from any later capital gain on sale. Leaving Spain does not automatically erase tax that has already arisen.
When do I pay tax: on grant, vesting, exercise or sale?
It depends on the type of incentive. For non-transferable stock options, the key point is usually exercise. For RSUs, it is usually actual delivery or vesting. And the later sale may create an additional capital gain.
Are RSUs and stock options taxed in the same way?
Not exactly. They are similar in that both usually form part of employment compensation, but the taxable event does not always arise at the same moment or through the same mechanism.
Can the same income be taxed in two countries?
Yes. That is exactly why it is essential to review the relevant treaty, the available tax certificates and the possibility of claiming relief for international double taxation.
What documentation might the Spanish tax authorities request?
In most cases, they will want to understand the timeline of the right: grant, vesting, exercise, valuation, international mobility and the basis for the calculation reported.
Does it matter whether the shares come from a foreign parent company or a Spanish subsidiary?
Yes, but not automatically. The decisive factor is not only which entity issues the shares, but also which entity employs you, where you worked during the vesting period and what real link exists between the plan and your employment activity.
What if the company has been acquired or the plan has been replaced?
You need to review whether there was an exchange, cancellation, cash-out, accelerated vesting or continuity from the old plan into the new one. This is one of the situations where the original documentation matters most.
