Phantom Shares and Stock Options in Spain
Design the right incentive plan for your Spanish startup: phantom shares, stock options, vesting and equity-linked rewards coordinated with tax, your SHA and cap table.
Let's design your incentive planWhat an incentive plan is for, and why it is often done wrong
When a startup cannot compete with a large company's salary, offering a share of the value it may create is one of the tools available: phantom shares, stock options or other equity-linked incentives for employees, directors, advisors or key collaborators. This applies as much to a Spanish startup with an international team, a foreign-founded company or a SaaS business hiring across borders as it does to a purely domestic one.
These instruments are not interchangeable, and getting the choice wrong — or drafting it without care — creates problems that surface exactly when they are hardest to fix: in an investment round's legal due diligence, in a later acquisition, or when a key person leaves the company.
This page will not tell you which instrument to use without knowing your case. What it does is explain how each one works, what to watch for, and how we design the plan with you.
Phantom shares: incentive without touching your cap table
What they are, and what they are not
A phantom share is a contractual economic right: the beneficiary is entitled to a payment calculated by reference to the company's value or to a defined event — a sale, a funding round — but does not receive actual shares. It carries no shareholder status, no voting rights, no entry in the shareholders' register, and it does not by itself dilute the cap table. Phantom shares do not make the beneficiary a shareholder; that is one of the most frequent misunderstandings we correct before a plan goes out.
When they fit
They tend to fit when you want to give someone exposure to the company's success without changing your corporate structure: directors or collaborators you do not want — or cannot, under your shareholders agreement — bring into the capital. They also help keep the cap table simple ahead of an investment round.
Stock options: real equity for the team
How they work in a Spanish company
A stock option gives the beneficiary the right to acquire shares at a price agreed in advance (the strike price), typically after a vesting period. If the company gains value, that right can become valuable; if exercised, the beneficiary becomes an actual shareholder, with the effects that has on your cap table. Anglo-style plans — however they are labelled abroad — are built around foreign corporate and tax concepts that do not automatically transfer to a Spanish SL: they can be used as a reference, but need adapting to Spanish company law and to your own bylaws, not copied as-is.
The Startups Law tax regime, in broad terms
Spain's Startups Law introduced a specific tax treatment for certain stock option plans, tied to requirements around the type of company, the beneficiary, and the timing of the grant and exercise, among others. We describe it here only in broad terms, because it is not a benefit every startup or every plan qualifies for automatically — whether it applies to your case needs reviewing before you rely on it, alongside our startup tax advisory.
Phantom shares or stock options: which fits your case?
There is no universal answer: it depends on your cap table, on who you want to incentivise, and on the stage your company is at. As general orientation — not a fixed rule:
| Criterion | Phantom shares | Stock options |
|---|---|---|
| Dilution | Does not dilute the capital | Can dilute if exercised |
| Cap table | Unaffected | Changes on exercise |
| Beneficiary status | Not a shareholder | Can become a shareholder |
| Tax | Depends on the case and the timing of payout | Depends on the case and the timing of exercise |
| Complexity to set up | Contractual, usually more agile | Needs corporate fit with your bylaws and SHA |
Not sure which instrument fits your case? We look at it in a call: your cap table, who you want to incentivise, and how it should connect with your next financing round.
Vesting, cliff and leavers
Both phantom shares and stock options are usually granted with a vesting period: the right builds up over time or against milestones, instead of being granted in full on day one. A cliff — a minimum period before anything starts vesting — is common, though there is no single fixed schedule that fits every plan; it is agreed case by case.
What actually determines whether the plan works is not the percentage offered, but what happens in the uncomfortable scenarios: what happens if the beneficiary leaves before vesting completes, what happens on an exit, and how that interacts with your shareholders agreement. If these leaver clauses are not clear from the start, the plan creates more conflict than motivation.
Founder vesting and reverse vesting
This is a different question from the employee incentive plans above: founder vesting (often called reverse vesting) applies to the shares co-founders already hold, not to a new instrument granted to the team. It sets out what happens to a founder's own equity if they leave early — commonly, that unvested shares return to the company or to the remaining founders, rather than staying with someone no longer involved.
Investors usually expect this to be in place before an investment round, and it needs to be documented consistently with your shareholders agreement and bylaws — not as a plain bonus arrangement or an informal understanding between founders.
Tax: what to know before you design it
The tax treatment of a phantom share or stock option plan is not a single box to tick: it depends on the specific instrument, on who the beneficiary is, on the timing of exercise or payout, and on whether certain requirements are met in each case. It is not the same to design a plan for an employee as for a director or an external advisor, nor is it the same to be paid on exercise as on a later sale. Our startup tax advisory covers this alongside the company's own tax.
If a beneficiary is also relocating to Spain and may qualify for the Beckham Law's special regime, that is a separate personal-tax matter for that individual, reviewed on its own facts — not something we fold into the incentive plan's design.
International teams: extra questions when your people are abroad
Startups with team members based outside Spain, or foreign founders building a Spanish SL from abroad, add a layer that a purely domestic plan does not have: where the beneficiary is tax resident, whether their local law recognises the instrument the same way Spanish law does, and how payout or exercise is handled across borders. These questions need reviewing case by case — there is no single answer that covers every jurisdiction a beneficiary might be in.
If you are also setting up or structuring the Spanish side of your operation, our startup lawyer in Spain hub and our company formation guide for foreign founders cover the broader legal setup this plan needs to sit within.
How we design your incentive plan
Diagnosis and objectives
We look at who you want to incentivise, your current cap table, your shareholders agreement and your funding plans, and tell you whether an incentive plan makes sense and which instrument tends to fit.
Plan design and instrument choice
We define the rules that make the plan work in practice: vesting, cliff, leaver scenarios, strike price if relevant, and how it fits your corporate structure.
Documentation and rollout
We draft the plan framework and individual grant letters, coordinate the fit with your bylaws and shareholders agreement, and leave it ready to roll out to your team. For ongoing questions afterwards, our startup advisory service picks up where this leaves off.
Frequently asked questions
What is the real difference between phantom shares and stock options?
Phantom shares are a contractual economic right: the beneficiary is paid an amount linked to the company's value or to a defined event, but never becomes a shareholder. Stock options give the right to acquire actual shares in the future at an agreed price; if exercised, the beneficiary does become a shareholder. The first does not touch your cap table; the second can, if exercised.
Do phantom shares make the beneficiary a shareholder?
No. This is one of the most common misunderstandings. Phantom shares carry no shareholding, no voting rights and no entry in the shareholders' register. They are a contractual right that can replicate, to the extent agreed, the economic effect of holding shares, without the beneficiary actually holding any.
Do stock options work in Spain exactly like in the US or UK?
No. Anglo-style plans are built around foreign corporate and tax concepts that do not automatically transfer to a Spanish SL. They can be used as a reference, but the plan, the strike mechanics and the fit with your bylaws and shareholders agreement need adapting to Spanish company law.
How are phantom shares or stock options taxed?
It depends on the instrument, the beneficiary, the timing of exercise or payout, and whether certain requirements are met. There is no single rule and no automatic exemption from tax, so this needs reviewing before the plan is designed, not after it is already in place.
Does every startup qualify for the Startups Law tax treatment on stock options?
No. Any particular tax treatment linked to Spain's Startups Law or to emerging-company status depends on requirements around the company, the beneficiary, timing and documentation, assessed case by case. We do not treat it as a guaranteed benefit for any tech company.
What happens to unvested phantom shares or options if someone leaves?
That depends entirely on what the plan says about leavers, and this is exactly the kind of clause that needs deciding upfront, not improvised when someone actually resigns. We do not offer a fixed vesting schedule as a default — it is designed around your situation.
How much does it cost to design or review our incentive plan?
It depends on the instrument chosen, the number of beneficiaries, and whether we are starting from scratch or reviewing an existing plan. We give a fixed quote once we understand what you need.
