Employer of Record (EOR) platforms have made it easier than ever to hire staff across borders without a local entity. But for professionals considering Spain's Beckham Law — the special expatriate tax regime under Art. 93 of the Personal Income Tax Act (LIRPF) — the EOR structure raises a specific legal question that no EOR marketing page will fully answer: does a foreign company's use of a Spanish EOR constitute the genuine employment relationship the regime requires, or is it thin enough that AEAT (Spain's tax authority) will reject the application?
The short answer is: it depends on the substance of the EOR arrangement. The formal requirement is met. The audit risk is real. Here is what that means in practice.
The formal requirement: why EOR looks eligible on paper
Art. 93 LIRPF — the Beckham Law — requires, for the most common route (Art. 93.1.a.1), that the taxpayer is employed under a Spanish employment contract. The purpose of the rule is to ensure the regime applies to workers who have genuinely relocated to Spain for work, not to individuals who are merely registering a tax address.
An EOR with a genuine Spanish legal entity (typically an S.L. — Sociedad Limitada) employs the worker under a standard Spanish labour contract (contrato de trabajo). The EOR is the legal employer of record: it pays the salary, remits social security contributions, manages the payroll, and issues the annual withholding certificate. On paper, the employment relationship with a Spanish entity exists.
Here’s the thing: that formal compliance is necessary but not sufficient. AEAT does not look only at the employment contract. It looks at the economic substance behind the contract — specifically, who is actually acting as the employer in the functional sense.
AEAT’s substance test: the five indicators
When AEAT audits a Beckham Law application from an EOR employee, the central question is whether the Spanish entity (the EOR) is the genuine employer or merely an administrative intermediary. The substance analysis draws on AEAT’s published criteria for distinguishing genuine employment relationships from arrangements designed to exploit the regime without the underlying economic reality it presupposes.
Five indicators carry the most weight:
1. Who defines the scope and deliverables of the role?
If the job description, KPIs, project assignments and deliverables are set entirely by the foreign company — and the EOR simply passes instructions through — AEAT treats this as a signal that the foreign company is the economic employer. An EOR that receives a defined brief from the foreign client and simply on-hires the worker against that brief, with no independent role in defining what the worker does, weakens the substance argument.
2. Who supervises performance and makes promotion decisions?
Day-to-day performance reviews, line management, and promotion decisions managed exclusively by the foreign company point toward a substance problem. An EOR that has Spanish HR personnel who genuinely manage the employment relationship — including performance management and career progression within the EOR’s own framework — is in a substantially stronger position.
3. Who holds the authority to discipline or terminate?
Under Spanish labour law (Estatuto de los Trabajadores), the employer holds disciplinary and dismissal rights. If in practice the foreign company can instruct the EOR to terminate the worker and the EOR complies without independent evaluation, that chain of command undermines the EOR’s employer status. An EOR that conducts its own disciplinary process, in compliance with Spanish labour law, and that may decline a foreign client’s termination request if it would breach Spanish dismissal protections, demonstrates genuine employer authority.
4. Is Spain genuinely required for the role?
Art. 93 LIRPF was designed for workers who relocate to Spain because their work requires them to be there — not for workers who were already working remotely and simply changed their tax address. If the role is fully location-agnostic and the worker chose Spain purely for lifestyle reasons while the EOR was selected solely to create a Spanish tax base, AEAT will view the “displacement” requirement as formally but not substantively met.
This is the criterion that creates the most risk for the typical tech-sector remote worker who was already working from a laptop anywhere and wants to apply for Beckham via an EOR. The question is not whether Spain is permitted — it is whether the employment specifically required a Spain relocation.
5. Does the EOR have genuine economic substance in Spain?
An EOR that has Spanish employees, serves multiple clients, has its own management structure, and operates as an independent Spanish business is in a much stronger position than a single-purpose vehicle set up exclusively to employ one person for one foreign client. AEAT has tools to detect the latter pattern and apply heightened scrutiny accordingly.
No single indicator disqualifies an EOR arrangement. AEAT applies the substance test holistically, weighing the full picture. But an arrangement that fails on three or four of the five indicators is in meaningful legal jeopardy.
Withholding mechanics under Beckham for EOR employees
Assuming the Beckham Law application (Form 149 — Modelo 149) is approved, the withholding process works as follows:
The Spanish EOR becomes the withholding agent (retenedor). It applies the flat 24% withholding rate to the employee’s gross salary (for income up to €600,000; income above that threshold is withheld at 47%). The EOR remits these amounts to AEAT quarterly through the standard IRNR withholding return, and issues an annual withholding certificate to the employee.
The employee files an annual IRNR return (non-resident income tax, Modelo 210 — though in practice, if all income is subject to Spanish withholding with no net liability, no annual return may be required — a specialist should confirm this for each case).
One practical complexity: if the Form 149 is filed shortly after the employment start date, there will be a period when withholdings were made at the standard IRPF rate rather than the Beckham flat rate. The excess withholding can be recovered through the annual return. The EOR’s payroll system must be updated to the 24% flat rate from the official approval date, not retroactively.
Contractors and autónomos: a hard line
This is worth stating plainly, because the EOR market has muddied the waters: contractors do not qualify for the Beckham Law, regardless of how the EOR arrangement is structured.
Art. 93 LIRPF requires a genuine employment relationship — a relación laboral under the Estatuto de los Trabajadores. That means:
- An employee hired by the EOR under a standard contrato de trabajo: potentially eligible (subject to substance).
- A worker invoicing the EOR as an autónomo (sole trader): not eligible.
- A worker invoicing through their own S.L.: not eligible under the employment route (though the director route under Art. 93.1.a.3 may apply in specific circumstances).
- A worker contracted by the EOR as an independent contractor (contrato mercantil de servicios): not eligible.
Some EOR platforms offer “contractor management” alongside genuine employment. Only the genuine employment product (contrato de trabajo) can support a Beckham Law application. Before filing Form 149, verify that the contract type is unambiguously an employment contract — not a services agreement, consultancy arrangement, or autónomo registration.
Retroactive liability: the audit timeline to understand
If AEAT audits and denies the Beckham Law for years already filed under the regime, the exposure is significant. AEAT issues supplementary assessments for the difference between the 24% flat rate applied and the standard IRPF progressive liability — for every affected year.
For a high-income earner, that gap can be substantial. On €250,000 of annual income, the difference between 24% flat and the standard IRPF marginal rate (around 47% on the portion above €60,000) represents roughly €50,000–€60,000 per year. Multiplied by up to four years within the inspection statute of limitations, plus statutory late-payment interest (intereses de demora), the total exposure from a retroactive denial is very material.
Penalties apply if AEAT concludes the application was filed without a reasonable basis — though where a genuine EOR employment contract exists and the substance indicators were not clearly absent, AEAT typically frames the denial as an interpretation issue rather than a fraudulent claim.
This risk profile does not mean EOR + Beckham is off the table. It means the substance review should happen before the Form 149 is filed, not after.
The digital nomad alternative: a different structure
For remote workers who want to be in Spain and whose income comes primarily from foreign clients or employers, the Beckham Law has a second, distinct route: Art. 93.1.d LIRPF, the teleworker / digital nomad track introduced by Ley 28/2022.
Under this route, the worker retains their employment or service relationship directly with the foreign company — no EOR required. The Spanish tax authority recognises the relocation as qualifying where the worker meets the conditions of the Spanish digital nomad visa (visado de nómada digital) and at least 80% of their income derives from non-Spanish sources.
The key distinction: the EOR substance question simply does not arise, because there is no Spanish employer. The foreign employment relationship is maintained directly.
The trade-off is the 80% foreign-income threshold. A worker whose client base gradually shifts toward Spanish companies risks falling below this floor. And the digital nomad visa has its own requirements — minimum income thresholds, proof of stable foreign employment or contracts, health insurance. These are not insurmountable, but they add procedural complexity.
Whether the EOR route or the digital nomad route is more appropriate depends on the individual’s income profile, employer structure, and likely trajectory in Spain. This is precisely the kind of analysis that should be done before registering with Social Security — because the route selected at the start determines how Form 149 is completed, and the deadline for filing is six months from the start of employment.
EOR vendor due diligence: seven questions
Before signing an EOR contract with the intention of applying for the Beckham Law, ask the vendor these questions and evaluate the answers critically:
- Does the EOR have a genuine Spanish S.L. with multiple clients and operational staff — or is it a recently formed vehicle with no commercial substance beyond this engagement?
- Does the employment contract explicitly name the EOR (not the foreign company) as the employer under Spanish law?
- Does the EOR have Spanish HR personnel who will manage employment decisions independently — or is all HR service delivered remotely from outside Spain?
- Can the EOR document that it independently applies Spanish disciplinary procedures and has declined client instructions that would breach Spanish labour law?
- Is Spain specifically required for this role in a way that can be evidenced — or is it location-agnostic remote work?
- Has the EOR managed Beckham Law applications before, and can it provide examples of successful Form 149 approvals for EOR employees?
- Is the EOR willing to provide written analysis of the substance indicators for AEAT audit purposes — or does it disclaim all tax responsibility and direct you to your own adviser?
An EOR that cannot answer questions 1, 2 and 7 satisfactorily is not a suitable vehicle for a Beckham Law application, regardless of what its marketing materials say about being “Beckham-compatible.”
How BMC can help
The EOR × Beckham intersection is exactly the kind of structural question where getting advice before the event — rather than defending a denial after it — is worth the advisory cost many times over.
