Employer Letter for Spain's Digital Nomad Visa: Time Limits and Permanent Establishment Risk (2026)

The employer letter for Spain's Digital Nomad Visa is the document in which your foreign company authorises you to work remotely from Spain. Under Article 74 ter of Law 14/2013, employees must prove that the company allows remote work, and the UGE asks for this letter as that proof.

Two problems come up before filing. Some employers limit the authorisation to a few months. Others hesitate to sign because they fear that one employee in Spain creates a permanent establishment and a Spanish corporate tax bill.

The short answer to both: a time limit in the letter can shorten your residence permit to the same period, and a remote employee does not create a permanent establishment automatically. Spanish law looks at specific facts, and most of them can be checked before you ask for the letter.

Key Takeaways

• Employees need a letter from the foreign company authorising remote work from Spain, stating their role, functions and salary in euros.
• No official rule sets an expiry date for the letter, but it must match your contract and the payslips from the three months before you apply.
• The residence authorisation is granted for the period requested, up to three years. A letter limited to four months can mean a four-month permit.
• Never edit a signed letter yourself. Ask your employer for a new one.
• A permanent establishment requires a fixed place of business at the company's disposal, or an agent who habitually signs contracts for it. A home office chosen by the employee is lower risk, never zero risk.
• Social security and payroll duties are separate from permanent establishment.

What the Employer Letter for Spain's Digital Nomad Visa Must Contain

Article 74 ter of Law 14/2013 requires employees to prove two things about their job: that the employment relationship has existed for at least the last three months, and that the company allows the work to be done remotely.

The UGE (Unidad de Grandes Empresas y Colectivos Estratégicos), the unit that decides applications filed from inside Spain, turns that into a specific document. Its published documentation list asks for a letter from the foreign company that authorises the work from Spain and states your job profile, your main functions, an express statement that the job can be done by remote means, your salary in euros and the remaining conditions of the remote arrangement.

Wording matters. The UGE reads the letter and the contract closely for any reference to office attendance, client visits or other location-dependent duties. Our guide for remote employees covers what the letter must and must not say, and the document checklist shows where it sits in the full file.

How Recent the Employer Letter Needs to Be

Neither Law 14/2013 nor the UGE's documentation list sets an expiry date for the employer letter.

That does not make an old letter safe. The letter has to describe your situation on the day you file, and the UGE checks it against your contract, your payslips from the three months before the application and the bank statements showing those payments. A letter signed before a pay rise, a change of title or a new contract will contradict the rest of the file.

The practical rule is to ask for the letter last, so that it is dated close to filing. If your application is delayed and something changes, ask for an updated letter.

The letter is a private document, so it needs a sworn translation if it is not written in Spanish, but no apostille. Our article on apostilles and employment proof explains the distinction.

What Happens When Your Employer Limits the Letter to a Few Months

Some legal teams agree to the move but limit the authorisation, for example to four months, because they believe a short stay keeps the company clear of Spanish tax.

The limit has a direct immigration effect. Under Article 74 quater.1, the visa issued by a consulate lasts up to one year, unless the work period is shorter, in which case it lasts as long as that period. Under Article 74 quinquies.2, the residence authorisation requested from inside Spain lasts up to three years, unless it is requested for a shorter work period.

The Dirección General de Gestión Migratoria confirmed this reading in its Management Criterion 2/2025 of 16 July 2025. Authorisations for international teleworkers are granted for the period requested, up to three years, and the law sets no minimum duration.

In practice, a letter that authorises four months of remote work supports a four-month authorisation, and you would need a new letter and a renewal within months of arriving.

Take Daniel, an invented example: a data engineer whose employer signs a letter allowing him to work from Spain for a maximum of four months. He wants the three-year permit, and he has two legitimate options: file with the letter as it is and accept a short authorisation, or go back to his employer with the information its legal team needs to remove the limit.

There is no third option. Deleting the clause or changing the dates yourself means filing a falsified document. It can lead to a refusal, weaken any later application and create serious problems with your employer and under Spanish law.

What a Permanent Establishment Is Under Spanish Tax Law

A permanent establishment (establecimiento permanente) is the level of presence at which a foreign company becomes taxable in Spain on the profits linked to that presence. It is a risk for the employer, not for the employee, and one of the terms in our glossary of Spanish terms.

Article 13.1.a of the Non-Resident Income Tax Law (Royal Legislative Decree 5/2004) gives two routes.

The first is a fixed place of business: the company has, on a continuous or habitual basis, premises or workplaces of any kind in Spain where it carries out all or part of its activity.

The second is a dependent agent: someone in Spain who is authorised to conclude contracts in the company's name and habitually uses that authority.

Where a double taxation treaty applies, its own definition takes priority. Spain's treaties generally follow Article 5 of the OECD Model Tax Convention.

When a Remote Employee in Spain Creates Permanent Establishment Risk

A home office is not automatically the company's place of business. Two official sources show how the question is analysed.

The first is binding consultation V0066-22 of the Dirección General de Tributos, dated 18 January 2022. It concerned a UK company whose employee worked from his own home in Spain. The DGT found no permanent establishment: the home was not at the company's disposal, the company paid nothing for its use, and the employee did not habitually conclude contracts. It also stressed that each case depends on its own facts.

That consultation is useful for its criteria, not as a guarantee. The employee had stayed in Spain on his own initiative and without the company's agreement, whereas a Digital Nomad Visa employer signs an authorisation.

The second is the 2025 update to the OECD Model Tax Convention, approved on 18 November 2025. Its Commentary on Article 5 treats a home used for less than 50% of working time over twelve months as generally not a place of business. Above that level, the question is whether the company has a commercial reason for the work to be done from that country.

A Digital Nomad Visa holder works from Spain almost all the time, so the commercial reason test is the one that matters. The Commentary guides how treaties are interpreted and is not Spanish legislation.

The clearest risk case is a director who runs the company from Spain: a place of management is one of the examples of permanent establishment listed in Article 13.1.a. An employee with no management role and no authority to sign contracts sits at the lower end.

None of these factors settles the question alone. A company that wants certainty should ask its own tax adviser for a written opinion on its facts.

Social Security and Payroll Obligations Employers Confuse With Permanent Establishment

Three different obligations get merged in these conversations: corporate tax, social security and payroll withholding.

Social security is the one your visa file has to settle. If an A1 or a certificate of coverage under a social security agreement is available, you stay in your home system. If not, the usual route for an employee is for the foreign company to register with the Tesorería General de la Seguridad Social and pay Spanish contributions.

Registering with Spanish Social Security does not, by itself, create a permanent establishment for corporate tax purposes. Our guide to applying without a social security agreement explains both routes.

Payroll withholding of Spanish income tax is a third question. It depends on whether the company is considered to operate in Spain, and it is one for the company's tax adviser.

How to Raise the Employer Letter With HR, Legal and Finance

Start by finding out which risk worries them. "Tax exposure" can mean permanent establishment, social security or payroll, and each has a different answer.

Then give them facts, because facts are what the legal tests use. Useful points to set out are that the move is your request, that your duties stay the same and serve the business outside Spain, that you have no authority to sign contracts for the company, that the company will not pay for or control your home, and that it has no entity, office or staff in Spain.

Only state what is true. A letter describes facts, and the tax conclusion belongs to the company's adviser, so neither you nor an immigration letter can guarantee that no permanent establishment exists.

How the letter describes the reason for the move also has to be consistent with your social security certificate, so the wording should be agreed with your lawyer before anyone signs.

Our article on Employer of Record arrangements explains why moving you to an EOR does not solve the problem.

Hoply's lawyers review the employer letter, the contract and the social security certificate together before filing, so you can send your case for a free evaluation and go to HR knowing what the letter needs to say.

What to Do if Your Employer Refuses to Sign

Without the letter, the employee route is closed in practice. The UGE's documentation list asks for it specifically, and filing without it invites a requerimiento (the UGE's formal request for more documents) or a refusal.

A first refusal is not always final. If the objection is tax risk, a written opinion from the company's adviser may be enough to change the answer. If it is the open-ended commitment, a letter for a defined period still works, and your permit will follow that period.

If the refusal is final, the alternatives change your legal position and need review first. Becoming a genuine independent contractor is a different relationship with different tax and social security consequences, not a relabelled employment contract. Company owners follow a separate route, explained in employee or business owner.

Getting Your Employer Letter Reviewed Before You Apply

The employer letter decides more than it seems to: whether the UGE accepts the remote arrangement, how long your permit lasts and whether your file is consistent from contract to payslip.
