Can My UK Employer Keep Me as an Employee While I Live in Spain?

Many British employees assume that moving to Spain is straightforward: keep the same UK job, stay on UK payroll, move to Spain and continue working remotely.

In reality, three separate systems are involved: immigration, Social Security and taxes. Many Digital Nomad Visa applicants focus on the visa itself and only later discover that Social Security and tax residency can be more complicated than the visa itself.

For UK employees, one document often becomes the key to the entire arrangement: the A1 Certificate.

How Did Brexit Change Things?

Before Brexit, UK citizens benefited from EU freedom of movement and did not need special immigration permission to live and work in Spain.

After Brexit, many people assumed that working remotely from Spain for a UK employer would become impossible or would automatically require becoming autónomo.

That is not the case.

The UK and EU continue to coordinate Social Security in many situations, which is why A1 Certificates remain relevant for British employees moving to Spain.

However, Brexit means that UK citizens can no longer simply move to Spain and start working remotely without considering immigration requirements.

Today, many British professionals use Spain's Digital Nomad Visa as a legal route to live in Spain while continuing to work for a UK employer.

Does Spain Allow UK Employees Under the Digital Nomad Visa?

Yes.

Spain's Digital Nomad Visa was created for people who work remotely for companies located outside Spain using computer and telecommunication systems.

The official Spanish government page for international teleworkers describes the route here: Ministry of Inclusion, Social Security and Migration — International Teleworkers.

This means both of the following structures may be possible:

• Employee of a UK company
• Self-employed professional or contractor

In other words, obtaining a Digital Nomad Visa does not automatically require becoming an autónomo.

The Biggest Misunderstanding: Social Security and Taxes Are Different

Many people assume that if they remain on UK payroll and continue paying UK National Insurance, Spain should not care.

That is not how the system works. Social Security and income tax are separate legal systems.

A person may remain covered by UK National Insurance while also becoming a Spanish tax resident.

The location of your employer, payroll or bank account does not automatically determine where income tax is due.

What Is an A1 Certificate?

An A1 Certificate is a document that confirms which country's Social Security system applies to a worker.

For UK employees moving to Spain, an A1 Certificate may allow them to remain in the UK National Insurance system instead of paying Spanish Social Security contributions.

HMRC explains the process for employees going to work in the EU, EEA or Switzerland here: Tell HMRC about employees going to work in the EU, EEA or Switzerland.

Can I Use an A1 Certificate After Brexit?

Yes.

Brexit did not eliminate Social Security coordination between the UK and Spain.

In many situations, UK employees can still obtain an A1 Certificate confirming that UK National Insurance remains applicable while working from Spain.

This is one of the main reasons why many British Digital Nomad Visa holders continue working for UK employers without immediately moving into the Spanish Social Security system.

Why Is the A1 Certificate So Important?

The Digital Nomad Visa itself is often the easy part.

The more difficult question is often where Social Security contributions should be paid.

If an A1 Certificate applies, the worker may remain within the UK National Insurance system.

This can significantly simplify the arrangement for both the employee and employer.

However, applicants should not assume that obtaining an A1 Certificate is automatic. Many applicants report delays when dealing with HMRC, so it is usually worth starting the process as early as possible.

An A1 Certificate is only one part of the Digital Nomad Visa process. In practice, many refusals and renewal problems arise because of Social Security history, expired A1 documents, employer changes, incomplete supporting evidence or outdated application requirements. For a broader discussion of these issues, see our guide on the biggest Digital Nomad Visa mistakes in 2026.

What Happens If I Cannot Get an A1 Certificate?

Many explanations jump directly from "no A1 Certificate" to "become an autónomo." Reality is more nuanced.

If UK Social Security coverage cannot continue, Spanish Social Security may become relevant.

At that point, there are usually two practical possibilities:

• Remain an employee and move into the Spanish Social Security system.
• Restructure the relationship and work as an autónomo.

The Three Most Common Real-World Scenarios

Scenario 1: Employee + A1 Certificate

In this scenario, the employee remains employed by the UK company, stays on UK payroll and continues UK National Insurance through the A1 Certificate.

The employee may still become a Spanish tax resident. Social Security and income tax are separate systems.

Scenario 2: Employee + Spanish Social Security

This scenario is frequently overlooked. Many people assume that if an A1 Certificate is not available, becoming autónomo is the only option.

That is not necessarily true.

The employee may remain employed by the UK company while becoming subject to the Spanish Social Security system.

What does this mean for the employer?

If Spanish Social Security applies, the employer may need to:

• Register with the Spanish Social Security authorities (TGSS).
• Obtain any required Spanish tax identification.
• Obtain a Contribution Account Code (CCC).
• Report employment information to the Spanish Social Security system.
• Pay employer Social Security contributions in Spain.
• Handle ongoing reporting and compliance obligations.

TGSS explains employer registration here: Spanish Social Security — Employer Registration.

The key point is that Spain focuses on employer registration and Social Security compliance, not simply whether the company has a Spanish subsidiary.

A UK company may not need to create a Spanish company, but it may still need to interact with Spanish Social Security authorities.

Why employers sometimes dislike this option

For large multinational companies, these requirements may be manageable.

For a smaller UK company with one employee moving to Spain, the administrative burden can be significant.

The issue is often not legality but practicality. Many employers simply do not want to deal with foreign payroll and Spanish Social Security compliance for a single employee.

Scenario 3: Contractor / Autónomo

This is one of the most common real-world solutions.

Instead of remaining an employee, the relationship becomes:

• UK company
• Independent contractor
• Autónomo in Spain

The company pays invoices. The worker manages Spanish taxes and Social Security directly.

Many Digital Nomad Visa holders choose this route because it is often the simplest structure for the employer.

One question many contractors overlook is what happens if the client relationship later ends. Unlike employees, autónomos do not automatically receive unemployment benefits. In Spain, they usually need to prove a legally protected situation of cese de actividad. We analyzed two recent High Court decisions explaining why many applications are rejected and what evidence courts considered persuasive. Read the full analysis.

This is also the path chosen by many digital nomads living in Spain. Instead of relying on a single employer, they build relationships with multiple international clients and companies. See our guide on how to find remote work while living in Spain.

If you decide to operate as a contractor, see our guide on how to register as an autónomo in Spain.

Does My Employer Need a Spanish Company?

Not necessarily.

Many people assume that a UK employer must open a Spanish company before an employee can live in Spain.

In reality, the more important question is often whether the employer is willing to deal with Spanish Social Security obligations if they become applicable.

The answer depends on:

• Whether an A1 Certificate applies.
• Whether Spanish Social Security becomes relevant.
• How long the employee intends to remain in Spain.
• The employer's willingness to handle compliance.

Will I Pay Tax in Spain or the UK?

Even if you remain in the UK National Insurance system through an A1 Certificate, you may still become a Spanish tax resident.

If you become a Spanish tax resident, Spain may tax your worldwide income.

Many British professionals focus only on visa requirements and tax residency, but the bigger question is often whether Spain or the UK is actually the better place to work as a freelancer or contractor.

The location of your bank account or payroll does not automatically determine where income tax is due.

Can I Pay UK National Insurance and Still Owe Tax in Spain?

Yes.

An A1 Certificate may help with Social Security obligations. It does not automatically remove Spanish income tax obligations.

A person may remain within the UK National Insurance system while simultaneously becoming liable for Spanish income tax.

Why Do Many Digital Nomad Visa Holders Become Autónomos?

Not because the law always requires it.

Many become autónomos because it is administratively simpler.

However, becoming an autónomo is not always the best financial choice. Depending on income level, pension goals and long-term plans, some professionals may find that remaining in the UK system is more attractive.

For a detailed comparison, see our guide on Spain vs UK for Freelancers.

Many professionals who relocate to Spain eventually move beyond a traditional employer-employee relationship and start working with international clients as contractors or consultants. If you are exploring remote opportunities outside your current employment, see our guide on finding remote work while living in Spain.

Instead of asking the employer to deal with Spanish Social Security registration, payroll obligations and reporting requirements, the worker manages those obligations directly.

If you become an autónomo in Spain, quarterly tax reporting may include Modelo 130 and Modelo 303 depending on your activity and VAT situation.

See our guides on Modelo 130 and Modelo 303.

Final thoughts

Brexit changed immigration rules, but it did not eliminate every mechanism that allows UK employees to continue working remotely from Spain.

The more important questions are whether you can obtain an A1 Certificate, where Social Security will be paid, whether your employer is willing to support the arrangement, and whether you will become a Spanish tax resident.

For some workers, the A1 Certificate route may work. For others, Spanish Social Security or an autónomo structure may be the more practical solution.
