A digital nomad application may look complete until someone reviews the Social Security evidence. The contract may already be signed and the income may be sufficient, yet the file still needs a defensible answer to three questions: who contributes, in which country, and on what legal basis?
Choose the contribution route early. Do not leave the Social Security evidence until the final week. Spain takes a different approach to employees and self-employed professionals. The official starting point is the UGE page for international teleworkers, together with its current documentary guidance.
Three possible routes
- An employee may need Spanish Social Security registration through the foreign employer.
- Foreign coverage may continue only if the applicable coordination rules support it and an acceptable certificate covers the work performed from Spain.
- A self-employed applicant should follow the RETA commitment required by the current UGE teleworker guidance.
First decide whether the applicant is employed or self-employed
The label used on an invoice or in an offer letter is not conclusive. An employee will normally work within an employer’s organisation and under its direction. A self-employed professional provides services on their own account and bears the commercial risk. Even ownership of a foreign company does not settle the issue when management powers and day-to-day work point in different directions.
Whichever classification applies, it must be consistent across the contract, company letter, immigration application, payroll and tax registrations. The international teleworker provisions of Law 14/2013 govern the legal route itself.

Route 1: the foreign employer registers in Spain
When Spanish Social Security legislation applies, a foreign employer can register as an employer and obtain a contribution account before registering the employee. As the Social Security administration explains, employer registration is the act through which the General Treasury assigns the identifying number used to control contribution obligations. The official employer registration guidance provides further details.
The steps for obtaining a Spanish tax number, arranging representation and setting up payroll depend on the employer’s structure. Social Security registration proves neither the existence nor the absence of a Spanish permanent establishment. Employment law, payroll withholding, Social Security and corporate tax each apply different tests and require separate review.
Route 2: an employee relies on foreign coverage
This option is available only if the applicable EU coordination rules or an international Social Security agreement support it, and the competent institution issues the required evidence. A contribution history, foreign payslip or private health policy cannot replace a certificate that determines the applicable legislation.
The certificate should be checked for the legal basis, the employer and employee, Spain as the country of work, the covered activity and the dates. An agreement only helps if the particular remote-working arrangement qualifies under it. Whether the relevant certificate can be issued under the applicable instrument is a matter for the competent institution.
The current UGE documentary sheet for employees requires either Spanish registration commitments or, when an agreement allows coverage to continue in the country of origin, the appropriate certificate. Immediately before filing, download the operative version from the official UGE teleworker page.
Route 3: the self-employed applicant commits to RETA
For applicants who provide services through a professional relationship, the current UGE information requires a commitment to register in Spain’s Special Scheme for Self-Employed Workers, RETA, after approval and before beginning the activity in Spain. This documentary position is specific to the immigration procedure. It should not be presented as a universal rule for every international Social Security agreement.
Timing, tax registration and the contribution position should be planned together. A freelance contract may support the immigration narrative, but if it conflicts with the registrations or the real working relationship, it creates avoidable risk.
The contract and company letter must tell the same story
Look at who directs the work, who bears the commercial risk, how long the relationship has existed, where the clients are and who is responsible for contributions. If a letter describes the applicant as an employee while the contract treats them as an independent supplier, the discrepancy requires an explanation. So does a nominal freelance arrangement in which one company controls the schedule, tools and pricing.
For professional activity, the current international teleworker rule permits work for companies in Spain up to 20% of total professional activity. Law 14/2013 sets this statutory limit. It belongs in the commercial forecast as well as the application.
Health cover and Social Security are different questions
Private health insurance does not remedy the absence of a valid Social Security route. Depending on the applicant’s Social Security position, the UGE file may also require evidence of health cover. The policy and the contribution analysis should be checked separately against the current official checklist.
Order of work
- Classify the relationship by reference to the actual working arrangements.
- Check the current UGE documentary sheet for that classification.
- Establish whether Spanish legislation or an international coordination instrument applies.
- Ask the competent institution whether it can issue the required certificate for work performed from Spain.
- If foreign coverage is not available, prepare the employer registration or RETA commitment, as applicable.
- Align the contract, company letter, Social Security evidence and filing dates.
- Review payroll, employment-law and permanent-establishment issues separately.
Frequently asked questions
Can the company simply keep paying contributions abroad?
No. That outcome must be supported by the applicable coordination rules and acceptable evidence from the competent institution.
Does Spanish employer registration automatically create a permanent establishment?
No automatic conclusion follows from registration alone. The tax analysis depends on the employee’s authority, activities, workplace and the applicable treaty.
Can every self-employed applicant rely on a foreign coverage certificate?
The current UGE teleworker guidance requires a RETA commitment for the professional-relationship route. Any interaction with an international agreement requires case-specific confirmation and should not be assumed.
