Legislative Changes as of July 1, 2023, Regarding Social Security for Home Office Workers in Spain
Where Do Home Office Workers Pay Social Security Contributions: Spain or the Employer’s Country?
The Covid-19 pandemic has led to an exponential increase in teleworking, significantly altering employer-employee relationships. As a result, labor legislation has had to adapt to these changes. Many employers and employees remain unaware of the applicable regulations, particularly when an employee moves to Spain to work remotely for an employer based abroad.
From an income tax perspective, double taxation agreements, typically based on the OECD Model Tax Convention, establish that salaries are generally taxable in the worker’s country of residence unless the work is performed in the employer’s country. For example, a German or French employee residing in Spain is subject to Spanish income tax unless part of their work is carried out in Germany or France. If such an employee travels back to their home country for three months to work, the German or French tax authorities may require income tax payments for that period.
Social Security Obligations: Three Possible Scenarios
- Employees Temporarily Assigned to Spain by Their Employer
If an employee has not moved to Spain voluntarily but has been sent by their employer to perform a specific task or serve a client, they will continue contributing to social security in their home country. In this case, the employee must submit:
- A declaration to the Spanish social security authorities indicating their personal details and the nature of their work in Spain.
- An A1 certificate issued by their home country’s social security system, proving continued contribution to their home country’s scheme.
This is in line with Article 12 of Regulation (EC) No. 883/2004, which states:
Article 12(1) – Special Rules A person who pursues an activity as an employed person in a Member State on behalf of an employer who normally carries out his activities there and who is sent by that employer to perform work on his behalf in another Member State shall remain subject to the legislation of the first Member State, provided that the foreseeable duration of such work does not exceed twenty-four months and that such person is not sent to replace another person.
Thus, employees can maintain their home country’s social security coverage as long as the assignment is temporary and circumstantial.
- Remote Workers Under the New Framework Agreement
The second and third cases arise from Regulation (EC) No. 883/2004, which was initially designed to regulate cross-border employment, including telework. A Framework Agreement on the application of Article 16(1) of the Regulation was signed by multiple European countries (including Spain, Germany, Switzerland, Austria, Belgium, France, and others), effective July 1, 2023. This agreement reinforces the “Lex Loci Laboris” principle, meaning that social security contributions are primarily due in the country where the work is performed.
Before the agreement, employees working more than 25% of their time in their country of residence were automatically required to contribute to that country’s social security system. The new agreement modifies this as follows:
- Employees working less than 25% of their time in their country of residence: Must contribute to social security exclusively in their employer’s country.
- Employees working between 25% and 50% of their time in their country of residence: May opt to continue contributing in their employer’s country for a maximum period of three years, with the possibility of an extension upon request.
- Employees Working Primarily from Spain (More Than 50%)
Employees who perform more than 50% of their work in their country of residence (e.g., Spain) are required to contribute to social security in that country. Many European employers mistakenly believe that workers residing in Spain can indefinitely maintain contributions in their home country using the A1 certificate. However, the A1 certificate is intended only for temporary assignments and does not apply when the worker intends to reside permanently in Spain.
Social Security Contributions for Non-EU Employees
For workers from non-EU countries, social security obligations depend on whether a bilateral or multilateral agreement exists between Spain and the worker’s home country. In the absence of such an agreement, employees may face the undesirable situation of being required to contribute to social security in both their home country and Spain.
Does Hiring an Employee in Spain Create a Permanent Establishment?
A frequent concern among employers is whether hiring a remote worker in Spain constitutes a permanent establishment (Betriebsstätte or Niederlassung), thereby triggering corporate tax obligations. In general, an employer does not create a permanent establishment in Spain solely by hiring an employee there. However, exceptions apply if the employer maintains a significant business presence in Spain, such as representatives with authority to negotiate and conclude contracts on behalf of the company.
Employer’s Obligations Regarding Spanish Income Tax Withholding
Employers without a permanent establishment in Spain are not required to withhold income tax from employees’ salaries, as confirmed by Spanish tax authorities in binding rulings V2223-22, V2614-22, and V2883-23. These rulings, based on Article 76 of the Spanish Income Tax Regulations (Royal Decree 439/2007), clarify that in the absence of a Spanish establishment, the employer does not need to withhold taxes.
However, this creates a potential risk for employees, as they receive their full salary without automatic tax deductions. They must ensure they save enough to meet their tax obligations when filing their annual income tax returns. To avoid financial strain, many companies and employees voluntarily withhold and prepay Spanish income tax on a monthly basis.
