1 - What Are Your Work Structure Options in Spain?
When working from Spain as a freelancer, contractor or remote worker — or when a foreign company wants to engage a worker in Spain without direct employment — there are four main structures to consider: umbrella company, contractor setup, autónomo (self-employment), and EOR (Employer of Record).
Each structure has different implications for tax, social security, worker classification, invoicing, liability and compliance. Choosing the wrong structure — or defaulting to autónomo without assessing the relationship — can result in misclassification penalties, back social security payments, or loss of Beckham Law eligibility.
ApexTax helps individuals and companies assess which structure is most appropriate for their specific situation before committing to a provider or registration.
2 - The Four Main Structures: Autónomo, Umbrella, Contractor SL & EOR
Autónomo (self-employed / sole trader). The most common structure for freelancers in Spain. You register with the RETA (Régimen Especial de Trabajadores Autónomos), invoice clients directly, and pay self-employment social security contributions based on a 15-bracket income-based system (since 2023). Monthly contributions range from approximately €230 (for incomes under €670/month) to €530 (for incomes over €6,000/month). A 'tarifa plana' of €80/month applies to new autónomos in their first year. Income is taxed at progressive rates. Risk: if you invoice only one or two clients who exercise strong control over your work, Spanish authorities may reclassify the relationship as employment — with significant back-payment consequences.
Umbrella company. You work through a Spanish umbrella company, which employs you, invoices your clients on your behalf, and processes payroll. You receive a salary net of tax and social security. Simpler than autónomo registration, but umbrella fees reduce net income. The umbrella must be genuinely compliant — some umbrella structures in Spain carry legal risks if not set up correctly.
Contractor company (SL). You incorporate a Spanish limited company (Sociedad Limitada) through which you invoice clients and pay yourself a combination of salary and dividends. Offers greater tax planning flexibility for higher earners, but involves company setup costs, ongoing accounting and administration obligations, and is generally only efficient above approximately €60,000–80,000 annual turnover.
EOR (Employer of Record). A third-party company employs you in Spain on behalf of your actual working company or client. Provides full employment contract, payroll and social security coverage. More expensive than autónomo but provides legal clarity where the working relationship is closer to employment than independent contracting.
3 - Key Risks: Misclassification, Social Security & VAT
Worker misclassification risk. Spanish labour law applies a rebuttable presumption of employment when a worker has the characteristics of an employee: exclusivity or near-exclusivity, fixed working hours, use of the client's tools and equipment, integration into the client's organisation, and inability to subcontract. Registering as autónomo does not eliminate this risk — it simply shifts the burden of proof. The Spanish Social Security Inspectorate actively audits misclassification, particularly in technology, consulting and remote work sectors.
Social security obligations. All working structures in Spain involve mandatory social security contributions. Autónomos pay RETA contributions directly based on their declared net income bracket. Umbrella employees and EOR employees have contributions deducted and paid by the employer. Contractor companies pay both employer (approximately 30–32%) and employee contributions for any directors on payroll. There is no legal way to operate in Spain commercially without social security coverage.
VAT (IVA) and invoicing. Autónomos and contractor companies must register for Spanish VAT and include IVA on invoices to Spanish-based clients (currently 21% general rate). Invoices to non-Spanish EU clients or non-EU clients are typically zero-rated under reverse charge rules — but the administration and quarterly reporting obligations remain.
4 - Which Structure Is Right for You?
The right structure depends on several factors assessed together:
Choose autónomo if: you have multiple independent clients; you control your own working hours and methods; your Spanish clients represent less than 80% of income; and your annual income is below approximately €60,000 (above this, a contractor SL may be more tax-efficient).
Choose umbrella if: you want to avoid the administrative burden of autónomo registration; you are working in Spain on a short-to-medium term project; or your client requires you to have a Spanish employment contract but EOR is not available.
Choose contractor SL if: your annual revenue exceeds approximately €60,000–80,000; you want salary and dividend flexibility; and you are committed to Spain as a long-term base.
Choose EOR if: the working relationship is genuinely employment-like; the client company requires a Spanish employment structure; or you need Spanish employment status for visa or Beckham Law purposes.
Beckham Law note: autónomos are generally not eligible for the Beckham Law regime unless they qualify under the highly qualified professional or startup founder routes. Employees — including EOR and umbrella employees with the right structure — may be eligible. This is a critical consideration for high earners planning a Spain relocation.
