Spain has a large freelance workforce that works as autónomos — but it also has one of Europe’s most aggressive crackdowns on “falso autónomo” (bogus self-employment). Engagements work well when the independence is genuine; the risk is real and expensive when it isn’t.
The autónomo model
A contractor registers with Hacienda (census via modelo 036 — the simplified 037 was abolished in Feb 2025) and with RETA, the special social-security regime, then invoices in their own name. Their burden:
- IRPF (progressive, up to ~47% with the regional surcharge), with quarterly prepayments (modelo 130).
- RETA social contributions at 31.5% (2026) on a base picked from 15 real-net-income brackets, with minimum bases of €653.59 to €1,928.10 a month (Orden PJC/297/2026, checked 2026-09-28); a reduced tarifa plana (~€80/month) applies for the first year of new autónomos.
- IVA at 21%, filed quarterly (modelo 303).
The contractor self-assesses everything; a foreign client withholds nothing (the IRPF retention on invoices applies only to Spanish payers).
The falso autónomo risk
Substance beats the contract. If the “contractor” works under the hirer’s direction, hours, tools and integration with no real business autonomy, the Inspección de Trabajo can reclassify to employment. Spain enforces this hard — especially after the 2021 “Rider Law” (Ley 12/2021) that presumes employment for delivery and distribution work managed through digital platforms (boe.es, checked 2026-09-28); an EU Platform Work Directive extends the logic (transposition due Dec 2026). Reclassification costs: back Seguridad Social (up to 4 years) with 100–150% penalties, plus LISOS fines up to €12,000 per worker and back holiday/extra pay. Note the TRADE figure (an autónomo economically dependent on one client for ≥75% of income) is a legitimate status with a registered contract — distinct from falso autónomo.
Contract and IP
- A written services agreement with genuine independence markers (own tools, own clients, own schedule, deliverable-based).
- IP assignment in writing. Under the Ley de Propiedad Intelectual (Art. 45), every assignment of economic rights must be in writing, express and time-limited; moral rights are inalienable. A US-style “work made for hire” clause alone is unreliable — assign economic rights explicitly.
Taxes and paperwork
Pay gross against invoices; no Spanish withholding for a foreign client. US payers collect a W-8BEN (W-8BEN-E for an SL) and file no 1099; services performed in Spain are foreign-source.

Contractor of Record in Spain
Given how hard Spain pursues falso autónomo, a Contractor of Record that signs with the autónomo and checks status reduces misclassification risk (whether any liability moves to it depends on the indemnification clause) — and for a full-time, single-client, directed role, an EOR is the clean route.
