Freelance Services Agreement Spain (Acuerdo de Servicios Freelance)

A Freelance Services Agreement Spain (Acuerdo de Servicios Freelance) is a written contract between a self-employed professional (trabajador autónomo) and a client (cliente) establishing the terms under which independent professional services are rendered, governed principally by Ley 20/2007, de 11 de julio, del Estatuto del Trabajo Autónomo (LETA), and supplemented by the Código Civil Articles 1583 to 1587 on service contracts (contrato de servicios) and Articles 1544 to 1603 on contracts for work and services (contrato de obra). Article 11 of the LETA specifically regulates contracts for economically dependent self-employed workers (trabajadores autónomos económicamente dependientes — TRADE), imposing mandatory written form and enhanced protections.

The fundamental legal distinction between a freelance services agreement and an employment contract (contrato de trabajo) in Spain is the absence of the three defining characteristics of an employment relationship under Article 1.1 of the Estatuto de los Trabajadores (RDL 2/2015): personal work (trabajo personal), remuneration (retribución), and subordination under the employer's direction and control (dependencia y ajenidad). A freelance contract presupposes independence (independencia) and the worker's own organisation of time, methods, and resources. Spanish courts — principally the Sala de lo Social of the Tribunal Supremo — apply a multi-factor analysis examining the actual conduct of the parties rather than merely the contract's label, under the doctrine of primacía de la realidad (substance over form).

The LETA distinguishes between ordinary autónomos and TRADE workers. A TRADE worker is a self-employed professional who receives 75% or more of their annual income from a single client under Article 11.1 of the LETA. TRADE status confers statutory protections similar to employment: minimum 18 working days of annual leave, maximum 12 hours of effective daily activity, and the right to terminate the contract due to the client's serious breach without loss of pending fees. TRADE contracts must be registered with the Servicio Público de Empleo Estatal (SEPE) within 10 business days of execution.

All freelance professionals working in Spain must register in the Régimen Especial de Trabajadores Autónomos (RETA) of the Seguridad Social within 60 days before beginning their activity under Article 7.1.a) of the Ley General de la Seguridad Social (RDL 8/2015), and register their economic activity (alta en el Impuesto de Actividades Económicas — IAE) with the Agencia Tributaria. Freelancers must also file quarterly VAT declarations (Modelo 303) and income tax advance payments (Modelo 130 for direct estimation, or Modelo 131 for simplified objective estimation — módulos) under Ley 35/2006 del IRPF.

The Ley de Reformas Urgentes del Trabajo Autónomo (Ley 6/2017) and more recently Royal Decree-Law 13/2022 significantly modified the RETA contribution system, introducing the new cotización por ingresos reales (contribution based on actual net income) system progressively implemented from 2023, replacing the prior system of fixed base contributions. Under the new system, autónomos contribute based on their monthly estimated net income (rendimiento neto mensual) in one of 15 income brackets, with contributions ranging from €230 to €590 per month for 2024, and the ability to change brackets up to 6 times per year through the Import@ss system of the TGSS.

A Freelance Services Agreement Spain is required whenever a self-employed professional (autónomo) undertakes to provide services to a client on a project or ongoing basis, and the parties wish to document their commercial relationship, define deliverables, fees, and intellectual property rights, and protect themselves against disputes arising from scope, payment, or termination.

The agreement is needed when a creative professional — graphic designer, copywriter, photographer, web developer, or consultant — provides services to a Spanish company (sociedad limitada or sociedad anónima) and the client requires a written contract for accounts payable documentation, tax deductibility of fees under Ley 27/2014 del Impuesto sobre Sociedades, and proof of the independent (non-employment) nature of the relationship.

A Freelance Services Agreement is required when a foreign freelance professional provides services to a Spanish client remotely — the agreement establishes the applicable law (ley aplicable) and jurisdiction (fuero), typically Spanish courts under Reglamento (UE) 1215/2012 (Bruselas I bis) for EU-domiciled contractors, and documents the cross-border service for VAT purposes under the reverse charge mechanism (inversión del sujeto pasivo) under Article 69 of Ley 37/1992 del Impuesto sobre el Valor Añadido (IVA).

The agreement is needed when a TRADE (trabajador autónomo económicamente dependiente) relationship exists — where the freelancer derives 75% or more of income from one client — requiring mandatory written form and SEPE registration under Article 12 of Ley 20/2007. Without a signed written agreement, the TRADE worker cannot invoke statutory protections, and the Juzgado de lo Social may reclassify the relationship as employment.

A Freelance Services Agreement is required when the scope involves the creation of intellectual property — software, designs, written content, or audiovisual works — governed by Real Decreto Legislativo 1/1996 (Ley de Propiedad Intelectual — LPI). The agreement must explicitly address intellectual property assignment or licensing, as Spanish copyright law presumes that rights remain with the author unless expressly transferred in writing under Article 43 LPI.

The agreement is also needed for platform workers (trabajadores de plataformas digitales) to document services rendered through digital delivery platforms, particularly following Ley Rider (Real Decreto-Ley 9/2021), which created a rebuttable presumption of employment for delivery platform workers — a clear, properly structured freelance agreement with genuine independence evidence helps rebut this presumption where the relationship is truly autonomous.

Under the Estatuto de los Trabajadores (ET) RDL 2/2015, Spanish employment law governs contracts, dismissals, and working conditions. The Tesorería General de la Seguridad Social (TGSS) administers social security contributions. The Servicio Público de Empleo Estatal (SEPE) manages unemployment benefits. The Inspección de Trabajo y Seguridad Social enforces labour compliance. The Juzgados de lo Social hear employment disputes under the Ley Reguladora de la Jurisdicción Social (Ley 36/2011).

A valid Freelance Services Agreement Spain under Ley 20/2007 del Estatuto del Trabajo Autónomo and the Código Civil must contain the following essential elements.

Identification of Parties: Full legal name, DNI/NIE/NIF, and registered address of the freelancer (autónomo) and the client. For the autónomo, include the RETA affiliation number (número de afiliación a la Seguridad Social), IAE activity code (epígrafe del IAE), and, if VAT-registered, the NIF-IVA. For the client, include the NIF and Registro Mercantil registration details if a legal entity.

Scope of Services: A precise description of the services to be provided (objeto del contrato) — deliverables, technical specifications, quality standards, and exclusions from scope. Vague scope definitions are a primary source of disputes in freelance relationships — the Código Civil Article 1261 requires a specific, determinate object (objeto determinado) for the contract to be valid. For TRADE contracts, the description must reflect the independence and organisational autonomy of the worker.

Fees and Payment Terms: The agreed fees (honorarios) — fixed project fee (precio cerrado), hourly rate (tarifa horaria), or retainer (tarifa de retención mensual) — the payment schedule (calendario de pagos), acceptable payment methods, and the applicable late payment interest rate. Late payment in commercial transactions (transacciones comerciales) between professionals is governed by Ley 3/2004, de 29 de diciembre, por la que se establecen medidas de lucha contra la morosidad en las operaciones comerciales — the legal default interest rate is 8 percentage points above the European Central Bank reference rate (tipo de interés del BCE).

VAT and Tax Treatment: Whether fees are quoted including or excluding VAT (IVA), the applicable VAT rate (21% for most professional services under Ley 37/1992), and the client's obligation to apply withholding tax (retención de IRPF) at 15% on fees paid to autónomos (7% for newly registered autónomos in their first three years) under Article 95 of the IRPF Reglamento (Real Decreto 439/2007). The invoice (factura) requirements under Real Decreto 1619/2012 (Reglamento de Facturación) must be observed.

Deliverables and Deadlines: Specific deliverables (entregables) with agreed deadlines, milestone schedule (hitos de entrega), acceptance procedure (procedimiento de aceptación), and the consequences of delays attributable to either party. For fixed-price contracts (contratos de precio cerrado), a clear variation order procedure prevents scope creep.

Independence Provisions: Express acknowledgment that the autónomo provides services independently (de forma autónoma e independiente), organises their own working time and methods, uses their own tools and equipment, and is not subject to the client's organisational authority. These provisions are critical to substantiate the non-employment nature of the relationship before the Inspección de Trabajo y Seguridad Social (ITSS) and the Juzgado de lo Social.

Intellectual Property: Assignment or licensing of intellectual property rights (derechos de propiedad intelectual) in works created under the agreement, specifying the scope, territory, and duration of any licence. Under Article 43 of the Ley de Propiedad Intelectual (RDL 1/1996), assignments must be in writing and may only cover rights known at the time of the assignment.

Confidentiality: An obligation of professional confidentiality (confidencialidad) covering the client's business information, trade secrets, and data, with a defined survival period after contract termination. Trade secrets are protected under Ley 1/2019, de 20 de febrero, de Secretos Empresariales, transposing Directiva 2016/943/UE.

Termination: Grounds for termination (causas de resolución) by each party — including material breach, insolvency, and convenience termination with notice — the applicable notice period, and consequences of early termination (fees for completed work, return of materials). For TRADE workers, Article 15 of Ley 20/2007 establishes minimum termination notice requirements.

Dispute Resolution: Applicable law (Spanish law), jurisdiction (Spanish courts — Juzgados de lo Mercantil for commercial disputes, Juzgados de lo Social for reclassification disputes), and any agreed alternative dispute resolution mechanism (mediación, arbitraje).
