Autónomo in Spain 2026: Self-Employment Guide

Complete guide to becoming autónomo in Spain: registration, progressive contributions, quarterly taxes, tarifa plana, and autónomo vs SL comparison.

Working as an autónomo (self-employed worker or freelancer) in Spain is the most common route for expats who want to run their own business, consult independently, or freelance from Spanish territory. With roughly 3.3 million registered self-employed workers, the trabajador autónomo is a cornerstone of the Spanish economy. However, the legal framework has undergone significant changes since 2023, most notably the introduction of a progressive contribution system based on real income. This guide covers everything you need to know about becoming and operating as an autónomo in Spain in 2026 — from registration to taxes, deductions, and how self-employment interacts with the Beckham Law and the digital nomad visa.

What Is an Autónomo and Who Needs to Register?

An autónomo (formally, trabajador por cuenta propia) is any individual who regularly performs an economic or professional activity for profit without being employed under someone else's contract. The legal framework is governed by the Ley 20/2007, de 11 de julio, del Estatuto del trabajo autónomo (the Self-Employed Workers' Statute).

You must register as autónomo if you meet any of the following criteria:

• You invoice clients regularly — even if you invoice only one client, regularity triggers the obligation.
• You earn above the SMI threshold — the Salario Mínimo Interprofesional for 2025 is EUR 15,876 annually (EUR 1,134/month in 14 payments). Earning above this amount from self-employed activity makes registration mandatory.
• You perform a professional activity requiring IAE registration — any activity classified under the Impuesto de Actividades Económicas codes that you perform habitually.

Foreign nationals need a valid NIE number and a work authorization (either EU citizenship, a residence-and-work permit, or a digital nomad visa) before they can register. Non-EU nationals who have obtained their residence authorization should also apply for a TIE card (Tarjeta de Identidad de Extranjero), which serves as the physical proof of legal residence and is required for many administrative procedures.

How to Register as Autónomo: Step by Step

The registration process involves two government bodies: the Agencia Estatal de Administración Tributaria (AEAT — the Tax Agency) and the Tesorería General de la Seguridad Social (TGSS — Social Security). Both steps can be completed online the same day if you have a digital certificate or Cl@ve PIN.

Step 1: Obtain Digital Authentication

Before anything else, activate your certificado digital from the FNMT or your Cl@ve PIN. These are required to access both the AEAT and TGSS online portals. EU citizens can also use their national eID in many cases.

Step 2: Register with the Tax Agency (AEAT)

Submit Modelo 036 — the Declaración censal de alta — before your first day of activity. As of February 2025, the simplified Modelo 037 has been discontinued and all taxpayers must use the full Modelo 036.

In this form you will:

• Declare your activity start date
• Choose your epígrafe (activity code) under the IAE classification
• Select your IVA (VAT) regime — most freelancers use the régimen general
• Select your IRPF regime — typically estimación directa simplificada (simplified direct estimation)

Step 3: Register with Social Security (RETA)

Within 60 days before your start date (or on the same day), enrol as a trabajador autónomo in the Régimen Especial de Trabajadores Autónomos (RETA) through the TGSS Import@ss portal. During registration you will:

• Forecast your expected net monthly income for the year
• This forecast determines your initial contribution bracket (tramo) and monthly payment
• You can adjust your declared income up to six times per year if circumstances change

Step 4: Complementary Registrations

Depending on your activity, you may also need to:

• Register with your local Ayuntamiento for an opening license (licencia de apertura) if you have physical premises
• Register with the relevant professional colegio if your profession is regulated (architects, lawyers, healthcare professionals)
• Obtain data protection compliance through the AEPD if you handle personal data

The New Progressive Contribution System (2023-2031)

The most consequential reform for autónomos in recent years was introduced by Real Decreto-ley 13/2022, de 26 de julio, which replaced the old system where self-employed workers could freely choose their contribution base regardless of income. The new system phases in progressively from 2023 to 2031, with contributions tied to rendimientos netos (real net income).

How It Works

Your net monthly income (gross income minus deductible expenses, with an additional 7% flat-rate deduction for general expenses) determines which of 15 income brackets (tramos) you fall into. Each bracket has a minimum and maximum contribution base, and the standard contribution rate of 31.40% is applied to your base.

Key Contribution Brackets (2025-2026 Rates)

Here are selected brackets to illustrate the progressive structure:

Net Monthly Income	Min. Contribution Base	Approx. Monthly Quota
Up to EUR 670	EUR 653.59	~EUR 205
EUR 670 - 900	EUR 718.95	~EUR 226
EUR 900 - 1,166.70	EUR 849.67	~EUR 267
EUR 1,166.70 - 1,300	EUR 950.98	~EUR 299
EUR 1,300 - 1,500	EUR 960.78	~EUR 302
EUR 1,500 - 1,700	EUR 960.78	~EUR 302
EUR 1,700 - 1,850	EUR 1,143.79	~EUR 359
EUR 1,850 - 2,030	EUR 1,209.15	~EUR 380
EUR 2,030 - 2,330	EUR 1,274.51	~EUR 400
EUR 2,330 - 2,760	EUR 1,372.55	~EUR 431
EUR 2,760 - 3,190	EUR 1,470.59	~EUR 462
EUR 3,190 - 3,620	EUR 1,568.63	~EUR 493
EUR 3,620 - 4,050	EUR 1,666.67	~EUR 523
EUR 4,050 - 6,000	EUR 1,764.71	~EUR 554
Above EUR 6,000	EUR 1,872.55	~EUR 588

At year-end, the Seguridad Social compares your actual net income (from your tax return) with your declared forecast. If you underpaid, you will receive a supplementary bill; if you overpaid, you receive a refund.

Tarifa Plana: Reduced Rate for New Autónomos

One of the most valuable incentives for new self-employed workers is the tarifa plana — a flat reduced rate that significantly lowers the cost of entry.

• First 12 months: EUR 80/month (plus the Mecanismo de Equidad Intergeneracional surcharge of 0.9% in 2026, adding roughly EUR 5-6)
• Months 13 to 24: The EUR 80/month rate can be extended for a second year if your net annual income stayed below the SMI threshold (EUR 16,576 annually for 2025 reference). This extension is not automatic — you must file for it within one month after the first year ends.
• Months 25 to 36: If income remains below the SMI, some autonomous communities offer additional regional discounts.

Eligibility: You must be registering for the first time, or at least 2 years must have passed since your last RETA registration (3 years if you claimed tarifa plana before). You cannot have outstanding debts with Social Security or the Tax Agency.

Autónomos with a recognized disability of 33% or more, victims of gender violence, or victims of terrorism can claim the EUR 80 flat rate for the first 24 months regardless of income.

Quarterly Tax Obligations

As an autónomo, you interact with the AEAT on a quarterly cycle. The four key filing obligations are:

Modelo 303 — Quarterly VAT (IVA) Return

You must file Modelo 303 every quarter to declare the IVA you charged on your invoices (IVA repercutido) minus the IVA you paid on business purchases (IVA soportado). The standard IVA rate is 21%. If the balance is positive, you pay the difference to the AEAT. If negative, you can carry the credit forward or claim a refund in the Q4 filing.

Modelo 130 — Quarterly IRPF Prepayment

Under the estimación directa regime, you file Modelo 130 each quarter to make a 20% advance payment on your net profit (revenue minus deductible expenses for that quarter). These prepayments are credited against your annual income tax return (Modelo 100, Declaración de la Renta).

Filing Deadlines

Quarter	Period	Filing Deadline
Q1	January - March	1-20 April
Q2	April - June	1-20 July
Q3	July - September	1-20 October
Q4	October - December	1-30 January (following year)

Annual Declarations

In addition to quarterly filings, autónomos must submit:

• Modelo 390 — Annual VAT summary (January)
• Modelo 100 — Annual income tax return (Declaración de la Renta, April-June)
• Modelo 347 — Annual declaration of operations with third parties exceeding EUR 3,005.06 (February)
• Modelo 720 — Annual declaration of overseas assets exceeding EUR 50,000 per category (March)
• Modelo 349 — Recapitulative statement of intra-EU operations (if applicable)

Deductible Expenses for Autónomos

Properly tracking deductible expenses is critical because they reduce both your IRPF tax base and your Social Security contributions (since contributions are now based on net income). For an expense to be deductible, it must be directly related to your professional activity and supported by a valid invoice.

Commonly Deductible Expenses

• Social Security contributions — Your cuota de autónomos is fully deductible
• Accounting and legal fees — Gestoría, asesoría, and lawyer fees related to your business
• Office space — Rent, coworking memberships, or a proportional percentage of your home if you register a home office with the AEAT
• Home office supplies — If your home office is registered, you can deduct 30% of the proportional share of utility bills (electricity, water, gas, internet) based on the ratio of office space to total home area
• Professional insurance — Civil liability, professional indemnity, and similar policies
• Health insurance — Up to EUR 500/year per insured person (yourself, spouse, and children under 25)
• Training and education — Courses, conferences, books, and subscriptions directly related to your activity
• Travel and meals — Transport, accommodation, and per-diem meal allowances (EUR 26.67/day within Spain, EUR 48.08/day abroad) when justified by business travel
• Vehicle expenses — 50% of fuel, maintenance, insurance, and depreciation if the vehicle is used for mixed personal/business purposes (100% if exclusively for business, but this is difficult to prove)
• Marketing and advertising — Website hosting, domain names, online advertising, business cards, and promotional materials
• Software and subscriptions — Tools, platforms, and SaaS products used for your business
• Bank fees — Charges on your business bank account
• Depreciation — Amortization of equipment, computers, furniture at rates set by AEAT tables

Autónomo vs Sociedad Limitada (SL)

One of the most common questions from expats earning above a certain threshold is whether to stay as an autónomo or incorporate a Sociedad Limitada (SL). Here is a detailed comparison:

The general rule of thumb: when your recurring annual net profit consistently exceeds EUR 40,000 to EUR 50,000, the flat 25% corporate tax rate of an SL (or 15% in the first two years) becomes more efficient than paying IRPF at marginal rates of 37% or higher. However, incorporating adds complexity and costs, so the decision should factor in liability concerns, growth plans, and whether you need to reinvest profits in the business. Consult a qualified asesor fiscal before making this decision.

Note that once you are tax resident in Spain (spending more than 183 days per year in Spanish territory), you are liable for IRPF on your worldwide income regardless of whether you operate as autónomo or through an SL. If you hold assets abroad, you may also need to file Modelo 720. Additionally, high-net-worth autónomos should be aware of the wealth tax (Impuesto sobre el Patrimonio), which applies to net assets exceeding the exempt threshold. If you earn income from countries with which Spain has a double taxation treaty, those agreements can help you avoid being taxed twice on the same income.

The Beckham Law and Self-Employment

A common misconception among expats is that they can combine autónomo status with the Beckham Law flat 24% tax rate. In most cases, this is not possible.

The Beckham Law (formally, the Régimen Especial de Impatriados under Article 93 of the LIRPF) was designed primarily for employed workers, company directors, and specific categories introduced by Ley 28/2022 (the Startup Law). Classic autónomos who offer services to multiple clients are explicitly excluded.

Limited Exceptions

There are narrow exceptions where self-employed activity can qualify:

1. Startup founders — If you found an empresa emergente (startup) certified by ENISA, you can qualify even if you hold 100% of the shares and are registered as autónomo societario.
2. Highly qualified professionals serving startups — Professionals providing services to certified startups in training, research, development, or innovation (R&D&I), where at least 40% of income derives from these activities.
3. Innovative solo entrepreneurs — Individual entrepreneurs whose venture is certified as innovative by ENISA before the move to Spain.

Digital Nomad Visa Holders

If you arrive in Spain on a digital nomad visa and work remotely for a foreign employer, you may qualify for the Beckham Law. However, if you register as autónomo to invoice Spanish clients or perform local freelance work, you fall outside the Beckham Law scope and will be taxed under the standard IRPF progressive scale. This distinction is critical for tax planning — discuss your specific situation with a tax advisor before choosing your path.

Social Security Benefits

Registering with RETA and paying your cuota de autónomos gives you access to the Spanish social security system, which provides:

• Public healthcare — Full access to the Spanish national health system (SNS) for you and your dependents
• Sick leave (incapacidad temporal) — From the 4th day of illness (the first 3 days are uncovered), you receive approximately 60% of your contribution base, rising to 75% from day 21
• Maternity and paternity leave — 16 weeks at 100% of your contribution base
• Cessation of activity (cese de actividad) — The autónomo equivalent of unemployment benefit, available if your business closes involuntarily. Requires a minimum of 12 months of contributions.
• Retirement pension — Based on your contribution history and base, integrated into the general Spanish pension system
• Professional accident coverage — Through a Mutua colaboradora that you select at registration

Practical Tips for Expat Autónomos

1. Hire a gestoría from day one — A gestoría or asesoría fiscal (tax advisory firm) costs EUR 50-100/month and handles your quarterly filings, annual return, and Social Security adjustments. The fees are fully deductible and the peace of mind is invaluable.

2. Open a dedicated business bank account — While not legally required, separating personal and business finances dramatically simplifies expense tracking and tax deductions.

3. Keep every invoice — Spanish tax law requires you to retain all invoices and receipts for at least 4 years (the statute of limitations for tax audits). Digital copies are acceptable.

4. Forecast your income carefully — Under the new system, significantly underestimating your income means a large supplementary Social Security bill at year-end. Overestimating means tying up cash unnecessarily. Review and adjust your forecast regularly using the six annual windows.

5. Consider the tarifa plana timing — If you plan to start freelancing, time your RETA registration to maximize the 12-month discount window. Starting mid-year means you lose months of the benefit.

Frequently Asked Questions

Can I be employed and autónomo at the same time in Spain?

Yes, this is called pluriactividad. If you have a salaried job and also perform freelance work, you must register with both the Régimen General (through your employer) and RETA. The good news is that in situations of pluriactividad, you may be entitled to a reduction in your autónomo Social Security contributions of up to 50% during the first 18 months and 25% for the following 18 months, to avoid double-paying into the system.

What happens if I earn very little — do I still need to register?

Spanish law requires registration when the activity is habitual. The courts have generally interpreted habitual activity as earning above the SMI (approximately EUR 1,134/month in 2025). If you earn below this threshold occasionally and irregularly, you may not need to register, but this is a grey area. Many tax advisors recommend registering anyway to access healthcare and avoid potential sanctions. Penalties for working without RETA registration can reach EUR 12,000 or more.

How does the annual income regularization work under the new system?

At the end of each fiscal year, the Seguridad Social cross-references your actual net income (from your tax return filed with the AEAT) against the forecast income you declared during the year. If your real income was higher than declared, you receive a supplementary contribution bill. If it was lower, you receive a refund. This regularization typically occurs in the second half of the year following the tax period. You can minimize surprises by updating your income forecast proactively through the Import@ss portal.

Can I register as autónomo on a non-lucrative visa?

No. The visado de residencia no lucrativa explicitly prohibits any work activity in Spain, whether employed or self-employed. To work as autónomo, you need either EU/EEA citizenship, a residence and work permit (cuenta propia), a digital nomad visa, or authorization under the startup law. Violating the terms of a non-lucrative visa can result in its revocation.

What is the TRADE status for autónomos?

A Trabajador Autónomo Económicamente Dependiente (TRADE) is an autónomo who derives at least 75% of income from a single client. TRADEs have additional protections under the Estatuto del trabajo autónomo, including the right to a written contract with their main client, 18 working days of annual leave, and protections against unjustified contract termination. If you meet this threshold, you should formalize TRADE status, as failing to do so can create legal complications for both you and your client.
