How to Register as Autónomo in Spain

An autónomo is a self-employed worker registered in Spain's tax and social security system. The status allows you to legally invoice clients, access public healthcare, and build pension entitlements. It is the standard route for freelancers, consultants, and independent professionals operating in Spain.

Who can register as autónomo in Spain

Any adult with the legal right to work in Spain can register as autónomo. For non-Spanish nationals, this requires one of the following:

• Residence permit with work authorisation — Digital Nomad Visa, Cuenta Propia, Cuenta Ajena with self-employment permission
• Temporary protection — available to Ukrainian citizens (protección temporal) with the right to work
• EU/EEA citizenship — no additional permit required; register directly with a NIE

The essential prerequisite is a NIE (número de identidad de extranjero). Without it, registration is not possible.

Documents required before registration

Before filing your application, gather the following:

1. NIE and residence permit with work authorisation (original and copy)
2. Certificado digital — an electronic certificate for interacting with government agencies (obtain at sede.fnmt.gob.es)
3. Spanish bank account opened under your name and NIE (not your passport)
4. Código CNAE — the activity code for your profession (CNAE directory)
5. Tax regime decision — estimación directa (based on actual income) or módulos (fixed indicators)

Step-by-step registration process

Step 1. Register with AEAT (Agencia Tributaria)

File Modelo 036 — the declaration of commencement of economic activity. This form specifies:

• Your activity type (CNAE code) and description of services
• Tax regime (estimación directa or módulos)
• IVA and IRPF obligations
• Start date of activity

This can be filed online with your certificado digital, or your gestor can submit it on your behalf.

Step 2. Register with Seguridad Social

Within 30 days of registering with the AEAT, you must enrol with Seguridad Social under the RETA regime (Régimen Especial de Trabajadores Autónomos). This is where monthly social security contributions begin.

Registration is done through the Import@ss portal using your certificado digital or Cl@ve.

Step 3. Receive confirmation

Within 1–2 days you will receive:

• SMS and email from AEAT confirming your registration
• Notification from Seguridad Social confirming your enrolment in RETA
• Your social security number (NSS), if you did not have one previously

After registration: mandatory first steps

1. Set up DEHú — the electronic notifications system from government agencies (DEHú)
2. Verify your IBAN in your Seguridad Social account — ensure the correct bank account is listed for contribution debits
3. Download your Modelo 036 — your proof of registration with the AEAT
4. Understand invoicing requirements — all invoices must include IVA (21%) and, in some cases, IRPF withholding
5. Review the tax calendar — so you don't miss your first quarterly filing deadlines

Common questions when registering

Do I need to charge IVA?

Most autónomos must charge IVA at 21%. Exceptions include medical, educational, and certain insurance services. In the Canary Islands, IGIC (7%) applies instead of IVA.

When do I start paying taxes?

From the date of your AEAT registration. Your first quarterly filing covers the quarter in which you registered. For example, if you register in May, your first quarterly return covers Q2 (April–June) and must be filed by 20 July.

What if I had income before registering?

If you become a tax resident of Spain (living 183+ days per year), you are required to declare worldwide income for the entire calendar year — including income earned before registering as autónomo. Spain has double taxation treaties with over 90 countries (including the UK, US, Germany, France, and Ukraine) to prevent paying tax on the same income twice.

Can I work for my previous employer as autónomo?

Technically yes, but Spanish authorities may reclassify the arrangement as employment (falso autónomo) if you work exclusively for one client, follow their schedule, and use their equipment. This can result in penalties for both parties.
