Thinking of freelancing from Madrid, Málaga, or Mallorca? As autonomo in Spain you call the shots, invoice clients, and pay taxes straight to the government. Here’s the plain-English playbook: what it is, what you need, how to sign up, what it costs, and how to keep more of what you earn.
Autonomo in Spain explained
Autonomo = self-employed sole trader.
You bill under your own name, charge VAT (IVA) where required, and pay a monthly social-security quota plus quarterly taxes. No payroll department - just you and the tax forms.

What you need to set up as autónomo
Before you touch the first form, gather these six items:
- Passport photo page - clear colour scan or photo.
- Selfie holding that passport - identity check for the digital certificate.
- NIE certificate or TIE card - front and back images.
- Spanish IBAN bank account - the cuota will be auto-debited.
- Spanish mobile phone number - needed for SMS codes.
- Email address - where Hacienda and Seguridad Social will send notices.

Registration checklist
- Get a digital certificate (certificado digital) - download from FNMT, verify at a police station or online.
- Modelo 036 or 037 at the Tax Agency - declare your activity code (IAE), business start date, and VAT status.
- Register for the Social Security system (RETA) - within 30 days of step 2. Choose the income band that matches your expected profit.
- Activate direct debit (domiciliación) for your monthly quota and tax payments.
- Optional extras - open a dedicated business bank account, register a trade name, hire a gestoría if paperwork scares you.
