What is an Autónomo?
An autónomo (also called trabajador autónomo or trabajador por cuenta propia) is a self-employed person in Spain. This includes freelancers, consultants, independent contractors, and anyone running their own business as a sole trader.
If you're an expat working remotely for foreign clients while living in Spain, or offering services locally, you'll likely need to register as autónomo and handle quarterly tax filings.

How to Register as Autónomo
Becoming autónomo requires registering with two separate government bodies:
Get Your Digital Certificate
Request a Certificado Digital from FNMT (fábrica de moneda). This is your electronic signature for all government dealings. You'll need to verify your identity at a government office.
Register with Hacienda (Tax Agency)
File Modelo 036 (or simplified 037) on the Agencia Tributaria website to declare your professional activity. Choose your IAE code (epígrafe) - this determines your activity type and VAT obligations.
Enroll in Social Security (RETA)
Register with the Régimen Especial de Trabajadores Autónomos on the Social Security website within 60 days of your Hacienda registration. Declare your estimated annual earnings to determine your contribution tier.
Tip: Many expats hire a gestor (administrative agent) to handle registration. It typically costs €100-200 and saves significant time navigating Spanish bureaucracy.
Quarterly Tax Obligations
As an autónomo, you don't just file once a year. You must submit quarterly tax declarations:
Forms You'll File Every Quarter
Modelo 303
Quarterly VAT (IVA)
Report the 21% IVA you charged on invoices minus the IVA you paid on business expenses.

Pay 20% of your quarterly net profit (income minus expenses) as an advance on your annual income tax.

Social Security (Cuota de Autónomo)
Since 2023, Spain uses an income-based system for autónomo contributions. You pay based on your actual earnings, divided into 15 brackets:
| Net Income (Annual) | Monthly Contribution |
|---|---|
| Up to €670/month | €230 |
| €670 - €1,300/month | €260 - €290 |
| €1,300 - €2,500/month | €290 - €350 |
| €2,500 - €4,050/month | €350 - €450 |
| Above €6,000/month | €530 max |
Tarifa Plana: €80/month for New Autónomos
First-time autónomos pay just €80/month for the first 12 months. Can be extended another 12 months if income stays below minimum wage.
This covers: Public healthcare, 16 weeks paid parental leave, pension rights, up to 12 months unemployment (after 1 year contributing)
Deductible Expenses
One advantage of being autónomo: you can deduct legitimate business expenses from your taxable income. This reduces both your quarterly IRPF payments and annual tax bill.
Commonly Deductible
- • Home office (proportional rent, utilities, internet)
- • Professional software subscriptions
- • Computer & equipment
- • Training & conferences related to work
- • Accountant (gestor) fees
- • Travel for business purposes
- • Per-diem meals while traveling (€26.67/day in Spain)
- • Private health insurance (up to €500/person)
Partially Deductible
- • Vehicle expenses (50% if mixed personal/business use)
- • Mobile phone (% used for business)
- • Coworking space membership
- • Bank fees on business account
- • Professional liability insurance
- • Advertising & marketing costs
Keep receipts! Hacienda may request proof of expenses during an audit. Digital copies are valid - many autónomos use expense tracking apps.
Key 2025 Changes for Autónomos
All autónomos must file annual tax return
Previously only required if earning €1,000+. Now mandatory regardless of income.
VAT exemption for small businesses
Under €85,000 annual revenue? You may be exempt from quarterly VAT declarations (EU Directive 2020/285).
Income-based contributions fully implemented
The 15-bracket system is now fully in place. You pay based on actual earnings, not a flat rate.
