Key Takeaways
- Under ~€50k net profit: autónomo usually wins. Simpler administration and no setup costs outweigh any tax advantage from incorporating — especially if you need to extract most income to live.
- Over ~€80k (with retained earnings): SL often wins. Corporate tax on retained profits can be significantly lower than personal IRPF rates of up to 47% — but only if you’re not extracting everything annually, which narrows the gap.
- The €50k–€80k band needs a model, not a rule. SL setup runs ~€4,000–€4,500 and ongoing admin ~€250–€500/month; only an advisor running your specific numbers can confirm whether the tax saving exceeds the overhead cost in your situation.

The right question isn’t “which pays less tax?” It’s:
- Do you need to extract all profits personally?
- Can you tolerate extra admin?
- Do you need liability separation?
- Are you planning to stay in Spain long enough for the structure to pay back?

Quick framework
Autónomo usually wins when
- net profit is under ~€50k/year
- you need to extract most income to live
- you want minimal structure complexity
SL often wins when
- net profit is above ~€80k/year
- you can retain 30%+ inside the company
- you want liability separation
- you want to reinvest (equipment, marketing, hiring)
The middle band (€50k–€80k) is where you should model it with an advisor.
The second-order truth: SL savings come from retained earnings
If you extract everything every year, the SL advantage narrows.
If you retain earnings for 2–3 years, corporate tax treatment becomes meaningful.
Liability (often ignored)
Autónomo can expose personal assets to business risk.
If you sign large contracts, work with subcontractors, or have penalty clauses, SL can be justified earlier than tax math suggests.

Frequently Asked Questions
How much does it cost to be autonomo in Spain?
Monthly social security starts at approximately EUR 230 under the 2026 income-based quota system. Add quarterly tax filing costs (EUR 50-100 if using a gestor) and you are looking at EUR 300-400 per month minimum in fixed costs before you earn anything.
Can I be autonomo with foreign clients only?
Yes. Many expats on the Costa del Sol work as autonomos serving clients outside Spain. You still pay Spanish social security and taxes, but may benefit from reduced VAT obligations on services exported outside the EU.
What is the tarifa plana for new autonomos?
New self-employed workers can pay a reduced social security rate of EUR 80 per month for the first 12 months, extendable to 24 months if income remains below the minimum wage. This significantly reduces startup costs.
Do I need a gestor to be autonomo?
Technically no, but practically yes. Quarterly tax filings (Modelo 130, 303) and annual declarations require specific knowledge. A gestor costs EUR 60-120 per month for ongoing autonomo management. The cost of getting it wrong (penalties, interest) far exceeds the gestor fee.
What is the difference between autonomo and SL?
Autonomo is simpler (no minimum capital, easier setup) but you have unlimited personal liability. An SL (Sociedad Limitada) requires EUR 3,000 minimum capital and more administration but limits your liability to the company assets. Most solo operators start as autonomo and incorporate later if needed.
