Key Takeaways
- Autónomo recurring costs: €80/month initially, then €230–€530/month in RETA social security contributions once the tarifa plana discount ends — plus €50–€150/month gestoría and quarterly IRPF advances on profit.
- SL costs more to start and run. Formation typically runs €4,000–€4,500 all-in; ongoing accounting and filings cost €250–€500/month — making an SL uneconomical until income (and retained earnings) justify the overhead.
- The hidden costs expats underestimate: staying in the wrong structure for 12–24 months (inertia cost), time lost to language barriers, and mid-year gestoría switching costs — predictable cost matters more than minimum cost.

Autónomo cost stack (typical)
- Social security: €80/month initially → later €230–€530/month
- Gestoría: €50–€150/month
- Quarterly tax advances: depends on profit
- Optional tools: invoicing software, bookkeeping
Second-order effect: even if taxes are manageable, the timing of payments changes how you manage cash.
SL cost stack (typical)
- Setup: €4,000–€4,500
- Ongoing admin: €250–€500/month
- Corporate bank account fees (varies)
SL becomes rational when retained earnings or liability separation matter.
The hidden costs expats miss
- Inertia costs (staying in the wrong structure for 12–24 months)
- Language costs (time lost translating and misunderstanding)
- Switching costs (changing gestoría mid-year)

Frequently Asked Questions
Do I need a gestor for this process?
For most administrative procedures in Spain, a gestor simplifies the process significantly. They handle paperwork, book appointments, and know the practical requirements that websites often do not mention. Fees typically range from EUR 50-150 per procedure.
What documents do I need?
At minimum, you will need your NIE (or passport for initial procedures), proof of address (padron certificate or utility bill), and documentation specific to the procedure. Always bring originals and copies of everything.
How long does this process take?
Processing times vary by office and procedure. Simple administrative tasks take days to weeks. Residency, tax, and property matters can take weeks to months. Having all documentation correct from the start prevents delays.
Where can I get help in English?
English-speaking gestoria offices on the Costa del Sol handle most expat administrative needs. See our guide to English-speaking gestorias for recommendations. Many town halls in tourist areas also have some English-speaking staff.
