Overview

Working legally as a freelancer in Spain requires registering as autónomo — both with the Agencia Tributaria (tax authority) and Social Security. This applies whether your clients are Spanish or abroad.

Requirements

Your visa/residency status must permit self-employment (not all categories do)
An NIE and, in most cases, a Spanish bank account for social security direct debits

Step-by-step process

Register your economic activity with the Agencia Tributaria (modelo 036/037)
Register for self-employed Social Security contributions (RETA)
Set up invoicing that meets Spanish requirements (sequential numbering, correct VAT treatment)
File quarterly tax declarations and pay your monthly social security contribution

Required documents

NIE
Completed tax registration form (036/037)
Spanish bank account for social security direct debit

Common mistakes

Not budgeting for the monthly social security contribution, which is due regardless of income in the early months
Missing quarterly tax filing deadlines

Practical tips

New autónomos may qualify for a reduced initial social security rate (tarifa plana) — check current eligibility before registering
A gestor (a licensed administrative/tax professional) is commonly used to handle quarterly filings — it's a normal, affordable service in Spain, not a luxury
