Calculations use 2026 Beckham Law and IRPF rates. The standard-regime figures follow the Agencia Tributaria's 2026 withholding algorithm: Social Security, €2,000 of expenses and the work-income reduction come off the base, and the €5,550 personal allowance applies (single filer, no dependants). The annual return then settles your region's own scale, so final liability varies by autonomous community. Beckham Law eligibility depends on not having been a Spanish tax resident in the prior 5 years and filing within 6 months of Social Security registration. Social Security is applied under standard Spanish rules in both regimes; some Beckham Law beneficiaries may instead remain covered by a home-country scheme under EU coordination or a totalization agreement. For precise advice consult a Spanish tax adviser or the Agencia Tributaria.
Permanent median
42.000 €
30.833 € take-home
Contract median
327 €/day
≈ 71.940 € gross a year
At a median 327 €/day, contract work grosses about 71.940 € a year over 220 billable days, 71% more than the 42.000 € permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Full-Stack Engineer (React / Next.js / TypeScript) contract rates and contractor take-home →
