Calculations use 2026 Beckham Law and IRPF rates. The standard-regime figures use the combined state + Madrid autonomous-community scale as a representative case; actual standard-regime take-home varies by which autonomous community you live in (Catalonia and Valencia, for example, have higher top marginal rates than Madrid). 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.
