How to use these calculators
Each calculator gives you an instant result and, below it, explains step by step how it was obtained, with a worked example and the official tables for the year. Legal parameters (income tax brackets, contribution rates, IPREM, severance days) are checked against official sources: the Spanish Tax Agency, Social Security, SEPE and the Official State Gazette (BOE).
Last reviewed: September 28, 2026. Results are estimates: your collective agreement or personal situation may change the final amount. The calculators cover Spain’s common tax territory; the Basque Country and Navarre have their own tax systems.
