Overview

• Spain’s 2023 municipal IRPF data confirm Pozuelo de Alarcón at €88,011 and Boadilla del Monte at €70,869, widening the gap with Catalonia’s top entries.
• Five Madrid-area municipalities make the top 10, with four from Catalonia, and Aigües (Alicante) the only outlier, ranking eighth at €60,883.
• The national gross average declared income rose to €31,333 per taxpayer, and the Madrid region reached €40,801, surpassing €40,000 for the first time.
• At the lower end, Benamargosa (Málaga) recorded Spain’s lowest gross average at €13,831, reflecting wide geographic disparities across Andalucía and Extremadura.
• In the Valencian Community, the gap between the richest and poorest municipalities reached €43,022 (Aigües vs. Venta del Moro), and officials caution that small-population towns can see abrupt swings from inheritances or other extraordinary incomes; País Vasco and Navarra are not included in these figures.
