Spain vs California: take-home pay comparison

Spain's IRPF + Seguridad Social against California federal + state + FICA — common remote-tech move.

A growing comparison for remote-tech professionals splitting time between Spain and the US west coast. Spain's IRPF tops out at 47% (state + region combined) + Seguridad Social at 6.35% capped at €56,646 brut. California's combined federal + state + FICA tops out at ~52% above $626k of income — higher than Spain at the top but much lower at the bottom (Spain hits 30% IRPF at €35,200, California reaches 22% federal at $48,475 + 4.0% CA + 7.65% FICA = ~34% effective).

At mid incomes (€60–80k / $80–110k), California retains substantially more net than Spain due to Spain's much heavier social-insurance base. The crossover happens around the top tramo of each side. Cost of living + the Beckham law special regime (Spain) are not modeled — both shift the picture materially.
