Spanish IRPF & Seguridad Social explained

Two deductions shape a Spanish nómina (payslip): IRPF, the income tax withheld at source, and Seguridad Social, the social-security contribution. Together they explain the gap between your salario bruto and the salario netothat reaches your account. This guide explains both — and why your region matters.

Seguridad Social: the smaller, flatter deduction

The employee social-security contribution is a fixed percentage of your salary — around 6.35% in total, made up of common contingencies (~4.7%), unemployment (~1.55%) and a small training levy. It funds healthcare, pensions and unemployment benefit, with your employer paying a much larger share on top. There is a maximum contribution base(base máxima): earn above it and your Seguridad Social stops rising, so high earners see a smaller effective rate.

IRPF: the progressive income tax

IRPF is progressive, with rates climbing through brackets from roughly 19% to 47%+ at the top. Two features matter:

• The mínimo personal y familiar— a tax-free baseline that rises with dependants — means low earners pay little or no IRPF.
• IRPF is withheld at source by your employer as an estimate; your annual declaración de la renta reconciles it, producing a refund or a top-up.

Why your comunidad autónoma matters

IRPF is split into a state half and an autonomic half: each of Spain’s 17 autonomous communities sets its own rates and brackets for its portion. The result is real regional variation — the same salary nets differently in Madrid, Catalunya, Andalucía or the Comunitat Valenciana. (The Basque Country and Navarra go further still, running their own foral tax systems entirely.) A national-average calculator can therefore be off by a meaningful amount for your specific region.

See it for your salary

The Spain take-home pay calculatorapplies IRPF (state + autonomic) and Seguridad Social, with the main communities selectable, so you can see bruto → neto for any gross — for example a €35,000 salary. Because the withholding is an estimate and the autonomic half varies, treat the result as a close guide rather than your final annual figure — the declaración de la renta settles the exact number. Verify current rates before relying on them.
