The Spanish income tax calculator (IRPF) computes your net salary after state and regional tax rates, plus social security contributions. Spain's IRPF is split between a national rate and a rate set by each autonomous community, so where you live directly affects how much tax you pay. This tool uses 2025 IRPF brackets and the standard 6.35% employee social security rate.

How to Use the Spanish IRPF Income Tax Calculator
Spain's IRPF (Impuesto sobre la Renta de las Personas Físicas) is a joint state and regional tax on earned income. Unlike most European countries where a single national rate applies, your Spanish income tax depends on both the central government rate and the rate set by the autonomous community where you are resident. This calculator uses 2025 state IRPF brackets and the most current regional rates for each community.
Step 1: Enter Your Gross Annual Salary
Enter your gross salary (salario bruto) — the amount before any deductions. In Spain, payslips show the base bruta with separate lines for social security (cotizaciones) and IRPF withholding. Social security contributions of 6.35% are deducted first, and the resulting reduced income forms the basis for applying the IRPF personal minimum reductions.
Step 2: Select Your Autonomous Community
Your tax residence determines which regional IRPF rates apply. Madrid consistently applies the lowest regional rates among major communities — a meaningful advantage for high earners. Catalonia has some of the highest regional rates. The Basque Country and Navarra have their own separate tax systems (concierto and convenio económico) with different structures from the rest of Spain, approximated here.
Step 3: Select Filing Status and Dependents
Single filers and married filers have different thresholds and personal minimums. If you have dependent children, each child adds to your mínimo personal y familiar, which is applied as a tax credit against your final IRPF liability. This reduces the tax effectively paid, particularly for families with multiple children.
Step 4: Review Your IRPF and Net Salary
The results show your state IRPF and regional IRPF separately, along with your social security contribution (6.35%). The effective rate is the total deductions (IRPF + SS) as a percentage of gross salary. For official Spanish tax purposes, your employer calculates and withholds IRPF monthly based on your annual estimated liability. You file your annual declaración de la renta with the Agencia Tributaria (AEAT) each spring.
Understanding Spanish Social Security Contributions
Employee social security contributions (cotizaciones sociales) total 6.35% of gross salary: 4.70% for common contingencies (pensión), 1.55% for unemployment, and 0.10% for professional training and FOGASA (wage guarantee fund). Contributions are calculated up to the base máxima de cotización, so very high earners pay a flat amount above the ceiling. This calculator caps contributions at the 2025 ceiling.

What is IRPF and how does it work in Spain?
IRPF (Impuesto sobre la Renta de las Personas Físicas) is Spain's personal income tax. It combines a state-level rate and a regional rate set by each autonomous community. Your total IRPF rate is the sum of both. The tax is progressive, with higher incomes paying higher rates.
Which autonomous community should I select?
Select the autonomous community where you are a tax resident — typically where you have lived for more than 183 days in the tax year. This matters because regional rates differ significantly. Madrid has some of the lowest regional rates in Spain, while Catalonia has higher ones.
What is the social security contribution rate in Spain?
Employees pay 6.35% of gross salary in social security contributions (cotizaciones sociales): 4.70% for general contingencies (pensión), 1.55% for unemployment, and 0.10% for professional training. These are capped at the base de cotización máxima.
Which 2025 IRPF state tax brackets does this calculator use?
The 2025 state IRPF bands are: 9.5% up to €12,450, 12% from €12,450 to €20,200, 15% from €20,200 to €35,200, 18.5% from €35,200 to €60,000, 22.5% from €60,000 to €300,000, and 24.5% above €300,000. Regional rates are added on top of these.
Does this include the mínimo personal deduction?
Yes. The calculator applies the standard personal minimum (mínimo personal y familiar) of €5,550, which converts to a tax credit. This is the basic tax-free equivalent for all Spanish residents and reduces your final IRPF liability.
Should I use this to file my Spanish tax return?
No. This is an estimation tool for planning purposes only. Spanish tax returns (declaración de la renta) must be filed with the Agencia Tributaria (AEAT). Always consult a gestor or asesor fiscal for official advice tailored to your situation.
