What is the standard Spanish corporate tax rate?

The standard Impuesto sobre Sociedades (IS) rate is 25%. This applies to most Spanish resident companies and permanent establishments of foreign companies.

When does the 23% SME rate apply?

Companies whose net turnover (cifra de negocios) in the prior tax year was below €1 million qualify for the reduced 23% rate. This threshold was introduced in 2023 as a permanent measure.

Who qualifies for the 15% startup rate?

Qualifying newly created companies under Ley 28/2022 pay 15% in the first tax period with a positive taxable base and the following three tax periods, provided they retain the required status. After that, the applicable standard or SME rate applies.

Is taxable profit the same as accounting profit?

No. Taxable profit is your accounting result adjusted for AEAT-specific additions and deductions — for example, non-deductible expenses, depreciation differences, and tax credits (deducciones). Enter the AEAT-adjusted figure for an accurate result.

Does this include surcharges or regional taxes?

No. The Basque Country and Navarre (Haciendas Forales) apply their own corporate tax regimes. This tool covers the common regime (régimen general) administered by AEAT, which applies to companies in all other autonomous communities.

Are quarterly instalment payments (pagos fraccionados) covered?

This tool calculates full-year IS liability. Quarterly instalments are typically 18% of the prior year's IS fee (Model 202, first method). Divide the annual result by roughly 5–6 for a rough instalment estimate, or consult your accountant for the precise method.
