Corporate Income Tax in Spain — Rates, Deductions and the New Entity Regime
The Impuesto sobre Sociedades (Corporate Income Tax or CIT), governed by Law 27/2014, taxes the worldwide income of entities resident in Spain at the standard rate of 25%. This rate falls below the OECD average (23.5% in 2025) and is competitive against major European economies: Germany (29.8% effective including Gewerbesteuer), France (25.83% including contribution sociale) and Italy (27.9% including IRAP).
Newly created entities that generate a positive tax base benefit from a reduced rate of 15% in the first profitable fiscal year and the following year (Article 29.1 LIS). This incentive is particularly relevant for subsidiaries of multinationals starting operations in Spain, as it allows reinvestment of a larger proportion of initial profits into local growth.
Spain offers a broad catalogue of deductions and tax incentives relevant to international companies. The R&D tax credit (Articles 35-36 LIS) provides deductions of between 25% and 42% of research and development expenditure, and 12% for technological innovation. The Patent Box (Article 23 LIS) allows a 60% reduction in the tax base of income from the transfer of patents and intangible assets. Additionally, employment creation deductions and deductions for investments in film production complement the incentive framework.
For the calculation of the tax base, the starting point is the accounting result under the Spanish General Accounting Plan (Plan General de Contabilidad, RD 1514/2007), with the extra-accounting adjustments provided for in the LIS. Differences between Spanish accounting standards (PGC, IFRS-adapted) and the group’s standards (IFRS, US GAAP, local GAAP) require a reconciliation process that Euroaccounts manages as part of its tax compliance service.
