Spain has a corporate income tax regime with a standard rate of 25%, as specified in the Corporate Income Tax Law (Ley 27/2014, de 27 de noviembre, del Impuesto sobre Sociedades; “Spanish CIT Act”), which applies to most corporate taxpayers, while also providing for reduced and specific rates for certain entities, a minimum effective tax rule, and distinct regional tax regimes in the Basque Country and Navarre.
The following specific rates are currently in force:
Spain has introduced a minimum effective corporate income tax (CIT) rate rule, applicable to tax periods beginning on or after 1 January 2022. Under this rule, an entity’s net tax liability-calculated after applying deductions and allowances, but before applying certain tax credits-may not fall below the following floors:
Basque Country and Navarre Tax Autonomy
The standard corporate income tax system does not cover the Territorios Forales, which include the Basque Country’s provinces of Álava, Guipúzcoa, and Vizcaya, as well as Navarre’s Foral Community. These regions have their own authority to set their own corporate tax rules.
Spain transposed the EU Minimum Tax Directive (Council Directive (EU) 2022/2523, implementing the OECD Pillar Two Global Anti-Base Erosion (GloBE) rules) through Law 7/2024, of 20 December 2024, which established the Impuesto Complementario (complementary tax).
Tax Residency Criteria and Worldwide Income
A business qualifies as tax-resident in Spain if it satisfies any of the following criteria:
Taxable income. Resident entities are subject to CIT on their worldwide income.

These adjustments cover items like permanent differences, timing adjustments, and specific allowances or restrictions.
Participation Exemption and Foreign Tax Credits
Spain offers a participation exemption for dividends and capital gains from qualifying investments. While capital gains are included in the general taxable base and taxed at the standard rate, dividends and gains from selling qualifying shares receive a 95% exemption—meaning only 5% remains taxable, resulting in an effective tax rate of up to 1.25% at the 25% corporate tax level, provided certain requirements are fulfilled.
Practical note: the reduction from 100% to 95% exemption (introduced in 2021) is subject to significant litigation and legislative debate. The 5% non-exempt portion is intended to represent a proxy for the costs related to managing the shareholding.
Where the subsidiary is resident in a jurisdiction with which Spain does not have a double tax treaty (DTT) or exchange of information agreement, or if the conditions for the participation exemption are not met, a tax credit for foreign taxes paid is available as an alternative mechanism to avoid double taxation.
Income attributable to a permanent establishment (PE) of a Spanish resident entity abroad may benefit from an exemption (rather than a credit) under Article 22 of the Spanish CIT Act, subject to equivalent conditions (the PE must be located in a jurisdiction with a CIT analogue of at least 10%). Losses from exempt foreign PEs are not deductible.
Non-resident companies face taxation under the Non-Resident Income Tax (NRIT), also called Impuesto sobre la Renta de No Residentes (IRNR). This is regulated by Royal Legislative Decree 5/2004.
VAT, IGIC, and IPSI Taxes
Spain collects multiple indirect taxes, with the most important being value-added tax (VAT), transfer taxes, and stamp duties, along with various industry-specific levies.

It applies VAT under Ley 37/1992, de 28 de diciembre, del Impuesto sobre el Valor Añadido, which transposes the EU VAT Directive (2006/112/EC). The rates applicable in mainland Spain and the Balearic Islands are:
Specific Tax Rates and Withholding Obligations
The Canary Islands, outside the EU VAT area, apply the Impuesto General Indirecto Canario (IGIC) at a general rate of 7%. Ceuta and Melilla instead apply the Impuesto sobre la Producción, los Servicios y la Importación (IPSI). Transfer tax and stamp duty (ITP/AJD) operate as a regional tax with three modalities, each governed by the respective autonomous community’s legislation.
Withholding obligations under the CIT Act and Personal Income Tax Law apply to specific income types paid to Spanish tax residents, with rates contingent on the income nature, recipient residency, and applicable treaty relief. Non-resident withholding taxes under the NRIT regime also follow domestic rates, reducible under double tax treaties or EU Directives. The applicable rates and conditions vary based on the payment’s character and the recipient’s jurisdictional status.
Anti-Avoidance Measures and Tax Controversy Procedures
It employs general anti-avoidance rules (GAAR) primarily through Article 15 of the General Tax Law, which addresses conflicts in tax norm application, replacing the prior abuse-of-law provision. Article 16 targets simulación, where transactions lack economic substance, allowing authorities to recharacterize acts based on their underlying reality, with penalties applying.
In addition to the general provisions, Spanish tax law contains a full body of SAARs, including: Based on STA audit activity and recent case law from the Tribunal Supremo (Supreme Court) and the Audiencia Nacional (National High Court), the most frequently disputed issues are: Tax controversy resolution follows a structured process governed by the General Tax Law, with a standard four-year limitation period, extendable for criminal fraud cases.
It lacks a general domestic mediation system for tax disputes but utilizes mutual agreement procedures under double tax treaties. Ongoing policy discussions explore broader alternative dispute resolution mechanisms, though no reforms have been enacted as of the guide’s publication.
