Understanding the Portugal corporate income tax rate is essential for companies planning to establish operations in the country or structuring cross-border investments involving Portuguese entities. Portugal offers a relatively competitive corporate tax framework within the European Union, particularly in the Autonomous Region of Madeira, and also provides specific regimes to prevent double taxation of foreign operations.
This guide explains the Portugal corporate income tax rate in 2026, the taxation of permanent establishments, and the optional regime available for Portuguese companies operating foreign branches.
Portugal Corporate Income Tax Rate in 2026
The Portugal corporate income tax rate (Imposto sobre o Rendimento das Pessoas Coletivas – IRC) depends on the company’s location and, in certain cases, its size.
For companies resident in mainland Portugal, the standard corporate income tax rate is 19%, applied to the company’s global taxable income. This rate also applies to permanent establishments in Portugal of foreign entities, meaning that international companies operating through a branch in Portugal are generally taxed under the same framework as resident companies.
Corporate Income Tax Rates in Madeira
The Autonomous Regions of Madeira benefit from lower corporate tax rates designed to support regional economic development.
In Madeira, the standard Portuguese corporate income tax rate is reduced to 13%. This regional rate applies to:
Companies tax residents in the Autonomous Region; and
Permanent establishments of foreign entities registered and operating there.
These regional rates are one of the reasons Madeira has become an important jurisdiction for international businesses establishing operations within the European Union.
Reduced Corporate Tax Rates for SMEs
Portugal also provides preferential corporate tax rates for small and medium-sized enterprises (SMEs) and Small Mid-Cap companies.
In mainland Portugal, qualifying companies benefit from a reduced Portugal corporate income tax rate of 15% on the first €50,000 of taxable income. Any income exceeding this threshold is taxed at the standard rate of 19%.
In the Autonomous Region of Madeira, the preferential rate is lower. SMEs and Small Mid-Cap companies may apply a 10.5% corporate income tax rate on the first €50,000 of taxable income, with the standard regional rate of 13% applying to the remaining profits.
These incentives are designed to support business development and improve competitiveness for smaller companies.
Special Incentives in Madeira – the MIBC
To encourage economic development in the Autonomous Region of Madeira, the region offers an additional incentive for companies operating within the institutional framework of the Madeira International Business Centre (MIBC).
Qualifying companies that carry out their activities and maintain effective management may benefit from a 5% corporate income tax rate on all profits derived from activities with non-Portuguese entities.
This measure forms part of a broader policy aimed at promoting regional cohesion and supporting economic activity outside major urban centres.
Additional Reduced Rates in Certain Regional Territories
Under specific conditions, SMEs and Small Mid-Cap companies operating in the Madeira beneficiary territory may benefit from an even lower rate.
In these cases, the Portugal corporate income tax rate may be reduced to 8.75% on the first €50,000 of taxable income. In contrast, the applicable regional standard rate applies to profits exceeding that threshold.
Taxation of Permanent Establishments in Portugal
Foreign companies operating in Portugal through a permanent establishment (PE) are subject to corporate taxation on the income attributable to that establishment.
Portugal applies the same corporate income tax rules to permanent establishments as to resident companies, meaning that profits generated through a Portuguese branch are taxed under the standard Portuguese corporate income tax rate applicable in the region where the PE is located.
By contrast, non-resident companies without a permanent establishment in Portugal are generally taxed on Portuguese-source income through withholding taxes, depending on the nature of the income and any applicable double taxation treaty.
Optional Exemption for Foreign Permanent Establishments
Portugal provides an optional regime that allows companies resident in Portugal to exclude profits and losses arising from a foreign permanent establishment from Portuguese taxation.
This regime can significantly reduce the risk of international double taxation but is subject to several conditions.
The exemption applies only if the foreign permanent establishment:
Is subject to and not exempt from a tax listed in Article 2 of the EU Parent-Subsidiary Directive (Directive 2011/96/EU) or a tax similar to Portuguese corporate income tax;
Is located in a jurisdiction where the legal tax rate is at least 60% of the Portuguese standard CIT rate, effectively meaning a minimum rate of 12%;
Is not located in a Portuguese black-listed jurisdiction; and
Is subject to an effective tax rate of at least 50% of the tax that would be due under Portuguese corporate tax rules, except where specific statutory conditions allow otherwise.
Additionally, the regime does not apply to profits allocated to the foreign permanent establishment up to the amount of losses previously attributed to that establishment that the Portuguese company deducted during the previous twelve tax years.
The election for this regime must apply to all permanent establishments located in the same jurisdiction, and once chosen, it must remain in effect for a minimum of 3 years.
Entities Without Commercial Activity
Entities whose main activity is not commercial, industrial, or agricultural are taxed at a different rate.
In these cases, the Portugal corporate income tax rate is 19% in mainland Portugal and 13.3% in the Autonomous Regions of Madeira, applied to the global amount of taxable income.
Final Thoughts on the Portugal Corporate Income Tax Rate
The Portugal corporate income tax rate is relatively competitive within the European Union, particularly when regional rates and SME incentives are factored in. Businesses operating in Madeira benefit from significantly lower tax rates, while international companies can also rely on mechanisms such as the foreign permanent establishment exemption regime to reduce double taxation on overseas activities.
For companies considering expansion into Portugal, understanding how the Portugal corporate income tax rate interacts with regional incentives, permanent establishment rules, and international tax provisions is critical for designing an efficient corporate structure.
