Tax contribution
The Iberdrola Group’s total tax contribution worldwide will exceed €10.4 billion in 2025
The tax transparency report, published for the eighth consecutive year, shows an increase in the Iberdrola Group’s direct tax contribution worldwide, reaching over €10.4 billion during the past financial year, which equates to a payment of more than €1 million per hour.
Spain was the country that contributed the most in 2025, with a contribution of €4.675 billion, 8% more than in 2024. It was followed by Brazil (€2.328 billion), the United States (€1.384 billion), the United Kingdom (€1.061 billion), Mexico (€645 million) and the rest of the countries (€317 million).

The figure for taxes accounted for 44% of the company’s profit, reducing daily profit by €14 million. Within this figure, electricity taxes represent a very significant proportion of the contribution, particularly in Spain, which faces the Group’s highest tax burden, despite the company’s clear commitment to energy self-sufficiency and sustainability.
In 2025, Iberdrola paid €1,241 million in electricity taxes in Spain, compared with €328 million across the other 31 countries in which it operates.
Sustainable tax responsibility: 2021–2025
Thus, over the last five years, the Group’s contribution to the public purse amounted to €45 billion, a figure similar to the dividends paid by the company to its shareholders over the last 25 years.
In Spain, Iberdrola has paid more than €19 billion in the period 2021–2025, representing over 40% of the Group’s tax contribution during that period.
Committed to fiscal responsibility
Through the preparation of the Transparency Report 2025: our commitment to society [PDF], Iberdrola wishes to highlight the Group's significant tax contribution throughout the world - "essential for sustaining public expenditure", in the words of the company's chairman, Ignacio Galán-, especially in Spain.
"The electrification process requires stable frameworks and sound energy policies. This requires tackling a reform of electricity taxation, particularly in Europe, to make it more balanced and remove barriers to electrification, competitiveness and long-term investment, because the European Union urgently needs investment to enable decisive progress towards greater energy self-sufficiency based on indigenous resources, modern infrastructure and a robust and resilient electricity system."
Ignacio Galán, Executive Chairman of the Iberdrola Group
A key component of the Iberdrola Group's social dividend is our contribution to the public coffers, in accordance with the law and in line with the expectations of the various countries in which we operate and society in general. The contribution of large companies to the sustainability of tax systems is essential to ensure the best possible provision of essential goods and services, and at Iberdrola we are fully aware of the importance of fulfilling this responsibility.
With the publication of the Fiscal Transparency Report, we have made substantial progress in our transparency practices, making public all fiscal information that may be relevant for our stakeholders: shareholders, suppliers and people to whom we supply energy, public administrations and regulatory bodies, our staff, the media and society in general.
The Fiscal Transparency Report includes all the information contained in the Iberdrola Group’s Country-by-Country Tax Report of the Iberdrola Group 2025.
