Although energy prices have moderated from recent highs, Spain remains among the few European nations that still depend on windfall profit taxes to provide consumer relief. Unlike most European countries, Spain’s windfall taxes aren’t limited to fossil fuel or energy firms; they also extend to the banking sector. While both taxes are set to expire in late 2024, Spain’s government is considering making these taxes permanent, or at the minimum, maintaining the banking sector windfall tax.
Windfall profit taxes are typically designed to address extraordinary gains under exceptional conditions. However, Spain’s approach seems geared towards establishing these taxes as enduring fiscal tools unrelated to profitability. This strategy may negatively impact Spain’s economic growth. Instead, Spain should consider adopting more balanced tax policies that foster investment and bolster growth.
Historically, windfall taxes have been aimed at oil and energy firms during periods of escalating costs often tied to wars or crises. Spain first enacted a windfall tax in January 1939 under Francisco Franco at the close of the Civil War, imposing rates between 30% and 80% on individuals and companies regardless of their sector.
**Impact Of Windfall Tax on Green Energy Investments**
In the 21st century, Spain once again stands out as an early adopter of windfall taxes in Europe. In 2021, Spain introduced a temporary measure targeting excess revenues of energy companies benefiting from elevated energy and gas prices. Over time, several exclusions diminished its scope, leading to the exclusion of numerous energy providers.
By October 2022, the Council of the European Union established an EU-wide windfall profits taxA windfall profits tax is a one-time surtax levied on a company or industry during times of unexpected high profits. Inheritance taxes and taxes on lottery winnings are also types of windfall taxes on individual earnings.
or “solidarity contribution,” targeting fossil fuel enterprises (oil, gas, coal, refining sectors) to offset household energy costs transparently for all end consumers.
Under the regulation, member states could adopt a solidarity contribution or an equivalent national policy on surplus fossil fuel industry profits for 2022 and/or 2023. Spain opted for its version of a windfall tax.
In December 2022, Spain established a new windfall profits tax on major entities involved in crude oil and natural gas production, coal mining, and oil refining, albeit differing significantly from the EU mandate.
Primarily, Spain’s schema uses net turnover as the tax base instead of taxable profits. A 1.2% tax rate applies to domestic power utilities’ sales. This tax base isn’t aligned with taxing profitability, windfall or otherwise, and resembles excise taxesExcise taxes are levies on specific goods or activities, such as cigarettes, alcohol, and gasoline. They generally form a minor part of state, local, and sometimes federal tax revenues.

The tax targets companies with an annual turnover exceeding €1 billion in 2019 and is enforceable through fiscal years 2023 and 2024, diverging from the EU’s temporary 2023 windfall tax.
Spain’s tax design deviates in both duration and prescribed tax base from EU guidelines.
Following the EU-wide windfall tax ratification, Spain’s government committed to adjusting its windfall tax to EU standards. Yet, no changes were applied. Spain’s unwillingness to update its tax base prompted major electricity companies to challenge the tax’s “discriminatory” nature in a legal setting. Corporations declared their readiness to pay taxes on natural gas-related windfall profits but resisted taxing total domestic revenue.
A 2023 European Commission report suggested terminating such measures due to “noted investor uncertainty” generated by diverse member strategies. Though EU mandates stipulate windfall profits taxes as temporary, crisis-specific mechanisms, Spain declared during 2023 coalition talks intent to make permanent both its windfall taxes affecting energy and banking. Criticism from leading oil producers indicated this policy hindered investment, affecting strategic decisions about green hydrogen facilities.
On December 3rd, 2023, the government announced plans to reassess the energy windfall tax during 2024 budget discussions, but no budget was proposed. By the end of December 2023, the windfall taxes extended to 2024.
The persistence of these taxes directs capital away from carbon-intensive energy and diminishes funds for companies investing in renewable projects. Alongside investment reductions, windfall profits taxes can hasten the erosion of local oil and gas output, compromising energy security.
In 2024, Spain’s windfall tax on energy companies collected just €1.2 billion—similar to 2023’s intake. Meanwhile, the government announced €0.8 billion investment from EU funds in local businesses to develop green hydrogen. Subject to complex EU grant processes, Spanish firms could reclaim roughly a third of their paid windfall taxes from 2023 and 2024 to proceed with delayed green investments.
**Banking Sector Feeling the Windfall Tax Squeeze**
Spain’s windfall tax impacts the banking sector, applying to net interest income and net fees exceeding €800 million from 2019. A 4.8% rate applies for 2023 and 2024.
The banking tax, like the energy levy, doesn’t target profitability (windfall or otherwise).
Potential impacts include elevated loan interest rates and reduced capital supplies, limiting banks’ crisis management capabilities. The European Central Bank (ECB) critiqued Spain’s windfall tax on banks, warning it may constrain credit and weaken financial resilience in downturns.
Spanish banks hesitated to expand their exposure to national debt through loans and bonds.
Transforming this tax into a permanent fixture, as recently announced, could elevate interest rates, burden already struggling banks, distort banking competition, spark more litigation, and unjustly impact certain sectors due to a poorly structured tax base.
Instead of following arbitrary, provisional policies that weaken sectors and risk investment opportunities, policymakers should pursue long-term, growth-oriented tax reforms. Such policies can stimulate economic advancement, fortify financial institutions, and promote energy diversification by enhancing private investment through full expensingImmediate deduction of full costs on select investments promotes corporate spending, ultimately enhancing productivity, wages, and job numbers over time.
