The EU’s renewed interest in windfall profit taxes comes as energy prices rise again amid Middle‑East tensions, prompting policymakers to revisit one‑time levies on firms that earn unexpectedly large profits from oil, gas, coal or related sectors.
EU‑wide framework and expected revenue
- The European Commission’s REPowerEU communication (March 2022) recommended a temporary, technologically neutral windfall tax on all energy providers, designed not to affect wholesale electricity prices or long‑term price trends.
- In October 2022 the Council of the EU agreed to an EU‑wide “solidarity contribution” on fossil‑fuel companies (oil, gas, coal, refining) together with a cap on market revenues for generators using infra‑marginal technologies (renewables, nuclear, lignite).
- The two measures were projected to raise ≈ €140 billion, of which €25 billion would come from the solidarity contribution on oil and gas firms.
- Collected revenues for fiscal years 2022‑2023 total €26.15 billion, slightly above the estimate, but they represent only 7 % of the €340 billion total cost of EU energy‑support programmes.
Participation of Member States
| Status (2025 report) | Countries |
|---|---|
| Applied solidarity contribution (or equivalent) | 16 of 27 EU members |
| Adopted an equivalent national measure | 8 members |
| No in‑scope companies (no tax) | Luxembourg, Latvia, Malta |
| Reported zero revenues despite applying the tax | Finland, Lithuania, Sweden |
| Never adopted the regulation | Cyprus |
| Applied tax to all sectors (no separate revenue data) | Croatia |
| No revenue data available | Remaining 8 members (including the three with zero‑revenue reports) |
Thus, 19 of the 27 EU states have usable revenue data for the solidarity contribution or a comparable national scheme.
Extensions beyond the energy sector
- As oil, gas and coal profits fell, several countries broadened the tax base to include banking and financial services.
- Current jurisdictions with such extensions: Hungary, Romania, Slovakia, and Spain.
Tax rates across Europe
Windfall profit taxes in Europe vary widely:
- Romania – 0.5 %
- Poland – proposed up to 60 %
- Other EU countries impose rates between these extremes (specific percentages not detailed in the source).
United Kingdom example
- Although no longer an EU member, the UK introduced a windfall profit tax in 2022 that applies exclusively to companies engaged in oil and gas extraction.
Key take‑aways
- The EU’s solidarity contribution has generated modest revenue relative to the overall cost of energy assistance.
- Data gaps remain for several Member States, limiting full assessment of the tax’s fiscal impact.
- Scope extensions to the financial sector indicate a shift in policy focus as energy‑sector profits normalize.
- Wide variation in tax rates—from under 1 % to a proposed 60 %—reflects divergent national approaches to capturing windfall gains.
