Portugal Joins Four EU Nations Demanding Windfall Tax on Energy Companies
Finance ministers from Portugal, Spain, Germany, Italy, and Austria have written to the European Commission demanding a bloc-wide levy on energy companies profiting from the Iran war.
Portugal's finance minister has co-signed a joint letter with four other European Union nations demanding that the European Commission impose a windfall profits tax on energy companies benefiting from soaring oil and gas prices driven by the war in Iran.
The letter, addressed to EU Climate Commissioner Wopke Hoekstra and first reported by Reuters on Saturday, was signed by the finance ministers of Portugal, Spain, Germany, Italy, and Austria. It calls on Brussels to "rapidly develop" a temporary solidarity levy at the EU level, modelled on a similar instrument introduced in 2022 during the energy crisis that followed Russia's invasion of Ukraine.
What the Letter Says
The five ministers argue that the Middle East conflict has created "market distortions" and imposed a "significant burden on the European economy and European citizens." They want energy companies that are profiting from the crisis to contribute to easing that burden.
"Those who profit from the consequences of the war must do their part to ease the burden on the public," the letter states, according to reports from LaPresse and the Associated Press. The ministers add that a European-level solution would send a signal of unity while helping fund temporary consumer aid and curb rising inflation "without placing a further strain on public finances."
The proposal explicitly preserves the right of individual member states to pursue their own measures. Spain's Economy Minister Carlos Cuerpo, who has been vocal about the initiative, confirmed the letter on the social media platform X.
Why It Matters for Portugal
Portugal is particularly exposed to the current energy price surge. The country imports nearly all of its oil and a significant share of its natural gas, meaning global price shocks translate almost directly into higher costs for consumers and businesses.
Diesel prices have already climbed sharply, with another eight-cent increase expected next week. The government has responded with a rolling ISP fuel tax discount — currently 4.58 cents per litre for petrol and 8.34 cents for diesel — and a 600 million euro credit line to help businesses absorb rising energy costs.
But these are national-level measures with limited fiscal room. A bloc-wide windfall levy would shift part of the cost to the companies profiting most from the crisis — primarily large oil and gas producers — and distribute the burden more evenly across the EU.
The 2022 Precedent
The letter explicitly references the 2022 EU solidarity contribution, a temporary windfall levy on fossil fuel companies that was introduced after the Russian invasion of Ukraine sent energy prices spiralling. That instrument was designed to capture "surplus profits" and channel them back to consumers and vulnerable households.
The current proposal follows the same logic: if energy companies are earning outsized profits because of a geopolitical conflict they did not cause, those profits should help cushion the blow for ordinary citizens. The key difference this time is that the five signatories want the Commission to act faster, reflecting a sense of urgency as inflation climbs and household energy bills rise across the continent.
What Happens Next
The letter does not carry binding force — it is a political signal. The European Commission would need to propose legislation, which would then require approval from EU member states. Given that the five signatories include three of the four largest eurozone economies, the political weight behind the request is significant.
Whether the Commission moves quickly enough to make a difference this spring remains to be seen. In the meantime, Portugal continues to manage the crisis through national measures, including the weekly fuel tax adjustment mechanism that takes effect every Monday and the broader energy resilience package announced last week.
For residents and expats watching their energy bills climb, the windfall tax push represents a potential — if still uncertain — route to relief that goes beyond what any single government can do alone.
