Portugal to Impose Windfall Tax on Energy Companies Benefitting From Price Surge

Portugal's Plan for Windfall Tax on Energy Companies

Government Initiative and Parliamentary Approval

LISBON, May 5 (Reuters) - Portugal's government will request parliament's approval in the coming weeks to impose a windfall tax on energy companies profiting from an energy price surge amid the Iran war, Finance Minister Joaquim Miranda Sarmento said on Tuesday.

European Context and Coordination

Portugal, along with Germany, Italy, Spain and Austria, sent a letter to the European Commission in April, calling for such a tax at a European level, but Brussels left it up to individual countries to decide. 

Seeking Coordination With Other Countries

Miranda Sarmento said Portugal "would seek the highest possible level of coordination" with other countries and "learn from each other about potential measures that each may be preparing."

Policy Adjustments and Historical Reference

Recalibrating Previous Measures

"We will take the measures adopted in 2022, recalibrate them, improve them and, in the near term, present a proposal to parliament," Miranda Sarmento told reporters in Brussels, referring to the previous energy price shock after Russia's invasion of Ukraine.

Current Economic Context

Inflationary Pressures Compared to 2022

He said the current situation differed from 2022 as overall inflationary pressures are now far lower, with core inflation - excluding food and energy - running at around 2.2%.

Political Landscape and Approval Prospects

Although the centre-right government holds only a minority of seats in parliament, the proposal is expected to be approved with the backing of the Socialist Party, which introduced the mechanism in 2022.

Key Takeaways

  • Portugal will recalibrate and improve its 2022 windfall tax model and present a proposal to parliament shortly, with core inflation at around 2.2%–2.3% helping ease concerns about inflationary impact
  • Portugal and four other EU states (Germany, Italy, Spain, Austria) jointly urged the European Commission in early April to establish an EU‑wide windfall tax mechanism, though Brussels has left implementation to member states
  • This new wave of windfall taxing responds to energy price shocks triggered by the Iran war and aims to fund relief without raising public deficits
