As energy prices continue to rise, more European countries have been looking at windfall profit taxes—a one-time taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. levied on a company or industry when economic conditions result in large, unexpected profits—to fund relief measures for consumers. As early as March 8, the European Commission recommended in its REPowerEU communication that member states temporarily impose windfall taxes on all energy providers. The Commission suggested such measures be technologically neutral, not retroactive, and designed in a way that doesn’t affect wholesale electricity prices and long-term price trends.

According to statistics from the International Energy Agency, the Commission estimated these measures could yield up to €200 billion in 2022. The revenue could then be used to partially offset households’ high energy bills “in a non-selective and transparent measure supporting all final consumers.”

Countries like Romania and Spain already implemented a temporary mechanism in 2021 to cut excess revenues of energy companies that benefit from higher energy and gas wholesale prices.

Six months after the Commission’s recommendation and continued energy price increases, 15 European countries have either announced, proposed, or implemented windfall profit taxes.

What European Countries Are Doing about Windfall Profit Taxes and Windfall Tax policies in Europe Bloomberg Tax

Greece, Hungary, Italy, Romania, Spain, and the United Kingdom have implemented a windfall tax. The Czech Republic and Poland have published proposals to enact a windfall tax and Spain published a proposal to enact a second windfall tax because the first one was diluted by a series of exclusions that left many energy providers out of its scope. Belgium, Finland, Germany, Ireland, Netherlands, and Slovakia have either officially announced or shown intentions to implement a windfall tax. France is, for now, the only country that voted down a windfall tax proposal.

The proposed and implemented windfall taxes differ significantly in their tax rates (e.g., Greece’s is up to 90 percent) and their structures. Additionally, many of the proposed and enacted measures are not proper windfall profit taxes—they go beyond merely taxing windfall profits.

In most countries with windfall taxes, the tax baseThe tax base is the total amount of income, property, assets, consumption, transactions, or other economic activity subject to taxation by a tax authority. A narrow tax base is non-neutral and inefficient. A broad tax base reduces tax administration costs and allows more revenue to be raised at lower rates. is not designed in a way that exclusively captures the windfall profits generated by the spikes in energy and oil prices. In Romania and Spain, for instance, a tax on electricity sold over an arbitrarily determined price or on total sales is not a tax on profits at all—it resembles more of an excise taxAn excise tax is a tax imposed on a specific good or activity. Excise taxes are commonly levied on cigarettes, alcoholic beverages, soda, gasoline, insurance premiums, amusement activities, and betting, and typically make up a relatively small and volatile portion of state and local and, to a lesser extent, federal tax collections. . On the other hand, Italy’s windfall profit tax (the Incremental Added-Value) could be influenced by a variety of factors, including mergers and acquisitions, which are not linked to price changes.

In other countries, the tax base is calculated as the difference between the current profits and the profits generated over a baseline period. Nevertheless, these incremental profits are not necessarily excess or supernormal returnSupernormal returns are payoffs to investment greater than the typical market rate of return. They are often approximated as company profits that exceed 10 percent. This additional return on capital or labor is above breaking even on an investment relative to the amount of risk and time that investment required. s and a windfall tax could translate into double taxationDouble taxation is when taxes are paid twice on the same dollar of income, regardless of whether that’s corporate or individual income. of regular profits.

The flawed design of these windfall profit taxes has already created problems in countries that implemented them. While the constitutionality of Italy’s windfall tax is questioned, the country hardly collected €2 billion out of the €11 billion expected revenue. In Poland, as companies are already struggling with higher energy costs, business associations warned that this measure would “lead to an uncontrolled wave of bankruptcies that will hit the Polish economy.” In Spain, after the announcement of a possible EU-wide windfall tax, the country’s government vowed to adjust the two new windfall tax proposals, already heavily criticized by the targeted sectors, to the EU design.

It’s unlikely these implemented and proposed windfall taxes will achieve their goals of addressing high gas and energy prices and raising additional revenues. They would more likely raise prices, penalize domestic production, and punitively target certain industries without a sound tax base. Although an EU-wide windfall tax is not a good option, it does not have as many problems as the current proposed and implemented windfall profit taxes.

Implemented (In September 2021, Spain approved a temporal mechanism that is in force until December 31, 2022. The mechanism consists of a temporary reduction in the remuneration of electricity production activities to reduce windfall profits earned due to higher gas and carbon prices. The tax applies to facilities with a capacity of more than 10 MW and power plants not benefiting from public subsidies. The tax is payable if the gas price is higher than €20/MWh. The rate of the tax depends on the energy produced, the gas price, and the price of the energy produced by gas-powered plants. However, later on, a series of exclusions were approved and many energy providers were left outside the scope of the new mechanism. Proposed (In July 2022, the government submitted a new draft proposal with two new windfall taxes on the banking sector and energy companies. In September 2022, Spain vowed to adjust the new windfall tax if the EU proposal succeeds.)
United Kingdom (GB) 25% Oil and gas companies operating in the UK and the UK Continental Shelf On the same profits that are already subject to the UK’s oil and gas 40 percent headline tax, generating an effective tax rate of 65 percent. However, the new legislation also introduces an “investment allowance” which, together with other reliefs already available, enables taxpayers to obtain relief of up to 91.25 pence in the pound when they reinvest profits in the UK oil and gas sector. Implemented (Approved on July 11, 2022, applicable to profits generated on or after May 26, 2022, up to December 31, 2025.
