On 30 December 2022, Bulgaria published the Law on the implementation of the provisions of the State Budget, the Public Insurance Budget, and the National Health Insurance Fund Budget for 2022, which includes various measures that will apply until the adoption of the budget for 2023. One of the key tax measures is the introduction of a windfall tax on electric power producers with electric power production facilities with an installed capacity of more than 1 MWh in accordance with Council Regulation (EU) 2022/1854 on an emergency intervention to address high energy prices. The tax is levied at a rate of 90% on the difference between the market revenue per MWh and the prescribed revenue ceiling for the relevant type of producer. The prescribed revenue ceilings will be determined by an act of the Council of Ministers. The tax applies from 1 December 2022 to 30 June 2023.
