On 1 November 2022, the Government of Bulgaria submitted a draft bill to the Parliament regarding a temporary solidarity contribution of 33% on oil, gas and coal companies in line with the Council Regulation (EU) 2022/1854 of 6 October 2022 on an emergency intervention to address high energy prices.

The temporary solidarity contribution will be applicable to taxable profits for 2022 and 2023. The excess profits will be calculated as the taxable profits that exceed 20% of the average taxable profits for the tax periods 2018 to 2021. The deadline for the payment of the temporary solidarity contribution will be 30 June of the following year (similar to the annual corporate tax payment).
