Newsletter – proposed amendments to the petroleum tax regime

The Government announced on a press conference 31 August 2021 that they would propose amendments to the petroleum tax act. The Ministry of Finance then 3 September 2021 issued a public consultation paper where it is proposed that the rules on depreciation and tax-free income in the special tax for petroleum from 2022 should be replaced by immediate expense recognition of investments (cash flow tax – direct tax deduction). The Ministry of Finance emphasized that the proposed amendment is similar to amendment that entered into force for hydroelectric power with effect for investments made from 2021.
