Poland has published the Law of 11 September 2019 on repealing the Hydrocarbon Tax Law and certain other amendments. The hydrocarbon tax was approved in August 2014 and was to apply from 1 January 2020 to profits from the exploration of shale gas and oil at varying rates based on the ratio of the taxpayer's income to qualified expenses. However, because there have been no real developments with respect to shale gas and oil in Poland, it was decided to repeal the tax before it was to take effect.
