The Polish government's yet-to-be published draft law on taxing hydrocarbons production may give the government as much as a 40% stake in hydrocarbon licenses, daily Dziennik Gazeta Prawna reports Tuesday citing an unnamed government official.

One option being considered is the creation of an entity, under the aegis of the Environment Ministry, which would hold stakes in licenses to produce oil and natural gas in
Poland .

The other option would discard the need for an entity, with private sector license-holders simply paying out an undecided percentage of their profit to the government, the daily says.

Poland wants to create a tax and regulatory framework for its embryonic shale gas sector, which it says it expects to start producing natural gas commercially in 2015 or 2016.
