States often favor severance taxes over alternative sources of government revenue because much of the severance tax burden is transferred out of the state. ‘Exporting’ the tax burden is achieved, for example, if a relatively small portion of the oil pumped from an oil-abundant state is used in that state or if out-of-state companies own oil production. (The University of Utah)

A severance tax can provide local jurisdictions with additional revenues to finance economic development, yet the imposition of a tax may create coal industry employment losses. (ScientificCommons)

The change in severance tax cannot, of course, take place in isolation. It should be carried out in conjunction with the other elements of the tax system, i.e. export duties and excise taxes. (OIL OF RUSSIA)
