Shestakova E. V. — The taxation and economy in the industry

The industrial economy in mainly depends on the taxation. High rates of taxes are capable to force the companies looking for the ways of tax burden reduction, leaving from taxes, offshore zones searching. The preferential modes accepted for example at export of oil, are capable to support certain branches of economy, at the same time, these measures of support of one branches allow to speak about priority and not priority branches of economy. In this paper the authors try to consider aspects of the taxation, and also possibility of tax planning for the companies.
