This paper is aimed to analyze the taxation influence upon the company’s activity. Fiscal management is integrated into the company management and must therefore be defined in terms of general policy objectives of the company. The efficiency of fiscal policy is an essential element of fiscal management. This can be achieved directly (through the tax law that includes measures of fiscal incitement) or indirectly (when the tax system offers a number of tax deductions for expenses, the possibility to cover losses from previous financial periods, the limitation of deductible expenses according to earnings before taxes etc.). The two forms of efficiency of fiscal policy are placed in the calculation of relations between fiscal management, strategic planning, tax risk and accounting. Fiscal policy should aim at the company’s research and to achieve optimal cost of taxation. This paper analyses the methods that the companies dispose of in order to reduce this cost.
