revenues from business are extremely low, partly due to a 0% corporate income tax rate, which has been in place since 2008 [3]. But the situation is not much better from a business point of view. While the tax burden is practically zero, the administrative burden of the taxation system, which includes regulation of primary documents, tax accounting, reporting and other steps, is very high. Clearly, the business taxation system is highly inefficient and thus in desperate need for reform [4].
