The Federal Tax Service revealed that TNK-BP had arrears for 2001 amounting to 26 billion rubles. Experts are wondering what exactly prompted domestic tax collectors to take this step. Some see the reason in the strict collection plan that the Federal Tax Service received. Others are due to the desire of the authorities to show that gigantic taxes are imposed not only on YUKOS. One way or another, tax officials have already gone against the president, who just in Hannover promised foreign investors not to change the rules retroactively.
