Proceeds from social security tax in January 2016 amounted to 86% of the January 2015 figure, which indicates the correctness of the decision to reduce social security tax and the start of the economy's coming out of "shadows," Ukrainian Prime Minister Arseniy Yatseniuk has stated.

"The process of the economy's coming out of shadows has started, people are paid public and fair wages, not wages in envelopes," he said, speaking with the report in the parliament.

Yatseniuk explained that the transition from multiple rates of social security tax with an average level of about 41% of payroll to a single rate of 22% should have led to a two-time fall in revenues [to be more precise by 53.7%, and this is without taking into account the growth in wages, which in December 2015 stood at 21.9% from December 2014 that would have brought this arithmetic index to about 65.4%).

As reported, the International Monetary Fund (IMF) expressed concern that the effect of unshadowing from the reduction of social security tax will be low, therefore proposed the reduction of the rate to 28%.
