To the question of the development of criminal mechanisms of “shadow collection” and the strong influence of the construction sector of the economy on them

The article illustrates examples of successful interaction of various government agencies in the fight against illegal cash withdrawal and the functioning of one-day firms. At the same time, the author draws attention to the transformation of the mechanisms of criminal activity in the credit and financial sphere. As an indirect criterion, an assessment of the volume of the shadow economy is proposed, which, despite the successes achieved, has practically not decreased. 
In this regard, the author actualized the problems of improving the mechanisms of turnover of “black cash”. Their transformation from the classic “cashing out” of funds using credit institutions to “shadow collection” is clearly illustrated. Its content is disclosed, which is the concealment by organizations engaged in the sale of consumer goods of their available cash from official collection to credit organizations for their subsequent transfer to intruders. 
The causal relationships that cause such a high interest of individual sectors of the economy in the use of black cash are formulated.
