Black market types
The black market can be classified as a black market for legal products or a black market for non-legal products.
Black market for legal products
In this case, what is outside the law is the way in which the activity is carried out. In this type of black market, the income received from an activity that is legal is not declared. Nor are the impuestos corresponding to said activity. In this type, for example, payment to a professional would be framed without the latter issuing an invoice, saving the payment of taxes.
Black market for illegal products
In this type of black market, the activity carried out is not legal. It is about those cases in which illegal products are sold and the black market is not limited to mere tax evasion. This type of black market is common in the sale of drugs, weapons or even organs and people.
