BeHidden, black, untaxed or shadow economy, all terms mean the same thing, but even though we have several words about the phenomenon, many people do not know what it is, its extent and there are no exact values about how the black economy is developing in Hungary. A black economy is, in short, the part of the economy after which no tax has been paid, so for example, the activity that takes place or the employment takes place in black is unofficial. We talk a lot about it, and the government is also making more and more efforts to whiten the economy. As a result of a number of measures taken, there are rumors that the shadow economy has been reduced. What exactly is a hidden economy? To what extent is the tax-free economy in Hungary? Can the existence of the black economy be completely abolished, can the economy be completely bleached? I am looking for answers to these questions within the framework of this scientific article. What is the impact of the COVID-19 epidemic on the hidden economy and what responses might the government have?
