Problems of informal sectors of economy to the government

Answer 1

The informal sector, informal economy, or grey economy[1][2] is the part of an economy that is neither taxed nor monitored by any form of government. Unlike the formal economy, activities of the informal economy are not included in a country's gross national product (GNP) or gross domestic product(GDP).[3] The informal sector can be described as a grey market in labour.

Other concepts that can be characterized as informal sector can include the black market(shadow economy, underground economy), agorism, and System D. Associated idioms include "under the table", "off the books", and "working for cash".
