Demonetization is the act of removing currency as legal tender. The current form of money is stripped from circulation and dismissed in the case of demonetization. New forms of notes and coins are replaced by the old ones. Nations often fully introduce a new currency by replacing the old currency. The most crucial thing about demonetization is that notes and coins of a certain denomination are banned by the central government. There are certain merits and demerits of demonetization. When a new policy is introduced by the government, it has to face several challenges and obstacles. Demonetization is not an exceptional one. The dealing of black money stops abruptly because of demonetization. Government pushes the future of the corrupt people in stringent darkness by implementing demonetization across the nation. Liability of the government is reduced by the introduction of demonetization. The risk and liability of liquid currency is reduced too. It is quite convenient to handle soft money in place of hard currency. Demonetization also reduces the liability notes of the government. One of the huge impact of demonetization is that in certain cases, it leads to tax avoidance. The deposited money will be tracked by the Income Tax authorities. Hence, people who are known for their tax avoidance will become hesitant to do so. This will lead to fulfilling the government exchequer in a proper way. The transaction of loan will also be under review. Flow of taxes will increase. This will lead to the implementation of different welfare measures taken by the government. Demonetization is one of the historical steps taken by the Government of India so far. It was no less than a financial revolution to curb corruption. However, it is a continuous process which will be reviewed by the government from time to time. Although there are certain challenges faced by the policy, the primary objectives of demonetization have been achieved. The loopholes of the policy can be repaired but the national interest of demonetization should be acclaimed. One of the major challenges faced by the introduction of demonetization is the connectivity of the internet.
