What is Income tax in India?

The major source of revenue of any country is through a collection of taxes on income and other transactions. Income tax is a direct tax that is collected from the person who is liable to pay, the person who makes the payment to the government, and the person who is liable to pay taxes are the same. For efficient tax management, in some cases, the taxes will be collected by the person making the payment to the person in case of certain transactions through tax deduction and tax collection at the source (TDS/TCS). Even though TDS/ TCS is remitted by the person making the payment, it is not the final liability.

Power to collect Income tax and tax administration is given to the central government through “entry no 82 list I, seventh schedule article 246 of the constitution of India. Any changes to the act or amendments can be done only with the approval of the parliament. Income tax rules facilitate the smooth implementation of the act, and it cannot override the provisions of the Income Tax Act.
