This article has been edited by Mansi Bathija and written by Ayushi Yadav, a fourth-year law student from Banasthali Vidhyapith, Rajasthan. In this article, she has discussed the basics of the Indian income tax act of 1961.

Introduction to Income Tax

Tax is the mandatory financial charge demand by the government on pay, product, administrations, exercises or exchange. Taxes are the fundamental modes of income for the government, which are used for the welfare of the general population of the nation through government strategies, arrangements, and practices. 

There are references for taxes in ancient writings like Manusmurti and Kautilya Arthashastra. It was initiated in India in 1860 for the first time to defeat the financial crisis of 1857. Accordingly, it is the income tax Act 1961 which is at present operative in India

Constitutional Provisions of Taxes in India

The basis of every legislation in India is rooted in the constitution. As per article 265 of the constitution, no tax must be levied or collected except by the authority of law. There are various other provisions under the constitution that distribute the power.

Need for Income Tax in India

Income tax is a tax on the income of an individual or an entity. Income tax is the main source of income for the government to carry out its functions. The jobs of government are not just restricted to defense, law, and order, etc., but it also has to undertake activities like welfare and development under sectors of health, education, rural development, etc. the government also has to pay for its own administration. All of these activities need huge public finance which is raised by the collection of taxes.

Purpose of Taxation

  1. The money spent on the development of roads, schools, and hospitals, market regulations or legal systems, etc. is raised by the revenue generated by the collection of taxes
  2. Redistribution of resources by the richer section to the poorer section of the society.
  3. Taxes are levied on certain products to eliminate externalities such as the taxes on tobacco to discourage smoking

Taxes are broadly divided into two categories- Direct and Indirect taxes.

Income tax is a direct tax imposed on an individual. Estate and wealth tax were also direct taxes, however, these are abolished now

Indirect taxes that were imposed in India are customs duty, central excise duty, service tax, sales tax, and value-added tax.

As of now GST has been implemented and has made all the other indirect taxes obsolete.

For the previous year 2015-16, he is a resident for he has stayed in India for more than 182 days in the year ending 31st March 2016

What is Payroll Tax

Payroll taxes are Medicare and social security taxes, employers withhold half of these taxes from employee’s wages. Medicare taxes are a contribution to medical benefits for the person above the age of 65. Social security taxes are for the benefits of the retired person or disabled person or for their dependents. These two taxes are called as FICA tax, i.e., Federal Insurance Contribution Act Tax, which is defined by Internal Revenue Service. These taxes are paid to the Federal or State authority.  

If a person is self-employed then he doesn’t need to pay FICA tax, but a Self-employed Tax needs to be pay by him.
