Income Tax in India was introduced by Sir James Wilson on 24 July 1860. It was a tax selectively imposed on the rich, royalty and Britishers, and hence was not liked by the powerful. In its first year, the exchequer collected a princely sum of Rs.30 lakh. The Act lapsed in 1865 and was re-introduced in a different form in 1867. Tax rates were based on a rough-and-ready assessment.

In the modern times, income tax is an annual tax on income. The Indian IncomeTax Act - External website that opens in a new window (Section 4) provides that in respect of the total income of the previous year of every person, income tax shall be charged for the corresponding assessment year at the rates laid down by the Finance Act for that assessment year.

Who is to Pay Income Tax?
The word income has a very broad and inclusive meaning. In case of a salaried person, all that is received from an employer in cash, kind or as a facility is considered as income. For a businessman, his net profits will constitute income. Income may also flow from investments in the form of Interest, Dividend, and Commission etc. Infact the Income Tax Act does not differentiate between legal and illegal income for the purpose of taxation. Under the Act, all incomes earned by people are classified into five different heads, such as: income from salary, income from house property, income from business or profession, income from capital gains and income from other sources.
