What is Income Tax (IT)?

Income-tax is a type of tax that the Indian Government imposes on the annual earnings of individuals and businesses during a financial year. This system is regulated by the Income Tax Act, 1961, which outlines the procedures for computing, assessing, and collecting income tax. 

Every taxpayer is legally required to file an ITR annually within the stipulated deadlines to disclose their income and, if eligible, claim refunds. ITRs can be submitted either online via the official Income Tax Department portal.

The Indian tax system also offers a range of deductions and exemptions that help reduce the overall tax burden for the financial year. Starting April 2026, the newly introduced Income Tax Act 2025 announced during the 2025 Union Budget will come into force.
