Income tax is one of the most important financial responsibilities for individuals and businesses in India. Understanding how income tax works helps you avoid penalties, plan your finances, and legally reduce tax liability. In this guide, we explain income tax in simple terms, based on practical experience and legal expertise.
What is Income Tax?
Income tax is a tax imposed by the Government of India on the income earned by individuals, companies, and other entities. It is governed by the Income Tax Act, 1961 and administered by the Income Tax Department under the Ministry of Finance.
Income tax applies to income earned from:
- Salary
- Business or profession
- House property
- Capital gains
- Other sources (interest, lottery, etc.)
Every eligible taxpayer must file an Income Tax Return (ITR) annually.

You must pay income tax if your annual income exceeds the basic exemption limit.
