This guide offers a complete overview of income tax in India, including practical tips for filing and planning.
What is Income Tax?
Income tax is a tax levied by the government on an individual’s or entity’s income earned during a financial year. In India, the Income Tax Department under the Ministry of Finance is responsible for administering and collecting income tax. Income tax applies to various categories, including salaries, business profits, capital gains, property income, and other sources.
Who Should Pay Income Tax?
Income tax liability depends on the type of taxpayer and the annual income:

The basic exemption limit varies for different categories, and those earning below the threshold are not required to pay tax but may still need to file returns.
