What is Income Tax Return (ITR)?

An Income Tax Return (ITR) is a form through which taxpayers declare their income, deductions, taxes paid, and other financial details to the Income Tax Department of India. Filing an ITR is mandatory for individuals and businesses whose income exceeds the prescribed exemption limit under the Income Tax Act.

ITR filing helps taxpayers:

  • Report their income legally
  • Claim tax refunds
  • Carry forward losses
  • Apply for loans and visas
  • Avoid penalties and notices from the Income Tax Department

Income Tax Returns are filed online through the official income tax portal.

Who Should File an ITR?

The following persons are generally required to file Income Tax Returns:

A. Individuals with Taxable Income

If your total income exceeds the basic exemption limit:

Category Exemption Limit
Individual below 60 years ₹2.5 Lakhs
Senior Citizen (60–80 years) ₹3 Lakhs
Super Senior Citizen (80+ years) ₹5 Lakhs

B. Mandatory Filing Even if Income is Below Limit

ITR filing is compulsory if a person:

  • Deposits more than ₹1 crore in a current account
  • Spends more than ₹2 lakhs on foreign travel
  • Pays electricity bills exceeding ₹1 lakh
  • Has TDS/TCS above prescribed limits
  • Owns foreign assets or foreign bank accounts
