What is Income Tax Filing in India? (Complete Guide)

Introduction

Income Tax Filing is the process of reporting an individual’s or business’s annual income, deductions, and tax liability to the Income Tax Department of India. It is governed by the Income Tax Act, 1961, and is mandatory for taxpayers whose income exceeds the basic exemption limit set by the government.

Taxpayers can file their returns through the official Income Tax e-Filing Portal at Income Tax e-Filing Portal, which is used for online income tax return filing in India. Every taxpayer must submit an Income Tax Return (ITR) for the relevant financial year (FY) and assessment year (AY). After successful filing, an ITR acknowledgement is generated as proof of submission.

India follows a self-assessment taxation system, where taxpayers calculate their own tax liability, pay applicable taxes, and file returns within the prescribed due dates.

Modern online tax filing in India has become easier with features such as:

Pre-filled ITR forms
Aadhaar-based e-verification
Integration with Form 26AS and AIS (Annual Information Statement)
