What is Income Tax Return (ITR)?
An Income Tax Return (ITR) is an official form used by taxpayers to report their annual income, deductions, tax deductions, and tax liability to the Income Tax Department of India. Filing ITR is a legal obligation for individuals and entities whose income exceeds the basic exemption limit or who fall under specific categories mandated by the Income Tax Act, 1961.
The ITR form contains comprehensive details about your income from various sources such as salary, business/profession, house property, capital gains, and other sources. It also includes information about tax-saving investments under Section 80C, 80D, and other deductions, along with the total tax paid through TDS (Tax Deducted at Source), advance tax, or self-assessment tax.
