What is an Income Tax Return (ITR)?

An Income Tax Return (ITR) is a form through which taxpayers report their income, deductions, tax payments, and other financial information to the Income Tax Department.

The purpose of filing an ITR is to:

• Report total annual income.
• Calculate income tax payable.
• Claim tax refunds.
• Carry forward eligible losses.
• Maintain legal compliance.
• Create financial proof for loans and visas.

Who Should File an ITR?

You should file an Income Tax Return if:

• Your total income exceeds the applicable basic exemption limit.
• Tax has been deducted from your salary (TDS).
• You want to claim a tax refund.
• You are a business owner or self-employed professional.
• You earn rental income.
• You receive capital gains from shares, mutual funds, or property.
• You have foreign assets or foreign income.
• You wish to carry forward business or capital losses.
• You are applying for loans or visas that require proof of income.

Benefits of Filing Income Tax Returns

Timely filing offers several advantages:

1. Easy Loan Approval

Banks usually ask for the last two to three years' ITRs while processing home, car, or business loans.

Business losses and capital losses can generally be carried forward only if the return is filed within the prescribed due date, subject to the provisions of the Income-tax Act.
