> One line summary: Filing your Income Tax Return (ITR) online is mandatory for most taxpayers, and this guide walks you through the entire process from gathering documents to submitting the form.

What is ITR and who needs to file it online?

An Income Tax Return (ITR) is a form you file with the Income Tax Department to declare your income, claim deductions, and calculate your tax liability. Under the Income-tax Act, 1961, any individual whose total income exceeds the basic exemption limit (₹2.5 lakh for individuals below 60 years for FY 2023-24) must file an ITR. Even if your income is below this limit, filing may be beneficial if you have tax deducted at source (TDS) or want to claim a refund. Filing online is mandatory for most taxpayers, except those who are eligible for the paper return option (typically senior citizens above 80 years or those with income below the exemption limit).

What documents do I need before I file ITR online?

Before you start, gather the following documents:

  1. Form 16 – Issued by your employer, showing salary income and TDS.
  2. Form 26AS – Available on the Income Tax e-filing portal, showing all TDS deducted on your behalf.
  3. Bank statements – For interest income, savings account interest, and fixed deposit interest.
  4. Investment proofs – For deductions under Section 80C (PPF, ELSS, life insurance), 80D (health insurance), etc.
  5. Home loan statements – If you have a home loan, for interest and principal repayment details.
  6. Capital gains details – If you sold any assets like shares, mutual funds, or property.
  7. Aadhaar number – Required for e-verification of the return.

Having these documents ready will save time and reduce errors.

How do I register on the Income Tax e-filing portal?

To file ITR online, you must first register on the official Income Tax e-filing portal (incometax.gov.in). Here’s how:

  1. Go to the portal and click on "Register".
  2. Select "Taxpayer" as the user type.
  3. Enter your PAN (Permanent Account Number) – this is mandatory.
  4. Provide your basic details: name, date of birth, mobile number, and email address.
  5. Create a password and set security questions.
  6. Verify your mobile number and email via OTP.
  7. Once registered, log in using your PAN and password.

After login, you can access your Form 26AS, file returns, and track refunds. If you already have an account, simply log in.

What is the step-by-step process to file ITR online?

Once logged in, follow these steps:

  1. Select the correct ITR form – For salaried individuals, ITR-1 (Sahaj) is usually applicable if your income is from salary, one house property, and other sources (up to ₹50 lakh). For income from capital gains or business, you may need ITR-2 or ITR-3. The portal will suggest the correct form based on your answers.

  2. Choose the assessment year – For FY 2023-24 (April 2023 to March 2024), the assessment year is 2024-25.

  3. Fill in your personal details – Name, PAN, address, date of birth, and Aadhaar number.

  4. Enter income details – Under "Income Details", add salary income (from Form 16), house property income, capital gains, and other sources (bank interest, etc.).

  5. Claim deductions – Under "Deductions", enter amounts for Section 80C, 80D, 80G (donations), and others. Ensure you have proofs for these.

  6. Calculate tax – The portal will automatically compute your tax liability based on the income and deductions entered. You can choose between the old tax regime (with deductions) and the new tax regime (lower rates, no deductions).

  7. Verify TDS – Cross-check TDS from Form 26AS with your entries. If there is a mismatch, correct it.

  8. Review and submit – Preview the entire return. If everything is correct, click "Submit".

  9. E-verify the return – After submission, you must verify the return. You can do this via Aadhaar OTP, net banking, or by sending a signed physical copy (ITR-V) to the CPC in Bengaluru within 120 days.

What are common mistakes to avoid when filing ITR online?

Beginners often make these errors:

  • Selecting the wrong ITR form – Using ITR-1 when you have capital gains or foreign assets can lead to a defective return.
  • Not reconciling Form 26AS – If TDS shown in Form 26AS does not match your entries, the department may issue a notice.
  • Forgetting to claim deductions – Many miss out on deductions like Section 80TTA (savings account interest up to ₹10,000) or 80EEA (home loan interest for first-time buyers).
  • Entering incorrect bank account details – Refunds are credited only to the bank account linked to your PAN. Ensure the IFSC and account number are correct.
  • Not e-verifying – A return is considered filed only after verification. If you miss this step, the return is invalid.

To avoid these, double-check all entries and use the portal's validation tools.

What should I do after filing ITR online?

After successful submission and e-verification, you will receive an acknowledgment (ITR-V) via email. Keep this for your records. The Income Tax Department typically processes returns within 30-45 days. You can track the status on the portal under "View Returns/Forms". If you are due a refund, it will be credited to your bank account. If you have any outstanding tax, pay it before the due date (usually July 31 for individuals) to avoid interest under Section 234A.

What You Should Do Next

If you are unsure about which ITR form applies to you or have complex income sources (capital gains, foreign income, business income), consult a qualified chartered accountant or tax professional. They can help you file accurately and avoid notices.
