Step-by-Step Guide to Filing Income Tax in India for 2025

Filing an Income Tax Return (ITR) is a vital responsibility for every eligible taxpayer in India. It not only ensures compliance with the Income Tax Act, 1961, but also streamlines financial transactions like securing loans, applying for visas, or obtaining credit cards. For the Financial Year (FY) 2024-25, corresponding to the Assessment Year (AY) 2025-26, the Central Board of Direct Taxes (CBDT) has extended the ITR filing deadline to September 15, 2025, providing taxpayers ample time to file accurately. This comprehensive guide will walk you through the step-by-step process of filing your income tax return in India for 2025, whether online or offline, with practical tips to ensure a hassle-free experience.

Why Filing ITR is Important

Filing your ITR is more than a legal obligation—it’s a cornerstone of financial planning. Here’s why it matters:

  • Legal Compliance: Filing ITR is mandatory for individuals whose income exceeds the basic exemption limit or who meet specific criteria, such as foreign travel expenses exceeding ₹2 lakh or deposits above ₹1 crore in current accounts.
  • Financial Transparency: It provides a record of your income and taxes paid, which is essential for loan approvals, visa applications, or other financial transactions.
  • Claim Refunds: If excess tax has been deducted (e.g., TDS), filing an ITR allows you to claim refunds.
  • Avoid Penalties: Late or non-filing can lead to penalties, interest, or invalidation of your return.

With the extended deadline for AY 2025-26, now is the perfect time to get organized and file your ITR accurately. Let’s dive into the step-by-step process.

Step-by-Step Guide to Filing ITR Online

Step 1: Register or Log In to the E-Filing Portal

  • Visit the official Income Tax e-filing portal (www.incometax.gov.in).
  • If you’re a new user, register using your Permanent Account Number (PAN) as your user ID.

Step 4: Choose the Appropriate ITR Form

Selecting the correct ITR form is crucial. The form depends on your income sources and taxpayer category. Here’s a quick overview:

  • Tax Paid: Confirm taxes paid (TDS, TCS, advance tax, or self-assessment tax) as per Form 26AS.

Step 8: Compute Tax Liability

  • Review the total tax liability based on your income, deductions, and chosen tax regime.
  • If there’s a tax payable, click Pay Now to use the e-Pay Tax service. After payment, click Back to Return Filing.
  • If there’s no tax liability or you’re eligible for a refund, proceed to the next step.

Step 9: Preview and Validate

  • On the Preview and Submit Your Return page, review all entries, including tax computation and deductions.
  • Select the declaration checkbox (confirming no involvement of a Tax Return Preparer if applicable).
  • Click Proceed to Validation to check for errors.

Step 10: Submit and E-Verify

  • After validation, click Submit.
  • E-verify your return within 30 days using one of these methods:
    • Aadhaar OTP: Receive an OTP on your Aadhaar-linked mobile.
    • Electronic Verification Code (EVC): Generate via pre-validated bank accounts or Demat accounts.
    • Digital Signature Certificate (DSC): For specific taxpayers.
