How to File ITR Online AY 2026-27: Complete Step-by-Step Guide

Filing your income tax return for AY 2026-27 is a largely pre-filled, online exercise on incometax.gov.in. The regular due date of 31 July 2026 for non-audit taxpayers has passed, so belated and revised returns are now the route for most people until 31 December 2026. This guide walks through every step, from logging in with your PAN to e-verifying the return.

Before You Start: PAN, Aadhaar and Records

Keep three basics ready before you open the portal. First, your PAN should be active and linked with Aadhaar, because an unlinked PAN blocks smooth filing and refund processing. Second, arrange your salary slips, bank statements and investment proofs. Third, download Form 26AS (Form 168 from tax year 2026-27), the Annual Information Statement (AIS) and the Taxpayer Information Summary (TIS) so you can reconcile figures later.

• Log in with your PAN as the user ID; the portal also accepts Aadhaar as the user ID.
• Reset a forgotten password using the OTP sent to your registered mobile and email.
• Confirm that PAN-Aadhaar linking is complete, since filing with an unlinked PAN creates validation trouble.

Step 1: Choose the Right ITR Form

Pick the form that matches your income profile for FY 2025-26. Most salaried residents with income up to ₹50 lakh use ITR-1 Sahaj, while capital gains or foreign assets push you to ITR-2 and business income to ITR-3 or ITR-4. Our form-by-form guide to ITR-1 through ITR-7 explains the eligibility rules in detail.

For AY 2026-27 the notified forms are realigned to the terminology of the Income-tax Act, 2025. Returns filed on old-format forms are rejected, so always download utilities and pre-filled data from the official portal only.

Step 2: Log In and Select the Assessment Year

Visit incometax.gov.in, log in with your PAN or Aadhaar and open the e-File menu. Choose Income Tax Returns, then File Income Tax Return, and select assessment year 2026-27. The portal offers an online mode with pre-filled data and an offline mode where you upload a JSON file generated from the offline utility.

Step 3: Review the Pre-filled Data Carefully

The portal pre-fills salary, TDS, interest, dividend and other data reported by your employer and banks. Match each figure with your Form 16 (Form 130 from tax year 2026-27), salary slips and bank certificates before accepting it. Pre-filled data is a convenience, not a guarantee, and the responsibility for correct figures remains with you.

Step 4: Reconcile with AIS and Form 26AS

Compare the return with Form 26AS, AIS and TIS before you submit. AIS often shows capital gains, mutual fund transactions and high-value transactions that never appear in Form 26AS. Report all taxable income even where no tax was deducted, because the department matches returns against these statements. Our comparison of AIS, Form 26AS and TIS explains how to read each statement.

Step 5: Claim Deductions and Check the Tax

Under the old regime you can claim Chapter VI-A deductions such as 80C, 80D and home loan interest, along with HRA exemption. The new regime for FY 2025-26 keeps only the ₹75,000 standard deduction and the employer NPS benefit under 80CCD(2). The portal computes tax as you enter figures, and any shortfall must be paid as self-assessment tax before submission.

Step 6: Preview, Submit and E-Verify Within 30 Days

Preview the return summary, accept the verification declaration and submit the return. The job is not finished yet, because the return counts as filed only after e-verification. Complete e-verification within 30 days of filing, using Aadhaar OTP, net banking, or an EVC through your pre-validated bank or demat account. If you miss the 30-day window, the return is treated as not filed and you must file again within the permitted period.

Missed 31 July 2026? Belated and Revised Returns

For AY 2026-27, a belated return under section 139(4) and a revised return under section 139(5) can be filed until 31 December 2026. A late fee under section 234F applies to belated filings: ₹5,000 where total income exceeds ₹5 lakh, and ₹1,000 where total income is up to ₹5 lakh. Interest on unpaid tax may also run from the original due date, so filing early beats waiting for the deadline.

If you spot an error after filing an original return on time, file a revised return before 31 December 2026. The revised return replaces the original and prevents a defective or demand notice later. Keep the acknowledgement number of the original return handy for the revision.

When to Take Professional Help

Multiple employers, capital gains, foreign assets or a department notice make DIY filing risky. A qualified practitioner can reconcile AIS data, select the correct form and respond to queries. Explore our income tax consultant services for assisted filing and notice support.
