File ITR Online 2026: Step-by-Step Guide
Filing your income tax return (ITR) is mandatory if your income exceeds the basic exemption limit. Learn which ITR form applies to you, what documents to keep ready, the July 31 deadline, and exactly how to e-file at incometax.gov.in.
Every July, millions of salaried Indians panic-file their ITR on the last day — only to discover their PAN isn't linked to Aadhaar and the portal won't let them proceed. What surprises most people is that the Income Tax Department already has your salary, bank interest, and mutual fund data through AIS — your job is really just to review and confirm it, not to fill everything from scratch. I researched this thoroughly so you don't spend three evenings staring at a confusing portal.

Common Problems & Solutions
Frequently Asked Questions
What is the last date to file ITR for FY 2025-26 (AY 2026-27)?
The due date for salaried individuals and non-audit cases is July 31, 2026. Businesses requiring audit have a due date of October 31, 2026. Missing the deadline attracts a late fee of ₹1,000 (income below ₹5L) or ₹5,000 (income above ₹5L) under Section 234F.
Which ITR form should a salaried employee file?
ITR-1 (Sahaj) is for salaried individuals with total income up to ₹50 lakh from salary, one house property and other sources. If you have capital gains or more than one house property, use ITR-2. ITR-3 is for business/professional income.
Is it mandatory to file ITR if income is below the taxable limit?
Legally, filing is mandatory only if gross income exceeds the basic exemption (₹2.5L/₹3L/₹5L). However, filing is recommended even if no tax is payable — it is required for loans, visas, and to carry forward losses.
How do I e-verify my ITR?
The easiest method is Aadhaar OTP — go to e-Verify Return on the portal, select Aadhaar OTP, and enter the OTP sent to your Aadhaar-linked mobile. Alternatively, use Net Banking EVC, Bank Account EVC, or send the printed ITR-V by speed post to CPC Bengaluru within 30 days.
Can I file a revised ITR after submission?
Yes. Under Section 139(5), you can file a revised return to correct mistakes. The deadline is December 31 of the assessment year (December 31, 2026 for AY 2026-27). There is no limit on the number of revisions within this period.
What is AIS and do I need to check it before filing?
The Annual Information Statement (AIS) aggregates all financial transactions reported to the Income Tax Department — including salary, dividends, interest, mutual fund transactions, and high-value purchases. Always review AIS before filing to ensure your return matches reported data and to avoid scrutiny notices.
What happens if I don't file ITR by the due date?
A late fee of up to ₹5,000 under Section 234F applies. Additionally, interest under Section 234A (1% per month) is charged on unpaid tax. You also lose the ability to carry forward capital or business losses, and may face difficulty with loan and visa applications.
Is Form 16 mandatory to file ITR?
Form 16 is not legally mandatory to file ITR — it is a TDS certificate your employer is required to give you. However, it contains key salary breakup and TDS details that make filing much easier. If you don't have it, you can use Form 26AS and AIS to get the same information.
