ITR Filing Last Date 2026: Due Date, Penalty fees

ITR Filing Last Date 2026 (AY 2026-27): Due Date and Penalty

Knowing the deadline is only half the job. The other half is actually getting your return filed correctly before it arrives. This guide walks through what the ITR filing last date means for AY 2026-27, how extensions have played out in recent years, and the exact steps to file your return online without last-minute surprises.

What is the ITR Filing Last Date?

The ITR filing last date is the deadline set under Section 139(1) of the Income Tax Act by which you must submit your return for a given financial year. For FY 2025-26 (Assessment Year 2026-27), this deadline is no longer a single date for everyone. It now depends on your ITR form, whether an audit applies to you, and whether you have international transactions to report.

Due Date Table

Extension Updates

In previous years, the government has extended the ITR deadline more than once in the same season, sometimes at very short notice, usually due to technical issues on the e-filing portal. That history is one reason many taxpayers wait until the last few days.

For AY 2026-27, a few things are different. The staggered calendar itself, with separate dates for salaried and non-audit business taxpayers, is a built-in change rather than a temporary extension, so it is not something you should expect to shift further. Whether a further extension happens on top of these dates depends entirely on official announcements from the Income Tax Department closer to each deadline. Relying on a possible extension is a risky strategy, since fees and interest apply automatically from the day after the original due date if no extension is announced.

The practical takeaway: treat the dates in the table above as final unless you see an official notification on the income tax portal saying otherwise.

How to File ITR Online in 2026

Here is the process for filing online through the e-filing portal, applicable to most individual and small business taxpayers.

1. Log in to the e-filing portal at incometax.gov.in using your PAN as the user ID.
2. Check your pre-filled data. Salary, TDS, interest income, and some capital gains details are often pre-filled from Form 26AS and the AIS. Review this carefully rather than accepting it blindly.
3. Select the correct ITR form based on your income sources. If you are unsure, the portal's guided filing option helps identify the right form based on a short questionnaire.
4. Choose your tax regime. The new regime is the default for most taxpayers. If you want the old regime and have business or professional income, you generally need to file Form 10-IEA within the due date to opt out.
5. Enter or verify all income details, including salary, house property, capital gains, and any other income not already pre-filled.
6. Claim your deductions, applicable mainly under the old regime, such as Section 80C, 80D, and home loan interest.
7. Review the computed tax liability and pay any self-assessment tax due, including the Section 234F late fee if you are filing after the due date.
8. Submit the return.
9. E-verify within the required window, using Aadhaar OTP, net banking, or another available method. A return that is not e-verified in time is treated as though it was never filed.

Keeping Form 16, Form 26AS, AIS, bank statements, and investment proofs open in a separate tab while filing makes this process considerably faster.

Penalty for Late ITR Filing

If you file after your applicable due date, two costs typically apply:

• Late fee under Section 234F: Rs 5,000 if your total income exceeds Rs 5 lakh, or Rs 1,000 if it is up to Rs 5 lakh
• Interest under Section 234A: 1 percent per month on any unpaid tax, calculated from the day after the due date

Filing late can also restrict your ability to carry forward certain losses to future years, and it pushes back any refund you are owed, since processing begins only after the return is filed and verified.

FAQs

Can I file my ITR before the last date and still make changes later?

Yes, through a revised return under Section 139(5), available until 31 March 2027 for AY 2026-27, as long as your assessment has not already been completed.

Do I need to pay anything before filing if I am within the due date?

Only if you have outstanding self-assessment tax after accounting for TDS and advance tax already paid. Filing itself has no fee if done within the due date.

What happens if I forget to e-verify my return?

It is treated as though the return was never filed, so all late filing consequences would apply once the original window closes.

Should I wait for a possible extension before filing?

It is not advisable. Extensions are not guaranteed, and fees or interest apply automatically from the day after the original due date if no extension is announced.

Is the process different for business taxpayers requiring an audit?

Yes, the audit report needs to be filed a month before the ITR due date, and the return itself is prepared based on the audited financial statements, so the overall process typically starts earlier in the year.
