Revised Return u/s 139(5): How to Correct a Filed ITR Before 31 December

If you filed your Income Tax Return for FY 2025-26 and later noticed a mistake — a missed bank interest entry, a wrong deduction claim, or a typo in your PAN-linked bank account — you do not need to panic. Section 139(5) of the Income Tax Act gives you a clear legal right to file a revised return and correct those errors. The deadline is 31 December 2026, and there is no fee or penalty just for revising. This article walks you through exactly how it works, with numbers, a comparison table, and the mistakes you must avoid.

What Is a Revised Return u/s 139(5)?

Section 139(5) allows any person who has already filed a return u/s 139(1) — the original return — to file a fresh, corrected return if they discover any omission or wrong statement in the original. The revised return legally supersedes the original. Once you file the revision, the Income Tax Department processes only the revised return.

Key points to remember:

• Only returns originally filed u/s 139(1) can be revised. A return filed belatedly u/s 139(4) can also be revised — the law was amended to allow this.
• You can revise as many times as needed before the deadline.
• The deadline for revising a return for FY 2025-26 (AY 2026-27) is 31 December 2026.
• No separate form is needed — you file on the same ITR form (ITR-1, ITR-2, etc.) and select "Revised Return u/s 139(5)" in the filing type dropdown.

Deadline and Key Dates at a Glance

Note: If the government extends any deadline via notification, the revised return deadline typically shifts automatically to match.

Worked Example — Salaried Taxpayer Who Missed Bank Interest

Let us take a concrete case. Priya is a salaried employee in Pune earning ₹12,00,000 per year (gross). She filed her ITR-1 on 20 July 2026 but forgot to include ₹45,000 of savings account interest she earned across two banks.

Here is how the numbers change:

Priya pays ₹7,500 extra tax via Challan 280 (self-assessment tax) before filing the revised return, and interest u/s 234B may apply on this shortfall from the assessment date. By revising, she avoids a potential notice for under-reporting income — which carries far heavier consequences under section 270A.

Step-by-Step: How to File a Revised Return on the Income Tax Portal

1. Log in to the Income Tax e-filing portal (incometax.gov.in) with your PAN and password.
2. Go to e-File → Income Tax Returns → File Income Tax Return.
3. Select Assessment Year 2026-27 and the appropriate ITR form.
4. Under "Filing Type," choose Revised Return u/s 139(5).
5. Enter the Acknowledgement Number (15-digit) and Date of Filing of your original return — you will find these in the ITR-V you received.
6. Make all corrections — income, deductions, bank details, whatever was wrong.
7. If the revision creates additional tax liability, pay it via Challan 280 before submitting. Enter the challan details in the tax paid schedule.
8. Submit and e-verify within 30 days using Aadhaar OTP, Net Banking, or TOTP. An unverified return is treated as invalid.

What You Can and Cannot Correct

You can correct: omitted income, wrong deduction amounts, incorrect bank account numbers, wrong personal details, missed TDS credit claims, wrong ITR form selection (by filing the correct form as the revised return).

You generally cannot use a revised return to: switch from the new tax regime to the old tax regime if the option was exercised in the original return (specific conditions apply — consult a CA), or revise after 31 December 2026 (use Section 139(8A) Updated Return instead, with a 25%–50% additional tax on the tax and interest due).

Common Mistakes People Make When Filing a Revised Return

• Mistake 1 — Filing as a fresh/original return: Many taxpayers accidentally select "Original" instead of "Revised u/s 139(5)" in the filing type. This creates duplicate return records and confuses processing. Always select "Revised."
• Mistake 2 — Leaving the original acknowledgement number blank: The portal requires the 15-digit acknowledgement number of the return you are replacing. Without it, the revision is not linked and may be treated as a defective return.
• Mistake 3 — Not e-verifying the revised return: Filing without verification means the revised return has no legal standing. Your original (potentially incorrect) return continues to be the one on record.
• Mistake 4 — Not paying the additional tax before revising: If your revision increases taxable income, pay the self-assessment tax via Challan 280 first and enter the BSR code and challan details in the return. Submitting without this creates an outstanding demand.
• Mistake 5 — Assuming a revised return resets the refund clock entirely: Refund processing time may lengthen after revision since the department re-processes the return. File early — do not wait until late December and then expect a quick refund.

Revised Return vs. Updated Return — Which One Do You Need?

If you miss the 31 December 2026 deadline, Section 139(8A) allows an Updated Return within two years from the end of the assessment year. But it comes at a cost — an additional tax of 25% of the aggregate of tax and interest due if filed within 12 months, rising to 50% if filed in the second year. You also cannot use it to claim a refund or reduce your tax liability. The revised return u/s 139(5), by contrast, is free of these restrictions. Filing it on time is always the better option.

Frequently asked questions

Can I file a revised return if I filed a belated return after 31 July?

Yes. After an amendment to the Income Tax Act, even a belated return filed u/s 139(4) can be revised u/s 139(5), as long as the revision is filed before 31 December 2026.

How many times can I revise my ITR?

There is no statutory limit. You can revise as many times as needed before the 31 December deadline. Each revised return replaces the previous one completely.

Will I get a penalty for filing a revised return?

No penalty is levied simply for revising a return. However, if the revision reveals additional tax liability, interest u/s 234B or 234C may apply on the shortfall. If the department determines you had under-reported income willfully, separate penalty proceedings under section 270A could apply — but voluntary revision is generally viewed favourably.

What if I realise I overclaimed a deduction and want to reduce my refund claim — should I still revise?

Yes, you should revise even if it means a lower refund or higher tax payable. Leaving an incorrect deduction in the return creates a mismatch with Form 26AS or AIS data and increases the likelihood of a scrutiny notice. Proactive correction through a revised return is always safer.
