How to File a Revised ITR for AY 2026-27 (Step-by-Step)

You filed your return before July 31. Then you found a mistake; a missed deduction, a bank interest amount that was off, or a capital gain you forgot to include. The good news is that a filed return is not final. The Income Tax Act gives you an explicit window to correct it, and the process is not complicated once you know what you are doing.

This post walks through exactly how to file a revised ITR for AY 2026-27, who can do it, what the deadline is, and the specific steps on the portal.

What Is a Revised ITR and When Can You File One

A revised return under Section 139(5) lets you correct or update a previously filed return for the same assessment year. You can use it to add income you missed, claim a deduction you forgot, correct a wrong figure, or fix a wrong form selection.

The revised return replaces the original, it is not an addendum. When you file a revised return, the entire original return is superseded. Whatever figures appear in the revised return are what the department processes.

A few things to know before starting:

The return you want to revise must have been filed under Section 139(1), the original return. A belated return filed under Section 139(4) after July 31 can also be revised, so missing the July 31 deadline does not close the revision window. What matters is that the original or belated return was filed before you file the revision.

You cannot file a revised return if the department has already completed the assessment of your return under Section 143(3) (scrutiny assessment). Once an assessment order is passed, the window closes.

The deadline to file a revised ITR for AY 2026-27 is December 31, 2026, the same as the belated return deadline.

Common Reasons Taxpayers Need to Revise

Knowing why people revise helps you check whether your situation qualifies:

A bank issued a revised interest certificate after you filed. A mutual fund updated its capital gains statement. You received Form 16A from a second employer after filing on the basis of the first. You forgot to claim Section 80D premiums or Section 80G donations. You selected ITR-1 but had capital gains that required ITR-2. You reported a property transaction using the wrong cost of acquisition. Your employer issued a revised Form 16 after the company’s TDS return was corrected.

All of these are valid grounds for a revised return. The Income Tax Act does not require you to justify the revision, Section 139(5) simply says you may file one if you discover an omission or wrong statement.

If your original filing missed multiple income sources or had significant errors in AIS reconciliation, the post on AIS vs Form 26AS, what to reconcile before filing covers how those mismatches typically originate and what to clean up before you file the revision.

Step 1: Log In and Check Your Original Return Status

Go to incometax.gov.in and log in with your PAN and password. Under “e-File”, click on “Income Tax Returns” and then “View Filed Returns.” Find your AY 2026-27 return and check its status.

The status should say “Successfully e-verified” or “ITR processed.” If the return is still pending e-verification, complete that first. You cannot revise a return that has not been e-verified, because an unverified return is not treated as filed.

Note the acknowledgement number and the date of filing from the original return. You will need these when filling the revised return.

Step 2: Identify the Correct ITR Form

The revised return must use the same form as the original, or a different one if the original form was wrong.

If you filed ITR-1 but had capital gains, meaning you should have filed ITR-2 file the revised return in ITR-2. The system allows this. The correction of form is itself a valid reason to revise.

Step 3: Gather the Updated Documents

Before you open the form on the portal, have these ready:

The original return acknowledgement (ITR-V or the PDF downloaded from the portal). Updated Form 16 or Form 16A if the revision stems from a revised TDS certificate. Revised capital gains statement from your broker or registrar if the change involves securities. Updated bank interest certificates. Investment proofs for any deduction you are adding in the revised return. The corrected AIS or Form 26AS if the revision is because of a data mismatch.

Getting these in hand before starting avoids having to stop midway through the form.

Step 4: Start the Revised Return on the Portal

Log in and go to “e-File” and then “Income Tax Returns.” Click “File Income Tax Return.” Select Assessment Year 2026-27 and “Online” mode (or “Offline” if you are uploading a JSON prepared through the utility).

On the next screen, select “Revised Return – u/s 139(5).” This is the key selection, do not accidentally choose “Original” or “Belated.”

The portal will prompt you to enter the acknowledgement number and date of filing of the original return. Enter these exactly as they appear on your ITR-V or the filed return summary.

Step 5: Fill the Form with Corrected Figures

The revised return opens with the pre-filled data from the original return. Go through each section where the correction is needed and update the figures.

A few things to watch here:

Do not accept pre-filled data without checking it against your updated documents. If your AIS was updated after you filed the original return, the pre-filled figures in the revised return may reflect the updated AIS, which could be different from what you expect.

Enter the complete, correct figures in every schedule, not just the section you are changing. The revised return replaces the original entirely, so every schedule must carry the correct data, including sections where nothing changed.

If you are adding a deduction under Chapter VI-A, go to the relevant schedule and enter the deduction with the correct section and amount. For Section 80C deductions, ensure the total across instruments does not exceed ₹1.5 lakh. For Section 80D, check the premium amounts and the age-based limits.

If the revision is to correct capital gains, the most technically involved scenario recalculate the gain from scratch using the transaction statement from your broker or registrar. Use the correct cost of acquisition, sale consideration, and holding period. For equity mutual funds and listed shares, remember the LTCG exemption of ₹1.25 lakh per year applies from FY 2024-25 onwards. For STCG on equity, the rate changed to 20% from July 23, 2024. If your original return used the old 15% rate on transactions after that date, the revised return should correct it.

Step 6: Recheck the Tax Computation

After entering all corrections, go to the tax computation summary before submitting. Verify:

Total income matches the sum of all schedules. Deductions match the documents in hand. Tax liability is computed correctly after TDS credits, advance tax, and self-assessment tax paid. Refund or balance due matches your expectation.

If the revised return results in additional tax payable, pay the tax via Challan 280 before filing. A revised return with an unpaid tax demand gets flagged. Interest under Section 234B and 234C may also be due if the payment is being made late, factor this into the challan amount. If there is any uncertainty about which common ITR mistakes are most likely to carry over into a revision, the post on common errors to avoid when filing your ITR is a useful double-check.

Step 7: Submit and E-Verify

Once the form is complete and the computation is correct, submit the revised return. Immediately complete the e-verification do not wait. E-verification options are:

Aadhaar OTP (fastest and most reliable). Net banking EVC. Bank account pre-validation EVC. Demat account EVC.

The e-verification must be completed within 30 days of filing. If you do not verify, the revised return is not treated as filed and your original return remains on record.

After e-verification, download the revised ITR-V acknowledgement from “View Filed Returns.” Save it. This is your proof that the revised return was filed and verified.

What Happens After You File the Revised Return

The revised return replaces the original in all respects. The department processes the revised return, not the original. If a refund was due on the original return and the revised return changes the figure, the refund is adjusted accordingly.

If the original return had already generated a refund that was credited to your account, and the revised return reduces your refund entitlement, the excess refund becomes a demand on your account. The department will issue a notice for recovery if the difference is not settled.

If your original return was already selected for scrutiny under Section 143(2), a revised return can still be filed before the assessment is completed but inform your tax advisor, as the revision will need to be addressed within the scrutiny proceedings.

The department’s processing timeline for revised returns is broadly the same as original returns. Expect intimation under Section 143(1) within a few months of filing.

Multiple Revisions — Is That Allowed

Yes. Section 139(5) does not limit the number of times you can revise a return for a given assessment year. You can file a second revision if you find another error after filing the first. Each revision replaces the previous one, and each must be filed within the December 31, 2026 deadline.

Practically, filing multiple revisions can attract scrutiny attention. If your return changes significantly between revisions, be prepared with documentation that explains the changes.

When to Get Professional Help

Most salary-based revisions, adding a forgotten deduction, correcting a wrong bank interest figure are manageable on the portal. The form is the same, the process is identical to an original filing, and the portal walks you through it.

The situations that benefit from professional support are capital gain corrections (especially where the original return used wrong cost bases or misclassified holding periods), revisions involving foreign income or assets, revisions that also require advance tax recalculation, and cases where the original return is already under preliminary scrutiny.

If you need online ITR filing services or want to work with a tax consultant in India for the revision, or if you are looking for end-to-end income tax return filing services for AY 2026-27, getting the revised return right the first time avoids a second revision later.
