How to File a Revised Return under Section 139(5)

TL;DR

Time limit, scenarios where revision is permitted, and common mistakes that lock the original return.

Filing a revised return is one of the most commonly used provisions in income tax — nearly every year, some income goes unreported, a deduction is claimed incorrectly, or a TDS mismatch appears after filing. The Income Tax Act provides for this through Section 139(5), which allows taxpayers to correct errors in their filed return before the assessment is completed. But there are strict rules about when and how you can revise, and common mistakes can lock your original return in place with errors that cannot be corrected.

What Is a Revised Return

A revised return is a corrected version of an originally filed return. It replaces the original return entirely — the tax department discards the original and treats the revised return as the return filed for that assessment year.

The legal basis is Section 139(5) of the Income Tax Act, which states that a return can be revised by filing a revised return in the appropriate ITR form.

When Can You File a Revised Return

A return can be revised if:

1. You have already filed an original return
2. The return is filed using the correct ITR form
3. The return is filed within the prescribed time limit

Time Limit for Filing Revised Return: You can file a revised return any time before the end of the relevant assessment year OR before the assessment is completed by the department — whichever is earlier.

For FY 2024-25 (AY 2025-26):

• The assessment year runs from April 1, 2025 to March 31, 2026
• The last date to file a revised return is the earlier of: December 31, 2025 (end of the assessment year) or the date the assessment is completed
• In practice, assessment is completed for most returns within 12-18 months of filing

Example:

• You file ITR for FY 2024-25 on July 15, 2025
• On September 20, 2025, you discover you missed declaring a bank interest income of ₹20,000
• You can file a revised return up to December 31, 2025 (the end of AY 2025-26)
• If the department starts a scrutiny assessment before December 31, the window closes

Scenarios Where Revision Is Needed

1. Missed Income Discovered After Filing:

• A bank interest credit that appeared after you filed
• A dividend that was credited to your account after the filing date
• Salary from a previous employer that was paid after you filed
• Rental income received that you missed

2. TDS Mismatches:

• TDS reflected in Form 26AS that was not claimed in the original return
• TDS deducted by a bank or institution that appears after filing
• Excess TDS claimed that needs to be corrected

3. Incorrect Deductions Claimed:

• Claimed a deduction you are not eligible for (e.g., 80C investments that were not actually made)
• Claimed HRA but did not meet the eligibility criteria
• Claimed 80D for a health insurance policy that was not actually paid for

4. Wrong Tax Regime Selected:

• Filed under the old tax regime but wanted the new regime (or vice versa)
• The regime cannot be changed in a revised return if the original was filed correctly under the chosen regime — but errors in calculating the tax can be revised

5. Errors in Personal Details:

• Wrong bank account mentioned for refund
• Wrong address
• Incorrect filing status (e.g., wrongly filed as HUF instead of individual)

How to File a Revised Return

Step 1 — Log in to the Income Tax Portal Go to incometax.gov.in and log in with your credentials.

Step 2 — Navigate to e-File → Income Tax Returns → File Revised Return Select the Assessment Year and the original ITR form type that you filed.

Step 3 — Select “Revised Return” When starting the filing process, you must select “Revised Return” — not “Original Return.” The system will ask for the original acknowledgment number and the date of filing the original return.

Step 4 — Enter Original Return Details Enter the 15-digit acknowledgment number of the original return and the date of filing.

Step 5 — Make the Corrections Navigate to the section where the error exists and correct it. You can modify:

• Any income head
• Any deduction
• Personal details (bank account, address)
• Tax regime selection (within limits)

Step 6 — Recalculate Tax Use the “Calculate Tax” function to recompute the tax liability based on the corrected data.

Step 7 — Submit and E-Verify Submit the revised return and e-verify within 30 days using Aadhaar OTP, net banking, or bank account validation.

Belated vs Revised Return

Revised Return:

• Filed within the time limit (before end of AY or before assessment)
• Replaces the original return
• Any refund or additional tax liability is processed on the revised return

Belated Return (Section 139(9)):

• Filed after the original due date (e.g., filed after July 31 for non-audit cases)
• Does not replace the original — it is an additional filing
• You can also revise a belated return — a revised belated return can be filed within the time limit for belated returns

Key Difference: A belated return filed on time can be revised. A return filed under Section 148 (income escaping assessment) cannot be revised.

What Cannot Be Corrected in a Revised Return

• You cannot revise a return that was filed under Section 148 (the department has initiated an inquiry)
• A return that has already been processed and an intimation order issued can still be revised if within the time limit
• The ITR form must be the same as the original — you cannot switch from ITR-1 to ITR-2 in a revised return unless the switch is warranted by the correction

Common Mistakes That Cause Problems

Mistake 1 — Filing a Revised Return Instead of an Original Return: Always select “Revised Return” when correcting a filed return. If you file another “Original Return,” the system treats it as a fresh filing and may reject it as a duplicate or process it incorrectly.

Mistake 2 — Missing the Acknowledgment Number: You must have the 15-digit acknowledgment number of the original return to file a revised return. If you don’t have it, you can find it in your email, in the filed ITR, or by viewing your filing history on the income tax portal.

Mistake 3 — Missing the E-Verification Deadline: The revised return must be e-verified within 30 days of filing. If you don’t e-verify within 30 days, the revised return is treated as never filed.

Mistake 4 — Not Checking Form 26AS Before Filing: Form 26AS should always be downloaded and reconciled before filing the original return. If you find a TDS entry in Form 26AS that was missed, check whether the original return has been processed before filing a revised return — if it has been processed, the revised return can correct it.

Mistake 5 — Thinking the Assessment Has Already Been Completed: The assessment is completed by the Assessing Officer — it is not the same as processing. If a notice has been issued under Section 143(2) or 147, the assessment process has begun. Filing a revised return in this situation requires caution — consult a CA before revising.

After Filing the Revised Return

Processing: The revised return is processed by the CPC just like the original return. The CPC will compare the revised return with the original return to identify changes.

Refund or Additional Tax:

• If the revised return shows additional tax payable: Pay the additional tax with interest (if late) to avoid further interest charges
• If the revised return shows a higher refund: The additional refund will be processed separately after the revised return is processed
• If the revised return shows less refund: The excess refund already issued will be recovered

Acknowledgment: After filing the revised return, you receive a new acknowledgment number. This is different from the original acknowledgment number.

How to Avoid the Need for Revision

The best revision is the one you never have to file. Before filing your ITR:

1. Download Form 26AS and reconcile every TDS entry with your records
2. Download AIS (Annual Information Statement) to check all income reported against your PAN
3. Verify your 26AS and AIS before filing — these show income that has been reported by third parties (employers, banks, tenants, etc.)
4. Collect all investment proofs before claiming deductions — don’t claim 80C investments you haven’t actually made
5. Double-check your bank account number and IFSC for the refund — wrong bank details delay refunds
6. Choose the right tax regime before filing — switching between regimes in a revised return is restricted

Penalties for Incorrect Returns

If the revised return reveals that the original return was filed with incorrect information that was previously known to the taxpayer:

• The department may impose a penalty under Section 271F for concealment or furnishing inaccurate particulars
• In severe cases, prosecution under Section 276C for tax evasion may be initiated

However, if the error was genuine (e.g., income discovered after filing from a bank that credited interest late), the revised return corrects it without penalty.
