Filing an Income Tax Rectification Under Section 154

Income Tax Rectification (Section 154/287): How to File Online

You filed your ITR, received the Section 143 1) intimation, and the numbers do not match your computation. The CPC shows a demand of Rs 15,000, but your return showed a refund of Rs 8,500. The TDS credit from Form 26AS is missing, or the Section 87A rebate was not applied, or the CPC picked up the wrong income figure from Schedule OS.

This happens every year to lakhs of taxpayers. The fix is a rectification request under Section 154 (or Section 287 under the new Income Tax Act, 2025). It is not a revised return. It is not an appeal. It is a request to correct a specific, clear error in the order passed by the income tax authority.

This guide covers what qualifies for rectification, the three types of online requests, the step-by-step filing process, and the time limits that apply for AY 2026-27.

Section 154 vs Section 287: What Changed

The Income Tax Act, 2025 replaced the Income Tax Act, 1961 with effect from April 1, 2026. The rectification provision moved from Section 154 to Section 287.

The substantive provisions are identical. Section 287 is a textual consolidation, not a policy change. All the settled case law on "mistake apparent from the record" carries over.

If you received a 143 1) intimation for AY 2025-26 (processed before April 1, 2026), your rectification is under Section 154. If you receive a 270 1) intimation for AY 2026-27, your rectification is under Section 287. The online process on the e-filing portal is the same for both.

What Qualifies as a "Mistake Apparent from the Record"

This is the single most important threshold. A rectification request is not a second chance to argue your case. It can only correct errors that are glaring, obvious, and require no investigation or debate to identify.

What qualifies:

• Arithmetical errors in the CPC computation (addition, subtraction mistakes)
• TDS or TCS credit available in Form 26AS/AIS but not considered by CPC during processing
• Section 87A rebate not applied despite total income being within the Rs 12,00,000 limit (new regime)
• Wrong income figure picked up from a schedule (CPC imported an incorrect number from your XML)
• Clerical errors such as wrong PAN, wrong assessment year, or wrong bank account in the refund order
• Failure to apply a clearly established legal provision (for example, standard deduction of Rs 75,000 not given under new regime)
• Double counting of income already reported under the correct head

What does NOT qualify:

• A debatable interpretation of whether a particular income is taxable under one head or another
• Disagreement with the CPC's treatment of a deduction where two views are possible
• Fresh claims that were not made in the original return (use a revised or updated return instead)
• Re-computation involving extensive fact-finding or investigation
• Matters already decided in an appeal or revision proceeding

The Supreme Court has consistently held that a mistake apparent from the record must be an error so patent that it can be detected at a glance, without a long-drawn process of reasoning.

Three Types of Rectification Requests on the E-Filing Portal

The e-filing portal (incometax.gov.in) offers three types of rectification requests. Choosing the right type is critical because the wrong selection can lead to rejection.

1. Reprocess the Return

When to use: You filed the correct return with all the right figures, but the CPC processed it incorrectly. The data in your ITR is accurate; the CPC's computation is wrong.

Common scenarios:

• CPC did not consider the latest revised return and processed an older version
• TDS credit from Form 26AS was available at the time of processing but CPC missed it
• CPC applied the old tax regime instead of the new regime (or vice versa) despite your Form 10-IE / Form 122 choice

How it works: You do not upload any new data. You simply request the CPC to reprocess your existing return. The CPC picks up the return XML again, cross-checks it against current 26AS/AIS data, and recomputes the tax.

Best for: Cases where your return data was correct all along.

2. Tax Credit Mismatch Correction

When to use: The TDS/TCS/advance tax/self-assessment tax details in your return do not match what the CPC has on record, and you need to correct the tax credit schedules.

Common scenarios:

• Employer deposited TDS but the challan details (BSR code, challan serial number, date) in your return have a typo
• You paid advance tax but entered the wrong challan details in the ITR
• TCS credit is missing because the collector filed the TCS return late, and the credit now reflects in 26AS

How it works: The portal auto-populates TDS/TCS/challan schedules from your processed return. You edit the incorrect entries with the correct BSR code, challan serial number, or amount. You cannot change income figures here; only tax credit details.

Best for: Mismatches between Form 26AS and the tax credit entries in your return.

3. Return Data Correction (Offline/Online)

When to use: You need to correct income data, schedule entries, or other return fields, provided the changes do not alter the gross total income and claimed deductions. For example, income reported under "Other Sources" should have been under "Business/Profession" or vice versa.

Common scenarios:

• Income shown under the wrong head (Schedule OS instead of Schedule BP, or Schedule CG instead of Schedule OS)
• Personal information corrections (bank account, address, email)
• Schedule-level adjustments where the total income and deductions remain unchanged

How it works: You download the ITR offline utility, make corrections in the XML/JSON, and upload the corrected file through the rectification portal. The portal handles that gross total income and deductions match the original.

Step-by-Step: How to File a Rectification Request Online

Prerequisites Before Filing

Before you start the rectification process, confirm the following:

1. Return is already processed. Rectification is available only after the CPC has issued the 143 1) or 270 1) intimation. If processing is pending, wait for the intimation.

2. No previous rectification request is pending. The portal does not allow a new rectification request while an earlier one for the same AY is still being processed. Check under Services > View Filed Forms > Rectification to confirm the status.

3. You have the Communication Reference Number. This is mandatory. Without it, you cannot proceed. Find it in the intimation order sent to your registered email or on the portal under e-Filed Returns > View Filed Returns > select the AY > download the intimation.

4. No appeal is pending on the same issue. If you have already filed an appeal on a particular point, you cannot file a rectification request on the same point. Section 154 1A) (old Act) and Section 287 (new Act) both exclude matters already under appeal or revision.

5. Download the latest ITR offline utility (for Return Data Correction only). The offline utility version must match the AY you are correcting. Download from the Downloads section of the e-filing portal.

Time Limits You Must Know

Practical example: Your AY 2025-26 return was processed on September 15, 2025. The 143 1) intimation was passed in FY 2025-26. You have until March 31, 2030 4 years from end of FY 2025-26) to file a rectification request.

Practical example for new Act: Your AY 2026-27 return is processed on October 10, 2026. The 270 1) intimation is passed in FY 2026-27. You have until March 31, 2031 to file a rectification under Section 287.

Common CPC Errors That Trigger Rectification Requests

Here are the scenarios most taxpayers encounter when their 143 1)/270 1) intimation shows a mismatch:

1. TDS Credit Not Allowed

Symptom: CPC shows lower TDS credit than what appears in your Form 26AS/AIS.

Cause: The deductor filed or revised the TDS return after the CPC processed your ITR. Or the BSR code, challan serial number, or deduction date in your ITR does not match the deductor's TDS return.

Fix: Verify Form 26AS on the TRACES portal. If the TDS is now reflecting correctly, file a "Reprocess the Return" request. If there is a challan detail mismatch, file a "Tax Credit Mismatch" request and correct the BSR code/serial number/date.

2. Section 87A Rebate Not Applied

Symptom: CPC computed tax liability without applying the Rs 60,000 rebate (new regime) even though your total income is below Rs 12,00,000.

Cause: CPC's automated processing sometimes misapplies the rebate when there are special rate incomes (LTCG, STCG under Section 111A/112A). The rebate is not available on such incomes, and the CPC may have correctly excluded them from the rebate calculation. Verify first.

Fix: If the rebate was genuinely missed (total income excluding special rate incomes is within the limit), file a "Reprocess the Return" request.

3. Wrong Tax Regime Applied

Symptom: CPC computed tax under the old regime, but you opted for the new regime (or vice versa).

Cause: Form 10-IE / Form 122 was not filed, or was filed after the return was processed, or the regime indicator in the ITR XML did not match.

Fix: If you filed Form 10-IE / Form 122 before the due date and the ITR shows the correct regime, file "Reprocess the Return." If the form was not filed, rectification may not help; you may need to file a revised return (if the due date has not passed) or an appeal.

4. Advance Tax/Self-Assessment Tax Not Credited

Symptom: CPC shows a demand because your advance tax or self-assessment tax payment is not reflected.

Cause: Challan details in the ITR do not match the OLTAS records. Common errors: wrong BSR code, wrong date of deposit, wrong minor head code.

Fix: Verify the challan on the e-Pay Tax section of the portal. File a "Tax Credit Mismatch" request and correct the challan details.

5. Double Addition of Income

Symptom: CPC added income from one schedule twice, inflating the total income beyond what your return showed.

Cause: Processing error at CPC, or a mismatch between the AIS data the CPC relied on and your reported figures.

Fix: File "Reprocess the Return." If the issue is in your ITR data itself (you entered the figure twice by mistake), file "Return Data Correction."

What Happens After You File

1. Acknowledgment: The portal generates a transaction ID and sends a confirmation to your registered email and mobile.

2. Processing: CPC handles the rectification request. For "Reprocess" requests, the CPC reprocesses the original ITR XML against current 26AS data. For other types, the CPC handles the corrected data.

3. Outcome: CPC issues a revised intimation under Section 154/287. The revised intimation may show:

   • Refund due: If the original demand is reduced or reversed, the refund is processed to your bank account.
   • Reduced demand: If the demand is partially corrected.
   • Rejection: If the CPC does not find a mistake apparent from the record. You will receive a rejection order with reasons.

4. If rejected: You can file a fresh rectification request (if the issue is genuinely a mistake apparent from the record and you believe the CPC missed it), or file an appeal under Section 246A (old Act) / Section 352 (new Act) if you disagree with the rejection.

Rectification vs Revised Return vs Updated Return

Can the Income Tax Authority Rectify Suo Motu?

Yes. Section 154 1)/287 allows the income tax authority to rectify its own order without waiting for a taxpayer's application. This can go both ways:

• In your favor: The CPC or AO discovers an arithmetical error in the assessment and issues a corrected order reducing your demand or granting a refund.
• Against you: The authority discovers that a credit was wrongly given, or an exemption was incorrectly applied. Before passing such an order, the authority must issue a notice and give you an opportunity of hearing.

The same 4-year time limit applies to suo motu rectification.

Tracking Your Rectification Status

After filing, track the status through:

1. E-filing portal: Log in to incometax.gov.in > Services > Rectification > View Filed Rectification Requests. The status will show as Submitted, Under Processing, Rectification Order Passed, or Rejected.

2. Email/SMS: The portal sends updates at each stage to your registered email and mobile number.

3. Expected timeline: Most rectification requests are processed within 30 to 90 days. Complex cases involving manual verification may take longer, but the CPC must dispose of the request within 6 months from the end of the month of filing.
