How to File a Rectification Request Under Section 154 on the Income Tax e-Filing Portal

You filed your return in July 2025, and weeks later a demand notice landed in your inbox for tax you were sure you had already paid. This is one of the most common post-filing shocks: an intimation under Section 143(1) that disallows part of your TDS credit or misreads a figure, leaving you with a demand you do not owe. The remedy is not a fresh appeal or a revised return. It is a rectification request under Section 154 of the Income Tax Act, 1961, filed directly on the e-Filing portal, and when the mistake is genuinely "apparent from the record" it can be resolved in weeks rather than the months an appeal would take.

The Scenario

Consider a salaried taxpayer whose Form 16 and Form 26AS both show that Rs 93,600 of TDS was deducted for FY 2024-25, yet the intimation issued under Section 143(1) on, say, 20 September 2025 credits only Rs 68,600 and raises a demand of Rs 25,000 plus interest. The cause is almost always mechanical: the deductor filed the Q4 TDS statement late or quoted a wrong PAN, so by the time the Centralised Processing Centre (CPC) in Bengaluru processed the ITR, the missing Rs 25,000 had not yet flowed into the taxpayer's tax credit statement.

Nothing in this dispute involves a difference of legal opinion. The taxpayer is not arguing about the taxability of an allowance or the head under which income falls. The record simply does not match the tax actually paid, and once the deductor corrects the TDS return, the credit appears in Form 26AS and the Annual Information Statement (AIS). That precise fact pattern is what Section 154 exists to fix.

Statutory Answer

Section 154(1) of the Income Tax Act, 1961 empowers an income-tax authority to amend any order passed by it, or any intimation or deemed intimation under Section 143(1), to correct "any mistake apparent from the record." The Supreme Court set the boundary of that phrase in T.S. Balaram, ITO v. Volkart Brothers (1971) 82 ITR 50, holding that a mistake apparent from the record must be an obvious and patent error, not one that requires a long-drawn process of reasoning or debate. A wrongly denied TDS credit, an arithmetical slip, or a figure picked up incorrectly from the return all qualify; a contested valuation does not.

Two timing rules govern the process. Under Section 154(7) of the Act, no amendment can be made after the expiry of four years from the end of the financial year in which the order sought to be rectified was passed. For an intimation passed on 20 September 2025, that four-year window runs to 31 March 2030. Section 154(8) protects the taxpayer at the other end: where the application is made by the assessee, the authority must pass an order either making the amendment or refusing it within six months from the end of the month in which the application is received. So a rectification filed on 10 October 2025 must be disposed of by 30 April 2026.

The e-Filing user manual published by the Income Tax Department states that only a registered user who has received an intimation under Section 143(1) from CPC Bengaluru may file a rectification, and that the request must be verified using a Digital Signature Certificate (DSC) or an Electronic Verification Code (EVC). Registered ERI users and authorised representatives may file on the taxpayer's behalf. Crucially, rectification lies against a processed return only; if your return is still under processing you must wait for the intimation before Section 154 becomes available. Where you disagree with a genuine legal position rather than an apparent error, the correct route is an appeal under Section 246A or, within the filing window, a revised return under Section 139(5).

Worked Resolution

Take the taxpayer above with a gross salary of Rs 14,75,000 for FY 2024-25, filing under the new tax regime. After the standard deduction of Rs 75,000 available to salaried employees, taxable income is Rs 14,00,000. Applying the FY 2025-26 new-regime slabs, the tax works out as follows.

Because taxable income of Rs 14,00,000 exceeds the Rs 12,00,000 rebate threshold, no Section 87A rebate applies, so the full Rs 93,600 is due. You can reproduce this figure using the Oquilia income tax calculator, and compare regimes on the old vs new regime calculator. The employer deducted and deposited exactly Rs 93,600, so on a correct record the tax payable and the credit cancel out to nil.

The intimation, however, allowed only Rs 68,600, creating the Rs 25,000 demand. Once the deductor revises the TDS statement and the full Rs 93,600 reflects in Form 26AS, the taxpayer logs in and follows Services > Rectification > New Request, selects the Income Tax Rectification option for AY 2025-26, and chooses the request type that matches the error. The portal offers three request types under income-tax rectification, summarised below.

In this case the taxpayer picks Tax Credit Mismatch Correction, confirms that Form 26AS now shows Rs 93,600, submits, and verifies with an EVC generated through the portal. CPC reprocesses the return, the Rs 25,000 demand is reduced to nil, and because the tax was in fact fully paid, any consequential tax refund carries interest under Section 244A at 0.5% per month. A confirmation is sent by email and SMS once the request is registered. If the mismatch instead sits in your salary TDS figures, verify them first against your payslips and the TDS calculator before submitting.

Before You File: Practical Checks

Three checks save the most rework. First, confirm the corrected figure actually appears in Form 26AS and AIS before you submit; filing a rectification while the record still shows the old figure only produces a fresh rejection. Second, note the Communication Reference Number printed on the Section 143(1) intimation dated in your case 20 September 2025, because the portal ties each rectification to a specific order. Third, remember the four-year outer limit under Section 154(7): even the most obvious error cannot be rectified after 31 March 2030 for an order passed in FY 2025-26, so do not let a demand sit unaddressed.

If CPC rejects the rectification or passes it against you, you are not out of options. You may file a second rectification if a further apparent mistake remains, or move to an appeal before the Commissioner (Appeals) under Section 246A within 30 days of the order. Keep every intimation, the revised Form 16, and the updated Form 26AS as your evidence trail.

FAQ

Is a rectification under Section 154 the same as a revised return?

No. A revised return under Section 139(5) lets you correct your own filing before the deadline and can change income, deductions or disclosures. A Section 154 rectification corrects a mistake apparent from the record in an order or intimation already passed by the department, such as a mis-computed TDS credit, and can be filed within four years of the end of the financial year in which that order was passed.

How long does CPC take to process a rectification?

The statutory ceiling under Section 154(8) is six months from the end of the month in which your application is received. In practice, straightforward reprocessing requests are often disposed of within a few weeks, but the six-month limit is your legal backstop: an application filed on 10 October 2025 must be decided by 30 April 2026.

Can I file a rectification if I have not received an intimation under Section 143(1)?

No. The Income Tax Department's e-Filing user manual requires that you have received an intimation under Section 143(1) from CPC Bengaluru before a rectification can be filed. If your return for AY 2025-26 is still under processing, wait for the intimation, then use the Services > Rectification path.

What is a "mistake apparent from the record"?

It is an obvious, patent error that needs no argument to establish, as the Supreme Court explained in T.S. Balaram, ITO v. Volkart Brothers (1971) 82 ITR 50. Examples include an arithmetical error, a TDS credit wrongly denied despite appearing in Form 26AS, or a figure incorrectly transcribed. A debatable point of law is not rectifiable under Section 154 and must go through appeal.

Will I get interest on a refund that arises from rectification?

Yes. Where a rectification reduces a demand to nil or creates a refund of tax already paid, interest under Section 244A of the Act is generally payable at 0.5% per month on the refund amount, subject to the conditions in that section. The credited refund and interest appear in your bank account after CPC reprocesses the return.

How do I verify a rectification request?

You verify using either a valid, registered Digital Signature Certificate (DSC) or an Electronic Verification Code (EVC) generated through the e-Filing portal, exactly as for return filing. A confirmation is sent to your registered email and mobile number once the request is successfully submitted.

What if the rectification is rejected or decided against me?

You may file another rectification if a distinct apparent mistake still exists, or appeal to the Commissioner (Appeals) under Section 246A within 30 days of the order. The four-year window under Section 154(7) continues to run from the end of the financial year in which the original order was passed, so act well before 31 March 2030 for an FY 2025-26 order.
