Correcting a Mistake Apparent from Record: Filing a Section 154 Rectification Request

You e-filed your return for AY 2026-27 in July 2026, claimed a refund of Rs 30,000, and then the intimation under Section 143(1) landed showing a refund of Rs 0. Nothing in your income changed; the arithmetic simply did not carry a TDS credit that you were entitled to. This is the classic case for a rectification request under Section 154 of the Income-tax Act 1961 — a route to fix a "mistake apparent from record" without filing a revised return or an appeal. This guide walks through the statute, the exact portal path, and a worked example on a Rs 16,00,000 salary.

The Scenario

Assume a salaried reader, resident in India, with gross salary of Rs 16,00,000 for FY 2025-26 (AY 2026-27) taxed under the default new regime. The employer deducted salary TDS of Rs 1,13,100 across the year, and a bank deducted a further Rs 30,000 as TDS on fixed-deposit interest. The return, filed on 15 July 2026 and e-Verified the same day, claimed the Rs 30,000 excess as a refund.

The Centralised Processing Centre (CPC) issued an intimation under Section 143(1) dated 10 September 2026 that allowed only the Rs 1,13,100 of salary TDS and ignored the Rs 30,000 of bank TDS — because the bank had filed its Q4 TDS statement late and the credit was not yet reflected in Form 26AS. The net result: the computed refund collapsed from Rs 30,000 to Rs 0. The income was never in dispute; a credit visible in the Annual Information Statement simply had not synced when CPC ran the return.

That gap — a tax already paid but not counted — is exactly what Section 154 exists to correct. The Income Tax Department's own help page describes six rectification request types, and a "Tax Credit Mismatch Correction" is the one that fits a missing TDS entry rather than a dispute over how much tax is owed.

Statutory Answer

Section 154(1) of the Income-tax Act 1961 empowers an income-tax authority to "amend any order passed by it" to rectify "any mistake apparent from the record", including an intimation issued under Section 143(1). The threshold word is apparent: the Supreme Court held in T. S. Balaram, ITO v. Volkart Brothers (1971) 82 ITR 50 that a mistake apparent from the record must be "obvious and patent" and not one "which can be established by a long-drawn process of reasoning on points on which there may conceivably be two opinions". A missing TDS credit that a taxpayer can prove from Form 26AS clears that bar; a debatable claim about the head of income does not.

Four operative limbs of the section govern the mechanics. Section 154(3) requires that before any amendment which enhances an assessment, reduces a refund, or otherwise increases the taxpayer's liability, the authority must give notice and a reasonable opportunity of being heard. Section 154(1A) bars rectification of any matter that has already been "considered and decided" in an appeal or revision, which is why you cannot use Section 154 to reopen a point that a Commissioner (Appeals) has ruled on.

Timing is fixed by two more sub-sections. Section 154(7) sets an outer limit: no amendment may be made after four years from the end of the financial year in which the order sought to be amended was passed — so for an intimation dated 10 September 2026, the window runs to 31 March 2031. Section 154(8) protects the applicant: where the rectification is sought by the assessee, the authority must pass an order — amending or refusing to amend — within six months from the end of the month in which the application is received. An application filed in September 2026 therefore carries a statutory disposal deadline of 31 March 2027.

One procedural constraint from the portal itself: a fresh rectification request for the same assessment year and the same CPC order number cannot be filed until the previous request has been processed. You get one live request per order at a time, so it pays to select the correct request type before submitting.

Worked Resolution

Start with the tax that was actually due. Under the new regime for FY 2025-26, gross salary of Rs 16,00,000 less the Rs 75,000 standard deduction gives taxable income of Rs 15,25,000. The slab computation runs as follows.

Because taxable income of Rs 15,25,000 exceeds the Rs 12,00,000 ceiling, the Section 87A rebate (worth up to Rs 60,000 in the new regime for FY 2025-26) does not apply. You can reproduce this figure on the income tax calculator or the new regime calculator; both return Rs 1,13,100 for these inputs.

Now line up what was paid against what CPC counted.

The entire Rs 30,000 discrepancy is one missing credit, verifiable against the deductor's entry once the bank's TDS statement is processed. That is a mistake apparent from record, not a matter of judgement. The fix is a Tax Credit Mismatch Correction under Section 154, filed only after Form 26AS and the AIS actually show the Rs 30,000 — filing before the credit appears simply produces the same Rs 0 outcome.

The portal path, from the Income Tax Department's rectification help documentation, is: log in to the e-filing portal, then Services > Rectification > New Request, choose "Income Tax" as the tax type and "2026-27" as the assessment year, and pick the request type. The six income-tax request types are set out below.

For this scenario, "Tax Credit Mismatch Correction" (or, once the credit is visible, "Reprocess the Return") is correct. On submission CPC re-runs the computation, allows the Rs 30,000, and issues the refund. Interest under Section 244A is added at 0.5% per month; a refund granted in, say, December 2026 — nine months from 1 April 2026 — would carry roughly 4.5%, or about Rs 1,350, subject to any period of delay attributable to the taxpayer being excluded under Section 244A(2).

Complete e-Verification of the rectification request; an unverified request is not treated as filed, exactly as with the original return. You can sanity-check your own TDS figures against the TDS calculator before you submit, so the number you assert in the request matches the deductor's record.

FAQ

What is the difference between a Section 154 rectification and a revised return?

A revised return under Section 139(5) replaces your original return and is used when you made an error in the return itself; for AY 2026-27 it must be filed by 31 December 2026. A Section 154 rectification corrects a mistake apparent from record in the intimation or order — typically a processing error at CPC — and can be filed within four years of the end of the financial year in which the order was passed. Use 139(5) to change what you declared; use 154 to fix what CPC computed.

Can I file a Section 154 request if I disagree with an addition to my income?

No. A contested addition is a debatable matter, and under the Volkart Brothers (1971) 82 ITR 50 test it is not a mistake apparent from record. The correct remedy is an appeal to the Commissioner (Appeals) in Form 35 within 30 days of receiving the order — see our guide on filing Form 35 before CIT(A). Section 154(1A) also bars rectifying any point already decided in appeal.

How long does CPC have to act on my rectification request?

Section 154(8) requires the authority to pass an order within six months from the end of the month in which your application is received. An application filed in September 2026 must therefore be disposed of by 31 March 2027, whether the outcome is an amendment or a refusal.

Why did my TDS credit go missing in the first place?

Most commonly, the deductor (employer or bank) filed its quarterly TDS statement late or quoted the wrong PAN, so the credit had not reached Form 26AS when CPC processed your return. Check both 26AS and the AIS before filing; if the credit is still absent, the deductor must correct its TDS return before your Section 154 request can succeed.

Can the department rectify an order to my disadvantage?

Yes, but only with due process. Section 154(3) requires the authority to issue a notice and give a reasonable opportunity of being heard before any amendment that enhances the assessment, reduces a refund, or increases your liability. A rectification that only grants you a missing Rs 30,000 credit needs no such notice.

Can I file a second rectification for the same year?

Not while the first is pending. The portal blocks a fresh request for the same assessment year and CPC order number until the previous request is processed. Once that request is disposed of, you may file again if a further mistake apparent from record remains, provided you are within the four-year limit under Section 154(7).

Is interest paid on the delayed refund?

Yes. Under Section 244A, interest accrues at 0.5% per month (6% per annum) on the refund amount, generally from 1 April of the assessment year to the date the refund is granted, though any delay attributable to you is excluded under Section 244A(2). On a Rs 30,000 refund granted after nine months, that is roughly Rs 1,350.
