Section 154 Rectification of Mistake: How to Fix Errors in Your Tax Order
Reviewed by CA Nikhil Gupta · Last reviewed 17 June 2026
You filed your ITR correctly, but the intimation under Section 143(1) shows a tax demand because TDS credit wasn't matched, or a deduction you claimed was disallowed due to a processing glitch. Before you panic and think about an appeal, check if this is simply a 'mistake apparent from the record' - because that's exactly what Section 154 rectification is designed to fix, quickly and without litigation.
What Is Section 154 Rectification?
Section 154 empowers an income tax authority to rectify any mistake apparent from the record in any order passed by it - including intimations under Section 143(1), assessment orders, and other orders. "Mistake apparent from the record" means an obvious and patent error that does not require any long-drawn process of reasoning or investigation of facts to establish - it must be glaring and self-evident from the existing record.
Common Examples of Mistakes Eligible for Rectification
| Type of Error | Example |
|---|---|
| TDS credit mismatch | TDS reflected in Form 26AS/AIS was not credited in the intimation, resulting in a demand that shouldn't exist |
| Arithmetical/computation error | Tax computed at the wrong rate, or addition/subtraction error in the intimation |
| Deduction wrongly disallowed | A valid Section 80C/80D deduction claimed in the ITR was not considered while processing |
| Advance tax/self-assessment tax not credited | Tax paid by the taxpayer (visible in Form 26AS) was not accounted for in the demand calculation |
| Carry-forward of losses not allowed | Losses correctly claimed and eligible for carry-forward were not reflected in the order |
| Clerical/typographical errors | PAN, assessment year, or amount entered incorrectly due to a data entry slip |
Who Can File a Rectification Request?
- The taxpayer - by filing an online rectification request on the income tax e-filing portal.
- The income tax authority itself - suo motu (on its own), if it notices a mistake in its own order.
How to File a Rectification Request Online
- Log in to the income tax e-filing portal (incometax.gov.in)
- Navigate to "Services" → "Rectification"
- Select the order/intimation you want rectified (e.g., the relevant assessment year's 143(1) intimation)
- Choose the appropriate rectification request type - common options include "Tax credit mismatch correction," "Return data correction (offline)," "Reprocess the return," and others depending on the nature of the error
- For tax credit mismatches, the portal often allows you to simply select the correct TDS/TCS/advance tax entries that should be matched
- Submit the request and e-verify it - you'll receive an acknowledgement number to track status
Time Limit for Filing Section 154 Rectification
Rectification vs Revised Return vs Appeal: When to Use What
| Situation | Correct Remedy |
|---|---|
| You made an error in your own ITR (wrong income reported, missed deduction, wrong bank account) before processing | File a Revised Return under Section 139(5), if within the time limit |
| The processed intimation/order contains an obvious factual/computational error not matching your correctly-filed return (e.g., TDS mismatch) | File a Rectification Request under Section 154 |
| You disagree with the AO's interpretation, addition, or disallowance based on judgment (a debatable legal/factual issue) | File an Appeal before CIT(Appeals) under Section 246A |
What Happens After You File a Rectification Request?
The tax authority reviews the request and the underlying record. If the mistake is found to be genuine and apparent, a rectification order is passed - either accepting the request (correcting the intimation/order and, if applicable, issuing a revised demand or refund) or rejecting it (with reasons). If rejected and you still believe there's an error, you may need to pursue other remedies such as an appeal, depending on the nature of the issue.
Rectification — obvious mistake, not a second appeal
Decision table
| Situation | 2026 treatment / control | Why it matters |
|---|---|---|
| Arithmetic/credit/obvious record error | Strong rectification candidate. | Attach the record proving the mistake. |
| Debatable interpretation | Usually needs appeal/revision/other remedy, not section 154. | Rectification is not a merits rehearing. |
| Rectification increases tax/reduces refund | Opportunity of hearing is required. | Track notice and response. |
| Old AY after 1 Apr 2026 | Transition provisions keep old-year rectification under the 1961 Act. | Do not switch section solely because application is filed later. |
Worked practical example
An intimation ignores a TDS credit clearly appearing in Form 26AS and the return claim. That can be an apparent-record issue. A dispute over whether a complex deduction is legally allowable is not automatically rectifiable.
