Intimation under Section 143(1) and Rectification: How to Read and Fix an Indian Tax Intimation

An intimation under section 143(1) is the first formal answer you get after filing an Indian income tax return. The Centralised Processing Centre (CPC) computes your tax, compares it with the credits it can see, and tells you whether you have a refund, a demand or no change. It is not an assessment, and most errors in it can be fixed by a rectification request. This guide covers the 1961 Act, which still applies to AY 2026-27 and earlier, and the matching provision of the Income-tax Act, 2025 for tax year 2026-27 onwards.

What is an intimation under section 143(1)?

Section 270(1) of the Income-tax Act, 2025 describes how a return is processed, and the 1961 Act's section 143(1) works in much the same way. The return is processed in this order:

1. The total income or loss is computed after adjustments for an arithmetical error, an incorrect claim that is apparent from the return, an inconsistency with information in the preceding year's return as prescribed, disallowance of a loss claimed where the earlier return was late, disallowance of expenditure or added income shown in the audit report but left out of the return, and disallowance of certain deductions where the return itself was late.
2. Tax, interest and fee are computed on that income.
3. The sum payable or refund is determined after credit for TDS, TCS, advance tax, rebate and relief (including foreign tax relief) and self-assessment tax.
4. An intimation is sent, and any refund is granted.

If no adjustment is made and nothing is payable or refundable, the acknowledgement of the return is treated as the intimation. For earlier years under the 1961 Act, the list of adjustments can also include adding income that appears in statements such as Form 26AS but was left out of the return, so compare the intimation with your tax statements as well as your return.

"Incorrect claim apparent from the return" is defined narrowly: a claim inconsistent with another entry in the same return, a claim for which the information required to substantiate it was not furnished, or a deduction above its statutory limit.

Common reasons a demand appears

• TDS credit mismatch: your return claims more TDS than appears against your PAN in Form 26AS, often because the deductor filed a wrong PAN or a late or incorrect statement.
• Late return: a fee of Rs 1,000 where total income is up to Rs 5 lakh and Rs 5,000 otherwise (section 234F of the 1961 Act, section 428 of the 2025 Act), plus interest.
• Loss disallowed because the return for the loss year was filed after the due date.
• Foreign tax credit claimed without the required statement or evidence (see foreign tax credit and Form 67).
• Deduction above the limit or lacking its supporting form.

How to read and respond to an intimation, step by step

1. Download the intimation from the e-Filing portal and note the assessment year, the date and the response deadline for any demand.
2. Compare two columns: "as per your return" and "as per intimation". Mark every difference.
3. Check your Form 26AS and AIS (see our portal, AIS and Form 26AS guide).
4. Decide the route. If the Department's computation is right, pay. If it overlooked a payment or made an error, file a rectification. If your own return was wrong, file a revised return before 31 March 2027 for AY 2026-27, or an updated return later.
5. If a demand is shown, record your response on the portal, and consider the Department's Demand Management Facilitation Centre if you are stuck. Do not ignore it: after 30 days from the demand notice, interest of 1% a month runs.
6. Track the outcome and download the rectified intimation when it is issued.

Rectification: how it works

The portal offers rectification options, including a request for "tax credit mismatch correction" and a request to "reprocess the return", each with a help video on the home page. Section 154 of the 1961 Act and section 287 of the 2025 Act govern the power:

• The authority can amend an order or an intimation to correct a mistake apparent from the record, on its own motion or when you, the deductor or the collector brings it to notice.
• An amendment that increases your liability or reduces a refund needs prior notice of the intention and a reasonable chance to be heard.
• If the amendment reduces the liability, the Assessing Officer makes the refund; if it increases it, a notice of demand follows.
• The time limit under the 2025 Act is four years from the end of the financial year in which the order or intimation was passed, and the authority should pass its order within six months of the end of the month in which the application was received.
• Rectification cannot reopen matters already decided in an appeal or revision.

For a processing error that needs more than rectification, the next stage is an appeal; see income tax appeals.

Why an Indian Chartered Accountant matters here

You can read an intimation yourself, but a Chartered Accountant (CA) saves time on the parts that are hard from abroad. The CA knows which rectification type matches your error, checks whether the mismatch really sits with a deductor, and can chase a buyer or customer in India to correct a TDS statement. The CA also decides whether a revised return, a rectification or an appeal is the right tool, because choosing the wrong one can burn a deadline. Our firm does not file in India, so we work with your CA on the U.S. side.

A worked example

A Pune company files its AY 2026-27 return on 28 October 2026 and claims TDS credit of Rs 3,00,000. Form 26AS shows only Rs 2,40,000 because a customer filed its statement late. The intimation, which can be issued up to 31 December 2027, shows a demand of Rs 60,000 plus interest. The company asks the customer to file a correction statement, waits for the credit to appear in Form 26AS, and files a tax-credit mismatch rectification attaching the Form 16A. The Department re-processes the return and issues a revised intimation with no demand.

Mistakes to avoid

• Paying a demand without checking the credit mismatch first
• Filing a rectification when the real issue is an error in your own return
• Ignoring a pre-intimation communication that proposes adjustments
• Waiting for the customer's TDS correction without a follow-up
• Forgetting the 30-day clock after a demand notice
