What is a section 143(1) intimation?

What is a section 143(1) intimation?

A section 143(1) intimation is the automated summary assessment sent after the Centralised Processing Centre processes your income tax return. It is issued under section 143(1) of the Income-tax Act, 1961, and it computes your total income, tax, interest and fee from the return you filed and the data the department already holds. It is not a scrutiny notice and it is not a penalty.

The intimation checks the return for a small, fixed set of prima-facie errors, applies any correction after telling you, and then states the result. Most returns are closed at this stage without any further contact from the department.

What do the three outcomes mean?

A section 143(1) intimation reports one of three outcomes: no change, a refund, or a demand. The outcome is the difference between the tax you computed in the return and the tax the Centralised Processing Centre computes on the same figures after the section 143(1)(a) adjustments.

A demand does not mean the return was wrong. It often comes from a tax credit mismatch or an arithmetical correction, and it can be contested rather than paid if the correction itself is wrong.

Which adjustments does 143(1)(a) allow?

Section 143(1)(a) of the Income-tax Act, 1961 allows only six prima-facie adjustments while processing a return. The Centralised Processing Centre cannot make a fresh addition outside this list at the 143(1) stage; anything beyond it needs scrutiny under section 143(3).

• An arithmetical error in the return.
• An incorrect claim apparent from information in the return.
• Disallowance of a loss claimed, where the return was furnished after the section 139(1) due date.
• Disallowance of an expenditure or increase in income indicated in the audit report but not taken into the return.
• Disallowance of a deduction claimed under sections such as 10AA or the 80-IA to 80-IE group, where the return was furnished after the due date.
• Addition of income appearing in Form 26AS, Form 16 or Form 16A that is not included in the return.

No adjustment under section 143(1)(a) is made unless an intimation of the proposed adjustment is first given to you in writing or electronically. If you do not respond within 30 days of that intimation, the adjustment is then made.

What is an incorrect claim apparent from the return?

An incorrect claim apparent from the return is one the return itself contradicts, not one that needs investigation. Section 143(1)(a) defines it, for example, as a claim that is inconsistent with another entry in the same return, or a deduction that exceeds a statutory limit stated as a monetary figure, percentage or ratio. It is a checkable inconsistency, not a matter of opinion.

What is the 143(1) time limit?

A section 143(1) intimation must be sent within nine months from the end of the financial year in which the return is furnished. That limit sits in the proviso to section 143(1) of the Income-tax Act, 1961. For a return furnished during the financial year 2025-26, that window ends on 31 December 2026, being nine months after 31 March 2026.

If no intimation is sent within that period, the acknowledgement of the return is deemed to be the intimation under section 143(1). In practice the Centralised Processing Centre processes most returns well before the limit expires.

How does 143(1) differ from scrutiny?

A section 143(1) intimation is automated processing; a section 143(2) notice opens a scrutiny assessment where the Assessing Officer examines the return in detail. They are different stages under different time limits, and a 143(1) intimation does not signal that scrutiny will follow.

When do I use section 154 instead?

Use section 154 when a 143(1) intimation carries a mistake apparent from the record, such as unclaimed TDS or a figure the processing read wrong. Section 154 corrects a plain mistake in an order or intimation already passed. It is not the route to make a fresh claim you never entered in the original return.

How do I respond to a demand?

1. Log in to the income tax portal and open the intimation from Pending Actions or the e-Filing dashboard.
2. Compare the returned figures against the computed figures column to find the exact line that changed.
3. If it is a proposed adjustment under section 143(1)(a), respond agreeing or disagreeing within 30 days, with supporting proof.
4. If the intimation is already final and carries a plain mistake, file a rectification request under section 154 for that assessment year.
5. If the demand is correct, pay it under the demand reference and keep the challan with the intimation.

How do I verify the intimation?

Verify a section 143(1) intimation on the income tax portal rather than from the email alone. The intimation is sent to your registered email and is also available after you log in, so the portal copy is the record to work from.

1. Open the intimation and match the document to your PAN and the correct assessment year.
2. Read the side-by-side columns of returned income and computed income to locate any adjustment.
3. Cross-check any tax credit difference against Form 26AS and the annual information statement for the same year.
4. Read the operative words of section 143 if the basis of an adjustment is unclear.

Why do 143(1) intimations get misread?

• Treating a 143(1) intimation as a scrutiny notice, when it is only automated processing.
• Paying a demand at once without checking whether the adjustment behind it is a correctable mismatch.
• Missing the 30-day window on a proposed adjustment under section 143(1)(a) and letting the change go final.
• Using section 154 to enter a fresh deduction, when it only corrects a mistake apparent from the record.
• Ignoring the intimation email and never opening the portal copy that carries the response option.

Where are 143(1) rule changes published?

Changes to return processing, the section 143(1)(a) adjustment set and the intimation time limit come through Finance Act amendments, CBDT circulars and e-Filing portal advisories. Complied AI keeps CBDT updates in one feed so you can open the source behind a change, and the income tax notice types guide sets the intimation beside the other sections a return can attract. When the exact wording matters, read section 143 on India Code next to the update. This guide is general information, not tax advice; see the disclaimer.
