Section 143(1) Intimation: What It Means and How to Respond

Section 143(1) Intimation: What It Means and How to Respond#

Once your Income Tax Return is processed by the Centralised Processing Centre (CPC), you receive an intimation under Section 143(1) by email and on the e-filing portal. It is not a notice in the adversarial sense — it is a computer-generated statement comparing what you reported in your ITR against what the department's own systems computed, based on your return and third-party data (Form 26AS, AIS, TDS records).

What the Intimation Contains#

The intimation is laid out as a two-column comparison:

• Column A — the figures you reported in your return (income, deductions, tax paid).
• Column B — the figures as computed by the CPC after processing.

Below the comparison, it shows one of three outcomes:

1. No demand, no refund — your return matches the department's computation exactly. No further action needed.
2. Refund due — CPC's computation shows tax paid in excess of your final liability. The refund is credited directly to your bank account (the one validated on the e-filing portal) via NEFT/RTGS.
3. Demand raised — CPC's computation shows additional tax payable, usually because of a mismatch (a deduction claimed but not reflected in AIS, TDS credit claimed but not matching Form 26AS, or an arithmetic error).

The 9-Month Deadline#

Under the proviso to Section 143(1), the intimation must be sent before the expiry of 9 months from the end of the financial year in which the return is filed. For a return filed in FY 2025-26, CPC has until 31 December 2026 to send the intimation. If no intimation is received within this window, the return is treated as processed as filed (the acknowledgment itself is deemed the intimation) — but in practice, checking status directly on the portal is more reliable than assuming this by default.

If There's a Demand or a Mismatch#

If Column B doesn't match what you filed:

1. Check the reason first. The most common causes are: TDS claimed in the ITR not matching Form 26AS/AIS, a deduction disallowed because supporting proof wasn't reflected in the third-party data CPC has, or a carry-forward loss not matching prior-year records.
2. If you agree with the demand: Pay it within 30 days of the intimation date to avoid interest under Section 220(2). Payment can be made directly through the e-filing portal against the demand.
3. If you disagree: You can file a rectification request under Section 154 on the e-filing portal (for apparent mistakes like a TDS mismatch that's actually correct on your side), rather than an appeal — Section 154 rectification is the right first step for most 143(1) discrepancies, since they're usually processing-level mismatches, not disputed questions of law.
4. Response window: Responding within 30 days keeps the demand from being treated as final and prevents automatic adjustment against future refunds.

Intimation vs. Notice — Don't Confuse the Two#

A 143(1) intimation is routine and generated for every processed return. A notice under Section 143(2) (scrutiny) or Section 148 (reassessment) is a separate, more serious proceeding that requires active engagement and is not sent to every filer. Don't assume a 143(1) intimation showing "no demand, no refund" means your return is now beyond question — CPC can still select a return for scrutiny separately, within the applicable time limits.

Key Takeaways#

• 143(1) is a computer-generated comparison, not an audit finding — most mismatches trace back to AIS/26AS not matching what you claimed.
• CPC has 9 months from the end of the filing financial year to send it.
• A demand should be paid within 30 days, or corrected via a Section 154 rectification request if you believe it's wrong.
• It is distinct from scrutiny notices under Section 143(2) or reassessment under Section 148.
