Got an Income Tax Notice Under Section 143(1)? It's Not a Raid — Here's How to Read and Reply

A 143(1) intimation is routine — not a raid

Almost every taxpayer receives a Section 143(1) intimation after filing, and most panic unnecessarily. It is not a scrutiny notice or an investigation. It is an automated communication confirming how the Centralised Processing Centre (CPC) has processed your return — comparing what you declared with the tax department's own records. Understanding the three outcomes it can show, and how to respond when it proposes an adjustment, turns a stressful email into a five-minute task.

What the 143(1) actually checks

The CPC processes your return arithmetically and against third-party data: it verifies your computation, your TDS/TCS credits from 26AS, the income reported in your AIS, and any obvious inconsistencies or disallowed claims. It then issues an intimation showing two columns — "as provided by you" and "as computed under 143(1)" — side by side.

The three outcomes

1. No change — the two columns match. The intimation simply confirms your return is accepted as filed. Nothing to do; keep it for your records.
2. Refund determined — the department agrees you overpaid; your refund is confirmed and issued to your pre-validated bank account.
3. Demand or adjustment — the department's computation differs, creating a tax demand (or reducing your refund). This is the only outcome that needs action, and it usually stems from a mismatch — a TDS credit not picked up, income in the AIS you didn't report, or a deduction disallowed for want of proof.

How to respond to a proposed adjustment in 30 days

Before any adjustment is made, the CPC gives you a 30-day window to respond through the e-filing portal's e-proceedings. Read the intimation carefully, identify the exact line that differs, and either agree (and pay the demand) or disagree (and submit your explanation with proof). If a TDS credit was missed, point to the 26AS entry; if income was double-counted in the AIS, attach the reconciliation. Responding within the window is essential — silence is treated as agreement and the adjustment is confirmed.

If you miss the window — rectification under 154

If the 30 days lapse or you spot an error later, you can file a rectification request under Section 154 for a mistake apparent from the record (a mismatched TDS credit, an arithmetic error). For genuine grievances you also retain appeal rights. But responding within the original window is always cleaner and faster.

Why most demands are avoidable

The overwhelming majority of 143(1) demands trace back to a pre-filing data mismatch — exactly what AIS reconciliation prevents. A return that ties cleanly to your AIS and 26AS rarely produces an adjustment. When one does arrive, calm, evidenced, on-time response resolves it.

The bottom line

Don't panic at a 143(1). Identify which of the three outcomes you have, act only if it proposes a demand, respond within 30 days with proof, and use rectification if needed. Better still, reconcile before you file so the intimation simply says "no change".

Pune note

Got a notice in Pune? We respond within the week. Every August and September, Pune taxpayers forward us 143(1) intimations in a panic — and in most cases it is a simple mismatch: a TDS credit the CPC didn't pick up, or AIS income that was double-counted. At RDA Tax Advisory Services, Baner, we read the intimation, isolate the exact line that differs, and draft an evidenced response through the e-filing portal well inside the 30-day window. Where a credit was genuinely missed, we point to your 26AS; where the AIS overstated income, we attach the reconciliation. If the window has lapsed, we file a Section 154 rectification. Most of our Pune clients never see a 143(1) demand in the first place, because we reconcile their AIS before filing — but if one lands in your inbox, bring it to us the same day: Office No. 102, Snehraj Apartment, Baner, Pune 411045, or call +91 77570 45059.
