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

Receiving a 143(1) intimation after filing your ITR is common for traders. It is a computer-processed comparison of your return against third-party data. Here is what it usually says, what traders most commonly get flagged for, and how to respond.

Note: This is general information, not tax advice, and tax rules change. Verify the current figures against the Income Tax Act, the relevant Finance Act and ICAI guidance, and confirm your own position with a qualified Chartered Accountant.

What Section 143(1) is

After you file your ITR, the CPC (Centralized Processing Centre) processes it. As part of this processing, it checks the return against data from third parties: your Form 26AS (TDS), the AIS (Annual Information Statement) and the TIS (Taxpayer Information Summary). Where it finds a discrepancy (income reported on AIS but not on the return, a mismatch in TDS credit, a mathematical error), it sends a 143(1) intimation noting the adjustment it proposes to make.

A 143(1) intimation is not a notice under 143(2) (scrutiny) or 148 (reassessment). It is a routine processing communication. Most are resolved in a week or two. Do not panic: read it carefully, check the figures, and decide whether to agree or file a rectification.

What triggers a 143(1) for F&O traders

F&O traders see 143(1) intimations more often than pure equity investors because:

  • AIS vs ITR mismatch on turnover: The AIS may show a gross transaction volume from broker data that differs from the ICAI turnover on the return. The department may flag this as an income mismatch.
  • F&O loss claimed without audit: If your return claims an F&O loss and the department determines that a tax audit was required (perhaps under 44AB(e)), it may disallow the loss.
  • TDS credit mismatch: TDS deducted by the exchange (1% on VDA sales or other sources) may not match what the return claims.
  • Unreported income from AIS: Dividend, interest, or other items on AIS that the return did not include.

How to read the intimation

Download the intimation from the income-tax portal (e-Filing โ†’ View Filed Returns โ†’ Action โ†’ View Intimation u/s 143(1)). It shows a side-by-side table: what you declared on the return, what the CPC computed, and the adjustment. Read the adjustment reasons carefully. They use standardized codes; the most common for traders are A (income addition) and B (disallowance).

Responding to a demand under 143(1)

If the 143(1) shows a tax demand:

  • If you agree: Pay the demand online under Challan 280 within 30 days. The demand self-closes once payment is reflected.
  • If you disagree: File a rectification under Section 154 on the portal. Explain the discrepancy, attach supporting documents (broker P&L, Form 26AS, AIS). The CPC reviews and may revise the demand.
  • If the issue is complex: File a rectification and simultaneously get your CA involved. A complex 143(1), such as one disputing an F&O loss or turnover methodology, may escalate to the assessing officer if the rectification route does not resolve it.
Interest under Section 234B and 234C continues to accrue on unpaid demand. If you plan to dispute the 143(1) but the amount is small, consider paying under protest rather than waiting. Your CA can advise on whether to pay now and reclaim via rectification or appeal.

Common trader mistakes that lead to 143(1)

The easiest way to avoid 143(1) adjustments is to make sure your ITR reflects everything on your AIS. Use the AIS reconciliation guide to cross-check your return before filing. If you find a discrepancy after filing, consider filing a revised return before the deadline (December 31 of the assessment year). See belated and revised returns for traders.

Frequently asked questions

Is a 143(1) intimation the same as a tax notice?

No. A 143(1) intimation is a computer-generated communication, not a scrutiny notice. It is sent after the CPC processes your ITR and notes a mathematical discrepancy, missing income, or a disallowance. It does not mean the department suspects tax evasion. Most 143(1) intimations are resolved by agreeing with the adjustment or filing a rectification.

What does a 143(1) intimation typically say for F&O traders?

Common adjustments for traders include: income addition from AIS (broker-reported TDS or transaction data the return did not disclose), disallowance of a loss claimed without the required audit, turnover mismatch between AIS and the return, or TDS credit claimed but not matched against TDS records.

How long do I have to respond?

A 143(1) intimation is not a formal demand for response unless it results in a tax demand. If it shows a refund or no change, no action is needed. If it shows a demand, you have 30 days to pay, or you can file a rectification (Section 154) or appeal if you disagree.

Can I ignore a 143(1) if I agree with the adjustment?

If you agree with the 143(1) adjustment and the demand is correct, you should pay the demand within 30 days to avoid interest. If you receive a refund intimation with a correct amount, no action is needed, it will be credited. Ignoring an outstanding demand attracts interest and recovery proceedings.
