Section 143(1)(a) Intimation & Notice Response | Savlana Init

Income Tax · Section 143(1)(a)

Section 143(1)(a) Notice — respond accurately, reduce the demand.

A Section 143(1)(a) intimation can result in a tax demand, an additional refund, or a simple confirmation — and the response you give within 30 days determines which of these you get.

Section 143(1)(a) of the Income Tax Act, 1961 provides the mechanism by which the Income Tax Department processes filed returns and issues an intimation proposing adjustments. These adjustments are made by the Centralised Processing Centre (CPC) on the basis of apparent arithmetic errors, incorrect claims made against the return on its face, or differences between the income declared and the TDS data available in Form 26AS and the Annual Information Statement.

The intimation under Section 143(1)(a) is a show-cause notice — it proposes an adjustment and calls for a response within 30 days. If no response is given, the CPC finalises the intimation as an assessment under Section 143(1) and issues a demand or a reduced refund accordingly. If the response is accepted, the intimation is revised in the taxpayer’s favour.

Common adjustments proposed under Section 143(1)(a) include disallowance of loss where the return of income was not filed before the due date; disallowance of expenditure indicated in the audit report but not claimed in the return; addition of income appearing in Form 26AS or AIS but not reflected in the return; and arithmetic corrections to the tax computation. Each requires a different response, and the quality of that response determines the outcome.

Frequently Asked Questions

Common adjustments include: addition of income in AIS or Form 26AS not reflected in the return; disallowance of loss where the return was filed after the due date; disallowance of deductions claimed without the required audit report; and arithmetic errors in the tax computation.

The taxpayer has 30 days from the date of the intimation to submit a response objecting to the proposed adjustments. If no response is submitted within 30 days, the adjustment is finalised and an intimation under Section 143(1) is issued with the resulting demand.

Yes. The online response mechanism allows you to accept or reject each proposed adjustment individually. You can accept adjustments that are factually correct and object to those that are erroneous, providing supporting documents for each objection.

The CPC reviews the response and either accepts the objections and issues a revised intimation, or confirms the proposed adjustments. If confirmed and you believe the adjustment is wrong, the next step is to file a rectification under Section 154 or an appeal before the CIT(A).

There is no specific penalty solely for not responding. However, the consequence is that the adjustment is finalised, a demand may be raised, and you lose the opportunity to object at the intimation stage — forcing a costlier and more time-consuming rectification or appeal process.

Yes — if the intimation reveals that the return has a genuine omission or incorrect claim, and the assessment year is still within the revised return window, you can file a revised return under Section 139(5). The revised return can address the underlying issue before the intimation is finalised.

30 days to respond. Don’t let them pass.

We review the intimation, reconcile the data, draft the response, and file it in time — protecting you from incorrect demands and lost refunds.
