The golden rule: never ignore a notice

Ignoring an income tax notice can lead to penalties, withheld refunds, or worse. The good news: responding is now a fully digital, faceless process, so you do not visit any tax office.

First, identify the notice

SectionWhat it means
143(1)Intimation: processing result or math adjustment
139(9)Defective return: fix and resubmit
143(2)Scrutiny: detailed review of your return
148Income escaping assessment: suspected unreported income
245Refund being adjusted against an old demand

Most notices are time-bound: a 139(9) typically allows 15 days and a 143(1) demand 30 days to respond (Source: Income Tax Act). Always check the deadline printed on the notice.

Reply step by step (portal path)

  1. Log in at incometax.gov.in.
  2. Go to Pending Actions > e-Proceedings.
  3. Click the notice you want to answer.
  4. Agree or disagree as asked, and upload clean, clearly named PDFs (rent receipts, bank statements, TDS certificates).
  5. Submit and save the acknowledgement.

What you should do

Read the section first, note the deadline, and keep responses short, factual, and backed by documents.

Common mistake

Treating every notice as a scrutiny. A 143(1) about a small math difference is routine; a 143(2) or 148 is serious and usually deserves a Chartered Accountant.
