Receiving an income tax notice is common and usually not a cause for panic — but it must be answered on time. Notices range from a routine intimation after processing to a scrutiny or reassessment notice.

This guide explains the common notice types and how to respond.

What is Income Tax Notices?

Notices are issued electronically and appear on the e-filing portal. Each cites a section that tells you why it was issued and what response is expected.

Ignoring a notice can lead to best-judgment assessment, penalties and interest.

Step-by-step process

  1. Read carefully. Identify the section, the assessment year and the deadline to respond.
  2. Gather documents. Collect the records the notice asks for.
  3. Respond on the portal. Submit your reply and documents through the e-proceedings/response facility.
  4. Seek help if needed. For scrutiny (143(2)) or reassessment (148), consider professional assistance.
