Got a Tax Notice? Here's Exactly How to Respond (Step-by-Step)

Mar 31, 2026·6 min read

Don't panic. Most tax notices are routine. 143(1) is just a processing acknowledgment. 139(9) means a fixable error. Even 143(2) scrutiny is manageable if you have your documents.

Section 143(1) — Intimation

This is the most common notice. After CPC processes your return, it sends a 143(1) intimation showing its computation. If the tax computed by CPC matches your filing, no action needed. If there's a difference, CPC will show adjustments made. Common reasons: TDS mismatch with Form 26AS, disallowed deductions, or arithmetic errors.

Section 139(9) — Defective Return

This means your return has errors that need fixing. You get 15 days to respond (extendable to 30 days). Common defects: missing Schedule FA (foreign assets), incomplete Schedule CG (capital gains), balance sheet not attached for ITR-3/5, or incorrect form selection.

  1. Log in to the e-filing portal
  2. Go to 'Pending Actions' → 'Response to Defective Return'
  3. Review the specific defect mentioned
  4. Correct the return and submit the revised response
  5. E-verify the corrected return

Section 143(2) — Scrutiny

This is a detailed examination of your return. The assessing officer wants to verify specific claims. You'll receive a questionnaire listing documents to submit. Stay calm, respond within the deadline, and submit only what's asked for. Consider engaging a CA if the amounts involved are significant.

General Response Tips

  • Always respond before the deadline — non-response escalates everything
  • Keep all supporting documents: Form 16, bank statements, investment proofs, rent receipts
  • Match your AIS/TIS data with your filed return before responding
  • If the demand is incorrect, file a response online with supporting evidence
  • For scrutiny or reassessment, consider professional help
