Income Tax Notices in India — Types, Triggers & How to Respond

Receiving an Income Tax notice triggers anxiety in most taxpayers — but most notices are routine, non-adversarial, and easily resolved with a correct, timely response. Ignoring a notice, however, can convert a simple query into a full assessment, tax demand, penalty, and prosecution. This guide explains the most common income tax notices Indian taxpayers receive, what they mean, and exactly how to respond — so you can approach each with confidence instead of panic.

1. Most Common Income Tax Notices

Section	Notice Type	What It Means	Response Deadline
143(1)	Intimation — not really a notice	Auto-processed result of your ITR — shows tax payable or refund. Not adversarial.	No response needed unless demand raised
143(2)	Scrutiny Notice	Your return is selected for detailed scrutiny — officer will examine your income, deductions, and claims	Must respond within 15 days
148 / 148A	Reassessment Notice	Officer believes income escaped assessment in a past year — proposes to reopen that year's assessment	148A(b): Reply within 7 days; 148: File return within 3 months
139(9)	Defective Return Notice	Your ITR has technical defects — missing schedules, mismatched data, wrong ITR form	15 days to rectify
245	Adjustment of Refund Against Demand	Department wants to adjust your pending refund against an old tax demand	30 days to agree or object
131	Summons / Production of Documents	Officer requires your books, documents, or your personal attendance for examination	As specified in notice
156	Notice of Demand	Tax demand after assessment — amount due must be paid within 30 days	30 days to pay or appeal

2. Notices Due to AIS / 26AS Mismatch — Most Common Today

The Annual Information Statement (AIS) captures almost every financial transaction — property purchases and sales, high-value cash deposits, mutual fund redemptions, share transactions, foreign remittances, interest income, GST turnover, and more. The Income Tax Department cross-references your ITR with your AIS. If a high-value transaction in your AIS is not reflected in your ITR, an automated notice under Section 133(6) or 142(1) is issued asking for explanation.

Common AIS mismatch situations:

• Property purchased or sold — not reported in ITR (capital gains omitted)
• Large cash deposits in bank account not explained by income
• Interest income from FDs not included in ITR
• Share/MF redemptions appearing as income not reported
• GST turnover far exceeding income declared in ITR
• Freelance/professional income received as UPI or bank transfer not reported

3. How to Respond to an Income Tax Notice

• Never ignore: Ignoring a notice leads to ex-parte assessment — the officer decides based on available data alone — always against you
• Read carefully: Understand the section, the specific issue raised, and the deadline
• Gather documents: Bank statements, purchase invoices, sale deeds, Form 26AS, TDS certificates, books of accounts — collect everything relevant
• Prepare a point-by-point written response: Address each issue raised by the officer — supported by documentary evidence
• Submit online: Most responses are submitted on the Income Tax Portal (the official government portal) under "Pending Actions"
• Engage a CA: For 143(2) scrutiny, 148 reassessment, and 131 summons — always engage a CA to represent you

4. What If You Disagree with the Assessment Order?

If the Assessing Officer passes an unfavourable order after scrutiny — adding income or disallowing deductions — you have the right to appeal. The appeal hierarchy is: CIT(Appeals) → ITAT (Income Tax Appellate Tribunal) → High Court → Supreme Court. Time limit for filing appeal before CIT(A) is 30 days from receipt of assessment order. A pre-deposit of 20% of disputed demand is required. Our CA team files and argues appeals before CIT(A) and ITAT.
