How to Respond to an Income Tax Notice: A Complete Guide
Receiving a notice from the Income Tax Department is one of the most anxiety-inducing experiences for any taxpayer — individual or business. The instinct is often to ignore it, hoping it will go away. It will not. Ignoring an income tax notice is one of the worst things you can do, and it almost always makes the situation significantly worse.
The good news: most income tax notices are routine, and the majority can be resolved without any additional tax liability if you respond correctly and on time.
This guide explains every major type of income tax notice, what triggers each one, and exactly how to respond.
Why the Income Tax Department Sends Notices
The Income Tax Department issues notices for a wide range of reasons — from simple requests for additional information to formal assessments and scrutiny proceedings. The most common triggers include:
- Mismatch between ITR and Form 26AS / AIS / TIS — income reported in your return does not match what third parties have reported to the department
- High-value transactions — large cash deposits, property purchases, or investments that appear inconsistent with declared income
- Non-filing of ITR — you had taxable income but did not file a return
- Defective return — your ITR was filed but has errors or missing information
- Random scrutiny — a small percentage of returns are selected for detailed scrutiny each year
- Specific intelligence — the department has information suggesting undisclosed income
Understanding which type of notice you have received is the first and most important step.
The Major Types of Income Tax Notices
1. Notice under Section 139(9) — Defective Return
What it means: Your ITR has been identified as defective — it may have missing information, incorrect details, or inconsistencies that make it incomplete.
Common reasons:
- Tax payable but not paid before filing
- Missing schedules or incomplete information
- Mismatch in personal details (PAN, name, address)
- Wrong ITR form selected for your income type
How to respond: You have 15 days from the date of the notice (extendable on request) to file a revised return correcting the defect. Log in to the Income Tax e-filing portal, go to e-Proceedings, and submit your response with the corrected return.
Consequence of non-response: The return is treated as if it was never filed — meaning you lose the benefit of filing and may be treated as a non-filer.
2. Notice under Section 143(1) — Intimation
What it means: This is not technically a "notice" — it is an intimation sent after the department processes your ITR. It shows whether your return has been accepted as filed, or whether there is a demand or refund.
Three outcomes:
- No demand, no refund — your return is accepted as filed
- Demand — the department has computed a higher tax liability than you declared
- Refund — you are entitled to a refund
How to respond: If there is a demand, you have 30 days to either agree and pay, or disagree and file a rectification request under Section 154 if you believe the demand is incorrect. Log in to the portal, go to Pending Actions → Response to Outstanding Demand.
Important: A 143(1) intimation is generated automatically by the CPC (Centralised Processing Centre) — it does not mean your return has been selected for scrutiny.
3. Notice under Section 143(2) — Scrutiny Notice
What it means: Your return has been selected for detailed scrutiny. The department wants to verify the income, deductions, and claims you have made.
This is the most serious routine notice. It initiates formal assessment proceedings.
Time limit: The department must issue a 143(2) notice within 3 months from the end of the financial year in which the return was filed. A notice issued after this period is invalid.
How to respond: You must appear before the Assessing Officer (AO) — either in person or through an authorised representative (CA or advocate) — and submit the documents and explanations requested. The AO will issue a questionnaire specifying what is required.
Documents typically requested:
- Bank statements for the relevant year
- Books of accounts (for businesses)
- Investment proofs and purchase/sale documents
- Loan agreements and repayment records
- Evidence for deductions claimed (80C, 80D, HRA, etc.)
Consequence of non-response: The AO can complete a best judgement assessment under Section 144 — estimating your income based on available information, which almost always results in a higher tax demand.
4. Notice under Section 148 — Income Escaped Assessment
What it means: The department believes that income chargeable to tax has "escaped assessment" — meaning it was not declared in your return, or your return was not filed at all.
Time limits for issuing this notice:
- Within 3 years from the end of the relevant assessment year — for cases where escaped income is up to ₹50 lakh
- Within 10 years — for cases where escaped income exceeds ₹50 lakh (with prior approval of the Principal Chief Commissioner)
How to respond: You must file a return of income within 3 months of receiving the notice (or the time specified in the notice). After filing, the AO will conduct an assessment.
Important: Before issuing a 148 notice, the department must now issue a 148A notice — giving you an opportunity to explain why reassessment should not be initiated. This is a critical safeguard introduced by the Finance Act 2021.
5. Notice under Section 148A — Show Cause Before Reassessment
What it means: Before reopening your assessment under Section 148, the AO must give you an opportunity to be heard. The 148A notice asks you to explain why reassessment should not be initiated.
How to respond: You have 7 days (extendable to 30 days) to submit your response. This is your opportunity to demonstrate that the information the department has is incorrect, already disclosed, or does not constitute escaped income.
This is a critical stage — a well-crafted response here can prevent reassessment proceedings entirely.
6. Notice under Section 156 — Notice of Demand
What it means: After an assessment is completed (under 143(3), 144, or 147), if there is a tax demand, the department issues a formal demand notice under Section 156.
How to respond: You must pay the demand within 30 days. If you disagree with the demand, you can file an appeal before the Commissioner of Income Tax (Appeals) — CIT(A) — within 30 days of receiving the demand.
Important: Even if you are filing an appeal, it is advisable to pay at least 20% of the disputed demand to avoid coercive recovery action.
7. Notice under Section 131 — Summons
What it means: The AO has summoned you to appear in person and/or produce specific documents or books of accounts.
How to respond: You must comply with the summons. Failure to appear or produce documents without reasonable cause is an offence under the Income Tax Act.
8. Notice under Section 133(6) — Information Request
What it means: The department is seeking information about a specific transaction — often sent to banks, financial institutions, or third parties, but sometimes to the taxpayer directly.
How to respond: Provide the information requested within the specified time. This is often a preliminary step before a more formal notice.
Step-by-Step: What to Do When You Receive a Notice
Step 1: Do Not Panic — Read It Carefully
Identify the section under which the notice is issued. This determines the nature of the proceedings and your response obligations.
Step 2: Verify Authenticity
All genuine income tax notices are issued through the e-filing portal and have a Document Identification Number (DIN). Verify the notice at incometaxindiaefiling.gov.in before responding.
Step 3: Note the Deadline
Every notice has a response deadline. Missing it can have serious consequences — from best judgement assessments to penalties. Mark the deadline immediately.
Step 4: Gather Your Documents
Identify what the notice is asking for and start gathering the relevant documents — bank statements, investment proofs, books of accounts, contracts, etc.
Step 5: Consult a CA or Tax Advisor
For anything beyond a simple 143(1) intimation, engage a Chartered Accountant or tax advisor. Scrutiny proceedings, reassessment notices, and demand notices require professional handling.
Step 6: Respond Through the Portal
All responses to income tax notices must be submitted through the Income Tax e-filing portal under e-Proceedings. Do not send physical responses unless specifically instructed.
Common Mistakes to Avoid
Ignoring the notice — The single biggest mistake. The department will proceed ex-parte (without your participation), almost always resulting in a higher demand.
Responding without professional advice — For scrutiny and reassessment notices, an incorrect or incomplete response can create more problems than it solves.
Missing the deadline — Even a day's delay can require you to apply for condonation of delay, adding complexity to the proceedings.
Not keeping copies — Always keep copies of every document you submit and every response you file.
Paying a demand without verifying it — Many 143(1) demands are incorrect. Verify before paying, and file a rectification if the demand is wrong.
Penalties for Non-Compliance
| Offence | Penalty |
|---|---|
| Failure to respond to 143(2) scrutiny notice | Best judgement assessment under Section 144 |
| Failure to comply with summons under Section 131 | Fine up to ₹10,000 per default |
| Concealment of income | 100%–300% of tax evaded under Section 271(1)(c) |
| Non-filing of return despite notice | Prosecution under Section 276CC |
