How to Respond to an Income Tax Notice in India: A Complete Step-by-Step Guide (2026)
Received an Income Tax Notice? Don’t Panic.
Receiving an Income Tax Notice can be stressful, especially if it’s your first time. Many taxpayers immediately assume they have done something wrong or that legal action is about to begin. In reality, this is rarely the case.
The Income Tax Department issues notices for several reasons. Some notices simply request additional information, while others highlight mismatches between the information reported in your Income Tax Return (ITR) and the records available with the department. In many situations, responding correctly and within the specified deadline resolves the matter without further proceedings.
Whether you’re a salaried professional, business owner, startup founder, freelancer, or company director, understanding why you received an Income Tax Notice and how to respond appropriately is essential to avoiding unnecessary penalties, interest, or future complications.
In this guide, we’ll explain:
- Why Income Tax Notices are issued
- Different types of notices under the Income Tax Act
- How to verify whether the notice is genuine
- The documents you’ll need
- The step-by-step process for submitting a response online
- Common mistakes to avoid
- When it’s advisable to consult a Chartered Accountant

How Do You Respond to an Income Tax Notice?
If you’ve received an Income Tax Notice, begin by identifying the section under which it has been issued and carefully read the reason mentioned in the notice. Verify its authenticity through the Income Tax e-Filing Portal, gather all relevant documents, prepare an accurate response, and submit it before the deadline. If the notice involves scrutiny, reassessment, or complex tax issues, consult an experienced Chartered Accountant to ensure the response is complete and compliant.
What Is an Income Tax Notice?
An Income Tax Notice is an official communication issued by the Income Tax Department requesting clarification, additional information, correction of errors, payment of outstanding tax, or participation in an assessment proceeding.
Contrary to popular belief, receiving a notice does not automatically mean that you have violated tax laws or committed tax evasion.
Many notices are generated automatically due to:
- Information mismatches
- Missing details
- High-value financial transactions
- Routine verification processes
- Incorrect return filing
- Delayed responses
- Defective returns
In many cases, responding accurately within the prescribed timeline is all that’s required to close the matter.
Why Does the Income Tax Department Send Notices?
The Income Tax Department uses data from multiple sources, including:
- Banks
- Employers
- Mutual fund companies
- Stock exchanges
- Property registration authorities
- GST records
- Annual Information Statement (AIS)
- Form 26AS
- Financial institutions
If discrepancies are detected between these records and your Income Tax Return, a notice may be issued requesting clarification.
Common Reasons for Receiving an Income Tax Notice
| Reason | Explanation |
| Income mismatch | Income reported differs from AIS or Form 26AS |
| TDS mismatch | TDS claimed does not match department records |
| High-value transactions | Property purchases, investments, or large deposits require explanation |
| Defective return | Missing or incorrect information in the ITR |
| Failure to file ITR | Return not filed within the prescribed timeline |
| Incorrect deductions | Excess deductions or exemptions claimed |
| Capital gains not reported | Sale of shares, mutual funds, or property omitted |
| Scrutiny selection | Return selected for detailed examination |
Expert Tip: Receiving a notice because of an information mismatch is common and often straightforward to resolve with proper documentation.
Is Every Income Tax Notice Serious?
No. One of the biggest misconceptions is that every notice indicates fraud or tax evasion. Different notices serve different purposes.
Some notices simply ask you to:
- Correct a clerical error
- Verify information
- Submit supporting documents
- Confirm a tax credit
- Explain a financial transaction
Others, such as scrutiny or reassessment notices, require more detailed responses and may involve additional proceedings. The key is to understand the section under which the notice has been issued.
Different Types of Income Tax Notices Explained
Understanding the section number helps you determine the purpose of the notice and the action required.
| Section | Purpose | What You Should Do |
| 139(9) | Defective Return | Correct errors and submit a revised response |
| 142(1) | Inquiry Before Assessment | Provide requested documents and explanations |
| 143(1) | Intimation | Review tax computation and verify any discrepancies |
| 143(2) | Scrutiny Assessment | Prepare detailed financial records and supporting evidence |
| 148 | Income Escaping Assessment | Respond with complete documentation and professional assistance |
| 156 | Demand Notice | Review the demand, pay if correct, or file an objection if applicable |
Section 139(9): Defective Return
A notice under Section 139(9) indicates that your Income Tax Return contains errors, omissions, or incomplete information that prevent it from being processed.
Common reasons include:
- Missing financial statements
- Incorrect schedules
- Mismatched PAN details
- Missing audit reports
- Incomplete disclosures
In most cases, you’ll need to rectify the return within the time specified in the notice.
Section 142(1): Inquiry Notice
A notice under Section 142(1) requests additional information or supporting documents before completing the assessment.
You may be asked to provide:
- Bank statements
- Books of accounts
- Investment proofs
- Invoices
- GST records
- Financial statements
Responding accurately and on time is essential to avoid further proceedings.
Section 143(1): Intimation Notice
This is one of the most common notices. It is issued after the Income Tax Department processes your return.
The department compares:
- Income declared
- TDS
- Tax paid
- Deductions claimed
with its own records. If differences are identified, the intimation will explain them. Sometimes no action is required, while in other cases you may need to respond or pay additional tax.
Section 143(2): Scrutiny Notice
This notice means your return has been selected for detailed examination.
The objective is to verify:
- Income
- Expenses
- Deductions
- Investments
- Business transactions
- Tax computations
Scrutiny assessments require organized documentation and professional representation. Businesses often engage experienced Chartered Accountants at this stage to ensure proper compliance and representation.
Section 148: Income Escaping Assessment
A notice under Section 148 is issued when the department believes certain income has escaped assessment. These matters are generally more complex and should be handled carefully with appropriate professional advice.
Section 156: Demand Notice
This notice informs you that additional tax, interest, or penalties are payable.
Before making payment, carefully verify:
- Tax calculations
- TDS credits
- Challans
- Previous tax payments
If you disagree with the demand, you may be able to file an online response with supporting evidence.
How to Verify Whether Your Income Tax Notice Is Genuine
Before preparing your response, the first step is to ensure that the notice you have received is authentic. Fraudulent emails and fake notices impersonating the Income Tax Department have become increasingly common, making verification an essential part of the process.
An authentic Income Tax Notice will always include important details such as:
- Document Identification Number (DIN)
- PAN of the taxpayer
- Assessment Year (AY)
- Notice section (for example, Section 143(1) or Section 142(1))
- Date of issue
- Response due date
- Details of the issuing Income Tax authority
If you receive a notice through email or physical post, do not immediately click on links or share personal information. Instead, verify the notice by logging into the official Income Tax e-Filing Portal.
Expert Tip: Always rely on the official Income Tax e-Filing Portal rather than links received through emails or messages from unknown sources.
Step-by-Step Process to Respond to an Income Tax Notice Online
Most Income Tax Notices can now be responded to online through the Income Tax e-Filing Portal. The process is straightforward if you understand the notice and have all supporting documents ready.

- Information requested
- Deadline for response

Each notice is different, and the response depends entirely on the section under which it has been issued.
Step 2: Identify the Type of Notice
The notice section tells you what action is expected.
For example:
| Notice | Action Required |

| 142(1) | Submit documents and explanations |
| 143(2) | Prepare for the scrutiny assessment |
| 148 | Respond regarding escaped income |

Understanding the notice correctly prevents unnecessary errors during submission.

Real-Life Examples of Common Income Tax Notices
Understanding how Income Tax Notices work in real situations helps taxpayers respond more confidently. Below are some practical examples that businesses and individuals commonly face.
Example 1: Mismatch Between Income Reported and AIS
Situation
A salaried professional filed an Income Tax Return declaring salary income but forgot to include interest earned from fixed deposits. The Income Tax Department’s Annual Information Statement (AIS) reflected the interest income, resulting in a mismatch.
Notice Received
Section 143(1)
Resolution
The taxpayer reviewed Form 26AS and AIS, accepted the mismatch, and filed a revised return.
Learning
Always compare your Income Tax Return with:
- AIS
- Form 26AS
- Form 16
- Bank Interest Statements
before filing.
Example 2: GST Turnover Doesn’t Match Income Tax Return
Situation
A business reported sales of ₹2.8 crore in GST returns but declared only ₹2.45 crore turnover in the Income Tax Return. The mismatch triggered an inquiry.
Notice Received
Section 142(1) Notice
Resolution
The business submitted:
- Books of Accounts
- GST Returns
- Sales Register
- Reconciliation Statement
The matter was resolved after explaining the timing differences.
Learning
Businesses should regularly reconcile:
- GST Returns
- Financial Statements
- Income Tax Returns
to avoid unnecessary notices.
Example 3: Property Sale Not Reported
Situation
An individual sold a residential property but assumed that because the money was reinvested, reporting was unnecessary. The transaction appeared in government records.
Notice Received
Section 148 Notice
Resolution
A Chartered Accountant prepared:
- Capital Gain Computation
- Purchase & Sale Documents
- Exemption calculations
- Supporting evidence
The taxpayer responded successfully.
Learning
Even exempt transactions should generally be disclosed correctly in the Income Tax Return where applicable.
Example 4: Scrutiny Assessment for Business Expenses
Situation
A company claimed substantial marketing expenses. The Assessing Officer requested supporting documentation.
Notice Received
Section 143(2)
Resolution
The company submitted:
- Vendor invoices
- Bank statements
- Agreements
- GST invoices
The assessment concluded successfully.
Learning
Maintain organized documentation for every significant business expense.
How to Avoid Receiving Income Tax Notices
Not every notice can be avoided, but many arise because of preventable mistakes. Following good compliance practices significantly reduces the likelihood of receiving unnecessary notices.
File Your Income Tax Return on Time
Late filing increases the risk of penalties, interest, and compliance issues. Filing within the due date also provides adequate time to correct any genuine mistakes.
Verify AIS and Form 26AS Before Filing
Many notices result from differences between:
- Income Tax Return
- Annual Information Statement (AIS)
- Form 26AS
- Tax Deducted at Source (TDS) records
Reviewing these documents before filing helps identify discrepancies early.
Report Every Source of Income
Commonly overlooked income includes:
- Savings account interest
- Fixed deposit interest
- Capital gains
- Rental income
- Dividend income
- Foreign income (where applicable)
Complete disclosure reduces the chances of mismatch notices.
Maintain Proper Financial Records
Businesses should preserve:
- Books of accounts
- Purchase invoices
- Sales invoices
- Bank statements
- GST records
- Payroll records
- Investment proofs
Proper documentation makes responding to notices significantly easier.
Reconcile GST and Income Tax Data
For businesses registered under GST, turnover reported in GST returns should align with financial statements and Income Tax Returns. Any genuine differences should be documented with reconciliation statements.
Seek Professional Review Before Filing
A professional review often identifies errors before returns are submitted, reducing the likelihood of notices and future disputes.
