ITR-3 Notice from Income Tax Department: Common Reasons and What to Do

Receiving an ITR-3 notice from the Income Tax Department can be confusing, especially if you have already filed your income tax return for AY 2026-27.

An income tax notice does not always mean that you have made a serious mistake or that additional tax is automatically payable. A notice may be issued for several reasons, including TDS mismatch, income discrepancies, missing information, defective return, verification of transactions, tax calculation differences or non-compliance with a particular requirement.

If you have received an ITR-3 notice, the first step is to carefully read the notice, identify the reason, check the response deadline and then submit an appropriate response through the Income Tax e-Filing portal.

In this guide, we explain the common reasons for ITR-3 notices, different types of notices, how to check an income tax notice online and what you should do after receiving one.

What Is an ITR-3 Notice?

An ITR-3 notice is a communication issued by the Income Tax Department in connection with your income tax return or other tax-related information.

The notice may relate to:

• ITR-3 filing
• Income reported in the return
• TDS details
• AIS information
• Form 26AS
• Business income
• Capital gains
• House property income
• Tax calculation
• Deductions
• Refund claim
• Verification of transactions
• Defective return
• Return processing

The exact reason depends on the notice issued by the department.

Therefore, taxpayers should not ignore an ITR-3 notice.

Why Do You Receive an ITR-3 Notice?

There can be several reasons why the Income Tax Department sends a notice after ITR-3 filing.

Some common reasons include:

1. TDS mismatch
2. Difference between AIS and ITR
3. Form 26AS mismatch
4. Income mismatch
5. Business turnover discrepancy
6. Capital gains mismatch
7. Incorrect deductions
8. Incorrect tax calculation
9. Defective return
10. Verification of refund claim
11. Non-verification or compliance requirement
12. Additional information required by the department

Let's understand these reasons in detail.

1. TDS Mismatch

One of the most common reasons for an income tax notice is a difference in TDS information.

For example, suppose your ITR-3 claims:

TDS Credit = ₹1,00,000

But the tax department's records show:

TDS Available = ₹80,000

This may result in a discrepancy during processing.

Before filing ITR-3, taxpayers should reconcile their TDS with:

• Form 26AS
• AIS
• Form 16
• TDS certificates
• Other applicable TDS documents

If there is a genuine difference, identify the reason before responding to the notice.

2. Difference Between AIS and ITR-3

The Annual Information Statement (AIS) contains financial information reported to the Income Tax Department.

It may include information relating to:

• Salary
• Interest
• Dividend
• Securities transactions
• Mutual funds
• Property transactions
• TDS
• Other reported financial transactions

If information appearing in AIS does not match the income reported in your ITR-3, the department may seek clarification.

For example:

AIS shows interest income = ₹75,000

but

ITR-3 shows interest income = ₹25,000

The taxpayer should review the underlying transaction and determine the correct amount before responding.

An AIS entry should not automatically be treated as taxable income without understanding what the transaction represents.

3. Form 26AS Mismatch

Form 26AS is another important tax record that should be checked before filing ITR-3.

A mismatch can occur when:

• TDS is incorrectly reported
• TDS credit is claimed incorrectly
• PAN details are incorrect
• TDS is reported under a different section
• Tax deducted by a deductor has not yet been reflected

If you receive an ITR-3 notice related to TDS, compare your return with Form 26AS and the relevant TDS certificates.

4. Business Income or Turnover Difference

Taxpayers filing ITR-3 often have business or professional income.

A notice may be triggered if there is a difference between the business information reported in the ITR and information available with the department.

For example:

• GST turnover differs from ITR turnover
• Business receipts differ from bank credits
• TDS receipts do not match reported business receipts
• Turnover reported in different records is inconsistent
• Business expenses appear unusual or unsupported

This is why business owners should maintain proper books and reconcile their financial information before filing ITR-3.

5. Capital Gains Mismatch

Taxpayers having income from shares, mutual funds, securities or property may have capital gains.

A notice may arise if capital-gain information reported in ITR-3 differs from information available with the department.

For example:

• Share transactions not reported
• Mutual fund redemption omitted
• Incorrect purchase cost
• Incorrect sale consideration
• Capital loss incorrectly reported
• STCG/LTCG classification issue
• Difference between broker statement and ITR

Before filing ITR-3, reconcile your capital gains with your broker or mutual-fund statement.

6. House Property or Rental Income Difference

If you have rental income, the department may compare the information reported in ITR-3 with other available records.

Potential issues may include:

• Rental income not reported
• Incorrect annual rent
• Incorrect municipal tax claim
• Incorrect home-loan interest
• House property loss claimed incorrectly
• Property information mismatch

Rental income should be properly calculated under the Income from House Property head.

7. Incorrect Deductions

An ITR-3 notice may also be related to deductions claimed in the return.

Examples include:

• Section 80C
• Section 80D
• Section 80G
• Other eligible deductions

A taxpayer should claim only deductions for which they are eligible and maintain supporting documents.

If the department asks for clarification, provide the relevant information or documents as required.

8. Incorrect Tax Calculation

Sometimes a notice can arise because the tax calculation in the filed return does not match the department's computation.

Possible reasons include:

• Incorrect tax rate
• Incorrect income computation
• Incorrect TDS credit
• Incorrect advance tax
• Incorrect self-assessment tax
• Incorrect surcharge or cess
• Incorrect treatment of losses

Read the computation carefully before responding.

9. Defective ITR-3

A return can be treated as defective when required information is missing or the return has not been completed correctly.

For example, a defect may relate to:

• Missing mandatory information
• Incorrect schedule details
• Incomplete business information
• Required financial details not properly furnished
• Incorrect reporting in a particular schedule

If you receive a notice regarding a defective return, the notice generally explains what needs to be corrected.

Do not ignore a defective-return communication because failure to respond within the specified period can have consequences.

10. Refund Verification

A taxpayer may also receive communication regarding a refund claim.

This can happen when the department requires additional verification before processing or releasing a refund.

For example:

• Large refund claimed
• TDS credit is high
• Income and TDS do not match
• Refund is inconsistent with available information
• Additional verification is required

If you receive a refund-related communication, carefully check the communication and respond through the official e-Filing portal.

11. High-Value Transactions

The Income Tax Department receives information about various financial transactions from reporting entities.

Examples may include:

• Purchase or sale of property
• Securities transactions
• Mutual fund transactions
• Large bank transactions
• Interest income
• Other reportable transactions

If a significant transaction is not reflected appropriately in the ITR-3, the department may seek clarification.

This does not necessarily mean the transaction itself is taxable; the taxpayer should examine the nature of the transaction and respond appropriately.

12. Non-Compliance or Verification Requirement

Some communications may simply require the taxpayer to provide information, complete a verification or take a specific action.

Therefore, always check:

• Notice number
• Section mentioned
• Assessment year
• Date of notice
• Response deadline
• Required action
