In many cases, the Income Tax Department sends notices to request additional information, point out a mismatch, inform the taxpayer about a refund or tax demand, or ask for corrections in the filed return.
Different notices are issued under different sections of the Income Tax Act. Understanding the purpose of each notice can help taxpayers take the right action within the specified deadline.
1. Income Tax Notice Under Section 142(1)
A notice under Section 142(1) may be issued when the Income Tax Department requires additional information, documents or clarification related to a taxpayer’s income or tax return.
It can also be issued to a person who has not filed an Income Tax Return despite being required to do so.
The department may ask for details related to income, deductions, exemptions, investments or other financial information. Taxpayers should carefully review the notice and submit the requested information within the given time.
2. Income Tax Notice Under Section 133(6)
A notice under Section 133(6) is generally issued when the department requires information about a person’s financial transactions or income.
The department may use this provision to verify information received from banks, employers, financial institutions or other sources.
A notice may be issued when there is a mismatch between reported income and available financial information. Receiving this notice does not automatically mean that the taxpayer has committed tax evasion, but the requested information should be provided accurately.
3. Income Tax Intimation Under Section 143(1)
Section 143(1) is one of the most common communications received by taxpayers after filing an ITR.
The Income Tax Department processes the return and compares the information submitted by the taxpayer with available records. The intimation may show that:
- The return has been processed without any adjustment.
- A tax refund is due.
- Additional tax is payable.
- Certain adjustments have been made to the return.
In many cases, this is simply an intimation and may not require any action. However, taxpayers should carefully check the details mentioned in the communication.
4. Income Tax Notice Under Section 143(2)
A notice under Section 143(2) is issued when the Income Tax Department selects an Income Tax Return for detailed scrutiny.
The department may request additional documents, explanations or supporting evidence related to income, deductions, exemptions or other claims made in the return.
Receiving a scrutiny notice does not automatically mean that a taxpayer has committed any wrongdoing. It means that the department wants to examine certain details of the return more closely.
The taxpayer should respond within the prescribed time and provide accurate information and supporting documents.
5. Income Tax Notice Under Section 148
A notice under Section 148 may be issued when the Income Tax Department believes that income chargeable to tax may have escaped assessment.
This could involve situations where certain income was not disclosed or where information available with the department indicates that the earlier assessment may require further examination.
Such notices can involve reassessment proceedings and should be handled carefully. Taxpayers may consider consulting a qualified tax professional to understand the notice and the appropriate response.
6. Income Tax Notice Under Section 245
A notice under Section 245 is generally issued when the Income Tax Department proposes to adjust a taxpayer’s refund against an outstanding tax demand from another assessment year.
For example, a taxpayer may be eligible for an income tax refund for the current year but may have an unpaid tax demand from a previous year.
Before adjusting the refund, the department may provide an opportunity to respond. Taxpayers should verify whether the outstanding demand mentioned in the notice is correct and submit a response within the specified period.
7. Income Tax Demand Notice Under Section 156
A notice issued under Section 156 is commonly known as a demand notice.
It is issued when the Income Tax Department determines that a taxpayer has an outstanding amount payable. This amount may include:
- Additional income tax.
- Interest.
- Penalty.
- Other applicable charges.
The notice generally mentions the amount payable and the deadline for payment or response. Taxpayers should verify the demand carefully and take appropriate action within the specified time.
If the demand appears incorrect, the taxpayer may need to respond through the appropriate process instead of simply ignoring the notice.
8. Defective Return Notice Under Section 139(9)
A notice under Section 139(9) is issued when the Income Tax Department considers an ITR to be defective.
This may happen because of missing information, incorrect details, incomplete disclosures or inconsistencies in the return.
The taxpayer is generally given an opportunity to correct the defect and submit the required information within the prescribed time.
If the required corrections are made within the deadline, the return can continue to be treated as valid. Ignoring the notice may result in the return being treated as invalid.
What Should You Do After Receiving an Income Tax Notice?
The first step is to remain calm and carefully read the notice. Check the section under which the notice has been issued and understand what information or action is required.
Taxpayers should verify the notice through the official Income Tax e-Filing portal and avoid responding to suspicious emails or messages.
It is important to keep records such as ITR acknowledgements, Form 16, AIS, TIS, bank statements, investment proofs and other tax-related documents properly organised.
If the notice involves a complex issue, reassessment, scrutiny or a significant tax demand, consulting a qualified Chartered Accountant or tax professional may be helpful.
Why You Should Not Ignore an Income Tax Notice
Ignoring an Income Tax Department notice can create unnecessary complications. A missed deadline may result in additional proceedings, penalties or difficulties in resolving the matter later.
At the same time, receiving a notice does not automatically mean that the taxpayer is guilty of tax evasion or has committed an offence. Many communications are issued for routine processing, verification, corrections or information sharing.
The important thing is to understand the purpose of the notice and respond accurately within the given time.
Final Takeaway
The Income Tax Department issues different types of notices depending on the information available and the action required from the taxpayer. Notices under Sections 142(1), 133(6), 143(1), 143(2), 148, 245, 156 and 139(9) serve different purposes.
Instead of panicking after receiving an income tax notice, taxpayers should verify its authenticity, understand the reason behind it and respond within the prescribed deadline. Timely action and accurate information can help resolve most tax-related issues smoothly.
