How to Respond to an Income Tax Notice — Complete Guide

What is an Income Tax Notice?

An income tax notice is an official communication from the Income Tax Department regarding your tax filing, assessment, or compliance. Receiving a notice doesn't always mean something is wrong — many notices are routine and require simple responses.

Common reasons for receiving notices include:

• Discrepancies between your ITR and Form 26AS/AIS
• Non-filing of income tax return
• Defective return with errors or missing information
• Scrutiny assessment for detailed verification
• Demand notice for outstanding tax dues
• Refund adjustment against pending demands

All income tax notices are now delivered electronically to your registered email and the Income Tax e-filing portal.

Types of Income Tax Notices

Section 143(1) — Intimation Notice

The most common notice. It's an auto-generated intimation after your ITR is processed, showing:

• Tax as computed by the department
• Any mismatch with your declared income or TDS
• Refund due or additional tax payable

Action needed: If the computation matches, no action required. If there's a mismatch, file a rectification under Section 154.

Section 139(9) — Defective Return Notice

Issued when your ITR has errors or missing information, such as:

• Incorrect ITR form used
• Missing schedules or disclosures
• Mismatch between income and deductions

Action needed: Correct the defect and file a revised return within 15 days (extendable on request).

Section 142(1) — Inquiry Notice

Sent when the department needs more information before completing your assessment:

• Request for additional documents
• Specific queries about income or deductions
• Books of accounts

Action needed: Submit the requested information within the specified timeline.

Section 143(2) — Scrutiny Notice

A serious notice indicating your return has been selected for detailed scrutiny. This means an assessing officer will examine your return closely.

Action needed: Prepare all supporting documents. You may want to engage a Chartered Accountant. Respond within the given timeline — usually 3-6 months.

Section 148 — Reassessment Notice

Issued when the department believes income has escaped assessment. Can be issued within specific time limits:

• 3 years from end of assessment year for regular cases
• 10 years for cases involving income escaping assessment above ₹50 lakh

Action needed: File a return in response to the notice. Seek professional help as this is serious.

Section 245 — Refund Adjustment Notice

Sent when the department wants to adjust your pending refund against outstanding tax demands from previous years.

Action needed: If you agree, no action needed. If you disagree, respond with reasons within 30 days.

Section 156 — Demand Notice

Issued when tax, interest, or penalty is payable after assessment.

Action needed: Pay the demand or file an appeal if you disagree.

Section 131(1A) — Search/Seizure

Issued in cases of suspected tax evasion for search and seizure operations.
