Notice From Income Tax Department? Here’s What to Do – Complete Step-by-Step Guide (India)

Receiving a notice from Income Tax Department can instantly create stress. Many taxpayers panic the moment they see an official email or letter mentioning sections like 143(1), 139(9), or 148. But here’s the truth — most income tax notices are routine and manageable if handled properly and on time.

If you’ve received a notice, don’t ignore it and don’t panic. In this detailed guide, we’ll explain why you may have received it, what different notices mean, and exactly what steps you should take next.


📩 Why Do You Receive an Income Tax Notice?

The Income Tax Department issues notices for several reasons. Some are simple clarifications, while others require correction or additional documentation.

Common reasons include:

  • Mismatch between ITR and Form 26AS/AIS

  • High-value transactions reported by banks

  • Incorrect income details

  • Failure to file return

  • Claiming excessive deductions

  • TDS mismatch

  • Scrutiny assessment selection

Most notices are system-generated due to data mismatches.


📄 Types of Common Income Tax Notices in India

Understanding the section mentioned in the notice is very important.

1️⃣ Section 143(1) – Intimation Notice

This is the most common notice. It is simply a comparison between your filed return and department records. It may show:

  • No demand, no refund

  • Refund issued

  • Tax demand raised

👉 This is not a penalty notice. It’s just an intimation.


2️⃣ Section 139(9) – Defective Return Notice

This notice means your return was filed incorrectly or missing information.
You usually get 15 days to correct it.

Common reasons:

  • Missing income details

  • Incorrect tax calculation

  • Missing audit report


3️⃣ Section 143(2) – Scrutiny Notice

This is more serious. Your return has been selected for detailed examination. You may need to submit:

  • Bank statements

  • Investment proofs

  • Salary slips

  • Business records

Professional help is strongly advised in such cases.


4️⃣ Section 148 – Income Escaped Assessment

This notice is issued if the department believes you did not report certain income. It may relate to previous assessment years.

Immediate action and CA consultation is recommended.


5️⃣ Section 245 – Adjustment Notice

This means your refund is being adjusted against past tax demand.
