Understanding Income Tax Notices in India
The Indian income tax department issues notices to taxpayers for various reasons, and being aware of these reasons can help in responding appropriately. Income tax notices are an essential tool the department uses to ensure compliance with tax laws.
Tax administration must be fair, transparent, and reasoned, and not mechanical.
Why Tax Notices Are Issued
Tax notices are issued when there are discrepancies or omissions in taxpayers’ income tax returns. Common reasons include a mismatch in income reporting, non-filing of returns, and other discrepancies. According to a recent report, a significant number of taxpayers receive notices due to incorrect or incomplete information.
How Notices Are Delivered to Taxpayers
Notices are typically delivered electronically to the registered email ID or through the e-filing portal. This digital communication mode ensures that taxpayers receive timely updates and can respond promptly.
“The shift to digital communication has streamlined the process, making it more efficient for both the taxpayer and the income tax department,” said a tax expert.
Why These Notices Matter to Common Taxpayers
Responding to income tax notices is crucial to avoid penalties and fines. Taxpayers must understand the reason for the notice and take appropriate action. Ignoring or delaying a response can lead to further complications.
Types of Income-Tax Notices Explained

ONE-LINE COMPARISON
- 139(9) → “Your return has a defect. Please correct it.”
- 143(1) → “Your return is processed. Here is the adjustment.”
- 148 → “Income may have escaped assessment. Explain why.”
Notice u/s 139(9) – Defective Return
A notice under section 139(9) is issued when there are defects or discrepancies in the income tax return filed by the taxpayer. This could be due to incorrect or missing information.
Common defects
- Mandatory schedules not filled
- Incorrect ITR form
- Audit report not furnished
- Incomplete financial details
Judicial guidance
Courts have held that:
- Minor or technical defects should not invalidate a return without proper opportunity.
- Taxpayers must be given reasonable time to cure defects.
Key judicial principle
A return should not be treated as invalid if the defect is curable and not fundamental.
Practical implication
If the defect is rectified within time, the return remains valid from the original filing date.
Key Features and Time Limits
The taxpayer is given a specific timeframe, usually 15 days, to rectify the defects. Failure to comply may result in the return being treated as invalid.
Example of Section 139(9) – Defective Return
🔹 Situation
Mr. A is a small trader.
He files his income-tax return declaring business income of ₹12 lakh.
However:
- He forgets to upload the tax audit report, OR
- He selects the wrong ITR form, OR
- He leaves mandatory schedules blank
🔹 What Happens
The Income-tax Department issues a notice u/s 139(9) stating that the return filed is defective and asking him to correct the defect within 15 days.
🔹 Correct Action
Mr. A:
- Logs into the income-tax portal
- Uploads the missing audit report / corrects the defect
- Submits the response within time
👉 His return remains valid as if it was correctly filed earlier.
🔹 Wrong Action
If Mr. A ignores the notice:
- His return is treated as invalid
- It is assumed that no return was filed
- He may face late-filing consequences and penalties
🔹 Key Learning
👉 Section 139(9) is a correction opportunity, not a punishment.
Intimation u/s 143(1)
An intimation under section 143(1) is sent when the income tax return is processed, and any adjustments are made. This could involve correcting arithmetical errors or allowing or disallowing deductions.
What adjustments are permitted?
- Arithmetical errors
- Incorrect claims apparent from record
- Mismatch with information available
What is NOT permitted?
Courts have clearly held that:
- Debatable issues cannot be decided under section 143(1)
- No detailed investigation or interpretation is allowed at this stage
🔹 Important judicial principle
If an issue requires explanation, evidence, or interpretation, it cannot be adjusted under section 143(1).
Practical implication
If a taxpayer disagrees with an adjustment, a response must be filed online within the prescribed time.
Processing and Adjustment Mechanism
The processing involves verifying the return for any discrepancies and making necessary adjustments. The taxpayer is then informed of any changes made to their tax liability.
Example of Section 143(1) – Intimation After Processing
🔹 Situation
Mrs. B is a salaried employee.
She files her return claiming:
- Salary income as per Form 16
- Deduction under Section 80C of ₹1.5 lakh
However:
- One deduction claimed by her does not match Form 26AS / AIS
🔹 What Happens
The return is processed by the system and an intimation u/s 143(1) is issued:
- An additional tax demand of ₹8,000 is raised due to mismatch
🔹 Options Before Mrs. B
1️⃣ If she agrees → Pay the demand
2️⃣ If she disagrees → File a response online with explanation
🔹 Important Point
This is not scrutiny.
It is only a computer-based adjustment.
Ignoring the intimation may lead to recovery proceedings.
🔹 Key Learning
👉 Section 143(1) is about arithmetical and data matching errors, not investigation.
Notice u/s 148 (Reassessment)
A notice under section 148 is issued when the income tax department decides to reassess a taxpayer’s income for a previous assessment year. This is typically done when there is reason to believe that income has escaped assessment.
Reassessment proceedings have undergone significant judicial scrutiny, especially after amendments introducing section 148A.
Legal safeguards recognised by courts
Courts have emphasised that:
- Reassessment cannot be initiated mechanically
- Taxpayers must be given a prior opportunity of being heard
- Reasons for reopening must be based on tangible material
🔹 Key judicial principle
Reassessment is a serious matter and must strictly follow statutory procedure and principles of natural justice.
Common grounds for reassessment
- Income reflected in AIS but not disclosed
- High-value transactions
- Information from other agencies
- Foreign income or asset mismatch
Practical caution
Reassessment notices should be handled carefully, as incorrect responses may result in additional amounts, interest, and penalties.
Grounds for Reopening Past Assessments
The grounds for reassessment include having information that suggests income has escaped assessment or detecting errors in the original assessment.
| Notice Type | Purpose | Time Limit for Response |
|---|---|---|
| Notice u/s 139(9) | To rectify defects in the income tax return | 15 days |
| Intimation u/s 143(1) | To inform of adjustments made to the income tax return | 7days to 30 days |
| Notice u/s 148 | To reassess income for a previous assessment year | Specified in the notice, typically 30 days |
Example of Section 148 – Reassessment Notice
🔹 Situation
Mr. C is a professional consultant.
He files his return declaring income of ₹15 lakh.
Later:
- The department receives information through AIS that he received ₹40 lakh as professional receipts from a client
- This income was not disclosed in the return
🔹 What Happens
1️⃣ Mr. C first receives a show-cause notice u/s 148A(b) asking why reassessment should not be initiated
2️⃣ He is given 7–30 days to explain
After considering his reply:
3️⃣ The department passes an order u/s 148A(d)
4️⃣ A formal notice u/s 148 is issued
🔹 What Mr. C Must Do
- File return again in response to notice u/s 148
- Provide explanation and documents
This can result in:
- Additional tax
- Interest
- Penalty (depending on facts)
🔹 Key Learning
👉 Section 148 deals with escaped income and is a serious proceeding requiring careful handling.
