Understanding Income Tax Notices: Why You May Receive One and How to Respond

Filing an Income Tax Return (ITR) accurately is crucial to avoid potential notices from the Income Tax Department. If any discrepancies or errors are found in a taxpayer's filed ITR, the department may issue a notice seeking clarification or corrective action. Knowing the types of income tax notices and the reasons behind them can help taxpayers respond appropriately and avoid further complications.

While there are multiple types of tax notices, not all of them apply to individuals. Below are some of the most common notices that a salaried individual might receive due to errors in their ITR:

1. Intimation Notice Under Section 143(1)(a)

This notice is sent after the tax department processes an ITR and serves as an official communication regarding discrepancies between the taxpayer’s reported income and the department’s calculations. It informs whether the ITR has been accepted as filed or if there are mismatches that require correction.

Possible Reasons for Receiving This Notice:

• Differences between income reported in the ITR and income calculated by the department under Section 143(1)
• Arithmetical errors in the return
• Incorrect tax deductions or exemptions claimed
• Mismatch between the taxpayer’s ITR and Form 26AS

Response Timeline:

• If the notice indicates a refund or confirms no discrepancies, no response is required.
• If a mismatch is found, taxpayers must respond within 30 days of receiving the notice.

2. Defective Return Notice Under Section 139(9)

A notice under Section 139(9) is issued when the ITR contains incomplete or incorrect information, making it "defective." This means that the return must be corrected and resubmitted.

Common Reasons for Receiving This Notice:

• Filing the ITR using an incorrect form
• Claiming House Rent Allowance (HRA) despite no HRA component in the salary
• Claiming Tax Deducted at Source (TDS) without reporting the corresponding income (e.g., FD interest)

Response Timeline:

• The taxpayer has 15 days from the date of receipt to correct the return.
• An extension can be requested if additional time is needed.

3. Notice Under Section 148 – Inquiry Before Reassessment

This notice is issued when the tax department suspects that a taxpayer has income that was not reported and has therefore "escaped assessment." The taxpayer is required to explain why an ITR was not filed despite evidence of taxable income.

Possible Reasons for Receiving This Notice:

• Failure to file an ITR despite having taxable income
• Significant income discrepancies detected by the tax department

Response Timeline:

• The response must be submitted within 15 days or within the period specified in the notice.

4. Scrutiny Notice Under Section 143(2)

A Section 143(2) notice indicates that the ITR has been selected for scrutiny assessment. This means the department wants to conduct a detailed review to verify the accuracy of the claims made in the return.

Possible Reasons for Scrutiny:

• Large or unusual tax deductions
• Significant variation in income from previous years
• Inconsistencies between declared income and third-party financial records

Response Timeline:

• The taxpayer is usually given 15 days to respond, but the deadline will be mentioned in the notice.

5. Notice Under Section 148 – Reassessment of Escaped Income

A Section 148 notice is issued when the assessing officer (AO) has evidence that a taxpayer's income has escaped taxation. Before reassessing the case, the department issues this notice to seek clarification.

Time Limit for Issuing This Notice:

• If the unassessed income is ₹50 lakh or less, the notice can be issued within 3 years and 3 months from the end of the relevant assessment year.
• If the unassessed income exceeds ₹50 lakh, reassessment can be conducted for up to 5 years and 3 months.

Response Timeline:

• The taxpayer must respond within 30 days of receiving the notice.

6. Notice Under Section 245 – Tax Refund Adjustment Against Outstanding Dues

If a taxpayer has pending tax dues from a previous year, the tax department may adjust the current year’s tax refund against the outstanding dues and issue a Section 245 notice to inform the taxpayer about this adjustment.

Response Timeline:

• If the taxpayer disagrees with the notice or has already paid the due amount, they must respond with proof of tax payment within 30 days.

Other Notices Taxpayers May Receive:

Section 154 – Rectification Notice

If errors are found in an already accepted ITR, the tax department may issue a Section 154 notice to correct the mistakes.

Section 263 – Revision of Erroneous Order

If the Commissioner of Income Tax (CIT) finds an assessment order incorrect and detrimental to government revenue, they may issue a notice under Section 263 within 12 months to modify the order.

Section 131(1A) – Investigation for Concealed Income

If senior tax officials suspect that a taxpayer is hiding income, a Section 131(1A) notice may be issued. The taxpayer must provide a response and supporting documents within 30 days.
