Understanding Income Tax Reassessment in India
In India, the Income Tax Department is empowered to reopen a previously assessed or processed return if it believes that some income has escaped assessment. This process is called Income Tax Reassessment and is governed by Section 147 to Section 151 of the Income Tax Act, 1961.
Reassessment is a serious legal action that can have significant tax implications. Whether you are an individual taxpayer, a business owner, or a tax consultant, understanding the reassessment provisions can help you respond properly and protect your interests.
What is Income Tax Reassessment?
Reassessment refers to the reopening of a completed income tax assessment by the Assessing Officer (AO) when they have reason to believe that taxable income has been underreported, omitted, or not assessed at all in a particular financial year.
It is different from a rectification (under Section 154), which deals with clerical or calculation errors. Reassessment involves a fresh scrutiny of income due to new or previously overlooked information.
Legal Framework: Key Sections Governing Reassessment
Section 147 – Income Escaping Assessment
This is the core section that allows the Assessing Officer to assess or reassess income if they have reason to believe that any income chargeable to tax has escaped assessment.
The term “escaped assessment” includes:
- Omitted income due to failure to file a return
- Incorrect claims or deductions
- Income assessed at a lower rate
- New evidence of undisclosed income
Section 148 – Issue of Notice
Before reassessing, the AO must serve a notice under Section 148, asking the assessee to furnish a return for the relevant assessment year.
From 1 April 2021, the Finance Act 2021 introduced a new procedure where the AO must first conduct an inquiry under Section 148A and provide the assessee an opportunity to respond.
Section 148A – Preliminary Inquiry Before Issuing Notice
This section mandates:
- AO to conduct an enquiry with prior approval
- Opportunity to be given to the assessee to explain why reassessment is not warranted
- Decision to issue notice only after considering the assessee’s reply
Section 149 – Time Limits for Issuing Notice
The reassessment notice can be issued:
- Within 3 years from the end of the relevant assessment year, if the escaped income is below ₹50 lakh
- Up to 10 years if the escaped income is ₹50 lakh or more and represented in the form of an asset, expenditure, or entry
Section 151 – Sanction for Issue of Notice
This section outlines the approval required before initiating reassessment. For example, if more than three years have passed, approval from a senior officer (Principal Chief Commissioner or Principal Director General) is mandatory.
Common Grounds for Reassessment
Some frequent triggers for income tax reassessment in India include:
- Information from search, survey, or investigation
- Large cash deposits or high-value transactions not disclosed in returns
- Information shared by other government departments or foreign jurisdictions
- Misreporting of capital gains, especially on property or shares
- Non-disclosure of foreign income or assets
