Section 147A
Section 147 of the Income Tax Act, 1961 provides for the reopening of assessment proceedings. This section gives discretion to the Assessing Officer (AO) to reopen the assessment proceedings when he/she has reason to believe that some of the income has escaped assessment.
Every earning individual is required to file the return to the income tax department if the earning is chargeable to tax. The tax authorities examine your income tax return (ITR) and if necessary, they can seek additional clarifications. This process of examining the return of income is referred to as assessment.

under Section 147 of the ITA
For instance, anything you earned in the financial year (FY) 2023-24 is assessed in the assessment year (AY) 2024-25. After self-assessment, the taxpayer will compute the tax liability and will have to pay that amount and file ITR. Thereafter, the income tax department (ITD) conducts preliminary checking of returns for any arithmetical errors, incorrect claims, etc., which is a fully computerised process. At this stage, there is no detailed scrutiny of ITR filed.

Overview
Section 147 of the Income Tax Act, 1961, deals with the reassessment of income by the Income Tax Department. It empowers tax authorities to reopen completed assessments if they have reason to believe that income has escaped assessment. With several amendments in recent years, especially through the Finance Acts of 2021 and 2022, this section has gained significant importance in tax administration and compliance. This blog will help you understand Section 147 in simple language, including the procedure, key terms, and taxpayer rights.
What is Section 147 of the Income Tax Act?
Section 147 grants the Assessing Officer (AO) the authority to assess or reassess income if it is believed that any income chargeable to tax has escaped assessment. This may include cases where no return was filed or where income was under-reported in a previously filed return.
Key Point: This section plays a crucial role in ensuring that all taxable income is brought under the tax net, even after an assessment has been completed.
What is Section 147 of the Income Tax Act?
- Assessment: The original evaluation of a taxpayer’s income and tax liability.
- Reassessment: A fresh assessment done by the AO if they find that income was missed during the original assessment.
- Income Escaping Assessment:Any part of income that was not taxed earlier due to oversight, misreporting, or new evidence.
- Reason to Believe: A key phrase indicating that the AO must have a justified basis to reopen a case.
Key Terms in Section 147: Assessment and Reassessment
There are several types of assessments conducted by the Income Tax Department:
- Self-Assessment (Section 140A) – Done by the taxpayer.
- Summary Assessment (Section 143(1)) – Done automatically based on return filed.

The Finance Act, 2021 introduced major changes to Section 147:

Mini Case Study: How Section 147 is Applied
Example: Mr. A files his ITR showing ₹8 lakh income. Later, a large deposit of ₹25 lakh in his bank account is flagged via AIS. The AO initiates inquiry under Section 148A and finds that the source of funds was not explained. AO issues notice under Section 148, and reassessment under Section 147 leads to additional tax demand.

Right to be Heard: Taxpayers must be given a chance to explain before reassessment.

Conclusion
Section 147 of the Income Tax Act is a powerful tool for the Income Tax Department to address tax evasion and bring unreported income under the tax net. However, with recent amendments, the reassessment process has become more transparent and taxpayer-friendly. Understanding this section helps both individuals and businesses stay compliant and protect their rights.
If you're unsure about how Section 147 applies to your case or have received a notice, it’s best to consult a qualified tax professional or CA.
Frequently Asked Questions
If you receive a notice under Section 147 (or Section 148), follow these steps to respond:
- Read the notice carefully to understand the reason for reassessment.
- Login to the Income Tax Portal (https://www.incometax.gov.in/) and navigate to the ‘e-Proceedings’ section.
- Submit your response along with relevant documents or explanations supporting your original return.
- If the notice asks for a fresh return (under Section 148), file it within the time limit specified (usually 30 days).
- Consult a tax professional or CA to draft a strong and accurate reply.
Pro Tip: Always respond within the deadline and maintain polite, factual communication. Ignoring the notice can lead to penalties or even prosecution.
As per the Finance Act, 2021, the time limits for reopening assessments under Section 147 are:
- Normal cases (income escaping < ₹50 lakh): Reassessment can be initiated within 3 years from the end of the relevant Assessment Year.
- Serious cases (income escaping ≥ ₹50 lakh and involves assets, expenditure, or entry): AO can reopen up to 10 years from the end of the relevant Assessment Year.
Also, no reassessment can be done after 3 years unless the AO has "evidence-based information" of significant income escaping assessment.
Note: The timelines are strictly enforced to ensure fairness and to protect taxpayer rights.
While Section 147 itself does not impose penalties, reassessment may lead to additional tax, interest, and penalties under related sections if the AO finds unreported income.
Here’s what you could face:
- Interest under Section 234A/B/C for delay in tax payment or filing.
- Penalty under Section 270A for underreporting (50% of tax shortfall) or misreporting of income (200% of tax shortfall).
- Prosecution under Section 276CC in cases of willful evasion (rare but applicable in extreme cases).
Best Practice: Always declare all income truthfully and keep transaction records to avoid penalties.
Here are the most common triggers that lead to reassessment notices:
- High-value cash or property transactions not declared.
- Mismatch between AIS/TIS and ITR.
- Incorrect claims of deductions or exemptions.
- Non-filing of ITR despite TDS being deducted.
- Undisclosed foreign assets or investments.
The tax department uses AI-powered systems to detect such mismatches and anomalies.
Yes. If you receive a notice under Section 148 (related to Section 147), you must file a fresh income tax return within the time mentioned in the notice. Not responding may lead to best judgment assessment under Section 144 and attract penalties.
Ignoring the notice is never a good idea. Even if you believe your original ITR was correct, you must comply and explain your case properly.
Section 147 of the Income Tax Act itself is not a criminal section — it deals with the reassessment of escaped income. Receiving a notice under Section 147 is not an offense; it’s a compliance opportunity.
However, if during reassessment, it's found that you deliberately evaded taxes, you may face prosecution under Section 276CC or Section 277. In that case:
- Yes, the offenses under Section 276CC (non-filing) are bailable but serious misreporting can escalate it to non-bailable depending on intent and amount.
Key takeaway: Section 147 itself is civil in nature. It becomes criminal only if tax evasion is proved with intent.
