Notices may be delivered to any taxpayer who filed suspicious income tax returns under Section 133(6) of the Income Tax Act. This comprehensive guide covers the essentials of Section 133 (6), with its provisions, deadline, case law, and notices, as well as how to submit an appropriate response.

Section 133(6) of the Income Tax Act: An Overview

Certain employees of the income tax department may be required by Section 133(6) to provide information and proof to any taxpayer in connection with tax-related inquiries and actions. The statute gives assessment officers and other department officials the ability to conduct investigations and issue notices requesting information. Taxpayers who declare lower income or withhold income sources may receive such letters. They may also be given for incorrectly claiming exemptions and deductions from income taxes. Notices under this section may also be sent for reasons such as inaccurate or incomplete tax returns, ongoing income tax department investigations, or refusals to file ITRs

Section 133(6) provisions are listed as follows: 

  • Any person, including the assessee, may give notice according to Section 133(6). 

  • As per the guidelines in this section, any information on any subject or account that the designated authorities believe will be pertinent or helpful to any investigation or legal action under the Income Tax Act may be requested. 

  • The information can be requested whether or not there are ongoing legal processes; it is not necessary for there to always be current legal proceedings. 

  • Both the pending proceedings and the status of the proceedings can be determined by calling the information. 

  • The request for information has no time limit.

Not only can the department notify a taxpayer under Section 133(6) of the Income Tax Act, but it can also notify anyone who has information about the transactions of the individual in question. Upon receiving such notices, the recipient is expected to reply with the necessary data. Regarding these inquiries, people are expected to assist the income tax authorities. 

Illustration 1: X paid Y Rs. 20 lakh for items, but when X filed his taxes, he withheld certain information about the transaction. The income tax department may send a notice under section 133 (6) to gather information regarding this transaction if it decides to investigate X further. Now that the transaction's invoice details have been provided, X must file revised returns and make any necessary adjustments.

Illustration 2: Before moving to the USA in FY2020 for work, Z was an Indian citizen. He still receives money from India through several investments, but he hasn't submitted an ITR for them. The income tax authorities in this case issue a notice under section 133(6) requesting that all bank and demat statements demonstrating his income from both India and the foreign nation be submitted. Z faces sanctions from the AO if he does not produce these documents within 20 days.

Who can File a Notice under Section 133(6)

The following individuals may submit notices for information about tax inquiries and proceedings in accordance with Section 133(6): 

  • Officer of Assessment (AO) 

  • Deputy Commissioner (Appeals) 

  • Co-Commissioner 

  • Commissioner in Common (Appeals) 

  • Chief Commissioner or Director General 

The aforementioned authorities are granted to individuals holding a position higher than assistant director or assistant commissioner in cases of taxpayer noncompliance in nations where the Double Taxation Avoidance Agreement (DTAA) is in effect.

Penalty for Failing to Respond to a Notice under Section 133(6)

The following may happen if you don't respond to a notice from the income tax department or if they don't think your response is good enough: 

  • According to Section 148 of the Income Tax, the Assessing Officer sends you a second notice after finding your tax returns to be invalid. This notice mandates that the person file amended income tax returns and, within the allotted period, explain any arrears. 

  • In addition to declaring extra income or withdrawing claims for exemptions and deductions for which there is insufficient evidence, the department may request that the taxpayer file amended tax returns. 

  • Section 272A (2) of the Income Tax Act imposes penalties for noncompliance with the AO's instructions. The penalty can be as little as Rs. 100 each day up until the filing of amended returns, or it can be more severe. 

  • If the inquiry reveals false income claims or deductions, the taxpayer will be required to pay 200% in penalties for evading taxes, together with penal interest at the rate of 12% per year. In addition to fines, incarceration might come from prosecution. 


Finally, make sure to reply right away if you receive a notice under Section 133(6) of the Income Tax. Respond with the necessary details, and if necessary, enlist the assistance of a specialist such as a chartered accountant. To address any problems, it is important to keep records about tax filing for a minimum of ten years.
