Income Tax Notice: How to Check and Authenticate?


Receiving an income tax notice can be an unsettling experience, even if you have filed your returns on time. It is important to understand the different types of notices and how to respond to them appropriately. In this article, we will explore the various notices issued by the income tax department and provide guidance on how to check and authenticate them.

Knowing the Difference Between an Intimation and a Notice

Before diving into the details of income tax notices, it is crucial to Knowing the Difference Between an Intimation and a Notice. An intimation is a message from the income tax division informing you of how your return was processed or the outcome of the assessment. In most cases, you may not be required to take any action upon receiving an intimation. However, there are exceptions where you might need to respond.

On the other hand, a notice requires you to take specific actions. It is important to carefully read the notice to determine the purpose and required response.

Centralized Communication Scheme (CCS)

The Central Board of Direct Taxes (CBDT) has implemented the Centralized Communication Scheme (CCS). Under this scheme, all communications from the income tax department are conducted electronically. Each communication issued by the department after October 1, 2019, bears a unique Document Identification Number (DIN). It is crucial to authenticate any notice or order received from the income tax authority to ensure its genuineness.

Authenticating Notice/Order Issued by ITD

Before responding to any communication from the income tax department, it is advisable to verify its authenticity. On the e-filing portal, you can certified any notices, orders, or letters sent by the income tax authority. Here is a step-by-step guide to authenticate the notice/order:

Step 1: Visit the income tax e-filing portal at and navigate to 'Authenticate Notice/Order Issued by ITD' under 'Quick Links.'

Step 2: You can authenticate using two methods:

  1. For notices/orders/letters issued for AY 2011–12 and subsequent years, the PAN, document type, assessment year, issue date, and mobile number are required.

  2. Document Identification Number (DIN) and mobile number (for all assessment years).

Step 3: Enter the necessary information, such as the PAN, document type, assessment year, issue date, mobile number, and the DIN depending on the method.

Step 4: After entering the details, you will receive an OTP (One-Time Password). Validate the OTP received. Once validated, the DIN of the notice/order issued, along with the date of issue, will be displayed. If the notice/order is not issued by the ITD, a message stating "No record found for the given criteria" will be displayed.

If the notice is not issued by the ITD, if will display a message – No record found for the given criteria.

Step 3(1): An additional option is to authenticate using your mobile number and DIN.

Step 3(2): Continue by entering your mobile number and DIN. An OTP will be sent to you. Use OTP to validate.

A success message similar to the one shown below will be displayed if the notice or order was issued by an income tax authority.

You can make sure the notice or order you received is legitimate and came from the income tax authority by using this authentication process.
