What is a TAN application?

A 10-digit alphanumeric number called the TAN, or Tax Deduction and Collection Account Number, is necessary to withhold and deposit tax at the source. It is a special identifying number given to people, organizations, and businesses by the Income Tax Department of India if they must withhold or collect tax at the source.

To apply for a TAN Number, you must submit Form 49B, which is correctly filled out and signed, as well as the required paperwork and the application fee. Through the NSDL or UTIITSL portals, TAN applications can be submitted online. The Income Tax Department issues the TAN to the applicant after processing and verifying the application. To comply with Indian income tax laws, all entities—including people, partnerships, businesses, and trusts—must obtain TANs.

What is the Structure of the TAN Number?

The correct structure of a TAN is as follows: ABBBB89899C

  1. City or State Code: The first three characters in the TAN represent the city or state where the TAN was issued. These characters help identify the location of the TAN holder.
  2. Initial Letter: The fourth character in the TAN corresponds to the tax deductor’s initial letter. It signifies that the name of the Tax Deductor begins with this particular letter.
  3. Numeric Numbers: The next five characters in the TAN are system-generated numeric numbers. These numbers are assigned by the system and do not hold any specific significance or meaning.
  4. Check Digit: The last character in the TAN is an alphabetic number, known as the check digit. It is generated by the system and serves as a verification digit to ensure the accuracy and integrity of the TAN.
