What is TAN? and Why is TAN Necessary?

TAN stands for Tax Deduction and Collection Account Number. The Income Tax Department issues TAN to taxpayers. Moreover, individuals and businesses who are obligated by the Income Tax Act of 1961 to deduct or pay tax on payments, are required to receive TAN. 

A TAN is essential for everyone who must deduct tax at source (TDS) or collect TCS. A tax deductor as well as a collector receives a 10-digit alphanumeric number which is similar to PAN. The person who submits an application for this number will receive it from the IRS. The taxpayer must use the TAN for all TDS or TCS payments and mention it on every TDS return and Form 16. If a person deducting tax at source does not have a TAN, they may face a penalty of up to Rs. 10,000. Failure to quote TAN in TDS challans and TDS certificates is also subject to a penalty of Rs.10,000.

Who Should Apply For TAN?

All taxpayers who are responsible for deducting tax at source (TDS) or collecting tax at source (TCS) must get a TAN. The first four digits of TAN are alphabets, the next five are numeric, and the final one is an alphabet.
