When you start a business and plan to recruit someone as an employee, you must obtain a TAN number. It all started with the CBDT’s (Central Board for Direct Taxes) pay-as-you-earn system, which was designed to provide the government with a consistent source of revenue. When an individual receives money, he is required to pay income tax to the government, and the only way to track this is to deduct tax at the source, which is why it is important for you (or everyone else) to have a TAN.


The Tax Deduction Account Number is abbreviated as TAN. The number must be used if a person wishes to deduct in any TDS correspondence (Tax Deducted at Source). Individuals who are required to deduct tax on payments made by them under the Indian Income Tax Act, 1961 are given a TAN amount.

It is mandatory to quote the Tax Deduction Account Number (TAN) allotted by the Income Tax Department (ITD) in all TDS returns and Challans when depositing the tax in a specified bank under Section 203A of the Income Tax Act, 1961.

Another explanation is that if the TAN is not quoted, TDS returns from individuals will not be issued, and challans for TDS payments will not be approved by banks. If you do not apply for a TAN or do not use it in the necessary paperwork, you will be fined Rs.10, 000.
