TAN registration refers to the process of obtaining a 10-digit alphanumeric code by every entity deducting or collecting tax at source under section 203A of the Income Tax Act, 1961. Registration of a TAN number can be done either offline or online through the Tax Information Network portal (formerly NSDL), making it accessible to all types of taxpayers.
In India, most entrepreneurs and SMEs who obtain TAN without registration enjoy quoting TDS/TCS returns, challans, and certificates to the Income Tax Department. In simple terms, without TAN, your TDS returns are effectively rejected. Get connected if you do not hold a TAN number and are looking to file the TDS/TCS return in India.

The benefits of obtaining TAN registration approval are as discussed below:

Obtaining TAN registration approval helps verify, report, and avoid errors in TDS returns and when issuing TDS certificates.
Obtaining TAN registration approval ensures compliance with section 203A to avoid legal hefty penalties under section 272BB.
Obtaining TAN registration approval simplifies payroll and accounting for Forms 16 and 16A, as well as salary TDS deductions.
Obtaining a TAN registration number ensures proper compliance during audits and the processing of income tax refunds.
Obtaining a TAN registration facilitates the legal deposit of TDS with the central government, thereby enhancing the business's credibility with financial institutions and partners.
TAN registration provides TAN holders with an authenticated login area on the TRACES portal, allowing them to download a justification report and check the challan status online.
