Tax Deduction and Collection Account Number (TAN)
Tax Deduction and Collection Account Number (TAN) is a 10-digit alphanumeric identifier issued under Section 203A of the Income Tax Act, 1961 to every person required to deduct or collect tax at source, and is mandatory on all TDS/TCS returns, challans, and certificates.
TAN is the foundational identification number for entities that deduct or collect tax at source under the Indian income tax framework. Just as PAN identifies the taxpayer, TAN identifies the deductor or collector for the purposes of withholding tax compliance. Section 203A makes it an obligation for any person required to deduct tax under Chapter XVII-B or collect tax under Chapter XVII-BB to apply for and quote TAN in all TDS/TCS-related documentation.
The structure of TAN is a 10-character alphanumeric code formatted as four alphabets followed by five digits followed by one alphabet. The first three letters represent the city or state where the TAN was issued, the fourth letter represents the initial of the deductor's name, and the remaining six characters are system-generated. For example, a Mumbai-based entity with surname beginning with M may receive a TAN like MUMM12345A.
TAN is applied for through Form 49B, which can be submitted offline at TIN Facilitation Centres or online through the NSDL (now Protean eGov Technologies) portal. The processing fee is nominal. Once issued, TAN is permanent and does not change unless there is a change in the structure of the entity. Corporate mergers, demergers, or reconstruction may necessitate fresh TAN applications for the resultant entities.
Quoting TAN is mandatory on quarterly TDS/TCS returns (Forms 24Q, 26Q, 27Q, 27EQ), TDS/TCS payment challans (ITNS 281), TDS certificates issued to deductees (Form 16, 16A), and all correspondence with the Income Tax Department relating to withholding tax. Failure to apply for TAN, failure to quote TAN, or quoting of incorrect TAN attracts a penalty of Rs. 10,000 under Section 272BB.
Large organisations often hold multiple TANs for different divisions, branches, or payroll entities. Rationalising TAN usage, ensuring timely deposit of TDS into the correct TAN, and filing quarterly returns accurately under the right TAN are critical compliance activities. Errors in TAN attribution can result in mismatches in the deductee's Form 26AS, causing refund complications for the deductee and notice exposure for the deductor.
