01What is TAN and who needs to obtain it?
TAN (Tax Deduction and Collection Account Number) is a 10-digit alphanumeric number required by any person or entity responsible for deducting or collecting tax at source. It is mandatory for employers deducting TDS on salary, businesses deducting TDS on payments, and government offices. Individuals are generally not required to obtain TAN.
02How do I apply for a TAN?
TAN can be applied for online through the NSDL TIN portal (tin.tin.nsdl.com) using Form 49B. The fee is Rs 65 plus GST. Application can also be made offline through TIN Facilitation Centres. The TAN is typically issued within 7-10 working days after application.
03Can I look up a TAN for a deductor?
Yes. TAN can be verified on the income tax portal (incometax.gov.in) under "Know Your TAN." Enter the deductor's category, state, and name or TAN number. The result shows the TAN and deductor details. This is useful to verify TAN mentioned on TDS certificates.
04What is the penalty for not quoting TAN in TDS documents?
Not quoting TAN or quoting an incorrect TAN in TDS challans, TDS returns, or TDS certificates attracts a penalty of Rs 10,000 under Section 272BB of the Income Tax Act. All TDS-related documents must carry the correct TAN of the deductor.
05Can a company have multiple TANs?
A company can have multiple TANs for different branches or offices if each branch independently handles TDS deduction. However, the tax department discourages multiple TANs and encourages consolidation. If duplicate TANs exist, they should be surrendered to the assessing officer.
