What is TAN & How to Apply for TAN in India?

TAN full form is Tax Deduction and Collection Account Number. It is mandated by Section 397 of the Income Tax Act, 2026. This is a 10-digit number that is required for employers deducting TDS on salaries as well as businesses paying contractors. You can apply for a TAN number online through the portal or by using Form 134 or 135. Allotment usually takes 7 to 15 working days. 

Quick Reads

• A valid TAN is legally required for salary tax withholding done by employers and contract payment tax deduction by businesses. 

• You can apply through the Protean portal online or physically with Form 134/135. Processing can take 7 to 15 days digitally.

• Documents such as a PAN card, proof of your identity and address, or a PAO certificate are mandatory. 

• If you fail to obtain or correctly quote a TAN, then you can receive a ₹10,000 penalty. 

• TAN is permanent. It never needs to be renewed after it has been allotted. 

TAN is essentially just an ID number. The Income Tax Department uses it to track every TDS transaction back to the person or business that deducted it. When any tax amount is deducted, that amount gets linked to the TAN number. This link then shows up in the deductee’s Form 26AS. Getting your TAN number itself is a simple and quick process. However, once you have it, you need to ensure that the tax is deducted correctly, the government is paid on time, and that TDS returns are filed on time. 

It is a total of 10 digits and is designated for those who legally need to deduct TDS (tax deducted at source). This is according to Section 397 of the Income Tax Act, 2025. 

The Fixed Structure:

• 4 letters: The first three letters are for the jurisdictional location. The last letter is your name’s initial. 

• 5 digits: These are a unique sequence of numbers designated to everyone. 

• 1 letter: This is a checksum character to ensure accuracy at the end.

For your reference, a sample TAN number looks like: BLRM12345A.

Another important thing to note is that employers need to quote the TAN whenever they deduct TDS from salary, or when a business deducts tax on specific payments. 

A TAN is a must-have when filing TDS returns. The penalty for not having a TAN, or failing to quote it when required, is ₹10,000. 

TAN is required for: 

• Salary payments

• Any rent that exceeds ₹50,000 per month

• Fees paid for professional services that go beyond ₹50,000

• TDS on EPF withdrawals

If you are responsible for deducting or collecting tax, you likely need a TAN, including:

• Employers

• Businesses that make payments to contractors or professionals

• Banks and insurance companies

• Government offices

There is no minimum amount. Even a single transaction that requires TDS needs to have a TAN. 

TAN is also important to ensure tax credits align correctly with the deductor's PAN. This is why employees should verify their Form 16 or TDS certificates.
