Tax Deduction and Collection Account Number
What does TAN stand for? A banking term, explained.
TAN Full Form in English, letter by letter
TAN is a 10-character alphanumeric number that Indian persons who deduct or collect tax at source must quote on challans, returns and certificates.
TAN Full Form in Indian Languages
Any Indian business that cuts TDS needs a second identifier besides PAN. That is TAN, the Tax Deduction and Collection Account Number, written in six Indian languages below.
What TAN Is For
TAN stands for Tax Deduction and Collection Account Number. It is a ten-character alphanumeric code issued by the Income Tax Department to anyone who must deduct tax at source (TDS) or collect tax at source (TCS).
The logic is simple. When a company pays salary, rent, contractor fees or professional fees above the limits set in the tax law, it must cut tax before paying. That deducted money has to be deposited, reported and certified, and every one of those steps is tagged with the deductor's TAN.
PAN identifies who you are for tax purposes; TAN identifies who you are as a tax deductor. Most companies hold both, and the two numbers are quoted in different places.
Format, Application and Where to Quote It
A TAN has ten characters: four letters, five digits and one letter, for example ABCD12345E. The fourth letter is usually the first letter of the deductor's name. It is applied for in Form 49B, filed online through the authorised agencies NSDL and UTIITSL or on the income tax e-filing portal, with a small processing fee.
Once allotted, TAN must be quoted on every TDS and TCS deposit challan (Form 281), the quarterly TDS returns (forms 24Q, 26Q, 27Q and 27EQ), the TDS certificates issued to deductees (Form 16 and Form 16A), and in correspondence with the department.
Forgetting it is expensive. A return with a wrong or missing TAN can be rejected, and the tax law provides a penalty of ten thousand rupees for failing to apply for or quote the number. Under the old Act this was Section 272BB. The Income-tax Act, 2025 has replaced the 1961 Act from 1 April 2026 and renumbered its sections, so quote the section from the current Act when you write to the department.
Who Does Not Need a TAN
There is one useful exemption. Individuals and Hindu Undivided Families who are not required to get their accounts audited, and who deduct tax only on rent above the monthly limit, on buying immovable property, or on large contract and professional payments (the old sections 194-IB, 194-IA and 194M), can quote their PAN instead of applying for a TAN. A tenant paying a landlord can therefore deduct tax with PAN alone.
Everyone else (companies, firms, LLPs, trusts, societies and businesses that deduct tax under the regular sections) must apply. Deducting tax without a valid TAN is not a defensible position at assessment time, so the number is usually taken care of at incorporation itself.
TDS Thresholds Keep Moving
Recent Changes From the 2025-26 Year
Several TDS thresholds were raised from the 2025-26 financial year. Interest on bank deposits paid to senior citizens now attracts TDS only above one lakh rupees in a year, against fifty thousand earlier, and the limit for other depositors is fifty thousand. The yearly limit for rent was raised to six lakh rupees from a lower monthly-based limit. Fewer small payments attract deduction, so deductors should check the current-year limits before cutting tax.
Finding Your Own or a Deductor's TAN
Your deductor's TAN appears on every TDS certificate you receive (Form 16 from an employer, Form 16A from a bank or tenant). The e-filing portal also has a Know Your TAN search if the certificate is missing, which is handy when a deductor has shut shop.
A Worked Example
A small design studio registered as a private limited company pays a freelance illustrator Rs 80,000 in a year. Because the payment is above the threshold for professional fees, the studio must deduct tax before paying, deposit it with Form 281 quoting the studio's TAN, and file the quarterly return. The illustrator then receives Form 16A, sees the studio's TAN on it, and claims credit for the deducted amount in her own return. If the studio never applied for a TAN, none of that chain works, which is why a new company usually applies for a TAN soon after incorporation.
The Tax Deduction and Collection Account Number is the tag behind every rupee of tax deducted at source in India. Deductors quote it on challans, returns and certificates, and deductees can read their deductor's TAN on Form 16 and Form 16A.
TAN Full Form: Common Questions
What is the full form of TAN?
TAN stands for Tax Deduction and Collection Account Number, a ten-character code issued by the Income Tax Department to persons and entities required to deduct TDS or collect TCS.
Is TAN the same as PAN?
No. PAN identifies a taxpayer, while TAN identifies a tax deductor or collector. Both are ten characters long, but they are allotted separately and quoted in different documents: TAN goes on challans, TDS returns and certificates such as Form 16 and 16A.
Who must apply for a TAN?
Every deductor of TDS or collector of TCS, including companies, firms, LLPs, trusts and businesses that deduct under the regular sections. Individuals and HUFs who deduct only under the special property, rent and large-payment provisions may quote their PAN instead.
How do I apply for TAN and what does it cost?
File an application in Form 49B through NSDL, UTIITSL or the income tax e-filing portal. A small processing fee applies, and the number is usually allotted within days of a complete application.
What happens if I do not quote my TAN?
Returns and challans without the correct TAN can be rejected, which delays credit to deductees. The law also allows a penalty of ten thousand rupees for not applying for or not quoting a TAN.
Is TAN needed to file my own income tax return?
No. A salaried person or ordinary taxpayer files with PAN. TAN matters only if you deduct or collect tax from someone else's payment.
