TAN: The Deductor’s Identity Number

PAN identifies a taxpayer. TAN identifies whoever is taking tax out of a payment before it reaches them. A business or individual with TDS or TCS obligations needs both, not one instead of the other.

Income Tax Basics

Allowances and Perquisites

Section numbers here are from the Income tax Act, 1961, the operative law for the current filing cycle; new Section 397 corresponds to old Section 203A. Application forms and procedures can change. This article is for general information and does not constitute tax advice.

What It Is, and Who Needs One

TAN, Tax Deduction and Collection Account Number, is a 10-character alphanumeric identifier issued to every person responsible for deducting TDS or collecting TCS, required under new Section 397 (old Section 203A) before the first such deduction is made. Employers deducting on salaries, businesses deducting on rent, professional fees, or contractor payments above the relevant thresholds, and anyone else required to deduct or collect tax, all need one. A salaried individual with no deduction obligation of their own generally doesn’t. The format: first three characters a jurisdiction code, the fourth the initial of the deductor’s name, five digits, a final check letter — e.g. BLRM12345A.

How to Apply, and Where It’s Quoted

From 1 April 2026, applications use new forms replacing Form 49B: Form 134 for Government deductors, Form 135 for everyone else in the private sector (individuals, HUFs, companies, LLPs, firms, trusts). Filed online through the Protean TIN website or the income tax e-filing portal, or offline through a TIN Facilitation Centre. TAN must appear on every TDS/TCS return, on payment challans, and on certificates issued to deductees (Form 16, Form 16A, Form 27D).

Penalty, Validity, and Verification

Failing to apply when required, or quoting an incorrect TAN, attracts a ₹10,000 penalty under new Section 468 (old Section 272BB). Once issued, a TAN never expires and needs no renewal, though it can be surrendered if a business closes or stops having any TDS/TCS obligation, via a cancellation request to the jurisdictional assessing officer. The “Know Your TAN” facility on the e-filing portal allows verification by name or number — useful both for a deductor confirming its own details and for a deductee checking a TAN quoted on a certificate.

FAQs: TAN

Can a business use its PAN instead of applying for a TAN?

No. They serve different purposes and can’t substitute for each other. A deductor needs its own PAN as a taxpayer and a separate TAN specifically for TDS/TCS compliance.

Does every business need a TAN, or only larger ones?

It depends on whether a TDS or TCS obligation actually applies, not on business size directly. Once a payment crosses the threshold that triggers deduction, a TAN is needed regardless of how small the business is.

What happens if tax is deducted without a valid TAN?

The deduction itself can happen, but depositing that tax and filing the corresponding TDS return isn’t possible without a valid TAN, and the deductor also becomes liable for the ₹10,000 penalty on top of needing to obtain one to regularise the position.

Does TAN transfer along with a business if it’s sold?

No. It belongs to the deductor entity itself. A new owner with its own TDS or TCS obligations needs to apply for its own TAN rather than inheriting the previous one.

Does an individual buying property from an NRI need a TAN?

Yes, in most such cases. An individual required to deduct TDS on a payment to a non-resident generally needs a TAN for that deduction — a requirement that catches many individual buyers by surprise since it doesn’t otherwise come up in ordinary salaried filings.

If a business already holds a TAN, does it need to reapply because of the new Act?

No. TANs already issued remain fully valid. The new application forms apply only to fresh applications and corrections made from 1 April 2026 onward.
