Quick Answer

A TAN (Tax Deduction and Collection Account Number) is a 10-character alphanumeric ID that every person who deducts TDS or collects TCS must obtain under Section 203A. Apply online through Form 49B on the Protean (formerly NSDL) TIN portal or the income-tax portal; the government fee is about Rs 65 + GST (~Rs 77) and the TAN is usually allotted in 7–10 working days. Without a valid TAN you cannot file TDS returns and face a Rs 10,000 penalty under Section 272BB.

PAN is not a substitute for TAN

A PAN identifies a taxpayer; a TAN identifies a deductor. TDS returns (24Q/26Q/27EQ) and TDS challans (Challan 281) require a TAN, not a PAN. The only exceptions where PAN is used instead of TAN are the one-off deductions under Sections 194-IA (property purchase, Form 26QB), 194-IB (rent by individuals/HUF) and 194M (contract/professional payments by individuals/HUF) — none of which need a TAN.

Who is covered

Who Needs a TAN?

Anyone responsible for deducting TDS or collecting TCS must hold a TAN. The table maps the common situations, including where TDS can be paid on PAN alone.

Deductor / situationTAN?Basis
Company paying salary, rent or professional feesYesTDS u/s 192, 194-I, 194J
Firm / LLP with TDS obligationsYesTDS on contractor / professional / salary payments
Individual/business under tax audit deducting TDSYesAudit case → regular TDS deductor
Individual buying property over Rs 50 lakhNoSec 194-IA — PAN & Form 26QB (1%)
Individual/HUF (no audit) paying rent over Rs 50,000/moNoSec 194-IB — PAN, 2% once a year
Government deductor (ministry / PSU)YesFiles 24G; BIN for book-entry TDS

Sec 194-IB rate was cut from 5% to 2% and the Sec 194-I annual rent threshold raised to Rs 6 lakh (Rs 50,000/month) — both from 1 April 2025 (Budget 2025).

Step by step

How to Apply for TAN Online (Form 49B)

TAN Structure — How to Read a TAN

A TAN looks like MUMB12345C — four letters, five digits and a check letter. Each part is meaningful:

PositionCharactersMeaning
1–3Letters (MUM)City / jurisdiction code of the TDS office
4Letter (B)First letter of the deductor's name
5–9Digits (12345)System-generated sequential number
10Letter (C)Alphabetic check digit

Once allotted, quote the TAN on every TDS challan (Challan 281), every TDS return and every TDS certificate such as Form 16 / 16A. You can verify a TAN under "Know Your TAN" on the income-tax portal.

✓You must get a TAN if

  • You are a company, firm or LLP deducting any TDS
  • You run a business under tax audit and deduct TDS
  • You collect TCS on sale of goods, scrap, etc. u/s 206C

!You can skip TAN (use PAN) if

  • You are an individual buying property (194-IA, Form 26QB)
  • You are a non-audit individual/HUF paying rent (194-IB)
  • You make one-off contract/professional payments (194M)
The cost of skipping

Penalty for Not Obtaining a TAN

Failing to apply for a TAN, or quoting a wrong TAN on returns and challans, attracts a flat penalty under Section 272BB. The knock-on TDS consequences are usually costlier than the penalty itself.

  • Rs 10,000 penalty under Section 272BB for not obtaining a TAN or quoting an incorrect one
  • TDS returns (24Q, 26Q, 27EQ) cannot be filed without a valid TAN
  • Deductees do not get their TDS credit in Form 26AS / AIS, because credit is matched on the deductor's TAN
  • Being treated as an assessee-in-default u/s 201, with 1%/1.5% per month interest on the TDS involved
One TAN per deductor, quoted everywhere

A deductor generally needs only one TAN, used across all TDS sections and returns. Multiple TANs for the same entity should be surrendered to avoid mismatch. Quote the same TAN on Challan 281, GSTR-independent TDS returns and every TDS certificate to keep Form 26AS credits flowing to your deductees.

TAN Registration — Frequently Asked Questions

Short, direct answers to the 15 questions readers ask most on this topic.

TAN stands for Tax Deduction and Collection Account Number — a 10-character alphanumeric identifier required under Section 203A for every person who deducts TDS or collects TCS. It is allotted by the Income Tax Department, with applications processed through Protean (formerly NSDL e-Gov) or the income-tax portal. The TAN must be quoted on all TDS/TCS challans, returns and certificates.

PAN (Permanent Account Number) identifies a taxpayer and is used for filing income-tax returns and general tax compliance by everyone. TAN (Tax Deduction and Collection Account Number) identifies a deductor and is used only for TDS/TCS — on TDS returns (24Q, 26Q, 27EQ) and TDS challans (Challan 281). A PAN cannot replace a TAN for regular TDS, except in the specific PAN-based deductions under Sections 194-IA, 194-IB and 194M.

A TAN such as MUMB12345C has four letters, five digits and a check letter. The first three letters are the jurisdiction/city code of the TDS office, the fourth letter is the first letter of the deductor's name, the next five are a system-generated sequential number, and the last character is an alphabetic check digit.

Every business that deducts TDS or collects TCS needs a TAN. Companies, LLPs and firms almost always do, because they pay salaries, rent, contractor and professional fees on which TDS applies. A small individual or proprietor not under tax audit and with no TDS obligation may not need one — but the moment a TDS-triggering payment is made, a TAN becomes mandatory.

Usually not. Most individuals have no TDS obligation. An individual needs a TAN only if they carry on a business or profession under tax audit and deduct TDS. Even large one-off payments are handled on PAN: property purchase over Rs 50 lakh (Section 194-IA, Form 26QB), rent over Rs 50,000 a month by a non-audit individual/HUF (Section 194-IB), and contract/professional payments (Section 194M) all use PAN, not a TAN.

No. Under Section 194-IA, the buyer of an immovable property where consideration is Rs 50 lakh or more deducts 1% TDS using their own PAN and deposits it through Form 26QB — no TAN is required. The buyer then issues Form 16B to the seller. A TAN is needed only for regular property-related TDS such as rent under Section 194-I by a company.

If you are an individual or HUF not subject to tax audit, no. Section 194-IB lets you deduct TDS on your PAN once a year, and from 1 April 2025 the rate was reduced from 5% to 2%. A TAN is required only if you are a business/company deducting rent TDS under Section 194-I, whose annual threshold was raised to Rs 6 lakh (Rs 50,000/month) in Budget 2025.

Apply in Form 49B on the Protean (NSDL) TIN portal or through the income-tax portal. Select your deductor category, fill in name, address, PAN and the responsible person's details, pay the fee online, and note the 14-digit acknowledgement number to track the request. The TAN is emailed and posted to the registered address, usually within 7-10 working days.

The government processing fee is about Rs 65 plus GST, which works out to roughly Rs 77 in total for an online application. The fee is non-refundable even if the application is rejected. TaxClue can file Form 49B and set up your TDS returns for a professional fee on top of the government charge.

Typically 7 to 10 working days after a correctly filled Form 49B is submitted and the fee is paid. You can track progress on the Protean portal using the 14-digit acknowledgement number. The allotment letter is sent by email and post, and the TAN can then be quoted on TDS challans and returns.

Form 49B is the standard application form for allotment of a new TAN, filed online or offline. Corrections or changes to an existing TAN use the separate "Change/Correction in TAN data" form. Keep the PAN of the applicant entity handy, as PAN is mandatory in the Form 49B application.

Section 272BB imposes a penalty of Rs 10,000 for failing to apply for a TAN, failing to quote it, or quoting an incorrect TAN in challans, returns and certificates. Separately, you cannot file TDS returns without a TAN, your deductees will not get their credit in Form 26AS/AIS, and you can be treated as an assessee-in-default under Section 201 with monthly interest on the TDS involved.

A TAN can be flagged inactive if no TDS return is filed for a long period. Verify a TAN under "Know Your TAN / Verify TAN" on the income-tax portal (incometax.gov.in) by entering the number or the deductor name to see the status. If it shows inactive, file a pending TDS return or contact your jurisdictional TDS assessing officer.

Generally no. A single deductor needs only one TAN, used across all its TDS/TCS sections and returns nationwide. Large organisations sometimes obtain separate TANs for different branches or divisions to file returns independently, but duplicate TANs for the same office should be surrendered to avoid credit mismatches.

Quote the TAN on every TDS/TCS challan (Challan 281), every TDS return (24Q for salary, 26Q for non-salary, 27EQ for TCS) and every TDS certificate such as Form 16 and Form 16A. Quoting a wrong TAN, or omitting it, attracts the Section 272BB penalty and can break the deductee's Form 26AS credit.
