TAN Number India: How to Apply via Form 49B, Use in TDS Returns & Section 272BB Penalties

What is TAN and Why Does It Exist Separately From PAN?

A business already has a PAN. So why does the Income Tax Department insist on a second identifier just for TDS?

The answer lies in how TDS administration works at scale. When thousands of deductors deposit TDS into the government's account through OLTAS, and millions of deductees claim credit for that TDS in their ITRs, the department needs a way to track every deductor's account separately from their income-tax account. PAN serves the income-tax filing function; TAN serves the withholding-tax function.

Think of it this way: a manufacturing company has one PAN that governs its own income. The same company may have factories in three states, each running its own payroll and TDS operation. Each of those deducting offices can apply for a separate TAN, so that the TDS deducted at the Pune factory does not get mixed up with the TDS deducted at the Chennai factory in the department's records. Centralised deduction is also allowed under a single TAN, but the point stands: TAN is a deductor-level identifier, not a taxpayer-level identifier.

Under Section 203A of the Income Tax Act, 1961, quoting a TAN is mandatory on:

• Every TDS challan (ITNS 281)
• Every TDS/TCS return (24Q, 26Q, 27Q, 27EQ)
• Every TDS certificate (Form 16, Form 16A, Form 27D)
• Every statement of tax deducted/collected at source filed with the department
• Any document as may be prescribed

A deductor who pays salaries, professional fees, rent, and contractor charges out of the same entity uses the same TAN for all payments. Separate TANs per payment type are not necessary and should not be applied for.

Who Must Apply for a TAN

The obligation arises the moment you make or expect to make a payment covered by any TDS section. Common examples:

The threshold that triggers TDS is separate from the TAN obligation. You should apply for TAN before you cross the payment threshold, not after. A business that expects to pay a contractor Rs 50,000 in the year should have the TAN in hand before the first payment.

Who does NOT need a TAN:

• Individual buyers deducting TDS under Section 194-IA (property purchase above Rs 50 lakh) use Form 26QB, which works without a TAN.
• Individual tenants deducting TDS under Section 194-IB (rent above Rs 50,000 per month) use Form 26QC, which also works without a TAN.
• These are specific legislative carve-outs for individuals who are otherwise not in the business of deducting tax. Every other deductor category requires TAN.

Structure of a TAN

A TAN follows the format: AAAA99999A

• First four characters: alphabetic, indicating the city or state of issue
• Next five characters: numeric, the unique sequence number
• Last character: alphabetic, a check digit

Example: MUMB12345A would indicate a TAN issued through the Mumbai jurisdiction. The first four letters are drawn from the city/state code assigned by the Income Tax Department to each PROTEAN processing centre.

This structure matters when you are entering TAN in OLTAS challans or TDS returns. The system validates the format at entry. A TAN typed incorrectly (or a PAN mistakenly entered where TAN should go) will fail the challan upload validation.

Step-by-Step: Applying for TAN Online via Form 49B

Step 1: Go to the PROTEAN TAN Application Portal

Open tin.tin.nsdl.com/tan/form49B.html in a browser. PROTEAN eGov Technologies (formerly NSDL e-Governance Infrastructure Limited) is the authorised agency for TAN applications. Do not use any third-party site that charges above the standard Rs 65 fee; the official application is straightforward.

Step 2: Select Application Type

You will see two options:

• New TAN: For a deductor applying for the first time.
• Changes or Correction in TAN Data: For updating name, address, contact details, or for surrendering a duplicate TAN.

For a first application, select New TAN.

Step 3: Fill in Form 49B

The form collects the following information. Have these details ready before you start:

Double-check the name field. If the PAN was applied in a short or abbreviated form (e.g., "XYZ Pvt Ltd" vs "XYZ Private Limited"), use the name exactly as on the PAN. The TAN system matches against the PAN database.

Step 4: Pay the Application Fee

The application fee is Rs 65 plus applicable GST (currently Rs 65 + 18% GST = Rs 76.70 total, though the portal shows the amount at checkout). Payment options include:

• Net banking (major banks covered)
• Debit card / credit card
• Demand draft in favour of "NSDL-TIN"

For online applications, net banking or card payment is the norm. The payment confirmation page generates an acknowledgement number. Save it.

Step 5: Download and Submit the Acknowledgement (for Physical Verification)

After online submission, the portal generates a 15-digit acknowledgement number and an acknowledgement slip. For applications submitted online without a digital signature:

1. Print the acknowledgement slip.
2. Affix a photograph (if the deductor is an individual or HUF).
3. Attach a copy of the relevant proof (Certificate of Incorporation for company, Partnership Deed for firm, PAN card for individual).
4. Sign across the photo (for individual/HUF applicants).
5. Send the physical packet to the PROTEAN address printed on the acknowledgement slip, within 15 days of online submission.

For companies and other entities that use a DSC (Digital Signature Certificate) on the application, physical submission is not required.

Step 6: Track and Receive TAN

Track the status using the 15-digit acknowledgement number at tin.tin.nsdl.com/tan/TanStatus.html. Processing time is typically 7 to 15 working days after physical documents are received (or from online submission if DSC is used).

The TAN is sent to the registered email and by post to the address on the application. Once received, verify that the name and address printed on the TAN allotment letter exactly match your records. Any discrepancy should be corrected immediately using the Change/Correction form before you start using the TAN in returns.

Using TAN in OLTAS Challans (ITNS 281)

OLTAS (Online Tax Accounting System) is the mechanism for depositing TDS with the government. Every TDS payment goes through a challan. For TDS, the relevant challan is ITNS 281, filed at the authorised bank or through the income tax e-filing portal's online challan payment facility.

ITNS 281 has the following TAN-related requirements:

One challan can cover TDS under multiple sections as long as the deductor TAN is the same. The bank generates a BSR Code and a Challan Serial Number on payment. These two fields, combined with the date of deposit and amount, are the challan reference that must be reported in the TDS return. Losing the challan receipt creates reconciliation problems during return filing, so store it immediately in a dedicated folder.

Due dates for ITNS 281 deposit:

Late deposit attracts interest at 1.5% per month (or part of month) under Section 201(1A).

Using TAN in Quarterly TDS Returns

Once you have deposited TDS through ITNS 281, you must report it in a quarterly TDS return filed on the Income Tax e-filing portal. The return links each payment made by the deductor (via challan) to each deductee (by PAN) and to the amount deducted.

For Q1, Q2, and Q3, the deadline is the 31st of the month following the end of the quarter.

The TAN entered in the return must exactly match the TAN used in the ITNS 281 challan. A mismatch between the challan TAN and the return TAN creates a broken link in the TRACES system, and the deductee cannot see the TDS credit in Form 26AS or AIS. This is one of the most common causes of TDS credit disputes.

What the TDS Return Contains

For each payment entry in Form 26Q or 24Q:

• TAN of deductor
• PAN of deductee
• Amount paid
• TDS deducted
• Challan BSR code, serial number, deposit date
• Section under which TDS was deducted
• Rate of deduction

The TRACES system processes this data and populates Form 26AS and AIS for every deductee. When a deductee files their ITR and claims TDS credit, the department cross-checks it against your return. If you filed the return with the wrong TAN, the deductee's credit will not match, and the deductee will receive a demand.

Section 272BB: Penalties for TAN Non-Compliance

Section 272BB of the Income Tax Act imposes two distinct penalties:

Penalty 1: Failure to apply for TAN

If a deductor makes TDS payments without having obtained a TAN, the Assessing Officer can levy a penalty of Rs 10,000. This penalty can be imposed for each year or period of non-compliance, not just once.

Penalty 2: Quoting incorrect TAN

If a deductor quotes a TAN other than their own on a challan, TDS return, certificate, or any document where TAN is required, the penalty is again Rs 10,000.

These penalties are in addition to, not instead of:

• Interest under Section 201(1A) for late deposit of TDS (1.5% per month)
• Late fee under Section 234E for late filing of TDS return (Rs 200 per day, up to the TDS amount)
• Penalty under Section 271C for failure to deduct TDS at all (equal to the TDS amount)

A business that deducts TDS but uses the wrong TAN, files returns late, and then gets a notice, faces all four consequences simultaneously. The TAN penalty specifically is meant to catch the case where a deductor is operating informally without registration.

Compounding: The Income Tax Department has a compounding facility for penalty proceedings, and TAN-related violations are generally compoundable on payment of the penalty amount. However, compounding requires a formal application and is not automatic.

Common TAN Application Mistakes and How to Handle Them

Mistake 1: Name Mismatch with PAN

The most frequent rejection. If the entity name on PAN reads "Acme Trading Private Limited" but the Form 49B is filled as "Acme Trading Pvt Ltd", PROTEAN will reject or hold the application for clarification. Always copy the name verbatim from the PAN card or the income tax portal's e-filing dashboard.

Mistake 2: Applying for Multiple TANs

This happens when the first application is submitted but the TAN takes time to arrive, so the person applies again thinking the first one was lost. This creates a duplicate. The Income Tax Act prohibits holding more than one TAN. If you discover this, see the Duplicate TAN section below.

Mistake 3: Wrong Jurisdiction

The jurisdiction (the first four letters of the TAN) is assigned based on the address entered in Form 49B. If you enter a branch address in Mumbai but the entity's principal office is in Hyderabad, and later file TDS returns from the Hyderabad PAN, there can be a mismatch in assessing officer jurisdiction. Apply under the jurisdiction where the principal place of business is situated unless you are applying for a branch-specific TAN.

Mistake 4: Using PAN Where TAN Is Required

PAN and TAN are different 10-character identifiers. PAN follows the format AAAAA9999A (five alpha, four numeric, one alpha). TAN follows AAAA99999A (four alpha, five numeric, one alpha). OLTAS challan validation and TRACES will reject an entry where PAN is typed into the TAN field, but this is still a common manual data-entry error in offline returns.

Mistake 5: Not Linking TAN to the Correct PAN

The TAN application links to the PAN you provide on Form 49B. If the company later changes its PAN (rare but possible after certain corporate restructurings), the old TAN needs to be updated to reflect the new PAN. This must be done through the Change/Correction form at PROTEAN, not through the income tax portal.

How to Correct a Wrong TAN or Surrender a Duplicate

Corrections and surrenders are handled through the same PROTEAN portal, using the "Changes or Correction in TAN Data" form.

Correcting TAN Details

If the name, address, email, or phone on your existing TAN record is incorrect:

1. Go to tin.tin.nsdl.com/tan/TanUpdate.html
2. Select "Changes or Correction in TAN Data"
3. Enter your existing TAN and verify the current details
4. Correct the fields that need updating
5. Pay the Rs 65 (plus GST) correction fee
6. Submit supporting documents (fresh Certificate of Incorporation, updated address proof, etc.)

Surrendering a Duplicate TAN

If you inadvertently hold two TANs:

1. Identify which TAN has been used in past challans and TDS returns. That is the one to retain.
2. Use the unused TAN as the one to surrender.
3. Submit the "Changes or Correction in TAN Data" form, selecting the "Surrender" option for the TAN to be deactivated.
4. PROTEAN deactivates the surrendered TAN and sends a confirmation.
5. Inform your bank(s) and accounting team to stop using the surrendered TAN immediately.

If TDS has already been deposited under the wrong (now-surrendered) TAN, file a correction statement through TRACES to shift those transactions to the correct TAN. This process requires the login credentials of both TANs in TRACES.

Never ignore a duplicate TAN. The department's system flags deductors with more than one active TAN, and the Assessing Officer can treat it as a Section 272BB violation (quoting incorrect TAN) even if it was unintentional.

TAN vs. PAN: Quick Comparison

Checklist: TAN Compliance for a Newly Registered Business

If you have just incorporated a company or registered a partnership firm and expect to pay salaries or engage contractors in the first year, work through this list:

• Apply for TAN via Form 49B on PROTEAN before the first payroll or contractor payment
• Verify the TAN allotment letter on arrival: name and address must match PAN
• Register the TAN on the Income Tax e-filing portal (e-filing.incometax.gov.in) under "Register as Deductor"
• Register on TRACES (tdscpc.gov.in) using TAN login for downloading 26AS, consolidated TDS files, and Form 16/16A generation
• Maintain the TAN prominently in your accounting software's TDS module so it auto-fills in ITNS 281 and return files
• File ITNS 281 within the due date after every month of TDS deduction
• File quarterly TDS returns (24Q/26Q) within the due dates
• Issue Form 16 to employees by June 15 and Form 16A to other deductees within 15 days of the due date for filing the quarterly return

FAQs on TAN Application and Compliance

Frequently Asked Questions

Is a TAN mandatory for a sole proprietor or an individual who pays a contractor?

Yes, if the contractor payments exceed Rs 30,000 per contract or Rs 1,00,000 in aggregate in a financial year. Section 194C applies to 'any person' responsible for payment, including individuals and HUFs whose books of accounts are required to be audited under Section 44AB in the preceding financial year. If the individual does not meet the audit threshold, Section 194C does not apply, and no TAN is needed for that specific payment. However, if the same individual pays rent above Rs 2,40,000 per year (Section 194-I, for non-individuals; note that Section 194-IB is for individuals/HUFs paying rent above Rs 50,000 per month and uses Form 26QC without TAN), consult a CA on which provision applies.

Can I use my company's PAN instead of a TAN on a TDS challan?

No. The TAN and PAN fields on ITNS 281 are separate and serve different purposes. Entering PAN in the TAN field will cause the challan to fail format validation. Even if it passes (in older offline systems), the OLTAS database links TDS credits to the TAN, not PAN. A challan filed without a valid TAN will not create credits in deductees' Form 26AS.

How long does it take to get a TAN after applying online?

After PROTEAN receives the physical acknowledgement (for applications without DSC), the TAN is typically allotted within 7 to 15 working days. For DSC-signed online submissions, the timeline is similar or slightly faster. The TAN is sent to the registered email first, so you may start using it before the physical letter arrives, as long as you have the official email confirmation from PROTEAN.

What if I deducted TDS before getting a TAN? Do I have to pay the Section 272BB penalty?

The Section 272BB penalty is at the Assessing Officer's discretion in a show-cause proceeding. If you apply for TAN before filing the first TDS return and deposit the TDS with the correct TAN, the practical risk is low. The penalty is most commonly levied when a business operates without TAN for multiple quarters and an officer notices the discrepancy during a scrutiny. Apply as soon as you know you will be making TDS-liable payments.

I received two TAN allotment letters. What do I do?

Stop using both TANs immediately. Check which one (if either) has been used in OLTAS challans or TDS returns by logging into TRACES. The TAN with existing transactions is the one to retain. Submit the Change/Correction form on PROTEAN to surrender the unused TAN. If both have been used, you will need to file correction TDS statements via TRACES to consolidate all transactions under one TAN before surrendering the other.

Does a branch office need a separate TAN from the head office?

Not necessarily. A single TAN can be used for all of an entity's TDS activities across India. However, large organisations often obtain branch-specific TANs to localise payroll and vendor payments by jurisdiction. This is allowed, and the Income Tax Act permits separate TANs for separate branches. The restriction is on accidentally holding multiple TANs for the same office or operation, not on intentionally segregating by branch.

How do I update the address on my TAN if we moved offices?

Use the 'Changes or Correction in TAN Data' facility on PROTEAN (tin.tin.nsdl.com). Fill in the correction form, pay the Rs 65 fee, and submit proof of the new address (utility bill, rent agreement, or registration certificate). The updated TAN allotment letter will be sent to the new address. Until the correction is processed, the old address remains on file, but this does not affect the validity of TDS challans or returns that correctly quote the TAN.

Is a separate TAN needed for TCS (Tax Collected at Source)?

No. The same TAN used for TDS is used for TCS. The TCS returns (Form 27EQ) are filed under the same TAN, and ITNS 281 covers both TDS and TCS payments. The section code in the challan distinguishes TDS from TCS transactions.
