TAN Registration — Complete Guide to Tax Deduction Account Number in India

TAN Registration Services in India

A Tax Deduction Account Number (TAN) is the ten-character alphanumeric identifier that every person who is required to deduct tax at source (TDS) or collect tax at source (TCS) must obtain under Section 203A of the Income Tax Act, 1961. TAN is to TDS compliance what PAN is to income tax compliance — it is the mandatory registration number without which no TDS return can be filed, no TDS certificate can be issued, and no TDS challan can be deposited. Every quarterly TDS return (Form 24Q, Form 26Q, Form 27Q, or Form 27EQ) must carry the deductor's valid TAN; every Form 16 and Form 16A issued to employees and payees must carry the deductor's TAN; and every TDS challan deposited with the bank must quote the TAN. Operating as a TDS deductor without a TAN is a penalty-attracting compliance failure under Section 272BB.

N D Savla & Associates, Chartered Accountants based in Mumbai, provides complete TAN registration services for companies, LLPs, partnership firms, trusts, and individuals required to deduct TDS. We handle the Form 49B application through the Protean eGov Technologies (NSDL) online platform, track the application, and receive the TAN on behalf of the client. We integrate TAN registration with TDS Return Filing services, ensuring that the newly registered deductor is set up on the income tax portal with the correct TAN credentials, has the TRACES (TDS Reconciliation Analysis and Correction Enabling System) account activated, and is ready to file their first quarterly TDS return by the due date. For new companies and LLPs, TAN registration is arranged simultaneously with PAN Registration as part of a complete new entity tax registration service.

TAN compliance is not a one-time registration — it is the foundation of an ongoing quarterly compliance cycle. Every quarter, a TAN holder must file TDS returns covering every deduction made during the quarter; correct errors in past returns through TRACES; download Form 16 and Form 16A certificates for payees and employees; and respond to any demand notices raised by the Income Tax Department for short deduction or non-deduction of TDS. The Income Tax Department matches every TDS credit in a payee's Form 26AS against the deductor's TDS return under the deductor's TAN. Mismatches in this matching process generate Section 143(1)(a) prima facie adjustment notices to payees who cannot claim TDS credits not filed by the deductor. All TAN-related filings and portal activities are done through the income tax portal at incometax.gov.in.

What Is TAN and Why Is It Required?

A Tax Deduction Account Number (TAN) is a unique ten-character alphanumeric identifier issued by the Income Tax Department to every person — individual, company, firm, government body, or any other entity — that is required to deduct tax at source (TDS) under the provisions of Chapter XVII-B of the Income Tax Act, 1961, or collect tax at source (TCS) under Chapter XVII-BB. The obligation to deduct or collect tax at source exists because the Income Tax Act places the responsibility of collecting income tax at the point of income payment, not just at the point of assessment. By requiring deductors to withhold a portion of every payment and deposit it with the government, the TDS mechanism ensures that tax revenue is collected continuously throughout the financial year rather than only upon assessment.

TAN serves as the deductor's unique identity in the TDS compliance ecosystem: it identifies who made the deduction, enables the payee to see the deducted amount in their Form 26AS (Annual Information Statement), allows the Income Tax Department to reconcile TDS deductions against deductors' returns, and provides the reference point for issuing demand notices when TDS is short-deducted or not deposited.

TAN vs PAN — Understanding the Key Difference

PAN and TAN serve different functions in the income tax system, though both use a similar 10-character format. PAN (Permanent Account Number) is the income tax identification number for every person as a TAXPAYER — it is used for filing income tax returns, quoting in financial transactions, claiming TDS credits, and correspondence with the Income Tax Department as a person paying income tax. TAN is the identification number for every person as a TAX DEDUCTOR — it is used specifically for all TDS-related activities: filing TDS returns, depositing TDS challans, issuing TDS certificates, and correspondence relating to TDS obligations.

A company needs BOTH a PAN and a TAN: the PAN for filing its annual income tax return and for its own tax payments; the TAN for deducting TDS on its employees' salaries, its vendors' payments, and its rent expenses, and filing the corresponding quarterly TDS returns. An individual who only earns salary and has no obligation to deduct TDS needs only a PAN, not a TAN. But an individual who starts a business that makes payments above TDS threshold amounts — salary to employees, rent above Rs. 2.4 lakh per year, professional fees above Rs. 30,000 per year — must obtain TAN.

Structure of a TAN Number

TAN follows a specific format:

• Characters 1–4 (four letters): The city/area code of the TDS circle that issued the TAN. For example, Mumbai TAN numbers begin with MUMB, Delhi with DELL, Chennai with CHEP, Kolkata with CALC, etc.
• Characters 5–9 (five digits): A sequential number in the series allotted by the Income Tax Department's TAN database
• Character 10 (one letter): An alphabetic check digit
• Example format: MUMB12345C (Mumbai deductor, sequential number 12345, check character C)

Who Must Obtain TAN Under Section 203A

Section 203A of the Income Tax Act, 1961 requires every person who is required to deduct tax at source under Chapter XVII-B, or collect tax at source under Chapter XVII-BB, to apply for and obtain a TAN. The persons most commonly required to obtain TAN include:

• All companies incorporated in India — companies deduct TDS on salary, professional fees, rent, contract payments, interest, and numerous other payments. TAN is mandatory from the date of incorporation.
• All LLPs and partnership firms that make payments above TDS threshold amounts
• HUFs that carry on business (subject to tax audit) and make payments above TDS thresholds
• Individuals and HUFs carrying on business or profession that are required to deduct TDS under any provision of Chapter XVII-B
• Government departments, local authorities, universities, and public sector entities that make payments subject to TDS
• Banks and financial institutions deducting TDS on interest under Section 194A
• Insurance companies deducting TDS on insurance commission under Section 194D
• Buyers of immovable property above Rs. 50 lakh under Section 194-IA (though Form 26QB allows PAN instead of TAN — see below)
• Trusts and charitable institutions paying salaries or making other TDS-liable payments from their funds

TAN Application — Form 49B

Form 49B is the prescribed form for applying for allotment of a new TAN. It is also used for correction or update of existing TAN data. The form is filed through the Protean eGov Technologies (formerly NSDL) TAN application portal, which is the authorised processor for TAN applications across India.

Information Required in Form 49B

Form 49B requires the following information about the TAN applicant:

• Status of applicant: Company / Individual / HUF / Firm / AOP / BOI / Local Authority / Artificial Juridical Person / Government
• Name of deductor/collector: Full legal name of the entity or individual applying for TAN
• Date of incorporation/formation (for entities) or date of birth (for individuals)
• Father's name (for individuals)
• Address of the principal place of business: Office/residence address where TAN-related correspondence will be received
• Contact details: Phone, email
• Existing PAN of the applicant (if available — PAN is not mandatory for TAN registration but linking PAN with TAN on the income tax portal is needed for e-filing TDS returns)
• Name and designation of the authorised signatory for companies and other entities
• Specification of the nature of deduction — the sections under which TDS will be deducted (salary, interest, rent, professional fees, etc.)

Documents Required for TAN Application

Form 49B does not require supporting documents for most applicants — the application is processed on the basis of the information provided in the form. However:

• For companies: The name in Form 49B should match the name in the Certificate of Incorporation exactly. Provide the CIN number.
• For individuals: Name should match PAN records. Provide PAN card copy as identity proof.
• For firms and LLPs: Name should match the partnership deed or LLP registration certificate.
• For trusts: Name should match the trust deed and registration certificate.
• For government deductors: Certification from the DDO (Drawing and Disbursing Officer) or the relevant government ministry/department.

Online TAN Application — Process and Fees

TAN applications are filed online through the Protean eGov Technologies portal at www.tin-nsdl.com or through the "Services" section on the income tax portal at incometax.gov.in. The online application process: (1) visit the Protean TAN application page; (2) select "New TAN" (or "Change Request" for corrections); (3) complete Form 49B online with all required details; (4) pay the application fee — currently Rs. 65.00 plus applicable GST for Indian addresses; (5) submit the application and note the 15-digit acknowledgement number; (6) the TAN is allotted by the Income Tax Department and communicated by email; (7) the physical TAN allotment letter is dispatched to the registered address within 7–15 working days. The TAN number is typically available within 3–5 working days of online application.

When TAN Is NOT Required — Special PAN-Based TDS Provisions

The general rule is that any person required to deduct TDS must have TAN. However, the Income Tax Act provides specific exceptions where TDS can be deducted and deposited using the deductor's PAN instead of a TAN, through dedicated online forms. These exceptions are designed to facilitate TDS compliance for individuals and one-off deductors who are not regular businesses with TDS obligations.

Section 194-IA — TDS on Purchase of Immovable Property (Form 26QB)

Section 194-IA requires a buyer of immovable property (other than agricultural land) to deduct TDS at 1% of the sale consideration if the sale consideration equals or exceeds Rs. 50 lakh. The TDS under Section 194-IA is deposited and the deduction is reported through Form 26QB — a special online form available on the income tax portal at incometax.gov.in. Form 26QB allows the buyer to quote their PAN (as buyer) and the seller's PAN in the form, deposit the TDS through the challan embedded in Form 26QB, and generate Form 16B (the TDS certificate for property purchase) — all without needing a TAN. The buyer who purchases property above Rs. 50 lakh must complete Form 26QB online, and a TAN is not required for this specific transaction.

Section 194-IB — TDS on Rent Payments by Individuals (Form 26QC)

Section 194-IB requires individual or HUF tenants (not subject to tax audit) who pay rent to a landlord exceeding Rs. 50,000 per month to deduct TDS at 5% on the annual rent. This TDS is deposited through Form 26QC — a special annual online form available on the income tax portal. Like Form 26QB, Form 26QC allows the tenant to use their own PAN without needing a TAN. Form 26QC must be filed within 30 days of the end of the financial year (by April 30) for all rent paid during the year. The corresponding TDS certificate is Form 16C.

Section 194M — TDS on Contractual or Professional Payments by Individuals (Form 26QD)

Section 194M requires individuals and HUFs (not subject to tax audit) who make payments to contractors or professionals above Rs. 50 lakh in a financial year to deduct TDS at 5%. These payments are reported through Form 26QD on the income tax portal, using PAN (not TAN). This provision captures large individual contractual and professional payments that otherwise escaped the TDS net when paid by individuals not subject to audit.

TDS and TCS Returns Filed Under TAN — Forms 24Q, 26Q, 27Q, and 27EQ

Every TAN holder who has made TDS deductions or TCS collections in a quarter must file the corresponding quarterly return on the income tax portal. There are four types of TDS/TCS returns, each covering different categories of deductions:

Form 24Q — Quarterly TDS Return for Salary

Form 24Q is the quarterly TDS return for TDS deducted on salary payments under Section 192 of the Income Tax Act. Every employer — company, firm, government department, or any other entity that pays salary — must file Form 24Q quarterly. Form 24Q contains: the employer's TAN and PAN; the employee details (PAN, name, salary paid in the quarter); TDS deducted on salary; and the challan details for TDS deposited. Form 24Q for the fourth quarter (January–March) is the most comprehensive, as it contains the full-year salary and deduction details for each employee, and forms the basis for generating Form 16 for employees. Our TDS Return Filing service covers complete quarterly Form 24Q preparation and filing for all employer clients.

Form 26Q — Quarterly TDS Return for Non-Salary Domestic Payments

Form 26Q is the quarterly TDS return for TDS deducted on all domestic (non-salary) payments to residents. This covers TDS under: Section 194A (interest from banks, NBFCs, deposits); Section 194C (payments to contractors); Section 194D (insurance commission); Section 194H (commission and brokerage); Section 194-I (rent); Section 194J (professional and technical fees); Section 194K (income in respect of units of mutual funds); Section 194LA (compensation for acquisition of immovable property); and numerous other sections. Form 26Q lists each payee (with PAN), each payment, the applicable TDS section, the TDS rate, and the TDS amount deducted. TDS credits visible in the payee's Form 26AS are sourced from the deductor's Form 26Q return.

Form 27Q — Quarterly TDS Return for Payments to Non-Residents

Form 27Q is the quarterly TDS return for TDS deducted on payments to non-residents and foreign companies under Section 195 and other related sections. Every Indian company that pays royalties, FTS, interest, dividends, management fees, or salary to non-residents must file Form 27Q. Form 27Q is closely linked with the Form 15CA/15CB compliance framework — each Form 15CA filing should correspond to an entry in the deductor's Form 27Q return. Inconsistencies between Form 15CA and Form 27Q are a common source of Income Tax Department queries.

Form 27EQ — Quarterly TCS Return

Form 27EQ is the quarterly return for Tax Collected at Source (TCS) under Chapter XVII-BB of the Income Tax Act. TCS is collected by sellers (as a percentage of the sale consideration) on specified goods and services: sale of scrap metal, sale of timber, sale of alcoholic liquor for human consumption, sale of tendu leaves, sale of forest produce, toll collection, parking lot collection, mining and quarrying, sale of motor vehicles above Rs. 10 lakh, remittances under LRS above Rs. 7 lakh, sale of overseas tour packages, and others. Every TCS collector must file Form 27EQ quarterly.

What to Do After Obtaining TAN — Setting Up TDS Compliance

1. Register on the Income Tax Portal With TAN
2. Activate TRACES Account — TRACES (TDS Reconciliation Analysis and Correction Enabling System at tdscpc.gov.in) is the Income Tax Department's platform for TDS return processing, correction, and certificate generation. Every TAN holder must register their TAN on TRACES to: download Form 16 and Form 16A TDS certificates for payees; view the TDS return filing status; submit correction statements for past return errors; check demand notices; and view the Form 26AS of deductors. TRACES activation typically requires filing the first TDS return to activate the account.
3. Set Up TDS Deduction Calendar
4. Maintain TDS Records — Maintain a TDS register that records: every payment made to every payee; the applicable TDS section and rate; the TDS amount deducted; the date of deduction; the challan number and date of deposit; and the acknowledgement number of the TDS return in which it was reported. These records support the Form 16/16A issuance process and are essential documentation in any assessment proceedings.
5. Issue TDS Certificates to Payees — Issue Form 16 (for salary TDS) to employees by June 15 of the assessment year, and Form 16A (for non-salary TDS) to payees within 15 days of the due date for the relevant quarterly TDS return. TDS certificates are downloaded from TRACES using the TAN login. Where a payee does not receive their Form 16A and the TDS is not reflecting in their Form 26AS, the error is in the deductor's TDS return — a correction statement must be filed through TRACES to correct the payee's PAN or deduction amount.

Consequences of Not Having TAN or Quoting Incorrect TAN

Section 272BB — Penalty for TAN Non-Compliance

Section 272BB of the Income Tax Act, 1961 prescribes a penalty of Rs. 10,000 for:

• Failure to apply for TAN when required to do so under Section 203A — i.e., operating as a TDS deductor without obtaining TAN
• Failure to quote TAN or quoting an incorrect TAN in TDS challans, TDS returns, TDS certificates, or any other document to which the TAN obligation applies

Interest Under Section 201(1A) for Delayed TDS Deposit

Where a TAN holder deducts TDS but fails to deposit it with the government by the due date (7th of the following month), interest under Section 201(1A) is levied at 1.5% per month (or part of a month) from the date of deduction to the date of actual deposit. This interest is computed on the TDS amount and is in addition to the TDS itself. Late deposit interest is a common compliance failure for entities that do not have a structured TDS calendar. A quarterly Tax Health Check for business clients includes verification that all TDS challans have been deposited within the prescribed timeline.

Disallowance Under Section 40(a)(ia) and 40(a)(i)

Where a person makes a payment to a resident on which TDS is required but has not been deducted (or has been deducted but not deposited by the due date for the TDS return), 30% of the expenditure is disallowed as a deduction in the payer's income tax return under Section 40(a)(ia). For payments to non-residents, the full 100% of the expenditure is disallowed under Section 40(a)(i) if TDS has not been deducted. These disallowances are identified in the Form 3CD tax audit report and reported to the Income Tax Department. Our Income Tax Audit engagement specifically reviews TDS compliance for all payees and flags any deduction that was made without corresponding TDS.

Impact on Payees — Missing TDS Credits in Form 26AS

When a deductor fails to file their quarterly TDS return, or files it with an incorrect PAN for the payee, the payee's TDS credit does not appear in their Form 26AS. The payee then cannot claim that TDS credit in their income tax return without supporting the claim with Form 16 or Form 16A. If the deductor's TDS return is incorrect, the payee may receive a Section 143(1)(a) prima facie adjustment notice from the CPC disallowing the TDS credit claimed. Timely and accurate TDS return filing is therefore not only the deductor's legal obligation but also a service to every payee who expects to see their TDS credit in Form 26AS.

TAN Registration for Specific Entity Types

Company TAN Registration — From Incorporation to First Return

Every company incorporated under the Companies Act, 2013 must obtain TAN before making its first TDS deduction — which typically happens within the first month of operations when the company starts paying salaries, professional fees, or rent. TAN registration for companies is arranged simultaneously with PAN registration and GST registration as part of the incorporation compliance setup. N D Savla & Associates provides complete new company registration compliance: Certificate of Incorporation assistance, PAN Registration, TAN Registration, GST Registration, and first advance tax computation — in a single, co-ordinated engagement.

LLP and Partnership Firm TAN

LLPs and partnership firms are frequent TDS deductors — they pay salaries, professional fees, rent, and contractor payments that are all subject to TDS. An LLP or firm without TAN cannot legally deduct and deposit TDS on these payments, making TAN registration one of the earliest compliance steps after LLP registration or firm constitution. For Business Tax Filing clients who are LLPs or firms, TAN compliance is integrated into the annual ITR-5 filing process.

Individual and HUF TAN

An individual is required to obtain TAN when their business or professional activities require them to deduct TDS under any provision of Chapter XVII-B of the Income Tax Act. Individuals who only use Form 26QB (property TDS) or Form 26QC (rent TDS) do not need TAN for those specific transactions. However, an individual with employees (paying salary above the exemption limit) must obtain TAN to deduct TDS under Section 192 and file Form 24Q quarterly. Similarly, a doctor or consultant who pays professional fees above Rs. 30,000 to another professional must obtain TAN and deduct TDS under Section 194J.

Government Deductors — DDO-Based TAN

Government departments, universities, public sector undertakings, and other government entities are TDS deductors for all payments made out of public funds. Government TAN registration follows a slightly different process: the Drawing and Disbursing Officer (DDO) of the department or unit obtains a TAN for that specific unit, and TDS is deposited through the government treasury system (NEFT/Book transfer) rather than through a regular bank challan. The Income Tax Department maintains a separate government deductor category in its TDS systems.

TAN Data Correction and Update

If the details associated with your TAN are incorrect — wrong name spelling, wrong address, or outdated contact information — you can request a correction through the Protean eGov Technologies TAN application system. The process is similar to TAN application: file a Change Request in Form 49B, marking the "Change" option (not "New TAN"), providing the existing TAN number, and specifying the corrected information.

Common TAN correction situations:

• Company name changed (after a merger, rebranding, or court-ordered name change): TAN should reflect the current legal name to ensure TDS certificates issued match the company's current identity
• Address changed (principal place of business relocated): Update TAN address to ensure all Income Tax Department notices and communications reach the current address
• Contact person changed: Update the designated contact for TAN-related correspondence
• Status change (e.g., a sole proprietor who converted to a Private Limited Company): A new TAN may be required for the company, and the old TAN should be surrendered if the proprietorship ceases

TAN Surrender and Cancellation

When a TAN holder ceases to have any TDS deduction obligations — because the business has been wound up, the entity has been dissolved, or the deductor no longer makes payments subject to TDS — the TAN should be formally surrendered to the Income Tax Department. Surrendering a TAN requires writing to the jurisdictional TDS Assessing Officer with: the TAN number; the reason for surrender; confirmation that all pending TDS returns have been filed; confirmation that all pending TDS demands have been settled; and the original TAN allotment letter (if available).

TAN surrender is important for wound-up companies and dissolved firms to prevent the Income Tax Department from generating compliance notices to the defunct entity. Ignoring a TAN without formally surrendering it means the Income Tax Department continues to expect quarterly TDS returns from that TAN, and non-filing attracts automated penalty proceedings.

History of TAN in India

The Origins of TDS and TAN

The concept of Tax Deduction at Source was introduced in the early history of Indian income tax law as a mechanism to ensure regular collection of income tax on payments to persons with substantial incomes. Initially, the TDS compliance framework did not have a standardised registration number for deductors. Deductors were identified by their PAN or by their taxpayer file number, and TDS reconciliation was largely manual. As TDS volumes grew with the expansion of the formal economy, the need for a dedicated identifier for tax deductors became apparent.

Introduction of TAN

TAN was introduced systematically with the Income Tax Department's computerisation programme in the 1990s and formalised through the insertion of Section 203A into the Income Tax Act. Section 203A made TAN mandatory for all persons required to deduct or collect tax at source, creating a separate, dedicated identifier for the TDS compliance ecosystem. The 10-character alphanumeric TAN format was designed to be structurally similar to PAN but distinct in its structure (city code in first 4 characters vs. jurisdiction code in PAN).

2003 Onwards — Protean (NSDL) as TAN Issuance Authority

The Income Tax Department outsourced TAN allotment and management to NSDL (now Protean eGov Technologies) in 2003, creating a standardised, online TAN application and issuance process. Online TAN application through the NSDL portal replaced the earlier practice of applying physically to the local Income Tax Department office, significantly reducing processing time and administrative burden.

TRACES — Transforming TDS Reconciliation

The launch of TRACES (TDS Reconciliation Analysis and Correction Enabling System) by the Income Tax Department transformed the TDS compliance landscape. TRACES enabled online Form 16 and Form 16A generation directly from TDS return data, online TDS correction statements, real-time TDS return processing status, and automated demand notices for TDS short-deductions. TRACES made the TAN the central access point for all post-return TDS activities.

Why Choose N D Savla & Associates for TAN Registration and TDS Compliance?

TAN registration itself is relatively straightforward.

We also set up the income tax portal login (PAN-based and TAN-based), TRACES registration, and first advance tax computation as part of the comprehensive new entity onboarding.

TDS Audit and Compliance Review

For existing TAN holders with ongoing TDS compliance, we conduct periodic TDS compliance reviews as part of our Tax Health Check service: verifying that all payments above TDS threshold have been subject to correct TDS; checking that TDS has been deposited within the due date (no Section 201(1A) interest exposure); ensuring that Form 26AS of payees correctly reflects all TDS deductions; and identifying any disallowances under Section 40(a)(ia) that may have arisen from TDS non-compliance.

Business Tax Integration

TDS compliance is inseparable from business income tax compliance. Our Business Tax Filing service integrates TAN compliance with the annual ITR filing — all TDS disallowances under Section 40(a)(ia) are identified and incorporated in the income computation, TDS credits are reconciled with Form 26AS, and TDS-related Form 3CD disclosures are correctly prepared in the Income Tax Audit report. Our Virtual CFO service manages the complete TDS calendar throughout the year for business clients.
