PAN and TAN Registration for a Company

Updated 11 October 2026 · Fact-checked

PAN (Permanent Account Number) is a 10-character alphanumeric identity number for a taxpayer. TAN (Tax Deduction and Collection Account Number) is a 10-character number for a person who deducts or collects tax at source. A company needs a PAN to file returns and a TAN to deduct TDS. Apply online and quote each number where the law requires.

Understand PAN and TAN Registration

Every business that deals with the tax department needs a way to be identified. PAN and TAN are those identifiers. They look similar, but they serve different purposes, and exam questions often test exactly this difference.

PAN identifies a person as a taxpayer. It is a 10-character alphanumeric number issued by the Income Tax Department. A company, firm, LLP, individual or trust can each hold one. It links your tax payments, returns, high-value transactions and refunds to a single record. A company usually obtains its PAN at incorporation. In the SPICe+ incorporation form, the PAN is allotted along with the incorporation certificate, so a separate application is normally not needed.

TAN identifies a person who is responsible for deducting tax at source (TDS) or collecting tax at source (TCS). It is also a 10-character alphanumeric number. If a company pays salary, rent, professional fees, interest or contractor payments above the prescribed limits, it must deduct tax and deposit it with the government. To do that, it must hold a TAN. In the same SPICe+ route, TAN is also allotted at incorporation.

Why both matter. PAN is about the tax the company itself owes. TAN is about tax the company deducts on behalf of others. A company with no employees or deductible payments may not use TAN much, but any company that deducts TDS cannot do without it.

For the June 2027 session, the tax law is the Income-tax Act, 2025. Do not rely on section numbers from the old 1961 Act in your answer unless the question asks for them. Focus on the concept, who must obtain it, how to apply and where to quote it.

Key rules to remember

PAN format: 10 characters: 5 letters + 4 digits + 1 letter; For example, AAACB1234C. The fourth character shows the holder's status, and a company's PAN carries the letter C there. The fifth character is the first letter of the entity's name, or the surname for an individual. In the example, B would be the first letter of the company's name.
TAN format: 10 characters: 4 letters + 5 digits + 1 letter; For example, DELA12345B. The first three letters indicate the jurisdiction or city code, and the fourth letter is the initial of the deductor's name.
Who needs PAN: Taxpayers, persons required to file a return, and persons carrying out specified transactions; A company needs PAN to file its return, pay tax and enter specified high-value transactions.
Who needs TAN: Every person who deducts or collects tax at source; TAN is needed to deposit TDS or TCS, file TDS or TCS statements and issue TDS certificates.
Where TAN must be quoted: TDS or TCS returns, tax payment challans, TDS or TCS certificates; PAN is not a substitute for TAN in these documents.
Applying for a company: At incorporation: SPICe+ gives PAN and TAN. After incorporation: apply online; Check the latest procedure notified by the tax department for any change.

How to solve PAN and TAN Registration questions

Use this approach for any question on PAN and TAN, whether it is a short note, a difference or a case problem.

1Identify what the question asks: meaning, difference, who needs it, how to apply or where to quote it.
2State the full forms and meaning of PAN and TAN in one line each.
3Identify the person in the facts. Ask whether it is a taxpayer, a person deducting tax, or both.
4Link the person to the number. Taxpayer or return filer needs PAN. A person deducting or collecting tax needs TAN.
5Describe the application route. For a new company, mention allotment through SPICe+. For an existing one, mention the online application.
6List where each number must be quoted, such as returns, challans, TDS certificates and prescribed transactions.
7Close with a clear conclusion that answers the exact question in one sentence.

Quickest way: Deduct or pay: the two-question test

When to use it: Use it when a case gives you facts about a company and asks which number it needs.

Ask: does the company owe or report its own tax? If yes, PAN.
Ask: does the company deduct or collect tax from payments to others? If yes, TAN.
If both are yes, the answer is both, and say so.
For a newly incorporated company, add that SPICe+ allots PAN and TAN along with incorporation.
Write one line on where each number is quoted and stop.

Common mistakes in PAN and TAN Registration

Saying TAN can be used in place of PAN when filing a return.
Both are 10-character numbers and the names sound alike.
Fix: Remember that PAN is for the taxpayer and TAN is only for the person deducting or collecting tax. They are not interchangeable.
Quoting PAN on a TDS challan or TDS certificate as the deductor's number.
Students assume one number is enough for everything.
Fix: Quote TAN as the deductor's identity in TDS or TCS documents. The deductee's PAN is also quoted, but separately.
Writing that a company must apply separately for PAN after incorporation in every case.
Students ignore the integrated SPICe+ process.
Fix: Say that PAN and TAN are generally allotted through SPICe+ at incorporation. A separate application arises only when this has not happened.
Mixing up the formats of PAN and TAN.
Both have 10 characters and the letter-digit pattern is hard to remember.
Fix: PAN is 5 letters, 4 digits, 1 letter. TAN is 4 letters, 5 digits, 1 letter.
Saying every company must have a TAN regardless of its activities.
Students overstate the rule when memorising.
Fix: State that TAN is mandatory for any person who deducts or collects tax at source, which in practice covers most operating companies.
Quoting old 1961 Act section numbers from memory for the June 2027 session.
Older notes and books still use the earlier numbering.
Fix: Refer to the Income-tax Act, 2025 and give a section number only if you are sure of it. Otherwise explain the rule in words.

Worked examples

Example 1

Bharat Textiles Private Limited has just been incorporated in Surat. It will employ 40 people and pay monthly salaries and professional fees. Advise which numbers it needs and how it obtains them.

Show the solution

Provision: PAN identifies a taxpayer, and TAN identifies a person who deducts or collects tax at source.
Facts: the company is a new taxpayer and it will pay salaries and professional fees from which tax must be deducted.
Analysis: as a taxpayer it needs PAN. As a payer who deducts TDS it needs TAN.
Process: both are generally allotted through the SPICe+ incorporation form, so a separate application is usually not required.
Quoting: PAN goes on its returns and specified transactions. TAN goes on TDS payment challans, TDS statements and TDS certificates.

Answer: Bharat Textiles needs both PAN and TAN. They are normally allotted along with incorporation through SPICe+, and each must be quoted in the documents described above.

Example 2

Distinguish between PAN and TAN.

Show the solution

Meaning: PAN is the Permanent Account Number of a taxpayer. TAN is the Tax Deduction and Collection Account Number of a person who deducts or collects tax.
Purpose: PAN identifies the taxpayer for returns, payments and refunds. TAN identifies the deductor or collector for TDS and TCS compliance.
Who needs it: PAN is needed by taxpayers and by persons entering specified transactions. TAN is needed by persons who must deduct or collect tax at source.
Format: PAN has 5 letters, 4 digits and 1 letter. TAN has 4 letters, 5 digits and 1 letter.
Quoting: PAN is quoted in returns and specified transactions. TAN is quoted in TDS or TCS returns, challans and certificates.

Answer: PAN identifies a person as a taxpayer, while TAN identifies a person as a deductor or collector of tax at source. They differ in purpose, who needs them, format and where they are quoted.

Exam tips

Questions are often short notes or differences. Learn a four-point comparison: meaning, purpose, format, where quoted.
Always link the number to the person in the facts. Write which role the company plays: taxpayer, deductor, or both.
Mention SPICe+ when the case involves a newly incorporated company.
For the June 2027 session, cite the Income-tax Act, 2025, and avoid old section numbers unless you are sure.
Finish with a one-line conclusion so the examiner sees a clear answer.
