PAN Card is an identity document bearing a ten-character alphanumeric Permanent Account Number issued by the Income Tax Department to every person required to file income tax returns or engage in specified financial transactions in India. Under Indian law, PAN is mandated by Section 139A of the Income Tax Act, 1961, and serves as the universal identifier for all tax-related activities.
Legal definition
Section 139A of the Income Tax Act, 1961 provides:
(1) Every person,—
(i) if his total income or the total income of any other person in respect of which he is assessable under this Act during any previous year exceeded the maximum amount which is not chargeable to income-tax; or
(ii) if he is carrying on any business or profession whose total sales, turnover or gross receipts are or is likely to exceed five lakh rupees in any previous year; or
(iii) who is required to furnish a return of income under section 139(4A),
and who has not been allotted a permanent account number, shall apply to the Assessing Officer for the allotment of a permanent account number.
Structure of PAN: PAN is a ten-character code in the format AAAAA0000A, where:
- Characters 1-3: Alphabetic series (AAA to ZZZ).
- Character 4: Status of the PAN holder — C (Company), P (Person/Individual), H (HUF), F (Firm), A (AOP), T (Trust), B (BOI), L (Local Authority), J (Artificial Juridical Person), G (Government).
- Character 5: First letter of the surname (for individuals) or name (for non-individuals).
- Characters 6-9: Sequential four-digit number (0001 to 9999).
- Character 10: Alphabetic check digit.
Mandatory quoting of PAN: Section 139A(5) read with Rule 114B of the Income Tax Rules, 1962 prescribes transactions where PAN must be quoted, including:
- Sale or purchase of immovable property valued at Rs 10 lakh or more.
- Sale or purchase of a motor vehicle.
- Opening a bank account (other than basic savings accounts).
- Applying for issue of a credit or debit card.
- Payment to hotels and restaurants against bills exceeding Rs 50,000.
- Purchase of mutual funds, debentures, or bonds exceeding Rs 50,000.
- Cash deposits exceeding Rs 50,000 in a single day with a bank.
- Payment exceeding Rs 50,000 per financial year for life insurance premium.
Aadhaar-PAN linkage: Section 139AA (inserted by the Finance Act, 2017) mandates that every person who has been allotted PAN and possesses an Aadhaar number must intimate the same in the prescribed form. Failure to link PAN with Aadhaar by the prescribed deadline renders the PAN inoperative.
How courts have interpreted this term
K.S. Puttaswamy v. Union of India (2019) 1 SCC 1 (Aadhaar judgment)
The Supreme Court, in the five-judge bench decision on Aadhaar's constitutionality, upheld Section 139AA requiring mandatory linkage of PAN with Aadhaar for income tax purposes. The Court held that the linkage serves a legitimate state interest in preventing tax evasion through duplicate or fraudulent PANs and that the requirement is a reasonable restriction that does not violate the fundamental right to privacy.
Binoy Viswam v. Union of India (2017) 7 SCC 59
The Supreme Court upheld the validity of Section 139AA, holding that Parliament has the legislative competence to mandate Aadhaar-PAN linkage. The Court observed that PAN is a document of identity for tax purposes and that requiring Aadhaar linkage strengthens the tax administration's ability to detect duplicate PANs and curb tax evasion.
Why this matters
PAN is the single most important financial identity document in India after Aadhaar. It is the backbone of the income tax system — every tax return, every TDS certificate, every advance tax payment, and every tax assessment references the PAN. Without a valid and operative PAN, individuals and entities face significant financial disabilities: TDS is deducted at higher rates under Section 206AA (20% or the applicable rate, whichever is higher), and key financial transactions become impossible.
For individuals and businesses, maintaining an operative PAN requires compliance with the Aadhaar-linkage mandate. As of the latest CBDT notifications, PANs that have not been linked with Aadhaar are rendered inoperative — meaning they cannot be used to file returns, process refunds, or complete prescribed financial transactions. The penalty for failing to apply for PAN when required is Rs 10,000 under Section 272B.
Practitioners should note the critical role PAN plays in information reporting. Financial institutions, property registrars, and mutual fund houses report all high-value transactions to the Income Tax Department through Annual Information Statements (AIS), linked to the taxpayer's PAN. This creates a comprehensive financial trail that the Department uses for scrutiny assessments and detection of undisclosed income.

Frequently asked questions
Is PAN mandatory for all Indians?
PAN is mandatory for every person whose total income exceeds the basic exemption limit, who carries on business with turnover exceeding five lakh rupees, or who enters into specified high-value financial transactions listed in Rule 114B. While not universally mandatory for every citizen, PAN is required for most significant financial activities.
What happens if PAN is not linked with Aadhaar?
Under Section 139AA and CBDT circulars, PAN becomes inoperative if not linked with Aadhaar by the prescribed deadline. An inoperative PAN cannot be used to file income tax returns, receive refunds, or complete prescribed financial transactions. TDS/TCS on payments to such persons is deducted at higher rates under Sections 206AA and 206CC. The PAN can be made operative again by paying a late fee of Rs 1,000 and completing the linkage.
Can a person have more than one PAN?
No. Section 139A(7) expressly prohibits any person from possessing more than one PAN. If a person inadvertently obtains multiple PANs, they must surrender the additional PANs using Form 49C. Possession of multiple PANs attracts a penalty of Rs 10,000 under Section 272B.
How do I apply for a PAN card?
Applications for PAN are made online through the NSDL (now Protean) or UTIITSL portals using Form 49A (for Indian citizens) or Form 49AA (for foreign citizens). The application requires identity proof, address proof, and date of birth proof. PAN is typically allotted within 15-20 working days. An instant e-PAN facility is also available for Aadhaar holders through the Income Tax e-filing portal.
