What is Aadhaar Card?
Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) to every resident of India. It acts as a universal proof of identity and address and is now deeply integrated into India's tax and financial ecosystem. The name "Aadhaar" means "foundation" in Hindi, reflecting its role as the foundational identity document for Indian residents.
Eligibility for Aadhaar
- Any resident of India — citizen or non-citizen — who has resided in India for 182 or more days in the preceding 12 months is eligible.
- Children, including newborns, can be enrolled. Children under 5 receive a blue-coloured Baal Aadhaar which must be updated when they turn 5 and again at 15.
- Foreign nationals residing in India for the required period may also enrol.
Uses of Aadhaar in Taxation and Finance
- PAN-Aadhaar Linking: Mandatory under Section 139AA of the Income Tax Act, 1961. An unlinked PAN becomes inoperative, resulting in TDS at 20% (double the normal rate), inability to file ITR, and blocked refunds.
- ITR Filing: Aadhaar number must be quoted in every Income Tax Return filed after 1 July 2017.
- E-Verification of ITR: Returns can be verified instantly using Aadhaar OTP without sending a physical ITR-V to CPC Bengaluru.
- GST Registration: Aadhaar-based authentication is mandatory for new GST registrations since 2020. Biometric authentication may be required in certain states.
- KYC (Know Your Customer): Banks, insurance companies, mutual funds and stockbrokers accept Aadhaar for digital KYC under the eKYC process.
- Government Benefits: DBT (Direct Benefit Transfer) links Aadhaar to bank accounts for subsidy transfers — LPG subsidy, MNREGA wages, scholarships and pension payments.
NRI and Aadhaar
Non-Resident Indians (NRIs) are not required to link PAN with Aadhaar, provided they update their residential status as "Non-Resident" on the Income Tax e-filing portal. NRIs can apply for Aadhaar only after residing in India for 182+ days in the previous financial year.

- Enter PAN, Aadhaar number, and registered mobile number
- Pay the late fee of ₹1,000 via Challan No. ITNS 280 if linking after the deadline

⚠️ Consequence of Inoperative PAN: TDS is deducted at 20% instead of normal rates, no ITR can be filed, no refunds will be processed, and the PAN cannot be used for any financial transaction requiring PAN quotation.
Aadhaar Data Security
The UIDAI uses strong encryption and biometric data is not stored centrally in plain form. Residents can lock their biometrics using the UIDAI portal or mAadhaar app to prevent unauthorised biometric authentication.
