The Central Board of Direct Taxes (CBDT) has set the deadline to link PAN with Aadhaar in India on December 31. Linking these two essential documents is mandatory to keep your PAN valid for filing income tax returns, carrying out banking transactions and meeting other financial requirements. With millions of taxpayers rushing to complete the process, understanding the quickest and most reliable way to link PAN and Aadhaar is crucial. Here’s your guide on the entire process.
Why PAN and Aadhaar Linking is Mandatory?
PAN (Permanent Account Number) is a 10-digit alphanumeric identification number issued by the Income Tax Department. It is required for filing tax returns, opening bank accounts, and conducting high-value financial transactions. Aadhaar, on the other hand, is a 12-digit unique identity number issued by UIDAI based on biometric and demographic details.
The government has mandated linking PAN with Aadhaar to curb tax evasion, eliminate fake PAN cards, and create a unified identity system.
If PAN and Aadhaar are not linked by December 31, your PAN will become inoperative. This can lead to rejection of income tax returns, delays or blocks in tax refunds, restrictions on bank transactions, higher TDS deductions, and difficulties in opening new financial accounts. Completing the linking process before the deadline ensures uninterrupted access to tax and financial services.
Step-by-Step Guide to Link PAN with Aadhaar Online
To link PAN and Aadhaar through the official portal, follow these steps –
- Visit the Income Tax e-Filing portal and use the Quick Links section to select the “Link Aadhaar” option.
- Enter your PAN, Aadhaar number, and name exactly as mentioned on the Aadhaar card.
- Verify your details and provide the mobile number registered with Aadhaar.
- Complete the OTP authentication sent to your registered mobile number.
- Once verified, your PAN and Aadhaar will be successfully linked.
Ensure that details such as name, date of birth, and gender match on both documents to avoid errors during the process.
How to Link PAN and Aadhaar via SMS?
For users who prefer offline methods, PAN-Aadhaar linking can also be done through SMS.
- Type UIDPAN <12-digit Aadhaar number> <10-digit PAN number> and send it from your registered mobile number to 567678 or 56161.
- You will receive a confirmation message once the linking is successful.
Before initiating the process, ensure that your name, date of birth, and gender are identical on both PAN and Aadhaar records. Your Aadhaar should be valid and your mobile number must be registered with Aadhaar to receive OTPs. Any discrepancies should be corrected in advance to avoid rejection.
