Ans. It is mandatory to quote your Aadhaar number and link it to your PAN for filing income tax returns. If you fail to link your Aadhaar with PAN by 30th June 2021, your PAN will become inoperative. If your PAN becomes inoperative, and you’re required to furnish, intimate, or quote your PAN under the Income Tax Act. It will be deemed that you have not furnished, intimated, or quoted your PAN (as the case may be).In such a case, you will be liable for all the consequences under the Act.

Ans. Correct your details in either PAN or Aadhaar database such that both have matching details. You can correct your PAN details on:

  • The TIN-NSDLwebsite, or
  • UTIITSL’s PANOnline

You can correct your Aadhaar details on the UIDAI website.

Q.6 Can I link my PAN and Aadhaar manually / offline?

Ans.  Yes, you can. Send an SMS from your mobile registered with Aadhaar to either of the PAN providers (NSDL or UTIITSL) at 567678 or 56161. Use this specific format in your SMS: UIDPAN <12-digit Aadhaar> <10-digit PAN>. Ensure there are spaces between UIDPAN, your Aadhaar number, and your PAN.

Q.7 What should I do if my PAN becomes inoperative?

Ans.  Your PAN will become inoperative if you do not link your Aadhaar with PAN by the prescribed date (presently 30th June 2021). If your PAN becomes inoperative, you will need to use the Link Aadhaar service on the e-Filing portal and link your Aadhaar. Your PAN will become operative after you link it.

    1. Adhar linked with PAN in the old portal. Should it be linked again in the new portal?
    2. Hope PAN will not be deactivated in the case of NRIs for not linking with Adhar? Information on this point is not explicit
