The Deadline is once again extended by three months up to March 31, 2020. Failing to do so, your ITR (income tax return) will get rejected and the PAN card will become inoperative.
The due date for linking of PAN with Aadhaar as specified under sub-section 2 of Section 139AA of the Income-tax Act,1961 has been extended from 31st December, 2019 to 31st March, 2020.— Income Tax India (@IncomeTaxIndia) December 30, 2019
Notification no.107 of 2019 dated 30/12/2019 issued by CBDT.
Linking via Income Tax Department website
To begin with, you need to first register on the Income Tax e-filing portal (incometaxindiaefiling.gov.in), in case you are not already registered. If you already have an account, sign in to the portal with your ID, password, and date of birth, a pop-up window will appear, assisting you with the process of linking your Aadhaar with PAN.
In case you don’t see the window, you can go to Profile Setting -> Link Aadhaar. Simply verify the details on the screen, fill in your Aadhaar number, and click on ‘Link Aadhaar’ button. An OTP will be sent on your mobile number for authentication, and if your details match, the linking will be successfully done.
Linking using SMS
You can either send an SMS to 567678 or 56161. It is worth mentioning that linking of the two will only be successful if both Aadhaar and PAN card are registered with the same name.
To link using SMS, type UIDPAN followed by your 12-digit Aadhaar number, and after a space type the 10-digit PAN number. Now send the text to 567678 or 56161. For example, UIDPAN 123456781234 ANWP1234AN, where 123456781234 is the Aadhaar number and ANWP1234AN is the PAN number.
Do note that this SMS has to be sent using your registered mobile number. Once the linking is successful, you will be notified about the same with an SMS.
