Section 139AA of the Income-tax Act, 1961 as introduced by the Finance Act, 2017 provides for mandatory quoting of Aadhaar / Enrolment ID of Aadhaar application form, for filing of return of income and for making an application for allotment of Permanent Account Number with effect from 1st July, 2017.

It is clarified that such mandatory quoting of Aadhaar or Enrolment ID shall apply only to a person who is eligible to obtain Aadhaar number.

As per the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016, only a resident individual is entitled to obtain Aadhaar. Resident as per the said Act means an individual who has resided in India for a period or periods amounting in all to one hundred and eighty-two days or more in the twelve months immediately preceding the date of application for enrolment. Accordingly, the requirement to quote Aadhaar as per section 139AA of the Income-tax Act shall not apply to an individual who is not a resident as per the Aadhaar Act, 2016.

For any online update request, including updation of mobile number, resident should already have an active number registered with UIDAI where person can receive OTP SMS and authenticate himself/herself. Otherwise you would need to visit nearest UIDAI permanent enrollment centre.

Downloaded Aadhaar or e-Adhaar carries Name, Address, Gender, Photo and Date of Birth details of the Aadhaar holder in similar form as in Printed Aadhaar letter. The e-Aadhaar also contains date of Aadhaar generation & date of e-Aadhaar download. The downloaded Aadhaar or e-Aadhaar is a digitally signed document by UIDAI as per IT Act, 2000 which provides for legal recognition of electronic records with digital signatures.

Hence Downloaded Aadhaar /e-Aadhaar is a valid and secure electronic document which should be treated at par with printed Aadhaar letter.

Presently there is no Policy to give up Aadhaar. However Aadhaar holders can secure their Biometric Authentication as per need by locking or unlocking Biometrics using "Lock/Unlock Biometrics” functionality at UIDAI official website "resident.uidai.gov.in"
