Centre has made it compulsory to link Aadhaar with a number of essentials like Income Tax returns, PAN, and much more. Notably, all mobile numbers that are not linked to Aadhaar will be deactivated after February 28, as per IANS. The government is going ahead to link Aadhaar with mobile SIM cards, the agency further added. Aadhaar numbers have to be submitted in order to avail various social security schemes. As per NDTV, whether linking the Aadhaar with mobile SIM cards, PAN or bank account numbers, there are deadlines in each case. Below are four deadlines that you need to meet to link Aadhaar with a number of documents:

1) Deadline to link Aadhaar with PAN

The Central Board of Direct Taxes (CBDT) had extended the last date to link Aadhar with PAN in August to December 31, 2017. Earlier deadline was August 31. It is mandatory to link Aadhaar-PAN in order to process the income tax returns (ITRs) for assessment year 2017-18, the income tax department said. “If this linking (PAN-Aadhaar) is skipped, the return could be considered invalid and the person may have to file it again which shall be considered belated and may attract penalty, interest and other consequences like disallowances for losses,” says Sandeep Sehgal, director of tax and regulatory at Ashok Maheshwary & Associates LLP, was quoted as saying by NDTV.

2) Deadline to link Aadhaar with mobile number

Mobile numbers that are not linked with Aadhaar will be deactivated after February next year. As per IANS, a number of telecom companies have already started sending alerts to customers to link their Aadhaar numbers with Mobile numbers. These companies had earlier urged their customers to start the process of linking Aadhaar card numbers with mobile numbers, NDTV added.

3) Deadline to submit Aadhaar details with banks

As per NDTV, Centre has made it compulsory for all banks  to provide Aadhaar details of clients in Know your Customer (KYC) document. This document provides all details to authenticate the identity of account holders. Those taking loans from banks are also needed to file their Aadhaar details. In case an account holder fails to link his bank account by December 31, the account may also become non-operational.

4) Deadline to provide Aadhaar details to get social security schemes

Aadhaar number has to be provided for all social security schemes by December 31. Those who want to avail pension, LPG cylinders or government scholarships, need to provide his or her Aadhaar card details, NDTV added.
