Turns out you have to link your bank account with Aadhaar after all. The Reserve Bank of India on Saturday stepped in to strike down news reports that claimed, quoting an RTI reply, it was not necessary to link the 12-digit biometric identification number with bank accounts, saying the directive remained in force under anti-money laundering rules.So, the December 31 deadline stays put for now. "The Reserve Bank clarifies that, in applicable cases, linkage of Aadhaar number to bank account is mandatory under the Prevention of Money-laundering (Maintenance of Records) Second Amendment Rules, 2017 published in the Official Gazette on June 1, 2017," the central bank said a notification.Earlier this year, the government had made it mandatory to link bank accounts with Aadhaar. Accounts that are not linked will cease to become operational, it said.To comply with the finance ministry directive, banks have already started asking for Aadhaar while opening new accounts and have been giving constant reminders to those who still haven't linked their accounts with the number.So considering that the rule to make Aadhaar mandatory for opening new accounts has already been enforced by banks, it would appear that as per current situation, existing account holders will not be given an exemption. Hence, if the government has its way, bank accounts not linked to Aadhaar will cease to become operational. Blocking of one's savings account will obviously lead to huge inconvenience and may well put a stop to your financial life.

According to the finance ministry directive, "Provided that in case client already having an account based relationship with reporting entities prior to date of this notification fails to submit the Aadhaar number and Permanent Account Number by 31st December, 2017, the said account shall cease to be operational till the time the Aadhaar number and Permanent Account Number is submitted by the client."
