Accounts opened from July 2014 to August, 2015 will have to submit know your customer (KYC) details and their Aadhaar number to banks and financial institutions by April 30 and self-certify them to comply with FATCA regulations (Foreign Tax Compliance Act).

In case the account holders are unable to furnish details and provide self-certification by the new deadline, banks and financial institutions have the option of blocking the accounts.
Once the details are furnished they can operate the accounts. The provision applies to accounts which come under the ambit of FATCA regulations.

Banks and financial institutions were asked to obtain self-certification and carry out due diligence for all individual and entity accounts opened from July 1, 2014 to August 31, 2015 to comply with the Foreign Account Tax Compliance Act (FATCA) pact .

In July 2015, India and the US signed a tax information sharing agreement under a new US law, FATCA, aimed at bolstering efforts for automatic exchange of financial information.

The account holders may be informed that, in case self-certifications are not provided till April 30, 2017, the accounts would be blocked.
