Have you got your account FATCA (foreign account tax compliance act) compliant? If you haven't then Monday could be a problem for you. Mutual fund investors, bank account holders and those who have invested in insurance schemes cannot operate their accounts, which were opened between July 1, 2014 and August 31, 2015, from May 1 if they are not compliant with FATCA.FATCA enables automatic exchange of financial information between India and the US. Indian financial institutions have to provide necessary information to Indian tax authorities, which will then be transmitted to the US. The inter-governmental agreement (IGA) with the US for implementing FATCA came into effect on August 31, 2015. Financial institutions were told to obtain self-certification and carry out due diligence procedure to determine the reasonableness of the self-certification in respect of all individual and entity accounts opened from July 1, 2014 to August 31, 2015.a) For bank account holdersIf you are a bank account holder and if you haven't given a self-certification till 30 April 2017, your account could be frozen, which would mean that the financial institution would prohibit the account holder from effecting any transaction with respect to such accounts.Investors and account holders have to provide a self-certification about 'tax residency' to their respective financial institutions for compliance with FATCA failing which the account will be blocked.b) For NPS account holdersIf you have opened a National Pension System (NPS) account on or after July 1, 2014 and it is being maintained with NSDL as Central Recordkeeping Agency for NPS, it will also get blocked unless you have submitted a self-certification of FATCA.You may have got an email, sms to download the self-certification form and submit the duly filled up physical self-certification (along with documentary evidence) to NSDL-CRA with signature.c) For mutual fund investorsAs per a Finance ministry release issued on April 11, 2017, all accounts/Folios with mutual funds, opened between July 1, 2014 and August 31, 2015 , must be FATCA compliant by April 30th, 2017.In case of non-compliance by this date these accounts will be blocked i.e. no financial transactions will be allowed in such non-compliant accounts after April 30 , 2017.
