After the 31 March deadline to revalidate one’s KYC expired, a mutual fund investor’s KYC status broadly falls under one of three categories. That determines whether you can continue investing in just your existing funds, or new funds with other AMCs, or you get blocked from all transactions.
If your mutual fund KYC is not based on an officially valid document as specified by CAMS and KFintech, you will have to re-do your KYC by March 31, 2024. Failure to do this will mean you will not be allowed to do any MF transactions from April 1, 2024.
