There is definitely an NBFC requirement, but unless you reach out to RBI for something or RBI reaches out to you for something or if your auditor doesn’t file the exception report to RBI (which is required if financial income is more than 50%), then you may not get spotted.

Also like @TAXIQ.IN said, whenever RBI spots and asks for registration, they will provide time.

By the way, if this really has to be done, maybe partnership firm is a better option.
