Penalty for inaccurate reporting requires reporting financial institutions to pay additional per-account fines and recover from account holders. Amendment creates a two-part penalty: the prescribed income-tax authority may direct a penalty for persons required to furnish statements under the reporting regime, and where a reporting financial institution files statements with inaccuracies caused by account holders, the authority shall direct an additional per-account penalty which the institution may recover from, or retain from moneys of, the relevant account holder(s).
