Penalty for inaccurate transaction statements imposed; reporting financial institutions face per-account surcharge and recovery entitlement. The statutory scheme allows the prescribed income-tax authority to impose a fixed penalty on persons required to furnish statements of financial transactions or reportable accounts for providing inaccurate information, failing to correct inaccuracies within the specified time, or not complying with prescribed due diligence; prescribed reporting financial institutions face an additional per-account charge where inaccuracies result from account-holders, and may recover or retain that sum from those holders.
