Generally, a recalcitrant account holder is any account holder that (1) fails to comply with reasonable requests for information necessary to determine if the account is a United States account; (2) fails to provide the name, address, and TIN of each “specified United States person” and each substantial United States owner of a United States owned foreign entity; or (3) fails to provide a waiver of any foreign law that would prevent a foreign financial institution from reporting information required under FATCA.
