IS THERE BANKING SECRECY IN THE US?

Banking secrecy is applied in the USA.
However, we do not advise using a company in the USA to avoid reporting income in your country of tax residence. The U.S. tax office has announced that it will not allow the U.S. system to be used to avoid reporting income in another country by a foreign tax resident. It is preferable to pay a minimum of tax in the US and then to use tax treaties that allow for legal limits on total taxation.
