"公民海外資產是要上稅的" It is not true.
By new regulations on offshore accounts reporting, US citizens'asset outside US jurisdiction must be reported to IRS, but not taxed AS LONG AS the assets remain outside US jurisdiction. They would, however, be treated income and subject to income tax if they are brought into US.
This increasingly become problematic to US citizens and economy. Many big corporations like GE have huge overseas business that earned a lot of money outside US. But they are all reluctant to bring those money back into US because of taxes.
As to reporting rule, failure to disclose overseas acccunts will result in severe penalty and fines.
