PFICs and Foreign Investments

Americans in the UK Need to Avoid this Catch-22 Investment TrapThe U.S. Passive Foreign Investment Company (PFIC) tax regime raises high hurdles for Americans in the United Kingdom to invest wisely and tax efficiently. This is because the United Kingdom has a parallel system of punitive taxation of non-UK funds. This investment “Catch-22” can be successfully navigated by investing in efficient U.S. exchange traded funds that are also so-called UK “reporting funds.” Most importantly, the new U.S. FATCA legislation makes this once easily ignored tax issue critical for all American investors living in the United Kingdom.
