FATCA and extra-territorial taxation
Generally the question of whether one is a “U.S. person” (citizen, Green Card Holder, resident, substantial presence test) is determined under U.S. law. FATCA has the effect of enforcing the taxation of “U.S. persons” who reside outside the U.S. By changing the definition of “U.S.
person”, the U.S. can increase the number of “U.S. persons” residing in other countries. FATCA – by identifying “U.S. persons” – is the enforcer of extra-territorial taxation. The combined effect of “U.S. person” taxation and FATCA is that the U.S. can increase or decrease its tax base in other countries. If more people are deemed to be U.S. persons the tax base will increase. The FATCA rules make clear that the U.S. and only the U.S. will define what is a “U.S. account” (held by a “U.S. person”).
Interestingly the IRS has offices outside the U.S. (London, Frankfurt, Paris and Beijing). As FATCA becomes fully operational, one wonders whether the IRS will establish more “Local Office(s) Internationally”. FATCA is likely to make the IRS a “U.S. export”.
The U.S. is gradually expanding the number and kinds of people that it deems to be taxable “U.S. persons”. Leaving aside the question of “citizens”, it’s important to realize that U.S. “residents” (which can include people who do NOT reside in the U.S.) are taxable “U.S.persons”.
