The US taxes its citizens regardless of where their money is earned or where they live. The results of that taxation is a mountain of paperwork that can force US citizens to hire international tax specialists.

The burden of filing international taxes increased in recent years after the Foreign Account Tax Compliance Act became law in 2010.
