Are US Citizens and Green Card Holders Still Subject to Taxes in the US when Living Overseas?

If you have employees working outside the United States who are US citizens or permanent residents (i.e., a green card holder), these individuals will need to continue filing US tax returns to declare all of the income they earn in both the United States and their Host country. This requirement does not change if they are employed or paid from a non-US employer. Additionally, most of the tax rules that apply to taxpayers living in the United States will also apply to US persons operating overseas. The result may be that an overseas employee will be subject to tax in both the US and other jurisdictions.
