With the United States’ global leadership in finance, pharmaceuticals, and technology, it is a preferred place to do business, making entry into the US market very appealing. When considering doing business in the US, either by opening operations or through e-commerce, non-resident aliens or foreign corporations need to consider potential tax obligations. US tax law includes individuals and business entities not only in all 50 states but also in US territories, though special rules may apply to some territories. It’s important to note that not all business or trust structures in a foreign country translate directly to the US. For example, a trust in one country might be classified as a corporation in the US. In other cases, one can choose the corporate structure in the US for tax purposes, making consultation with a CPA essential.
Nonresident aliens and foreign businesses are subject to US taxes under several conditions. These include income effectively connected with US trade or business, such as business operations, personal services, or gains from the sale of real property. Personal services performed in the US are taxable regardless of duration, while remote services are not unless the provider travels to the US. E-commerce sales without a physical presence in the US are not federally taxable, but state sales tax obligations may arise. Other taxable situations include receipt of fixed or determinable annual or periodic income, gifts or bequests of US property, and estates with US assets. Tax treaties can provide exceptions, reducing tax rates or exempting certain income, but rules against “treaty shopping” apply. Nonresident aliens and foreign businesses must navigate these complex tax rules, often requiring the expertise of a CPA.
