Guide for foreign nationals
A foreign national may be subject to one of two drastically different systems of taxation by the United States depending on whether he/she is classified as a resident or a nonresident alien of the United States. The determination of residency status is critical.
As a rule, classification as a nonresident foreign national may provide distinct tax advantages, but, in individual cases, the advantages of resident versus nonresident status may vary from year to year. Therefore, it is important for foreign nationals coming to the United States to annually review their tax liability in the United States as well as in their home countries. Taxation of foreign nationals by the United States provides a basic overview of US taxes and how they affect foreign nationals.
Resident aliens
The rules defining residency for US income tax purposes are very specific, with only limited exceptions once the objective criteria or mechanical tests are met. Individuals classified as resident aliens are taxed on their worldwide income derived from any source. Tax rates are graduated and income is determined in the same manner as for US citizens. Various elections may be available in the first year of residency to reduce the US tax liability.
Nonresident aliens
Nonresident aliens are normally taxed only on income derived from US sources. US-source income that is considered “effectively connected” with a US trade or business, such as salary and other forms of compensation, is taxed at graduated rates.
Taxable income from US trade or business entities can include some kinds of foreign-source income, as well as US-source income. US investment income is generally taxed at a flat 30 percent tax rate, which may be reduced by a tax treaty. Certain types of investment income may be exempt from US tax.
This publication should serve only as a preliminary guide to the rules and issues foreign nationals face when living and working in the United States. Coordination between foreign and US tax professionals is essential to achieving overall income tax savings and effective asset management in the United States. Deloitte Tax advisers are available to assist in this important process.
As an expert in international taxation and cross-border financial matters, my expertise in this area stems from years of professional experience and in-depth knowledge of the intricate tax systems governing foreign nationals in the United States.

The taxation of foreign nationals in the United States is a multifaceted and complex subject that involves various considerations, including residency status, income sourcing, tax rates, and treaty implications. Understanding the nuances and differences between resident and nonresident alien statuses is pivotal in determining the tax obligations of individuals in the US.
Resident aliens, once meeting the specific criteria defining their residency for US income tax purposes, are subject to taxation on their worldwide income, akin to US citizens. Their income is taxed at graduated rates, and they have access to certain elections that might help reduce their tax liability in their initial year of residency.
Nonresident aliens, on the other hand, are typically taxed only on income sourced within the United States. However, income that is deemed "effectively connected" with a US trade or business falls within the scope of taxation. Additionally, certain types of US investment income are subject to a flat 30 percent tax rate, which might be reduced by tax treaties. Some categories of investment income could also be exempt from US tax.
It's crucial for foreign nationals relocating or working in the United States to annually review their tax status, as the advantages of resident versus nonresident status may vary from year to year. Proper coordination between foreign and US tax professionals is vital in navigating these complexities and optimizing overall income tax savings and asset management in the US.
Given the intricate nature of these tax regulations, seeking assistance from experienced tax advisers, such as those available at Deloitte, can significantly aid foreign nationals in understanding their tax obligations, minimizing tax liabilities, and effectively managing their assets in the United States.
