Residents versus Nonresidents: US Tax Differences | International Tax Lawyer Minneapolis

There is a huge difference between the US tax obligations of a US tax resident versus nonresident alien. This brief essay strives to outline the main differences in the US tax treatment of tax residents versus nonresidents.

Residents versus Nonresidents: Worldwide Income Taxation

One of the key differences in the tax treatment of residents versus nonresidents is concerning what income is subject to US taxation.  A resident alien is subject to worldwide income taxation similarly to a US citizen. It does not matter where the income is earned, whether it is subject to taxation in a foreign country, whether it has been repatriated to the United States, whether it comes from pre-US funds, et cetera – a resident alien is always subject to worldwide income taxation.

Moreover, a resident alien may also be subject to highly invasive anti-deferral tax regimes such as Subpart F rules and GILTI tax (see below). Under these regimes, a resident alien may have to recognize income that the IRS deems that he earned, but there was no actual distribution.

On the other hand, a nonresident alien may have to pay US taxes on only four types of income. First, US-source income (that the Internal Revenue Code does not otherwise exclude from taxation) that the IRS considers as FDAP income (fixed, determinable, annual or periodical income) under IRC §871(a) (see below more on this subject). Second, a nonresident alien has to pay US taxes on US-source capital gains.  Third, a nonresident alien has to declare on his US income tax returns all ECI (Effectively Connected Income) income from a trade or business within the United States. Finally, certain other US-source and certain other foreign-source income under highly limited exceptions. All other income is excluded from taxation of nonresident aliens.

Residents versus Nonresidents: Deductions

On the other hand, a resident alien has available (at least hypothetically) a far broader range of deductions, including a more expanded list of itemized deductions (for example, mortgage interest, property taxes, et cetera) and a standard deduction.

A nonresident alien, however, has available a far more limited range of deductions.  First, deductions related to the ECI earnings. Second, only three specific kinds of itemized deductions: casualty/theft losses from property located in the United States, charitable contributions to qualified US charities only and one personal exemption (which is a moot point at the time of this writing). Third, a nonresident alien can only claim a standard deduction in the case of a few income tax treaties that allow the claim of a standard deduction; otherwise, the standard deduction is not available.

Residents versus Nonresidents: Tax Filing Status

If a resident alien marries another resident alien or a US citizen, then the couple may elect to file a joint US tax return. Married Filing Jointly is probably the most beneficial tax filing status in the United States.

On the other hand, nonresident aliens (if they want to keep their nonresident status) married to a resident alien or a US citizen can only file as “married filing separately”.  In most situations, this is the most unfavorable tax filing status from the US tax perspective.

Residents versus Nonresidents: US International Information Returns

Compliance with US international information returns is potentially a huge difference between the US tax burden of residents versus nonresidents. A resident alien may be required to file a bewildering array of US international information returns depending on his particular situation.  A failure to do so may result in the imposition of very high IRS penalties.

The main examples of such returns are: FBAR (officially FinCEN Form 114, the Report of Foreign Bank and Financial Accounts), Form 3520, Form 3520-A, Form 5471, Form 8621, Form 8865, Form 8938, Form 926, et cetera.

Residents versus Nonresidents: Tax Withholding on US-Source Income

There are several situations in which a payment to a non-US person may be classified as a US-source income and subject to tax withholding under IRC §§1441 and 1442 solely due to the “US resident” classification of the payor.  Here, I am referring to a situation where the US tax code classifies an interest payment as US-source income only because it is a resident alien made the payment. If such a payment were made by a nonresident alien, then it would be foreign-source income not subject to US tax withholding.

The most common example of such a situation involves interest payments.  Under §861(a)(1), interest paid by noncorporate resident of the United States is US-source income potentially subject to tax withholding. However, if the individual is a nonresident alien for US tax purposes, then the interest is not US-source income exempt from US tax withholding, at least under IRC §§1441 and 1442.

As a side note, I should mention that if the interest made by a US tax resident is classified as “portfolio interest” under §871(h), it would be exempt from the 30% tax withholding pursuant to §§871(a)(1) and 881.  There is also a potential for the exclusion from tax withholding under a particular tax treaty. As always, an international tax attorney should analyze each particular set of facts in its own context in order to determine whether income would be subject to US tax withholding.

Residents versus Nonresidents: Anti-deferral Tax Regimes

A US tax resident may be subject to a wide variety of various US anti-deferral tax regimes, such as PFIC (Passive Foreign Investment Company), GILTI, Subpart F rules, et cetera.

Moreover, a situation may occur where US resident classification as resident under the IRC does not impact this particular individual’s US income tax obligations but may affect such obligations of other US persons.  The most common example is the classification of a foreign corporation as a Controlled Foreign Corporation or CFC. 

Imagine where a person is a US tax resident under the IRC but utilizes the “tie-breaker” provisions of an income tax treaty to continue being classified as a nonresident alien. In this case, this individual’s US income tax obligations are the same as before. However, for the purposes of classifying a foreign corporation as a CFC, he remains a US tax resident. For example, if he owns 10% and the other US owners own at least 41% of this foreign corporation, then the corporation itself will become a CFC without any regard to the treaty provisions. See Reg. §301.7701(b)-7(a)(3).
