Exploring Taxation and Withholding Guidelines for Non-Resident Aliens

In today’s interconnected world, businesses are expanding their reach across borders, employing individuals from diverse nationalities. Among these individuals are non-resident aliens (NRAs), who pose unique tax considerations for both the NRA and the U.S. employer. Understanding the taxation and withholding requirements for NRAs is essential for ensuring compliance and avoiding potential penalties.

Defining Non-Resident Aliens

A non-resident alien (NRA) is an individual who does not meet the requirements to be considered a U.S. citizen or resident alien. These individuals are not subject to U.S. income tax on their worldwide income, but they are subject to U.S. income tax on income derived from U.S. sources.

Substantial Presence Test: Determining NRA Status

The Internal Revenue Service (IRS) utilizes the Substantial Presence Test to determine whether an individual who is not a U.S. citizen qualifies as a resident alien for tax purposes. This test assesses the number of days the individual has been physically present in the United States over a three-year period.

To meet the Substantial Presence Test, an individual must be physically present in the United States for at least:

  • 31 days during the current year, and
  • 183 days during the three-year period that includes the current year and the two years immediately before that.

Days of physical presence are counted in a specific manner, considering the current year, the year before, and the second year before the current year. However, certain days, such as those spent commuting to work from a residence in Canada or Mexico, or those spent in the U.S. for less than 24 hours when in transit between foreign locations, are not counted.

Exemptions from the Substantial Presence Test

Certain individuals are exempt from the Substantial Presence Test, including:

  1. Foreign government-related individuals
  2. Teachers or trainees under a “J” or “Q” visa who comply with their visa requirements
  3. Students under an “F”, “J”, “M”, or “Q” visa who comply with their visa requirements
  4. Professional athletes temporarily in the U.S. to compete in a charitable sports event

Taxation of Non-Resident Aliens Working Outside the U.S.

NRAs working outside the U.S. are generally not subject to U.S. income tax liabilities, withholding requirements, or information reporting requirements. This means that the U.S. employer does not need to issue a Form 1099 to the NRA employee for services performed abroad.

Taxation of Non-Resident Aliens Working Within the U.S.

NRAs working within the U.S. are generally subject to U.S. income tax only on U.S. source income. The type of income and the NRA’s immigration status determine how the income is taxed.

Effectively Connected Income (ECI)

Effectively Connected Income (ECI) is income earned by an NRA from a trade or business in the U.S. It includes wages, salaries, tips, and other compensation for services performed in the U.S. ECI is taxed at the same graduated rates as for U.S. citizens and residents.

Fixed, Determinable, Annual, or Periodical (FDAP) Income

Fixed, Determinable, Annual, or Periodical (FDAP) Income is passive income such as interest, dividends, rents, royalties, and annuities. FDAP income is generally taxed at a flat 30% rate unless a tax treaty specifies a lower rate.

Scholarship and Fellowship Grants

If an NRA is temporarily present in the U.S. under F, J, M, or Q immigration status, portions of scholarship or fellowship grants may be exempt from U.S. tax. However, the portion used for expenses other than tuition and course-related expenses is taxable.

Gambling Winnings and Real Estate Gains

Gambling winnings from sources within the U.S. are generally subject to a flat 30% tax. However, a tax treaty may reduce this rate. Gains from the sale of real property located in the U.S. are also taxable.

Withholding Requirements for Non-Resident Aliens

NRAs working within the U.S. are subject to withholding on their U.S. source income. The employer is responsible for withholding the appropriate amount of tax from the NRA’s paycheck and remitting it to the IRS. The withholding rate depends on the type of income and the NRA’s immigration status.

Form W-4 and Special Adjustments for NRAs

Non-resident aliens (NRAs) are subject to special adjustments on their Form W-4, Employee’s Withholding Certificate, which they provide to their U.S. employer. These adjustments consider restrictions on an NRA’s filing status, ability to claim the standard deduction, and restrictions on claiming certain credits and deductions.

Filing Status Restrictions

NRAs are generally limited to claiming either single or married filing separately (MFS) status on their U.S. income tax return. They cannot claim married filing jointly (MFJ) status unless they are married to a U.S. citizen or resident alien and they both lived together in the U.S. for the entire tax year.

Standard Deduction Limitations

NRAs cannot claim the standard deduction on their U.S. income tax return. Instead, they must itemize their deductions, which can be more complex and time-consuming.

Credit and Deduction Restrictions

NRAs are generally not eligible to claim certain credits and deductions, such as the personal exemption credit, the child and dependent care credit, and the earned income tax credit. They may also have limitations on claiming certain deductions, such as the charitable contribution deduction.

Completing Form W-4 as an NRA

When completing Form W-4, NRAs should:

  • Check the box for “Non-resident alien”
  • Enter their correct alien identification number (AIN)
  • Claim single or MFS filing status
  • Not claim the standard deduction
  • Do not claim any credits or deductions unless they are eligible
